Hillingdon is a borough on the western edge of London. Average sold prices across Hillingdon sit at £469,888 on the HM Land Registry House Price Index, 62.1% above the England average of £289,946 but 15.0% below the wider London figure of £552,655. That gap is the whole story of the borough: Hillingdon is the affordable end of London, where the average home costs less than in almost every inner borough yet still sits well clear of the national figure. Its cheapest postcode, UB3 in Hayes, carries a £402,934 asking price, which is what makes the borough a route into London property at a price a great many other parts of the capital have left behind. The local population grew 11.67% between the 2011 and 2021 censuses, from 273,936 to 305,909 residents, faster than the England and Wales average.

What sets Hillingdon apart from the corrected inner-London markets is that it has held its ground. The borough reached an all-time high of £482,624 in August 2025 and has eased only gently to £469,888 since, leaving prices up 7.8% over five years where many central boroughs are flat or down. Top gross yields reach 5.6% in UB3, the joint-cheapest and highest-yielding postcode, while the dearer Ruislip and Harefield postcodes yield closer to 4.0%.

This guide covers the London Borough of Hillingdon (ONS code E09000017) across postcodes UB3, UB4, UB7, UB8, UB9, UB10, and HA4. Hillingdon stretches across outer west London from Hayes and West Drayton on the Heathrow fringe up through Uxbridge to Ruislip and Harefield in the north, bordering Ealing to the east and Hounslow to the south.

Why Invest in Hillingdon?

Hillingdon added 31,973 residents between the 2011 and 2021 censuses, an 11.67% rise from 273,936 to 305,909, nearly double the 6.3% England and Wales average and ahead of its outer-west neighbours Harrow and Havering. The borough is the second-largest in London by area, a wide band of suburban west London that runs from the dense, diverse town of Hayes near Heathrow up through the market town of Uxbridge to the greener, house-heavy streets of Ruislip and the semi-rural edge at Harefield. That spread from airport-fringe flats to outer-suburban houses is what gives Hillingdon its range, and it runs through every table in this guide.

The local employment rate of 74.0% sits just below the London figure of 74.9% and the Great Britain figure of 75.6%, and unemployment runs at 7.7%. Heathrow Airport, which sits on the borough's southern edge, anchors the local economy and draws a large workforce in logistics, aviation, hospitality and freight into the southern postcodes, while Uxbridge serves as the administrative and retail centre with Brunel University on its doorstep. For a landlord, the practical read is that tenant demand here is steady and varied, spanning airport and warehouse workers in Hayes and West Drayton, students and graduates around Uxbridge, and settled family renters in the northern suburbs.

Median gross weekly earnings for Hillingdon residents are £812.50, which works out at £42,250 a year. That sits below the London median of £892.60 a week but well above the Great Britain figure of £752.40. Those mid-range wages, paired with the borough's relatively low asking prices, are part of why Hillingdon rents hold up: a household here can cover a £1,658 to £1,983 monthly rent on local pay more comfortably than in the higher-priced inner boroughs. The Elizabeth line, which runs through the borough to Heathrow, has also pulled in commuters who want a faster route into central London than the borough's price tag would suggest.

Regeneration and Investment in Hillingdon

Hillingdon shares the Heathrow Opportunity Area with Hounslow, a growth corridor designated for 13,000 new homes and 11,000 new jobs by 2041, anchored on the airport on the borough's southern edge. The investment story here is one of connectivity and employment rather than the dense residential masterplans of inner London, and it concentrates in the southern postcodes nearest Heathrow and the Elizabeth line.

• Heathrow Opportunity Area (Long-term, 13,000 homes and 11,000 jobs by 2041): The Mayor of London designated the Heathrow Opportunity Area in 2008, covering land across Hillingdon and Hounslow as part of the Heathrow and Elizabeth line West growth corridor. The plan supports up to 13,000 new homes and 11,000 new jobs by 2041, with the airport and its supply chain the engine of local employment. This sits behind the southern Hillingdon postcodes of UB3, UB4 and UB7. Details at London City Hall.
• Elizabeth line connectivity (Operational): The Elizabeth line runs west through the borough to Heathrow, giving southern Hillingdon a direct, fast rail link into the West End and the City without a change. For a borough at the affordable end of London, a turn-up-and-go connection to central London is the kind of transport upgrade that usually arrives with a higher price tag attached.

Hillingdon Property Market Analysis

Average property prices in Hillingdon have risen 519.8% since January 1995, from £75,819 to £469,888. The sections below trace that path through the borough's actual cycles, then break down current postcode-level data for sold prices, price per square foot, asking prices, growth trends, and monthly transaction volumes.

When was the last house price crash in Hillingdon?

Hillingdon's sold prices are recorded by HM Land Registry at borough level under ONS code E09000017, and the House Price Index runs from January 1995 to the latest reading in April 2026, covering 31 years of market cycles. Unlike the inner-London boroughs that boomed and corrected after 2020, Hillingdon's sharpest move was the 2008 crash, and its more recent record has been one of steady gains rather than a give-back.

The 1995 to 2008 climb: Hillingdon started at £75,819 in January 1995. Outer-London demand carried it past £141,485 by December 2000 and £229,967 by December 2005. The pre-crash market topped out at £274,043 in January 2008, more than three and a half times its 1995 level.

2008 to 2009, the financial crisis: Prices fell from the January 2008 peak of £274,043 to a trough of £224,599 in April 2009, a drop of 18.0% over 15 months, with the worst year-on-year reading at -16.5% in March 2009. The decline tracked the wider London and England falls of around 18%, hitting the borough's terraced and flat stock hardest.

Recovery, 2009 to 2012: The bounce was steady rather than sharp. Prices climbed back through 2010 and 2011 and passed the January 2008 pre-crash peak by October 2012, when the average reached £275,338. That recovery took about three and a half years, faster than many regional markets but slower than the inner-London boroughs that rebounded first.

2012 to 2016, the catch-up surge: This was Hillingdon's strongest stretch. Prices ran from £273,896 in December 2012 to £422,536 by December 2016, a rise of more than half in four years, as London's price ripple finally reached the outer west and buyers priced out of nearer-in boroughs looked further along the line.

2017 to 2019, the plateau: Growth stalled. The average eased from £422,536 at the end of 2016 to £415,025 by December 2019, as stamp duty changes and wider London uncertainty cooled the outer market along with the rest of the capital.

2020 to 2025, the renewed climb and recent high: The borough picked up again, passing £436,937 by December 2020 and climbing to an all-time high of £482,624 in August 2025. That August 2025 reading remains the highest in the borough's 31-year record.

2025 to present, a gentle easing: Since that high the market has softened slightly, slipping to £469,888 by April 2026, about 2.6% below the August 2025 peak. That is a mild cooling rather than a correction, and it leaves Hillingdon up 7.8% over five years while many inner-London boroughs sit flat or lower.

Long-term growth summary:

• 5 years (April 2021 to April 2026): 7.8% growth (£436,011 to £469,888)
• 10 years (April 2016 to April 2026): 16.0% growth (£405,061 to £469,888)
• 15 years (April 2011 to April 2026): 82.1% growth (£258,016 to £469,888)
• 20 years (April 2006 to April 2026): 102.4% growth (£232,183 to £469,888)
• 30 years (January 1995 to April 2026): 519.8% growth (£75,819 to £469,888)

The shape of those numbers is the key to Hillingdon today. Where inner-London markets posted huge gains then gave a chunk back, Hillingdon's climb has been later and steadier, with a positive five-year and ten-year reading rather than the flat-to-negative figures further in. An investor here is buying a borough that has kept rising at lower asking prices, with the recent easing from the 2025 high offering a softer point to come in.

Sold House Prices in Hillingdon

The average sold price across all property types in Hillingdon is £469,888, which is 62.1% above the England average of £289,946 as of April 2026. The premium narrows sharply with the size of the home: detached houses cost 100.4% more than the England average, while flats, the cheapest way into the borough, cost just 32.8% more. That spread reflects a borough where suburban houses set the headline figure and flats keep the entry point within reach.

Detached houses at £942,742 are 100.4% above the England average, and they cluster in the greener northern postcodes of Ruislip, Ickenham and Harefield where larger plots and inter-war housing dominate. They posted modest annual growth of 0.2%, holding steady at the top of the market.

Semi-detached houses at £581,623 carry the widest premium of the four types at 101.8% above England, and they are the backbone of suburban Hillingdon, the inter-war and post-war family homes that line streets across Uxbridge, Hayes and Ruislip. They grew 1.4% over the year, the second-strongest of the four types.

Terraced houses at £456,622 sit 87.3% above the England average. The borough's terraces run through the older parts of Hayes, Uxbridge and West Drayton, the more affordable house end of the market, and they posted the firmest annual growth at 0.9%.

Flats and maisonettes at £284,936 are just 32.8% above England, by far the narrowest premium of the four and the part of the market that keeps Hillingdon accessible. Flats concentrate in Hayes and around the southern Heathrow-fringe postcodes, so the all-property average of £469,888 sits well above the flat figure but the flat market is where most income investors will start. Flat values fell 3.7% over the year, the only type to decline, which is why the headline all-types reading dipped slightly while the houses held.

Price Per Square Foot in Hillingdon

£105 per square foot separates Hillingdon's cheapest postcode from its dearest, with UB7 at £492 and HA4 at £597. Pricing by the square foot sets aside the size of the homes and reads the value of the location alone, which in Hillingdon rises steadily as you move north from the Heathrow fringe towards the leafier suburbs. HA4 in Ruislip tops the table, where established residential streets carry the borough's highest rate for space.

UB7 at £492 per square foot is the most affordable space in the borough, covering West Drayton on the western edge near the airport. Based on 384 transactions analysed, its rate sits about 18% below HA4's, the trade-off being a less established residential setting than the northern suburbs.

HA4 at £597 per square foot tops the table from 763 transactions, the largest sample in the borough, with UB10 next at £565. Ruislip's mature, house-dominated streets command the highest rate per square foot in Hillingdon, while UB10, covering Hillingdon village and Ickenham, carries a similar northern-suburb premium for space.

For Sale Asking Prices in Hillingdon

UB3 at £402,934 and UB9 at £569,048 sit 41.2% apart, the full width of Hillingdon's asking-price range. The hierarchy splits the borough into a cheaper southern band around Hayes, West Drayton and Uxbridge and a dearer northern band through Ickenham, Ruislip and Harefield. The mean asking price across all seven postcodes is £482,012.

UB3 in Hayes at £402,934 is the cheapest way into the borough, almost level with UB7 in West Drayton at £402,971, and the two are effectively the joint entry point for a buyer working to a budget. Both sit below the borough's Land Registry sold average of £469,888 and both feed off the Heathrow fringe and the Elizabeth line.

UB9 at £569,048 is the most expensive, the semi-rural Harefield and Denham market at the northern edge of the borough where larger detached homes and a greener setting carry the price. The £166,114 step from UB3 to UB9 buys more space and a quieter location rather than a more central one, and the yield tables below show what that does to the income return.

House Price Growth in Hillingdon

UB10 leads Hillingdon's recent growth with a five-year return of 23.2%, while UB9 sits at the other extreme down 3.4% over the same period. The growth table shows a borough rising broadly rather than splitting in two: six of the seven postcodes posted positive five-year growth, an unusually consistent picture for London.

UB10 (Hillingdon, Ickenham) posted a five-year return of 23.2% alongside 7.0% over the past year, the strongest performer in the borough. The northern suburban postcode benefited from the broad shift of buyers towards more space and greener settings, and it has carried that gain through to the present. UB4 (Hayes, Yeading) follows at 20.0% over five years and 11.5% over three, its growth concentrated in the more recent windows as the Hayes regeneration and Elizabeth line drew renewed demand.

UB9 (Harefield, Denham) is the one postcode down over five years at -3.4%, though it has recovered ground recently with a 10.5% one-year reading. The small, thinly traded semi-rural market at the borough's edge moves differently from the suburban core, a reminder that the dearest postcode by asking price is not always the steadiest performer.

Monthly Property Sales in Hillingdon

Hillingdon records around 150 sales a month across its seven postcodes, with HA4 (Ruislip) the busiest at 32 and UB9 (Harefield, Denham) the quietest at 13. Transaction volumes and turnover vary across the borough, which shapes how easily an investor can buy now or sell later.

HA4 is the busiest market at 32 sales a month on 8% turnover, a deep Ruislip postcode where homes change hands regularly across its surrounding suburbs. That volume gives a buyer more choice and a wider set of recent sales to price against, and points a future seller towards a quicker exit. UB10 in Hillingdon and Ickenham follows on 25 sales a month at the highest turnover in the borough at 9%, where stock moves a little faster than elsewhere.

UB9 in Harefield and Denham is the quietest at 13 sales a month, a tightly held semi-rural market where larger homes rarely come up. That scarcity gives a buyer little to choose from and leaves each sale harder to price against, since comparable evidence is thin. The selling-times section below sets out how those volumes translate into how long a sale actually takes.

How Long Properties Take to Sell in Hillingdon

UB9 (Harefield, Denham) is the only Hillingdon postcode that reads as a balanced market, clearing in about 338 days, while the Hayes and West Drayton postcodes UB3 and UB7 sit for roughly 507 days with nearly 17 months of unsold stock. Days on market is the typical time a home is listed before it sells, and months of unsold stock measures how much for-sale supply is queued at the current pace. A yield figure says nothing about how long your money is tied up at the end, and in Hillingdon that exit cost runs from under a year to nearly a year and a half. The table is ranked fastest first.

UB9 in Harefield and Denham clears fastest at about 338 days and 11.1 months of supply, the only postcode that registers as balanced rather than a buyer's market, despite being the quietest on volume, because its for-sale stock is tight relative to the sales it does see. The Ruislip, Uxbridge and Ickenham postcodes group together at around 380 days, a steady outer-suburban pace. At the slower end, UB3 and UB7 around Hayes and West Drayton carry 16.7 months of unsold stock and take roughly 507 days to sell, half as long again as UB9. For an investor the cheaper southern postcodes mean real room to negotiate on the way in, but a longer wait whenever the time comes to sell, so the lower asking price has to be weighed against the holding cost on exit.

What Type of Property Can You Buy in Hillingdon?

The stock mix swings from house-dominated Harefield, where detached homes alone make up 43.1% of UB9, to flat-heavy Hayes, where purpose-built flats account for 36.0% of UB3. The mix is one of the most important facts about Hillingdon for a buy-to-let investor: this is a borough of suburban houses with a genuine flat market only at the southern, Heathrow-fringe end. The figures below are drawn from 2021 Census records for each postcode.

UB9 in Harefield is the most house-heavy postcode, with detached homes alone at 43.1% and semi-detached at a further 19.7%, the semi-rural northern edge where larger plots dominate and flats are scarce. UB10 and HA4 follow the same suburban pattern, with semi-detached the single largest type in Ruislip at 34.3%. These are the family-house postcodes, with relatively little for an investor chasing a flat.

UB3 in Hayes is the outlier at the other end, where purpose-built and converted flats together reach 40.9%, the highest flat share in the borough, and detached houses fall to just 5.7%. UB8 and UB7 sit in the middle at around a third flats, with UB4 closer to a quarter. A buyer wanting a flat in Hillingdon is effectively shopping in the southern Hayes, West Drayton and Uxbridge postcodes, while the houses concentrate to the north.

Flats combine purpose-built blocks and converted units, and a small share of other dwelling types is left out, so rows may not total 100%.

Hillingdon Rental Market Analysis

Monthly rents in Hillingdon range from £1,658 in UB8 to £1,983 in UB10, with gross rental yields from 4.0% to 5.6% across the seven postcodes. For investors weighing whether buy to let is worth it in an outer-London borough that has kept rising, the income return and the affordable asking prices both carry weight, and the sections below break down rents, yields and tenant affordability postcode by postcode. Browse current buy-to-let homes for sale across the capital.

Average Rent & Gross Rental Yields in Hillingdon

Gross rental yields in Hillingdon run from 4.0% in UB9 to 5.6% in UB3. Yield climbs as the asking price falls, so the cheaper Hayes and West Drayton postcodes in the south return more income than the dearer Ruislip and Harefield postcodes in the north. UB3 pairs the borough's joint-lowest asking price with a £1,869 rent to top the table.

UB3 tops the yield table at 5.6%, the only postcode above 5%, pairing the borough's joint-lowest asking price of £402,934 with a £1,869 monthly rent in Hayes. A 30% deposit there is £120,880, the lowest figure in Hillingdon. UB7 in West Drayton follows at 4.9%, the next cheapest entry, where the same low asking price meets a slightly lower rent.

UB9 in Harefield and Denham sits at the bottom of the yield table at 4.0%, where a £569,048 asking price meets a £1,917 rent. The semi-rural northern postcodes hold their appeal as quieter, greener places to live, but the income return is compressed by purchase prices the rent does not keep pace with, the trade-off for buying into the part of the borough with the most space.

Is Hillingdon Rent High?

Hillingdon rents consume between 47.1% and 56.3% of the local median individual salary, above the 30% affordability benchmark but lower than the inner-London boroughs where rents take two-thirds of a salary or more. The common rule of thumb is that rent should take around 30% of gross income. No Hillingdon postcode meets that on a single median salary, but the gap is narrower here than nearer the centre, which is part of the borough's appeal to renters.

The median gross weekly salary in Hillingdon is £812.50, which works out at £3,521 per month or £42,250 per year. That sits below the London median of £892.60 a week but well above the Great Britain median of £752.40. Data from the Nomis Labour Market Profile (ASHE 2025).

These figures compare a one-bedroom-or-larger market rent against a single resident's median pay, so they read high by design. In practice Hillingdon's renters are mostly couples and sharers pooling two or more incomes, which is how a borough with rents around £1,900 a month sustains the demand it does. UB8 in Uxbridge at 47.1% is the most affordable on this measure, where one of the borough's lower rents meets the same median salary.

How Big Is Hillingdon's Private Rented Sector?

The private rented sector is deepest in the southern Hayes and West Drayton postcodes, where it reaches 38.8% of households in UB7 and 36.5% in UB3, and shallowest in the northern suburbs at 17.9% in Harefield's UB9. The share of homes already rented privately is a guide to how large and established the local tenant pool is, and in Hillingdon it splits cleanly between the airport-fringe south and the owner-occupier north. The table below shows household tenure by postcode.

UB7 and UB3 hold the largest private rented sectors at 38.8% and 36.5%, the southern postcodes around West Drayton and Hayes where renting is the default tenure for the airport and warehouse workforce who fill the flats near Heathrow and the Elizabeth line. With well over a third of homes already let privately, those postcodes carry a proven, working tenant base rather than an untested one.

The picture flips to the north. UB9 in Harefield reaches 41.3% outright ownership and the private rented share drops to 17.9%, with UB10 and HA4 close behind, settled owner-occupier suburbs where renting is the minority tenure. Social renting is modest across most of the borough, running from 8.8% in Ruislip up to 21.6% in Hayes. That split is why tenant demand in Hillingdon concentrates in the south, where the established rental market and the highest yields sit together.

Local Housing Allowance Rates in Hillingdon

Hillingdon straddles three Broad Rental Market Areas, so the Local Housing Allowance rate depends on the postcode: most of the borough falls in Outer West London, Ruislip's HA4 sits in North West London, and Harefield's UB9 falls in the Chilterns area. Local Housing Allowance is the most a tenant on housing support can claim towards rent, so for that part of the market it sets an effective floor. To check the figure for a specific address, use the government's official Local Housing Allowance calculator.

Across most of the borough, the Outer West London two-bedroom rate of £299.18 a week works out at about £1,296 a month, well below Hillingdon's open-market rents of £1,658 to £1,983. The North West London rates that apply in Ruislip run a little higher, and the Chilterns rates covering Harefield a little lower, but in every part of the borough a benefit-backed tenancy at the LHA rate sits some way under market rents. Given Hillingdon's mix of lower-income airport and logistics households in the south, the LHA floor matters most in the Hayes and West Drayton postcodes. These rates are the June 2026 figures and are reset each April.

Buy-to-Let Considerations

Are House Prices High in Hillingdon? Price-to-Earnings Ratios

Buying in Hillingdon takes between 9.5 and 13.5 times the local median salary, above the national benchmark but among the more accessible ratios in London. This is based on the Nomis Labour Market Profile for Hillingdon, which puts the median gross annual income for residents at £42,250.

The national benchmark for price-to-earnings is 7.4x (England's average sold price of £289,946 divided by the Great Britain median annual salary of £39,125). No Hillingdon postcode reaches that, but the borough's lower ratios are closer to it than the inner-London boroughs, where the figure often runs past 14x.

UB3 and UB7 are the most affordable on this measure at 9.5x, the joint-cheapest postcodes around Hayes and West Drayton. Even the cheapest way into Hillingdon takes more than nine years of the local median salary, a reminder that London buyers rarely rely on a single local wage, but the ratio sits well below the borough's inner neighbours.

UB9 in Harefield at 13.5x is the least affordable, with HA4 in Ruislip just behind at 13.1x. The two reach that point through the value of the borough's northern house market, where larger detached and semi-detached homes carry the price. Both sit at the bottom of the yield table for the same reason, a purchase price the rent struggles to keep up with.

Deposit Requirements in Hillingdon

A 30% deposit on a buy-to-let in Hillingdon ranges from £120,880 in UB3 to £170,714 in UB9. The £49,834 gap between the cheapest and dearest deposit reflects the spread from the Hayes flats in the south to the Harefield houses in the north. For investors comparing Hillingdon with the rest of London, these deposits sit among the lowest of any London borough, below the outer-east and inner-south markets and far below the prime western neighbours.

Beyond the deposit, the stamp duty calculation and other buy-to-let running costs add materially to the capital required, particularly the surcharge on additional property, which runs into five figures at Hillingdon's price points.

UB3 keeps the upfront cost down at a £120,880 deposit, and UB7 is within about £11 of it. Hayes and West Drayton are where a budget-conscious investor starts in Hillingdon, pairing the two lowest deposits with the two highest yields in the borough at 5.6% and 4.9%.

At the top, UB9 needs a £170,714 deposit, around £49,800 more than UB3, for a postcode that earns less per pound through the rent. The extra deposit buys a larger home in a greener northern setting rather than a higher yield.

What the Hillingdon Data Tells Buy-to-Let Investors

In Hillingdon the cheapest postcodes are also the highest-yielding. UB3 (Hayes) carries the top yield at 5.6% and is the joint-cheapest way in, at a £402,934 asking price for an investment property in Hillingdon, and among the most affordable against local earnings at 9.5 times income. A 30% deposit there is £120,880, the lowest in the borough, for a home renting at £1,869 a month, with the Heathrow Opportunity Area and the Elizabeth line on its doorstep.

The borough divides north to south rather than splitting cleanly in two, and the data draws the line. The southern Heathrow-fringe postcodes, UB3, UB7 and UB8, run the higher yields, the lower prices and the deepest rental markets. The northern suburban postcodes, UB9, UB10 and HA4, cost more and yield less but offer houses, space and the borough's steadiest owner-occupier demand. Income points south to Hayes and West Drayton; space and family-let demand point north to Ruislip and Harefield.

The house-led stock is the defining feature across most of the borough. Detached and semi-detached homes dominate five of the seven postcodes, and the all-property sold average of £469,888 sits well above the flat figure of £284,936, so the headline price reflects a suburban house market. Only in the southern Hayes and West Drayton postcodes does a genuine flat market exist, and that is where the highest yields and the deepest tenant pools sit together.

Set against the rest of London, Hillingdon is the affordable end of the capital and one of the few boroughs still up across the windows: up 7.8% over five years and up 16.0% over ten, where many inner boroughs are flat or down. It combines that recent capital growth with London exposure and the lowest deposits in the city. With most postcodes registering as buyers' markets, there is room to negotiate on the way in, and the keenest prices tend to sit in below market value and off-market property channels rather than on the open portals.

How Hillingdon Compares

Hillingdon's mean asking price of £482,012 is the lowest of its outer-west London neighbours, undercutting Hounslow, Ealing, Harrow and Brent, while its top yield of 5.6% sits at the value end of the group. The comparison below sets Hillingdon alongside four nearby boroughs, each with a different balance of price and income return. Mean asking price and mean monthly rent are simple averages across all postcodes with data, and top gross yield is the single highest postcode yield in each borough.

Hillingdon is the cheapest of the five at £482,012, around £30,000 below Hounslow and more than £70,000 below Brent, the most expensive in the group. That makes it the lowest-deposit entry into outer-west London, while its 5.6% top yield matches Brent and sits just shy of the 5.7% in Hounslow and Ealing.

The income returns are tightly bunched across the group, from Harrow's 5.4% to Hounslow and Ealing's 5.7%, so the clearest difference is price. Hillingdon and Hounslow share the Heathrow Opportunity Area and the value end of the table, while Ealing, Harrow and Brent carry higher prices for their nearer-in positions and stronger Elizabeth line and Metropolitan line links. For investors prioritising the lowest entry cost in west London, Hillingdon makes the case; for those wanting a more central position, the premium over Hillingdon buys it.
