The average Barnet home sold for £590,583 in May 2026, down 4.3% in a year (Land Registry). Prices by type, Britain's priciest street, and what it means.

Ask what a home in Barnet is worth and you will get three different answers: the asking price in the agent’s window, the estimate on a portal, and the price homes actually change hands for. Only the last one is recorded as fact, by HM Land Registry when each sale completes, and that is the number this page reads. The short version for 2026: the average Barnet home sold for £590,583 in May 2026, the market is drifting down rather than crashing, and the borough still contains the most expensive street in Britain.

The headline figure for 2026

The average home in the London Borough of Barnet sold for £590,583 in May 2026, the provisional figure from the official UK House Price Index, which is built from completed Land Registry sales rather than asking prices.

That is down 4.3% on a year earlier, when the average stood at about £617,000. The fall has been gathering slowly rather than suddenly: the annual change was -3.8% in March and -3.9% in April before reaching -4.3% in May, even though prices ticked up 0.7% month on month in May itself. Higher mortgage rates have done the work here, thinning out buyers at the top of their budgets, and Barnet is moving with the rest of the capital rather than against it: London as a whole was down 3.7% over the same year while England overall rose 2.3%.

A note on the bigger numbers you will see elsewhere. Rightmove quotes an average for Barnet around £728,000 and Zoopla around £674,000. Those are not wrong, they measure different things: different catchments, different timeframes and a different mix of homes, weighted toward the houses that sell on each portal. The Land Registry figure covers every completed sale in the whole borough, flats included, which is why it reads lower. Always check what area and what mix a house-price figure describes before comparing it with another one.

What a Barnet home costs by type

The borough average hides an enormous spread, wider than almost anywhere outside central London, because Barnet runs from mansion streets in Hampstead Garden Suburb to one-bed flats above the Edgware Road. The May 2026 averages from the UK House Price Index:

Bar chart of average Barnet sold prices by property type in May 2026: detached £1.54 million, semi-detached £831,000, terraced £623,000, all property £591,000, flats £369,000, every category down on the year

  • Detached houses: about £1,540,000, down 4.8% over the year. The smallest category by sales but the one that defines the Totteridge and Hampstead Garden Suburb end of the market.
  • Semi-detached houses: about £831,000, down 3.1%. The classic Barnet family home, from Finchley’s Edwardian streets to the 1930s semis of Mill Hill and Edgware.
  • Terraced houses: about £623,000, down 2.4%. Holding value better than anything else, because they are the most affordable way into a house with a garden.
  • Flats and maisonettes: about £369,000, down 5.9%. The softest corner of the market, hit hardest by mortgage costs and by the volume of new flats being built at Colindale and Brent Cross.

First-time buyers and home movers

The same index splits buyers in a useful way. A first-time buyer in Barnet paid an average of £463,534 in May 2026, down 4.6% on a year earlier. A home mover, someone selling one home to buy the next, paid an average of £772,136, down 3.7%. The £300,000 gap between those two figures is the size of the step from a first flat to a family house in this borough, and it is why so many Barnet moves wait for a school-places deadline before they happen.

Britain’s most expensive street is in Barnet

Barnet’s top end is not just expensive for London, it is the most expensive in the country. Rightmove’s 2026 most expensive streets analysis puts Winnington Road, on the Hampstead Garden Suburb border in N2, at number one in Great Britain with an average asking price of £12,538,095. The Bishops Avenue, the road long nicknamed Billionaires’ Row, is third nationally at £8,930,650. Both figures are asking prices, from streets with at least five homes for sale in January 2026, so treat them as the top of the market talking to itself rather than sale evidence; but no other London borough holds two of the country’s top three streets.

At the other end of the same borough, flats in Colindale, Burnt Oak and parts of Friern Barnet regularly complete below £300,000, which is how one borough produces both a £12 million street and a £369,000 average flat.

How Barnet compares to London and England

Average sold house prices compared, May 2026, UK House Price Index (provisional)
AreaAverage priceChange over the year
Barnet borough£590,583-4.3%
London£544,814-3.7%
England£292,095+2.3%

Barnet sits about £46,000 above the London average and roughly double the England average. The premium is the familiar outer-London bargain: more house per pound than the inner boroughs, with the Northern line and Thameslink into the centre, a long list of well-regarded schools, and green edges at Totteridge, Mill Hill and Monken Hadley. The fact that London fell while England rose is the story of 2026 so far: the adjustment is a capital phenomenon, concentrated in exactly the higher-priced boroughs like this one.

What it means for you

If you are selling, the market is telling you to price on this year’s evidence, not on a 2022 valuation or a neighbour’s asking price. Homes priced against completed sales are still selling, roughly 170 a month borough-wide; homes priced against hope are sitting. If you are buying, a 4.3% annual fall is negotiating room, especially on flats, where the annual fall is nearly 6% and new-build supply at Colindale and Brent Cross keeps sellers honest. Factor in the council tax band of anything you view, since that bill runs at £1,400 to £4,300 a year in Barnet depending on band. If you are staying put, your home is worth a little less on paper than last year and roughly what it was in 2021; after the run prices had before that, a slow leak rather than a fall is the soft version of this adjustment.
