House price growth slowed to 2%. What it means for sellers

What did the ONS actually report?

The UK House Price Index is the official measure of house prices. It is built from completed sales registered with HM Land Registry, so it records what buyers actually paid rather than what sellers asked for. On 19 August 2026 the ONS put the average UK home at £272,000 in June 2026, 2.0% higher than a year before.

Annual growth was 3.0% in May, so this is the second month in a row that it has eased. Between May and June prices rose by 0.1%. In the same two months of 2025 they rose by 1.0%.

Why has price growth slowed?

The ONS points at last year's comparison rather than at anything breaking now. Its wording is that the annual rate slowed because price growth has been weaker in early summer 2026 than it was in the same period last year.

Summer 2025 was unusually strong because prices rebounded after the April 2025 stamp duty changes. A weak-looking annual figure this summer is partly a reflection of how busy last summer was.

Are house prices actually falling?

Not in cash terms at UK level. In real terms is a different answer. Real terms means the figure after inflation has been taken off.

CPI inflation was 2.9% in the year to July 2026, reported by the ONS on the same day as the house price data. House prices rose 2.0% over a broadly similar period. The average home therefore bought slightly less than it did a year ago, even though the number on the valuation went up.

Rent growth at 3.7% was the fastest since December 2025. Rents are rising faster than both house prices and inflation, which is why the same week produced headlines about a slowing sales market and a tightening rental one.

Is London different from the rest of the country?

Sharply. London prices fell 2.5% over the year to June 2026, which the ONS describes as the tenth consecutive month of annual falls there, driven mainly by inner London. The North West was the strongest English region at 4.7%.

A national average of 2.0% covers a spread of more than seven percentage points between those two. If you are pricing a home, the national number is the least useful figure in the release.

Why does this feel different from the headlines about falling prices?

Because two different things are being measured. Rightmove reported on 17 August 2026 that average asking prices fell 2% in the month to £364,999, the largest August fall since 2018. That is what sellers are asking today.

The ONS figure is what buyers paid on sales that completed in June, most of which were agreed in spring. Asking prices move first, sold prices follow, and the two rarely agree in the same week.

The national average is the least useful number in a house price release. Your buyer is not buying the United Kingdom.

What does this mean if I am selling this autumn?

1. Price to your own area and your own street, not to the national figure. A 2.0% national rise tells you nothing about a two-bedroom flat in inner London or a family house in Warrington.
2. Expect the buyer to arrive informed. Sold price data is public and free, and buyers read the same slowdown coverage you do.
3. Treat asking price falls as a signal about competition, not about your home's value. Record levels of stock give buyers choice, and choice is what pushes asking prices down.
4. Work out your net figure, not your headline figure. What matters is the amount left after the mortgage, the fees and the moving costs.
5. Get more than one valuation and compare the reasoning behind each one, not only the number at the bottom.

How do I find out what my own home is worth now?

Start with the sold prices on your own street, then get valuations from local agents who are selling in your postcode this month. ValuQ gives UK homeowners free, side-by-side property valuations from competing local estate agents, with your name and number staying private until you decide to connect with one of them.

Comparing several valuations side by side is the fastest way to see whether an agent has priced your home to sell or priced it to win your instruction. In a market where the national average is moving less than a percent a month, that difference is the one that costs money.
