ValuQ Property Watch: Basildon flats fell 6% as terraces rose

Research by ValuQ: we analysed 2,923 Basildon home sales recorded on HM Land Registry's Price Paid data, split by property type across two years, to see what the town's flat headline price was hiding.

What did the national house price figures say this week?

In the first week of June 2026 the three main UK house price indices all told a similar, quiet story. Nationwide put annual growth at 1.7% on 1 June. Halifax reported on 5 June that the average home edged down 0.1% in May to £298,806, with annual growth of 0.5%. Zoopla had annual growth at 1.5% in late May, with buyer demand down 10% on a year earlier.

Read together, the indices disagreed by about 1.2 percentage points. That is the national argument in a sentence: is the market up nearly two percent, or barely half a percent? It is a narrow band, and it makes the housing market sound calm.

What is actually happening to Basildon house prices?

A house price index is a single average that smooths every home in an area into one number. Basildon's own number looks exactly as calm as the national ones. The median price of a home sold in the town was £320,000 in the year to March 2026, unchanged from the year before. But a town does not have one housing market. It has several, one for each type of home, and in Basildon they moved in opposite directions.

Terraced homes, the workhorse family house that makes up almost half of all Basildon sales, were the only type to rise. Flats fell hardest, down 6.3%. Detached homes, the top of the local market, slipped 4.7%. The mainstream held its value; the cheapest and the most expensive ends both softened.

Why does the town average hide all this?

Because an average is a blend, and the pieces of the blend cancel out. Terraced prices rising roughly offset flats and detached homes falling, so the town median landed back at exactly £320,000. The single number was not wrong. It was just empty: it described no actual home that sold in Basildon last year.

A seller does not own the average. They own one home, of one type, on one street, and that is the only number that pays their next move.

The gap between Basildon's strongest and weakest property type last year was 8.6 percentage points. The gap between the national indices that filled the headlines this week was 1.2 points. The real spread, the one that decides what a seller actually banks, was about seven times wider than the one everyone was arguing about, and it was hiding inside a single town.

What does this mean if you are selling in Basildon?

• If you own a terraced house, the past year was on your side. Demand for mainstream family homes held up and prices edged ahead.
• If you own a flat, do not price off the town average or off a neighbour's house sale. Your part of the market fell, and a realistic asking price sells while an aspirational one sits.
• If you own a detached home, the top of the market cooled. Buyers at that level have more choice and are negotiating harder.
• Sales volumes fell about 18% across the town, from 1,605 to 1,318. Fewer buyers are active, so the right price and a strong local agent matter more, not less.

Evren Ergin, founder of ValuQ, said: "The headline number tells a flat owner in Basildon that prices barely moved. Their own market fell six percent. That gap is the whole problem with averages. The job is to value the home in front of you, not the town."

This is the case for seeing real numbers, not a blended one. ValuQ gives UK homeowners free, side-by-side property valuations from competing local estate agents, so a seller sees what their actual home is worth, of their type and on their street, before they commit to anyone.

How we did this

ValuQ analysed every residential sale recorded in the town of Basildon on HM Land Registry's Price Paid data for the 12 months to 31 March 2026 (1,318 sales across the four standard property types) and the 12 months before that (1,605 sales). We compared the median sold price for each property type across the two periods. Medians are used so that a handful of very high sales do not distort the figure. The most recent weeks of Land Registry data are still being registered, so the latest months will fill in a little over time. Commercial and other non-standard transactions are excluded.
