Two Basildon homes, two miles apart, opposite fortunes: your postcode decided it

Research by ValuQ: we analysed more than 1,300 HM Land Registry sold-price records across Basildon postcodes SS13 to SS16 in the year to April 2026, comparing the median sold price in each postcode against the year before. This is part of the ValuQ Property Watch series.

How different are Basildon's postcodes?

Basildon is often treated as one market, but its four postcodes have pulled apart this year. The median sold price is the middle price of all homes sold, so half sold for more and half for less. On that measure, SS13 fell while SS16 held firm and pulled ahead over two years.

Why does the postcode matter so much?

The gap is widest once you look at the same type of home in different postcodes. A detached house sold for a median £490,000 in SS16 but £371,000 in SS13 over the past year. That is a £119,000 difference for the same kind of property a short drive apart, driven by location, school catchments and the mix of homes in each area.

Is this just part of a national trend?

Partly. Flats have been the national weak spot, with Zoopla recording a 1.3% fall in flat values across the UK in the year to May 2026, and SS13 has more terraced and lower-priced stock that has felt the squeeze most. Basildon as a whole is also still 3.2% below its November 2022 peak on the UK House Price Index. But the size of the gap between SS13 and SS16 is a Basildon story, not a national one, and it is the kind of detail a borough average cannot show you.

What does this mean for your own home?

It means the figure that matters is your postcode and your street, not the town headline. ValuQ gives UK homeowners free, side-by-side property valuations from competing local estate agents who know the difference between SS13 and SS16, so you can see what your home is worth today rather than reading across from a borough average. You can also explore every recent local sale yourself on the ValuQ Basildon map.

What it means if you are selling

• Check sold prices for your own postcode, not the town as a whole, before you set an asking price.
• If you are in SS16 or SS15, recent evidence is on your side; price with confidence to the local comparables.
• If you are in SS13, price to this year's market rather than last year's, because homes that chase an old number tend to sit unsold.
• Get more than one valuation, so you can see the local evidence each agent is using.

What it means if you are buying

• SS13 offers the lowest typical prices in Basildon right now and the most room to negotiate.
• SS16 and SS15 command a premium, especially for detached homes, so expect less movement on price there.

A town average is a blunt instrument. Two homes the same size, a couple of miles apart in Basildon, have moved in opposite directions this year. If you are thinking of selling, the figure that matters is not the borough number in a headline, it is what local agents who know your postcode would put your home at today.

How we did this

ValuQ analysed HM Land Registry Price Paid records for Basildon postcodes SS13, SS14, SS15 and SS16, covering more than 1,300 sales in the 12 months to April 2026 and the same number in the prior year. For each postcode we took the median sold price, the middle of all sales, which is less distorted by a handful of very high or very low prices than an average. We then compared the latest year with the year before. Figures are nominal and not adjusted for inflation, and the mix of homes sold can vary between areas.
