Basildon's New Town homes gained £56,000. A quarter fewer now sell.

Research by ValuQ: we analysed 9,989 residential sales recorded by HM Land Registry across Basildon borough, comparing the two years to 31 March 2019 with the two years to 31 March 2025, broken down by postcode district and property type.

What did ValuQ find in Basildon?

Basildon borough sold 5,467 homes in the two years to March 2019 and 4,522 in the two years to March 2025. That is a fall of 17.3%, or roughly 472 fewer sales a year. Over the same period the average sale price rose from £330,556 to £394,892, a gain of £64,336.

The borough figure hides a split. Basildon borough covers the New Town postcodes SS13 to SS16, Wickford in SS11 and SS12, and Billericay in CM11 and CM12, and those three places have had very different experiences.

The New Town lost close to a quarter of its sales. Billericay, where homes cost about £192,000 more, lost less than a tenth. Wickford barely moved.

Which Basildon postcode has thinned out the most?

Laindon. SS15 recorded 1,028 sales in the two years to March 2019 and 742 in the two years to March 2025, a fall of 27.8%. It also had the smallest price rise of any Basildon postcode, at 14%.

SS11 is the one part of the borough selling more homes than before the pandemic, up 9.3%. It is also the part with the most new building around Runwell and the northern edge of Wickford. Every other postcode in the borough sells fewer homes than it did.

You can see the underlying sales on ValuQ's Basildon postcode map, which plots every Land Registry sold price on an Ordnance Survey base map with school, station and postcode layers, and in our Basildon house price breakdown by postcode and property type.

Which type of Basildon home is hardest to sell?

Flats. Basildon sold 937 flats and maisonettes in the two years to March 2019 and 728 in the two years to March 2025, a fall of 22.3%. They also gained the least value of any property type, up 11.5% against 23.8% for terraced homes.

A flat owner in Basildon is therefore holding the home that has gained least and become hardest to move. A semi-detached owner is in the steadiest position in the borough on both counts.

Is this only happening in Basildon?

No. ValuQ's nationwide analysis of the same data found that 271 of 305 local authority areas in England and Wales sold fewer homes while prices rose. Basildon ranks 86th of 305 for the size of its fall, so it sits in the worse third of the country but well short of the extremes.

Thurrock and Southend both lost more than a quarter of their sales. Rochford and Brentwood held almost steady. South Essex has not moved as one market.

Why does this matter if you own a home in Basildon?

Because two things are true at the same time, and only one of them shows up in a house price index. Your home is worth meaningfully more than it was before the pandemic. There are also fewer buyers completing purchases in your postcode each year than there were then.

That matters most when you come to price. Rightmove reported on 31 July 2026 that the average move in Great Britain now takes 216 days from listing to completion, the longest at this point in the year since its records began in 2012.

In a thinner market, a price set too high does not get corrected quickly by a queue of viewings. It just sits.

• Fewer local sales means fewer genuine comparable homes, so a valuation based on one or two nearby sales is standing on less than it used to.
• In SS15 and SS13, where sales fell furthest, the gap between an asking price that works and one that stalls is narrower than it was six years ago.
• Getting more than one local agent to price the home gives you the range rather than a single opinion, and the spread between them tells you how confidently the market can be read right now.

ValuQ gives UK homeowners free, side-by-side property valuations from competing local estate agents. You stay anonymous until you choose an agent, and it is free for homeowners, always.

What does this mean for buyers in Basildon?

There is less choice than in 2019 and less competition for each home. A Basildon flat, which is both the cheapest way into the borough and the slowest-moving property type, is where a patient buyer has the most room to negotiate. A seller whose home has been listed through several months of a thin market has a reason to have the conversation.

How we did this

ValuQ analysed 9,989 standard price paid transactions recorded by HM Land Registry in Basildon borough, taken from the Price Paid Data linked-data service on 1 August 2026. We compared two complete two-year windows, 1 April 2017 to 31 March 2019 and 1 April 2023 to 31 March 2025, and split them by postcode district and by property type. Both windows are old enough to be fully registered, which avoids the reporting lag on recent months.

Standard price paid transactions are sales of a single residential property at full market value, so repossessions and bulk transfers are excluded. Average price is the mean sale price of every home sold in each window, which reflects the mix of homes that changed hands as well as their value. The same method was applied to all 305 comparable local authority areas in England and Wales for the nationwide figures quoted here.

Evren Ergin, founder of ValuQ, said:

Basildon owners have been told for years that their homes are worth more, and the data says that is true. What nobody has told them is that a quarter fewer homes in the New Town postcodes are actually finding a buyer. Those two facts belong in the same sentence. If you are thinking of selling in SS13 or SS15, the price on a portal matters far less than whether there is a buyer standing in front of it.
