The average asking price of a newly instructed new-build property increased by just 0.2% over the year to July, latest Propertymark data reveals.
Across Great Britain, the average rose by £1,208, from £500,450 in July 2025 to £501,658 in July 2026.
However, the headline figure masks substantial regional variation, with prices increasing across eight of the 11 areas analysed while falling in London, the South East and East of England.
The figures relate to asking prices when properties were newly instructed rather than achieved sale prices and may be affected by changes in the location, size and type of developments entering the market.
WALES RECORDS LARGEST INCREASE
Despite Propertymark’s accompanying release identifying the West Midlands as recording the largest increase, its published figures show that Wales experienced the biggest rise in both cash and percentage terms.
Average new-build asking prices in Wales increased by £43,494, or 12.9%, from £338,222 to £381,716.
The West Midlands recorded the next-largest cash rise, increasing by £33,838, or 8.8%, to £418,281. Prices in the North East also rose by approximately 8.8%, reaching £345,867.
Yorkshire and Humberside recorded the smallest increase, with average asking prices rising by £4,848, or 1.4%, to £347,846.
SOUTHERN REGIONS DECLINE
The East of England experienced the largest fall, with average new-build asking prices dropping by £18,713, or 3.6%, to £505,001.
London remained the most expensive market at £839,100 despite recording an annual decline of £6,766, or 0.8%.
The South East experienced the smallest decrease, falling by £3,300, or 0.6%, to £548,809.
“Every nation faces its own housing challenges.”
Nathan Emerson (main picture, inset), CEO at Propertymark, says: “While these figures show an overall year-on-year rise in the average asking price of many new-build properties, regional disparities remain, making it more challenging for some aspiring homeowners to get onto the property ladder.
“With the Budget due on 28 October 2026, any housing-related announcements will be closely watched, particularly measures aimed at helping more first-time buyers purchase a home.
“Every nation faces its own housing challenges, and addressing them will require ambitious, targeted policies to better balance housing supply and demand over the long term.”
