Average asking prices for newly instructed new-build homes in Great Britain edged higher over the year to July, although London and parts of southern England recorded falls.
The average increased from £500,450 in July 2025 to £501,658 in July 2026, according to Propertymark.
Eight regions and nations recorded increases, with the West Midlands seeing the largest rise in cash terms. Its average new-build asking price increased by £33,838, from £384,443 to £418,281.
Yorkshire and Humberside recorded the smallest increase, up £4,848 from £342,998 to £347,846.
Scotland, Wales, the East Midlands, North East, North West and South West also recorded higher average asking prices than a year earlier.
However, prices of newly instructed new-build properties fell in London, the South East and East of England.
The East of England recorded the largest decline, falling £18,713 from £523,714 in July 2025 to £505,001 in July this year.
The South East saw the smallest fall, with its average down £3,300 from £552,109 to £548,809.
Propertymark said regional figures could be affected by factors including the location and type of developments coming to market, planning requirements and material and labour costs.
Nathan Emerson, chief executive at Propertymark, said: “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.”
He added: “Across the entire UK, there is a continued focus on delivering the right homes in the right places. Greater devolution across England could give regions more control over housing policy and help deliver solutions that better reflect local needs.
“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.”
Northern Ireland was excluded from the analysis because of limited data availability.
