The average asking price for a newly listed newbuild home has climbed to £442,281 – a rise of £15,138 since the summer – according to Propertymark’s latest newbuild report. In July 2025, the figure sat at £427,143, highlighting the continued upward pressure in the newbuild market in some part of the country, led by gains in London and the North West of England.
However, some other areas have seen prices fall sharply. Average house prices for new instructions regarding newbuild properties being marketed in the South West have dropped by £33,120 when compared to a year previously in October 2024, according to the data from Propertymark.
Additionally, Yorkshire and Humberside saw a £33,104 drop during the same period for average house prices for instructions relating to newbuild houses.
Affordability remains a challenge for many people when it comes to buying a property.
With devolved administrations throughout the UK focusing on their own individual housing targets, the Planning and Infrastructure Bill aims to enable the building of 1.5 million new homes in England. Currently, this proposed legislation is working its way through the parliamentary process, as it progresses towards becoming law.
With the upcoming Autumn Budget now firmly on the horizon and with speculation on a potential replacement regarding Stamp Duty for those in England and Northern Ireland, there is a strong possibility for any alternative proposed tax framework to impact newbuild property prices across the forthcoming year.
Average instruction price of newbuild properties and year on year change by individual region.

Nathan Emerson, CEO at Propertymark, said: “With an ever-growing population comes a defined commitment to ensure there is a sustainable mix of new dwellings to keep pace with future demand. Across all nations, various governments have made key pledges to build ambitious numbers of new properties. However, it remains prudent to ensure such homes are designed and built to deliver realistic affordability and better certainty regarding long term pricing trends.
“While the price of raw materials and labour generally trends upwards over time, from a consumer viewpoint, it can appear puzzling to see such year-on-year price fluctuations on new homes coming to the market.
“It is important to consider house pricing is influenced by many complex metrics, which may include the initial cost of the land any such properties are built on, the type of property being constructed, the cost of design, and the intricacies of the planning approval process, as well as the availability of base materials at any particular time, to credit just a few considerations.”
