Emma Power, COO of Warwick Estates, which analysed the data, said: “Despite the uncertainty posed by the pandemic the UK housing market has boomed and this is no different where the new build market is concerned.

“New build homes have continued to command a price premium in every region of Britain and this is not only good news for those developers delivering them to market, but also to new build homebuyers who continue to see their investment hold its value.

“In the best performing areas, new build property prices are as much as double that of the existing market which is proof of the value being added by the sector to the wider DNA of the national property market.”
