At the other end of the market, new-build properties accounted for 0.1% of sales in Stevenage, the lowest proportion of market activity across the nation.
Lee Martin, head of UK for Unlatch, said: “The availability of new homes and the proportion of market activity they account for is always going to differ based on a range of factors including the availability of developments, the time at which they reach the market, their affordability for homebuyers in the area and the profit margins they provide to those building them.
"The latter often means that some areas are always going to benefit from a greater degree of focus from housebuilders and new-build market activity will consistently sit above national and regional averages.
"However, it’s reassuring to see that the new-build sector does account for a healthy level of sales across the board and continues to play a pivotal role in providing the new homes we desperately need.”
