New mortgage rules fuel buyer activity – what it means for developers

Aug 12, 2025

The UK housing market is avoiding its usual summer slowdown. Recent mortgage affordability changes mean homebuyers can now borrow up to 20% more than three months ago. That extra buying power is keeping demand strong.

Zoopla reports buyer numbers in July were 11% higher than last year. Sales agreed are up 8%. More homes are on the market, especially in southern England. This is holding back price growth and creating a real buyer’s market.

For developers, the takeaway is simple. Increased buyer activity means well-priced, ready-to-go homes will move faster. Scotland, Wales, and northern England are seeing annual growth of 2–3%. Much of the south is rising more slowly.

Mortgage rates remain steady. The average UK house price now sits at £268,400. Regional trends matter – strong demand in some areas could speed up new build sales. Softer markets may need sharper pricing or added incentives.
