UK New Build Premium Report Q1 2026

10,043 new build transactions analysed. County-by-county premium rankings.

01

The New Build Premium Landscape

Across 48 counties, 10,043 new build transactions were recorded in the past 12 months — representing 2.2% of all residential sales. But the premium buyers pay for new build over existing stock varies dramatically by location.

This report analyses the average new build premium at county level, revealing where developers can command the highest margins — and where new build stock is, surprisingly, selling at a discount to existing properties.

A negative new build premium does not necessarily indicate a poor market for developers. It often reflects the mix of new build stock — for example, a county dominated by new-build flats will show a lower average price than one dominated by detached houses. Context matters.

04

Implications for Development Appraisals

The new build premium is a critical input to any development appraisal. In counties where premiums exceed 15%, developers can afford to pay more for land and still achieve target margins. Where premiums are thin or negative, the focus shifts to build cost efficiency and exit strategy.

Lenders structuring development finance will scrutinise the assumed end values carefully. In high-premium counties, comparable evidence for new build pricing is readily available. In low-premium areas, valuers may take a more cautious approach.

05

Funding Your New Build Scheme
