Why this matters
New-build premium sorts towns by how much extra buyers are paying for new stock over existing. A high premium often reflects:
- A tight supply of modern high-spec stock
- Strong demographic demand (family relocation, commuter belt)
- Stamp duty savings specific to new builds (occasionally)
- Shared ownership / Help to Buy price effects distorting average price
A low or negative premium usually reflects a market where the existing stock is already well-priced for the segment, or where recent new-build supply has outrun demand.
For a developer sizing a scheme, the premium figure is a starting point for sales-price assumptions, not a substitute for a proper comparable study.
