Heritage Window Cost Calculator UK
“Heritage window” can mean several very different products, from premium flush uPVC designed to imitate traditional joinery to engineered timber or hardwood sash windows. The material and construction method therefore matter more than the label alone.
Quick price answer: A medium premium heritage-flush uPVC example currently centres around £706 fitted, while genuine timber sash products sit in a much higher price tier in the calculator.

These are practical market or calculator benchmarks, not binding installer quotations. Exact dimensions, specification, access and opening condition can move the final price.
Heritage look does not require one material
Flush uPVC can reproduce a more traditional sightline at a lower cost than genuine timber. Timber remains the more authentic choice for many period properties but brings different material, finishing and maintenance considerations.
Listed buildings need separate care
A price estimate does not determine what is permitted. Listed-building consent, conservation-area controls or planning requirements can limit frame material, glazing details and external appearance.
Planning caveat: this page is a pricing guide, not conservation or planning advice. Check the property’s status and local requirements before ordering replacement windows for a listed or sensitive historic building.
