About these prices
Typical UK prices from published price guides, May 2026, ex VAT. We check every figure against its source before it goes on this page. We haven't found reliable published figures for Greater Manchester alone, so local prices may be higher or lower. Once enough homeowners have shared real quotes with us, we'll show local figures here.
