How these tools work
The EPC checker reads your home's certificate from the official GOV.UK register. The heat loss checker uses the UK SAP and RdSAP default U-values. The health checker and the pricers use fixed rules and indicative UK market ranges. They are guides, not quotations. Glaze Home Improvements confirms everything with a free survey and gives you a written price.
