UK-wide home energy audit with personalised efficiency scoring and savings insights. Simple inputs, clear results, and instant guidance for reducing heating costs. Takes under 3 minutes.
This national Home Energy Audit Calculator provides UK households with a personalised, easy-to-understand assessment of heating efficiency, insulation performance, glazing quality, and potential energy savings. Designed for homeowners across England, Scotland, Wales, and Northern Ireland, it uses simplified inputs to generate a clear efficiency score, running-cost estimate, and tailored upgrade recommendations.
Ideal for anyone seeking practical guidance on reducing heating bills, improving comfort, and identifying cost-effective improvements — without needing a full EPC survey.
Efficiency Score
A transparent 0–100 score across heating, fabric, controls, and extras — with band rating A to G.
Savings Recommendations
Tailored upgrade suggestions ranked by impact, difficulty, cost range, and estimated annual saving.
Running Cost Estimate
Estimated annual heating cost based on your property type, fuel, floor area, and age band.
UK-Wide Coverage
Built for homes across England, Scotland, Wales, and Northern Ireland — all property types.
Guide only — not an EPC. This tool is a simplified customer-friendly alternative to a full EPC. Official EPCs use SAP/RdSAP methodology available only to accredited EPC Surveyors through authorised software. Results are estimates based on your inputs and are intended as helpful guidance, not a regulatory certificate.
