Optional: start from your energy certificate
Enter your postcode to pre-fill the windows, loft, roof, heating and age from your certificate. You can skip this.
How this works
The checker uses a fixed set of rules based on common building defects and UK energy tables. It is not an AI model and it does not inspect your home. It gives an indicative score and tells you which areas to look at first. A surveyor confirms the real condition.
