Expect to pay between £96 and £175, depending on your property’s location, size, age, and layout. A small flat with simple construction sits at the lower end; a large detached house with multiple heating zones or renewables costs more.

The fee covers pre-visit research, the on-site data collection required under RdSAP 10, and preparing the report afterwards. Watch out for comparison sites advertising low headline prices, a large share often goes to the website rather than the assessor doing the work. Contacting a local accredited assessor directly usually gets you a fairer price and a service tailored to your property.
