Grants verified 20 August 2026. Costs are the register’s indicative ranges, except where marked typical, which this certificate did not price and which are taken instead from comparable homes of the same type. Savings are restated at the fuel prices assumed in July 2026. Points per measure are estimated from 19.9 million certificates and rescaled to this home’s own certificate delta; the total is the register’s figure.
