A measured EnerGuide evaluation by a registered advisor, and a straight answer about which programmes are open in London.
A large stock of 1950s to 1970s housing where the wall cavity is usually empty or barely filled. Exterior wall insulation is the big-ticket measure and it is the one with the most conditions attached, so get the assessment first.
Checked against each issuing body's own page on 22 Sep 2026. Programmes change without notice, so every one of these links to its source.
A registered energy advisor comes to the house for two to three hours. Every assembly is measured rather than estimated, the mechanical systems are recorded, and a blower door test establishes the actual air leakage rate. That goes into HOT2000, the federal modelling software, and comes back as an EnerGuide rating, a label and a Renovation Upgrade Report listing the measures that would improve it and by how much.
If your programme requires a post-retrofit evaluation — and most of the good ones do — we come back after the work and measure what actually changed. Several programmes require the same advisor for both visits, which is worth knowing before you book the first one.
