Before the visit
Have the age of the property, any building work history and details of the heating system to hand. Access to the loft, the boiler and any extensions makes the assessment more accurate and quicker.
What is inspected
The building fabric — wall construction, loft and any cavity insulation, glazing and draught-proofing — along with the heating system, hot water arrangements, controls, ventilation and lighting. Nothing is drilled or dismantled; it is a non-invasive inspection.
The certificate
The result is a rating from A to G with a recommendation list. The rating is a summary of the whole building, which is why a single measure rarely transforms it on its own.
How to read the recommendations
Not every recommendation is worth doing for your property. They are ranked by potential impact, but the practical questions — disruption, cost, and what must happen first — are the ones we work through with you.
What to do next
Turn the certificate into a plan: the cheap, non-disruptive work first, then the measures that need a trade on site, sequenced so nothing gets undone.
This guide explains how the work is normally approached. What your property needs depends on its construction, condition and existing systems — a survey is the only way to know for certain.
