Insulation evidence
Cavity wall, loft or floor insulation certificates and guarantees. If it can’t be seen and can’t be proved, the assessment has to assume the worst case.
It’s the one job that stops everything else if you leave it. It’s also the cheapest thing on your moving budget, and the report tells you where your money is worth spending.
A rating from A to G, the rating your home could reach, estimated running costs, and a list of recommended improvements. Buyers read it as a proxy for what the house will cost them to live in.
Most UK homes sit in band D. Your certificate also lists the improvements with the best payback for your house — read it before you spend a penny on insulation or a boiler.
An assessor can only credit what they can see or prove. Paperwork is the difference between a D and a C.

Boiler commissioning records, FENSA or CERTASS certificates for windows, and details of controls like room thermostats and TRVs.
Solar PV, solar thermal, heat pumps or a battery — MCS certificates and inverter details. These move a rating significantly when they’re recorded properly.
Every room, the loft hatch, the boiler and its controls, and the meter cupboard. A locked room or an inaccessible loft costs you points you can’t get back without a revisit.
The cheapest legitimate improvement there is. Swapping remaining halogens for LEDs before the visit costs very little and is credited immediately.
If you’re not sure whether something counts, say so on the day. It’s much easier to record correctly first time than to challenge a lodged certificate.
GuideImproving your ratingYes. In England and Wales you need a valid Energy Performance Certificate before a home is marketed, and your estate agent will ask for it before marketing starts. An EPC lasts 10 years, so check the national register first — you may already have one. If you need a new one, our sister company homesurvey.eu does them for a fixed £75, including lodging on the register.
They do completely different jobs. An EPC rates energy efficiency and is a legal requirement for marketing a home. A survey inspects condition and is what tells you whether the roof is about to cost you £12,000. Most buyers should have both. Find a regulated firm through the RICS register.
