How to explain an EPC to a homeowner
A practical guide for domestic energy assessors, written by a former DEA.
Most follow-up calls after an EPC come down to the same few questions: what does the rating mean, why is it lower than I expected, and what should I do first? Answer those in plain words and you save yourself the call, and your customer trusts the certificate.
1. Start with the rating and the potential
Give the band and the score together ("D, 67"), then the potential ("it could reach B, 83, with the recommended steps"). The gap between the two is what the homeowner cares about, so lead with it.
2. Explain that the costs are standardised
An EPC compares homes on a level playing field: a standard household, standard heating hours and temperatures, and fuel prices from when it was lodged. Say plainly that the running costs aren't a forecast of their own bills. This one sentence heads off most "but my bills are lower" calls.
3. Be open about what was assumed
Where you couldn't see something, such as wall insulation, a floor or a loft, the software uses default values for the age of the home. Tell the customer which parts were assumed, and that paperwork (installer certificates, building control sign-off, guarantees) can get the real thing counted next time.
4. Put the cheapest steps first
The recommendations are listed in a set order, but people act on cost. Point out the low-cost wins, like low-energy lighting or a hot water cylinder jacket, before the big-ticket items like solar panels or wall insulation.
5. For landlords, link it to the rules
Landlords mostly want to know whether the property meets the minimum standard for letting and what it would take to get there. Point them to the current minimum energy efficiency standards on GOV.UK rather than quoting dates from memory, as they change.
6. Mention help with costs, and a warning
Some households qualify for free or cheaper upgrades through government schemes. Send them to GOV.UK's free checker, and warn them about cold callers offering "free" work.
EPC Customer Report turns any EPC into a plain-English report for your customer, with your name and logo on it: the rating, each part of the home, what was assumed and what to do first. Free, no account, works on your phone.
Try it on a certificate
Certificates are valid for 10 years. The official certificate on the government register is always the legal document.
