Energy Assessors UK — the Right Assessor, First Time
Four different assessor qualifications cover UK property, and booking the wrong one wastes your fee. Tell us the property and the purpose; we match an accredited local assessor and a fixed price within one working day.
Four assessor types, one booking point
UK energy assessment is split by qualification, and the splits matter — each certificate type can only be produced by the matching accreditation.
Domestic Energy Assessors
DEAs survey homes under RdSAP for sale and rental EPCs. The workhorse qualification — and the one reshaped by the RdSAP 10 update.
Non-Domestic Assessors
Levels 3, 4 and 5 for commercial buildings of rising complexity, from corner shops to atrium HQs. Details on the commercial page.
Retrofit Assessors
PAS 2035 retrofit assessments for grant-funded and whole-house upgrade work — the gateway document for most insulation and heat pump funding.
TM44 Inspectors
Statutory air-conditioning inspections for systems over 12 kW — a separate accreditation again, required every five years on commercial cooling.
Not sure which applies? The find-an-assessor guide walks through it in two minutes.
How the matching service works
We are not a call centre reselling leads to whoever pays most. The service is narrower and more useful: verify what you actually need, match it to an accredited assessor working your postcode, and fix the price before anyone books anything.
- 1You describe the property and the purpose. Selling a flat, letting a shop, applying for grant funding — purpose decides the assessment type, and we correct mismatches at this stage, free.
- 2We verify and match. Every assessor we use is checked against the official accreditation registers — name, number, qualification level, current status.
- 3You get a fixed price and a date. Within one working day. Domestic surveys typically happen inside the week; certificates usually lodge within 48 hours of survey.
Costs are published openly on the EPC cost page — including what makes a quote suspiciously cheap.
What is changing in 2026 — and what is not
Energy assessment is in its biggest period of change since EPCs launched in 2007, and a lot of what circulates about it is wrong. The short version, regularly updated across this site:
- RdSAP 10 is live. Domestic assessments now collect far more measured data — the full guide covers what surveys now involve and why some bands shift on re-assessment.
- MEES still means EPC E for rentals. Proposals to require C for domestic lets — and C by 2027 / B by 2030 for commercial — remain proposals, not law. Plan for them; do not be panicked into believing they already apply.
- 0% VAT on energy-saving materials runs until March 2027 for domestic installations — insulation, heat pumps, solar — which changes the economics of acting on your certificate's recommendations now rather than later.
- EPC reform is coming. Government has consulted on broader EPC metrics (fabric, heating system, smart readiness rather than a single cost-based score). Nothing is in force yet; certificates issued today remain valid for ten years.
Before any assessment, the preparation guide lists the documents and small fixes that genuinely move a rating; the assessment walkthrough covers what the assessor will do on the day.
Coverage across the UK
The assessor network spans England, Wales and Scotland — cities, market towns and rural postcodes alike. Scotland's EPC framework differs in detail (certificates are lodged on the Scottish register and displayed differently), and Northern Ireland runs its own register; the matching service handles all of them, routing your booking to an assessor accredited for the right jurisdiction.
Urban bookings usually survey within two to four working days. Rural and island postcodes take longer — we will tell you the realistic date up front rather than promise one we cannot hold. For multi-property instructions — landlord portfolios, estate agents, block managers — one schedule gets one quote with per-property rates that fall as the count rises.
Timing tip for anyone planning improvement work off the back of a certificate: the 0% VAT rate on domestic energy-saving materials — insulation, heat pumps, solar panels and more — runs until March 2027. Acting on the recommendations while that window is open takes a meaningful slice off installed costs, and a re-assessment afterwards banks the improvement on the register where lenders and future buyers can see it.
The five situations that bring people here
- Selling a home. You need a valid EPC commissioned before marketing begins. First check the register — your existing certificate may still be in date. If it is old and your home has had work done, a fresh assessment under RdSAP 10 with the right documents often markets a band better than the stale one. Survey inside the week in most postcodes.
- Letting a property. MEES requires at least an E, and the practical questions are all about evidence: documented improvements bank points, undocumented ones do not. Landlords near the boundary get the straight answer before we book anything — sometimes the right move is paperwork plus a re-assessment rather than works.
- Taking or granting a commercial lease. Non-domestic certificates, Level 3–5 depending on the building, with the lease timetable usually the binding constraint. Simple units we match directly; complex buildings go to the specialists — see the commercial page for how that split works.
- Applying for grant funding or a green mortgage. Retrofit schemes need PAS 2035 assessments; lenders need current certificates. Both punish booking the wrong assessment type first, which is the mistake the matching step exists to catch.
- After renovating. New heating, insulation or solar deserves a certificate that reflects it — especially with RdSAP 10 now modelling low-carbon technology properly. Bring the installation paperwork; the preparation guide lists exactly what counts.
Questions people ask before booking
How do I find a legitimate energy assessor?
Every legitimate assessor in England, Wales and Northern Ireland is accredited through a government-approved scheme and appears on the public register at gov.uk — Scotland runs its own register. Check the name and accreditation number before booking anyone. Our matching service does that verification as standard, but the check is free and open to everyone.
What does an EPC cost in 2026?
Domestic EPCs typically cost £60–£120 depending on property size and region. Commercial certificates start around £250 for small simple units and rise with building complexity. Anyone quoting £35 for a four-bed house is making it up somewhere — usually on survey time, which is what the accuracy of your certificate depends on.
What is the difference between a DEA and a non-domestic assessor?
A Domestic Energy Assessor (DEA) surveys homes using RdSAP and can only certify dwellings. Non-domestic assessors qualify at Levels 3–5 for commercial buildings of increasing complexity. The accreditations are separate — a DEA cannot legally produce a commercial EPC, which is the single most common booking mistake we correct.
What changed with RdSAP 10?
RdSAP 10 — phased in from mid-2025 — is the biggest overhaul of domestic assessment methodology in a decade: more measured data instead of assumptions, address-level geolocation, better treatment of heat pumps, batteries and PV, and mandatory photographic evidence. Certificates produced under it are more accurate, surveys take a little longer, and some properties re-assess to a different band than their old certificate suggested.
Do I need an EPC before selling or letting?
Yes — in England and Wales you must have commissioned an EPC before marketing a property for sale or rent, and rented homes must meet at least EPC E under MEES rules. EPCs last ten years; check yours on the national register before assuming you need a new one, because around half the people who contact us already have a valid certificate.
