A straightforward, expert answer to epc cost, written by accredited energy assessors — with the facts you need and clear next steps.
Epc cost is one of the questions we hear most often as accredited energy assessors. This guide gives you a clear, practical answer — what an EPC is, what it costs, what affects your rating, and how to get a fully-accredited certificate booked quickly.
The short answer
An Energy Performance Certificate (EPC) rates a property's energy efficiency from A (most efficient) to G and is a legal requirement whenever a property is sold or let. A domestic EPC typically starts from £60 and is valid for 10 years. With NextDay EPC you get next-day availability, a fixed price up front and no upfront payment — you pay on the appointment.
EPC cost: a quick breakdown
Domestic EPC pricing is based on the size of the property. Here's what to expect — every price is fixed, with no hidden fees, and includes lodging your certificate to the national register:
| Property size | Typical EPC price | Turnaround |
|---|---|---|
| 1 bedroom | £60 | Next-day available |
| 2–3 bedrooms | £80 | Next-day available |
| 4–5 bedrooms | £100 | Next-day available |
| 6+ bedrooms | On request | Next-day available |
Commercial and larger properties are quoted on enquiry. See our Domestic EPC pages for full details, or get an instant quote.
EPC ratings explained: A to G
Every EPC gives your property a score from 1–100 (the SAP score) which maps to a letter band. The higher the band, the lower the running costs — and for landlords, the band directly affects whether you can legally let the property:
| Band | SAP score | What it means |
|---|---|---|
| A | 92–100 | Excellent — very low energy bills |
| B | 81–91 | Very good — efficient modern home |
| C | 69–80 | Good — the target for landlords by 2030 |
| D | 55–68 | Average — most UK homes sit here |
| E | 39–54 | Below par — current legal minimum to let |
| F–G | 1–38 | Poor — cannot usually be let without works |
What affects your EPC rating the most
The biggest levers on any EPC are insulation, heating and how the property generates or uses energy. These are also the fastest routes to a better rating:
- Heating & hot water — efficient, low-carbon heating such as an air-source heat pump is one of the biggest single improvements, and can attract up to £7,500 through the Boiler Upgrade Scheme.
- Insulation — loft, cavity and wall insulation cut heat loss and lift your score cheaply.
- On-site generation — solar & battery adds renewable generation the EPC calculation directly credits.
- Lighting & controls — LED lighting and smart heating controls give small, low-cost gains.
- Glazing & doors — double or triple glazing reduces heat loss through windows.
How the assessment works
An accredited assessor visits the property and records its construction, insulation, heating, hot water, lighting and any renewables. The visit for a typical home takes 30–60 minutes. We then produce your certificate and lodge it to the national EPC register, usually the same or next day. You'll receive both your rating and a list of recommended improvements with their likely impact.
