Check Your EPC Rating

What Is an EPC?

An Energy Performance Certificate (EPC) rates the energy efficiency of a property on a scale from A (most efficient) to G (least efficient). It includes estimated energy costs, a breakdown of how the building performs, and recommendations for improvements that could reduce energy use.

In England and Wales, an EPC is a legal requirement when selling or renting a property. The certificate must be commissioned before marketing begins, and it must be made available to prospective buyers. EPCs are valid for 10 years from the date of assessment.

Why Your EPC Matters When Selling

Your EPC rating can influence how quickly your property sells and the price buyers are willing to pay. Research shows that energy-efficient homes sell for more, and buyers are increasingly factoring running costs into their decisions.

• Buyer confidence: A good rating (A–C) signals lower running costs and fewer potential issues with insulation, heating, or glazing.
• Mortgage implications: Some lenders offer better rates for energy-efficient properties, and minimum standards may tighten in future.
• Negotiation leverage: A poor rating (E–G) can lead to lower offers, as buyers price in the cost of improvements.
• Legal compliance: You cannot legally market your property without a valid EPC.

How to Improve Your EPC Rating

If your rating is lower than you'd like, there are practical steps you can take before listing. Some improvements are relatively low-cost and can move your property up one or two bands:

• Loft insulation: One of the cheapest and most effective improvements. Topping up to 270mm can make a noticeable difference.
• Cavity wall insulation: If your property has unfilled cavities, this is typically a cost-effective upgrade. Make sure you get a cavity wall insulation guarantee.
• LED lighting: Replacing old bulbs with LEDs throughout the property is cheap and contributes to the EPC score.
• Boiler upgrade: If your boiler is old and inefficient, a new condensing boiler can significantly improve your rating. Keep your boiler service records ready for buyers.
• Double glazing: Replacing single-glazed windows improves both the rating and buyer perception. Ensure you have a FENSA certificate for any replacement windows.

EPC and the Selling Process

Your EPC is one of several documents you need to sell a house. Beyond the EPC, you will need to complete property information forms (TA6, TA10), order property searches, and gather various certificates. Getting all of this ready before listing can speed up your conveyancing by weeks.
