Energy Performance Certificates (EPCs)
What every Canvey Island buyer and seller needs to know about EPCs
What is an EPC?
An Energy Performance Certificate (EPC) is a legal document that rates how energy-efficient a property is, on a scale from A (most efficient) to G (least efficient). It provides buyers and renters with a clear picture of likely energy costs and carbon emissions, and suggests improvements that could save money on bills.
EPCs are valid for 10 years from the date of issue and must be obtained before a property is marketed for sale or let.
How is an EPC assessed?
A qualified Domestic Energy Assessor (DEA) visits the property and inspects:
- The type, age and construction of the building
- Heating systems (boiler type, controls, hot water)
- Insulation (walls, roof, floors)
- Windows and glazing
- Renewable energy systems (solar panels, heat pumps, etc.)
The assessor uses this data to generate the EPC rating and a list of recommended improvements with estimated costs and savings.
Who is responsible for getting the EPC?
When selling a property, the seller is responsible for obtaining the EPC before the property is listed. When letting a property, the landlord must provide the EPC to prospective tenants before they sign a lease.
At Richard Poyntz, we can arrange an EPC assessment for you through our network of accredited assessors. Simply get in touch and we will organise it as part of getting your property to market.

How to improve your EPC rating
Insulation
Loft insulation and cavity wall insulation are among the cheapest, highest-impact improvements. They can move a rating up by a full grade in many cases.
Boiler upgrade
Replacing an old boiler with a modern A-rated condensing boiler — or a heat pump — can make a significant difference to your rating and energy bills.
Double glazing & solar
Upgrading to double or triple glazing reduces heat loss. Solar panels can boost your rating and significantly cut electricity costs.
Does a better EPC rating help sell your home?
Yes — increasingly so. With rising energy costs, buyers are paying more attention to running costs. A property with a C or B rating is a genuine selling point compared to a D or E-rated neighbour. Some mortgage lenders also offer preferential "green mortgage" rates for energy-efficient homes, which can help buyers afford a higher purchase price.
