EPC/Green Deal Reports

Energy Performance Certificates

Why do I need an EPC?

EPC’s are legally required whenever a property is built, sold or rented. You must order an EPC for potential buyers and tenants before you market your property to sell or rent.

An EPC is also required for Solar PV installations for feed-in-tariff applications as the household needs to achieve a grade D or above to obtain the highest tariff payments. For all installations provided by Sustainable Energy the cost of the EPC is included in the solar quotation. An EPC is also required as part of the Green Deal Advice Report, to claim payments under the Renewable Heat Incentive.

How much will it cost?

As well as installing various renewable energy sources, Sustainable Energy also produce Energy Performance Certificates (EPC’s) which are priced from £50 inclusive.

What does an EPC contain?

An EPC contains:

  • information about a property’s energy use and typical energy costs
  • recommendations about how to reduce energy use and save money

An EPC gives a property an energy efficiency rating from A (most efficient) to G (least efficient) and is valid for 10 years unless any energy improvements are implemented. The EPC rates a building’s performance in terms of:

  • Energy use per square metre of floor area,
  • Energy efficiency based on fuel costs
  • Environmental impact based on carbon dioxide (CO2) emissions


The EPC provides a list of things the property owner can do to improve energy efficiency. It outlines the typical savings per year and the potential performance ratings after the improvements have been made. The improvements are divided into ‘lower cost measures’ of up to £500 and ‘higher cost measures’ for larger amounts.


Green Deal Advice Report

How can I get a Green Deal Advice Report?

Sustainable Energy offer competitive prices on Green Deal Advice Reports (GDAR) which are produced by in-house, qualified assessors.

A GDAR consists of 2 documents:-

  • An Energy Performance Certificate (EPC) (Enter a link to an example pdf)
    This certificate provides an energy rating for your home on a A-G scale.
  • Occupancy Assessment (OA) (Enter a link to an example pdf)
    The certificate assesses how you use energy in home.

Only a Green Deal Assessor can produce a GDAR and we have in-house assessors to provide reports which are require for all claims for Domestic Renewable Heat Incentive (RHI) claims.
