Domestic EPC

What is an Energy Performance Certificate (EPC)?

An EPC is simply a certificate that provides you with a rating which reflects the energy efficiency of your property.

The EPC is valid for 10 years.

What does an EPC assessment involve?

EPC Efficient will provide you with a quick and professional service which will take on average 30 minutes to complete. (time will vary depending on the property size). In this time we will examine key items in your property such as windows, lighting, heating system and all types of insulation. After we have examined the necessary items the observations will then be recorded into the system which performs the calculation of the property’s energy efficiency.

Once this is completed the system will generate the EPC which will provide you with a rating from A (very energy efficient) to G (not energy efficient). The system will also inform you with a potential rating and will list any recommendations on improvements to the property which will help to achieve the potential rating.

When is an EPC required by law?

Energy Performance Certificates (EPCs) are needed whenever a property is:
Built, Sold or Rented. This is a key piece of Legislation which requires assessment of energy rating of domestic properties.

You must order an EPC for potential buyers and tenants before you market your property to sell or rent.
EPC assessment is also called RdSAP assessment. RdSAP (Reduced Data Standard Assessment Procedure)

When is an EPC required other than legal requirements?

An EPC is also required for:


  1. Green Deal Finance Scheme – The Green Deal is a scheme for finance / loan designed to help homeowners and landlords invest in renewable energy or energy efficient products, by providing them with attractive finance which they repay through their electricity bills.
  2. Feed in Tariff Scheme – (The Feed-in Tariffs (FIT) scheme is a government program designed to promote the uptake of renewable and low-carbon electricity generation technologies i.e. Solar PV Panel, Wind Turbine etc.)
  3. RHI Scheme (Renewable Heat Incentive) – The Domestic Renewable Heat Incentive (Domestic RHI) is a government financial incentive to promote the use of renewable heat using technologies such as Biomass Boilers, Heat Pumps or Solar thermal panels.
  4. ECO (Energy Company Obligation) – The ECO scheme means that large gas and electricity suppliers – including British Gas, EDF Energy, Eon, Npower, Scottish Power and SSE – are obliged to help households with energy-efficiency measures. This will help save people money on their energy bills, keep homes warmer by offering free home insulation’s, free heating systems etc.


Changing your lights (light bulbs) over to energy efficient versions can improve your score by more than you think!
