EPC (Energy Performance Certificate)

Measuring energy efficiency and improving the use of energy is becoming increasingly important for all businesses. This is no different in the real estate business. Regulations regarding energy efficiency for buildings is also becoming more stringent as well.  As of April 2018, all residential and commercial properties that are rented out to tenants must have an Energy Performance Certificate (EPC) and buildings that have low ratings will be illegal to let.

Introduced by the UK Government in 2007, the EPC is a standardised document which rates the energy efficiency of a building and its environmental impact. The level of a building’s energy efficiency is rated using an alphabetic scale, with A being very efficient and G being most inefficient. A building with an E or F rating cannot be let. An EPC will also include detailed information about the building’s ongoing energy costs, as well as recommendations on how to improve the building’s energy efficiency. Improvements to energy efficiency will make a property more attractive to a potential buyer or tenant.

Ashworth Group will prepare your EPC Report by having one of our qualified property assessors visit your property. They will do a walk through the building and examine the insulation, the HVAC (Heating, Ventilation and Air Conditioning) system, the windows, the boiler, and so forth. This is a visual survey and will not require any special preparation by the landlord or tenant. This information, combined with additional building details, such as year of construction, type of building, is inputted into a simulation software that calculates the energy efficiency rating.

The EPC Report will also include suggested improvements that can be made, an estimated cost of such improvements and the estimated savings on utility bills, as well as how these improvements could change the rating of the property in the future. The EPC is valid for 10 years.

An EPC is always accompanied by a recommendation report that lists cost effective measures to help improve the energy rating of the building. The potential rating shown on the certificate is based on all the cost effective recommendations being implemented.

The recommendation report lists:

  • Suggested improvements and recommendations. (Such as fitting loft insulation)
  • The approximate cost of these recommendations.
  • Possible cost savings per year if the improvements are made.
  • How this would change the energy and carbon emission rating of the property.

You can use this information to:

  • Cut your fuel bills.
  • Improve energy performance in your home.
  • Help cut carbon emissions.
  • Help you choose a more energy efficient home to rent or buy.   

EPC's carry ratings that compare the current energy efficiency and carbon dioxide emissions with potential figures that your home could achieve. Potential figures are calculated by estimating what the energy efficiency and carbon dioxide emissions would be if energy saving measures were put in place.

The rating measures the energy and carbon emission efficiency of your home using a grade from A to G. An A rating is the most efficient, while G is the least efficient. The average efficiency grade to date is D.

EPC's are produced using standard methods with standard assumptions about energy usage so that the energy efficiency of one building can easily be compared with another building of the same type. This allows prospective buyers, tenants, owners, occupiers and purchasers to see information on the energy efficiency and carbon dioxide emissions from their building so they can consider energy efficiency and fuel costs as part of their investment.

You do not have to act on the recommendations contained in the report. However, if you decide to do so, then it could make your property more attractive for sale or rent by making it more energy efficient.
