The EER shows the energy efficiency of your home – the higher the rating, the lower the running costs.
The EIR is a measure of the home’s effect on the environment in terms of carbon dioxide emissions, one of the biggest contributors to global warming. The higher the rating the less impact it has on the environment.
The average property in the UK is currently in Band D for both the Energy Efficiency Rating and the Energy Impact Rating.
By law an EPC must be carried out within 28 days of marketing your property by an accredited Domestic Energy Assessor. As EPCs are valid for a duration of 10 years it may be that your property already has one, you can check this on the EPC register online.
As of 1st April 2018 all properties with a new lease starting after this date must have a minimum EPC rating of ‘E.’
Your EPC will suggest ways in which you can improve the efficiency of your home. Here are some common suggestions:
Switch to low energy lighting for all fixed outlets
Replace single glazed windows with Low-E double glazed windows
Increase loft insulation
Replace boiler with a new condensing boiler
Internal or external wall insulation
Solar Water heating
