Energy Performance Certificate required for all lettable properties

Since October 2008, your rental property has required an Energy Performance Certificate (EPC), renewable every ten years. The EPC gives information on how to make your home more energy efficient by looking at its current energy use and typical energy costs along with a recommendation report suggesting ways to reduce energy waste and save money.  

But is an EPC just another piece of expensive paperwork? Roy Williams of Oxford Energy Assessors believes not. ‘An EPC is often misunderstood as just another piece of red tape but it can actually be a useful tool in reducing bills. Money can also often be saved quite quickly by acting on suggestions made in the certificate' says Roy. 'Loft insulation, for example, can increase energy efficiency considerably, and often can be done for free with a grant from the Energy Savings Trust'.

The EPC works by detailing a ratings system which compares the current energy efficiency and estimated costs of energy use with potential figures that your home could achieve. Each rating measures the energy efficiency of your property using a grade ‘A’ (most efficient) to ‘G’ (least efficient) and is based on factors such as age, property layout, construction, heating, lighting and insulation. Information is also provided about eligibility for funding, such as through grants or with the new ‘Green Deal’ scheme. Launching in October 2012, this scheme allows for homeowners to make improvements on their property without having to pay up front but instead paying over time through their electricity bill, at a level no greater than the estimated savings to energy bills.

Your EPC must be carried out by an accredited Domestic Energy Assessor (DEA) so make sure to check the credentials of your contractor. Further details can be found at
