Much like the multi-coloured sticker on new appliances, the Energy Performance Certificates (EPCs) tell you how energy efficient a building is and give it a rating from A (very efficient) to G (inefficient). They let the person using the building know how costly it is likely to be to heat and power, and what carbon dioxide emissions there will be. Once produced, EPCs are valid for ten years. The EPC will also state what the energy efficiency rating could be if improvements are made, and highlights cost-effective ways to achieve a better rating.
Documentation related to this area of renewable energy is expansive therefore the following links may help you in your research. Alternatively we can visit you and explain all the details in your home and advise you as to the best course to take. For instance, in some cases of renewable energy installations planning permission is required. We will undertake this on your behalf, which will remove much of the hassle the paperwork side can be.
In order to qualify for the Government’s Feed In Tariff at the standard rate for PV Solar Installed systems, your property or building needs to have an Energy Perfomance Certificate rating of Band D or above. If your property or building does not reach that level of certification, then you will need to carry out energy efficient improvements, such as cavity wall insulation or loft insulation, before you can apply to be a part of this scheme. Alternatively you can receive the Feed In Tariff at the lower rate of 9p/kWh for the lifetime of the tariff which is currently 20 years.
These new rules were introduced by the Government in April 2012 in order to ensure that homes meet minimum standards of energy efficiency before it encourages the installation of Solar PV. They also only apply to new solar PV installations and extensions to existing Solar PV systems from 1st April 2012.
