Domestic Energy Assessment & Non Domestic Energy Assessment Services in London
Domestic Energy Assessment (DEAs)
Domestic Energy Assessors (DEAs) will assess the energy efficiency of existing residential buildings (houses, bungalows and flats) in the UK. Their work is completed on site and is considered to be non-invasive (no drilling into walls required).
A domestic energy assessment can take anywhere between 30 minutes and a few hours, depending on the property size and complexity, and will involve the collection of property information (such as property age, type of windows, type of heating systems, insulation etc), alongside photographic evidence and a floor plan.
This information will be collected and calculated within specialist software (RdSAP), which will provide an energy efficiency rating and produce an Energy Performance Certificate (EPC).
Non Domestice Engery Assessors (DEAs)
Non Domestic Energy Assessors (NDEAs) are qualified to assess the energy efficiency of non-domestic/commercial buildings. Depending on the level of qualification held, an NDEA can assess anything from a restaurant to an office building in Canary Wharf.
An NDEA’s role will require them to carry out an onsite inspection of a building. During this inspection they will collect information such as building age, number of floors, heating, ventilation and air conditioning (HVAC), size of rooms etc. The assessment itself is non-invasive which means you won’t be drilling into any walls.
Once the initial site assessment is completed, NDEAs can then use specialist online/desktop software to calculate the energy performance of the property and produce a legally valid Commercial Energy Performance Certificate (EPC). NDEAs may also be expected to explain their findings to property owners, and advise them on ways to improve their energy efficiency.
