As there are a vast array of different property types, each property type must be considered carefully before we can give you a quote due to the number of variables involved in assessment procedures.
For instance we have to consider the type of property, size in square meters or feet, number of storeys, if the premises is detached or adjoined, building age, average ceiling heights, wall and roof construction, wall and loft insulation, alternative wall construction, windows if double or single glazed including their age, heating system with the fuel type making a considerable difference to the rating. Also other variables such as the boiler type, types of lighting being used, hot water system, air conditioning and solar photovoltaic or solar thermal improvements.
All this information goes into calculating the energy rating of your Domestic building.
