Green Deal Assessors, Assessment and Advice

A green deal assessor will visit the home or business premises to assess the fabric and occupancy of the building. They will explain how the instalments will work and make sure the cost of any suggested improvements will be covered by the savings on the energy bills. They must also declare any commission they may earn from the assessment and they must also declare any links they may have to green deal providers.

Domestic property assessment

In the first instance, an assessment of the fabric of the building is carried out which is based on the same principles as when producing and energy performance certificate. The report will provide a set of recommendations which should improve the energy efficiency of the building.

If a building already has an EPC which was done recently, then, this assessment of the fabric may not be required. However, it is possible that any EPC provided before April 2012 will not be sufficient to prevent the assessment being carried out because the approved tool (RdSAP) has recently been updated with new recommendations including for example flat roof, room-in-roof insulation and floor insulation. Regional weather is also to be taken into account. As the assessment will be free, it doesn’t really matter whether any previous EPC is suitable for the purpose or not in all honesty.

Assessment of the occupancy of the building

The next step when assessing domestic properties is to consider the way householders occupy the building. This should take into consideration some of the main elements that can affect the actual energy use by the household, for example, the number of occupants, type of heating system, actual temperature the home is heated to, annual fuel bills and the reliability of heating equipment.

Assessment of non-domestic (business) premises

The assessment method for non-domestic buildings will build upon the existing Simplified Building Energy Model (SBEM) methodology for producing an EPC, taking into account the way the existing occupants use the building to produce estimated energy savings and recommendations. In addition to allowing the default EPC assumptions to be changed to better reflect actual building-use patterns, the new assessment will take into consideration energy management practices, fuel tariff information and historical energy consumption data, where available.
