What to expect

About the Report

The HI/DEA does not determine any of the ratings given. The ratings are derived from the information collected by the HI/DEA and input into the software. Nor do they have control over whether the elements are classified as; very poor, poor, average, good or very good. The report may state that there is partial double glazing even if the majority of windows are double glazed. The report will also state partial low energy lighting, again if the majority of light fittings are low energy light bulbs. The report makes certain assumptions beyond the HI/DEA control. For example, it assumes whether: a) floors are solid or suspended (and assumes the level of insulation (the HI/DEA cannot override this) b) if cavity walls have insulation when built c) the thickness of loft insulation if this cannot be inspected i.e., if a loft space is boarded or there is a limitation to inspect Loft insulation where a room in the roof is present is assumed to be the appropriate level at the time of construction The annual heating and lighting costs are not calculated by the HI/DEA but by the RdSAP (Reduced data Standard Assessment Procedure) conventions.

Conservatories are ignored if they are separated from the dwelling by external quality doors.  Analysis of the early phase of rollout of HIPs found that the average EPC rating for homes was E and a rating of 46.

What to expect when a Home Inspector (HI)/ Domestic Energy Assessor (DEA) visits the property

The HI/DEA will be taking measurements of the property, drawing floor plans and making site notes. It will be necessary to photograph some aspects of the property and appliances for the report’s site notes. Access is required to all rooms of the property to assess the methods of heating, lighting and ventilation in the home. Clear access is required to meter cupboards, heating systems and their controls, i.e., boilers, timers, hot water cylinders and thermostats etc. An inspection of the loft space (if accessible) is required to assess insulation. The HI/DEA will have his/her own ladders available. It might be necessary to open windows and doors to determine wall thickness. For the average 3 bedroom property the inspection will take approximately 1 hour – longer if the property is larger or of unusual complexity.
