When our accredited assessor arrives at your property, they will perform a non-invasive visual inspection of the key elements that affect your building’s energy performance. This includes measuring the internal and external dimensions of the property, inspecting the heating system and controls, and identifying the type of insulation and glazing installed. We also take a series of evidentiary photographs of the boiler, meters, and insulation as required by government audit standards.
A typical domestic survey for a standard 3-bedroom semi-detached house usually takes between 45 and 60 minutes.
However, this timeframe is dependent on the size and complexity of the property; smaller apartments may take less time, while larger or older heritage homes with multiple extensions may require 90 minutes or more to ensure every detail is accurately captured.
To ensure you receive the most accurate rating possible, we recommend having the property ready for the assessor. If an element cannot be seen or evidenced, we are legally required to enter a “default” value, which is often significantly lower than the actual performance of the modern materials you may have installed.
Provide Access: Ensure the assessor can easily access the loft space, the hot water cylinder, and the heating controls (programmer and thermostats).
Documentation for Upgrades: If you have had cavity wall insulation, underfloor insulation, or internal wall insulation installed, please have the guarantee or installation certificate ready. Without physical or documentary evidence, these cannot be included.
Window & Door Data: For modern double or triple glazing, having the FENSA certificates or invoices showing the installation date helps us accurately date the thermal efficiency of the glass.
Renewables & Extensions: If you have solar panels, heat pumps, or a recent extension, please have any commissioning certificates or building control completion certificates available for inspection.
Clear the Path: Ensure all windows can be opened easily and that the boiler/cylinder cupboard isn’t blocked by storage, as the assessor needs to read the data plates on the equipment.
