Domestic Energy Assessors in Surrey

A standard inspection typically takes between 45 and 90 minutes depending on the size and complexity of the property. The assessor needs to access every room, the loft, and the heating system to record necessary data. Large homes with multiple extensions or complex layouts may require additional time for accurate measurements. Following the site visit, the professional processes the data through specialised software to produce the final certificate. This administrative phase usually completes within 24 hours of the physical survey being finished.

Property owners should provide evidence of any energy-saving improvements like double glazing, wall insulation, or boiler replacements. Having these certificates or invoices available allows the surveyor to enter the exact specifications into the system rather than using default values based on the building's age. If a property has solar panels, documentation regarding their capacity and installation date is particularly helpful. Clear access to the gas and electricity meters, as well as the water cylinder if present, is also required for a thorough survey.

A property cannot fail an assessment in the traditional sense, but it may receive a lower rating than expected. The survey provides a grade from A to G, reflecting the current efficiency level and suggesting potential improvements. However, for rental properties, there are legal minimum standards that must be met before a new tenancy can begin. If a rating falls below the required threshold, the report will outline specific actions needed to reach compliance. These recommendations might include upgrading insulation or installing more efficient heating controls.

Yes, new builds require a Predicted Energy Assessment (PEA) followed by an On Construction EPC. These are based on the design specifications and building materials used during the construction process rather than a physical survey of an existing inhabited home. The developer is responsible for ensuring these certificates are in place before the property is sold or occupied for the first time. For existing homes being renovated, a standard domestic assessment is usually sufficient once the works are completed to reflect the new efficiency profile of the building.
