EPC Service Guide

During a domestic EPC survey, the assessor records key property details such as construction type, insulation, heating system, hot water system, windows, lighting and renewable energy features where present. The assessor may also take measurements and photographs as evidence for the EPC record.

Most domestic EPC assessments take around 30–45 minutes on site. Larger homes, HMOs, unusual layouts or properties with extensions may take longer.

It helps to provide access to all rooms, heating controls, the hot water cylinder if present, safe loft access where available, and any documents for insulation, extensions, double glazing or renewable energy installations.

Where possible, HomeNRG lodges the EPC certificate on the same day after the property assessment. The certificate is then available through the official EPC register.

In most cases, a valid EPC is needed when a domestic property is marketed for sale. The EPC shows the property’s energy-efficiency rating and recommended improvements.

In most cases, landlords need a valid EPC before marketing or letting a domestic rental property. If the EPC has expired or no certificate exists, a new EPC assessment should be arranged.

If the existing EPC is still valid, it can usually be used. If the EPC has expired before a new tenancy is granted, the landlord should arrange a new EPC before letting the property.

An EPC is normally valid for 10 years unless a newer EPC is lodged for the same property. If substantial energy-related improvements have been made, a new EPC may give a more up-to-date rating.

A valid EPC can normally be used while it remains in date. If it has expired before a new tenancy starts, the landlord should arrange a new EPC assessment before the property is let.

An EPC assessor is a trained and accredited energy assessor who inspects a property and lodges an Energy Performance Certificate through an approved accreditation scheme.

HomeNRG is operated by an Elmhurst-accredited Domestic Energy Assessor. Assessor details can be checked before booking using official assessor services.

HomeNRG provides domestic EPC certificates for flats, houses, maisonettes, rental properties, homeowners, landlords, letting agents and property managers. Commercial EPCs require a non-domestic energy assessor.

HomeNRG is based in Enfield and covers North London, parts of East London, nearby Essex areas and surrounding locations including Cheshunt, Waltham Cross, Edmonton, Chingford, Walthamstow, Tottenham, Barnet, Palmers Green and Winchmore Hill.
