An Annual Home Energy Check

An annual home energy check is a single, unhurried walk through the home once a year, looking at fabric, heating, ventilation, controls and records, and writing down what is found. Its value is not in any single observation, but in comparison: this year's readings against last year's, this year's draughts against last year's, this year's service status against the calendar. A check done at the same time each year, in the same order, with the same note, turns vague impressions into a trend, and a trend is what distinguishes a developing problem from a passing quirk. This guide sets out the walk, the record and the professional bookings that belong with it. It covers observation only for safety-critical systems, which must be inspected by qualified professionals.

The annual walk covers six areas in order. Fabric: walls, windows, doors, loft access where safe, and any visible damp, staining or draughts, including extensions and flat roofs where observable. Heating: system service status, radiator function, thermostat and programmer understanding, and any unusual noises, leaks or error displays to report, not to repair. Ventilation: trickle vents, extract fans, chimneys and any blocked routes, plus condensation or mould signs. Controls: every control operated and understood, with settings noted. Records: certificate currency, warranties, service dates and meter readings. Occupancy: any change in household size, room use or working patterns that explains a change in energy use. Each area gets a line in the note, even when the line reads no change, because no change is itself information.

Prepare the check with the previous year's note, the certificate, service records and a meter-reading method, then walk the home room by room at a consistent time of year, ideally before the heating season. Note readings, settings and observations with dates, and photograph anything that has changed. Book professional work from the check, rather than during it: heating service, electrical or gas safety checks, ventilation repairs and any specialist survey, each with a qualified professional. Compare energy use with the previous year, allowing for weather and occupancy, and note explanations for large changes. File the note with the home's energy records, and diary any follow-up with a date. A check without a filed note and a follow-up date is a walk, not a check.

Annual check expectations sit alongside national inspection and safety regimes. In the UK, heating servicing, gas and electrical safety checks, EPC validity and landlord safety duties each follow national timetables, with distinct arrangements across the nations. In EU member states, heating and air-conditioning inspection duties, certificate validity and maintenance expectations are national under the EPBD framework. The annual walk itself is portable: fabric, heating observation, ventilation, controls, records and occupancy, in the same order each year. The professional inspections and safety checks that the walk books are national, and a reader should confirm their timetable for the country where the home stands, rather than assuming a schedule from another jurisdiction.

The most common annual-check mistake is doing it only when something breaks, which converts a preventive routine into a repair queue. Another is checking in summer alone, when heating defects hide and ventilation problems look different. A third is noting observations without readings, so year-on-year comparison is impossible. A fourth is attempting safety-critical inspection or repair during the walk, rather than booking a professional. A fifth is filing the note where nobody can find it, or never diary-ing the follow-ups, so the check's findings evaporate. The remedy for all five is routine discipline: same date, same order, same note, filed, with follow-ups dated. Boring consistency is the entire point of an annual check.

Keep annual notes as a series, so the home's energy history can be read at a glance, and share the current note with any professional who works on the home. When a retrofit is proposed, the series shows what has drifted, what has been maintained and what the home actually needs, which sharpens the brief considerably. When a move or tenancy change occurs, pass the latest note to the next occupant as part of the handover. A home with a series of annual notes is a home whose energy story is documented across years, and that documentation is worth more than any single year's observations, however careful they were.
