What’s involved

• An accredited domestic energy assessor visits, measures, and records walls, floors, roof, windows, heating, controls, lighting and so on.
• They lodge the certificate on the official register. You get a digital EPC with a rating and a recommendations list.
• Adverts should show the rating where required. Prospective tenants should be able to see the certificate; the person who becomes the tenant gets it free of charge.
• The recommendations table is your shopping list for improvements — useful for MEES (minimum standards) in England and Wales, and for comfort and bills everywhere.
• Never guarantee a band. Improvements can help a rating; they don’t promise a letter until a new assessment is lodged.

How long a typical visit takes

• Often 30–60 minutes for a typical flat or small terraced house.
• Often 45–90 minutes for a larger house, complex heating, loft conversions, or hard-to-measure extensions.
• The assessor needs access to the loft hatch, heating controls, boiler, and all rooms — empty cupboards help more than you’d think.
• Lodgement is usually same day or shortly after; you can check the register once it’s live.

What the landlord must have ready

• Full access (or tenant agreed access) including loft, boiler cupboard, and meters.
• Age/type of extensions or conversions if you know them; any previous EPC reference number.
• Heating fuel type (mains gas, oil, LPG, electric, heat pump) — especially important in off-grid towns.
• Confirmation whether the property is being marketed to let (you generally need a valid EPC before marketing).
• In Scotland, note display / provision rules differ slightly — check mygov.scot / gov.scot.

Tips to prepare

Cheap or easy wins that often help an assessment (no band promised):

MEES landlord guidance

• Fit LED bulbs in landlord-supplied fittings before the visit.
• Add or top up hot-water cylinder insulation if you have a tank (cheap jacket).
• Fix obvious draughts around loft hatches and unused chimneys (appropriate caps / blockers — don’t block required ventilation for fuel appliances).
• Make sure heating controls work and are accessible (room thermostat, TRVs, programmer).
• Clear the loft so insulation depth can be seen and measured.
• After improvements that matter (insulation, boiler, glazing, heat pump), commission a new EPC if you need the register to show a better rating for MEES or marketing.
• For England & Wales MEES: if you’re below E, read the official landlord guidance on the £3,500 cost cap and exemptions register before you spend.
