New to EPC in Llangefni?
Need an EPC before you advertise in Llangefni? Here’s what the assessor does, how long a visit takes, and how long the certificate usually lasts.
An Energy Performance Certificate rates how energy-efficient a home is on an A–G scale and lists recommended improvements. You’ll need a valid EPC when you market or let most rented homes. It’s not a “boiler MOT” — it’s a snapshot of the building’s fabric and fixed systems, produced by an accredited assessor.
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):
- 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.

GOV.UK selling a home — EPCs · GOV.UK find an energy certificate · EPC dwellings guide
- An EPC is generally needed when a home is built, sold or rented, and is generally valid for 10 years (or until a newer EPC is lodged).
- MEES: privately rented homes covered by the regulations generally need at least band E unless a valid exemption is registered. Since April 2020 this applies to continuing lets as well as new ones. Government has signalled interest in a longer-term path toward higher bands — check current policy; don’t assume a future C duty is already law.
Scotland
mygov.scot — when you need an EPC · Scottish EPC Register · gov.scot EPC guide
gov.scot EPC publications · mygov.scot EPC pages — do not invent a live PRS minimum band.
- Make a valid EPC available when letting to a new tenant (including many short-term lets). Check the Scottish EPC Register. Historically EPCs have been valid for 10 years.
- Minimum energy standards for private rented homes have been proposed / consulted on but are not simply “band E like England”. Scottish Government correspondence in 2026 indicated PRS minimum standards wait on EPC reform clarity. Separately, EPC reform (new ratings, shorter validity) has been planned — check live gov.scot / mygov.scot before marketing, especially around late 2026 commencement talk.
