Getting to know Caerphilly
Caerphilly is in the Caerphilly council area, Wales. On the council's ward map it takes in Penyrheol, St Martins, Morgan Jones, Van and Llanbradach wards.
Postcode-wise, Caerphilly sits in 1 district: CF83 (Abertridwr, Senghenydd, Bedwas and Trethomas), about 22,798 households (2011 Census households, via Doogal). The same district also takes in Aber Valley, Bedwas, Trethomas and Machen, Llanbradach and Pwllypant, Penyrheol, Trecenydd and Energlyn, Rhiwbina, Rudry, Taffs Well, Tongwynlais and Van, so an EPC assessor covering Caerphilly will often know those streets too.
Next-door postcode districts: CF82 (Hengoed); CF14 (Whitchurch); CF15 (Pentyrch); NP12 (Blackwood); CF5 (Ely); CF37 (Pontypridd).
Ward by ward, Caerphilly isn't all the same. Of its 4 main wards, private renting is highest in St Martins (13% of households) and lowest in Penyrheol (10%). For detached homes, St Martins leads (30%) and Van has the fewest (13%). (ONS Census 2021, output areas summed to 2025 wards inside the town.)
Want more choice? The nearest bigger towns are Cardiff (~6 miles south) and Newport, Wales (~10 miles east), and accredited domestic energy assessors based there may travel.
How old are the homes? Council tax records put 14% of Caerphilly's homes before 1919 and 15% since 2000 (Wales: 30% and 15%), so the housing here is close to the Wales average. The biggest slice was built between 1973 and 1999 (36%). Newer homes usually start from a better EPC rating, but check the certificate is still valid. (VOA council tax stock, 2025.)

New to EPC in Caerphilly?
Need an EPC before you advertise in Caerphilly? 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.
