- Building form (flat/terrace/semi/detached) and floor area
- Insulation indicators (loft, wall type)
- Heating and hot-water system plus controls
- Windows/doors (glazing)
- Lighting efficiency
- Renewables where applicable

- Insulation level (loft depth; cavity/solid wall suitability)
- Boiler efficiency and modern heating controls
- Glazing type and draft reduction
- Low-energy lighting coverage
- Renewables (solar PV, heat pumps) where present
Improve the score
To lift the rating, start with quick wins and then plan larger upgrades over time:
- Switch remaining bulbs to LED lighting
- Top up loft insulation where needed
- Add smart heating controls (thermostat/TRVs)
- Upgrade an inefficient boiler when due
- Draft-proof doors/windows
- Consider cavity wall insulation if suitable
Letting notes
Landlords should keep a valid EPC available for tenants and agents. EPCs are typically valid for 10 years, and re-issuing after upgrades can help reflect improvements and support letting compliance.
Reminder: Rental energy efficiency requirements can change—check the latest UK rules when letting a property.
EPC Certificate Cardiff FAQs’
Can I improve my rating after upgrades?
Yes. After improvements (insulation/heating), you can order a new EPC to reflect the changes.
What should I prepare before the assessor arrives?
Provide access to the boiler/heating controls, all rooms, and (if safe) the loft hatch. Keep upgrade evidence handy.
How long does the assessment take?
Many homes take around 20–60 minutes, depending on size and complexity.
Do I need an EPC before listing my property?
In most cases, yes—an EPC is required for marketing a property for sale or rent (with limited exemptions).
Do I need an EPC for a new build?
Yes. New builds receive an EPC on completion, usually coordinated by the developer.
Can an EPC be done without anyone at home?
Usually an adult needs to provide access. If you have a key-safe and permission, some assessors may accommodate, but it varies.
Do I need documents to prove upgrades?
Not always, but evidence (boiler certificates, insulation receipts) can help record features accurately.
Is an EPC required for short-term lets?
Rules can vary—if you’re unsure, check current guidance for your letting arrangement.
