What the assessor records
The assessor carries out a non-invasive visit and records features that impact heat loss and heating efficiency.
- 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
Typical timing
EPCs are designed to be straightforward—assessment and delivery are usually within a short window.
- On-site visit: commonly 20–60 minutes (size dependent)
- Certificate delivery: often same day to 48 hours (provider dependent)
Cost notes
Fees depend on floor area, property type, and access arrangements. Many providers offer fixed fees for standard homes; larger or more complex properties can cost more. Add your local fee range or quote form to this page.
What drives the rating
- 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
Ways to improve
To lift the rating, start with quick wins and then plan larger upgrades over time:
- Fit LED lighting throughout
- Improve loft insulation first (often the quickest win)
- Upgrade heating controls (programmer/thermostat/TRVs)
- Service or replace older heating systems over time
- Improve seals and reduce drafts
- Explore renewables where feasible
Landlord checklist
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 Islington FAQs’
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.
Do flats and houses get assessed differently?
The method is the same, but heat-loss assumptions can differ due to shared walls and communal areas.
Do I need an EPC for a new build?
Yes. New builds receive an EPC on completion, usually coordinated by the developer.
How long is an EPC valid for?
EPCs are typically valid for 10 years from the issue date.
Can landlords use an old EPC?
Only if it’s still valid. If major upgrades were done, renewing can better reflect the current performance.
Can I improve my rating after upgrades?
Yes. After improvements (insulation/heating), you can order a new EPC to reflect the changes.
Do I need documents to prove upgrades?
Not always, but evidence (boiler certificates, insulation receipts) can help record features accurately.
Is an EPC the same as a building survey?
No. An EPC focuses on energy efficiency, not structural condition or defects.
