Before the visit

A few things that help

None of these are essential, but if you can sort them ahead of time the assessment runs faster and your rating tends to be more accurate.

Gather documentation

Anything you can find for these helps us record accurate specs:

  • Boiler service records and manual
  • Window installation certificates
  • Insulation installation certificates
  • Solar panel documentation
  • Building control certificates
  • Previous EPC (if available)

Provide access

The assessor will need to see:

  • All rooms in the property
  • Loft space (if accessible)
  • Boiler and heating controls
  • Meter cupboard
  • External walls and windows
  • Roof space (where safe)

Clear access routes

Quick wins on the day:

  • Clear paths to all areas
  • Move furniture blocking radiators
  • Make sure the loft hatch is accessible
  • Have keys ready for locked rooms
  • Flag any hazards we should know about
  • Pop pets somewhere safe

Just so you know

What an EPC is not

An EPC is a measure of energy efficiency — not a structural survey, a condition report, or a safety inspection. The assessor won't check:

Structural issues

No checks for defects, damp, subsidence or building condition.

Appliances

Washing machines, ovens and fridges aren't part of the assessment.

Electrical safety

The EPC doesn't include electrical safety testing or wiring checks.

Gas safety

Gas safety certificates and boiler servicing are separate jobs.

Maintenance

General property maintenance and repair needs aren't covered.

Property value

An EPC doesn't assess or affect property value or market price.

After the visit

From visit to certificate in four steps

  1. Certificate production

    We process the data and produce your EPC — usually within 24–48 hours.

  2. Invoice sent

    You'll get an emailed invoice with secure payment options.

  3. Certificate released

    Once payment lands, your EPC is released to you digitally.

  4. Lodged on the register

    The certificate is automatically registered on the government EPC register.

Pro tips

Get the best rating you can

Have documentation ready

Boiler manuals, window certificates and insulation records let us record accurate product specifications instead of falling back on defaults.

Complete improvements first

If you're planning upgrades, get them done before the assessment so they count towards your rating.

Point out recent upgrades

Tell us about new boilers, insulation, solar panels or anything else you've added.

Bring installation certificates

Official certs unlock product-specific data — usually better than the conservative defaults.
