If your home feels cold, your bills are climbing, or you’re preparing to sell or rent, an outdated EPC could be holding you back. Many properties quietly slip below efficiency standards without obvious warning signs — which can lead to lower EPC bands, compliance issues for landlords, and reduced market value.

Here are the clear signs your home needs an EPC upgrade, plus what you can do before booking an assessment.

1. Rising Energy Bills With No Clear Reason

If your bills keep increasing despite normal usage, your home may be losing heat faster than you realise.

Common causes include:

  • Ageing insulation

  • Draughty windows

  • Inefficient boilers

  • Poor heating controls

A fresh EPC identifies exactly where the energy is being wasted.

2. Your EPC Is 10+ Years Old

EPCs expire every 10 years — but most homes change dramatically in that time.

You need an updated EPC if you have:

  • Renovated or extended your property

  • Changed heating systems

  • Upgraded insulation or glazing

Even small upgrades can boost your EPC band, but only if they’re reassessed.

3. Your Home Feels Cold or Draughty

If your home feels colder than it should, that’s a clear sign your energy efficiency is failing.

Possible issues:

  • Sub-standard loft insulation

  • Gaps around doors

  • Poorly performing double glazing

  • Uninsulated floors

These problems heavily impact EPC ratings.

4. You Have an Old Boiler or No Heating Controls

Even a well-maintained home can score poorly if heating systems are outdated.

Warning signs include:

  • A boiler older than 15–20 years

  • No room thermostats

  • No TRVs (thermostatic radiator valves)

  • No programmable heating schedule

Heating controls alone can boost an EPC rating by an entire band.

5. You’re Preparing to Sell or Rent

If you’re selling or letting a property, an outdated EPC is a serious disadvantage — and for landlords, potentially a compliance issue.

A new EPC helps:

  • Increase buyer confidence

  • Attract better tenants

  • Meet minimum EPC standards

  • Identify quick efficiency improvements

6. You’ve Noticed Condensation, Damp or Mould

Moisture problems often appear when the home isn’t ventilated or insulated correctly.

Assessors see this as a major efficiency failure caused by:

  • Poor airflow

  • Heat escaping through walls

  • Inadequate extraction in kitchens/bathrooms

These issues reduce thermal performance and decrease your EPC score.

7. Your Lighting System Is Outdated

If your home still uses halogen or incandescent bulbs, you’re losing energy — and EPC points.

Modern LED lighting improves:

  • Efficiency

  • Longevity

  • Overall EPC scores

This is one of the fastest, cheapest EPC improvements.

8. You Can’t Find Paperwork for Past Upgrades

Missing documentation is one of the biggest hidden EPC killers.

Without written proof of:

  • Loft insulation

  • Wall insulation

  • Boiler installation

  • Window upgrades

  • Renovation work

…your assessor must assume the lowest possible efficiency, even if the upgrade exists.
