Need a better EPC rating but running short on time? The good news: even without major upgrades, small and strategic improvements can meaningfully enhance your home’s energy performance. These simple, last-minute tweaks help present your property at its most efficient — and they’re exactly the kind of details an EPC assessor notices during inspection.

If you haven’t scheduled your assessment yet, you can secure a slot instantly through our EPC Booking Page.

1. Upgrade to LED Lighting Throughout the Home

Lighting accounts for an easy but often overlooked part of the EPC score.

Quick win:

  • Replace all incandescent or halogen bulbs with LEDs

  • Ensure bulbs are installed and functioning in every room

  • Use warm or cool LEDs consistently for better presentation

LED lighting signals modern, low-energy usage — an instant score booster.

2. Stop Draughts at the Source

Draughty rooms suggest poor insulation and increased heat loss.

Try these fast fixes:

  • Add self-adhesive draught strips around windows and doors

  • Seal visible gaps with silicone

  • Use chimney balloons or covers to block unused fireplaces

Reducing heat leakage immediately signals improved thermal efficiency.

3. Reset Your Boiler to Efficient Levels

Your heating system heavily influences your EPC rating.

Simple pre-assessment steps:

  • Set boiler flow temperature to 55–60°C

  • Check pressure is in the green range

  • Enable eco mode

  • Ensure thermostats and TRVs work correctly

Even small adjustments show your heating system operates efficiently.

4. Bleed Radiators for Optimal Heat Output

Unevenly heated radiators can indirectly affect perceived efficiency.

Before the assessor arrives:

  • Bleed all radiators to remove trapped air

  • Ensure rooms heat evenly

  • Turn on the system to demonstrate smooth operation

A well-performing heating system leaves a strong impression.

5. Add Reflective Foil Behind Radiators

A low-cost improvement with surprisingly high impact.

Benefits:

  • Pushes heat back into the room

  • Reduces wall heat loss

  • Creates a more energy-efficient heating environment

Assessors recognise these as positive insulation enhancers.

6. Insulate Exposed Hot Water Pipes

Pipe insulation takes minutes but supports better hot water efficiency.

Quick action:

  • Fit foam tube insulation around exposed pipes

  • Check around boilers, hot water cylinders, or airing cupboards

This small upgrade can influence your domestic hot water efficiency rating.

7. Improve Loft Hatch Insulation

Even if your loft is insulated, a poorly sealed hatch can leak warmth.

Immediate fix:

  • Add insulation board on top of the hatch

  • Seal edges with draught tape

  • Ensure the hatch shuts tightly

A small detail that can help stabilise your insulation assessment.

8. Prepare Documentation for the Assessor

If you’ve made upgrades but cannot prove them, the assessor must record default (and lower) values.

Have ready:

  • Loft insulation depth confirmation

  • Cavity wall insulation certificates

  • Double glazing installation details

  • Boiler installation paperwork

  • Renewable tech documentation (e.g., solar PV)

9. Ensure Full Access to Key Areas

Assessors must inspect:

  • Bolier & heating systems

  • Hot water cylinders

  • Loft space

  • Meters

  • Heating controls

If anything is blocked or inaccessible, they must assume the lowest score.
Our EPC Assessor Services in London explain why.
