If your EPC inspection is just around the corner, don’t panic — there are still several fast, inexpensive improvements you can make to give your rating a helpful boost. These quick fixes won’t replace major upgrades, but they can instantly improve efficiency, reduce heat loss, and present your home in a better light during the assessment.
Before you start, you can confirm your EPC booking or schedule an urgent inspection through our Booking Page.
1. Seal Draughts Around Windows and Doors
Draughts are one of the first things an EPC assessor notices. Even small gaps can significantly affect thermal performance.
Quick Fixes
Add self-adhesive foam or rubber draught strips
Seal gaps using silicone
Close unused chimneys with a removable draught stopper
These low-cost changes instantly reduce heat leakage — a positive signal during your EPC inspection.
2. Install Basic LED Bulbs in All Rooms
Lighting is a simple EPC category, yet many properties lose points unnecessarily.
Before the assessor arrives:
Replace halogen and incandescent bulbs with LEDs
Ensure all bulbs are working
Use consistent LED lighting throughout the home
LEDs improve your energy efficiency rating and show that your home uses low-energy lighting systems.
3. Bleed Radiators for Better Heating Efficiency
Cold spots and inefficient radiators can suggest poor heating performance.
Do this the night before:
Use a radiator key to release trapped air
Ensure the heating system warms evenly
Check for rooms that stay unusually cold
A well-functioning system can support a stronger score under the heating efficiency component.
4. Adjust Your Boiler Settings
Your boiler contributes heavily to your EPC rating. Even without replacing it, you can optimise performance quickly.
Simple adjustments:
Set the flow temperature between 55–60°C
Ensure the boiler pressure is in the green zone
Enable eco mode if available
Set thermostats correctly
These changes indicate an efficiently operated heating system — something assessors take into account.
5. Add Reflective Panels Behind Radiators
Radiator reflector panels help push heat back into the room rather than letting it escape through walls.
Benefits
Cheap and easy to install
Reduces heat loss
Shows proactive heat-retention efforts
A positive detail your assessor will notice.
6. Lag Exposed Hot Water Pipes
If you have exposed pipes near the boiler or cylinder, insulating them helps prevent heat loss.
Why it matters:
Improves hot water efficiency
Reduces overall heating demand
Costs very little and installs in seconds
This is another small upgrade that adds up during the assessment.
7. Improve Loft Hatch Insulation
Even if your loft is insulated, a poorly sealed hatch can leak heat.
Quick improvements:
Add a strip of insulation around the hatch
Ensure it closes tightly
Place a small insulation board on top
This addresses a common EPC red flag: poor insulation continuity.
8. Provide Documentation to the Assessor
If you’ve already made upgrades but haven’t documented them, your rating could drop unnecessarily.
Gather proof of:
Boiler installation date
Loft insulation thickness
Double glazing installation
Cavity wall insulation
Solar PV or heating upgrades
Without proof, an assessor must assume the lowest possible rating.
If you’re unsure what’s needed, our EPC Assessor Services page explains the process clearly.
9. Check Heating Controls
Functional heating controls can slightly improve your EPC rating.
Make sure:
Thermostats work properly
Room thermostats are not blocked
TRVs (radiator valves) turn freely
Even small adjustments make a noticeable impression during inspection.
10. Tidy Up Access Areas
EPC assessments require access to:
Loft spaces
Boilers
Hot water cylinders
Heating controls
Meters
A clear, accessible environment ensures a smoother inspection and reduces the chance of skipped elements that may lower your rating.
Want a Higher EPC Rating?
If you’re preparing your property for a sale, rental, or remortgage, a higher EPC rating can significantly increase value and compliance.
You can learn more about how EPCs work on our About Us Page or speak with a certified assessor through our Contact Page.

Final Tip
These last-minute fixes are simple but surprisingly effective. Combined, they create a more efficient environment that assessors instantly recognise — helping you achieve a stronger EPC rating with minimal cost.
