Tips
- Aim for around 270mm of mineral wool insulation where possible.
- Ensure insulation is laid evenly across the loft floor.
- Avoid compressing insulation with heavy boarding.
- Insulate loft hatches where practical.
EPC Impact
Good loft insulation can noticeably improve EPC ratings, especially in older properties.
Cavity Insulation
Why it matters
Uninsulated cavity walls can lose a large amount of heat.
Tips
- Have the cavity checked by a reputable installer before filling.
- Ensure the walls are suitable and free from damp issues.
- Retain any installation certificates and guarantees.
EPC Impact
Property installed cavity wall insulation can provide a strong EPC improvement and reduce heating costs.
Floor Insulation
Floor insulation is often overlooked but can make a property feel noticeably warmer.
Why it matters
Cold floors increase heat loss and reduce comfort.
Tips
- Suspended timber floors can often be insulated between joists.
- Solid floors may sometimes be insulated during renovations.
- Thick underlay and carpets can also help reduce heat loss.
EPC Impact
Solar PV can improve EPC scores by reducing calculated electricity costs.
Boilers
Your boiler has a major influence on your EPC rating.
Why it matters
Older boilers are often far less emicient tan modern condensing boilers.
Tips
- Modern condensing boilers are usually far more efficient.
-
Ensure heating controls are upgraded too:
- Thermostatic radiator valves (TRVs)
- Programmers
- Smart thermostats - Service boilers regularly to maintain efficiency.
EPC Impact

Heat Pumps
Heat pumps are becoming increasingly popular and can score very well on EPCs when installed correctly.
Why it matters
Heat pumps use electricity very efficiently to heat homes.
Tips
- Insulation upgrades should usually be completed first.
- Larger radiators or underfloor heating may be required.
- Low flow temperature systems generally perform best.
-
Use experienced, MCS-accredited installers.
EPC Impact
Heat pumps can provide excellent EPC results, especially in well-insulated homes.
Double Glazing
Windows play an important role in energy efficiency.
Why it matters
Older single glazing loses heat quickly and can create draughts.
Tips
- Upgrade older single glazing to modern double glazing where possible.
- Modern low-E glass performs best.
- Ensure windows are well sealed and draught proofed.
- Retain any FENSA or installation certificates.
EPC Impact
Double glazing can improve both comfort and EPC ratings.
Solar PV
Solar photovoltaic (PV) panels generate electricity from sunlight.
Why it matters
They reduce electricity usage from the grid and can lower running costs.
Tips
- South-facing roofs generally perform best.
- Battery storage can improve savings.
- Keep documentation for installation and specifications.
EPC Impact
Solar PV can improve EPC scores by reducing calculated electricity
Solar Hot Water
Solar thermal systems use the sun to help heat hot water.
Why it matters
They reduce the energy required for Tips hot water production.
Tips
- Works best with a suitable hot water cylinder.
- South-facing roofs usually provide the best performance.
- Regular maintenance helps efficiency.
EPC Impact
Solar hot water systems can positively contribute to an EPC rating
Final Advice
The best improvements are usually achieved by combining:
- Good insulation
- Efficient heating
- Effective heating controls
- Renewable technologies where suitable
Every property is different, and some upgrades provide far better value than others depending on the building type and age.
