Property assessment
We look at your current EPC, the loft, walls, windows, ventilation and heating to see where the property loses most heat.

New EPC
An independent accredited energy assessor carries out a new EPC to record the improved rating.
Improvements we carry out
The measures that usually make the biggest difference
Loft insulation
Topping up or replacing loft insulation to the recommended depth is often the quickest win on an EPC.
Cavity wall insulation
Filling empty cavities cuts heat loss through the walls of suitable homes built from the 1920s onwards.
Ventilation
Better insulated homes need good ventilation, so condensation and mould do not follow the improvements.
Heating and renewables
Where insulation alone is not enough, heating upgrades and solar panels can lift the rating further.
Landlords and homeowners
Why EPC C matters
For landlords, rented homes in England and Wales currently need at least an E, and the government has set out plans to raise the minimum for privately rented homes to C. Planning the work now spreads the cost and avoids a rush later.
For homeowners, a better rating usually means a warmer home that costs less to heat, and an EPC is one of the first things buyers and lenders look at.

FAQ
EPC questions
How do I improve my EPC rating from D to C?
Most homes move up by reducing heat loss first: topping up or replacing loft insulation, filling empty cavity walls, and fixing draughts, then improving heating controls or the heating system where needed. Which measures matter depends on your property, which is why we start with an assessment.
Can you guarantee an EPC C rating?
Not before an assessment. We target C and recommend the improvements most likely to get there. The new rating is issued by an independent accredited energy assessor once the work is done.
Do landlords need EPC C?
Rented homes in England and Wales currently need at least an E. The government has set out plans to raise the minimum for privately rented homes to C, so many landlords are improving their properties now rather than later.
Do I need a new EPC after the work?
Yes, to show the improved rating you need a new EPC from an accredited domestic energy assessor. We can point you to one once the improvements are complete.
Is funding available for EPC improvements?
Some households qualify for government-backed schemes, mainly for insulation and heating. Funding depends on your circumstances and each scheme's rules, so we check what may apply before any work is agreed.
