What is an EPC rating?
An Energy Performance Certificate (EPC) measures how energy efficient a property is, giving it a rating from A (most efficient) to G (least efficient). The rating is based on factors such as insulation, heating systems, glazing, lighting and renewable energy sources.
An EPC assessment typically takes around 30–60 minutes to complete, depending on the size and complexity of the property.

Why improving your EPC rating matters
A better EPC rating can benefit homeowners, landlords and buyers in several ways:
- Lower energy bills
- Improved property value
- More attractive to buyers and tenants
- Helps landlords meet current and future efficiency regulations
Many landlords are already improving their ratings ahead of potential government requirements for rental properties to reach a minimum EPC rating.
Upgrade your insulation
Insulation is one of the most effective ways to improve your EPC rating.
Key areas include:
- Loft insulation
- Cavity wall insulation
- Floor insulation
Heat loss through poorly insulated roofs and walls can significantly impact a property's EPC score.
Improve your heating system
Your boiler and heating controls have a large influence on EPC calculations. Replacing an old inefficient boiler with a modern condensing boiler can improve the rating considerably.
Other useful upgrades include:
- Thermostatic radiator valves
- Smart thermostats
- Modern heating controls
Switch to energy-efficient lighting
Lighting plays a smaller role in EPC calculations but is one of the easiest improvements to make. Replacing traditional bulbs with LED lighting throughout the property can help improve the overall rating.
Upgrade windows and glazing
Double glazing reduces heat loss and improves a property's energy efficiency. If your home still has single-glazed windows, upgrading them can contribute to a higher EPC score.
Consider renewable energy
Renewable energy systems can significantly boost an EPC rating. Options include:
- Solar panels
- Air source heat pumps
- Solar water heating
While these upgrades require larger investment, they can greatly improve energy efficiency and long-term running costs.
Provide documentation during the EPC assessment
During an EPC assessment, assessors can only record improvements that are visible or supported by documentation.
If you've installed insulation or upgraded heating systems, providing documentation such as installation certificates can help ensure these improvements are reflected in the EPC rating.
