What is an EPC?

An Energy Performance Certificate rates a property’s energy efficiency on a scale from A (most efficient) to G (least efficient). It includes:

• A current and potential energy rating

• Estimated energy costs

• Recommendations to improve efficiency (e.g., insulation, boiler upgrades)

• Environmental impact in terms of CO₂ emissions

Who Needs an EPC?

You need an EPC if you're:

• Selling or renting a residential or commercial property

• Constructing a new property

• Making major modifications to a building

Some exceptions apply (e.g., listed buildings or temporary structures), but for most transactions, it’s a must-have.

How Long Does It Last?

An EPC is valid for 10 years. However, if you’ve made improvements to your property (like upgrading heating systems or insulation), getting a new EPC could reflect a better rating.

Minimum Requirements for Rentals

For landlords, there’s a legal requirement that all rental properties in England and Wales must have a minimum EPC rating of E. Renting out a property with a lower rating is not allowed unless you have an exemption.

Why It Matters

A good EPC rating can:

• Boost your property’s value

• Make it more attractive to buyers or tenants

• Save money on energy bills

• Reduce your carbon footprint
