Leading the Way in Energy and Property Solutions.
If you own, rent, or manage property in London, you’ve likely heard of an Energy Performance Certificate (EPC) — but what exactly is it, and why does it matter? Whether you’re preparing to sell your home, lease a flat, or ensure compliance with UK energy regulations, understanding EPC requirements is essential.
An Energy Performance Certificate (EPC) assesses the energy efficiency of a building. It provides a rating from A (most efficient) to G (least efficient) and includes recommendations to improve efficiency. EPCs are legally required in most cases when a property is built, sold, or rented.
London’s dense population and urban energy demands make energy efficiency a key concern. Local councils and national legislation aim to reduce carbon emissions, and EPCs play a central role in this effort.
An EPC is:
Required by law for residential and commercial properties during sale or lease.
Valid for 10 years once issued.
Used to help buyers and tenants understand ongoing energy costs.
You need an EPC in London if you are:
Selling or renting out a residential or commercial property.
Constructing a new building.
Renovating a property in a way that impacts its energy performance.
Exceptions exist for listed buildings, temporary structures, and certain places of worship, but most properties will need one.
Getting an EPC is a straightforward process:
Contact an accredited domestic energy assessor.
Schedule a site visit — the assessor will examine your insulation, heating system, lighting, windows, and more.
Receive your EPC and energy improvement recommendations within 24–72 hours.
Costs typically range from £45 to £120 depending on property size and location.
Failing to provide an EPC when required can lead to fines of up to £5,000. Letting agents and landlords in London are under increased scrutiny to ensure compliance with EPC regulations.
Improving your EPC rating can enhance property value, reduce energy bills, and attract tenants. Common improvements include:
Adding loft or wall insulation
Installing double glazing
Upgrading heating systems
Switching to energy-efficient lighting
Navigating EPC requirements in London doesn’t need to be complicated. Whether you’re a homeowner, landlord, or business owner, securing an EPC is a critical step in staying compliant and energy-conscious.
