A valid Energy Performance Certificate (EPC) is a legal requirement for selling or renting any property in the UK. Providing a rating from Band A (Most Efficient) to Band G (Least Efficient), this certificate is valid for 10 years.
It is currently unlawful to let a property with an EPC rating below Band E. With government targets aiming for Band C by 2030, ensuring your property is correctly assessed is vital for long-term value and compliance. We provide professional assessments to help you understand and improve your rating.
Failing to provide a tenant with a copy of a valid EPC at the start of their tenancy can invalidate your ability to serve a Section 21 possession notice later.
Failure to hold a valid EPC when required can result in a fine of up to £5,000 for residential properties, enforced by local authorities.
As energy costs rise, high EPC ratings are becoming a key selling point. A higher rating not only reduces utility bills for tenants but also makes the property more attractive to green mortgage lenders and climate-conscious buyers.

Knowing your EPC status is essential, whether you’re looking to sell, rent, or improve energy efficiency. You can quickly and easily check if your property already has a valid EPC by visiting the official UK government EPC register.
This ensures you don't pay for a new report unnecessarily. If you still require a new certificate, you can book online with us.
Q: How long does an EPC assessment take?
An EPC assessment typically takes less than an hour. However, the duration may vary depending on the complexity of the property’s layout, such as loft conversions, extensions, or other unique features.
Q: Do I need to be present during the EPC assessment?
While it’s not necessary for you to be present during the assessment, it can be helpful to answer any questions the assessor may have about the property. The assessment usually involves a walk-through to gather information about the building’s energy use.
Q: How long is an EPC certificate valid for?
An EPC certificate is valid for 10 years. However, you may want to have your property reassessed sooner if you’ve made significant improvements to its energy efficiency.
Q: Is an EPC required for renting out my property?
Yes, in the UK, an EPC is required for properties being rented or sold. Landlords must provide a valid EPC to tenants at the start of a tenancy. The rating must be at least an E to meet legal requirements.
