In the current UK property landscape, an Energy Performance Certificate (EPC) is much more than a mandatory document, it is the baseline for your property’s future value and legal rentability. An EPC measures the energy efficiency of a building on a scale from A (most efficient) to G (least efficient) and is a legal requirement whenever a property is built, sold, or rented.
With the government’s recent “Warm Homes Plan” announcements and the proposed trajectory toward a minimum EPC C rating for all rental properties by 2030, landlords and homeowners are navigating a critical transition. While many of the stricter requirements are currently in the consultation phase, the shift toward a “fabric-first” approach prioritising insulation and windows, is already influencing buyer and tenant behaviour across the South East.
Under the Minimum Energy Efficiency Standards (MEES), having a valid EPC is a strict legal obligation for several reasons:
At First Certify, we provide a comprehensive look at your property’s efficiency through a professional domestic assessment. A qualified Domestic Energy Assessor (DEA) will visit your property for a non-invasive survey, typically lasting 30 to 60 minutes. We examine:
Using the latest RdSAP 10 methodology, we process this data to produce your certificate and a set of tailored recommendations. To help market your property more effectively, we can also provide Comprehensive Floor Plans. In 2026, this system has partially moved away from “assumptions,” meaning evidence (like invoices for insulation) is now vital for an accurate score.

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 register. This ensures you stay compliant with regulations and gives you a clear starting point if an updated certificate is needed. If you still require an EPC, you can Book Online Here.
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.
