- What is an EPC rating?
- An Energy Performance Certificate (EPC) rates a property's energy efficiency from A (most efficient) to G (least efficient). It is required by law whenever a property is sold, let or built in England and Wales.
- How long does an EPC last?
- An EPC is valid for 10 years from the date it was lodged. After 10 years a new assessment is required before the property can be sold or let again.
- What EPC rating do landlords need?
- Since April 2020, rented properties in England and Wales must have a minimum EPC rating of E. The Government has consulted on raising this to C by 2028 for new tenancies — investors should factor potential upgrade costs into their due diligence.
- Does an EPC affect property value?
- Yes. Research consistently shows that higher EPC ratings command a price premium. A poor rating can suppress both sale price and rental demand, while improvements to reach a C or above can add measurable value.
- Can I check an EPC for any property in the UK?
- This tool covers England and Wales only. Scotland has a separate register at energysavingtrust.org.uk and Northern Ireland uses the Landmark register. Data comes from the official MHCLG EPC register.
- What if no EPC is found for a property?
- Some properties have never had an EPC lodged — typically those not sold or let since the register began. If no certificate is found, you may need to commission a new EPC assessment before purchase or letting.
- How accurate is this EPC data?
- Data is sourced directly from the official MHCLG EPC register via the Open Data Communities API. It reflects the most recently lodged certificate for each property.
