Whether you’re selling, letting, or managing a property, you’ve likely come across the term EPC—but what exactly is it, and why does it matter so much?
At Oakfield Estate Agents, we work with landlords, sellers, and buyers across East Sussex, and EPCs (Energy Performance Certificates) come up daily. Here’s your complete, jargon-free guide to understanding EPCs, how they affect you, and what you need to do to stay compliant.
What Is an EPC?
An Energy Performance Certificate (EPC) is a legal document that rates the energy efficiency of a property on a scale from A (most efficient) to G (least efficient). It gives a snapshot of how energy-efficient a property is and includes:
- Current and potential energy ratings
- Estimated running costs (heating, lighting, hot water)
- Recommendations for improvements to boost efficiency
Who Needs an EPC?
You’ll need a valid EPC if you are:
- Selling a property
- Letting a property to new tenants
- Building a new property
EPCs are valid for 10 years, and it’s illegal to market a property for sale or rent without one.
EPC Rules for Landlords
This is where it gets especially important. Currently, rental properties in England and Wales must have a minimum EPC rating of E. Properties rated F or G cannot be legally let unless they qualify for an exemption.
Coming Soon?
There have been proposals to raise this minimum to C for new tenancies (potentially from 2028), though this has not yet been finalised. It’s wise for landlords to start improving now to future-proof their investments.
Why Does It Matter?
- Compliance: Marketing or letting a property without a valid EPC can lead to fines of up to £5,000.
- Marketability: Energy-efficient homes attract more buyers and tenants—and can even fetch higher prices or rents.
- Cost savings: An upgraded EPC often means lower energy bills for occupants.
- Sustainability: Better ratings reduce environmental impact, appealing to eco-conscious renters and buyers.
How to Improve Your EPC Rating
Improving your rating doesn’t always mean major renovation. Consider:
- Upgrading loft or cavity wall insulation
- Installing a modern boiler or heating controls
- Replacing single-glazed windows with double glazing
- Adding low-energy lighting
- Using smart thermostats or heating zones
