Understanding EPC Ratings: What Every Landlord Needs to Know

An Energy Performance Certificate (EPC) rates a property's energy efficiency on a scale from A (most efficient) to G (least efficient). All rental properties in England must have a valid EPC — and since 2020, the minimum standard for new tenancies has been E. Understanding your property's rating and what affects it is increasingly important for landlords.

Why EPC ratings matter more than ever

Tenants are increasingly energy-conscious, and a poor EPC rating can put off quality applicants — particularly as energy bills have risen sharply in recent years. Properties rated C or above consistently attract more enquiries and let faster in our experience. Beyond tenant appeal, the government has signalled plans to raise the minimum standard to C for new tenancies, though the timeline has shifted several times.

Common improvements and their impact

The most cost-effective improvements for most East London properties are loft insulation, cavity wall insulation (where applicable), and upgrading to a modern condensing boiler. LED lighting throughout and double glazing also contribute meaningfully to the rating. Many of these improvements qualify for government grants or subsidies — speak to us and we can point you towards the current schemes available.

Getting your EPC assessed

EPCs must be carried out by an accredited domestic energy assessor and are valid for 10 years. If your current EPC is more than five years old, it's worth getting a new one — the methodology has been updated and many properties now achieve a better rating than their older certificate suggests. We can recommend trusted assessors in the area.
