When you hear about improving your home energy rating, it’s easy to think it’s just another box to tick when selling or renting your property.
But your EPC rating (Energy Performance Certificate) is more than that. It’s a measure of how efficiently your home uses energy – and it can have a big impact on your house value, monthly bills, and even how attractive your home is to potential buyers.
At Wright Renewables, we help households across Worksop, Nottinghamshire and South Yorkshire improve their energy efficiency every day through solar panel installation and air source heat pump systems. But understanding your EPC is the first step to making smarter choices.
The EPC Register is the UK government’s official database of Energy Performance Certificates. If you’ve had an EPC done in the last 10 years, your property should be listed here: www.gov.uk/find-energy-certificate
Each certificate gives a rating from A (most efficient) to G (least efficient), alongside recommendations to improve your score. It’s a legal requirement when selling or renting out a property, and it’s public—so buyers and renters can see it before even stepping through the door.
“We often help homeowners boost their EPC by installing solar PV systems or heat pumps. You’d be surprised how much of a difference it makes, not just in the score, but in running costs,” says Lee Rolfle, Managing Director at Wright Renewables.
An EPC typically costs between £60 and £120, depending on the size of the property and the assessor. It’s a small investment considering it’s valid for 10 years—and can directly influence how quickly your property sells or rents.
A higher EPC can add serious value. According to research from the Department for Energy Security & Net Zero, improving your rating from band G to E can boost property value by around 6%, while moving from band D to B can lift it by as much as 14% (source).
Only accredited Domestic Energy Assessors (DEAs) can issue a legal EPC. These assessors are registered with a government-approved scheme and trained to evaluate your home’s insulation, heating systems, glazing, and renewable energy technologies like solar panels and heat pumps.
You can find a certified assessor through:
It’s worth ensuring your chosen assessor is thorough—because installations like solar PV or air source heat pumps must be properly documented to contribute to your rating.
EPC ratings are split into bands from A to G. Here's a breakdown:
Most UK homes currently sit around band D or E. The government has announced that new rental properties will be required to reach a minimum of band C by 2028, part of a wider push to improve the country’s housing stock.
The good news? With the right upgrades—like fitting solar panels in Nottinghamshire or upgrading to a heat pump system—you can often jump one or two bands quite quickly.
Absolutely. Both solar PV and air source heat pumps are counted as energy-efficient systems within the EPC framework. They reduce your home’s reliance on fossil fuels and cut both your bills and carbon footprint.
According to the Energy Saving Trust, a typical solar panel installation can:
And as a trusted OVO Energy partner, Wright Renewables ensures all renewable heating systems we install are fully compliant and contribute to a better EPC.
Whether you’re staying put, selling up, or renting out, here’s why your EPC score matters:
Here are a few steps you can take:
Your EPC is more than a number—it’s a reflection of how comfortable, affordable, and future-ready your home really is. Whether you’re looking to sell, rent, or simply make your home more energy efficient, small upgrades can go a long way.
