Understanding EPC Ratings: What They Mean for Surrey Homeowners

26th Nov 2025

When it comes to making your home more energy-efficient, one of the most important things to understand is your EPC rating. Short for Energy Performance Certificate, it’s a key indicator of how much energy your property uses, how costly it is to heat and light, and how environmentally friendly it is.

Whether you’re looking to buy, sell, or improve your home, knowing where your property stands can make a real difference.

What is an EPC Rating?

An EPC is a standard report that gives your home an efficiency score from A to G, with A being the most efficient and G the least. The certificate shows how much energy your home consumes and offers suggestions for improvement.

It also provides an estimated cost for running your home and lists practical steps to help reduce your energy use. For example, improving insulation, upgrading windows, or adding solar panels can all help boost your score and reduce bills.

Every EPC is valid for 10 years and is carried out by an accredited domestic energy assessor.

Why EPC Ratings Matter

EPC ratings aren’t just for compliance – they have a direct impact on your home’s comfort, costs, and value.

  • Lower energy bills: Homes with higher EPC ratings are more efficient, meaning less wasted heat and lower running costs.

  • Increased property value: Buyers are increasingly looking for energy-efficient homes, and a strong EPC score can make your property more attractive on the Surrey market.

  • Reduced carbon footprint: Improving your rating means you’re using energy more responsibly and helping cut carbon emissions.

  • Legal requirements: If you’re selling or renting out your property, you’ll need an up-to-date EPC before it’s listed.

For landlords, the rules are even stricter – rental homes must meet a minimum EPC rating of E or above.

How to Improve Your EPC Rating

The good news is that improving your EPC rating doesn’t have to be complicated. Many changes are simple, affordable, and make a noticeable difference to your comfort and bills.

Here are some of the most effective ways to raise your home’s score:

  • Upgrade your insulation: Proper insulation keeps heat inside, reducing how much energy you need to stay warm.

  • Fit energy-efficient windows and doors: Modern glazing prevents draughts and improves overall efficiency, and our sister company Sheerwater Glass can help make that upgrade effortless.

  • Install a renewable energy system: Adding solar panels or a battery storage system can dramatically improve your EPC rating and cut long-term costs.

At Sheerwater Solar, we help homeowners across Surrey transform their energy performance by installing high-efficiency solar systems designed to suit their property and lifestyle.

EPC Ratings and Solar Panels

Solar panels are one of the most effective ways to increase your EPC rating. By generating your own clean electricity, you reduce reliance on the grid and lower your household’s energy use. This not only improves your score but also helps future-proof your home against rising energy costs.

A solar-powered home tends to achieve a higher EPC rating, making it more appealing to potential buyers. Many homeowners see this as an investment that pays back through lower bills, increased property value, and a reduced carbon footprint.

Why It Matters in Surrey

Surrey homes come in all shapes and sizes – from period cottages to new-builds – but every property can benefit from being more energy-efficient. With energy prices fluctuating and sustainability becoming a top priority for buyers, improving your EPC rating is one of the smartest steps you can take.

Whether you’re preparing to sell or simply want to live more sustainably, understanding your EPC is the first step toward meaningful change.
