How to Improve Your EPC Rating and Save on Energy Bills

Energy-efficient windows in an old home

An Energy Performance Certificate (EPC) is a valuable tool for homeowners and landlords, providing insight into the energy efficiency of your property. With rising energy costs, improving your EPC rating not only helps to reduce your carbon footprint but also lowers your energy bills.


Here are some effective ways to boost your EPC rating and start saving money on your energy bills:


1. Upgrade Insulation

One of the most effective ways to improve your EPC rating is by enhancing the insulation in your home. Good insulation helps to keep the heat in during winter and the cool air in during summer, reducing the need for constant heating or cooling. Consider upgrading:

  • Loft Insulation: A well-insulated loft can save up to £250 annually on heating costs.

  • Cavity Wall Insulation: This prevents heat from escaping through the walls.

  • Floor Insulation: Particularly beneficial for ground-floor rooms, helping to keep your home warmer.


2. Install Energy-Efficient Windows

Windows that are double-glazed or have advanced insulating properties help prevent heat from escaping and cold from entering. Replacing old, single-glazed windows can result in a significant improvement in your home’s EPC rating and reduce heating costs by around 10-15%.


3. Upgrade Your Heating System

An old, inefficient heating system could be wasting energy and increasing your energy bills. Consider replacing an old boiler with a condensing boiler, which is more efficient and will use less energy to heat your home. If your home relies on electric heating, explore switching to a gas or heat pump system, which are typically more efficient.


4. Use Energy-Efficient Appliances

Upgrading your appliances to energy-efficient models can significantly reduce your energy usage. When buying new appliances, look for the Energy Star label or choose products with a higher energy efficiency rating (A+++, A++). This applies to everything from refrigerators to washing machines, and even your lighting.


5. Switch to Renewable Energy Sources

Investing in renewable energy sources, such as solar panels or a solar water heating system, can improve your EPC rating and lower your energy costs in the long run. By generating your own electricity, you’ll be less reliant on the national grid and save on energy bills.


6. Conduct Regular Maintenance

Regular maintenance of your home’s systems, such as the heating and cooling units, will ensure they operate at peak efficiency. Cleaning ducts, checking for leaks, and scheduling professional maintenance for your boiler or air conditioning system can prevent energy wastage and prolong the lifespan of these systems.


7. Improve Ventilation

A well-ventilated home is essential for maintaining energy efficiency and preventing condensation and mold growth. Controlled ventilation systems such as heat recovery ventilators (HRVs) help to improve air quality while reducing heat loss.


8. Consider External Wall Insulation

External wall insulation can significantly improve your EPC rating, particularly if your home is in need of a major energy efficiency upgrade. This involves adding insulation to the outside of your home, which reduces heat loss and helps you save money on heating.


Why EPC Ratings Matter

A higher EPC rating means your property is more energy-efficient, which translates into lower energy consumption and lower bills. Moreover, when it comes to selling or renting a property, homes with higher EPC ratings are more attractive to potential buyers or tenants, who are becoming increasingly energy-conscious.


Where to Get Help

Improving your EPC rating can seem like a big task, but it doesn’t have to be. You can consult with professional energy assessors or qualified tradespeople for advice on how best to improve your property’s energy performance. A variety of EPC services can provide a thorough audit and actionable recommendations tailored to your home.
