Eligible customers living in a home with a low EPC rating will be offered a package of free energy-saving measures and heating improvements. The ECO4 scheme is not a way to only replace or upgrade your boiler.

What is the ECO4 Scheme?
ECO4 is the fourth phase of the Government’s Energy Company Obligation. It started in August 2022 and it's due to continue until 31 March 2026.

Here are some of the measures which will make up a package under ECO4

Stop heat in your home escaping
Did you know that a typical home without insulation can lose 33% of its heat through its walls and 25% through the roof?
Insulating your home properly can improve keeping the heat in and reduce heat loss.
Well-insulated homes are much better for your health too. There is no question that living in a cold home can cause health issues, and heighten pre-existing ones. Insulating your home to the latest guidance also means that you can prevent damp, which can cause mould and mildew.
Adding insulation to your loft, walls and floor will help you keep your home warm, wasting less energy and lowering your home's carbon emissions.

Upgrade your electric heating system
Upgrading your existing electric heating system with a more energy-efficient solution or adding a zero carbon heating system like an air source heat pump will keep you warm and save the planet.
Electric heater designs have come a long way. New models of storage heaters and electric radiators include energy efficiency features such as;
- Smart controls help you only heat the rooms you want
- A highly accurate thermostat, 7-day times for 24-hour control
- Energy-saving technologies such as 'open window detection' and 'adaptive start'

Upgrade your boiler
The scheme requires that the fabric of a property (walls, floors and roofs) are considered before replacing a heating system. Upgrading your old boiler with a more efficient model will help make your home more energy efficient. Boilers, like other domestic appliances, have efficiency ratings of A-G. Modern boilers have to be A-rated and show it in their literature.
