What is the Energy Company Obligation?

The Energy Company Obligation (ECO) Scheme was set up in April 2013. The purpose of the scheme is to help eligible customers make their homes more energy-efficient by installing free energy-saving measures and heating improvements. This helps customers keep their homes warm and running more efficiently.

Customers will need to take a package of energy efficiency improvements rather than just one. Eligible customers will have a survey carried out on their homes to make sure their property is suitable for these improvements.

Just fill in your details on our form and someone will get back to you to go through your options and the next steps.

Stop heat in your home escaping

Did you know that a typical home with no insulation can lose 33% of heat through its walls and 25% through the roof?

Insulating your home properly can improve keeping the heat in and also improve things like

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 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 or replace your boiler

Upgrading or replacing 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.


Fill in your details and one of our installers will call you back to go through your options and arrange a FREE home survey to see which improvements are best for you.

Frequently asked questions about the Energy Company Obligation (ECO)

The ECO scheme has been designed by the government to help improve the most energy inefficient properties across the UK.

As part of this, the scheme requires that the fabric of a property (walls, floors & roofs) are improved before replacing a heating system. If all insulation work has been done and is up to the current standards it may be possible to replace a broken heating system but further scheme restrictions may apply.

In order to be eligible for the ECO scheme, your property must meet the minimum EPC band improvement. The package of measures identified by the installer will help you meet this requirement and must be installed to be eligible for the scheme.

The ECO scheme is not a grant scheme. Payments are made directly to the installer based on the work completed in your home. EDF only uses installers that meet the accreditation requirements as set by the government.

When insulating your home it's important to have adequate air flow throughout the property, therefore it may be required to install ventilation measures to help with this.
