What is it?

ECO (Energy Company Obligation) is a government scheme that gives people subsidised energy efficiency improvements for their home. Its main aim is to help people keep warm, save energy and lower their energy bills. By insulating our customers’ homes and providing more efficient ways of heating, we’re helping to cut the amount of energy you use.

There are three improvements available:

Loft insulation

  • By insulating your loft, you can reduce the amount of heat lost and save money on your heating bills
  • Loft insulation is quick to install and requires only minimal disruption
  • No maintenance once installed
Cavity Wall

Cavity wall insulation:

  • If your home was built after 1920, it’s likely to have cavity walls
  • By insulating this gap, you can reduce the amount of heat lost and save money off your heating bills
  • Cavity wall insulation is quick to install
Man with boiler

Replacement gas boiler:

  • Could reduce your running costs
  • Could reduce risk of breakdowns
  • All new boilers through ECO come with a minimum one year warranty

How do I apply?

The first thing to do is call us on 0800 404 9084. We’ll run through the eligibility criteria (above) to check you qualify. If you qualify, we’ll set up a free, no obligation home assessment with one of our qualified installers. They’ll visit to check your house is suitable. It'll be around four weeks after you first get in touch with us.

What happens at the assessment?

The installation company will take some measurements and photos. The assessment will take around two to three hours, depending on the type of property you live in. You might need to show them some paperwork (like a tenancy agreement or proof of benefits). They’ll also need to do a technical survey – they’ll either do this on the same day as the assessment, or make an appointment with you to come back another day.

The installer will then tell you which improvements will be best for you. There might be some extra costs you need to pay but they’ll let you know what these are before they start the work.
