Energy Companies Obligation (ECO)


What is ECO?

ECO is an energy efficiency programme that was introduced into Great Britain at the beginning of 2013. It replaces two previous schemes, the Carbon Emissions Reduction Target (CERT) and the Community Energy Saving Programme (CESP).

ECO places legal obligations on the larger energy suppliers to deliver energy efficiency measures to domestic energy users. It operates alongside the Green Deal which is designed to help people make energy efficiency improvements to buildings by allowing them to pay the costs through their energy bills rather than upfront.

ECO is intended to work alongside the Green Deal to provide additional support in the domestic sector, with a particular focus on vulnerable consumer groups and hard-to-treat homes.

Under the rules of ECO, energy suppliers are obliged to help improve the energy efficiency of their domestic customers’ buildings.

How can I benefit from ECO?

You may be eligible if you are a domestic energy user and you and/or your property meets the eligibility requirements under one of the three obligations then you would possibly be eligible for energy efficiency measures to be installed under the scheme, regardless of whether your energy supplier is obligated under ECO:


Carbon Emissions Reduction Obligation (CERO)

CERO is directed at loft and wall insulation, which is the primary measures that the Government intends to be promoted under this target. Other insulation measures and connections to district heating systems are also eligible if they are part of a package.


Carbon Saving Community Obligation (CSCO)

CSCO focuses on the provision of insulation measures and connections to district heating systems to domestic energy users that live within an area of low income. At least 15% of the target must be achieved in low income and vulnerable households located in rural areas.


Home Heating Cost Reduction Obligation (HHCRO)

HHCRO covers measures that improve the ability of low income and vulnerable households (the ‘Affordable Warmth Group’) to affordably heat their homes, including the replacement or repair of a qualifying boiler.
