ECO Frequently Asked Questions

FAQ – Energy Company Obligation Scheme (ECO)

We have put together some Frequently Asked Questions for you to use as a quick reference guide and to help you understand the scheme basics.


What is ECO?

The Energy Company Obligation (ECO) is a government scheme introduced in January 2013 which obligates larger suppliers to deliver energy efficiency measures to domestic premises in mainland UK.

All the larger energy companies are given set obligations to install more efficient boilers and insulation in order to achieve this reduction in energy use and heating cost.


What are the different obligations under ECO?

HHCRO - Home Heating Cost Reduction Obligation

This section of the scheme is intended to make heating your home more affordable. To be eligible under HHCRO you will need to be claiming certain benefits. The measures available are any that will improve low income or vulnerable household’s ability to heat their homes, such as cavity wall insulation, loft insulation or boiler replacements


CERO - Carbon Emissions Reduction Obligation

This obligation provides solid wall, cavity wall and loft insulation measures, and connections to district heating systems, alongside secondary measures including double glazing and draught proofing.


CSCO - Carbon Saving Community Obligation

This provides insulation measures and connections to district heating systems to households in specified low income areas. Ofgem has published a tool to assist installers and customers to identify eligible CSCO and CSCO rural areas.


How do I qualify for Energy Saving Home Improvements?

You eligibility is based on:-

  • Your postcode / area where you live
  • The type of house you have
  • Any government benefits that you or someone else in your household receives

To qualify for these you must either own your home or be a private tenant (permission is required from your landlord before any home improvement works are carried out).


Do I need to be a Co-operative Energy Customer to qualify?

No, Co-operative Energy can offer these improvements to anyone living in mainland UK, regardless of their current energy provider.



If I’m eligible, what Energy Saving Home Improvements could I get?

Those that qualify may be eligible for –

  • Free or subsidised cavity wall insulation
  • Free or subsidised loft insulation
  • Free or subsidised energy efficient replacement boiler


How do I know if my home is suitable for the available improvements?

Once your application has been checked, our supplier will come to your house to assess the most appropriate improvements for your home.


How much money will these improvements save me?

This depends on the size and type of property. Cavity wall insulation alone could save a typical house up to £160 a year and depending on the age and condition of your current boiler, replacing it could save up to £300 annually.


If I have the work done under the ECO scheme, will the Co-operative Energy try to sign me up as a customer?

No, your details are only used to help make your home more energy efficient.


What type of boiler can I get under ECO?

This depends on the type of property; on assessment our supplier will be able to recommend a boiler that will be most suitable.


What is Cavity wall insulation?

Many properties were built with a gap between the two layers of the outer wall. Cavity wall insulation is used to reduce heat loss by filling in this space, which reduces the amount of fuel required to heat your home.


What type of insulation is used for filling cavity walls?

Certain properties may require different insulation, our supplier will recommend the most appropriate for your property.


Will having cavity wall insulation installed damage my property?

Cavity wall insulation is installed by the installer drilling small holes in the external brickwork; the insulating material is then pumped through the holes into the cavity. The holes are then filled in using materials that match your brickwork. Depending on the size of the property, this whole process can take as little as 2 hours.


How do I apply?

Please complete the ECO application form. If you are eligible based on the data you’ve provided then our supplier will get in touch with you directly. If we need further information then a member of the ECO team will contact you first.
