You may be eligible for a grant for improvements to your home thermal efficiency, such as:

  • new central heating systems
  • upgrades to existing heating systems
  • insulation measures

Under the Energy Company Obligation (ECO) Local Flexibility and ECO3, the major energy producers/suppliers are required by central government to make funds available and allocate to qualifying householders. This allows them to install fully-funded or subsidised energy saving measures in the home, which have been declared eligible by the council (see our Statement of Intent (pdf 3MB) (SOI))

The ECO3 funding scheme ran from 2018 and was due to end 31st March 2022. However, the necessary legislation was not laid in parliament for ECO4, which was due to commence 1st April 2022 and runs until 31st March 2026. Therefore, an ‘ECO3 interim delivery’ period has been agreed until 30th June 2022, where measures can continue to be installed to ECO3 rules with some expectations.

ECO4 will support low income households living in the least efficient homes with an Energy Performance Certificate (EPC) rated D to G (some expectations apply). More information will be available as soon as the scheme details are confirmed.

Am I eligible to apply?

In order to be eligible for this funding, a household must fit one or more of the following criteria:

  1. living in 'fuel poverty' but not in receipt of certain state benefits
  2. low income and vulnerability to cold
  3. solid wall insulation ‘in-fill’

1. To be eligible under the 'fuel poverty' criteria, households will need to have:

  • income related benefit - Housing benefit of Council tax reduction/support (not single person occupancy), or
  • household income (after tax, rent or mortgage, council tax and energy payments) per composition (single person - £25,000 per annum, household with 2 or more people - £30,000 per annum)


  • an Energy Performance Rating (EPC) of E, F or G, or
  • EPC rating of D and the property has either no central heating, is not connected to the mains gas network, has solid walls, is a system built property, has non-standard cavity wall or is a Park Home
  • if no EPC is available, the property must score ’10 or greater’ on the Property Condition Table (pdf 105KB)
  1. To be eligible under the low income and vulnerability to cold criteria, household will need to meet the ‘fuel poverty’ criteria above and will need to have one of the following health conditions:
  • a cardiovascular condition
  • a respiratory condition (ie chronic obstructive pulmonary disease, childhood asthma etc)
  • a mental health condition (moderate to severe)
  • a terminal illness

Has a member living at the household that is one of the following:

  1. Solid wall insulation ‘in-fill’

If your household does not meet any of the criteria set above but you are interested in solid wall insulation (no cavity walls) under this scheme, you may still qualify and would be advised to contact one of the installers listed below.

How do I apply?

We do not provide the ECO funding to eligible householders; it is provided directly by the major energy producers/suppliers to the installers.  There are a number of installing companies working across the district to provide ECO; the names of which are listed below. Each of these installing companies must sign our Memorandum of Understanding (pdf 162KB). 

The installing companies will undertake an initial survey on your property to confirm what measures are needed; assist with the paperwork, submit the relevant documentation to North Devon Council for our approval, provide details of the cost and any contribution you may be required to make eg. in some situations the grant available may be insufficient to cover the full cost of required work.  You may be eligible for a ‘warm up’ grant to assist with these cost (See 'Warm up grants' below).

The contractual relationship is between you (the householder) and the installer.

Please note: We make no recommendation, nor can we endorse any specific company. Inclusion on the list merely indicates that an installer has been approved to work under our SOI (the order of listing shows simply which company applied soonest).

Warm up grants - up to £2,000

These grants, up to a maximum £2,000 per property, provide top up funding for energy efficiency measures where energy providers are part funding energy efficiency measures under their Energy Company Obligation (ECO) or to fund energy efficiency measures which do not attract Energy Company Obligation, for example insulation to mobile homes and the installation of central heating for the first time.

Works will generally include:

  • Mains gas boiler replacement,
  • Loft insulation,
  • Cavity wall insulation,
  • Non-gas boiler replacements,
  • Replacement storage heaters,
  • Internal or external wall insulation,
  • Room in roof insulation,
  • Flat roof insulation


To qualify for the top up grant, applicants must have applied to an installing company under Energy Company Obligation (ECO) Local Flexibility and ECO 3. The installing company will assist with the paperwork and submit the relevant documentation to North Devon Council for our approval.

The grant will normally be paid direct to contractors and no grant will be paid until a satisfactory invoice has been received and the works have been carried out to the satisfaction of the client and council
