ECO4 flexible eligibility statement of intent V1

This version has been superseded by version V1.1

Date of publication: 1st February 2023

version No: V1

This statement sets out Neath Port Talbot County Borough Council's (the Council) flexible eligibility criteria for the Energy Company Obligation (ECO4) scheme (the “ECO4 scheme”) from April 2022 – March 2026.

The ECO4 scheme will focus on supporting low income and vulnerable households. The ECO4 scheme will improve the least energy efficient homes helping to meet the Government’s fuel poverty and net zero commitments.

The flexible approach for Local Authorities (LAs) to identifying fuel poor and vulnerable households who may benefit from heating and energy saving measures is referred to as “ECO4 Flex”.

The Council welcomes the introduction of the ECO4 Flex eligibility routes as it helps the Council achieve its plans to improve the homes of those in fuel poverty or vulnerable to the cold.

The Council is publishing this Statement of Intent (SoI), on the 1st February 2023 to confirm that a household will be declared eligible for the ECO4 scheme if it falls into at least one of the four available routes outlined below:

Route 1: SAP bands D-G households with an gross annual income less than £31,000. This cap applies irrespective of the property size, composition, or region.

Route 2: SAP bands E-G households that meet a combination of two of the following proxies:

  • Proxy 1) Homes in Welsh Provision LSOA 1-3 on the Welsh Index of Multiple Deprivation 2019
  • Proxy 2) Householders receiving a Council Tax rebate (rebates based on low income only, excludes single person rebates).
  • Proxy 3) Householders vulnerable to living in a cold home as identified in the National Institute for Health and Care Excellence (NICE) Guidance. Only one from the list can be used, excludes the proxy ‘low income’.
  • Proxy 4) A householder receiving free school meals due to low-income.
  • Proxy 5) A householder supported by a Council run scheme, that has been named and described by the Council as supporting low income and vulnerable households for the purposes of NICE Guideline.
  • Proxy 6) A household referred to the Council for support by their energy supplier or Citizen's Advice, because they have been identified as struggling to pay their electricity and gas bills.
* Note proxies 1 and 3 cannot be used together.

Route 3: SAP bands D-G households that have been identified by their doctor or GP as low-income and vulnerable, with an occupant whose health conditions may be impacted further by living in a cold home. These health conditions may be cardiovascular, respiratory, immunosuppressed, or limited mobility related. Households under this route can only be referred by an NHS foundation trust, an NHS Trust, a Health Board, a Local Health Board, or a general medical practitioner provider (please request a copy of the NHS referral letter template by emailing NPTCBC at ).

Route 4: SAP band D-G households that are referred under Route 4: Bespoke Targeting. Suppliers and LA’s can submit an application to BEIS where they have identified a low income and vulnerable household, who are not already eligible under the existing routes.

Please note that the ECO4 scheme is not a Council funded or managed scheme, many aspects of it are outside the Council’s control or design.

No liabilities

The Council does not accept any responsibility or liability arising from the consequences, damages or loss whatsoever resulting from the acceptance of an ECO4 scheme grant. This includes efforts connected with the preparation application or survey prior to installation of works, or as a result of works delivered under the ECO4 scheme.

Please note that the Council does not endorse any specific energy supplier, grant agent, installer or company connected to the application or installation of ECO4 scheme grants or products.

Any grievance or issue raised against works or application process related to the ECO4 scheme should be taken up with the installing party/agent / financier. The Council’s involvement in the ECO4 scheme is limited to the declaration of eligibility for ECO4 funding. Should you wish to have the declaration explained in further detail, please email

Final decision

The decision on whether a household receives a measure under flexible eligibility under the ECO4 scheme, or other ECO funding streams will be made by the energy suppliers or their agents/contractors. Qualification in the statement of intent or the signing of a declaration by the Council will NOT guarantee installation of any measures, as the final decision will lie with the supplier.

Whilst some measures being grant-funded will be free to the householder at point of sale, others may be partially grant funded and will require a contribution from the householder or agent in order to be delivered.

Any financial or contractual arrangement relating to the installation of a specific measure or home survey or service shall be at the discretion of the homeowner or occupier to accept or decline as they choose. The Council will not be party to any such arrangements; this shall solely be between the householder and any third party of their choice on the Warm Wales list of approved agents / contractors.


Applications for assessment under this Statement of Intent will need to be made to Warm Wales. The Council will not accept applications directly.
