Building a Greener Future with the Eco-Flex Scheme

Discover how the Eco-Flex Scheme revolutionizes how councils support vulnerable households in achieving energy efficiency. This innovative approach allows local councils to customize their ECO4 funding, reaching out to those who need it most and ensuring that no household is left behind in the journey towards sustainability.

The Eco-Flex Scheme empowers councils to adapt the ECO4 criteria to fit the unique needs of each household. This flexibility means that families and individuals who might not have qualified for energy efficiency upgrades under traditional rules can now benefit. 

The scheme promotes energy efficiency and fosters equitable access to sustainable living solutions by focusing on those in the greatest need.

Join us in exploring how the Eco-Flex Scheme is paving the way for a greener, more inclusive future.

What Is ECO4 Scheme?

ECO4, the fourth iteration of the Energy Company Obligation scheme, is a government initiative in England, Scotland, and Wales to cut carbon emissions and address fuel poverty. This scheme focuses on enhancing home energy efficiency for those most in need.

Primarily, ECO4 offers financial support for insulation and heating improvements, targeting the UK’s fuel-poor and vulnerable households. Key interventions include installing internal wall and loft insulation and replacing outdated boilers.

Through ECO4, energy companies are mandated to implement these carbon-reducing measures in the homes of low-income families or those experiencing fuel poverty. The scheme largely finances these upgrades, covering most of the costs involved.

What Is The Eco-Flex Scheme?

The ECO4 Flex Scheme, also known as the Local Authority Flex Scheme, is a vital component of the government’s ECO4 program designed to extend its funding reach. To qualify for the standard ECO4 funding, applicants must receive certain government benefits.

However, ECO4 Flex addresses this limitation by catering to a broader range of low-income households in the UK that would otherwise be ineligible for the grant.

This scheme operates as a referral system within the ECO4 framework, enabling Local Authorities and Councils to expand the eligibility criteria for accessing ECO4 funds. By adjusting these criteria, each Local Authority can offer ECO funding and energy-efficient initiatives that are specifically tailored to the needs of their area and community.

Under the ECO4 Flex Scheme, Local Authorities can refer private tenants who are considered fuel-poor, have a low income, or are vulnerable to the health impacts of living in a cold home. 

This inclusion offers access to ECO4 energy efficiency grants and funding for those in the private rental sector, a group that typically would not qualify under the standard criteria.

What Does The Eco-Flex Scheme Aim For?

The primary goal of the ECO4 Flex scheme is to offer the 12.6 million UK households possessing an Energy Performance Certificate rating of D or lower the chance to enhance their property’s energy efficiency.

This initiative not only aids UK residents in upgrading their homes and reducing their energy costs but also broadens the eligibility scope. Such an expansion in eligibility helps suppliers meet the obligation targets by April 1, 2026.

Do I Qualify For The Eco-Flex Scheme?

Understanding if you qualify for ECO4 Flex funding involves considering several key factors. Firstly, to be eligible for this government ECO funding, you must be a UK resident residing in a property rated D or lower on the Energy Performance Certificate scale.

Furthermore, your eligibility hinges on whether your Local Authority has opted into the LA Flex program. This includes publishing a statement of intent on their website and communicating a declaration notification to Ofgem.

Let’s delve into the four pathways to access Local Authority ECO4 funding.

1: Household Combined Income Route

Under this method, you may be eligible for ECO4 Flex if your household’s gross income is £31,000 or less. This includes the income of all household residents aged 18 and over, such as elderly inhabitants and lodgers. 

You can use the latest year’s tax return, P60, annual income pension statement, a P45 from the past three months, or the most recent three payslips to prove this income. 

The number of people living in the residence can be verified through tenancy agreements, council tax letters, soft credit checks, electoral registers, or mortgage statements.

2: Proxy Targeting

If your home falls within the E, F, or G bands on the Energy Performance Certificate (EPC), you may qualify for ECO4 Flex funding. To be eligible, your household should fulfill at least two of the following criteria:

  • Residing in an area ranked 1-3 on the Lower-layer Super Output Area (LSOA) scale, or equivalent in Welsh and Scottish measures of multiple deprivation.
  • Receiving a rebate on Council Tax.
  • Being vulnerable to the health impacts of living in a cold home.
  • Qualifying for free school meals due to low income.
  • Receiving support from a Local Authority program for low-income or vulnerable households.
  • Referral for support from Citizens Advice, Citizens Advice Scotland, or an energy supplier due to difficulties managing energy bills.
  • Identification through energy supplier debt data as a household in need.

3: NHS Referrals Route

This option is for residents with long-term or severe health conditions, such as limited mobility, respiratory diseases, immunosuppression, or cardiovascular issues. 

Eligibility must be supported by a referral letter from someone within the NHS Trust, NHS Trust Board, or the General Practitioner Register.

4: Bespoke Targeting Route

This final method is for those unable to qualify through the other three routes but still face challenges with energy-inefficient homes. Applicants can submit a proposal for consideration to the Department for Energy Security and Net Zero (formerly BEIS). 

Each proposal is reviewed by a BEIS panel, which determines the property’s eligibility for ECO4 Flex funding.


In conclusion, the ECO4 Flex scheme offers a lifeline for UK households struggling with energy efficiency. Its flexible criteria and multiple eligibility routes ensure that energy-saving upgrades are accessible to a broader range of people, reducing energy costs and promoting sustainable living.
