ECO4 Flex Scheme offers UK homeowners a powerful opportunity to access fully funded energy efficiency upgrades even if they don’t receive government benefits. Through LA Flex grants, local councils can approve households based on income, health conditions, or local needs, ensuring more families can benefit from upgrades such as free boiler replacements, central heating systems, insulation, and air source heat pumps. This flexible approach allows councils to target homes most at risk of fuel poverty, helping residents reduce energy bills while improving comfort and home efficiency.

The Energy Company Obligation (ECO) is a government energy efficiency scheme run by Ofgem. This scheme is now in its 4th phase and is expected to run till 31 March 2026. The delivery of the flex scheme is supported by local authorities.

To access support through the ECO4 Flex Scheme, your home must meet certain energy efficiency standards. In most cases, the property should have an EPC rating of D, E, F, or G, as these homes are considered less efficient and more likely to benefit from government-funded improvements. If your home has an EPC, you can view it online through the official Government EPC register.

Along with the property requirements, households must also meet at least one eligibility condition set by the council. You may qualify if:

• Your total household income is £31,000 or below,

• You have a health condition negatively affected by cold living conditions (for example: respiratory issues, cardiovascular problems, limited mobility, or weakened immune system),

• Or your local authority identifies your home as vulnerable or at risk of fuel poverty, even if you don’t meet standard ECO4 criteria.

If eligibility is based on a medical condition, income thresholds are not applied, making it easier for vulnerable residents to receive support. Once you apply, an approved installer will carry out a home survey to confirm suitability and determine which measures such as insulation, heating upgrades, or a boiler replacement can be funded under the scheme.

LA Flex Scheme is an extension of the Government ECO4 Scheme, created to help households who need support but don’t qualify through the standard benefits-based route. Instead of relying solely on government benefit criteria, LA Flex gives local UK councils the authority to set their own eligibility rules. This allows councils to approve applications based on real local needs and priorities, ensuring support reaches more vulnerable or financially stretched households. Councils can define eligibility criteria such as:

• Low Income below 31k income.
• Health Condition.

Energy Company Obligation (ECO4) is a government-backed Scheme designed to reduce carbon emissions and help low-income and vulnerable households stay warm by improving home energy efficiency. Through the ECO4 Flex Scheme, local councils are given the freedom to set their own eligibility criteria, making it possible for households that are not on traditional qualifying benefits to still receive support. This flexible route is especially useful for residents who may be struggling with high energy costs, have health conditions affected by cold living conditions, or live in homes with poor EPC ratings.

ECO4 Flex funding is available only to private homeowners and private rented properties, giving many residents a route to essential upgrades such as a free boiler replacement, central heating system, insulation, or heating controls. If you receive benefits like PIP (Personal Independence Payment) or Attendance Allowance, you may have an even stronger case to qualify especially when applying through your local council’s flexible eligibility process. Councils publish a Statement of Intent outlining who they can support, and approved installers must follow these guidelines before carrying out work in each local authority area. This ensures that households most in need get access to government-funded energy upgrades while the scheme is still available.

Great British Insulation Scheme (GBIS) is a government-backed programme overseen by Ofgem, designed to help households improve their home’s energy efficiency through affordable insulation upgrades. The scheme is currently scheduled to run until 31 March 2026, giving homeowners and private tenants a limited window to benefit from the available support. Under the GBIS Flex route, local authorities can assist in identifying households that may qualify based on income, vulnerability, or poor energy performance.

Through GBIS Flex, eligible properties can receive funding toward a single, suitable type of insulation, such as loft insulation, cavity wall insulation, or other approved measures. In some situations, the homeowner or landlord may be asked to contribute toward part of the installation cost, depending on the property type and the measure required. By working with your local council and an approved installer, households can access essential insulation upgrades that help reduce heat loss, lower energy bills, and make homes warmer and more efficient.

To qualify for support under the GBIS Flex Scheme, your home must typically have an EPC rating between D and G, as these properties are considered less energy efficient and most in need of insulation improvements. Alongside the property requirement, households must meet at least one of the criteria set by the local authority.

You may be eligible if:

• Your combined household income is £31,000 or below,

• A medical professional has identified that you have a health condition made worse by cold or inefficient housing—such as respiratory issues, cardiovascular problems, mobility limitations, or a weakened immune system,

• Your property falls within Council Tax bands A–D, which often represent lower-value homes more likely to benefit from insulation support.

If you meet one or more of these conditions, you may be able to receive funded insulation measures through the GBIS Flex scheme, subject to a property survey and final approval.

The LA Flex Scheme offers a range of advantages for households that need support improving their home’s energy efficiency. One of its biggest benefits is that eligible homeowners pay nothing, as installation, equipment, surveys, and compliance checks are covered through government-backed funding. By upgrading to modern heating systems and insulation, households can enjoy lower monthly energy bills, improved warmth, and a safer home environment particularly important for residents with health conditions affected by cold temperatures.

The scheme also plays a key role in supporting the UK’s long-term carbon reduction goals by helping homes use less energy and operate more efficiently. Most importantly, LA Flex opens the door for households not receiving benefits to still access free energy improvements, offering a fairer route to essential upgrades such as boiler replacements, central heating, insulation, and heat pumps.
