If you’re worried about your energy bill, the London Borough of Bexley Council may be able to help with ECO grants. Residents can apply for Bexley insulation grants and other heating measure to save money on their bills while simultaneously helping the environment!
1. What is the Bexley Insulation Grant Scheme? ECO4 LA Flex Explained
The London Borough of Bexley Council has a flexible energy policy that allows residents to apply for Energy Company Obligation (ECO) grants! Whether you need heating system repairs, upgrades or insulations, the ECO grant is available and could help save money in your pocket.
The Statement of Intention written by councillors provides detailed guidance on how residents can qualify for these funds. This post will explain which eligibility requirements are needed before applying for an ECO Grant.
2. What grants are available?
The types of grants available to residents living in the London Borough of Bexley Council area include:
- Boiler grants
- Cavity wall insulation grants
- External wall insulation grants
- First time central heating grants
- Internal wall insulation grants
- Loft Insulation
- Roof Insulation
- Smart thermostat grants
- Underfloor insulation grants
Boiler grants are expected to be removed from the grant scheme in the next phase so you should apply for this grant as soon as possible.
3. Eligibility for Bexley Insulation Grants: Do You Qualify?
You will be able to benefit from the program even if you are a homeowner, living in a housing association, a tenant, and a renter! The easiest way to see if you are eligible is to use our eligibility checker here.

Eligibility
There are 6 ways to qualify for a grant:
1. Receiving a qualifying benefit
2. Receiving Child Benefit and meeting income rules
3. Income-based eligibility (for households that earn less than £31,000 per year)
4. Vulnerable eligibility
5. Health-related eligibility
6. Bespoke targeting
This route to eligibility applies where a member of the household receives or has received a 'qualifying benefit'. If the benefit isn't a current claim (for example for households where they have gone back to work after the pandemic) providing the benefit has been claimed at some point within the last 12 months, the household will still be eligible for a grant.
Qualifying benefits include:
- Child Tax Credit
- Employment & Support Allowance (Income Based) - Income Support
- Housing Benefit
- Jobseekers Allowance (Income Based)
- Pension Credit Guarantee Credit
- Pension Credit Savings Credit
- Universal Credit
- Working Tax Credit
Note if you receive any of the following benefits you could qualify later in the scheme (or through the ECO4 Flex routes). We advise anyone claiming the following benefits to register for updates so you are the first to know when these benefits are accepted.
- Armed Forces Independence Payment
- Attendance Allowance
- Carer's Allowance
- Constant Attendance Allowance
- Disability Living Allowance (DLA)
- Industrial Injuries Disablement Benefit
- Personal Independence Payment (PIP)
- War Pensions Mobility Supplement
If you receive Child Benefit you could be eligible for the scheme but unlike the qualifying benefits above they would need to meet an additional income criteria.
The Child Benefit income criteria depends on the number of children in the household and also whether the claim is a single or joint claim.
The income limits are as follows:
Single parents
1 Child – £19,900
2 Children – £24,800
3 Children – £29,600
4+ Children – £34,500
Parents in a couple
1 Child – £27,500
2 Children – £32,300
3 Children – £37,200
4+ Children – £42,000
(figures updated to Ofgem’s Administration Consultation released on 13 June 2022)
If you are eligible through the Child Benefit route you should apply as soon as you can. The Government's Green Homes Grant excluded Child Benefit recipients so potentially this eligibility route could be removed later in the the scheme.
To be eligible through the income-based route your annual household income will need to be under £31,000. You will need to provide evidence such as bank statements and income information to confirm eligibility.
This is an ECO4 Flex route so it requires the applicants council to have published a Statement of Intent and to issue eligibility declarations.
Vulnerable people can access grants if they meet two of the following criteria (1 & 3 can’t be used together):
1. Lives in a Lower Super Output Area
2. Receives Council Tax Rebate (excluding for single person discounts)
3. Householder has a disability, mental health condition, is over 65, school children or under 16 and pregnant women.
4. Receives free school meals due to a low income
5. Supported by a Council scheme described in a Statement of Intent
6. Households referred by a Citizen’s advice as struggling to pay gas and electricity bills
7. Households in energy debt

4. How much could you get?
Bexley Borough Council wants to make sure that residents are able and willing to save money by using energy more efficiently. One way is for you to get a grant through ECO, which will pay part of the cost. Whether you need heating repairs or upgrades, insulations or anything else – be on the lookout. You might just find yourself with some extra cash in your pocket each month for saving on energy bills and saving the environment!
The grants are currently available as follows (subject to survey and meeting eligibility rules):
- Boiler grants - this could give you 25% - 75% off the RRP of installing a new boiler
- Cavity wall insulation grants - up to 100% of the installation cost
- External wall insulation grants - up to 100% of the installation cost (only available where electric is the main heating source)
- First time central heating grants - 50-100% of the installation cost (propeties must not have previously had central heating)
- Internal wall insulation grants- up to 100% of the installation cost (only available where electric is the main heating source)
- Loft Insulation - up to 100% of the installation cost (usually only available where electric is the main heating source but in some areas loft insulation is available for gas properties)
- Roof Insulation - up to 100% of the installation cost (usually only available where electric is the main heating source but in some areas roof insulation is available for gas properties where it is installed alongside a new boiler)
- Smart thermostat grants - up to 100% of the cost but only available through some installers
- Underfloor insulation grants - up to 100% of the installation cost but usually only installed alongside another measure like a boiler upgrade

These days, it’s so easy to get the installation your home needs with help from a grant. You won’t have any worries about repayment either because you’ll be dealing directly with registered installer who quotes costs upfront too! They can also answer questions on what funding may be available when conducting surveys of homes and provide advice for many different situations.
