The Greater London Authority has made it possible for interested property owners and renters, as well as eligible households who are in need to install insulation or upgrade their heating while earning ECO grant funding from the government.
A set of rules have been published on the council’s Statement of Intent which will allow you to apply for these funds too.
1. What is Local Authority Flexible Energy or LA Flex?
2. What grants are available?
The types of grants available to residents living in the Greater London Authority 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. Who is eligible for grants?
Renters, homeowners and living in a housing association have a great chance for the grant. 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
A medical practitioner will need to complete a referral form 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.
People with health conditions that are made worse by living in a cold home qualify.
These include:
- Cardiovascular diseases
- Immunosuppressed
- Mobility issues
- Respiratory conditions
A medical practitioner will need to complete a referral form 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.
Installers can target specific groups of people living in fuel poverty. Installers will approach you if your property is eligible through this route.
Greater London Authority
If you DON'T claim benefits, the criteria for identifying households in fuel poverty in Greater London Authority are as follows:
Criteria for Greater London Authority eligible households
Low income and vulnerability to cold
I. Aged over 60, and particularly those over 75
ii. Children under S and pregnant mothers

Fuel Poverty
- We will work with London boroughs and other partners to promote our fuel poverty programmes to Londoners in greatest need
- Individuals in fuel poverty will be identified through our regional fuel poverty referral network and other fuel poverty projects operating in London
- We will work with Gas Distribution Networks to reach vulnerable off-gas households
- Our own data has highlighted those lone parents and members of Black, Asian and minority ethnic (BAME) communities are at greater risk of fuel poverty and we will target these groups

5. How much could you get?
One of the first things you should probably do when trying to get a grant is figuring out your heating situation. This will depend on how much warmth or heat you need and what type of property it’s in as well as whether there are any grants available for that area.
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

The grant is given to the registered installer, without repayment. They’ll be happy to explain this upfront and provide an estimate as they can do so with no questions asked. If you want a cost breakdown before installation, ask your installer about it – all while making sure there are never any hidden fees or costs on top too! A free survey will tell if any grants available that cover your needs.
