ECO4 Grant 2026: Full Guide for UK Homeowners
ECO4 is one of the UK's major energy efficiency schemes. It may help eligible households improve their home through insulation, heating upgrades and other efficiency measures. This guide explains how the scheme works in 2026, who may qualify, and how to check your options.
Energy Checker is an independent guidance website. We are not a government body and we do not approve grant applications. Final eligibility depends on the scheme provider, local authority, installer assessment and property survey.
Quick verdict: who may qualify for ECO4?
- Households receiving certain benefits may be more likely to qualify.
- Homes with lower EPC ratings, poor insulation or inefficient heating may be prioritised.
- Some households not on benefits may still be considered through LA Flex, depending on local authority rules.
This is guidance only and does not guarantee eligibility.
What is the ECO4 grant?
ECO4 stands for Energy Company Obligation phase 4. It is designed to improve the energy efficiency of eligible homes across Great Britain by funding measures that reduce heat loss and lower running costs.
ECO4 may support measures such as insulation, heating upgrades and other energy-saving improvements. It is not a simple cash grant paid directly to homeowners. Work is usually arranged through approved providers and installers, who deliver the measures under scheme rules.
Eligibility depends on household circumstances, property condition and current scheme rules. You can read about other UK schemes in our grants hub.
Who qualifies for ECO4 in 2026?
There are usually two main routes into ECO4: the benefits route and the LA Flex route. You only need to meet one of them, but the property itself also has to fit the scheme criteria.
Benefits route
Households where someone receives certain qualifying benefits may be more likely to be considered for ECO4. Examples often referenced include:
- Universal Credit
- Pension Credit
- Income Support
- Child Tax Credit
- Jobseeker’s Allowance
- Employment and Support Allowance
- Other qualifying support may apply depending on current rules
Low-income and vulnerable households
Households on lower incomes, or with someone vulnerable, elderly, disabled or living with a health condition made worse by cold homes, may also be considered, particularly through the LA Flex route described below.
Property condition and EPC rating
The condition of the property matters. Homes with lower EPC ratings, particularly D, E, F or G, may be prioritised because they have more potential for improvement. You can check your current rating using our EPC rating checker.
Homeowners, tenants and landlords
Owner occupiers, private tenants (with landlord permission) and some social tenants may be considered. Landlords may also be able to access support for eligible properties, subject to scheme rules and provider checks.
The final decision depends on a survey of the property and provider checks. Eligibility is not guaranteed by the routes above, and rules can change between scheme years.
What home improvements can ECO4 cover?
ECO4 typically funds a tailored package of measures designed to make a measurable improvement to the property. Suitability depends on the survey, scheme rules and the provider.
Insulation
- Loft insulation
- Cavity wall insulation
- Solid wall insulation
- Room-in-roof insulation where relevant
The property survey determines suitability.
Heating upgrades
- More efficient heating systems may be considered
- Some homes may be suitable for heat pump-related support
Suitability depends on the property and scheme route.
Solar and renewables
- Some packages may include solar PV where appropriate
- Other renewable measures may be considered case by case
Solar support is not guaranteed. Always check the official scheme or provider details.
You can also estimate potential solar generation and savings using our solar panel savings calculator.
How to apply for ECO4 in 4 steps
The order of these steps matters. Following them in turn helps you avoid pressure tactics and gives you a clearer picture before any work is committed.
- 1
Check your basic eligibility
Consider whether anyone in your household receives qualifying benefits, your approximate income, your EPC rating and the general condition of the property. These are the main factors providers and councils look at.
- 2
Check your EPC rating
Use our EPC rating checker to look up your property’s current rating, or to find out how to obtain one if no certificate exists.
- 3
Use the Energy Checker grant quiz
Take our free grant eligibility quiz. It asks a few short questions about your property and household and shows which schemes may be worth checking, including ECO4.
- 4
Speak to an approved provider or local authority route
A property survey and provider assessment will usually be needed before any work is approved. The provider or local authority will confirm whether ECO4 funding can be applied to your home.
What is the LA Flex route?
LA Flex stands for Local Authority Flexible Eligibility. It can allow councils to identify households that may need support even if they are not on standard qualifying benefits.
- Rules vary by council, so what counts as eligible in one area may not apply in another.
- It may consider low income, vulnerability, health conditions made worse by cold homes, or local criteria set out by the council.
- Each council publishes its own statement describing who it will support.
- Users should check their council route and any specific local rules.

ECO4 scam warnings and what to watch for
The phrase "free government grant" attracts scams. A few practical warnings can help you avoid the most common ones.
- Be cautious of anyone guaranteeing a free grant without checking your details, household circumstances or property condition.
- Be wary of cold callers using pressure tactics, time-limited "offers" or doorstep contracts.
- Do not pay large upfront fees without verifying the company and its scheme route.
- Check installer credentials, including TrustMark, MCS, PAS 2035 and any required certifications.
- Confirm the scheme route in writing, including which obligated supplier or council programme is funding the work.
- Get written information for any quote, contract or eligibility claim before signing anything.
- Check independent reviews and Companies House details for the business.

Frequently asked questions
Who qualifies for the ECO4 grant in 2026?+
ECO4 may be available to households on certain qualifying benefits, lower-income households, vulnerable households and homes with poor energy efficiency. Some households not on benefits may still be considered through the LA Flex route, depending on local authority criteria. Final eligibility is not guaranteed and depends on the scheme provider, local authority, installer assessment and property survey.
Do I need to be on benefits to get ECO4?+
Benefits are a common route into ECO4, but they are not the only route. The LA Flex route may help some households who are not on benefits, where local authority criteria such as low income, vulnerability or a cold-related health condition apply. Rules vary by council and availability is not guaranteed.
Can homeowners get ECO4 funding?+
Owner occupiers may be considered for ECO4 if their household and property meet the relevant criteria. The decision depends on benefits or LA Flex eligibility, the property’s EPC rating, condition and the package of measures the provider can fund.
Can tenants apply for ECO4?+
Tenants may be able to access ECO4 support, but landlord permission is usually needed before any work can take place, particularly for fabric changes such as insulation or heating system upgrades. Speaking to your landlord early in the process is sensible.
Does ECO4 cover solar panels?+
Some ECO4 packages may include solar PV where it is appropriate for the property and the wider energy efficiency plan, but solar is not guaranteed under ECO4. Whether solar is included depends on the scheme route, the provider and the property assessment.
Is ECO4 really free?+
Some measures may be fully funded for eligible households, but support varies and a contribution is sometimes required for certain measures or larger retrofits. Always check the details in writing with the provider before agreeing to any work, and verify the installer’s credentials.
Check if ECO4 may be worth exploring for your home
