The short answer: The LA Flex scheme (Local Authority Flexible Eligibility) is the route within ECO4 that lets your local council — not the benefits system — decide you qualify for free insulation and heating, based on low income or vulnerability to a cold home. It runs while ECO4 does, until 31 December 2026. If LA Flex doesn't fit, the Warm Homes: Local Grant is a second no-benefits route for lower-income, privately-owned homes in England (household income usually £36,000 a year or less), running until March 2028. Since the Great British Insulation Scheme (GBIS) closed its GOV.UK referral route on 31 March 2026, these two are the go-to routes for households without benefits.
What is the LA Flex scheme?
"LA Flex" is short for Local Authority Flexible Eligibility — a route within the government's main ECO4 energy-efficiency scheme. Most ECO4 help is benefits-gated (you have to receive a qualifying benefit such as Universal Credit or Pension Credit). LA Flex is the exception: it lets a local council set its own, broader criteria and refer households that would not otherwise qualify. Suppliers are allowed to deliver up to half (50%) of their ECO4 obligation through this flexible route.
Because your council writes the rules, the honest answer to "do I qualify for LA Flex?" is "it depends on your council" — the income limits and qualifying conditions genuinely differ from one area to the next. Below is exactly how LA Flex works, who it's for, and how it compares with the Warm Homes: Local Grant, the other no-benefits route.
"I don't get benefits — can I still get a grant?"
This is the most common question we get, and since GBIS closed it has only become more common. Most of the headline energy-grant schemes — like the main ECO4 route — are benefits-gated. GBIS used to be the obvious answer for everyone else, because it qualified households by council tax band rather than income. With the GBIS GOV.UK referral route now closed to new applicants, that gap is filled by two council-run routes: the LA Flex scheme and the Warm Homes: Local Grant.
The good news: both are designed specifically for people who don't claim benefits but are still on a modest income or living in a hard-to-heat home. They just work differently from a national scheme — your local council is in the driving seat.
Quick comparison: the two no-benefits routes in 2026
| ECO4 LA Flex | Warm Homes: Local Grant | |
|---|---|---|
| What it is | A flexible route within ECO4 where councils set their own eligibility criteria | A government grant delivered by councils for low-income, energy-inefficient homes |
| Who it's for | Households in fuel poverty or on a low income and vulnerable to a cold home — no benefits needed | Lower-income households in privately-owned or privately-rented homes in England |
| Income test | Set locally by your council (published in its "Statement of Intent") | Household income usually £36,000/year or less (with some alternative pathways) |
| Home type | Private tenure only (owner-occupier or private rental; social housing excluded) | Privately owned or privately rented; England only |
| What it covers | Insulation and heating measures under ECO4 | Insulation and low-carbon heating upgrades |
| Runs until | 31 December 2026 (ECO4's final year — funding is limited) | March 2028 |
| Who decides | Your local council + an obligated energy supplier | Your local council |

ECO4 LA Flex: how "flexible eligibility" works
ECO4 is the government's main energy-efficiency scheme, funded by an obligation placed on large energy suppliers (it is not paid for out of your taxes, and it is free to the household). Most ECO4 help goes to people on qualifying benefits — but suppliers are allowed to deliver up to half of their obligation through the LA Flex route.
Under LA Flex, your local council can refer private tenure households it considers to be:
- living in fuel poverty, or
- on a low income and vulnerable to the effects of living in a cold home.
Crucially, you do not need to be on benefits. Each council publishes a document called a Statement of Intent that sets out the exact income levels, health conditions, and other criteria it will use. Because every council writes its own, the rules genuinely differ from one area to the next. The typical income thresholds and qualifying health conditions are set out below.
Who and what is eligible:
- Tenure: private only — owner-occupiers and private renters (with landlord consent). Council and social housing are excluded from flexible eligibility.
- Property: your home usually needs a lower EPC rating (typically D–G) showing it needs the improvement.
- Measures: insulation (loft, cavity wall, and more) and heating measures, depending on what your home needs and what your supplier will fund.
Timing note: ECO4 — and the LA Flex route within it — runs until 31 December 2026 (ECO4 was extended to this date). As this is the scheme's final year, supplier funding is limited and being used up, so if LA Flex is your route it's worth checking sooner rather than later.
LA Flex income thresholds and qualifying conditions
Because each council writes its own Statement of Intent, there are no national LA Flex income limits — the figures below are typical planning benchmarks used by many councils, not fixed national rules. Always confirm the current criteria with your own council.
| Household type | Typical income threshold |
|---|---|
| Single adult | £20,000 – £25,000 |
| Couple with no children | £25,000 – £30,000 |
| Family with children | £30,000 – £35,000 |
| Household with a disability or health condition | Higher thresholds often apply |
Many councils also qualify households on health grounds — where a cold home would make a medical condition worse. Conditions councils commonly include are:
- Respiratory conditions (for example asthma or COPD)
- Cardiovascular conditions
- Diabetes
- Arthritis and limited mobility
- Mental health conditions affecting daily living
- Conditions affecting the body's temperature regulation
- Terminal illness
Even if your condition isn't on this list, you may still qualify — each council sets its own. Councils may also weigh up your property (typically an EPC rating of E, F or G), your council tax band (some use bands A–D in England as a proxy), and circumstances such as being a carer, a veteran, or a young person leaving care. The exact evidence you'll need — payslips, bank statements, or a letter from your GP — is set by your council.
Warm Homes: Local Grant — the longer-running route
The Warm Homes: Local Grant is a separate government scheme that runs from April 2025 to March 2028 — so it has the longest runway of any current route. Local authorities deliver it in their areas, managing applications and arranging the home survey and the work. Read our dedicated Warm Homes: Local Grant guide for the full detail.
Who it's for:
- Lower-income households — income is usually £36,000 a year or less, though some councils accept alternative qualifying pathways (for example, a qualifying postcode or a household member on certain benefits) if you're just over the threshold.
- Privately-owned or privately-rented homes in England that are energy-inefficient (an EPC rating of D–G).
What it covers: energy-efficiency improvements (such as wall, loft and underfloor insulation) and low-carbon heating upgrades like air source heat pumps, aimed at cutting bills and improving warmth in homes that are expensive to heat.
Because it's income-based rather than benefits-based, the Warm Homes: Local Grant is often the right answer for working households who don't claim benefits but are still feeling the squeeze.
Which route is right for you?
A simple way to think about it:
- Private homeowner/renter on a modest income, no benefits → start with your council's LA Flex criteria (it can cover both insulation and heating, but funding is limited in ECO4's final year).
- Lower-income household (income roughly £36k or under) in a privately-owned home in England → the Warm Homes: Local Grant is likely your best long-term route (open to 2028).
- You DO claim a qualifying benefit (Universal Credit, Pension Credit, and others) → you may qualify for mainstream ECO4 — see our ECO4 scheme guide and ECO4 eligibility guide.

How to apply for the LA Flex scheme (step by step)
- Check your eligibility using the checker above, or look up your council's ECO4 Flexible Eligibility "Statement of Intent" and its Warm Homes: Local Grant page.
- Get matched to a route and an installer — for LA Flex this means a participating energy supplier; for Warm Homes it's your local authority's delivery partner.
- Home survey — an assessor visits to confirm what measures your home needs and that you meet the criteria.
- Installation — the work is carried out by certified (TrustMark-registered) installers at no cost to you under these routes.
- EPC update — your Energy Performance Certificate is updated to reflect the improvement.
What happened to GBIS?
The Great British Insulation Scheme (GBIS) closed its GOV.UK referral route to new applicants on 31 March 2026. It was the scheme that qualified households by council tax band (A–D in England) rather than by benefits, so its closure mainly affects people without benefits — exactly the group the LA Flex scheme and Warm Homes are designed for. If you were counting on GBIS, those two routes are where to look next. For the full picture, see our Great British Insulation Scheme — what to check next guide and our free insulation grants overview.
