A UK household needs to meet certain income or health conditions criteria to qualify for the LA flex scheme. Local authority flexible eligibility is an extension of the ECO4 scheme that allows local councils to fund heating solutions for those not on benefits.
LA flex entertains almost 4 routes and several proxies. We will be discussing the main 2 of them. For the rest of 2, you may need to contact your local council. So, get excited and bring your positive energy forward as we dig deeper into the details.
Major Eligibility Routes Under LA Flex
Most homeowners are usually hyper-fixated on benefits eligibility, and they often don’t think to explore other possibilities. Below are some of the most common and popular LA flex routes through which thousands of households are getting heating solutions.
Route 1 – Lower Household Income
If your household’s income is below £31,000/annually, and the EPC rating of your home is E or lower, you can directly qualify through route 1 of LA flex. That’s the total household income, everyone who lives at your address. Count wages, pensions, self-employment profits, and rental income.
One mistake kills applications: forgetting to include your partner’s income. Councils cross-check against Council Tax records. Underreporting = instant rejection.
Route 3 – Do You Have a Health Condition Made Worse by Cold?
Cold homes make people sick. If you’ve got a medical condition that worsens in the cold, income doesn’t matter; you qualify automatically.
Eligible conditions include:
- Respiratory diseases (asthma, COPD, bronchitis)
- Cardiovascular problems
- Mobility issues or disabilities
- Cancer, dementia, severe mental illness
- Diabetes, autoimmune conditions
The catch? You need clinical proof. A GP letter that says “cold temperatures aggravate Mr Smith’s COPD” works. A vague “Mr Smith has breathing problems” doesn’t. Get specific. Get clinical language.

What Documents Actually Get You Approved
Weak paperwork gets rejected. Period. Gather these before contacting an installer:
Everyone needs:
- Proof of residence (Council Tax bill or tenancy agreement + landlord permission)
- Proof of income (3–6 months of payslips, pension statements, or business accounts)
- Recent energy bill
- Photo ID for all adults
Health route applicants add:
- GP letter linking cold to your condition
- Hospital records showing cold-related incidents
- NHS specialist letters with clinical detail
Self-employed? Don’t send estimates. Submit actual profit figures from your accountant or HMRC tax returns. Councils don’t trust guesses.
Renters need written landlord permission. Email confirmation works fine, just get it in writing.
The Application Process: Who Does What
You don’t apply to your council directly. Here’s the actual workflow:
- Find a TrustMark-approved ECO4 installer in your area
- They conduct a home survey (usually a new EPC or RdSAP assessment)
- They collect your documents and verify eligibility
- They submit to the energy supplier under the LA Flex route
- Your council reviews and approves (or rejects) the application
Timeline? Four to eight weeks typically. Busy councils take longer. High-demand areas sometimes hit twelve weeks.
Why not go to the council first? Because they don’t process applications, installers do. The council only approves what installers submit.
What Improvements Do You Actually Get?
Once approved, you receive free energy upgrades. No partial funding. No cost sharing. Fully funded.
Standard measures:
- Loft insulation (up to 270mm depth)
- Cavity wall or solid wall insulation
- Underfloor insulation
- Full heating system replacement
- Air source heat pumps
Some councils also fund:
Solar PV panels
- Battery storage systems
- Smart heating controls
The goal? Improve your EPC rating to at least a D, ideally a C. Installers recommend measures based on your home’s current state and what makes the biggest impact on heat retention.
No funding caps exist officially, but realistic projects range from £3,000 (basic loft and cavity work) to £20,000+ (solid wall insulation and heat pump installs).
The Final Word
The LA flex is the most thoughtful government initiative to address lower energy efficiency and higher energy costs. Households should take it like one, complete the proper documentation, and then apply through proper channels.
Most households treat it like a lottery and think they don’t need to prepare the documents or apply like they need to. While applying through Installers like Grant Boilers might ease the process, they still need to do the basics right.
Frequently Asked Questions
Yes. That’s the entire point of LA Flex. Standard ECO4 requires benefits. LA Flex uses income instead. Working households on £30,000 qualify just as easily as benefit claimants.
They’re either not participating or haven’t opened applications yet. Contact them directly or ask an ECO4 installer about their status. No SoI = no LA Flex in that area.
No. But you need their written permission to proceed. Most landlords say yes, it’s free property improvement for them. Document everything in writing.
Use your average annual profit from tax returns or accountant-prepared accounts. Councils prefer audited figures over self-reported estimates.
Three main reasons: missing documents, income over the local threshold, or your home already received ECO funding recently. Request specific feedback and reapply if circumstances change.
