The LA Flex scheme is one of the easiest ways households can qualify to get free heating upgrades under the ECO4 scheme. It’s designed to help low-income and vulnerable households access heating support, even if they don’t receive government benefits. For many people, the Local Authority Flexibility becomes the route to getting free boilers, first time central heating systems, heat pumps, electric storage heaters, or insulation upgrades that would otherwise cost thousands of pounds.
However, not every application is approved under it, despite being flexible. Before approving a household under LA Flex, the local authorities have to follow strict guidelines. This results in many applications either getting delayed or being completely rejected.
This article will outline the most common reasons why LA Flex grant applications get rejected, how to avoid them, and what you can do in case you believe you still qualify.
Income Proof is Either Missing or Incorrect
Under Route 1 of LA Flex, low-income households can qualify when total annual income is less than £31,000.
However, applications are commonly rejected because the income proof:
- is incomplete.
- does not cover all adults living in the home.
- uses outdated or mismatched documents.
- does not include other types of income, like pensions, rental income, or maintenance payments.
Important rule
Councils calculate gross household income, not just the applicant’s income.
Examples of income-related mistakes:
- Only the applicant’s payslip was submitted despite other household members working.
- Bank statements do not match the declared amount.
- Self-employed income is not correctly documented.
How Can You Avoid Rejection
Provide:
- three months of recent bank statements
- recent payslips for all working adults in the household
- proof of any benefit, top-ups, pensions, or tax credits
- a declaration form for council-approved incomes
Above all, clarity and accuracy are what matter the most.
The Property Does Not Meet EPC Requirements
One of the main reasons LA Flex gets rejected is due to not meeting EPC rules. Most councils require the home to have an EPC rating of E, F, or G to qualify for ECO4-funded upgrades. Homes with EPC A, B, or C are usually considered energy-efficient enough and therefore do not meet the criteria of fuel poverty risk.
Why this matters:
ECO4 and LA Flex exist to support homes that:
- are expensive to heat
- waste energy
- significantly contribute to carbon emissions
You are not considered a priority household if your EPC rating is too high.
Common EPC-related issues
- There is no recorded EPC for the property.
- The EPC is outdated and does not reflect the current condition of the home.
- Past home improvements have increased the EPC rating above C.
How Can You Avoid Rejection
- Check your EPC for free online.
- If no EPC exists, arrange a new assessment before applying.
- If you believe the EPC is incorrect, request a reassessment.
Medical Evidence Is Too Weak (Route 3 Rejections)
Route 3 (Health & Medical Conditions) enables councils to refer households where someone has a condition made worse by living in a cold home.
However, this is the most commonly rejected category because evidence is often:
- vague
- incomplete
- outdated
- not clearly linked to cold home risks
Medical conditions commonly accepted are:
- Cardiovascular disease (coronary heart disease, stroke)
- Respiratory conditions (COPD, asthma)
- Limited mobility (arthritis, etc.)
- Immunosuppression (cancers, autoimmune disorders)
Typical reasons for rejection
- A GP letter that does not mention the home environment
- Outdated medical records (older than 12 months)
- Self-reported medical conditions without supporting documentation
How Can You Avoid Rejection
You should collect:
- a recent GP or consultant letter
- evidence of repeat prescriptions
- hospital discharge notes (where applicable)
- documentation linking the condition to cold or damp home conditions
Your evidence must clearly explain the link between your health condition and the need for home heating improvements.
Landlord or Property Ownership Issues
Tenants can apply under LA Flex, but this requires landlord permission. Many applications are refused because:
- the landlord does not respond.
- the landlord refuses consent.
- the property is not legally registered.
- the landlord has outstanding enforcement issues with the council.
How to Avoid Rejection
- Inform your landlord early.
- Obtain written consent before the installer carries out the survey.
- Ensure the property has no outstanding local authority enforcement notices.
The Home Already Received ECO Funding Recently
The other major reason for rejection is when the property has already had work completed under ECO2, ECO3, or earlier ECO4 phases.
Why does this lead to rejection?
ECO rules prevent double funding for similar measures.
For example:
- If you have already received insulation, you cannot receive the same measure again.
- If your boiler was upgraded under a previous scheme, it cannot be replaced again under ECO4.
How Can You Avoid Rejection
- Check your property’s history using the Ofgem ECO public database.
- Inform your installer if your home has previously received government-funded energy upgrades.
The Property Is Not Suitable for the Proposed Measure
Not all homes are suited for heat pumps, insulation, or boiler upgrades. Many rejections are due to:
- structural problems
- severe damp
- roof damage
- unsafe electrical systems
- poor ventilation
Space limitations
- no suitable outdoor space for an air source heat pump
- lofts with insufficient depth for insulation
- wall types incompatible with cavity insulation
- planning permission restrictions
Listed buildings
- Conservation areas
- Flats or maisonettes sharing common external walls
- Park homes
How Can You Avoid Rejection
- Fix any property issues before applying.
- Provide access for proper surveys.
- Confirm with installers whether your home is suitable.
The Landlord Does Not Approve (For Tenants)
Private tenants can apply under LA Flex, but only where the landlord authorises this.
Landlords usually refuse such upgrades because:
- They do not want external changes to the property.
- They intend to sell the property.
- They do not wish to commit to future safety checks.
- They misunderstand the scheme or believe they must pay.
How Can You Avoid Rejection
- Explain clearly and politely that ECO4 upgrades are free.
- Provide documentation confirming there is no cost to the landlord.
- Highlight potential property value increases and EPC improvements.
One of the most common reasons tenant applications fail is a landlord refusing consent.
Incomplete/Incorrect Details Related to an Application
Many applications are unsuccessful because of numerous minor but serious errors, including:
- Wrong contact information
- Wrong address
- Missing National Insurance numbers
- Mismatched names on documents
- Failure to submit all required forms
- Skipped questions
- Unreadable document scans
Because LA Flex involves councils, installers, and Ofgem, even one missing detail can result in complete rejection.
How Can You Avoid Rejection
- Fill out forms slowly and carefully.
- Use high-quality scans or photos.
- Double-check names, dates, and addresses.
Ask your installer to review documents before submission.
Your Local Council Is Not Participating in LA Flex
Not all councils offer Local Authority Flexibility.
Your property may qualify perfectly, but if your local authority has:
- paused the scheme
- exhausted its LA Flex funding
- limited its local eligibility rules
- not signed a declaration with your installer
…your application will be rejected.
How Can You Avoid Rejection
Before applying, check:
- whether your council currently participates
- which installers they work with
- whether your area’s LA Flex is open or paused
This changes frequently, so always check the current status.
The Installer Is Not Approved for LA Flex Submissions
Only registered ECO4 installers can submit LA Flex applications. Rejections occur when:
- A non-approved installer submits the job.
- Documents do not meet Ofgem standards.
- The council’s local eligibility rules are not followed by the installer.
- Survey reports do not meet the required technical standards.
How Can You Avoid This
Select an installer who is:
- Ofgem-approved
- Registered under PAS 2030 or MCS (for heat pumps)
- Experienced with council referrals
Working with the wrong installer is one of the fastest ways to get rejected.
The Funding Allocation Has Run Out
Even if you qualify perfectly, LA Flex is limited by:
- council budgets
- installer capacity
- seasonal demand
- limitations on national funding
And when the funding runs out, the councils have to refuse applications or put them on hold.
How Can You Avoid This
- Apply early in the financial year
- Respond promptly to installer calls and emails
- Book your survey as soon as possible.
The Upgrade Will Not Reduce Enough Carbon (ECO4 Rules)
This is a technical but common reason for rejection. Under ECO4 Scheme, every property must show a minimum SAP score improvement to receive funding.
Ofgem can also reject a measure if the selected upgrade does not raise your property’s EPC/SAP score enough.
Examples:
- Installing loft insulation in a home that already has enough.
- Installing a heat pump in a severely under-insulated property.
- Replacing a boiler that does not achieve sufficient SAP gain.
How Can You Avoid This
Your installer must perform a pre-installation SAP assessment to determine which measures actually qualify.
What to Do If Your Local Authority Flexibility Application Is Rejected
A rejection doesn’t mean you’re out of options. Here’s what you can do:
- Ask them for an exact reason.
- Most rejections are simple to fix.
- Provide missing documents.
- Quickly resubmit the necessary paperwork.
- Request a second EPC.
If the problem was EPC, a fresh assessment might result in a different rating.
Try Another Route
If you don’t qualify under LA Flex, you may qualify through:
- Standard ECO4 benefits route
- Great British Insulation Scheme (GBIS)
- Boiler Upgrade Scheme (BUS)
Re-apply if circumstances change. A new EPC, updated income, or better medical evidence could help with approval.
How to Improve Your Chances of Approval
In order to avoid rejection and accelerate your application:
- Gather necessary documents well in advance: income, ID, medical, and landlord consent.
- Ensure your property has an EPC rating of E, F, or G.
- Obtain a valid medical referral if applying on health grounds.
- Ensure that your current heating system matches the upgrade you are requesting.
- Correct all application errors before submission.
- Cooperate fully during the technical survey.
By following these steps, your chances of securing an upgrade such as a free boiler replacement, first-time central heating system, or insulation increase significantly.
The Bottom Line
The LA Flex pathway under the ECO4 scheme is one of the most valuable support routes to households that do not receive benefits but still experience cold and inefficient homes. Understanding the reasons behind application refusals helps you build a strong, successful case.
You will have significantly higher chances of getting approval and save long-term on energy bills, if you avoid common mistakes like missing documents, incorrect details, and misunderstanding eligibility.

FAQs
Most LA Flex rejections occur because of missing documents, income above the limit set by the council, no medical referral, incorrect details, or failure to meet the property rules under ECO4, such as EPC above D. Landlord refusal can be a reason for rejection.
Yes, LA Flex supports low-income or medically vulnerable households that are not on benefits. You must, however, meet the council’s criteria and provide the correct documentation. Otherwise, the application may be declined.
Not necessarily; you can still qualify through the medical route, but only with a valid referral. Income-based applications, without medical evidence, usually get rejected.
Submit correct documentation, check your EPC rating, acquire a medical referral, if necessary, gain permission from your landlord, and ensure your home is safe to install a new heating system. This will make you eligible for upgrades like free boilers or the First Time Central Heating Grant.
