Are you a private tenant in the UK struggling with rising energy bills and an inefficient boiler? You might be eligible for a free boiler replacement through the UK Government’s ECO4 Scheme one of the most beneficial initiatives for low-income households and renters.
This guide will explain how private tenants can apply for a free boiler under the ECO4 scheme, what the eligibility criteria are, and how to start your application through Apply Energy Grants or your local council.
What Is the ECO4 Scheme?
The Energy Company Obligation (ECO) is a UK government-funded program that requires large energy companies to help households become more energy efficient.
The ECO4 phase (running from 2022 to 2026) is the latest stage of this initiative. It provides free or heavily subsidised upgrades such as:
- New A-rated energy-efficient boilers
- Central heating systems
- Insulation (cavity wall, loft, and floor)
- Heating controls and thermostats
- Renewable heating options (like air source heat pumps)
The ECO4 scheme is part of the UK’s commitment to reducing carbon emissions and tackling fuel poverty — ensuring homes stay warm while reducing energy waste.
Can Private Tenants Apply for a Free Boiler?
Yes — private tenants can qualify for ECO4, but there are a few important conditions.
Because you don’t own the property, your landlord’s permission is required for any installation or heating upgrade. Once you get that consent, you can apply through an approved ECO4 installer or through Apply Energy Grants to check your eligibility.
Many local councils across England, Scotland, and Wales are actively encouraging private renters to take advantage of these free energy-saving upgrades.
Eligibility Criteria for the ECO4 Free Boiler Grant
To qualify for a free boiler under the ECO4 scheme, private tenants must meet certain conditions.
1. Property Energy Rating (EPC)
Your property’s Energy Performance Certificate (EPC) rating must be D, E, F, or G — meaning it’s not energy efficient.
If you’re unsure about your home’s EPC rating, you can check it online at gov.uk/find-energy-certificate.
2. Benefit Eligibility
At least one member of your household should be receiving a qualifying government benefit, such as:
- Universal Credit
- Income Support
- Pension Credit
- Housing Benefit
- Child Tax Credit
- Working Tax Credit
- Income-based Jobseeker’s Allowance
- Income-related Employment & Support Allowance
If you don’t receive benefits, you may still qualify under the “ECO4 Flex” route where your local council assesses your income level and home energy needs.
3. Income Level
Households earning below £36,000 per year (combined income) are often eligible, even without benefits, under Local Authority Flexible Eligibility (LA Flex).
4. Landlord Consent
Written consent from the landlord is required, as the boiler and heating system are part of the property’s structure.
How to Apply for the ECO4 Free Boiler Scheme?
Applying for a free boiler grant is easier than you might think. Follow these simple steps:
Step 1: Check Your Eligibility
Visit Apply Energy Grants or another approved ECO4 provider’s website. You’ll usually complete a quick eligibility checker form by entering:
- Your postcode
- Type of property
- Benefits received (if any)
- Current boiler type and condition
Step 2: Contact Your Landlord
Let your landlord know about the scheme and get written permission for the installation. Many landlords agree because the grant increases the property’s value and EPC rating — at no cost to them.
Step 3: Property Survey
If you qualify, a certified installer will visit your home to carry out a free energy assessment. This includes checking the boiler’s efficiency, insulation levels, and the feasibility of installation.
Step 4: Installation
Once approved, a TrustMark-registered installer will fit the new boiler — often within 1–2 weeks. The process is quick and minimally disruptive, and your old boiler will be safely removed.
Step 5: Post-Installation Check
A quality inspection ensures that your new system meets all ECO4 standards. You’ll also get updated EPC documents showing your improved energy efficiency.
Local Authority and Council-Backed Schemes
Many councils across the UK partner with the ECO4 program and offer their own local grants. These include:
- Warm Homes: Local Grant (available across England)
- LA Flex ECO4 Schemes (administered by councils such as Birmingham City Council, Leeds City Council, and Bristol City Council)
- Home Upgrade Grant (HUG2) — for off-gas homes
To find local options, visit your council’s website and search for “energy efficiency grants” or “ECO4 funding.”
For example:
- Camden Council offers free insulation and heating grants for low-income tenants.
- Manchester City Council runs “Warm Homes Manchester,” which supports both homeowners and private renters.
How Much Is Covered? Is It Really “Free”?
If you meet the full eligibility criteria, your new boiler will be 100% free, with no upfront cost.
In some cases, a small contribution might be required if the property needs additional work — like pipework or insulation — but most applicants pay nothing at all.
The grant typically covers:
- Boiler unit and parts
- Full installation
- Old boiler removal
- Safety checks and certification
This makes it one of the most cost-effective ways for tenants to enjoy modern, efficient heating.
Benefits of Getting a Free Boiler
- Lower Energy Bills — New A-rated boilers can cut heating bills by up to 30%.
- Warmer, Healthier Homes — More consistent heating and less dampness.
- Reduced Carbon Footprint — Environmentally friendly and compliant with net-zero goals.
- Increased Property Value — Your landlord benefits too — higher EPC rating = higher rental value.
- No Upfront Cost — Government-backed funding covers most or all expenses.
Example: How It Works Locally
If you live in Birmingham, the city council works with ECO4-approved contractors under the Warm Homes Birmingham initiative.
Similarly, Leeds City Council and Manchester City Council have ECO4 Flexible Eligibility programs for private renters.
All you need is your postcode, income proof, and landlord’s consent, and the rest is managed by the installer and grant provider.
Final Thoughts
The ECO4 scheme is a fantastic opportunity for private tenants across the UK to improve their heating systems at little to no cost. With government-funded support, tenants can enjoy warmer homes, lower bills, and better living conditions all while helping the UK reach its Net Zero 2050 targets.
So if you’re renting a property with an old or broken boiler, don’t wait — check your eligibility today with Apply Energy Grants and take the first step towards a warmer, more energy-efficient home.
