Boiler Grants for Private Tenants: Who Applies and Who Gives Permission?
Information checked and updated: 30 July 2026.
Private tenants can qualify for heating and energy-efficiency support, but the application is rarely handled by the tenant alone. The tenant’s income, benefits, health circumstances and the property’s Energy Performance Certificate (EPC) usually determine eligibility. The landlord owns the heating system and must give written permission before an installer alters the property.
“Boiler grant” is now a broad search term. Some programmes fund boiler repair or replacement in limited circumstances; others prioritise insulation, first-time central heating, heat pumps or whole-house upgrades. In England, ECO4 generally does not fund an ordinary boiler repair or replacement in a privately rented home, while the Warm Homes: Local Grant cannot fund a new gas boiler.
This guide explains who makes the enquiry, who signs the consent forms, what evidence is needed and what to do if the boiler is already broken.
Check your ECO4 eligibility
Answer a few quick questions to see whether your household may qualify for ECO4 support.
Quick answer
A private tenant normally makes the initial enquiry because eligibility is based mainly on the household living in the property. The council, energy supplier or scheme administrator checks the tenant’s income, benefits, vulnerability and the home’s EPC. The landlord must usually confirm ownership, give written consent and approve access because the boiler and building belong to them.
Under some schemes, the landlord is treated as the grant beneficiary and may need to sign declarations or contribute. Never authorise heating-system or structural changes without the owner’s approval. If the boiler is broken, report it to the landlord first: repairing heating and hot water is generally the landlord’s responsibility, not a cost the tenant should have to cover through a grant.
Current boiler-grant routes for private tenants
| Scheme or route | Area | Who starts the process? | What may be funded? | Permission and cost position |
|---|---|---|---|---|
| ECO4 | England, Wales and Scotland | Tenant, council, supplier or delivery partner | Whole-house upgrades; ordinary boiler repair or replacement is generally excluded in private rented homes | Landlord consent required; support is not guaranteed and a contribution may be requested |
| Warm Homes: Local Grant | England | Tenant or local authority | Insulation, solar and low-carbon heating for eligible EPC D–G homes; not new gas boilers | Landlord declaration required; one property may be fully funded per landlord, with a 50% contribution for later properties |
| Nest | Wales | Tenant contacts Nest | Efficiency measures; boiler or storage-heater repair or replacement may be considered where there is no heating or hot water | Nest requests permission from the landlord |
| Warmer Homes Scotland | Scotland | Tenant contacts Home Energy Scotland | Assessed heating and efficiency measures, with restrictions for rented homes | Warmworks obtains permission; the landlord may fund work that is already their legal duty |
| Boiler Upgrade Scheme | England and Wales | Property owner instructs an MCS installer | Heat pumps or eligible biomass, not a new gas boiler | The landlord is the applicant; the installer submits the claim |
| Northern Ireland support | Northern Ireland | Enquiry depends on the local route | The Boiler Replacement Scheme is closed; check current Affordable Warmth support locally | Owner involvement is required before work starts |
ECO4 runs until 31 December 2026. For private renters, GOV.UK says the property normally needs an EPC rating of E, F or G and the owner’s permission. Ofgem stresses that ECO is an energy-company obligation, not a guaranteed grant: suppliers choose the projects they fund and the level of support offered.
England’s Warm Homes: Local Grant is delivered by participating local authorities for low-income households in privately owned EPC D–G homes. Household income is usually £36,000 or less, although qualifying benefits or eligible postcodes provide alternative routes. A landlord declaration is required, tenants should not contribute to improvement costs, and new gas boilers cannot be funded.
In Wales, eligible private tenants can approach Nest and provide their landlord’s details so consent can be requested. Boiler repair or replacement may be considered where the home has no heating or hot water.
In Scotland, Warmworks must obtain landlord permission, and measures the landlord is already legally required to provide may be excluded.
Who does what?
| Stage | Tenant | Landlord or property owner | Scheme provider or installer |
|---|---|---|---|
| Initial check | Supplies household and tenancy information | Confirms willingness to participate | Screens the household and property |
| Evidence | Provides income, benefit and occupancy documents | Provides ownership and property details | Confirms the eligibility route |
| Survey | Gives access and describes heating problems | Approves access | Assesses heat loss and suitable measures |
| Consent | Reviews the proposal | Signs consent, declarations and any contribution agreement | Records permission before work starts |
| Installation | Cooperates with access | Approves the final scope | Installs, commissions and supplies warranties |
| Aftercare | Reports faults | Maintains landlord-owned equipment | Handles defects covered by guarantees |
Who should apply first?
The tenant should usually make the first enquiry for means-tested or fuel-poverty support. This avoids a landlord submitting an application where the occupants do not meet the household criteria.
The tenant may need to provide:
- Proof of identity and address
- A tenancy agreement or evidence of occupancy
- Household income information
- Evidence of qualifying benefits
- Details of relevant health conditions
- Recent energy bills
- Information about the existing heating system
After a positive initial check, the landlord may need to:
- Prove ownership and confirm the tenancy
- Provide the EPC or permit an assessment
- Consent to surveys, installation and data processing
- Approve changes to heating, radiators, controls or insulation
- Accept warranty and maintenance obligations
- Agree any required contribution
Under the Warm Homes: Local Grant, the landlord declaration also confirms that rent should not be increased directly because of government-funded upgrades.
How to apply in six steps
1. Report a broken boiler
Notify the landlord or managing agent in writing and keep copies of messages, dates, photographs and engineer reports. A grant application should not replace an urgent repair request.
2. Check the EPC
ECO4 private-rented eligibility usually focuses on EPC E–G, while Warm Homes: Local Grant in England covers EPC D–G homes. An EPC assessment may be arranged if the existing certificate is missing or outdated.
3. Contact the correct service
Try the local authority in England, Nest in Wales, Home Energy Scotland in Scotland, or the relevant Northern Ireland council or Housing Executive service. ECO enquiries can also be made through an obligated energy supplier.
4. Request provisional eligibility
Ask what measures are likely to be recommended, how much funding may be available and whether the landlord must contribute.
Provisional eligibility is not final approval. The property normally needs to be surveyed before funding and installation can be confirmed.
5. Obtain written landlord consent
The consent should identify:
- The property
- The proposed measures
- Access arrangements
- Any landlord contribution
- Responsibility for additional work
- Guarantees and maintenance obligations
Verbal permission is not sufficient protection for the tenant, landlord or installer.
6. Wait for formal approval
Confirm the approved installer, scope of work, contribution, guarantees and complaints process before work starts.
Be cautious when an installer claims that funding is guaranteed before completing household checks and a property assessment.
Will the tenant or landlord have to pay?
A grant-funded project may be fully funded, partly funded or declined after survey. ECO providers can offer different funding levels and may ask for a contribution.
Under England’s Warm Homes: Local Grant, tenants are not expected to contribute. One eligible property per landlord can be fully funded, while subsequent properties owned by that landlord require a 50% landlord contribution.
The Boiler Upgrade Scheme is owner-led rather than a private-tenant grant. An MCS-certified installer applies on the landlord’s behalf.
Current support includes:
- £7,500 for an air-to-water heat pump
- £7,500 for a ground-source heat pump
- £2,500 for an air-to-air heat pump
- £5,000 for an eligible biomass boiler
- £9,000 for qualifying off-gas-grid oil or LPG replacements until 31 March 2027
The landlord must pay any remaining cost.
An accurate quotation always requires a survey. Additional costs may arise where the property needs insulation, radiator changes, electrical upgrades, asbestos management, flue alterations or other building work.
What if the landlord refuses permission?
A scheme cannot normally install a boiler, heat pump or insulation without the property owner’s consent.
Give the landlord a written summary covering:
- The proposed grant
- The recommended improvements
- Installer accreditations
- Product and installation warranties
- Expected disruption
- Any required contribution
- Likely improvements to the property
The equipment and improvements usually remain with the property, rather than belonging personally to the tenant.
Where the boiler is broken, treat the refusal as a repairs issue as well as a funding issue. In England, landlords are responsible for heating and hot-water repairs, and tenants cannot be forced to undertake repairs that are the landlord’s responsibility. Scotland also limits grant measures where the work falls under the landlord’s existing repairing duty.
Do not withhold rent or commission major work without professional advice. Contact the council’s private-sector housing team, Citizens Advice or the relevant national tenancy service if the landlord fails to act.
Broken boiler or planned energy upgrade?
There is an important difference between repairing a failed boiler and improving the property’s energy efficiency.
A landlord’s existing repair responsibilities do not disappear because a grant might be available. If the boiler stops providing heating or hot water, the tenant should notify the landlord immediately.
A planned energy upgrade is different. It may involve replacing fossil-fuel heating with a heat pump, adding insulation, changing radiators or installing better controls. These measures normally require a survey, funding approval and specific owner consent.
Tenants should not be pressured into signing a grant agreement that transfers the landlord’s normal repair costs to them.
Why the installer matters
Eligibility does not guarantee a good outcome. Poor assessment can lead to high bills, cold rooms, excessive noise, unsuitable controls and warranty disputes.
Check for:
- Gas Safe registration for gas work
- MCS certification for eligible low-carbon systems
- TrustMark registration where required
- Appropriate product guarantees
- A written complaints process
- Clear aftercare arrangements
Ask for heat-loss calculations, system sizing, proposed controls, radiator changes, warranties and maintenance requirements. The tenant should receive operating instructions, while the landlord should retain commissioning certificates and guarantee documents.

Check my tenant eligibilityConclusion:
For most private-tenant boiler grants, the tenant begins the eligibility enquiry and the landlord gives legal permission. The tenant’s circumstances open the door; the owner’s consent allows the work to proceed.
Do not assume that a “free boiler” advertisement applies to your tenancy. ECO4 restricts replacement heating in private rented homes, Warm Homes: Local Grant does not fund new gas boilers, and the Boiler Upgrade Scheme is intended for owner-led low-carbon heating.
Start with the property location, EPC rating, household eligibility and condition of the existing heating system. Obtain a written funding offer and written landlord consent before installation.
