Heat Pump Grant for Landlords: BUS Grant and Funding Options

If you are a landlord considering a heat pump for a rental property, the good news is clear: you are eligible for the Boiler Upgrade Scheme (BUS) grant of £7,500, the same amount available to owner-occupiers. Additional funding routes exist through ECO4 and social housing programmes, depending on your tenant's circumstances and the type of property you manage.

This guide covers everything landlords need to know about heat pump grants: who qualifies, how the process works, what the financial case looks like for rental properties, and why increasing numbers of landlords are making the switch.

The BUS Grant for Landlords

The Boiler Upgrade Scheme is the primary grant available to landlords. Here are the key points:

Grant Amount

  • Air source heat pump: £7,500
  • Ground source heat pump: £7,500

The amount is identical to what owner-occupiers receive. There is no reduced rate for landlords.

Eligibility for Landlords

To qualify as a landlord, you must meet the same standard eligibility criteria:

  • You own the property — you are the legal owner
  • The property is in England or Wales
  • Valid EPC with insulation recommendations addressed
  • Replacing an existing fossil fuel system (gas, oil, LPG, or electric storage heaters)
  • Not a new build
  • MCS-certified installer

No Property Value Cap

There is no upper limit on property value for the BUS grant. Whether your rental property is worth £80,000 or £800,000, you are eligible provided all other criteria are met.

Multiple Properties

The BUS grant is per property, not per person. If you own multiple rental properties, you can apply for the grant on each one separately. This makes it particularly attractive for portfolio landlords upgrading their entire stock.

How the Application Works for Landlords

The process is essentially the same as for owner-occupiers. Your MCS-certified installer handles the application through Ofgem:

  1. Get quotes from MCS-certified installers — use our free quote service
  2. Choose an installer and agree the work
  3. Installer submits the BUS application to Ofgem
  4. Ofgem approves the voucher (2-4 weeks)
  5. Installation takes place
  6. Grant is paid to the installer, deducted from your bill

Tenant Considerations

You will need to coordinate with your tenants regarding:

  • Access: The installer needs access to the property for the survey and installation
  • Disruption: Installation typically takes 1-3 days. Heating and hot water may be unavailable for periods during this time.
  • Communication: Inform tenants in advance about the work, timeline, and benefits
  • Void periods: Some landlords prefer to install during tenant changeovers to minimise disruption

ECO4 for Landlords

The ECO4 scheme offers another route, particularly if your tenant is on a low income. Under ECO4:

  • Eligibility is based on the tenant's circumstances, not yours
  • The tenant must receive qualifying means-tested benefits
  • The property must have an EPC rating of D, E, F, or G
  • The installation can be fully funded — at no cost to you or the tenant

Important Caveats for Landlords Under ECO4

  • Some ECO4 scheme managers may ask landlords to contribute a proportion of the cost
  • You may need to demonstrate that you are not already planning to improve the property
  • You cannot combine ECO4 with the BUS grant for the same installation

Which Is Better for Landlords: BUS or ECO4?

It depends on the situation:

  • BUS: You pay the balance after the £7,500 grant. You choose the installer and system. Faster. Your choice.
  • ECO4: Potentially free, but you do not choose the installer or system. May take longer. Depends on tenant eligibility.

Social Housing Landlords

If you are a social housing provider (housing association or council), separate funding is available through:

Social Housing Decarbonisation Fund (SHDF)

  • Government funding specifically for social housing energy efficiency improvements
  • Covers heat pump installations alongside insulation and other measures
  • Applied for by the housing provider, not individual tenants
  • Funding rounds are announced periodically by DESNZ

SHDF Key Points

  • Targets properties with EPC ratings below C
  • Aims to bring properties up to at least EPC C
  • Covers a significant proportion of the cost (typically 50% to 100%)
  • Requires a co-investment from the housing provider in many cases

If you manage social housing stock and are interested in heat pump installations, monitor SHDF funding round announcements and prepare applications in advance.

The Financial Case for Landlords

Upfront Costs After Grant

For a typical rental property receiving the BUS grant:

  • Installation cost: £10,000 to £13,000
  • BUS grant: -£7,500
  • Landlord pays: £2,500 to £5,500

EPC Improvement

Installing a heat pump typically improves a property's EPC rating by one to two bands. With minimum EPC requirements for rental properties tightening, this is increasingly important:

  • Current minimum for rental properties: EPC E
  • Proposed future minimum: EPC C (check latest legislation for confirmation dates)
  • A heat pump combined with insulation can move a property from E/F to C/B

Property Value and Appeal

  • Higher EPC ratings are associated with higher property values
  • Lower energy bills make properties more attractive to tenants
  • Heat pumps are a selling point for environmentally conscious tenants
  • Future-proofing against potential fossil fuel heating bans

Running Costs

Where tenants pay their own energy bills (which is most rental arrangements), a heat pump can reduce their heating costs. This makes the property more attractive and reduces the risk of rent arrears caused by high energy bills.

Practical Considerations for Landlords

Timing the Installation

  • Between tenancies: Ideal — no disruption, full access for installers
  • With tenants in situ: Possible but requires planning. Give adequate notice and arrange temporary heating if needed.
  • Seasonal timing: Spring and summer are best — tenants need heating less, and installers are more available

Choosing the Right System

For rental properties, consider:

  • Simplicity: Choose a system that is easy for tenants to use. Complicated controls lead to complaints and inefficient operation.
  • Reliability: Opt for established manufacturers with good warranty terms and UK service networks
  • Maintenance: Heat pumps require annual servicing. Factor this into your ongoing costs.
  • Hot water: Ensure the hot water cylinder is adequately sized for the number of tenants

Tenant Communication

Clear communication with tenants is essential:

  • Explain the benefits: lower energy bills, more comfortable home, better for the environment
  • Provide clear instructions on how to use the heat pump and controls
  • Explain that heat pumps work differently from gas boilers — they run at lower temperatures for longer periods
  • Provide an emergency contact for heating issues

Insurance and Legal

  • Inform your landlord insurance provider about the heat pump installation
  • Ensure the installation complies with Building Regulations
  • Keep all certificates (MCS, commissioning, warranty) for your records
  • Update the EPC after installation to reflect the improvement

HMO and Multi-Let Properties

Houses in Multiple Occupation (HMOs) and multi-let properties present additional considerations:

  • The BUS grant applies per property, not per unit within a property
  • The heat pump must serve the whole property
  • Hot water demand may be higher — ensure adequate cylinder sizing
  • Individual room heating controls are important for tenant satisfaction
  • Communal heating arrangements may require a different approach

Future Regulation: Why Landlords Should Act Now

Several regulatory trends make heat pump installation increasingly urgent for landlords:

  • Minimum EPC requirements: Future legislation may require rental properties to achieve EPC C, making energy efficiency improvements mandatory
  • Fossil fuel phase-out: Gas boiler installations in new properties are being phased out, and existing property regulations may follow
  • Grant availability: The BUS grant is available now but may not continue indefinitely. Acting while the £7,500 grant exists makes financial sense.
  • Tenant expectations: Tenants are increasingly aware of energy efficiency and may choose properties with lower running costs

Installing a heat pump now — while the BUS grant covers a substantial portion of the cost — is significantly cheaper than being forced to do it later without financial support.

Frequently Asked Questions

Can landlords get the BUS grant?

Yes. Private landlords are eligible for the full £7,500 BUS grant under the same terms as owner-occupiers. There is no reduced rate for landlords.

Is there a property value cap for landlord grants?

No. There is no upper limit on property value for the BUS grant. All properties that meet the eligibility criteria qualify, regardless of value.

Can I get the grant on multiple properties?

Yes. The grant is per property, not per person. You can apply for BUS on each rental property you own.

Do my tenants need to agree?

Legally, you should inform tenants about planned works and arrange access. Good practice is to explain the benefits and give reasonable notice. You may need to check your tenancy agreement regarding major works.

Can my tenant apply for the grant?

No. Only the property owner can apply for the BUS grant. If your tenant is on means-tested benefits, they may enable ECO4 eligibility — but the application still comes from the landlord's side.

Will installing a heat pump increase rent?

That is a commercial decision for you. Many landlords do not increase rent, seeing the investment as future-proofing and EPC improvement. Lower energy bills for tenants can justify a modest rent increase in some cases, but local market conditions should guide this.

What about holiday lets and Airbnb properties?

Holiday lets and short-term rental properties can qualify for the BUS grant provided they meet all other eligibility criteria. The property must have a valid EPC and be replacing an existing fossil fuel heating system.

Is there a deadline to apply?

The BUS scheme runs until March 2028. However, scheme budgets are allocated annually and could change. Applying sooner rather than later is advisable.
