£9,000 Heat Pump Grant in Wales: A Guide for Pembrokeshire Homeowners
If your Pembrokeshire home is off the gas grid and you are replacing an oil or LPG heating system, you could receive up to £9,000 towards an eligible air-to-water or ground-source heat pump through the Boiler Upgrade Scheme.
Last updated: 22 August 2026. Scheme rules can change, and final eligibility is confirmed through the official application process.
What is the £9,000 heat pump grant?
The Boiler Upgrade Scheme, often shortened to BUS, helps property owners in England and Wales replace fossil-fuel heating with an eligible low-carbon heating system. The scheme is installer-led: an MCS-certified installer submits the application, manages most of the paperwork and claims the grant after the installation is complete.
The higher £9,000 amount is intended for eligible off-gas-grid properties replacing oil or LPG. That makes it particularly relevant across rural Pembrokeshire, including Tenby, Saundersfoot, Pembroke, Haverfordwest and the wider county.
Important: the grant is a fixed contribution towards an eligible installation. It may not cover the full cost of the heat pump, system design or any property-specific upgrades.
How much is the heat pump grant in Wales?
The amount depends on the property, the heating system being replaced and the type of eligible heat pump being installed.
| Eligible installation | Potential grant |
|---|---|
| Air-to-water or ground-source heat pump at an eligible off-gas-grid property replacing oil or LPG | £9,000 |
| Other eligible air-to-water or ground-source heat pump installations | £7,500 |
The £9,000 level became available on 21 July 2026 and is currently due to remain available until 31 March 2027. You can check the latest amounts on the GOV.UK Boiler Upgrade Scheme guidance and read the detailed process on the Ofgem website.
Who could qualify for the £9,000 grant?
The higher grant may be available when the property and proposed system meet the Boiler Upgrade Scheme rules. The main points include:
- The property is in England or Wales.
- The property does not have a mains gas connection.
- The existing heating system uses oil or LPG.
- The new system is an eligible air-to-water or ground-source heat pump.
- The installation and products meet the remaining scheme requirements.
- The work is completed by an MCS-certified installer.
Eligible homeowners and private landlords can use the scheme. Most new-build properties and social housing are excluded, although qualifying self-builds can be treated differently. Your installer and Ofgem will confirm final eligibility before the grant is approved.
What does off the gas grid mean?
For the higher grant, the property must not have a mains gas connection. This is checked as part of the application. If your property does not meet the higher-grant rules, it may still qualify for the standard £7,500 contribution towards an eligible air-to-water or ground-source system.
How does the application process work?
- Initial enquiry: tell us about your property, current heating system and what you would like to achieve.
- Home survey: we assess the property, its heat loss, existing heating system and possible locations for the equipment.
- System design and quotation: you receive a proposal based on the property rather than a one-size-fits-all estimate.
- Grant application: the MCS installer applies on your behalf. Ofgem then contacts you to confirm your consent and eligibility.
- Installation and handover: after approval, the system is installed, commissioned and explained to you. The installer claims the approved grant from Ofgem.
The value of an approved grant should appear as an upfront reduction on the installer’s quotation, so you can see what the grant contributes and what remains payable.
Will my home need new radiators or insulation?
Radiators
Not every radiator automatically needs replacing. A room-by-room heat-loss calculation shows the output each room needs. Some existing radiators may be suitable, while others may need to be larger.
Insulation
Heat pumps work best when unnecessary heat loss is reduced. The right advice depends on the construction, ventilation, damp risk and existing insulation, particularly in older stone or renovated rural homes.
These details are why a proper survey and system design matter. The aim is to create a system that can heat the home comfortably at suitable flow temperatures, not simply replace the boiler on a like-for-like basis.
Can an older Pembrokeshire home have a heat pump?
An older home is not automatically unsuitable. What matters is the measured heat loss, the space available for the equipment, the condition of the existing heating system and whether the radiators and controls can deliver comfortable heating efficiently.
Pembrokeshire has a wide mix of stone cottages, bungalows, farmhouses and newer properties. Each needs its own assessment. A survey can identify practical upgrades and help you understand the likely installation cost before you make a decision.
Heat pump grant questions
Can a home with mains gas receive the £9,000 grant?
No. The higher amount requires the property to be off the mains gas grid and replacing oil or LPG. A property that does not meet those conditions may still qualify for £7,500 towards an eligible air-to-water heat pump, subject to the remaining rules.
Can private landlords use the Boiler Upgrade Scheme?
Yes, private landlords can use the scheme when the property, existing heating and proposed installation meet the eligibility rules.
Is the grant paid directly to the homeowner?
No. The installer applies for and claims the approved grant. Its value should be shown as an upfront discount on your quotation.
Will the grant cover the whole installation?
Not necessarily. It is a fixed contribution. Your quotation may also include system design, radiators, a hot-water cylinder, electrical work or other property-specific changes.
How long is the higher grant expected to be available?
Current official guidance says the additional £1,500 for eligible off-gas-grid oil or LPG replacements is available until March 2027. Always check the latest scheme guidance before relying on an amount.
