A Complete Guide To Heat Pump Grants In Wales

What are heat pumps?

Heat pumps are innovative, energy-efficient systems that extract thermal energy from the environment-air, ground, or water-and convert it into heating for your home and hot water. Unlike conventional heating systems that generate heat by burning fuel, heat pumps transfer existing heat, making them far more sustainable. Air source heat pumps are the most common type, especially suited to the Welsh climate, while ground source heat pumps are an excellent option for properties with ample outdoor space.

Why are heat pumps gaining popularity in Wales?

In recent years, there has been a significant push across Wales to reduce carbon emissions and promote sustainable living. With heating accounting for a substantial portion of household emissions, replacing old systems with low-carbon alternatives like heat pumps has become a key priority. The Welsh Government’s commitment to achieving net-zero carbon emissions by 2050 has accelerated this movement, leading to an increase in public awareness, government support, and funding opportunities.

The importance of grants and financial support

While heat pumps are cost-effective in the long term-often reducing energy bills by 25–40%-the upfront cost can be daunting. Installation can range from £7,000 to £14,000 depending on the type and property requirements. Fortunately, government grants and schemes are in place to help homeowners cover these initial expenses, making sustainable heating a realistic goal for more people across Wales.

Overview of Heat Pump Grants in Wales

What are heat pump grants?

Heat pump grants are financial incentives designed to make it easier for homeowners to adopt low-carbon heating solutions. These grants can come in the form of lump-sum payments, installation subsidies, or full funding in specific cases. By lowering financial barriers, these grants support the UK’s broader climate goals while helping households save money.

Who provides these grants?

In Wales, heat pump grants are available through several channels:

  • The UK Government (e.g. via Ofgem or DESNZ)
  • The Welsh Government (e.g. the Nest scheme)
  • Local authorities and councils
  • Energy suppliers (e.g. British Gas, Octopus Energy)
  • Partner organisations and charities working on energy efficiency

Types of grants and financial incentives available

The most common grants include:

  • Boiler Upgrade Scheme (BUS): Replaces fossil fuel systems with low-carbon alternatives.
  • Nest (Welsh Government): Focuses on supporting low-income households.
  • ECO4 Scheme: Provided by energy suppliers, aimed at vulnerable households.
  • Local authority schemes: Often run limited-time programmes for specific regions or demographics.
  • Private and supplier-led promotions: Sometimes offer cashback, discounts, or financing options.

Government Support and National Schemes

The Boiler Upgrade Scheme (BUS)

What is the BUS?

The Boiler Upgrade Scheme is a UK-wide initiative managed by Ofgem and backed by the Department for Energy Security and Net Zero (DESNZ). It helps property owners in England and Wales switch from fossil fuel systems to greener alternatives like air and ground source heat pumps.

How much funding is available?

The scheme offers:

  • £7,500 towards the cost of an air source heat pump
  • £7,500 towards a ground source heat pump. This funding is paid directly to your installer, reducing the amount you pay upfront.

Eligibility criteria for homeowners in Wales

To be eligible, you must:

  1. Own the property (private homeowners or landlords)
  2. Replace an existing gas, oil, LPG, or electric heating system
  3. Have a valid EPC with no outstanding loft or cavity wall insulation recommendations
  4. Use an MCS-certified installer. New builds (except self-builds) are not eligible.

The Nest Scheme (Welsh Government)

Overview and aims

Nest is the Welsh Government’s flagship energy efficiency programme. It offers free energy-saving home improvements, including heat pumps, for eligible households. The scheme aims to reduce fuel poverty and lower energy bills.

Who qualifies?

You may be eligible if:

  • You own or privately rent your home
  • Your home is energy inefficient
  • You or someone in your household receives a means-tested benefit (e.g. Universal Credit, Pension Credit)
  • Your annual household income is below a certain threshold

How to apply

You can apply by:

  • Calling the Nest helpline (0808 808 2244)
  • Visiting the Nest website to fill out a short application
  • Booking a home energy assessment to determine eligibility and appropriate upgrades

Local Authority and Council-Specific Schemes

Examples of local incentives

Some councils in Wales run local energy efficiency schemes or participate in UK-wide projects. For example:

  • Cardiff Council has partnered on renewable pilot programmes.
  • Carmarthenshire and Gwynedd have run community energy projects offering additional grants.

How to check what’s available in your area

Visit your council’s website or contact their energy efficiency officer. Schemes may change based on funding cycles and local priorities.

Private and Energy Supplier Heat Pump Grants In Wales

ECO4 Scheme (Energy Company Obligation)

How it works

ECO4 is a government-mandated scheme requiring large energy suppliers to improve the energy efficiency of homes. It focuses on supporting low-income and vulnerable households through fully or partially funded improvements, including the installation of heat pumps.

Eligibility in Wales

Eligibility is based on:

  • Receiving qualifying benefits (e.g. Income Support, Housing Benefit)
  • Living in social housing or private homes with low EPC ratings (E, F, or G)
  • Being referred through the LA Flex route (local authority flexible eligibility)

Energy supplier contributions and offers

British Gas, Octopus Energy, etc.

Some suppliers run their own heat pump programmes, offering subsidies, free surveys, or flexible finance plans. Octopus Energy, for example, has gained attention for offering discounted heat pump installations to eligible customers.

Compatibility with other schemes

While it’s possible to combine some incentives, many grant schemes prohibit double funding. It’s essential to confirm compatibility before applying. Green Homes Group can help you navigate this.

Who Can Apply for a Heat Pump Grant in Wales?

Homeowners vs tenants

Most grant schemes target homeowners and private landlords. Tenants are generally ineligible unless their landlord agrees to apply on their behalf.

Income and benefit-based eligibility

Schemes like Nest and ECO4 focus on households receiving income-related benefits or with limited financial means. You may need to provide documentation, such as benefit letters or bank statements.

Property type and EPC considerations

A property’s suitability is assessed by looking at:

  • Insulation levels (walls, loft, floor)
  • Existing heating system
  • EPC rating (D or lower is often preferred for funding). If upgrades are required, schemes may offer support for those improvements before installing a heat pump.

Common Questions About Heat Pump Grants in Wales (FAQ)

Can I get a heat pump grant if I live in a rural area?

Yes. In fact, homes in off-grid rural areas are often prioritised for grants like BUS and Nest because they typically rely on more expensive fuels like oil or LPG.

Are air source and ground source heat pumps both covered?

Yes. Most schemes cover both, but the level of funding may differ. Ground source heat pumps tend to be more expensive and may require additional eligibility checks.

How long do applications take to process?

It varies:

  • BUS: Usually 2–4 weeks
  • Nest: Typically within 4–6 weeks from assessment
  • ECO4: May take up to 2–3 months due to referrals and approvals

Can I combine different grants?

You usually cannot combine major schemes like BUS and ECO4. However, some smaller local grants or supplier offers may be used in conjunction with national funding. Always confirm before proceeding.

What if I’ve already installed a heat pump?

Most schemes require pre-approval. Retroactive claims are rarely allowed, so it’s best to apply before starting any work. If you’ve already installed one, check with an advisor to explore any post-installation incentives.

Benefits of Installing a Heat Pump in Wales

  • Lower energy bills: Switching to a heat pump can significantly cut heating costs, especially if you’re currently using oil, LPG, or electric systems.
  • Reduced carbon emissions: Heat pumps emit significantly less CO2 than gas or oil boilers. Switching helps Wales move closer to its carbon reduction targets.
  • Increased home value: Energy-efficient homes are increasingly in demand. Installing a heat pump, along with improving insulation, can boost your home’s resale value.
  • Long-term savings with grants: By reducing upfront costs, grants shorten the payback period, making the investment more attractive and financially viable.

Potential Barriers and How to Overcome Them

Upfront costs (even with grants)

Even with a grant, some cost remains. To manage this:

  • Consider finance options
  • Apply for insulation grants first
  • Work with advisors to reduce costs wherever possible

Property suitability

Some properties, especially older homes, may need insulation or radiator upgrades. A survey can identify cost-effective fixes to make your home heat pump-ready.

Misinformation and confusion around eligibility

Rules can be complex and differ by scheme. Green Homes Group offers clear, no-jargon advice to help you navigate the process.
