What Is the Government Heat Pump Scheme?

Are you tired of sky-high heating bills? Wondering how you can make your home more eco-friendly without breaking the bank? The UK government has your back with some fantastic schemes to help you switch from old-fashioned heating to modern heat pumps.
These programs are game-changers. They're helping families across the UK cut their energy costs while doing their bit for the planet. But what exactly are these schemes, and could you benefit from them?
What Are Government Heat Pump Schemes?
Think of government heat pump schemes as your financial helping hand. They're designed to make green heating affordable for everyone. Why should you care? Because they can save you thousands of pounds while making your home warmer and more comfortable.
The main goal is simple. Replace your old gas or oil boiler with a clean, efficient heat pump. This cuts your carbon footprint, lowers your bills, and helps the UK reach its net-zero target by 2050.
Right now, there are two big schemes doing the heavy lifting. The Boiler Upgrade Scheme (BUS) and the Energy Company Obligation 4 (ECO4) scheme. Plus, Scotland, Wales, and Northern Ireland have their own programs too.
The Boiler Upgrade Scheme (BUS)
Ever heard of the BUS scheme? It's the government's flagship program for heat pumps in England and Wales. Launched on April 1, 2022, it's got a massive £450 million budget running until March 2028.
Here's the exciting part. The government is putting even more money behind this. They've nearly doubled the budget to £295 million for 2025-26. That shows they're serious about helping you make the switch.
Grant Amounts and Coverage
Ready for some good news? Here's what you can get under the BUS scheme:
-
£7,500 for air source heat pumps
-
£7,500 for ground source heat pumps (including water source and shared ground loops)
-
£5,000 for biomass boilers
Notice how heat pump grants jumped to £7,500 in October 2023? That's a significant boost from before. Your certified installer applies this grant directly. This means your final bill is much lower from day one.
Eligibility Requirements
Wondering if you qualify? Let's break it down:
Your Property Must:
-
Be in England or Wales
-
Be it your home or a small business building
-
Have a valid Energy Performance Certificate (EPC)
-
Need a system under 45kWh capacity
Your Heating System Must:
-
Replace an old fossil fuel boiler (gas, oil, or LPG)
-
Replace electric storage or panel heaters
-
Meet minimum efficiency standards
-
Do not replace an existing low-carbon system
You Must:
-
Own the property
-
Not having received previous government heat pump funding
-
Live in an existing home (not new-build or social housing)
Got a biomass boiler in mind? There's a catch. You need to be in a rural area without gas connection. Heat pumps don't have this restriction, though.
Application Process
Here's where it gets easy. You don't apply directly. Your MCS-certified installer handles everything. How does it work?
First, they assess your property and give you quotes. Then they check that you meet all requirements. Next, they submit the voucher application for you. You've got 120 days to get the system installed. Finally, they deduct the grant from your final bill.
Simple, right?
The ECO4 Scheme
What if you're on a tight budget? The ECO4 scheme might be perfect for you. It focuses on helping low-income families and those struggling with fuel poverty across Great Britain.
This scheme runs until March 2026. Energy companies fund it, and they distribute money to eligible households. Here's the exciting bit - there's no set funding limit. You could get your entire heat pump installation covered.
Funding and Coverage
How does ECO4 compare to BUS? It's much more generous if you qualify:
-
Unlimited funding per household
-
Can cover 100% of installation costs
-
Often includes extra energy efficiency measures.
-
May add insulation, solar panels, and more
Imagine getting a complete home energy makeover for free. That's what ECO4 can offer eligible families.
Eligibility Criteria
ECO4 is more selective than BUS. You need to receive certain benefits:
Qualifying Benefits Include:
-
Income-based Jobseeker's Allowance
-
Income-Related Employment & Support Allowance
-
Income Support
-
Pension Credit Guarantee
-
Working Tax Credit
-
Child Tax Credits
-
Universal Credit
-
Housing Benefit
-
Warm Home Discount Scheme Rebate
Your Property Must:
-
Have EPC ratings of D, E, F, or G
-
Be anywhere in Great Britain (except Northern Ireland)
-
Work for homeowners and private tenants

Heat Pump Technology Types
Air Source Heat Pumps
What exactly is an air source heat pump? Think of it as a reverse refrigerator. It pulls heat from outside air and pumps it into your home. Even when it's cold outside, these clever devices keep working.
They're the most popular choice in the UK. Why? Lower costs and minimal space needs. You'll see an outside unit (like air conditioning) plus indoor components including a hot water cylinder.
Efficiency? They're 300-400% efficient. That means for every unit of electricity used, you get 3-4 units of heat. Compare that to your old boiler!
Ground Source Heat Pumps
Want even better efficiency? Ground source heat pumps might be for you. They use underground pipes to extract heat from the earth. The ground temperature stays steady year-round.
You'll get higher efficiency, typically 350-520% efficient all year. But there's a catch. You need significant outdoor space and higher installation costs.
The pipes go either horizontally (1-2 meters deep) or vertically (60-100+ meters deep). Got a big garden? This could be perfect.
Installation Process and Requirements
MCS Certification Requirement
Want government grants? Your installer must be MCS certified. This ensures they meet strict standards and can handle grant paperwork properly.
MCS certification means:
-
Following strict installation standards
-
Having skilled, trained staff
-
Completing approved training courses
-
Meeting ongoing competency requirements
Typical Installation Timeline
Curious about the installation process? Here's what happens:
-
Property Assessment: Your installer evaluates your home and sizes the system correctly.
-
Quote and Grant Application: You get quotes, and they apply for grants.
-
Preparation: Out with the old boiler, in with new pipework.
-
Installation: The External unit goes in, internal components get connected.
-
Connection: All the plumbing, electrical, and controls get linked up.
-
Testing: Everything gets checked, and you get trained on using it.
Air source heat pumps typically take 2-3 days. Ground source can take 2-5 weeks due to groundwork.
Cost Considerations and Financial Impact
Installation Costs
What will this actually cost you? Here are typical ranges:
Air Source Heat Pumps:
-
Total cost: £4,000-£15,000
-
After £7,500 BUS grant: Usually £6,500-£7,500 net cost
-
Much shorter payback period with grant support
Ground Source Heat Pumps:
-
Total cost: £11,500-£27,500
-
After £7,500 BUS grant: Still a substantial investment
-
Higher efficiency provides better long-term returns
Ongoing Maintenance Costs
What about running costs? Heat pumps are pretty low-maintenance:
Annual Servicing:
-
Air source: £150-£300 (average £200)
-
Ground source: £200-£350 (average £250)
-
Repairs: £150-£2,000 depending on what needs fixing
Operational Benefits
Why make the switch? The benefits are compelling:
-
Much Higher Efficiency: 300-400% vs gas boilers
-
Lower Running Costs: Especially vs LPG, oil, and electric heating
-
Reduced Carbon Emissions: Big environmental benefits
-
Longer Lifespan: Lasts 5-10 years longer than traditional boilers
Future Outlook and Government Commitments
Where is all this heading? The government wants to install 600,000 heat pumps annually. They're backing this with continued investment, simpler planning rules, and better awareness campaigns.
The combination of BUS, ECO4, and regional programs covers everyone. Whether you're wealthy or struggling, there's support available — especially when concerns around air source heat pump costs are holding people back.
The success speaks for itself. Record installations in 2024 show growing acceptance. As technology improves and costs drop, these schemes will keep driving the clean heating revolution.
