Boiler Upgrade Scheme 2026 is making waves as one of the UK’s most accessible routes to affordable, low-carbon heating. If you’re eyeing a switch from your old gas or oil boiler to a modern heat pump, this government-backed program could slash thousands off your installation costs right now.
Launched back in 2022 and continually strengthened, the scheme sits at the heart of the broader Warm Homes Plan heat pump grant eligibility 2026 framework. It delivers straightforward upfront grants—primarily £7,500 for most heat pumps—helping everyday homeowners and landlords go greener without breaking the bank. With recent extensions and tweaks announced in late 2025 and rolled out into 2026, the timing feels perfect for action.
Why the buzz? Energy bills remain stubborn, fossil fuel prices fluctuate, and the push toward net-zero homes is accelerating. The Boiler Upgrade Scheme 2026 offers a practical, no-fuss way to cut your heating emissions and future-proof your property.
What Exactly Is the Boiler Upgrade Scheme in 2026?
Think of the Boiler Upgrade Scheme (often called BUS) as the government’s direct incentive to replace polluting heating systems with cleaner alternatives. Administered by Ofgem, it provides capital grants deducted straight from your installer’s quote—no complicated claims later.
In 2026, the core offer remains rock-solid:
- £7,500 for air-source heat pumps (ASHPs)
- £7,500 for ground-source or water-source heat pumps (GSHPs/WSHPs)
- £5,000 for biomass boilers (less common but still supported)
Recent expansions (phased in from late 2025 into 2026) now include air-to-air heat pumps—great if you want cooling in summer too—and even heat batteries in some cases. This makes the scheme more versatile than ever.
The budget? A hefty £295 million allocated for the 2025/26 financial year, with extensions confirmed through to 2028/29 (and potentially 2029/30 under the Warm Homes Plan). That’s serious commitment—enough to support tens of thousands of installations annually.
This ties directly into warm homes plan heat pump grant eligibility 2026, where the BUS acts as the universal entry point for heat pump support, complemented by targeted help for low-income households.
Key Updates and Changes for Boiler Upgrade Scheme 2026
The government didn’t just extend the scheme—they refined it based on real-world feedback.
Major 2026 highlights include:
- Inclusion of air-to-air heat pumps (with grants around £2,500 in some configurations, though air-to-water remains the £7,500 standard)
- Greater flexibility for hybrid systems (heat pump + existing boiler backups)
- Relaxed rules around Energy Performance Certificates (EPCs) in certain cases, making it easier for older properties
- Support for exhaust air heat pumps and heat batteries starting to roll out
These tweaks address common barriers: not every home suits a pure air-source setup, and hybrids offer a gentler transition for some. Plus, with no outright ban on new gas boilers announced in the Warm Homes Plan, the focus stays on positive incentives rather than mandates.
It’s like upgrading from a clunky old car to a hybrid—smoother, cleaner, and subsidized so the jump feels manageable.
Who Qualifies for the Boiler Upgrade Scheme 2026?
Eligibility keeps things simple and broad—no means-testing here, unlike some targeted grants.
You generally qualify if:
- You own the property (homeowners, private landlords, or even second homes/business properties in England or Wales)
- You’re replacing a fossil fuel heating system (gas, oil, LPG, coal, or non-heat-pump electric heating)
- Your property has a valid EPC (issued within the last 10 years, though some flexibility applies in 2026)
- The installation uses an MCS-certified installer (they handle the voucher application)
Exclusions? New-build homes usually don’t qualify (except rare self-builds), and social housing has separate funding routes. Properties already with a low-carbon heating system typically miss out too.
The beauty? It’s open to most people with an outdated boiler. Off-grid homes often see the biggest bill drops, but even urban gas-connected properties benefit massively.
This universal access makes Boiler Upgrade Scheme 2026 a cornerstone of warm homes plan heat pump grant eligibility 2026—it’s the first stop for many before exploring additional low-income pots.
How to Apply: Step-by-Step in 2026
Applying feels refreshingly straightforward—no mountains of forms on your end.
- Find an MCS-certified installer (search via the MCS website or trusted directories)
- Get quotes and discuss your home’s needs (surveys check suitability, insulation levels, etc.)
- The installer applies for the voucher through Ofgem
- You pay the reduced amount after installation (grant deducted upfront)
- Installation happens, system commissioned, and you’re done
Vouchers are time-limited, but with healthy budgets, availability remains strong in early 2026. Act sooner rather than later—demand spikes as awareness grows.
Pro tip: Ask installers about combining with insulation upgrades. Heat pumps shine brightest in well-insulated homes, and bundling can maximize efficiency (and savings).

Real Benefits: Why Switch Under Boiler Upgrade Scheme 2026?
Beyond the cash grant, the perks stack up quickly.
Lower running costs: Heat pumps often deliver 300-400% efficiency (for every 1kW electricity in, you get 3-4kW heat out). Many households see 30-50% bill reductions versus gas, especially with rising fossil prices.
Even heat and comfort: No more cold corners—consistent warmth throughout.
Eco impact: Massive carbon savings, aligning with UK net-zero goals.
Added value: Modern heat pumps boost property appeal and EPC ratings, potentially increasing resale value.
It’s like investing in a high-efficiency appliance that pays you back monthly through lower bills while quietly shrinking your environmental footprint.
Potential Challenges and Smart Tips
Nothing’s perfect. Upfront costs (even post-grant) can range £5,000-£15,000 depending on your setup. Outdoor units need space, and some homes require radiator upgrades or better insulation first.
Common hurdles:
- Noise from fans (modern units are quiet, but placement matters)
- Installation time (a few days to a week)
- Performance in very cold snaps (air-source models cope well down to -15°C with good design)
Smart moves:
- Prioritize insulation/draught-proofing first (often cheaper and amplifies heat pump gains)
- Get 3+ quotes from certified pros
- Consider solar PV pairing for near-zero electricity costs
- Check local noise regs and planning (permitted development usually covers ASHPs)
With good planning, most challenges fade, and long-term satisfaction soars.
How Boiler Upgrade Scheme 2026 Fits into the Bigger Warm Homes Picture
The BUS isn’t standalone—it’s a key pillar of the £15 billion Warm Homes Plan launched in early 2026. That plan pours £2.7 billion specifically into heat pump support via the BUS, plus billions more for low-income grants (up to full costs covered), loans, solar, batteries, and insulation.
For lower-income households, the Warm Homes: Local Grant or similar can top up or fully fund upgrades. Everyone else starts with the £7,500 BUS universal grant.
