Boiler Upgrade Scheme Guide
"Boiler Upgrade Scheme" is a genuinely confusing name for homeowners searching for help with a gas boiler replacement, because the scheme is not about boiler-to-boiler upgrades — it's a grant that supports moving away from a fossil-fuel boiler to a heat pump. We'd rather explain that clearly upfront than let the name imply something we don't offer through it.
Quick answer
The government's Boiler Upgrade Scheme is a grant toward installing a heat pump (or, in limited cases, biomass boiler) to replace a fossil-fuel heating system — it does not fund a like-for-like gas boiler replacement. If you're specifically replacing a gas boiler with another gas boiler, this scheme does not apply to that job.
What the scheme actually funds
The Boiler Upgrade Scheme provides a grant toward the cost of installing an air source or ground source heat pump (and in some cases a biomass boiler) in place of a fossil-fuel heating system, administered in England and Wales through Ofgem. It is aimed at the switch away from gas, oil or LPG boilers, not at replacing one gas boiler with a newer gas boiler.
If you're replacing a gas boiler with another gas boiler
A straightforward gas-to-gas replacement — which is what most of our new boiler installation, combi replacement and system replacement work covers — sits outside this scheme's scope. There's no current grant scheme specifically subsidising like-for-like gas boiler replacement in the way the Boiler Upgrade Scheme subsidises heat pumps.
If a heat pump is something you're considering instead
If you're weighing up a heat pump against a gas boiler replacement rather than assuming gas is the only option, the Boiler Upgrade Scheme is genuinely relevant — but heat pump suitability depends heavily on your property's insulation, radiator sizing and space for external equipment, which is a different assessment to a gas boiler survey. We install and quote gas boiler replacements; for heat pump-specific advice, an MCS-certified heat pump installer and the official government scheme guidance are the right starting points.
Why the name causes confusion
The name 'Boiler Upgrade Scheme' is a significant source of confusion for many homeowners. When people search for this term online, they are typically looking for help or financial support to replace their existing gas boiler with a newer, more efficient gas boiler. They are often surprised to find that the scheme is not for that purpose at all, but is instead a government grant specifically designed to help fund the removal of a fossil-fuel boiler and its replacement with a low-carbon heating system like a heat pump.
This mismatch between the common search intent and the scheme's actual purpose means many people discover the grant is not relevant to their immediate plan for a like-for-like gas boiler replacement. It is important to understand that eligibility for the scheme and the potential grant amount are not fixed and should be checked directly against the latest official government and Ofgem guidance. The details can change, so relying solely on general search results or the scheme's name can be misleading.
What to check before assuming you're not eligible for any support
The Boiler Upgrade Scheme's specific criteria may mean it does not apply to your situation, but it is important not to assume this means there is no other support available. Government initiatives, energy supplier obligations, and local authority programmes can change, and new offers may be introduced. The official GOV.UK website and Ofgem's pages are the primary sources for the most current and accurate information on all national schemes.
Before concluding you have no options, it is also worth speaking directly with qualified heating installers. A reputable installer should be informed about the broader landscape of support, including any temporary local grants, energy supplier incentives, or manufacturer promotions that could help offset costs. They can provide practical advice on what might be applicable to your property and heating system.

Frequently asked questions
Can I get a grant for a new gas combi boiler?
The Boiler Upgrade Scheme specifically does not cover like-for-like gas boiler replacement — it funds heat pump installation instead. There is no equivalent national grant scheme currently subsidising standard gas boiler replacement.
What's the difference between a gas boiler replacement and a heat pump installation?
A gas boiler replacement swaps one gas-fired appliance for another, usually reusing much of the existing radiator and pipework setup. A heat pump installation is a bigger change — it typically needs larger radiators or underfloor heating and outdoor space for the unit, and is assessed differently to a boiler survey.
Who administers the Boiler Upgrade Scheme?
It's a UK government scheme administered through Ofgem, covering England and Wales. Scotland has separate support schemes for low-carbon heating. Check the current official guidance for up-to-date eligibility rules, as government scheme details change.
Should I get a heat pump instead of replacing my gas boiler?
That depends on your property's insulation, existing radiators, available outdoor space and budget — it's a genuinely different assessment to a gas boiler survey. We're specialists in gas boiler replacement; for heat pump suitability, speak to an MCS-certified heat pump installer.
Are there any other grants for gas boiler replacement?
Support has existed at various times for low-income or vulnerable households (such as ECO scheme funding), with eligibility rules that change — worth checking current government and energy-supplier schemes directly rather than assuming a headline scheme name applies to your situation.
