The Boiler Upgrade Scheme (BUS) is a government initiative designed to help homeowners replace fossil fuel heating systems (like gas or oil boilers) to clean, low-carbon alternatives. Historically focused on supporting heat pumps, the Boiler Upgrade Scheme 2026 is set to expand, offering a boiler upgrade scheme grant for heat battery systems, including tepeo’s ZEB.
From winter 2026, eligible homeowners will be able to apply for a £2,500 boiler upgrade scheme grant when installing a heat battery. By lowering installation costs and encouraging the adoption of clean heat, the grant plays a crucial role in reducing carbon emissions, improving energy efficiency and supporting the UK’s transition to net zero – while delivering long-term comfort and sustainability for properties nationwide.
You may qualify for the boiler upgrade scheme if:
Heat batteries will be included in the Boiler Upgrade Scheme from as early as winter 2026, once regulatory requirements are complete.
To make the transition accessible now, tepeo is offering a proactive £2,500 early grant match off every ZEB Heat Battery Boiler, so you can upgrade today without waiting for official grant release.
The Boiler Upgrade Scheme can be an effective way to reduce the cost of switching to low-carbon heating, especially if you’re looking to replace an old gas, oil or electric boiler with a more sustainable solution.
With the Boiler Upgrade Scheme due to expand to include heat batteries as early as winter 2026, more homeowners will soon be eligible for support. However, you don’t need to wait to start enjoying the benefits of low-carbon heating.
To help homeowners begin the transition sooner, tepeo is currently offering £2,500 off the upfront cost of a ZEB Heat Battery Boiler, matching the proposed boiler upgrade scheme grant. This enables you to:
The Boiler Upgrade Scheme can be worth it for many, but the best timing and approach will depend on your home, your budget, and what works for your needs, whether that means using a government grant in the future or making the switch to a suitable alternative today.
You don’t need to apply for the Boiler Upgrade Scheme yourself, your certified installer will handle the entire process for you.
If your property is eligible and you wish to upgrade to a heat battery with tepeo, here’s how the process will work when it comes into effect later in 2026:
Unlike heat pumps, heat batteries are designed to work like a direct replacement for your boiler, without major changes to your home.
