The BUS Scheme and tepeo's early grant match

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:

• You own your own home
• You are replacing a fossil fuel heating system
• Your property meets basic energy efficiency requirements

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.

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:

Upgrade to low-carbon heating right away
Start seeing reductions in your energy bills sooner
Avoid waiting for government funding to become available
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:

1. Start with the tepeo Home Check
   Begin by completing our quick Home Check. This tool helps you see if your home is suitable for a heat battery and confirms your boiler upgrade scheme eligibility.
2. Find an approved installer
   Once your property is confirmed as a good fit, we will help connect you with an MCS-certified installer in your area, which is essential for accessing the boiler upgrade scheme grant.
3. Receive your quote
   Your installer will assess your home and propose the most suitable low-carbon heating solution.
4. Installer applies for the grant
   They’ll manage the boiler upgrade scheme application for you, taking care of the paperwork so you don’t have to, when the scheme becomes available.
5. The grant is deducted upfront
