At Limitless Energy, we believe in making renewable energy accessible, affordable, and stress-free for homeowners across South West Wales. Great news, at the moment there is a great opportunity the Boiler Upgrade Scheme (BUS)—a government-backed £7,500 grant designed to help households switch from fossil fuel boilers to low-carbon heating systems.
Let’s break it down.
✅ What Is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme (BUS) is a UK government grant that helps homeowners and small businesses switch from fossil fuel boilers to low-carbon heating systems like heat pumps.
The aim? Reduce your carbon footprint and lower long-term energy costs by moving away from gas, oil, direct electric or LPG boilers.
💸 What’s Available?
You can claim:
£7,500 off an air source heat pump
£7,500 off a ground source heat pump
£5,000 off a biomass boiler (in eligible rural areas)
This grant is paid after installation is complete—but don’t worry, we’ve made the payment process simple and stress-free.
🧾 How the Payment Process Works
At Limitless Energy, we use a phased payment plan to make the grant process transparent and easy:
25% deposit when you confirm your installation – this is fully insurance protected
35% payment just before work begins on site
40% final payment on completion. In most instances, we will have already applied to redeem your BUS voucher and so this is not payable.
Once your system is up and running, we handle everything with Ofgem, who then release the grant directly to us. In most cases, this completely covers your final bill—and you may even get money back, with customer credits ranging from £70 to £2,000, depending on system size. It’s like a clean energy cashback bonus!
