In this video, heating engineer Tulloch Priest outlines the latest updates to the UK Boiler Upgrade Scheme (BUS) that take effect from July 2026 and run through 2030. The key changes include a new £9,000 grant for oil and LPG‑fueled homes, the removal of the mandatory Energy Performance Certificate (EPC) requirement (replaced by a recent utility bill and photos as evidence), and the addition of air‑to‑air heat pumps as an eligible technology with a £2,500 grant alongside the existing £7,500 for air‑to‑water and ground‑source heat pumps. The scheme now formally requires installers to hold MCS certification and be members of the Consumer Code (or hold the MCS customer commitment). Priest highlights the business opportunity these changes create, noting that a standard boiler swap typically earns £1,500‑£3,000 while a heat‑pump install can bring £4,000‑£8,000, and the larger grant makes the customer’s cost more affordable. He advises engineers to obtain MCS accreditation, identify existing oil/LPG customers, capture photos and utility bills on site, and use Gas Engineer Software for automated record‑keeping. The video concludes with a call to action to follow the step‑by‑step guide, take advantage of discounted training, and consult the description links for full details.

Chapters

There's a new £9,000 grant coming in July for oil and LPG homes. The EPC requirement is gone and the scheme has been extended to 2030. That's right, the Boiler Upgrade Scheme has just been updated and it's the biggest shake-up since launch. And for heating engineers, this is a genuine business opportunity. The rules around eligibility, paperwork, and technology have already changed from the 28th of April, so stay tuned to find out what the actual differences are and what it really means for your business. First, properties no longer need a valid Energy Performance Certificate to qualify. Where there isn't one, you'll provide alternative evidence, usually a recent utility bill plus photos of the existing heating system. This was the single biggest reason quotes used to fall over, so it's a real win. Secondly, air-to-air heat pumps are now eligible with £2,500 per domestic install alongside the existing £7,500 for air-to-water and ground source. Thirdly, MCS certification is now formally written into the rules. To install under the scheme, you need to be MCS certified with a Consumer Code membership or the MCS customer commitment alongside it. And from July 2026, oil and LPG homes will get a £9,000 grant. This is an additional £1,500 increase from before. With the scheme extended to 2030, a budget increase, and the Future Homes Standard, the direction that the industry is heading in is clear. Engineers who get their accreditations and admin sorted now will have a real edge over the next 4 years. And the numbers stack up too. A standard boiler swap might earn you between £1,500 and £3,000, but a heat pump install can bring £4,000 to £8,000. And the BUS grant means the customer's cost feels more accessible. So what do you do next? If you're considering MCS, our step-by-step guide walks you through the process and typical timelines. Gas Engineer Software customers are also eligible for discounted training on Logic for Training. If you have them, identify the oil and LPG customers already in your books. Those are the people to start the heat pump conversation with as we move through 2026. And when you're on site for any boiler job, take photos of the unit and any oil or LPG tanks, and grab a copy of a recent utility bill if the customer's happy for you to attach it all to the job records so the evidence is there when you need it. Under MCS, every install needs to be properly recorded and your paperwork has to stand up to audit. Gas Engineer Software automatically attaches records, certificates, and photos to each job, so when the auditor comes calling, it's all in one place.
