What the Boiler Upgrade Scheme actually is

The Boiler Upgrade Scheme (BUS) is a UK Government grant administered by Ofgem. It currently pays £7,500 toward an air-source heat pump install (or a ground-source heat pump or biomass boiler under separate caps) in England and Wales.

It's property-based, not income-based — you don't fill in a means test. It's available to homeowners and private landlords replacing fossil-fuel heating (gas, oil, LPG, electric resistance) with a heat pump. The grant runs until at least 2028 under current government commitments, but rates and eligibility can be reviewed.

What you actually need to qualify

The eligibility criteria are clearer than they first look. To qualify, you need:

  • A property in England or Wales (Scotland has its own scheme).
  • A fossil-fuel or electric-resistance heating system being replaced (the grant doesn't apply to second heat pumps replacing first heat pumps).
  • A valid Energy Performance Certificate (EPC) with no outstanding loft- or cavity-wall-insulation recommendations (exemptions apply for certain properties).
  • An installer accredited under the Microgeneration Certification Scheme (MCS) to handle the application on your behalf — this is a scheme requirement, not a Thermova claim.

Most three-bed Lancashire semis qualify. If your EPC is missing or out of date, or it has open insulation recommendations, we'll flag this at the survey and tell you what to clear first.

How Thermova handles the grant route

You do not interact with Ofgem. We handle the application, attach it to your install, and the £7,500 is deducted directly from your invoice — not paid to you afterwards.

How the Thermova BUS process works
1. Eligibility checkWe check your EPC and property type at the first survey — no charge.
2. Heat-loss designSystem designed around your property; quote includes the gross price and the net-of-grant price.
3. Voucher applicationWe submit the BUS voucher application to Ofgem on your behalf.
4. InstallWe install once the voucher is in place. Typical timeline: 4–8 weeks from voucher to commissioning.
5. Grant deduction£7,500 deducted from your final invoice. You only pay the net amount.
6. Voucher redemptionWe submit redemption paperwork. You do nothing further.

Why grant timing matters

The £7,500 rate is currently the highest the scheme has paid since launch — it rose from £5,000 in 2023. Grant rates are reviewed periodically by Government. While there's no announced cut, the size of the rate plus its political profile means it's the kind of policy that can change with a fiscal event. The safest assumption is that the current rate will not last forever.

There's also voucher demand to consider — peak install seasons (autumn into early winter, when boilers fail) see installer capacity tighten. Earlier in the year usually means more flexible install dates.

How Thermova differs from a BUS-eligible install elsewhere

  • Net price on the invoice, not a reimbursement. The grant comes off the bill — you pay only the net.
  • EPC clearance support. If your EPC blocks the grant, we can route you through our EPC C compliance service first.
  • Founder-led, no commission-driven sales pitch. Graham personally signs off your design.
  • Measured outcomes. Our public Lytham case study shows the year-one SCOP and CO₂ reduction in real numbers.

Frequently asked questions

Is the £7,500 grant means-tested?
No. The Boiler Upgrade Scheme is property-based. Your income is not assessed. It's available to eligible homeowners and private landlords in England and Wales replacing fossil-fuel heating.
Do I get the money or does it come off the price?
It comes off the price. Thermova handles the application and the £7,500 is deducted directly from your invoice — you pay only the net amount. You don't have to wait for a refund.
What if my EPC has open recommendations?
If your EPC shows outstanding loft- or cavity-wall-insulation recommendations, those usually need to be addressed (or exempted) before the BUS voucher is issued. We'll tell you what's blocking the grant at the first survey, and route you through our EPC C compliance service if appropriate.
Can landlords claim the £7,500?
Yes. Private landlords are eligible on the same terms as homeowners, provided the property meets the criteria. The grant attaches to the property, not the tenant. See our landlord services page for portfolio sequencing.
How long does the BUS process take?
Voucher applications are typically issued within two to four weeks of submission. Install usually follows within four to eight weeks of voucher issue, depending on installer availability and any preparatory works.
What happens if the grant rate changes?
Your install is locked to the voucher rate in force at the time the voucher is issued. If government cuts the rate after your voucher is issued but before you've commissioned, you still get the higher rate. The exposure is the other way — delaying could mean a smaller grant if rates fall.
