The Boiler Upgrade Scheme: a plain guide for Darlington
£7,500 of public money is attached to each qualifying air source installation in England. Nobody asks what you earn. The installer, not you, deals with Ofgem, and the deduction has already happened by the time an invoice reaches you. Three things decide eligibility: an EPC with no outstanding insulation items, a certified installer, and a heating system running on gas, oil, LPG or direct electricity coming out.
What the scheme is, in one paragraph
The scheme, shortened to BUS by everyone in the trade, is how central government is paying to shift English homes onto heat pumps. Any qualifying air source system carries the same fixed sum, £7,500, regardless of the size of the house or the size of the bill. Payments began in 2022, and the pot behind them has since been topped up rather than pared back, with money committed well into the second half of this decade. Applied to a Darlington household the effect is not marginal. An £11,000 quotation becomes £3,500 in actual cash.
The conditions that actually bite
- The outgoing heating has to be fossil fuelled or direct electric. Gas boilers, oil boilers, LPG systems, storage heaters and panel heaters all count. Replacing an existing heat pump does not.
- The EPC must be current and carry no unactioned loft or cavity recommendations. This is the condition that catches most people out, and around Darlington the fix is generally cheap. Solid-wall terraces have no cavity to be recommended, so the loft alone usually clears it. Semis in Cockerton and Harrowgate Hill often need nothing more than a reassessment recording insulation that was fitted years ago.
- Both the contractor and the equipment need MCS certification. Without it there is no claim to make, which is why it is verified before any pricing happens through this site.
- The system must heat the entire property. That is the scheme insisting, in its own way, that genuine design work takes place.
- Owner-occupiers and small landlords both qualify. New builds and hybrid systems are excluded.
The route the money takes
You are never the applicant. Step by step: a survey happens, then a written price arrives with the funding already subtracted, then the system goes in, then it is commissioned and certified through MCS. At that point the installer lodges everything with Ofgem. Ofgem writes to you once, asking only whether the work genuinely took place at your address; you say yes; the £7,500 is settled with the installer. One email is the whole of your involvement. Nothing is ever paid out of your pocket and reclaimed later, which is where the word grant misleads people.
What it will not pay for
Hybrids sit outside the scheme entirely, which is why any hybrid quote issued here comes with a grant-funded full conversion priced beside it for a fair comparison. Heat pump to heat pump replacements are out. Properties that have already received a payment are out. And because of the EPC rule, some fabric work occasionally has to be completed first — the kind of thing that should surface at survey stage, not two days before an installation date.
Other support worth knowing about
Two further routes are relevant in this area. ECO4 is aimed at households on qualifying benefits or in vulnerable circumstances, and it funds insulation and heating measures — sometimes the very loft or wall work standing between a property and BUS eligibility. If your situation looks like it might qualify, the surveyor will point it out. VAT on heat pump installation is currently zero rated, an arrangement holding to 2027 at minimum, meaning the numbers on this website have no tax to be added afterwards. Anyone heating with storage heaters on the eastern estates, or with a kerosene tank in a DL2 village, ought to look at both routes together.
Common misunderstandings
Three come up repeatedly. First, people assume the grant is a voucher they have to chase; it is not, and they never handle it. Second, they assume a low income household gets more and a higher income household gets less; the payment is flat and income is never assessed. Third, they assume applying uses up some limited local allocation; the scheme is national, budgeted centrally, and being in Darlington neither helps nor hinders a claim.
The practical next step
Confirming eligibility is simply part of surveying a house: the certificate is looked up on the national register, the fabric is assessed on site, and the installer's registration is verified. Send the property details through the form and what returns is a price built around your address, with the funding already worked into it rather than a national average bolted on afterwards.
