Back to eligibility check

Every winter, hundreds of thousands of homeowners across Norfolk, Suffolk, Cambridgeshire and Essex do the same thing: they call their oil supplier, arrange a delivery, and quietly absorb a cost that their neighbours on mains gas simply don't face. The oil boiler in the outhouse hums along. The bills arrive. Life continues.

What very few of those homeowners know is that the government has set aside significant funding specifically to help them replace that oil boiler — and that the grant available to off-grid homes is larger than the standard figure you may have seen reported: not £7,500, but £9,000.

It is called the Boiler Upgrade Scheme Oil and LPG Uplift. It is administered by Ofgem. It has been running since 2022. And in a region where Mid Suffolk alone has 30.3% of homes heating with oil — ten times the national average — the number of eligible homeowners who have never heard of it is, frankly, remarkable.

"Seven of the ten English districts with the highest oil-only heating rates are in the East of England. The grant was designed for exactly this region."

Why the East of England matters most

The ONS Census 2021 data on domestic heating is striking when mapped against the Boiler Upgrade Scheme. The East of England is not simply an area with above-average oil heating — it is the single largest concentration of oil-dependent homes in England.

Norfolk has over 30% of properties off the gas grid entirely. Suffolk's overall oil-only rate sits at 13.2% — four times the national average. Parts of rural Cambridgeshire and Essex follow similar patterns. These are not marginal statistics. They represent tens of thousands of households paying significantly more for their heating than they need to, unaware that substantial public funding exists to help them switch.

Off-grid heating in the East of England

  • Mid Suffolk: 30.3% oil-only — highest rate of any district in England
  • Suffolk overall: 13.2% oil-only — four times the national average of 3%
  • Norfolk: over 30% of all properties are off the gas grid entirely
  • East Anglia average: 23%+ off-grid across the region
  • 7 of the 10 highest oil-only districts in England are in the East of England (ONS Census 2021)

What the grants actually cover

The Boiler Upgrade Scheme is the primary funding mechanism, but it is not the only one available to East of England homeowners. Understanding the full grant landscape — and how schemes can be combined — is where significant savings are found.

Scheme Value Who qualifies Expires
BUS Oil/LPG Uplift £9,000 Homeowners replacing oil or LPG heating — England & Wales March 2028

ECO4 Fully funded Low income / qualifying benefits + EPC D–G property Check current phase
Norfolk Warm Homes Additional local top-up Norfolk residents — stackable with BUS Check deadlines
Suffolk Warm Homes Additional local top-up Suffolk residents — stackable with BUS Check deadlines
CERP Cambridgeshire Community grant Cambridgeshire homeowners via local authority Check deadlines
Grant stacking — the angle most homeowners miss Norfolk and Suffolk homeowners may be eligible to combine the BUS Oil/LPG Uplift (£9,000) with their respective local authority Warm Homes grant. An MCS-certified installer can confirm whether both apply to your property — in some cases, the combined funding reduces the net installation cost to a fraction of the list price.

How the scheme actually works

The process is more straightforward than most people expect. The Boiler Upgrade Scheme is installer-led: once a qualified, MCS-certified heating engineer has assessed your property and confirmed eligibility, they apply for the grant on your behalf. The money is deducted from your installation invoice — you never see it pass through your account.

There is no auction, no waiting list, and no means test for the standard BUS grant. Eligibility is determined by property type, current heating system, and EPC status. The scheme runs until March 2028, but vouchers are issued on a first-come, first-served basis and budgets are finite.

What does a heat pump actually cost in the East of England?

A typical air source heat pump installation in a detached or semi-detached property in Norfolk or Suffolk runs between £9,000 and £16,000 before the grant. After the £9,000 oil/LPG uplift, the net cost to the homeowner starts from zero in some cases — and rarely exceeds £7,000 for a standard property.

Running costs depend heavily on tariff choice, insulation quality, and system design. Homeowners on dedicated heat pump electricity tariffs — several of which are now available from major suppliers — are reporting annual heating bills comparable to, or lower than, their former oil costs. The historic "spark gap" between electricity and gas prices is narrowing.

A note on eligibility Not every property will qualify, and it is worth understanding the key criteria before investing time in the process. You must be the homeowner (not a tenant). The property must be in England or Wales. Your EPC must not carry outstanding loft or cavity wall insulation recommendations that have not been addressed. Listed buildings and some flat types require additional assessment. The eligibility check below will give you a clear picture in under two minutes.

The content gap in this region is significant. Search for "oil boiler replacement grant Norfolk" or "Suffolk heat pump funding" and you will find government pages, installer sales pitches, and very little independent, factual guidance. This piece exists to fill that gap — and to make sure that homeowners in one of England's most oil-dependent regions are not the last to know that substantial public funding is available to them.

The first step is simply finding out whether your property qualifies. It takes less than two minutes, costs nothing, and commits you to nothing.
