The Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump. For some properties it pays £9,000. Both figures are indicative and confirmed at application.
The gap between them is £1,500, and it is the single most common thing to get wrong on an installer’s website — usually by being generous with it.
The rule, stated once
The uplift applies where the property is heated by oil or LPG and has no mains gas connection. Both conditions. Not either.
That sounds obvious written down, and it is misread constantly, because the two things feel like the same fact. They are not. Plenty of homes burn oil while sitting on a street with a gas main running under it — the previous owner never switched, or the tank was already there, or nobody could be bothered. Those properties heat with oil and are not off the gas grid.
Oil in the tank does not mean no gas at the boundary. One is what they burn; the other is what is available.
The uplift also ends on 31 March 2027. The scheme itself runs to 2030, so the £7,500 is not going anywhere. The extra £1,500 is.
What getting it wrong actually costs
Picture the survey. You are at the kitchen table, the homeowner has done their sums on £9,000, and you have to explain that the figure on your own website does not apply to their house. You are now £1,500 short on a quote they have already emotionally accepted, and the person who put the wrong number in front of them was you.
Very few jobs survive that. And it is entirely avoidable, because the question that settles it — “is there a mains gas connection?” — takes one line to ask.
The same logic applies to anything on a website that quotes a grant. A figure a homeowner cannot reproduce at the survey costs you the job at the worst possible moment, which is also the point at which you have already spent the diary time. It is the same failure mode as a solar saving that does not survive the kitchen table.
The one deadline worth advertising
Most urgency in this industry is invented. Schemes that have been “closing soon” for two years, and homeowners who have learned to ignore it.
This one is real and dated. If a household qualifies for the uplift and the work is not done by 31 March 2027, the extra £1,500 is simply not there. That is a sentence you can put in an advert and defend, and it is far more persuasive than anything you could make up — particularly to the oil-heated rural households who tend to think about heating in autumn and act in spring.
Where the border is
England and Wales only. Scotland runs its own scheme, and Northern Ireland is separate again.
Worth knowing if you work anywhere near the line: this is decided by local authority, not by postcode. CH, SY and HR postcodes straddle the border, so a postcode-only check gets it wrong in both directions — telling a Welsh household they cannot apply, and telling a Scottish one they can.
How to put this on a website without getting it wrong
The honest way to write it on a page is to lead with £7,500, mention the £9,000 as a condition rather than a headline, and state both conditions in the same sentence. That alone puts you ahead of most of the trade.
The better way is to stop stating figures at all and start resolving them. GrantCheck takes the postcode, resolves the property, and asks about the heating fuel and the gas connection separately — so nobody is ever shown £9,000 who cannot have it, and nobody is shown £7,500 when they were entitled to more. The enquiry that reaches you carries the answers they gave and the figure they saw, so the survey starts from the same page you do.
There is one more rule change worth checking on your site while you are in there: since 28 April 2026 a valid EPC is no longer required to apply at all. The 2026 rules in full are written up separately.

Grant figures on this page were checked against gov.uk on 30 August 2026 and are indicative — the binding figure is the one from the official application. Spotted something out of date? Tell us and we will fix it.
