How much does a heat pump cost for a park home? From £399, fully installed, once the new £9,000 Boiler Upgrade Scheme grant comes off the price. The £9,000 rate covers qualifying oil and LPG swaps and goes live from 21 July 2026, and your exact price is confirmed at a free survey before you commit to anything.
Heating with electric instead? You still qualify, at £7,500, so more of the cost stays with you. The offer itself lives on our park home heat pumps page; this article is about where the £399 comes from and why it is possible at all.
And the clock matters here. After 31 March 2027 the oil and LPG rate reverts to £7,500, and the budget inside the window is first come, first served. Every month of waiting is someone else’s application ahead of yours.
How an installed heat pump gets down to £399
There is no trick in the arithmetic. A park home needs a small, compact heat pump system, so the full installed price sits far below what a bricks-and-mortar house pays. Take £9,000 off a small number and what is left can be a very small number.
The grant is deducted before you pay, not posted back to you as a rebate. Your MCS-certified installer applies to Ofgem on your behalf, and you settle the balance that is left.
Why a park home costs so much less than a house
A heat pump for a typical house is sized against a big, leaky, multi-storey heat load, and the price reflects that. A park home is the opposite case: a small, single-storey, well-defined space that a compact unit handles comfortably.
The air source heat pumps we fit on park plots are built for exactly this. Trianco’s Activair range starts at 5 kW, runs on a standard single-phase supply, the same as every park home, and its high-temperature flow works with the radiators you already have, so there is no hidden rip-out of pipework and emitters lurking behind the headline price. It carries a 5-year warranty as standard, with the option to extend cover to 7 years.
The grant doing the heavy lifting
The £9,000 figure is the new top rate of the Boiler Upgrade Scheme, announced by the government on 26 June 2026 for off-gas-grid homes replacing oil or LPG heating. It goes live from 21 July 2026 and runs until 31 March 2027. The scheme itself carries on after that date; it is the £9,000 rate that ends. We covered the uplift announcement in detail when it landed.
| Heating in your park home now | Grant rate |
|---|---|
| Oil boiler | £9,000 from 21 July 2026, until 31 March 2027 |
| LPG boiler | £9,000 from 21 July 2026, until 31 March 2027 |
| Electric radiators or storage heaters | £7,500 |
Just as important for park homes is what happened in April. For years the scheme quietly locked park homes out, because applications needed an Energy Performance Certificate and most park homes have never had one. That rule was removed on 28 April 2026: under the current Ofgem scheme rules, a recent fuel bill and photos of your existing heating now count as evidence. The April overhaul of the scheme is worth a read if you were told “no” in the past, because the answer has changed.
The qualifying checks are short. Your park home must be your main residence on a residential-licensed site in England or Wales (holiday statics do not qualify, and in Scotland the route is Home Energy Scotland instead). You must be replacing oil, LPG or electric heating. And some parks have rules about outside units in the written agreement, which the survey checks for you.
What the price actually includes
One quote covers the whole job: the heat pump supplied and fitted, a room-by-room heat-loss design to MCS standards, installation and commissioning by certified engineers with the MCS certificate and handover pack on the day, the Ofgem grant application with the fuel-bill and photo evidence park homes need, the manufacturer’s warranty registered at handover, and an aftercare team afterwards for help with controls, the app, or a service visit.
That list matters when you compare quotes, because a £399 headline would be easy to fake by stripping things out of the job. Here it is the grant doing the work, not the spec sheet.
What it costs to run once it is in
Most park homes heat with electricity, LPG or oil, and all three are expensive ways to make heat. Electricity is the clearest case: on the Ofgem July to September 2026 price cap, direct electric heating costs around 26p for every kWh of heat, because one unit in is one unit out. A heat pump turns one unit of electricity into three or more units of heat, and the arithmetic follows.
Oil and LPG sit between those bars, cost less per unit than electricity but more than heat-pump heat, and both track global prices. If you want the full working, including what SCOP means on a real bill and the tariffs that push the numbers further apart, our guide to heat pump running costs goes through it line by line.
If your park has rules about outside units
Some written agreements restrict what can sit outside a park home. That is not a dead end. Trianco’s Activair indoor unit puts the entire heat pump inside the home, ducted through the wall, with nothing outside except two discreet air vents. It is about the footprint of a fridge-freezer, and it is MCS-certified and grant-eligible exactly like the outdoor version. Modern outdoor units are also much quieter than most people expect, which settles most park-rule conversations before they start. Either way, the survey checks your park’s rules for you.
Get your application in while the £9,000 is live
The maths of waiting is brutally simple, and it is the same heat pump either way.
Getting in the queue takes three steps and one signature. Tell us about your park home and current heating for a heat pump quote online, which takes a few minutes. An engineer then surveys the home, confirms whether your grant rate is £9,000 or £7,500, gathers the no-EPC evidence, and submits the Ofgem application. On installation day the system is fitted and commissioned, the warranty is registered, and you pay the balance with the grant already off the bill.
We install across mainland Britain, and the survey is free with no obligation, so applying early costs you nothing and missing the window costs you £1,500. If it is easier to talk it through first, call us free on 0800 222 9494. The £9,000 rate ends 31 March 2027 and the budget behind it is capped. Apply while the full amount is on the table.
