Replacing an oil boiler? Your grant rises from £7,500 to £9,000, so take a further £1,500 off every after-grant figure above. That's how compact oil swaps start from £1,999.

Solid-wall properties add around £400 for the extra design work. Radiator upgrades, where needed, are priced individually at the free survey.

Every price includes everything

One installed price. Not a unit price with the real costs added later.

What's in the price

  • The heat pump unit
  • Hot water cylinder
  • All labour, typically 2–5 days
  • Pipework and electrical work
  • Commissioning and handover
  • MCS certification
  • Full grant application, handled by us
  • Scaffolding where needed

Our last three installations, real prices

£12,200. £13,300. £14,500. Those are the actual before-grant prices of the last three systems we installed, not a teaser rate that grows at survey. If a quote looks dramatically cheaper, check what it leaves out: the cylinder, the radiators, the heat loss design, or the paperwork.

Our online estimate uses the same pricing model, so the number you get in 60 seconds is the number we stand behind at survey.

What about running costs?

The install price is half the story. Here's the other half.

£500–£1,300 saved yearly

Heat pumps are 300% efficient: for every 1kW of electricity, you get 3kW of heat. Typical savings of £500–£1,300 a year against gas, oil, or LPG.

20+ year lifespan

Nearly double a gas boiler. Less maintenance, no annual gas safety checks, fewer breakdowns. The install cost spreads over a much longer life.

0% VAT until 2027

Heat pump installations are VAT-free. That's a saving of up to £2,000 on a typical installation, already included in every price on this page.

Your estimate includes a running cost projection for your property, compared against what you pay now.

The grant does the heavy lifting

The Boiler Upgrade Scheme pays £7,500 towards your heat pump installation, or £9,000 if you're replacing an oil boiler. It's how a £13,000 installation becomes £5,500, and a compact oil swap can start from £1,999.

We apply on your behalf, chase Ofgem, and deduct the grant from your invoice. You never have to claim it back yourself.

Cost questions, answered straight

The things people actually want to know about heat pump prices.

How much does an air source heat pump cost for a 3-bed house?
For a typical 3-bed semi in Dorset, Hampshire or Wiltshire, a fully installed air source heat pump costs £11,500 to £14,500 before the grant. With the £7,500 Boiler Upgrade Scheme grant that's £4,000 to £7,000. Replacing an oil boiler? The grant rises to £9,000, taking a further £1,500 off, which is why most of our customers pay between £2,000 and £5,000.
Why are some online quotes so much cheaper?
Teaser quotes usually price the heat pump unit and little else. A proper installation includes the hot water cylinder, full heat loss design, pipework, electrical work, commissioning and MCS certification. Our prices include all of it: the last three systems we installed came to £12,200, £13,300 and £14,500 before the grant, and that is what they actually cost.
Is the "from £1,999" price real?
Yes, with the conditions stated plainly: it is a compact property replacing an oil boiler, which qualifies for the £9,000 grant. With the standard £7,500 grant, installations start around £3,000 after grant. Across all our jobs, most customers pay between £2,000 and £5,000.
What makes the cost go up?
Four things: the size of the heat pump your home needs, the hot water cylinder size, solid walls (around £400 extra for the additional design work), and any radiators that need upsizing, which we price individually at the free survey. There are no hidden extras beyond these.
What does the price include?
Everything: the heat pump unit, hot water cylinder, all labour, pipework, electrical work, commissioning, MCS certification and the full grant application. Scaffolding is included where needed. 0% VAT applies to the whole installation.
What are the running costs?
Heat pumps are around 300% efficient: every 1kW of electricity produces 3kW of heat. Typical households save £500 to £1,300 a year compared with gas, oil or LPG heating. Our estimate includes a running cost projection for your specific property.
Do I qualify for the BUS grant?
Most homeowners qualify. You need a valid EPC (we can arrange this), and the property must not be a new build. The grant is available for owner-occupiers, private landlords, and self-builders. We check your eligibility during the free survey and handle the whole application.
