What we do

Full-service heat pump installs — from survey to switch-on.

Whether you're replacing an old gas boiler, going off-grid, or building new — we handle the whole job in-house. No sub-contracted labour, no vague "partners".

Air-source heat pump installation

Design, supply and fit — Daikin, Vaillant, Mitsubishi and Grant.

System redesign

Radiator sizing, pipework upgrades and buffer/cylinder specification — the boring bits that actually matter.

Hot water cylinders

Sized to your household, plumbed properly, with a smart controller you'll actually use.

BUS grant handled for you

Up to £7,500 off through the Boiler Upgrade Scheme. We do the paperwork, you get the discount.

Servicing & aftercare

Annual services, monitoring, warranty support — same engineers, all year round.

Solar / battery integration

Tie your heat pump into solar PV or a home battery so you're running on your own power where you can.

Wondering if your house suits a heat pump? Most do, some need work first. We'll survey it free and tell you straight either way.

What's included

Inside a heat pump install.

Most of it is already familiar — the same radiators, the same hot taps. What changes is where the heat comes from, and one cupboard you'll need to find.

1

Outdoor heat pump unit

The part that replaces your boiler. It sits outside on a slab, about the size of a washing machine, and takes warmth out of the outside air even in the middle of winter. Your old gas boiler and its flue come out completely.

2

Hot water cylinder

Hot water is stored rather than heated on demand, so the system needs a cylinder and somewhere to put it — an airing cupboard is ideal. It holds a full tank for baths and showers and reheats quietly through the day.

3

Radiators

The same radiators, in the same places. A heat pump warms the water more gently than a boiler, so we measure every room at survey and upgrade only the radiators that aren't big enough to keep that room warm.

4

Flow and return pipework

Two pipes do all the work: one carries warm water out to the rooms, the other brings it back to the heat pump to be warmed again. Usually your existing pipework, with any runs too narrow to carry the flow replaced.

5

Underfloor heating

A heat pump's ideal partner, but not a requirement. If you already have it, we'll run it. If you don't, there's no need to lift your floors — correctly sized radiators do the job just as well.

How it works

Sorted in four honest steps.

Heat pumps aren't a boiler swap — but we've made the process as painless as we can. No pressure calls, no upselling.

01

Free home survey

We visit, take heat-loss measurements and talk you through your options in plain English.

02

Fair, fixed quote

Full written design and price, usually within a week. BUS grant already deducted.

03

Tidy install

Our own team, typically 2–5 days on site. Old kit removed, no mess left behind.

04

Commissioning & aftercare

We stay involved — first-year check-in, ongoing servicing and warranty support on the same number.

Boiler Upgrade Scheme
£7,500* off your installation, taken straight off the quote — not claimed back later. We handle the BUS application and the paperwork, so you never fill in a form.

*£9,000 if your property is heated by oil or LPG and has no mains gas connection — the £7,500 grant plus a £1,500 uplift, available until March 2027. One grant per property, and hybrid systems aren't eligible. We'll confirm exactly what yours qualifies for at the free survey, before you commit to anything.

Common questions

Straight answers on heat pumps.

Will a heat pump actually keep my house warm in a UK winter?

Yes — a properly-sized heat pump keeps a UK home warm at outside temperatures well below zero. The trick is the sizing and the radiators, not the pump itself. That's what we spend most of our survey on.

Do I need to rip out all my radiators?

Not usually. Most homes need one or two radiators upgraded to slightly larger ones — not the whole system. We tell you exactly which at survey and it's part of the fixed quote.

How much does it cost after the BUS grant?

Most of our installs come in between £8,000 and £14,000 after the £7,500 grant — depending on the size of the home and how much pipework needs upgrading. We'll never give you a price without seeing the property.

How long does the install take?

Two to five days on site for a typical home. We aim to keep you in hot water the whole time, and we won't leave the site until the system is running, commissioned and you're happy with it.

Are heat pumps noisy?

Modern units run at around 40–50 dB from a metre away — quieter than a fridge. We position the outdoor unit sensibly and can add acoustic shrouds where planning or neighbours are a concern.

Can I keep my gas boiler as backup?

We usually recommend against it — a well-sized heat pump doesn't need one, and hybrid setups add cost and complexity. But if it makes sense for your home we'll design that too.
