About This Service
Heat pumps designed around your home
We fit air source heat pumps in Coventry, each one sized from a room-by-room heat-loss calculation rather than a rule of thumb. We're heat pump installers based in Coventry, serving Balsall Common, Burton Green, Hampton in Arden and the surrounding area, and you can see every town we work in on our areas we cover page.
We use Vaillant and Worcester Bosch-approved heat pumps with weather-compensated controls, which adjust your heating to the weather so the system runs as cool, and as cheaply, as it can. Read how we sized the heat pump for Ian's bungalow to see why it matters.
There are four main types of heat pump, and the survey tells us which suits your home:
- Monobloc air-to-water: everything sits in the outdoor unit, which heats water for your radiators and hot water. The most common choice for UK homes.
- Split air-to-water: an outdoor unit linked by refrigerant pipes to a unit indoors, useful where space outside is tight.
- Air-to-air: indoor units blow warm air into each room, like air conditioning, and can cool in summer. They don't heat your hot water.
- Hybrid: a heat pump working alongside a gas or oil boiler, which takes over on the coldest days.
Air-to-water heat pumps qualify for the full £7,500 Boiler Upgrade Scheme grant and air-to-air for £2,500, but hybrids don't qualify.
Our Process
How It Works
Survey & Design
A qualified engineer surveys your home, works out the heat loss room by room and checks your walls, loft and windows. We then specify a heat pump, hot water cylinder and controls sized for your property.
Installation & Commissioning
We fit the outdoor unit, cylinder and controls and upgrade radiators where needed. Most homes take a few days. We then commission the system and register it with MCS, so you receive your certificate.
Aftercare & Support
We help with Boiler Upgrade Scheme paperwork, hand over controls, offer flexible service plans and provide priority call‑outs and parts deliveries for minimal downtime.

Costs and funding
What a heat pump costs, and help paying for it
We price each installation from the survey. The biggest factor is how much heat your home loses, because that sets the size of heat pump you need. The price also depends on:
- the heat pump's output in kW
- whether you need a new hot water cylinder or can keep yours
- how many radiators need upgrading, or whether you're adding underfloor heating
- the pipework, electrics and base for the outdoor unit
- whether it's a new build, as most new builds can't get the grant
We take the £7,500 Boiler Upgrade Scheme grant off your quote, so you never have to find it upfront. Homes heated by oil or LPG with no mains gas can get an extra £1,500 until March 2027. To see how we approached two real homes, read about our Financial Times feature. If you'd rather spread the cost, a loan is another option.

What our heat pump customers say on Google:
"Professional installation of our hybrid heat pump, in spite of the challenges of our old house. The guys arrived on time, were friendly and considerate during the installation and went out of their way to solve any issues. Communication with the company is very good." - Cathy, Google
"A fantastic group. Incredibly clued up on air source heat pumps, and backed by HeatGeek (which is where I found them for my install). They're investing in the right training to get everyone up to speed, and the entire crew that I met were brilliant: very helpful and a great laugh too. It's a new challenge in the industry, and they're rising to it. Very pleased, so thank you again" - Jon, Google
FAQ
Frequently Asked Questions
We carry out a full survey and detailed heat‑loss calculation that factors in insulation, glazing, occupancy and heating patterns. That determines the required kW output, cylinder size and whether radiator upgrades or underfloor heating are necessary to meet design temperatures.
A well-designed heat pump produces around three to four units of heat for every unit of electricity, while a gas boiler turns roughly nine-tenths of its gas into heat. Your bills depend on your electricity tariff, your insulation and the flow temperature (how hot the water sent to your radiators is). Larger radiators or underfloor heating let the heat pump run cooler, which keeps bills low.
Modern heat pumps are quiet. Most of the time you'll hear a low hum from the outdoor unit, and the fan gets louder only on the coldest days. We choose where the unit goes during the survey and check the noise level at your neighbours' windows, which planning rules require.
Often yes, but it depends on your property and radiators. Period homes with small radiators may need larger radiators or underfloor heating to reach the same room temperatures. We assess suitability and can design a hybrid system that keeps the boiler as backup if you prefer, but hybrids don't qualify for the Boiler Upgrade Scheme grant.
If you own your home and are replacing gas, oil, LPG or electric heating, an air-to-water heat pump can get £7,500 off. You no longer need an Energy Performance Certificate to apply, but most new builds don't qualify. As MCS-registered installers, we check your eligibility early and apply on your behalf.
