Air source heat pumps

Warm, quiet, low-carbon heating for your home

An air source heat pump moves heat from the outside air into your home, using electricity to upgrade low-grade heat into comfortable, steady warmth.

  • Works with radiators and underfloor heating
  • Runs steadily rather than on/off like a traditional boiler
  • Designed, installed and commissioned by our in-house team
How it works
1
Outside air
Even on cold days the outside air holds usable heat energy that the system can collect.
2
Heat pump
The heat pump uses a refrigerant cycle to upgrade this low-grade heat to a higher temperature.
3
Your home
That upgraded heat is delivered into your radiators or underfloor system as gentle, steady warmth.
In simple terms, the heat pump moves heat from the air outside and concentrates it so your home can be warmed efficiently with electricity.
02 • Is it right for you?

Is your home a good match for a heat pump?

Not every home is perfect for a heat pump, and that’s okay. Our job is to be honest about where it works well and where it might not be the best option.

The cards on the right describe the kinds of homes that tend to see the best results. If a few of them sound like you, there’s a good chance a heat pump could be a strong fit.

A

Decent insulation & windows

Homes with reasonable insulation and double-glazing make it easier for a heat pump to run efficiently and keep rooms at a steady temperature.

B

Space outside for a unit

You have somewhere for the external unit to sit – often a side path, garden or flat roof – where it won’t get blocked or boxed in.

C

Boiler due for replacement

Your current gas or oil boiler is ageing, unreliable or due for replacement in the next few years, so you’re thinking about long-term options.

D

Comfort over very hot radiators

You’re happy with gentle background warmth and rooms that feel consistently comfortable, rather than radiators that cycle between very hot and cool.

If three or more of these sound like your home, a heat pump is often a strong option. If you’re unsure, send us a few details and we’ll give an honest view.

We also install other manufacturers’ heat pumps where they’re a better fit for your property or project. The right choice depends on your home, existing system and priorities.

04 • How we work

From first chat to warm, steady heating

We don’t just swap a boiler for a heat pump. We design the whole system around your home so it can run efficiently and comfortably, not just on paper. Every project follows a clear process with our in-house team.

1
Initial conversation & information

We start with a call and some basic details about your home: photos, floor area, current heating system and bills, plus any future plans or extensions.

2
Heat loss calculations & design

We carry out room-by-room heat loss calculations and design the system – including pipework, flow temperatures and whether any radiators or emitters need upgrading.

3
Installation & commissioning

Our own installers fit the heat pump, make any system changes, and commission it to run as designed. We work to minimise disruption while we’re on site.

4
Handover, controls & follow-up

We show you how to use the controls, set schedules and adjust temperatures – and we check in after the first heating season to make sure everything is behaving as expected.

05 • Questions

Air source heat pump FAQs

Heat pumps can feel new if you’ve lived with boilers for years. These are some of the most common questions we’re asked when people are first exploring the idea.

A well-designed system will keep your home comfortably warm, even when it’s cold outside. The key is matching the heat pump and emitters (radiators or underfloor) to your home’s heat loss so it can run steadily rather than always “chasing” the temperature.
In many homes, some existing radiators are fine and others benefit from being upsized. As part of our design work we assess each room and recommend which emitters can stay as they are and which ones should be replaced for the best comfort and efficiency.
Modern air source heat pumps are designed to run quietly, especially at typical operating levels. We consider noise in our design – including where we locate the unit and how it’s mounted – so it’s unobtrusive for you and your neighbours.
It depends on your current fuel, tariffs, insulation and how the system is designed. A good heat pump can deliver multiple units of heat for each unit of electricity it uses, which can be competitive with gas and usually much better than direct electric or oil. We can talk through likely running costs for your specific home.
For a typical home, installation usually takes several days, depending on how much of the existing system needs altering. We’ll give you a clear timeline before we start and plan the works to keep disruption as low as possible.
