Air Source Heat Pumps in Chesham
Air source heat pumps in and around Chesham, from a site survey or diagnosis to sign-off with the price fixed before work begins.
- Ageing boilers that will need replacing
- Deciding on the outdoor unit position
- Wanting to stop using oil, LPG or gas for heating
How we handle air source heat pumps in Chesham
We install air source heat pumps in Chesham and across Buckinghamshire, and we’re MCS certified. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We will explain which type fits your home and why. If the problem is a boiler that’s getting old and wanting to stop using oil, LPG or gas for heating, we can help.
Plenty of older homes in Chesham can run on a heat pump, sometimes with larger radiators or more insulation. The heat loss calculation shows what’s needed.
Each manufacturer sets its own warranty period. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Use the settings explained at handover
- Store the MCS certificate and warranty documents together
- Keep the outdoor unit clear all year
Handover includes the controls and how to get the best from a heat pump. Heat pumps tend to work best running steadily rather than in short bursts so we set the controls up with you.
A well-insulated home helps a heat pump, as lower heat loss means the system has less to do.
Signs you need air source heat pumps in Chesham
The Boiler Upgrade Scheme has made people ask whether their home could qualify. Whether you can get the grant depends on your home and the scheme conditions, so we check before you commit.
What we are most often called about:
- Checking emitters for a heat pump
- Plans to switch to electric heating with a heat pump
- An oil, LPG or gas boiler near the end of its life
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.
Comparing quotes
- Exactly what the price includes, from supply and fitting to commissioning
- Whether the quote is a fixed price
- How extra work would be agreed if they find something unexpected
How it works
The first job on site is protection: sheets over the floor and any furniture nearby and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes from a couple of days to around a week, depending on the system and how much of the heating changes, and we tidy up before we leave. Let us know about side gates, ladders or locked areas at your property in Chesham.
- It starts with a conversation about the home, the existing heating and your plans.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Preparing for the visit
- Make sure someone can let us in at the agreed time
- Find the manual or the paperwork for the system, if you have it
- Mention any roof access, ladders or high-level work
How to get a quote
The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and many jobs can be priced from that.

Homes in Chesham and heat pumps

With Cholesbury Manor House about 3.5 miles north-west, it’s worth asking whether your own home is listed before planning a heat pump.

Other services in Chesham
System by system
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger so we check them against each room’s heat loss.
Hot water cylinders
Hot water from an air-to-water system is stored in a cylinder. Space for the cylinder is part of the survey particularly in homes with a combi boiler.
Questions from Chesham
Can I fit a heat pump in Chesham without planning permission?
The answer turns on the property and where the outdoor unit would sit. The Chesham Conservation Area is close to the centre of Chesham. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Buckinghamshire council, usually the authority for Chesham.
Can you do air source heat pumps in Chesham?
We do: Chesham falls inside our working area. To start, phone us on 07833 053749 or drop us a line with a few pictures.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for breakdowns that can’t wait. Ring 07833 053749 any time and explain the problem.
How much time does a heat pump install need?
The work takes from a couple of days to around a week, depending on the system and how much of the heating changes. We confirm the timing after the survey, and you can call 07833 053749 or email us to book it.
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
Will skipping a service affect the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
What does an air-to-water heat pump cost?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. The heat pump size, radiator changes and the cylinder decide where in that range you are. Air-to-air is priced after a survey.
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
