Chalfont Common questions
Is Chalfont Common within the area you cover?
Yes. Chalfont Common is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Can I get the Boiler Upgrade Scheme grant in Chalfont Common?
Yes, if the home and the heat pump meet the scheme’s rules: Chalfont Common is in England, where it applies. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. As an MCS certified installer, we apply for it on your behalf.
Is the equipment covered by a warranty?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.
When will I hear back?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
How much does an air source heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales though not every home qualifies.
Which brands do you work with?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Will I get records for the system?
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.
How we handle air source heat pumps in Chalfont Common
In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. The work covers underfloor heating, homes heated by oil, LPG or gas and air-to-air heat pumps, and common reasons people get in touch are planning and permitted development questions and deciding on the outdoor unit position.
For a home around Chalfont Common that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

How we price air source heat pumps
The survey or diagnosis tells us what the work involves. The main factors are:
- Whether it’s a simple split or a larger system
- How easy the units are to reach
- The distance and route between the indoor and outdoor units
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we’ll go through it with you.
Before you get in touch
You don’t need the technical terms. Just send:
- Photos showing the indoor unit and the space around it
- Where the outdoor unit is, or where you’d like it
- A close-up of the unit’s label showing the model number
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and many jobs can be priced from that.
How the visit works
We book the visit for a day and time that suit you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the pictures you sent. If something is different, we talk it through with you before carrying on. After that, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Seeing the property in photos first means the trip to Chalfont Common can be planned properly.
- We start with your plans and the property.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We recommend air-to-water or air-to-air and check the grant position.
- The system is installed and connected to the controls.
- We commission it, complete the MCS certificate and show you how to use it.
Preparing for the visit
- Mention any managing agent or landlord rules we need to follow
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Arrange for someone to be there to let us in

What air conditioning won’t do
We will not sell you work that doesn’t address the problem, so here are the limits:
- Planning approval where permitted development doesn’t apply
- Improving the building’s insulation
- Disconnecting or servicing a gas boiler
If in doubt, ring 07833 053749 or fill in the contact form and we’ll say what we think.
Parts of the system we cover
- Underfloor heating
- Radiator systems
- Air-to-water heat pumps
- Hot water cylinders
- Air-to-air heat pumps
- Homes heated by oil, LPG or gas
Safe owner checks
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and give us a ring on 07833 053749 or send an email.
Air source heat pumps around Chalfont Common
VOA council tax data date about 45% of homes in the Chalfont Common area to the post-war years, 1945 to 1972, and about 75% of households live in detached or semi-detached houses, according to the 2021 Census. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. Historic England lists about 7 buildings and structures within half a mile of the centre of Chalfont Common, including Water Hall (grade II). For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with the planning team at Buckinghamshire council, which typically handles Chalfont Common where necessary.
With Chenies Manor House about 3.8 miles north, it’s worth asking whether your own home is listed before planning a heat pump. If your home is one of the older properties near St Paul's, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
