Air source heat pumps for homes and businesses in Chalfont St Peter
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems do not heat hot water, so you will need another way to do that. The work covers radiator systems, hot water cylinders and homes heated by oil, LPG or gas, and people most often call us about planning and permitted development questions and choosing between air-to-water and air-to-air.
For a house near Chalfont St Peter, space outside is rarely the problem, so the main questions are heat loss, radiators and the electrics.
Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

How the job changes from property to property
The Boiler Upgrade Scheme
The Boiler Upgrade Scheme covers England and Wales: £7,500 for air-to-water (and ground source), and £2,500 for air-to-air with strict conditions. The application goes through the installer.
Outdoor unit position and planning
Permitted development conditions in England include an outdoor unit of no more than 1.5 m³, compliance with MCS 020(a), and use for more than cooling alone. It can’t be within the curtilage of a listed building.

Air source heat pumps around Chalfont St Peter
Valuation Office Agency council tax records date about 42% of homes in Chalfont St Peter and the neighbourhoods around it to the post-war years, 1945 to 1972, and the 2021 Census found about 76% of households in detached or semi-detached houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder.
With Chenies Manor House about 4.8 miles north, it’s worth asking whether your own home is listed before planning a heat pump. Older homes near Parish Church of St Peter may need extra checks for planning and heat loss before a heat pump is designed.

Keeping the system healthy
So the system stays in good health:
- Seal draughts where you can
- Keep to regular servicing
- Keep the MCS certificate with the manufacturer’s paperwork
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Book a service every year. Your manufacturer’s warranty terms may say something about servicing.
Chalfont St Peter questions
Is Chalfont St Peter within the area you cover?
Yes, and the size of the place makes no difference to how we work. Send a few details and photos, and we reply the same working day.
Is a heat pump in Chalfont St Peter permitted development?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of Chalfont St Peter holds about 8 listed buildings and structures. 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 Buckinghamshire council, which is typically the planning authority for Chalfont St Peter.
How does the warranty work?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition, so keep your service records.
How do you keep the place clean during the work?
We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Which type of heat pump is right for my home?
The right choice depends on the property and what you need. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases, and we set out the options after the survey.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
How quickly will you reply?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
What happens on the day
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. So on the day, you don’t need a separate electrician for the electrical side. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Because we plan from pictures or a survey, a job in Chalfont St Peter can usually be finished in one visit.
- It starts with a conversation about the home, the existing heating and your plans.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Commissioning, MCS certification and a handover of the controls finish the job.
Getting ready for the visit
- Move furniture away from the wall where we will be working
- Mention any parking restrictions near the property
- Tell us about any building rules, permits or sign-in
How to get a quote
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. Add the address and what you’d like done, and many jobs can be priced from that.
Advice
Safe owner checks
On air conditioning, the filters in the indoor unit are normally the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
From one of our customers
“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.”
