How we handle air source heat pumps in Denham
Many air source heat pumps can be installed as permitted development in England, without a planning application. 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 look at the planning position for your home during the survey. If you are dealing with questions about the Boiler Upgrade Scheme and questions about where the outdoor unit can go, we can sort it out.
For a home around Denham 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.
The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Air source heat pumps around Denham
Roughly a third of a mile or less from central Denham, you reach the Denham Conservation Area. Draw a one-mile circle round the middle of Denham and it takes in 2 conservation areas. Church of St Mary, listed at grade I, is one of roughly 46 protected buildings and structures in the half-mile around Denham’s centre. Where a home is affected, the outdoor unit position is settled with the planning team at Buckinghamshire council, which usually handles Denham before the heat pump design is finished. At about 18 miles from central London, Denham sits inside the area we cover across London and the South East.
If your home is near Denham station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits. Older homes near Church of St Mary may need extra checks for planning and heat loss before a heat pump is designed.

Common questions in Denham
Do you cover smaller places like Denham?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Is the heat pump grant available in Denham?
Yes, the scheme covers homes in England, including Denham, if they qualify. The amount depends on the type of heat pump, and the survey confirms which applies. We hold MCS certification, so the application is ours to make for you.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
How soon will you get back to me?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
Do I need new radiators for a heat pump?
It varies from room to room. We check them all during the survey and the quote shows what’s needed.
Can I do any of the installation myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for breakdowns that can’t wait. Call 07833 053749 and tell us what’s happened.

Looking after it afterwards
To keep the system working properly:
- Do not block radiators or indoor units with furniture
- Seal draughts where you can
- Read the manufacturer’s warranty terms for your brand
Once commissioned, we register the installation with MCS and give you the certificate. Keep it with the manufacturer’s paperwork for future reference.
Keep radiators and indoor units unobstructed, as the system relies on them giving out heat.
What air source heat pumps can’t fix
A few issues sit outside what this work can do:
- Tax advice on your own circumstances
- Promising eligibility for the Boiler Upgrade Scheme
- Improving the building’s insulation
Not sure which it is? You can call 07833 053749 or email us and we will tell you honestly before you book.

The work itself takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. Work in Denham is booked in advance at a time that suits you.

Advice
Landlords, agents and facilities managers
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
For anyone managing more than one building, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so the files stay tidy.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
