Air source heat pumps in Little Marlow
Many air source heat pumps can be installed as permitted development in England, without a planning application. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit cannot be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. Typical jobs include questions about where the outdoor unit can go and planning and permitted development questions, on underfloor heating, hot water cylinders and air-to-water heat pumps.
For a home around Little Marlow that’s off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Managing agents and facilities teams in Little Marlow
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.
If you look after several properties, we can plan visits across the portfolio and price them together. Each property gets its own records, so each one has its own history.

Existing cylinders may not be suitable for a heat pump and we tell you if it needs replacing.
The Boiler Upgrade Scheme
Not every home qualifies and we confirm it before anything is agreed.
The process
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. At the end, we tidy up and run through the work with you. Seeing the property in pictures first means the trip to Little Marlow can be planned properly.
- First we find out about the property, the heating you have now and what you are hoping for.
- 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.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Keep pets and children away from the work area
- Make sure we can reach the consumer unit or fuse board

Air source heat pumps in Little Marlow: the local picture
The 2021 Census found about 36% of households in terraced houses. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door.
If your home is listed, like Cliveden about 2.9 miles south-east, listed building consent comes before any heat pump work. Older homes near Church of St John the Baptist may need extra checks for planning and heat loss before a heat pump is designed.
Little Marlow is about 2 miles north-east of Marlow, in Buckinghamshire. We cover Little Marlow for air source heat pumps, along with the rest of Buckinghamshire. Our area takes in 263 places across Buckinghamshire, large and small. Guildford, roughly 24 miles off, has its own page on this site.

Little Marlow questions
Will a heat pump in Little Marlow need planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Little Marlow is in the Little Marlow Conservation Area. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with Buckinghamshire council, which is normally the planning authority for Little Marlow.
Is the heat pump grant available in Little Marlow?
Yes, if the home and the heat pump meet the scheme’s rules: Little Marlow is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You do not apply yourself: the MCS certified installer does, which is us.
When will I hear back?
On the same working day you contact us. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for problems that can’t wait for a planned visit. Ring 07833 053749 any time and explain the problem.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms, and we help you choose. We install both types.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Why it’s worth doing now in Little Marlow
The 0% VAT rate on heat pumps in homes runs until 31 March 2027, then 5% applies. If you’re thinking about a heat pump, that date is worth knowing, though the right time also depends on your home and heating. Booking before summer means the work in Little Marlow is done before the hot weather.
The pipe route, the height of the units and how we reach them all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
