Marlpit Hill: your questions answered
Is a heat pump in Marlpit Hill permitted development?
That depends on the building and where the outdoor unit goes. A conservation area takes in the middle of Marlpit Hill. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where needed, we check with the local planning authority (for Marlpit Hill, usually Sevenoaks council).
Will you come out to Marlpit Hill?
Yes, smaller places are covered as well as towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do I need new radiators for a heat pump?
The heat loss survey answers that, room by room. Where a radiator is already large enough, it stays, and any that need upsizing are set out in the quote.
How do you keep the place clean during the work?
We start with protection: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Will I get records for the system?
Yes. Every visit is written up, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will agree what happens next.
How we handle air source heat pumps in Marlpit Hill
Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. If you are dealing with questions about where the outdoor unit can go and radiators that may be too small for a heat pump, we can help.
Space for an outdoor unit is rarely an issue near Marlpit Hill, so the design comes down to heat loss, radiators and hot water.
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. It also keeps you on the right side of any warranty terms that ask for servicing.

What we are called out for in Marlpit Hill
People also ask about air-to-air heat pumps because they heat and cool. They warm rooms directly through indoor units, and can cool them when it’s hot. The grant only applies in some cases, so we check first.
Look out for any of the following:
- Planning and permitted development questions
- Ageing boilers that will need replacing
- Finding a place for the outdoor unit
If your home is near Edenbridge station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.

Before you call an engineer
Never try to top up, release or handle refrigerant yourself. 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. If you suspect a leak, switch the system off and call us.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
How the visit works
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. On the day, both are in the same hands. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. Photos of the room and the outside of the property help us plan a visit to Marlpit Hill.
- First we find out about the property, the heating you have now and what you’re hoping for.
- 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.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- 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.
How to prepare
- Mention any parking restrictions near the property
- Arrange for someone to be there to let us in
- Give us access to the outside wall, roof or yard where the outdoor unit sits
Ask for a quote
Getting a quote is straightforward. Send a few details and pictures, and we reply the same working day. Where a survey is needed, we arrange a time that suits you.
Advice
How the job changes from property to property
VAT on heat pumps
Heat pumps in homes carry 0% VAT until 31 March 2027, and 5% after that following HMRC’s rules on energy-saving materials. Businesses pay the standard rate.
Air-to-air heat pumps
An air-to-air system heats rooms directly and can also provide cooling. They don’t heat hot water, so that has to come from elsewhere.
A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
