About our air source heat pumps in Marden's Hill
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. Air-to-air systems do not heat hot water, so you’ll need another way to do that. The work covers underfloor heating, air-to-water heat pumps and radiator systems, and common reasons people get in touch are planning and permitted development questions and deciding on the outdoor unit position.
Space for an outdoor unit is rarely an issue near Marden's Hill, so the design focuses on heat loss and radiators.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

How the visit works
Think of the visit in three stages: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes from a couple of days to around a week, depending on the system and how much of the heating changes. A few photos help us make the most of a visit to Marden's Hill.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- 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
- Mention any managing agent or landlord rules we need to follow
- Plan for pets to be kept clear during the visit
- Mention any roof access, ladders or high-level work

- Questions about the Boiler Upgrade Scheme

Air source heat pumps around Marden's Hill
About 77% of households live in detached or semi-detached houses, according to Census 2021 figures. Houses normally have space for an outdoor unit and a hot water cylinder. Forest Lodge Cottage, listed at grade II, is one of roughly 3 protected buildings and structures in the half-mile around Marden's Hill’s centre. Where a home is affected, the outdoor unit position is settled with the local planning authority (normally Wealden council) before the heat pump design is finished.
Groombridge Place lies about 3.8 miles north-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

FAQs for Marden's Hill
Does the Boiler Upgrade Scheme cover homes in Marden's Hill?
Marden's Hill is covered, as the scheme runs across England and Wales. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. You do not apply yourself: the MCS certified installer does, which is us.
Will you come out to Marden's Hill?
Yes. Marden's Hill is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is a heat pump permitted development?
It depends on the property and where the unit goes. Flats have different limits, conservation areas have extra conditions, and an Article 4 direction can remove the rights, so we check during the survey.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Do you provide F-Gas records?
Yes. You get a written record of every visit, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
Do you work on systems someone else installed?
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.
Before you call an engineer
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. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and call 07833 053749 or fill in the contact form.
What a customer said
“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.”
