Air source heat pumps for homes and businesses in Mersham
A heat pump takes heat from the outside air and moves it into your home with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way, and air-to-air heat pumps are sometimes simply called air conditioning. If you are dealing with checking whether planning permission is needed and plans to switch to electric heating with a heat pump, we can help.
In a place like Mersham, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so we check consent first.
Warranty periods vary by brand and by product. Daikin, for instance, 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.

Why deal with it now?
Radiators that are too small for a heat pump’s lower flow temperature leave rooms cool. The survey picks this up before installation. For a village like Mersham, booking ahead lets us plan the trip properly.
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you’re unsure, give us a ring on 07833 053749 or email us for straight advice and a fixed price.

Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Avoid switching the heat pump on and off often
- Leave indoor units unobstructed
- Keep the MCS certificate with the manufacturer’s paperwork
Handover includes the controls and how to get the best from a heat pump. Steady running suits a heat pump better than switching on and off, and we’ll explain the settings for your home.
Heat pumps prefer steady, low-temperature running, using the settings agreed at handover.

Pricing air source heat pumps in Mersham
Some jobs are bigger than they look, and some smaller. The main factors:
- A single visit or a regular plan
- The equipment or parts the job needs
- Access, including height, roofs and ladders
Homes, offices, shops and public buildings are all priced the same way: the equipment, the access, the work involved and the time it takes. Call for a fixed-price quote and we’ll explain each part.
Helping us quote
When you call or email, these details help:
- The outside wall, roof or yard where the outdoor unit sits or would go
- A short video of any fault, such as a noise or a flashing light
- Your consumer unit or fuse board
Our prices page gives typical ranges, but your quote is based on your job, because every property is different. Once we’ve looked at the job, from pictures or on a survey, you get a fixed price. To start, phone us on 07833 053749 or fill in the contact form.
The process
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes a few days for most air-to-water installations, with air-to-air systems often quicker. Seeing the property in photos first means the trip to Mersham can be planned properly.
- 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.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Commissioning, MCS certification and a handover of the controls finish the job.
Getting ready for the visit
- Make sure we can reach the consumer unit or fuse board
- Mention any parking restrictions near the property
- Keep pets and children away from the work area
Ask for a quote
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Mersham: your questions answered
Is Mersham within the area you cover?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I fit a heat pump in Mersham without planning permission?
It depends on the property. Central Mersham sits inside a conservation area. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with Ashford council, which is typically the planning authority for Mersham first.
Does servicing affect my warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.
How much time does a heat pump install need?
An installation 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. The survey lets us set a firm programme, so ring 07833 053749 or fill in the contact form to arrange one.
What accreditations do you have?
We are an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re members of Checkatrade too.
Is there VAT on a heat pump?
Installing an air source heat pump in a home is zero-rated until 31 March 2027, then 5%. Businesses pay the standard rate, and this is general information rather than tax advice.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before you book anyone, and we’re happy to show ours.
Air source heat pumps around Mersham
Valuation Office Agency council tax records show about 45% of homes in and around Mersham were built in 2000 or later, and Census 2021 figures found about 79% of households in detached or semi-detached houses. Better insulated, newer homes are often a good match for a heat pump. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
