Air source heat pumps in and around Butt's Green, from the first look to the final check and a fixed price agreed before work begins.

Safe owner checks
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
How we handle air source heat pumps in Butt's Green
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. With air-to-air, hot water has to come from something else. We’re often asked to deal with ageing boilers that will need replacing and checking eligibility for a heat pump grant, across air-to-air heat pumps, homes heated by oil, LPG or gas and hot water cylinders.
Space for an outdoor unit is rarely an issue near Butt's Green, so the design focuses on heat loss and radiators.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

The process
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. If a lane or gateway near Butt's Green is tight for a van, let us know and we’ll plan for it.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
How to prepare
- Make sure we can reach the consumer unit or fuse board
- Dig out any previous service or F-Gas records
- Make sure someone can let us in at the agreed time
Getting a price
The quickest way to a quote is to send pictures: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.

Signs you need air source heat pumps in Butt's Green
Many people look at heat pumps when an oil, LPG or gas boiler is getting old. Planning the change before the boiler fails gives you time to survey, design and apply for any grant, rather than rushing a replacement in winter.
The things we’re asked about most are:
- Wanting to stop using oil, LPG or gas for heating
- Working out where a cylinder could go
- A boiler that is getting old
Every heat pump design starts with a room-by-room heat loss calculation.
What to look for in a quote
- Whether they hold F-Gas company certification, not just individual qualifications
- If the figure could change on the day
- Whether the quote shows VAT clearly

Butt's Green: your questions answered
Will you come out to Butt's Green?
Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you cover Butt's Green for air source heat pumps?
We do: Butt's Green falls inside our working area. Get in touch with the details and we reply the same working day.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water heats radiators or underfloor heating and hot water; air-to-air heats rooms through indoor units and can cool them. With air-to-air, hot water needs another source and the survey helps decide.
Will skipping a service affect the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we’ll tell you what your brand asks for.
Is there VAT on a heat pump?
Homes pay 0% VAT on a heat pump installation until 31 March 2027, then 5%. Hotels and businesses pay the standard rate, and this is not tax advice.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
Rented and managed buildings
Larger air conditioning systems in buildings need more than servicing: 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.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system and we are happy to deal with whoever it is.
