How we handle air source heat pumps in Watersfield
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. The work covers hot water cylinders, air-to-air heat pumps and underfloor heating, and people most often call us about no space for a hot water cylinder and finding a place for the outdoor unit.
Homes around Watersfield usually have room outside for a heat pump, 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. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

System by system
Heat loss surveys
Without a proper survey, a heat pump can be too big or too small and that matters for comfort and running.
Hot water cylinders
An older cylinder may not suit a heat pump and we tell you if it needs replacing.
What owners can safely do
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
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 us on 07833 053749.
How it works
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes a few days for most air-to-water installations, with air-to-air systems often quicker. Photos of the existing unit help with repairs and servicing in Watersfield.
- 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.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Getting ready for the visit
- Dig out any previous service or F-Gas records
- Make sure we can reach the consumer unit or fuse board
- Mention any roof access, ladders or high-level work
Getting a quote
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
Advice
Questions from Watersfield
Will you come out to Watersfield?
Yes. Watersfield is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Is planning permission needed for a heat pump in Watersfield?
It depends on the property. Central Watersfield sits inside the Watersfield 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 the local planning authority (for Watersfield, usually Chichester council).
Can you look at a system you didn’t fit?
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.
Can you set up regular servicing?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
How much does an air source heat pump cost?
Expect £8,000–£16,000 for an air-to-water system, with 0% VAT on homes, before the grant is taken off. The heat pump size, radiator changes and the cylinder decide where in that range you are. Air-to-air is priced after a survey.
Are my radiators big enough for a heat pump?
The heat loss survey answers that, room by room. Where a radiator is already large enough, it stays and any changes are in the quote.
Can I get the Boiler Upgrade Scheme grant?
It depends on your home and the system. The scheme gives £7,500 for eligible air-to-water or ground source systems, and £2,500 for air-to-air only under strict conditions. We check before you commit.
