How we handle air source heat pumps in Wonersh
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales and the installer makes the application. Eligibility depends on the property, so we confirm it before anything is agreed. Common call-outs are for moving away from fossil-fuel heating and questions about the Boiler Upgrade Scheme, on hot water cylinders, air-to-air heat pumps and homes heated by oil, LPG or gas.
Older and listed homes in villages like Wonersh need extra care, and permitted development does not cover listed buildings, so consent comes first.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

What the work involves, system by system
VAT on heat pumps
HMRC says most air conditioning units are air source heat pumps, but each case depends on the facts and the VAT is confirmed on your quote.
Hot water cylinders
Existing cylinders may not be suitable for a heat pump and we tell you if it needs replacing.

Wonersh questions
Will a heat pump in Wonersh need planning permission?
The answer turns on the property and where the outdoor unit would sit. Central Wonersh is a short walk from the Wonersh 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 the local planning authority (for Wonersh, normally Waverley council) first.
Will you come out to Wonersh?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Will I get records for the system?
Yes. You get a written record of each visit, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
Can you come out in an emergency?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we’ll advise on what to do next.
Do I need to service the system to keep the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
How the visit works
We book the visit for a day and time that suit you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, the work 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 Wonersh.
- First we find out about the property, the heating you have now and what you’re hoping for.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Before we arrive
- Let us know if the building has a permit or sign-in process
- Mention any roof access, ladders or high-level work
- Clear access to the fuse board
Ask for a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price so you know the cost before we begin.
Advice
Owner checks or an engineer?
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
