About our air source heat pumps in Watton at Stone
For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. If the problem is a boiler that’s getting old and choosing between air-to-water and air-to-air, we can sort it out.
Older and listed homes in villages like Watton at Stone need extra care, and permitted development does not cover listed buildings, so consent comes first.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Watton at Stone: your questions answered
Is a heat pump in Watton at Stone permitted development?
The answer turns on the property and where the outdoor unit would sit. There’s a conservation area, the Watton at Stone Conservation Area, close to central Watton at Stone. 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 planning department at East Hertfordshire council, usually the authority for Watton at Stone.
Is the heat pump grant available in Watton at Stone?
Yes, the scheme covers homes in England, including Watton at Stone, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
Do you survey before quoting?
Yes. Every job is looked at first, on a survey, or from your pictures and details where the job is simple. A fixed-price quote follows.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Is Watton at Stone in your area?
Yes. Our engineers work in Watton at Stone, within the South East and London area we cover. Our base is in East Grinstead, West Sussex.
Why does F-Gas certification matter?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That isn’t optional: it’s required by law, and we hold it.
How soon will you get back to me?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
How the visit works
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes a few days for most air-to-water installations, with air-to-air systems often quicker, and we tidy up before we leave. Somewhere like Watton at Stone, it helps to know about lanes, gates and where to park.
- 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.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
How to prepare
- Mention any managing agent or landlord rules we need to follow
- Keep pets and children away from the work area
- Clear the space around the indoor unit, or where it will go
