Air source heat pumps in Jersey Farm
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. Air-to-air systems do not heat hot water, so you’ll need another way to do that. If the problem is questions about listed buildings or conservation areas and an oil, LPG or gas boiler near the end of its life, we can help.
Homes around Jersey Farm normally have space for an outdoor unit and a hot water cylinder, so heat loss, radiators and the electrics are what we check.
Each manufacturer sets its own warranty period. 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.

Jersey Farm: your questions answered
Is the heat pump grant available in Jersey Farm?
Jersey Farm is covered, as the scheme runs across England and Wales. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. You don’t apply yourself: the MCS certified installer does, which is us.
Do you cover Jersey Farm for air source heat pumps?
Yes. Jersey Farm is one of the places we cover. Just call 07833 053749 or send an email with a few details.
What’s the difference between air-to-water and air-to-air heat pumps?
The right choice depends on the property and what you need. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions, and we set out the options after the survey.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
What’s the price of a heat pump installation?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
Will I need planning consent for an air source heat pump?
It depends on the property and where the unit goes. Flats have tighter limits, conservation areas add conditions, and Article 4 directions can remove rights and we look at it during the survey.
Can I do the refrigerant work myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
System by system
Hot water cylinders
Hot water from an air-to-water system is stored in a cylinder. Space for the cylinder is part of the survey particularly in homes with a combi boiler.
Air-to-air heat pumps
Since 2025, air-to-air heat pumps can also be permitted development in England, subject to the conditions. A unit used solely for cooling isn’t covered and need a check with the council.
What a heat pump looks like in Jersey Farm
VOA council tax data date about 40% of homes across Jersey Farm and its surrounding area to the post-war years, 1945 to 1972. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. At about 21 miles from central London, Jersey Farm sits inside the area we cover across London and the South East.
If your home is one of the older properties near Saint Mary's, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

What else we do in Jersey Farm
Safe owner checks
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and call us on 07833 053749 or write to us at info@aircondoctor.co.uk.
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 refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
What we are called out for in Jersey Farm
Many enquiries start with a question about the Boiler Upgrade Scheme. Whether you can get the grant depends on your home and the scheme conditions, so we check before you commit.
Keep an eye out for these signs:
- Planning and permitted development questions
- Comparing heat pump types
- An oil, LPG or gas boiler near the end of its life
Childwickbury Manor lies about 2.3 miles west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
Questions to ask before booking
- How VAT is shown, and which rate applies
- Whether a new circuit is included and who certifies it
- Whether you get F-Gas records where refrigerant is involved
What we do, step by step
On the day, we arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Tell us about any gates or steps at your property near Jersey Farm when you book.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- 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.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
Before we arrive
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure we can reach the consumer unit or fuse board
- Mention any parking restrictions near the property
How to get a quote
Photos are the fastest route to a quote: 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 many jobs can be priced from that.
