How the job changes from property to property
Air-to-water heat pumps
An air-to-water heat pump heats water for your radiators or underfloor heating and your hot water cylinder. It replaces the boiler as the main heat source and we install it to MCS standards.
Air-to-air heat pumps
An air-to-air system heats rooms directly and can also provide cooling. Hot water needs a separate source so you’ll need another way to heat it.
How we handle air source heat pumps in Holtsmere End
Air-to-water heat pumps heat your hot water through 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. Common call-outs are for checking eligibility for a heat pump grant and working out whether radiators need upsizing, across homes heated by oil, LPG or gas, air-to-air heat pumps and air-to-water heat pumps.
For a home around Holtsmere End that is off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
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, ready for the next service or a warranty query.

Your questions about air source heat pumps in Holtsmere End
Will you come out to Holtsmere End?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Can I get the Boiler Upgrade Scheme grant in Holtsmere End?
Holtsmere End is in England, where the Boiler Upgrade Scheme runs. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. The installer applies, and we’re MCS certified.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
Are my radiators big enough for a heat pump?
The heat loss survey answers that, room by room. Rooms where the radiator is big enough stay as they are and any changes are in the quote.
Is the equipment covered by a warranty?
It’s the manufacturer’s warranty, which varies by brand. For example, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
Do you have a 24/7 line?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll advise on what to do next.
How do you keep the place clean during the work?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Landlords, agents and facilities managers
Portfolio owners often want one contractor and one number. We work across London and the South East, so a run of properties can go into one programme and kept to a regular schedule.
Keeping records across a portfolio is half the battle. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
How the visit works
If the system has to be off for part of the visit, we tell you before work begins so it does not catch you out. In a business, work can often be done one area at a time. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. Seeing the property in photos first means the trip to Holtsmere End can be planned properly.
- First we find out about the property, the heating you have now and what you’re hoping for.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- 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.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Keep pets out of the rooms we are working in
- Tell us about any building rules, permits or sign-in
- Arrange for someone to be there to let us in
Getting a quote
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. To get one, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk.

What a heat pump looks like in Holtsmere End
Historic England lists about 4 buildings and structures within half a mile of the centre of Holtsmere End, including Holtsmere Manor (grade II). For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with St Albans City council, normally the planning authority here where needed. Holtsmere End is about 25 miles from central London, well within the area we cover from our base in East Grinstead.
Childwickbury Manor, roughly 3.8 miles east, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.
