Different systems, different jobs
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 that has to come from elsewhere.
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 is MCS certified when we install it.
Air source heat pumps in Waltham St Lawrence, done properly
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 the installer makes the application. Eligibility depends on the property, so we confirm it before anything is agreed. Typical jobs include planning and permitted development questions and deciding on the outdoor unit position, on air-to-water heat pumps, air-to-air heat pumps and homes heated by oil, LPG or gas.
Space for an outdoor unit is rarely an issue near Waltham St Lawrence, so the design comes down to heat loss, radiators and hot water.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual so it’s to hand next time.

What happens on the day
We keep the work area tidy as we go, 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 from a couple of days to around a week, depending on the system and how much of the heating changes. Seeing the property in pictures first means the trip to Waltham St Lawrence can be planned properly.
- We start with your plans and the property.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- Installation follows on the agreed dates.
- We commission it, complete the MCS certificate and show you how to use it.
How to prepare
- Keep pets and children away from the work area
- Let us know if the building has a permit or sign-in process
- Clear the space around the indoor unit, or where it will go
How to get a quote
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from photos and measurements. Then you get a fixed price so you know the cost before we begin.
Advice
Before you call an engineer
Owner care supports servicing; it does not replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
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 07833 053749 or write to us at info@aircondoctor.co.uk.
Keeping the system healthy
So the system stays in good health:
- Clear leaves and debris from the outdoor unit
- Leave indoor units unobstructed
- Seal draughts where you can
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork for future reference.
Let the heat pump run steadily rather than switching it on and off, using the settings agreed at handover.
Questions from Waltham St Lawrence
Is the heat pump grant available in Waltham St Lawrence?
Waltham St Lawrence is in England, where the Boiler Upgrade Scheme runs. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. As an MCS certified installer, we apply for it on your behalf.
Is planning permission needed for a heat pump in Waltham St Lawrence?
There’s no single answer: the building and the outdoor unit position decide it. Central Waltham St Lawrence sits inside a conservation area. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where needed, we check with Windsor and Maidenhead council, which is normally the planning authority for Waltham St Lawrence.
Do you cover Waltham St Lawrence?
Yes. Our engineers work in Waltham St Lawrence, as part of our area across London and the South East. We’re based in East Grinstead, West Sussex.
How long does a heat pump installation take?
A typical installation takes from a couple of days to around a week, depending on the system and how much of the heating changes. The programme is planned to keep time without heating short, and we explain it in advance.
How does the warranty work?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition so it’s worth keeping the service records.
Will my radiators work with 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 you come out in an emergency?
Yes. Our emergency line runs 24/7 for breakdowns that cannot wait. Ring 07833 053749 any time and explain the problem.
