Air source heat pumps in Hayes
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. With air-to-air, hot water has to come from something else. The work covers air-to-air heat pumps, air-to-water heat pumps and homes heated by oil, LPG or gas, and people most often call us about checking eligibility for a heat pump grant and plans to switch to electric heating with a heat pump.
In a London area like Hayes, many homes are flats or terraces with little outside space, and that decides which kind of heat pump works. An air-to-water system needs space outside and typically a hot water cylinder inside, while air-to-air units take less room.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork so it’s to hand next time.

What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. The visit takes from a couple of days to around a week, depending on the system and how much of the heating changes. A few photos of the room, the outside wall and the fuse board help us plan a job in Hayes.
- It starts with a conversation about the home, the existing heating and your plans.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Getting ready for the visit
- Have the make and model of any existing unit to hand
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know if the units are on a roof, a high wall or in a locked area
Getting a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price before any work starts.

Why act early in Hayes
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water works with radiators and a cylinder, with a £7,500 grant for eligible homes, while air-to-air heats and cools rooms and has a £2,500 grant only in limited cases. We explain which makes sense for you. In London, hot spells can bring a rush of calls, so planning the work in Hayes before summer avoids the wait.
Our prices page shows typical ranges, but your price depends on the job in front of us. Call for a fixed-price quote, and we’ll talk you through it.

Questions from Hayes
Can I get the Boiler Upgrade Scheme grant in Hayes?
Yes, if the home and the heat pump meet the scheme’s rules: Hayes is in England, where it applies. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. As an MCS certified installer, we apply for it on your behalf.
Can you fit air conditioning in a London flat in Hayes?
Typically, yes, though leaseholders normally need the freeholder’s agreement. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
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.
Is Hayes in your area?
Yes. We cover Hayes and across Greater London, as part of our area across London and the South East. For a fixed-price quote, ring us on 07833 053749.
Do you provide F-Gas records?
Yes. You get a written record of each visit, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Are you F-Gas certified?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Do you survey before quoting?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.
What you can do yourself, and what needs us
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and ring us on 07833 053749 or use the quote form.
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Heat pumps in Hayes: local notes
About 50% of homes in the Hayes area were built between the wars, according to VOA council tax data. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Live in one of the older houses around Church of St Mary? Expect the survey to look closely at heat loss and at the building’s planning status. Historic houses such as Northolt Manor, about 3 miles north-east, are a reminder that listed homes need consent before a heat pump goes in.
