About our air source heat pumps in City of Westminster
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 will need another way to do that. The work covers radiator systems, hot water cylinders and air-to-water heat pumps, and the jobs we see most are radiators that may be too small for a heat pump and questions about the Boiler Upgrade Scheme.
Terraced houses in a London area like City of Westminster can suit a heat pump well, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

How the visit works
Our engineers 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 anything electrical is made safe before work starts. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. Some blocks in City of Westminster need contractor details in advance, so tell us what your building needs.
- We talk through your home, your current heating and what you want from a heat pump.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- 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.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Getting ready for the visit
- Let us know if the building has a permit or sign-in process
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Unlock any gate, garage or side passage we need
Getting a price
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 City of Westminster
If the emitters can’t give out enough heat, some rooms will not get warm enough. Checking and upsizing them as part of the installation avoids that. Consents in London blocks can take time, which is another reason to plan the job in City of Westminster early.
The cost depends on the system and the number of rooms or units, the access and the parts and time the job needs. You get a fixed price before any work starts, so you know where you stand.

City of Westminster questions
Can I get the Boiler Upgrade Scheme grant in City of Westminster?
City of Westminster 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.
Can I have air conditioning in a flat in City of Westminster?
Usually, 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.
How long does a heat pump installation take?
It takes a few days for most air-to-water installations, with air-to-air systems often quicker. How much of the heating changes decides most of the time and the timing is set out with your quote.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Are my radiators big enough for a heat pump?
It depends on each radiator and the room it heats. Heat pumps run at lower flow temperatures, so radiators give out less heat, and the survey checks each one.

Heat pumps in City of Westminster: local notes
The Valuation Office Agency’s council tax figures put about 46% of homes in and around City of Westminster before 1919, and about 91% of households live in flats, according to the 2021 Census. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. A flat may have no room for a hot water cylinder, and the freeholder normally has a say on the outdoor unit, which can tip the choice towards air-to-air. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Live in one of the older houses around St Mark's? Expect the survey to look closely at heat loss and at the building’s planning status.

When to call us in City of Westminster
Air-to-air systems interest people who want cooling in summer as well as heating. They heat rooms through wall, floor or ceiling units, and can cool them when it’s hot. The grant only applies in some cases, so we check first.
Most people get in touch when they notice one of these:
- No space for a hot water cylinder
- Ageing boilers that will need replacing
- Plans to switch to electric heating with a heat pump
If your home is near Bond Street station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.
Questions to ask before you book
- Whether the company is F-Gas certified, and whether you can check it
- If the figure could change on the day
- Whether extra work needs your approval first
