Heat pumps in Pimlico: local notes
VOA council tax data date about 66% of homes across Pimlico and its surrounding area to the post-war years, 1945 to 1972. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Listed buildings are part of the picture here: about 5 within half a mile of the centre, such as Rose Acre House (grade II). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
Live in one of the older houses around Church of the Ascension? Expect the survey to look closely at heat loss and at the building’s planning status. High Elms Manor lies about 2.2 miles south-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

Air source heat pumps in Pimlico
An air-to-water heat pump heats water to a lower temperature than a typical boiler which means some radiators may need upsizing. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. The work covers underfloor heating, air-to-air heat pumps and air-to-water heat pumps, and the jobs we see most are comparing heat pump types and no space for a hot water cylinder.
In a place like Pimlico, some homes are listed, and permitted development doesn’t cover listed buildings, so consent comes first.
Whatever the visit, you get a written record: 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, because it helps with any later warranty question.

Pimlico: your questions answered
Does the Boiler Upgrade Scheme cover homes in Pimlico?
Pimlico is in England, where the Boiler Upgrade Scheme runs. 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. We hold MCS certification, so the application is ours to make for you.
Will you come out to Pimlico?
Yes. Pimlico is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Do you offer emergency call-outs?
Yes. There’s a 24/7 emergency line for breakdowns that can’t wait. Call 07833 053749 and tell us what’s happened.
Do you work on all makes?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Will I need planning consent for an air source heat pump?
That depends on your home and the unit’s position. Flats have tighter limits, conservation areas add conditions, and Article 4 directions can remove rights, so we check during the survey.
The process
If the system has to be off for part of the visit, we tell you before work begins, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Pictures of the space and where the outdoor unit could go let us plan the work in Pimlico.
- We find out about your home and the heating you have now.
- Every room’s heat loss is worked out on site.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- Cost, grant and VAT appear on one fixed-price quote.
- Installation, commissioning and MCS registration complete the job.
Preparing for the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Have the make and model of any existing unit to hand
- Mention any parking restrictions near the property

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
- Planning approval where permitted development does not apply
- Tax advice on your own circumstances
Not sure which it is? You can phone us on 07833 053749 or fill in the contact form and we will tell you honestly.

Different systems, different jobs
Hot water cylinders
The cylinder size depends on how much hot water the household uses.
Air-to-water heat pumps
Air-to-water systems take heat from the air and put it into your central heating and hot water. It takes over from the boiler and we install it to MCS standards.
Owner checks or an engineer?
Good habits make our visits easier, not unnecessary. 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.
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
What a customer said
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
