What happens if it’s left?
A sudden boiler failure rarely leaves room to plan a heat pump properly. Planning ahead gives time for the heat loss survey, the design and the grant application while the old heating still works. In London, hot spells can bring a rush of calls, so planning the work in Mapesbury before summer avoids the wait.
Typical ranges are on our prices page, but your price depends on the job in front of us. Call for a fixed-price quote, and we will explain what it covers.

About our air source heat pumps in Mapesbury
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. Air-to-air systems do not heat hot water, so you’ll need another way to do that. We are often asked to deal with plans to switch to electric heating with a heat pump and a boiler that’s getting old, across air-to-water heat pumps, hot water cylinders and underfloor heating.
In a London area like Mapesbury, many homes are flats or terraces with little outside space, which affects which heat pump suits. An air-to-water system needs space outside and normally 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.

Air source heat pumps in Mapesbury: the local picture
Valuation Office Agency council tax records show about 58% of homes in the Mapesbury area were built in 2000 or later, and about 54% of households live in flats, according to the 2021 Census. Newer homes normally lose less heat, which tends to suit a heat pump well. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Older homes near St Michael the Archangel may need extra checks for planning and heat loss before a heat pump is designed.

Your questions about air source heat pumps in Mapesbury
Does the Boiler Upgrade Scheme cover homes in Mapesbury?
Yes, if the home and the heat pump meet the scheme’s rules: Mapesbury is in England, where it applies. The amount depends on the type of heat pump, and the survey confirms which applies. You do not apply yourself: the MCS certified installer does, which is us.
Can I fit a heat pump in Mapesbury without planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Mapesbury is in a conservation area. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Brent council, usually the authority for Mapesbury.
Are my radiators big enough for a heat pump?
It varies from room to room. We check them all during the survey and the quote shows what’s needed.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will agree what happens next.
How does the warranty work?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition, so keep your service records.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Will I get records for the system?
Yes. You get a written record of every visit, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
When something else is needed
Not every problem is solved by air source heat pumps, and we’d rather say so up front. It doesn’t solve:
- A grant for a home that does not meet the scheme rules
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
- Planning approval where permitted development does not apply
If you’re not sure, just call us on 07833 053749 or email us and we’ll give you a straight answer.

How it works
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. On site, it takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. If a freeholder or agent needs to agree the work in Mapesbury, we can send them the details.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- 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.
- The system is commissioned and registered under MCS, and we show you how to use it.
Getting ready for the visit
- Mention any managing agent or landlord rules we need to follow
- Find the manual or the paperwork for the system, if you have it
- Make sure someone can let us in at the agreed time
Getting a quote
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

When to call us in Mapesbury
Some people want to move away from burning fossil fuels at home. With a heat pump, the heat comes from the air outside and the system runs on electricity, which is why it fits that aim.
Reasons to give us a call include:
- Planning and permitted development questions
- Plans to switch to electric heating with a heat pump
- Choosing between air-to-water and air-to-air
If your home is near Wembley Stadium 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
- What happens if the job turns out to be different on the day
- What the manufacturer’s warranty covers and for how long
- Whether the quote shows VAT clearly
