Before you call an engineer
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.
About our air source heat pumps in Harrow on the Hill
We begin with a room-by-room heat loss survey. That tells us how much heat the home needs, room by room so the system is sized to match. Sizing by rule of thumb is not good enough. The work covers air-to-air heat pumps, radiator systems and air-to-water heat pumps, and the jobs we see most are comparing heat pump types and an oil, LPG or gas boiler near the end of its life.
In a London area like Harrow on the Hill, many homes are flats or terraces with little outside space, and that decides which kind of heat pump works. Air-to-water needs room for the outdoor unit and typically a cylinder, while air-to-air units take less room.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which 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 your building in Harrow on the Hill has a managing agent, a concierge or sign-in rules, mention them when you book.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.

- Then it’s fitted, commissioned and registered with MCS.
Preparing for the visit

Air source heat pumps in Harrow on the Hill: the local picture
About 47% of homes in and around Harrow on the Hill were built between the wars, according to the Valuation Office Agency’s council tax figures. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Northolt Manor, roughly 2.1 miles south-west, is a reminder to check your home’s listing status: permitted development does not cover listed buildings. If you live near Sudbury Hill Harrow station, the survey compares air-to-water and air-to-air for your home before anything is quoted.

From a single flat to a whole estate, the approach is the same: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We are happy to deal with either side and send the records to whoever needs them.
Your questions about air source heat pumps in Harrow on the Hill
Is a heat pump in Harrow on the Hill permitted development?
The answer turns on the property and where the outdoor unit would sit. A conservation area takes in the middle of Harrow on the Hill. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the local planning authority (for Harrow on the Hill, typically Brent council) first.
Does the Boiler Upgrade Scheme cover homes in Harrow on the Hill?
Harrow on the Hill is covered, as the scheme runs across England and Wales. 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.
How long will it take to install a heat pump?
Expect it to take anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for breakdowns that cannot wait. Call 07833 053749 and tell us what’s happened.
What’s the price of a heat pump installation?
Air-to-water installations cost £8,000–£16,000 (0% VAT on homes), before the grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.
Does servicing affect my warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim and we will tell you what your brand asks for.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before work begins, and we tidy up as we go. At the end, we clear up and show you what we’ve done.
When something else is needed
Some problems need a different service or another trade:
- A grant for a home that does not meet the scheme rules
- Insulation work, such as loft or cavity wall insulation
- Disconnecting or servicing a gas boiler
If in doubt, call 07833 053749 or fill in the contact form and we’ll say what we think.
