About our air source heat pumps in Little Stanmore
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. If the problem is questions about the Boiler Upgrade Scheme and working out whether radiators need upsizing, we can sort it out.
In a London area like Little Stanmore, many homes are flats or terraces with little outside space, which affects which heat pump suits. Air-to-water needs room for the outdoor unit and usually a cylinder, while air-to-air units take less room.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

Air source heat pumps in Little Stanmore: the local picture
About 66% of homes in and around Little Stanmore were built between the wars, according to VOA council tax data. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. In London, outside space and the rules for flats often decide which kind of heat pump suits.
With Headstone Manor about 3.1 miles west, it’s worth asking whether your own home is listed before planning a heat pump.

After we’ve gone
Here’s the after-treatment advice, in brief:
- Check what your manufacturer’s warranty asks of you
- Use the settings explained at handover
- Look at insulation alongside the heat pump
We show you how to use the controls and explain how a heat pump works differently from a boiler. Heat pumps tend to work best running steadily rather than in short bursts so we set the controls up with you.
Leave space around the outdoor unit. Airflow is what it runs on so keep it unobstructed.
Common questions in Little Stanmore
Can I get the Boiler Upgrade Scheme grant in Little Stanmore?
Little Stanmore 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.
Is planning permission needed for a heat pump in Little Stanmore?
The answer turns on the property and where the outdoor unit would sit. The centre of Little Stanmore is in a conservation area. 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 Harrow council, which is usually the planning authority for Little Stanmore first.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition, so keep your service records.
Do you offer emergency call-outs?
Yes. There’s a 24/7 emergency line for breakdowns that cannot wait. Ring 07833 053749 any time and explain the problem.
Are my radiators big enough for a heat pump?
The heat loss survey answers that, room by room. Where a radiator is already large enough, it stays, and any that need upsizing are set out in the quote.
How long will it take to install a heat pump?
The work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. The survey lets us set a firm programme, and you can phone us on 07833 053749 to book it.
Different systems, different jobs
Outdoor unit position and planning
Flats and blocks of flats have different limits, and Article 4 directions can remove rights. Listed buildings also need separate consent and we check what applies to you.
Radiators and underfloor heating
At lower water temperatures, radiators give out less heat, and the survey checks each one.
What we do, step by step
The first job on site is protection: sheets over the floor and any furniture nearby and nothing is moved without asking you. After that, anything electrical is made safe and we start. The work on site takes from a couple of days to around a week, depending on the system and how much of the heating changes, and we clear up before we go. For a job in Little Stanmore, tell us about parking, permits and access to the building when you get in touch.
- We start with your plans and the property.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- The system is installed and connected to the controls.
- We commission it, complete the MCS certificate and show you how to use it.
Before we arrive
- Mention any roof access, ladders or high-level work
- Tell us about parking and loading
- Move furniture away from the wall where we will be working
