Headstone: your questions answered
Can I have air conditioning in a flat in Headstone?
Often, yes, but the lease and the freeholder normally have a say. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Is a heat pump in Headstone permitted development?
It comes down to the building and the spot chosen for the outdoor unit. Central Headstone sits inside 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 local planning authority (for Headstone, normally Harrow council).
When will I hear back?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
Am I eligible for a heat pump grant?
Not every home qualifies, so we check. There’s one grant per property, you cannot get one to replace a low-carbon system, and hybrids are excluded, among other rules.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
What VAT do I pay on a heat pump?
Installing an air source heat pump in a home is zero-rated until 31 March 2027, then 5%. It doesn’t apply to businesses, and this is general information rather than tax advice.
How long does a heat pump installation take?
An installation 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. The survey lets us set a firm programme, and you can call 07833 053749 or send an email to book it.
How we handle air source heat pumps in Headstone
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home, so an add-on next to a boiler is not eligible. The work covers homes heated by oil, LPG or gas, air-to-water heat pumps and hot water cylinders, and people most often call us about finding a place for the outdoor unit and questions about the Boiler Upgrade Scheme.
In a London area like Headstone, 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 typically a cylinder, while air-to-air units take less room.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order, and every service is written up.

Signs you need air source heat pumps in Headstone
Homes off the gas grid, heated by oil or LPG, are often good candidates to look at. The Boiler Upgrade Scheme includes an extra £1,500, until March 2027, for air source or ground source heat pumps in homes heated by oil or LPG with no mains gas where the home is eligible.
Look out for these signs:
- Checking emitters for a heat pump
- Checking eligibility for a heat pump grant
- Choosing between air-to-water and air-to-air
Historic houses such as Headstone Manor, about 0.6 miles south-east, are a reminder that listed homes need consent before a heat pump goes in.
Questions to ask before you book

What else we do in Headstone
Air source heat pumps in Headstone: the local picture
About 45% of homes in Headstone and the neighbourhoods around it were built between the wars, according to Valuation Office Agency council tax records. 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.
If your home is near Headstone Lane station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.

Let and managed properties
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
From a single flat to a whole estate, the approach is the same: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
The process
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. The work itself takes a few days on site, depending on the cylinder, the radiators and the pipework involved. A note on parking and access helps us plan a visit to Headstone.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
How to prepare
- Let us know where the consumer unit is
- Tell us about any building rules, permits or sign-in
- Make sure we can reach the outdoor unit, or where it will go
