Air source heat pumps around Old Chiswick
Valuation Office Agency council tax records put about 55% of homes in and around Old Chiswick before 1919, and the last census (2021) found about 51% of households live in flats. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. For flats, the first questions are where an outdoor unit could go, whether a cylinder fits and what the lease allows. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Period properties close to St. Nicholas Church can suit a heat pump, though insulation and any heritage protection are checked first. With Hogarth's House about 0.4 miles west, it’s worth asking whether your own home is listed before planning a heat pump.

About our air source heat pumps in Old Chiswick
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day so the system is sized to match. Sizing by rule of thumb isn’t good enough. The work covers underfloor heating, radiator systems and hot water cylinders, and common reasons people get in touch are plans to switch to electric heating with a heat pump and deciding which kind of heat pump suits the home.
Terraced houses in a London area like Old Chiswick can suit a heat pump well, as long as there’s a sensible spot for the outdoor unit and its noise is checked against the MCS planning standard.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

The process
Our engineers arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Old Chiswick.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Before we arrive
- Mention any roof access, ladders or high-level work
- Tell us about parking and loading
- Find the manual or the paperwork for the system, if you have it
How to get a quote
Quotes don’t take long. Send a few details and pictures, and we reply the same working day. Where a survey is needed, we arrange a time that suits you.

For eligible off-gas homes on oil or LPG, an extra £1,500 is on offer until March 2027. If that applies to you, it’s worth asking about sooner rather than later. Approvals for flats in Old Chiswick can take longer than the install itself.
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Call for a fixed-price quote and we’ll explain each part.

Your questions about air source heat pumps in Old Chiswick
Can I fit a heat pump in Old Chiswick without planning permission?
That depends on the building and where the outdoor unit goes. The Old Chiswick Conservation Area takes in the middle of Old Chiswick. 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 don’t 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 Old Chiswick, usually Hounslow council).
Can you fit air conditioning in a London flat in Old Chiswick?
Normally, yes, though leaseholders normally need the freeholder’s agreement. 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.
Can I do any of the installation 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.
Why does F-Gas certification matter?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
Can I get the Boiler Upgrade Scheme grant?
Quite possibly. In England and Wales it pays £7,500 for an eligible air-to-water or ground source heat pump, and £2,500 for air-to-air under tighter rules. Homes heated by oil or LPG with no mains gas can get an extra £1,500 towards an air source or ground source heat pump until March 2027. The survey is where we check your home against them.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before we start, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
Looking after your system
So the system stays in good health:
- Clear leaves and debris from the outdoor unit
- Keep radiators clear
- Book a yearly service
Now and then in cold weather, the outdoor unit defrosts itself. You might see steam or hear the unit change note and it’s part of how the system works.
Do not cover radiators with furniture or heavy curtains, as the system relies on them giving out heat.
What you can do yourself, and what needs us
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone 07833 053749.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
