How we handle air source heat pumps in Osterley
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. If the problem is finding a place for the outdoor unit and choosing between air-to-water and air-to-air, we can sort it out.
For flats in Osterley, the lease, the freeholder and the rules for flats all come into it. Permitted development limits are different for flats, so we check the position before we design.
The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler, so keep it safe.

What you can do yourself, and what needs us
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and phone us on 07833 053749 or send an email.

Common problems we fix in Osterley
For homes with no mains gas, heated by oil or LPG, a heat pump is well worth considering. 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.
If any of these sounds familiar, it’s worth a diagnosis:
- Questions about where the outdoor unit can go
- Questions about the Boiler Upgrade Scheme
- Wanting to stop using oil, LPG or gas for heating

Comparing quotes
- Exactly what the price includes, from supply and fitting to commissioning
- Why the equipment they’re quoting suits the job
- Whether the quote is a fixed price
The process
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, do the work, test what we’ve done and explain it all to you. The visit itself takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Before a visit in Osterley, we ask where the van can stop and how we reach the outdoor unit.
- First, a chat about the property and your goals for the heating.
- 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.
- Installation follows on the agreed dates.
- We commission it, complete the MCS certificate and show you how to use it.
How to prepare
- Tell us about parking and loading
- Make sure someone can let us in at the agreed time
- Move furniture away from the wall where we’ll be working

Advice
What air conditioning won’t do
Before you book, it helps to know what’s not included:
- Insulation work, such as loft or cavity wall insulation
- A grant for a home that doesn’t meet the scheme rules
- Getting planning permission or listed building consent on your behalf

Osterley: your questions answered
Can I fit a heat pump in Osterley without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Central Osterley sits inside the Osterley Park Conservation Area. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where needed, we check with Hounslow council, which is typically the planning authority for Osterley.
Do I need permission to put air conditioning in my flat in Osterley?
Normally, yes, though leaseholders normally need the freeholder’s agreement. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for problems that can’t wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Osterley and across Greater London. Let us know who the records should go to.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
Air source heat pumps around Osterley
VOA council tax data show about 53% of homes in the Osterley area date from 1919 to 1939. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. For a London home, the outdoor unit position and the MCS noise check need careful planning.
If you live near Isleworth station, the survey compares air-to-water and air-to-air for your home before anything is quoted.
