Air source heat pumps for homes and businesses in West Barnes
A £2,500 grant is available for some air-to-air heat pumps, with conditions. 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; adding it alongside a boiler does not qualify. If the problem is an oil, LPG or gas boiler near the end of its life and deciding which kind of heat pump suits the home, we can sort it out.
In a flat in West Barnes, the lease and the freeholder normally decide where a heat pump can go. The planning rules for flats are stricter than for houses, so we check the position before we design.
Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

What happens on the day
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs attention later is pointed out. The visit takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. A few pictures of the room, the outside wall and the fuse board help us plan a job in West Barnes.
- You tell us about the home and what you want from a heat pump.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- We recommend air-to-water or air-to-air and check the grant position.
- Installation follows on the agreed dates.
- We commission it, complete the MCS certificate and show you how to use it.
How to prepare

Fixed-price quotes for air source heat pumps in West Barnes
Before we fix a price, we need to know a few things. We check:
- The brand, model and parts involved
- The electrical supply and whether a new circuit is needed
- One-off work versus a regular service cycle
Putting several jobs into one visit often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed price.
Before you get in touch
Simple jobs can often be priced from pictures and some basics. Send what you can of the following:
- Wide pictures of the room or the existing unit
- A close-up of the unit’s label showing the model number
- The outside wall, roof or yard where the outdoor unit sits or would go
Every quote shows the VAT clearly, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, give us a ring on 07833 053749, or email if that’s easier.
For landlords and property managers
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.
Records are where property maintenance often slips. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
West Barnes questions
Can you do air source heat pumps in West Barnes?
Yes. West Barnes is one of the places we cover. Just ring 07833 053749 or drop us a line with a few details.
Can you fit air conditioning in a London flat in West Barnes?
In many cases, yes, once the lease and the building’s rules are checked. 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.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Will skipping a service affect the warranty?
For some brands, yes. Send us the make and model and we will tell you what the manufacturer expects and stick to the interval they set.
Who is responsible for leak checks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us in West Barnes and across Greater London. Tell us who should receive the paperwork.
How much time does a heat pump install need?
An installation takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. We confirm the timing after the survey, so call us on 07833 053749 or drop us a line to arrange one.
Heat pumps in West Barnes: local notes
About 46% of homes in and around West Barnes were built between the wars, according to VOA council tax data. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Historic houses such as Southside House, about 1.1 miles north, are a reminder that listed homes need consent before a heat pump goes in. Homeowners near Motspur Park station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.
