What the work involves, system by system
Hot water cylinders
Hot water from an air-to-water system is stored in a cylinder. The survey looks at where it can go, especially if you have a combi boiler.
Air-to-air heat pumps
An air-to-air system heats rooms directly and can also provide cooling. They do not heat hot water, so that has to come from elsewhere.
About our air source heat pumps in Greenhill
Air source heat pumps collect heat from outdoor air and bring it inside, using electricity to drive the process. It works on the same principle as air conditioning, run the other way, and air-to-air heat pumps are sometimes simply called air conditioning. The work covers homes heated by oil, LPG or gas, radiator systems and air-to-water heat pumps, and common reasons people get in touch are a boiler that’s getting old and choosing between air-to-water and air-to-air.
Homes in Greenhill are often flats and terraces, where outside space is limited, and that decides which kind of heat pump works. Air-to-water needs room for the outdoor unit and typically a cylinder, while air-to-air units take less room.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

What else we do in Greenhill
Questions from Greenhill
Is the heat pump grant available in Greenhill?
Greenhill is covered, as the scheme runs across England and Wales. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. As an MCS certified installer, we apply for it on your behalf.
Can you fit air conditioning in a London flat in Greenhill?
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.
Do you survey before quoting?
Yes. Every job is looked at first, either on a site survey or from pictures and details for simple jobs. A fixed-price quote follows.
Does servicing affect my warranty?
For some brands, yes. Send us the make and model and we will tell you what the manufacturer expects, and book the service at the interval they recommend.
How do you keep the place clean during the work?
Protection goes down first: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
How does the warranty work?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
Is Greenhill in your area?
Yes. We work across Greater London, Surrey, Kent, East and West Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Greenhill.
After we have gone
Here’s the after-treatment advice, short and simple:
- Store the MCS certificate and warranty documents together
- Book a yearly service
- Keep radiators clear
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Heat pumps prefer steady, low-temperature running as explained at handover.
How it works
If the system has to be off for part of the visit, we tell you before we start so it doesn’t catch you out. In a business, work can often be done one area at a time. The work 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. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Greenhill.
- First we find out about the property, the heating you have now and what you are hoping for.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- You get a fixed-price quote, with any grant you’re 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.
Getting ready for the visit
- Mention any parking restrictions near the property
- Clear access to the fuse board
- Find the manual or the paperwork for the system, if you have it
Getting a quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.

Homes in Greenhill and heat pumps
The Valuation Office Agency’s council tax figures put about 65% of homes in Greenhill and the neighbourhoods around it before 1919, and about 80% of households live in flats, according to the 2021 Census. Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. In flats, space for an outdoor unit and a cylinder can be limited, and the lease and freeholder come into it, so air-to-air is sometimes the better fit. For a London home, the outdoor unit position and the MCS noise check need careful planning.
If your home is near Hampstead Heath station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.

What we’re called out for in Greenhill
Some homes heated by electric heaters or storage heaters consider a heat pump instead. A survey shows whether a heat pump suits the property and what would need to change, and we explain the grant position for your home.
Reasons to give us a call include:
- Finding a place for the outdoor unit
- Planning and permitted development questions
- Plans to switch to electric heating with a heat pump
If your home is one of the older properties near Rosslyn Hill Unitarian Chapel, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
