Cooler summers, warmer winters, expertly fitted across London.

It depends on the number of rooms, the size and type of indoor units, the distance between indoor and outdoor units, access, and any making-good or electrical work. A single wall-mounted split is the simplest job; multi-room and commercial systems vary much more. We provide a written quotation after understanding your property, so you know exactly what is included.

Often you need some form of consent. Leaseholders usually need their freeholder or managing agent’s approval for external units, and planning permission or listed building consent may be required for visible units, conservation areas or listed buildings. Requirements vary between boroughs and buildings, so we discuss this at the start and help you put the right information together.

Yes. Most modern split and multi-split systems are reverse-cycle heat pumps, so the same indoor unit provides efficient heating in winter and cooling in summer. Many London customers use them to supplement central heating in bedrooms, home offices, loft conversions and conservatories that are hard to keep comfortable.

A straightforward single split system is often completed within a day. Multi-room systems, longer pipe runs, ceiling cassettes, ducted units and commercial installations take longer and may be phased around your business or household. We confirm the expected programme in your quotation so you can plan around it.

Most manufacturers recommend at least an annual service for domestic systems, while busy commercial systems often benefit from more frequent visits. Regular servicing keeps filters and coils clean, helps the system run efficiently and can pick up issues before they become breakdowns. Check your manufacturer’s warranty terms too, as servicing is often a condition.

We cover homes and businesses across Greater London, including Central, North, East, South and West London. Our areas pages explain what to consider in each borough and neighbourhood, from mansion blocks in Kensington to high-rise apartments in Canary Wharf and family homes in the suburbs.

Running costs depend on the unit’s efficiency, how well it is sized, how warm the room gets and how many hours it runs. Modern inverter systems slow down rather than switching off and on, which helps them use energy efficiently once a room is comfortable. Compare SEER (cooling) and SCOP (heating) ratings between models, and keep filters clean so the unit does not have to work harder.

Not necessarily. Single split systems pair one indoor unit with one outdoor unit, which is simple and resilient. A multi-split connects several indoor units to one larger outdoor unit, saving wall or balcony space. This is useful in flats where consent is limited to one condenser position. Which is better depends on the rooms, their use and the available space outside.
