Multi-split air conditioning in March
Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for. In a house in March with a usable loft, multi-split pipes can often run through it so the front stays clear.
Multi-split is a good fit for March flats and maisonettes where only a balcony or one rear wall is available. March sits around 14 miles from Peterborough, inside our Cambridgeshire area. Postcode districts we cover here include PE15.
Prices in March
For March, expect roughly £2,745 to £8,695 for 2–4 rooms, VAT included, adjusted for typical East of England rates. That is above the UK middle, mainly because labour and access cost more in the East of England. What moves a quote in March up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our East of England figures, the Triple option (three rooms with mixed indoor styles and Wi-Fi control throughout) is about £3,745–£6,095.
Twin
Two rooms on one outdoor unit, wall-mounted indoor units, standard routes.
Triple
Three rooms with mixed indoor styles and Wi-Fi control throughout.
Quad
Four or five rooms, longer concealed runs or a ducted unit in a loft void.
Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
A survey in March usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
What is included
Every job in March includes:
- One outdoor unit sized to the combined load
- Pressure test, vacuum and refrigerant charge calculated for the pipe lengths
- Planned pipe routes through lofts, floors or trunking
- An indoor unit and controls for every room
- Free survey with a room-by-room heat-gain check
