Why two quotes for the same room can differ
- Output: a 5 kW unit for a sunny living room costs more than a 2.5 kW unit for a box room.
- Range: flagship models are quieter, smarter and more efficient, and priced to match.
- Distance: a few metres of pipe are normally included; loft routes or long runs add labour and copper.
- Height and access: high brackets, flat roofs, scaffold or restricted parking take extra time.
- Power: a new circuit is standard; an old consumer unit may need upgrading.
- Drainage: if water cannot fall naturally, a condensate pump is added.
- Building fabric: listed walls, stone and decorative finishes need more care.
What a proper quote should list
- Every unit by make, model and kW, with SEER and SCOP ratings
- Pipe length allowed for, and the cost per extra metre
- Brackets or stands, trunking and the condensate route
- Electrical work, pressure test, vacuum and commissioning
- Warranty terms, lead time, payment stages and validity
Keeping the price sensible
- A wall-mounted split is the most cost-effective option for most single rooms.
- Placing indoor and outdoor units back to back shortens the pipe run.
- Doing two or three rooms together on a multi-split avoids repeat call-out and set-up costs.
- A video survey saves a visit and speeds things up.
Prices in Cambridge
Our Cambridge quotes include travel anywhere in the city and South Cambridgeshire. The things that most often push a Cambridge price up are access: rear-yard-only terraces, flat-roof mounting, long pipe routes through lofts in period houses, and the extra care needed in listed buildings.
Commercial jobs in labs and occupied offices sometimes need out-of-hours working or extra protection, which we price clearly as separate lines.
What it costs to run
With electricity at 26.32p per kWh under the Ofgem cap from 1 October 2026, cooling a room with a 3.5 kW system costs roughly 7–8p an hour after the first warm-up. Using it as a heater costs around a quarter of the price of an electric radiator. Check your own numbers with the running cost calculator.
