Wall-mounted air conditioning in Boston
In the East Midlands, one system that cools in summer and heats efficiently in winter makes good use of the investment. Where a home in Boston faces the street, the outdoor unit usually goes at the rear, out of sight.
A single wall-mounted unit is often all a bedroom or sunny living room in Boston needs. Our Lincolnshire coverage takes in Boston, about 27 miles from Lincoln. We cover PE21 and the streets around them.
Prices in Boston
Budget around £1,095–£2,845 per room including VAT for wall-mounted air conditioning in and around Boston. It is a touch below the UK middle, as trade rates in the East Midlands tend to be. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. Typical Popular work (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) lands around £1,495–£2,045 in this area.

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
For most houses in Boston, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. Surveys in Boston cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
