Air conditioning for extensions and kitchen-diners in Lowestoft
Low rainfall and long summer days in the East of England make south-facing rooms the first to overheat. For a kitchen-diner in Lowestoft, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Lowestoft, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Our Suffolk coverage takes in Lowestoft, about 38 miles from Ipswich. Homes in NR32 are all within our coverage.
Prices in Lowestoft
Guide prices around Lowestoft run from £1,595 to £4,995 per space including VAT. That is above the UK middle, mainly because labour and access cost more in the East of England. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,295–£3,195 here.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
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 Lowestoft, 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
Surveys in Lowestoft cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. On a survey in Lowestoft the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
