Garden room and home office air conditioning in Putney
In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep. Garden offices used every day in Putney need cooling in summer and efficient heat in winter.
We check the armoured supply cable on every Putney garden room before quoting. Putney sits around 5 miles from central London, inside our London area. Postcode districts we cover here include SW15.

Planning and permissions
For most houses in Putney, 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
On a survey in Putney 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. A survey in Putney 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.
