Where a home in Barnes faces the street, the outdoor unit usually goes at the rear, out of sight. We cover Barnes as part of London, roughly 6 miles from central London. That includes the SW13 postcode district.

The survey
A survey in Barnes 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.
