Frequently asked questions
How long does installation take?
Most home battery installations are finished within a day, depending on the size of the system and where it is being fitted. We will confirm the timescale with you before any work begins.
Where is the battery installed?
Home batteries are usually fitted in a garage, utility room, loft or on an outside wall — somewhere out of the way and well ventilated. During your free survey we will agree the best location with you before anything is fixed in place.
