our 70’s semi has an old fuse box that i’d like to replace with a nice modern and safe consumer unit. i’d also like a couple of extra rings put in, one for the garage (where the fuse box is located) for running tools, lawnmower etc, and one in a cupboard that houses hifi, computer and network equipment. this cupboard backs onto the garage just next to the fuse board so just need to drill a couple of holes and we’re good to go.
access to the existing fuse box is clear, and all the wiring in place gives no cause for concern so i’m hoping this is a simple job.
so, if i fit and wire the rings in the garage and cupboard leaving wires un-connected ready for the spark to check and commission when he changes the consumer unit, is that likely to pose a problem? and how much should i expect to pay (obviously i’ll get a couple of quotes, but good to have an idea)
