Why globe replacement is not a small favour
Changing a globe looks trivial and is regulated for reasons that are not visible from the ground. The fitting may be a type requiring isolation, the circuit may not be what someone assumes, and the work may sit at a height that needs proper access. A person doing it once safely and once carelessly has the same appearance from below, which is exactly the problem with informal arrangements.
There is also an insurance dimension. A cleaning provider performing electrical work is operating outside what its cover contemplates, and a site relying on that is relying on nothing. Keeping the exclusion absolute is not officiousness; it is the position that leaves both parties protected. Where a building has many fittings needing attention, scheduling an electrician is faster than it sounds. Where a building has many fittings, an electrician working through them in one visit is usually cheaper than several separate call-outs.
