The answer is 2 GoodGymers - as per GoodGym policy - both to ensure safety of all concerned, and also so that one can take a photo of the task being done :-).

Mrs I’s hallway was very dark when we arrived. The bulb was 'on' but it was certainly very dim. She had an inkling that it was just a faulty bulb as the fitting had recently been installed by an electrician. With a handy set of steps and a new bulb all ready and waiting for us, we made light work of brightening up her home.

Mrs I was very grateful for the help and thanked all of GoodGym.
