coventry: remove fault electric shower, and fit new shower (supplied) (ended)

I need a strip light fitting in the garage. Fuse box is on the wall outside of the garage. No light currently exists.

My electric shower has stopped working, it switches on and will just pump out cold water etc, when checking the fuse in the fuse box, it had gone off however when trying to put bsck on it automaticly swithces off, i have purchased a new electric shower, so would like old one taken out and new one fitted, as been advised element has gone , so that is why fusing thanks

I am in the process of 1st fitting the wiring for an extension. Once the plastering is done I will probably 2nd fix too. But I'm not too excited about connection to the consumer unit. So I hope a qualified electrician will look at my work and say "that is fine" and then connect the wires to the consumer unit. I have run 3 three new circuits: one in 1mm twin core + earth for lights one in 2.5mm twin core + earth for plugs one in 6mm twin core + earth for range cooker All existing circuits have been approved and passed recently by another qualifies electrician.
