I think anything electrical these days ‘must be done by a qualified person’ if you read the instructions, but in practice electrics are pretty straightforward.
Done about half a dozen lights over the last few months. Some are a piece of piss, some are fiddly as fuck. The two we had from Wilko were a nightmare because it was basically a box of electrical components and the light fitting in many pieces. But it’s basically like wiring a plug up twice, on the ceiling.
