Install light fitting - new build flat

I want a new light fitting switched for the one that came with the flat. I've included photos of both. I read through the instructions and it seems fairly straightforward (included photo of wiring step which makes me think nothing crazy). I have done this before a few times but I've just moved from London and am without my things till Feb 2025 (insulated screwdrivers, voltage checker, stepladder, drill) so I need someone else to complete task. Not sure on budget as still thinking in £, task is hopefully straightforward.
