Chosen Solution

I tried taking my switch apart to look at the LCD screen but I’ve threaded one of the screws on the right hand side bit that holds a joycon. Is there anywhere in the UK I can send this off to be repaired. I only need the screw taking out so I can have a go at repairing the joycon sensor rail myself.

@mrjuggles we usually do not make any recommendation for any repair shops. Recommendations are never objective since they do depend on personal preferences. What we can do, is to recommend those that are known to us on iFixit as reliable repairer and are not trying to promote their own businesses on here. For your geographic area I would contact either this user https://www.ifixit.com/User/2113661/dani… or this one https://www.ifixit.com/User/4041651/Nige… I am certain that if they can’t help you, they will at least provide further guidance to you.
