Does you Nintendo Switch have problems with the joystick drifting?
What that means is that your controller is moving, either up/down or left/right, without any touching of the joysticks. So if you want that repaired, Jock IT can sort that out quick quickly.

The cost of these repairs are really value for money.
To have both joy-cons repaired with new joysticks, the cost is £25.
If you just want one repair, it's £15.
