How was the old one wired up?
Have you still got it? can you show a photo of the back of it - explain what wire went where if you can?
Tip: Always photo before as well as afterwards.
Also the switch plate itself needs a sleeved earth wire connecting to it, this can be taken from the earth connection that is on the back box.

Make sure you have the same colour wire in the L1 (single terminal end) on both switches.
If it is red at the other switch, swap it with the yellow. You may mix up the reds otherwise.

I would swap yellow and blue
These manufactures don’t help calling com L1

A picture of the other switch is essential, quessing is not the way forward.
Moreso if the other switch is a Multigang

What other switch? The one downstairs? That has 3 on. 1 for outside light. 2 for Hall. 1 for upstairs
Do you have a multimeter? a little testing is required, to identify which cable is which.
No. It’s looking like I’ll have to leave it as it is.

Aren't they all on holiday?there are usually a few knocking about down the pub or on street corners.
Yes. but i would prefer you leave it if you dont feel safe as theres a lot of wires in it as its 3 gang.
Basically in the switch you show there is two main cables,
Cable 1 is 2 core and Earth to the light fitting this contains a
RED
BLACK with a RED oversleeve
That looks connected as normal
Cable 2 is 3 core and Earth to the other switch this contains,
RED
YELLOW
BLUE
As cable 2 is going to the other switch, it could well be, at this other switch where its connected wrong, did he also replace that switch.
The red core could be carrying a Linked Live Feed to the other switch, to power the outside light or hall or even both.
As thats a 3 gang switch, there is likely short linked wires as feeds to the other switches, so it could all be a bit complicated to sort out, if it had been a single switch then as suggested in post 3 by EFLI would likely have sorted it.
He only replaced this one. As you can see not that good at diy. Thats really well explained but seems complicated. I’m guessing I best leave it as it is until I can afford an electrician.
No problem whatsoever to anybody who should be fiddling with light switches.
