I should know this but a little confused with the wiring of my hall way lights. Downstairs there are two switches for up and downstairs lights, whilst upstairs there is just one. I ideally would like to replace the switch upstairs with a two way one, so I can turn off the downstairs also, but a bit lost with the wiring.

There are two red wires both going into one side of the switch. A black and blue wire both into the second part and a single yellow with red big sleeve into the third. With a yellow/green wire not connected.

I assume the sleeved one is the control cable and so I would just need to split out the other 4 (two red and black and blue) to make the two switches, is this right?

The blue one also has a red big sleeve on it.

I have a photo but it exceeds the max size, so I will find a way of making it smaller.

When you make a post, if you scroll down after the "submit" button it says
"For help with adding images or resizing them please click here to see our help section"

Sorry but your assumption is wrong. In order for it to work as you want, you need another 3 core and earth cable.
Search for 2 way switching.

Some switches today use a wifi link. [quote]The Quinetic wireless grid switch is compatible with MK grid plus system
and can be installed into MK grid plus plates.

It can be used with the standard or with the dimming Quinetic receiving controller.

It has a built-in micro energy generator - when the switch is
pressed the kinetic system transforms the movement into energy.

This transmits a signal to the receiver
to turn the lamp or other load on or off.

This solves the issue of having to install switch wiring
which has been a problem ever since the invention of the lamp.

Can be used along side mains voltage gridswitches
