Also if installing new cable, there are requirements for permitted safe zones of cables.
The cable must be either RCD protected or mechanically protected, if buried less than 50mm within walls.
Also there are building regulations(Part A), concerning holing of joists and depths of chases.

some websites show switch live to L1 and others show it goes to L2 can you place it on either terminal or is there a specific one please help guys

thanks

Please spend some time learning what switches do, what goes on inside them, how 2-way switching works etc.

That's a far better way to proceed than diving in without understanding the things you're fiddling with and trying to get help as you get stuck going along.

Live goes to L1 and Switch Live to L2.
For standard two switching your three core and earth cable's conductor colours must match the terminal markings in each switch. E.g. 3 Core brown to Common in both switches etc.

thanks does it make a difference if you put live and switch live the other way round

Not in my experience.

Your switch will be upside down unless you fit it upside down.

Or unless you wire the other one to match. Some people are anal about whether rocker symmetry should mean off, or not.

Have you actually got a 2 way circuit?

 

[ban-all-sheds]

Well if he hasn't it definitely doesn't matter which way round he connects L1 & L2!

But you should know that.

You should know how switches work. You should understand how they are used to do 2-way switching.

You shouldn't attempt electrical work on the basis of blindly following instructions to put-this-wire-in-that-hole without a genuine understanding of why.

the picture makes no sense to me

Then you should keep reading about how things work until it does make sense.
