I'm pooing my self as i have lighting circuit, heating system, and data points to do within 2 hrs tomoz :/ nt sure if this is possible but ill try my best, i've left these last, because i'm unsure of them :/ need some advice ive added a pic of how i think i shud wire the lights but im not sure where to put my 3core in etc.. any advice?

I take it that's two way switching with intermediate. So three core between first two-way and intermediate and between intermediate and second two-way (assuming that's how you've been taught to do it). Then just take the two core switch feed to the light from either of the two two-ways.

That sounds a plan, but im stuck because ill be using a twin & e to the 1st switch, i will need to carry the neutral from the db all the way to the light, which cable do i use for the neutral 3 core with the grey or what hmmm :/
 
i've been taught different to that, think i have to feed 1st switch 1st, then some how tke a neautral to the light from the neutral in the board, then from the 1st switch to the intermediate in 3 core then from the intermediate the the last 1g 2w in 3 core again.

i think i cud use the grey as a neutral, please correct me if im wrong?
 
I think you want something like this:

I have used grey as neutral because I think it is advised as a neutral colour to avoid confusing it with black (but I always use black as neutral, sleeved blue)
 
I can't remember how I did my lighting circuit now. I know it was a really odd way/over use of cable but thats what it said.

Your data is easy, gun each point the same and according to the colour code on the fixing. you want B not A

Heating system is so easy as long as you can read a wiring diagram. It's very clear, just remember to mark cables when you pull X cables in so you dont cross wire them. Terminals on the diagram wernt in the same order on the fixings for some of them for me so watch out for that. it's all marked up.

Make sure the DOL thermal overload setting is not on 0
