Replace dimmer switch with standard switch

A blue
A brown 

B blue
B Brown

C Brown
C Black
C Grey

They need to go in the same places as they came from.  Unfortunately you didn't mark them so without a meter to test what each wire does who knows.

Convention for C is brown to COM & black & grey to L1 & L2 but who knows how someone has actually wired it.

A & B you need to know where they go / come from.

You didn’t take a picture of the previous switch before you removed it, I suppose? I mean the wires, not the front.

Unless you recorded which wire went where on the old dimmer, I think the answer to your question is "no".

Someone will need to trace where each of those wires goes, in order to work out how to wire it up again.

You will also need to connect the circuit protective conductors to the Earth terminal on the switch. This is vital. 

And LAP is cheap rubbish. Abysmal quality. It's a Screwfix own brand.

could be anything. I could list loads of ways to wire it up, but would need to know how the other ends of those cables are connected.
at a guess, the most probable way of wiring, assuming all conductors were wired into the switch and none were in a choc block in the back of the switch I'd go for this:
1st switch, brown in C, and blue in L1
2nd switch, brown from the 3core+E into C, Black & brown from the T&E into L1, and Blue & grey into L2
and remember to earth the switch , you can either fit a new bit of cable between the backbox & the switch or just remove the cables from the backbox and wire them directly into the switch.
turn it on & see if it works, you may found you have mixed the 2 x twin & earths up if so that will become apparent when the 2 way switch on the other side of the room operates a different light
