Tiling floor at 45 degrees

[On one]

Hi All
I put a rough price in on a 48m2 multi room floor a few months ago given that it would be standard 90 degrees to the walls, the rooms are most likely nothing square,nothing parallel,etc,etc
Now I have heard that the customer might be going at 45°to the main wall with the floor tiles.
Now in all my sheltered life, having only done 1 job at 45°how much % if any would you add to the labour costs?

size tile?

Most likely a 500mm x 500mm

Is there skirting on?
If not I'd go with your original price if it was any good.

I'd add around 30%/40% extra labour

Nope, no skirting fitted yet

Lots of tolerance then, 48sq Mts so money to be made.

I normally add 20% extra as a general rule for diagonal

Could you not do a border around the room just to square off from the walls.
