Hullo
I am shifting my kitchen to be internal in a 2nd floor flat.
1) I am putting in an extractor fan at ceiling level does it have to
be a 30 or 60 LPS ?


I think from memory the bigger size.


2) I have an internal window to a bedroom, I will be closing this:
Does 12.5mm plasterboard have the required fire retardency. Can I use
glass bricks/special glass and if so will it meet regs ?


Pretty sure thats OK., remember to provide for ingress of fresh air or
the fan won't work.

And put in LOTS of LV spots to make it bright and cheery.
