Pete - sorry, but you are wrong. It does not include the "up-to-date-rules", it's too old.
It pre-dates the current version of the Wiring Regulations, and there were significant changes in that.
It still talks about a very early version of Part P of the Building Regulations.
It is years out of date - as I said in my review, nobody should buy it, there are up-to-date alternatives available, and really this should be withdrawn from sale.
