can anyone please tell me is there a regulation in the 17th edition thats states you put upstairs lights and downstairs sockets on one side of the board and downstairs lights and upstairs sockets on the other side of the board?

In simple words, yes. Basically it says that circuits should be segregated so that in the event of a fault, the least amount of inconvenience is caused thus having the layout that you have mentioned is implemented as a good practice

The 17th Edition requires most if not all circuits in domestic premises to be RCD-protected. There have been a number of suggestions as to how the consumer unit may best be configured to comply with the Regulations, the most common being a main switch with RCBOs protecting each individual circuit. However, another suggestion favours a main switch with two RCDs protecting separate DIN rails. If careful consideration is given as to what each bar will control in the way of upstairs and downstairs lighting and power circuits, will this configuration comply?

Yes, as long as the division of final circuits between the RCDs is carefully considered so as to minimize the consequences of unwanted tripping. Separate RCD protection is not necessarily required for each circuit of an installation but, in order to minimize the likelihood and consequences of tripping, a single (‘front end’) RCD should not be used to protect all the circuits.
