I'm about to change ISP, as one does (from Talktalk to Sky) and the new one goes live tomorrow; I have a new freebie router ready to plug in. I'm slightly concerned that the change might upset my currently well-behaved LAN. Although this runs from an Airport Extreme attached to it in bridge mode, the ISP router is still my DHCP server, with my Unitiserve allocated a static address from within the DHCP IP address range. The streamer and everything else is all on DHCP.
Should I just plug the new router in and take it from there, or is there anything I should do first? Should I, for example, reset the US to dynamic? I might be worrying about nothing here - suggestions welcome....

Depends how you have your serve set because you are saying it has a reserved dhcp addy so would not be static.
If it is indeed static as well (No need btw) then yes return it to dhcp because your new router may not even be the same IP range.
This goes for anything with a static address on the network.

Thanks, I'll remove the fixed IP address from the US before I change over. My router's DHCP server describes it as a static address, but it's just a fixed address from within its range. I have not, for example, used the Set IP tool to fix anything (I can't, as you need a PC and we only have Macs.)

Chris, congrats, dynamic addressing is the sensible choice unless there is some legacy router issue preventing it from working.

Thanks Simon, I put the US on a fixed address on my last router when the SU often couldn't find it (your suggestion, IIRC) and it seemed to help, but it's seeing it OK now, so I'll observe the 'If it ain't bust, don't fix it' rule for the time being.
