Consolidate Accounts

I seem to have acquired many account, some with money in and some empty. I currently have the following current accounts:

FD Account - Personal
FD Account - BTL
Natwest - a few hundred rounds to pay for car servicing
Nationwide - Empty, opened for cheap mortgage deal and cannot close until deal finishes
Tesco- Opened for savings
Tesco 2 - Opened for savings
Metro Joint - Monthly spending
Halifax Joint - Recently switched from FD to get the £125 but that was it and already I want to move it back!

I also have the following credit cards:

Amex - for cashback
Barclaycard - For places that don't accept Amex
Santander - For foreign trips

I kind of think this is just a bit all over the stop and want to consolidate. I want to move the Halifax account back to FD as soon as possible. Close the Natwest account and open an everyday saver just to park the money I put aside for car servicing. Close the Barclaycard and open a FD credit card for non-amex accepting places.

I do just like opening the FD app and seeing all my accounts on one screen.Does this seem like a good idea? My switch to Halifax only completed today so is it a good idea to go through a cycle of DDs before leaving them?
