Split Cash ISA providers

Warslet

I’m thinking of opening a 1 year Fixed Rate ISA with a lump sum and want to add to an instant access ISA throughout the tax year with the same provider. 

Aldermore will allow the opening of both in the same tax year. Any others come to
mind please?

NatWest have never offered this across their ISAs. Their Portfolio Cash ISA offer has only ever been to customers with their HTB ISA as a means of being able to utilise the remainder of the customer's allowance that couldn't be used in the HTB ISA, and the customer could only subscribe to 1 other NatWest cash ISA. This is still available to customers subscribing to a NatWest HTB ISA.
