If you're not willing to move things around then there really are no options.
I opened a Nationwide Flex Direct this year but that only lasts 12 months.
I have Santander 123, TSB Classic Plus, Lloyds Club and now Nationwide all maxed up to get the interest, and move money around by standing order to meet the minimum pay in requirements. I also have a regular saver with the TSB, Nationwide, Santander and Lloyds but they only last twelve months too.
