I've generally been Nationwide however hacked off with their pitiful interest last year I opened a Santander 123 Current account which I fund from my Nationwide Flex a/c. Here's the spec :-

The current account that pays you cashback on your household bills and interest on your balance for £2 a month.

What you get

Monthly cashback on selected household bills.

Monthly interest of 3% AER (variable) on balances between £3,000 and £20,000.

Calculate how much cashback and interest you could earn.

To get cashback on your household bills and interest on your balance, just follow these steps:

Pay a monthly account fee of £2.

Fund the account with £500 a month (excludes internal transfers). A minimum balance of £1,000 is needed to receive interest.

Set up at least 2 Direct Debits. You’ll get monthly cashback on selected household bills you pay by Direct Debit

1% cashback on water and council tax bills and the first £1,000 you pay towards your Santander monthly residential mortgage payment

2% cashback on gas and electricity bills

3% cashback on mobile and home phone bills, broadband and paid for TV packages.

These cash backs more than cover the £2 fee
