Santander has launched an exclusive competitive ISA for new and existing 123 current account and credit card customers.
The two-year fixed rate cash ISA pays 3.30 per cent and savers are required to invest from £500 up to the ISA limit for the 2012-13 year, which is £5,640.
The offer is available to existing 123 customers or to new customers when they open a current account or are accepted for a new 123 credit card.
The ISA account accepts transfers-in from any provider and the account can be opened and managed in-branch or over the telephone.
Matt Hall, Head of Savings said: “It’s important for savers to take advantage of ISAs as early as possible to maximise their tax free returns. This two year ISA offers a market-leading rate and gives customers the peace of mind of knowing exactly what they will get back.”
