Santander

If you opened a Santander Direct ISA Saver last year, check your rate now. If you haven't upgraded, it could now be paying as little as 0.5%.

Borrowers can now get 18 months interest-free spending for a year and a half, plus up to 3% cashback with Santander's new 123 credit card deal.

Savers can get up to 2.75% tax-free interest on cash put into an ISA. But with the deadline looming you need to use your ISA allowance now or you'll lose it.

If Barclays, Lloyds or RBS/NatWest have offered you payment protection insurance (PPI) redress on a loan since 2012, you may be owed £100s more.

Customers who sought investment advice from Santander could be due redress after the bank was fined almost £12.4 million by the City watchdog, which uncovered "serious failings" with the investment advice it gave customers.

Savings rates are at an all-time low. But with less than a month left to take advantage of this year's Isa allowance, should you be using it?
