Natwest

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.

The UK's major banks and building societies will be investigated by the Financial Conduct Authority (FCA), following a number of high profile IT failures, it's been announced.

NatWest and RBS have axed their credit cards with introductory 0% rates, replacing them with a new deal which charges 6.9% representative APR on transferred balances and spending. But you can get other cards which charge less.

NatWest, RBS and Ulster Bank are banning introductory bonus rates to get back to basics with simpler products. But MoneySavingExpert.com creator Martin Lewis says the move could result in even lower returns and less certainty for savers.

Customers of newly-created TSB have voted it the worst bank for customer service, according to the latest Banking Service Index from MoneySavingExpert.com.

Santander customers who use the bank's agencies will have to travel to branches instead from October, after it announced plans to close all 139 outlets in rural and suburban areas.

If you've been hit by the floods and are struggling with emergency costs and mortgage payments, you may be able to get help after leading banks announced support measures.

Update: 6 February 2014: The RBS Group has confirmed that any missing interest has now been credited to affected NatWest and RBS customers' Isa accounts.

If you're a customer of Lloyds, Halifax, Bank of Scotland or TSB, and were hit by this weekend's IT glitch which left many unable to withdraw cash and use debit cards – complain now if you've been left out of pocket.

If you've got a mortgage where interest is calculated once a year, you could save hundreds of pounds by overpaying in the next few weeks.
