The Moneyfactscompare.co.uk Pick of the Week showcases the best of the latest products or rate changes to hit the consumer finance market, ranging from mortgages to savings accounts. This week I've analysed the following deals, along with their perks.

 

Savings

Castle Trust Bank

Castle Trust Bank has increased the return on its 3 Year Fixed Rate e-Cash ISA, and it is now a market-leading rate of 4.16% AER.

The return is comfortably above current inflation forecasts making it ideal for those with at least £1,000 to save and looking for risk-free guaranteed real returns that aren’t liable for tax. Savers also benefit from a little flexibility as they can make additional deposits for up to 14 days from account opening.
