If you like giving you money away

Just invest with the Santander investment hub. Their Atlas products are rubbish. I blame myself for leaving it in their hands, have taken steps to remove and reorganize under my own control. Big disappointment 5 years wasted. Reviewed on: 26th July 2023

Worst ISA on the market

Been in Santander ISA for 5 years £70000 invested have lost over £1000 - absolute rubbish - do not even consider this company as an investment - check out Vanguard Reviewed on: 18th July 2023

Worst investment advice ever

Cold called by Santander. Financial advisor would help me invest. Charged me £750 plus £300 a year to manage plus £150 per year for their 'hub'. Investment has lost 10% of its value in a year despite being 'low to medium risk'. Totally mis-sold. If anyone is thinking of a stocks and shares ISA with Santander then DON'T DO IT! Every month the value of my ISA goes down and down, its now even beyond their 'worst case' scenario. They are clueless!! Reviewed on: 10th July 2023

Absolute rubbish

Been with this fund for 5 years £70,000 invested - the return minus £250 - if you have any sense put your money elsewhere Reviewed on: 14th June 2023

Bes RTate

Santander had the best 1 year ISA rate this year Reviewed on: 3rd April 2023

Fuss free and easy to use

Always had competitive savings rates Reviewed on: 3rd April 2023

Great ISA rate

A great online fixed rate ISA easy to set up, staff in branch very helpful Reviewed on: 6th March 2023

Poor investment ISA performance

Since August 2021, my ISA and investment account have both consistently lost significant amounts of money, and are worth more than 20% less. Of course we know that investments can go down as well as up, but both of these have only gone down. Buyer beware. Reviewed on: 10th February 2023

Investment

Easy to deal with and explained all deals available Reviewed on: 14th October 2022

Worst investment I ever made.

Investment total has declined every single quarter since I made it. Have lost patience now, far better to leave under mattress!!!!! So angry with Santander!!!! Reviewed on: 22nd September 2022
