1 Year Fixed Rate Cash ISA

Helpful supported service

I found the transfer of my ISA to Aldermore very straight forward. The only slight hitch I found was when I tried to add firther funds to my isa account from my bank account which could not be done in my account section on line. However the telephone support was very helpful and they explained how to set up a transfer from my bank account to my isa.

Straightforward Process

Aldermore were offering one of the best interest rates on cash ISAs. As always the process of opening an account was straightforward and quick. One very minor criticism - I had to read the terms and conditions and chose to print them out. I think a warning that they run to many pages might be useful. Otherwise no problems at all.

Already Had good experiences with Aldermore

I found the system to be user friendly in the areas that I used. Any contact with people was a pleasure and without exception they were friendly, helpful, courteous, efficient and knowledgeable. Extremely helpful. Thank you

Form filling on line

this was not as simple as initially I thought and if you are not competent at typing it was not difficult to be timed out and therefore have to start the whole process over again.

Fixed term cash ISA

I was looking for a new fixed term cash ISA to replace one which had recently matured with another bank. I had not used Aldermore before but the interest rates offered were competitive and I thought I would try them as an alternative. I was impressed with the very clear website.
