Efficient service & decent cashback payment speed
Aldermore seem to offer consistently competitive savings rates in my experience. The online application process for opening savings accounts and cash ISAs is as simple as it can be and the transfer of an existing cash ISA was handled electronically, meaning it only took 3 days instead of the 15 days it can take with some providers. Cashback also tracked quickly and was paid within 3 months. No complaints at all, hence my 5 star rating.
