I have always found Nationwide to be fair and honest, and one of the big attractions is there is no lengthy wait to speak with foreign call centres.
The saving rates are comparable, and, being a building society, they have no shareholders so are focused on their customers rather than making profits for other people.
In have been with them for many years and as my saving focus has changed, I have always found they have a suitable product.
They manage alternative investments in collaboration with Legal and General too
Excellent customer service and British call centres
