Have been meaning to open a Savings Account for some time. We have no banks left in town but we have the convenience of the Suffolk Building Society here. Staff were very helpful in opening the account and always extremely pleasant when I go in to put some money in my account. Thank you.

Always like to support a small local building society over the big banks. The service is always excellent, the staff knowledgeable about their products and they offer a good range of competitive accounts. Our local branch is Sudbury and we have always found the staff friendly and efficient.
