Almost one million UK customers with savings accounts saw a boost in their interest recently, according to Britannia.
The company states that as Bristol &West's savings accounts were switched to the building society, the customers shared a £7.5 million interest rise.
Neville Richardson, Britannia's chief executive, explained, "We have achieved so much in a very short space of time and our three million members can now enjoy access to the full range of Britannia products and services through a network of more than 250 branches throughout the UK."
Mr Richardson adds that the weekend of July 1st and 2nd was one of the most difficult in the transition of the savings accounts to Britannia.
The integration of the businesses will be completed by the end of 2006, when Britannia aims to transform all former Bristol &West branches into Britannia branches, which is part of a £17million refurbishment programme.
Britannia is the UK's second largest building society and offers a range of products such as mortgages, personal loans, savings accounts, banking and credit cards.
