The closure dates for the East Anglian branches of Norwich and Peterborough Building Society have been confirmed.

The name of the Norwich and Peterborough Building Society will have disappeared from the region's high streets by December.

Its owners Yorkshire Building Society have today confirmed the closure schedule for the 28 branches across Norfolk, Suffolk and Cambridgeshire, which will come with the loss of 136 jobs.

The 20 branches of Yorkshire Building Society – none in East Anglia – which will shut as part of the rebranding programme will be closed on Friday.

The N&P closures will be completed in four tranches, from September to December, in order to give customers time to switch to other providers, the group said.

The closing dates are:

Friday, September 29: Cambridge.

Friday October 20: Plumstead Road, Norwich; Sawston; Sheringham; Spalding; Stamford; Watton.

Friday November 10: Chapelfield, Norwich; Dereham; Fakenham; Huntingdon; March; Southwold; Thetford; Werrington; Whittlesey; Wroxham; Wymondham.

Friday December 1: Aylsham Road, Norwich; Bourne; Bowthorpe; Bretton; Bungay; Downham Market; Leiston; Market Deeping; North Walsham; Oundle.

A Yorkshire Building Society Group spokesman said: 'To help make the transition as smooth as possible, the 28 Norwich and Peterborough branch closures we announced earlier this year will be made in four phases, between September and December.

'This approach, which ensures closures are spread geographically across the region, is designed to minimise the impact on customers and ensure we maintain the high standards of service our members expect.

'We will be writing to all branch customers to ensure they will be informed of the relevant dates.'

Under the Yorkshire Building Society brand, the group will have a high-street network of 260 branches and agencies.

The plans, unveiled in January, also included the withdrawal of the N&P current account.

Customers initially reacted angrily to the fact N&P was not a member of the seven-day current account switching service, meaning they faced losing out on incentives offered by other banks. However, many have since flexed their guidelines in the hope of attracting new customers from N&P.
