Question to the Department for Work and Pensions:

To ask Her Majesty’s Government how many letters they have written to (1) women, and (2) men, to inform them of changes to their state pension age; of those letters sent out, how many were returned undelivered; and when letters were returned undelivered, what efforts they then made to contact those individuals.

Between April 2009 and March 2011, the Department mailed all women born between 6th April 1950 and 5th April 1953, informing them of their State Pension age under the 1995 Pensions Act. This involved sending 1.16 million letters to the affected females.

Following the 2011 changes DWP wrote to all individuals directly affected to inform them of the change to their State Pension age. This applied to women born between 6th April 1953 and the 5th of April 1960 and men born between 6^th December 1953 and 5^th April 1960. These letters were sent between January 2012 and November 2013. This involved sending 5.77 million letters to the affected males and females.

We do not have the total number of letters returned undelivered over the course of all the exercises. However, I can confirm we have a robust process in place to review all incorrect address returns and properly scrutinise and update customer account details when an address is confirmed. For State Pension customers, this process includes re-establishing contact through Local Authority Social Services or a DWP Visiting Officer.
