Waspi calls for immediate state pension compensation

But it had failed to act promptly after analysis in 2004 found the government's information campaign was not reaching the “people who needed it”, and recommended a targeted approach.

The report concluded that, if the DWP had made a “reasonable decision” in 2005 and then acted “promptly”, it would have written to affected women to tell them about changes to their state pension age by December 2006 at the latest.

This is 28 months earlier than when the DWP actually wrote to them.

“It follows that these women should have had at least 28 months’ more individual notice of the changes than they got,” the report said. 

“The opportunity that additional notice would have given them to adjust their retirement plans was lost.”
