Since April 2006 the LGPS Regulations have allowed employers the discretion to release scheme members' benefits whilst keeping them employed on reduced hours or at a lower grade. This is known as flexible retirement.
Once you reach the age of 55 your employer can agree to the release of your benefits thereby avoiding the perceived 'cliff-edge' that many face at retirement. Benefits released early may be subject to reduction if you do not satisfy certain conditions of the scheme, although your employer also has discretion to waive any reduction that may be applied.
