Who can elect for 50/50?
As a member of the LGPS you can elect to pay into the 50/50 section at any time after you have joined. To join the 50/50 section, you must complete the election form and return to your employer.
There is no limit to the number of times you can elect to move between the main and the 50/50 section, and vice versa.
Your election once received by your employer takes effect from your next available pay period.
