Does anyone know what happens re LGPS if you change LA?

I have c. 10 years in the Essex Local Government Pension Scheme. I've been offered a job by a neighbouring LA who also offer LGPS. Will both pensions be amalgamated? Does it matter?

The administrators will likely be different. Have a look on the LGPS website under the "transferring in" section. It will explain about joining two periods of LGPS membership together.
