The 2 year rule ensures that where you leave employment having completed at least two years membership of the scheme, then you must be be given a preserved benefit on leaving service (based on both employer and employee contributions). If your period of inclusion was less than two years then there is no obligation on the Employer to grant the benefit of their contributions ( but they can if they wish).
So in relation to your 11 months, it should have been decided at the time you left what you entitlement was:
- did you get a full deferred benefit
- did you get a benefit based on your contributions only, or
- did you opt for a refund of your contributions.
If you have some form of preserved benefit then you should be able to take a Transfer Value into your current scheme. But it may depend on whether the the current scheme can facilitate such a transfer.
