It will be a basic workplace pension no doubt. There is no monthly reporting requirement for a defined contribution insurance based scheme. There is a requirement for contributions to be forwarded to the insurer by the 19th of the following month, but insurers are very very slow at bringing this to the attention of the members when payments are missed or delayed, let alone the PR. They wait a long time before taking that step.
It is an offence though. If it’s 6 months it’s a pretty serious problem. The employees will have had their personal contributions deducted from salary each month automatically.
Not unknown for it to be insurer error and Aviva have just had an absolute nightmare with their new systems simply falling over time and time again.
But yeah... looks like employer not passing on deductions from pay. Not good that.
