StiPP has 2 Plans: Basic and Plus Plan. You start accruing pension in the Basic Plan after you have worked for the same employer for 8 weeks. So You do not accrue pension during the first 8 weeks. In the Basic Plan pension can be accrued for 52 weeks - You can work during those weeks at various employers in the temporary employment sector. If You work at least one hour a week, this week is included in 52 weeks period. After 52 weeks Basic Plan automatically will change to Plus Plan. You can see detailed information about Your Plan in My StiPP Pension website.
