Employee cannot confirm their student-loan plan? Use the 2026 default only until authoritative details arrive.
Keep the starter answer, account confirmation, payroll setup and later SL1 as separate evidence. A temporary default must not become a permanent undocumented setting.
Direct answer
HMRC guidance says that from 6 April 2026, if an employee with a student loan cannot identify Plan 1, 2 or 4, payroll uses Plan 5 until an SL1 provides the correct plan; multiple plans use the lowest recovery threshold until notice.

Use Plan 5 only in the stated default case while waiting for SL1
Direct answer: HMRC says that when an employee cannot identify whether they have Plan 1, 2 or 4, payroll should use Plan 5 until an SL1 arrives. The default does not replace a known plan, an SL1 instruction or separate postgraduate-loan handling.
