Rolled-up holiday

12.07% on every hour

Agency and umbrella workers get holiday pay per shift, not per booked day. Clok tracks the pot so you can set it aside for time off — nobody else attempts this.

Student loans

Plans 1 / 2 / 4 / 5 + PGL

HMRC-accurate. 9% above each plan's threshold; 6% PGL on £21k+. Auto-picks the lowest-threshold plan if you have more than one.

Split allowance

Two jobs? Two tax codes.

Mark a workspace as secondary employment. Clok forces BR (or SBR/CBR) — matching HMRC. Your personal allowance stays on your main job where it belongs.
