How this tool works
Enter the contractual dates
Start with the payment due date and the final date for payment stated in the signed subcontract or certificate. The planner adds the payer-notice period to the due date and counts the pay-less period back from the final date using calendar days.
Calendar-day arithmetic may differ from a contract that defines working days, excludes holidays or uses a special service rule. The England and Wales Scheme contains fallback periods in defined circumstances; this planner does not pre-fill them as universal contract terms.
Keep a payment-cycle record
Save the resulting dates with the application, payment notice and service evidence. For repeated valuations, use the actual dates and periods for each cycle rather than assuming the same schedule applies after a variation or contract amendment.
Assumptions and limitations
This is a browser-based estimate using the figures and periods you enter. It does not verify a contract, decide legal validity, calculate tax liability or replace current HMRC guidance. Reviewed 7 October 2026.
Frequently asked questions
Does the planner know my contract terms?
No. Enter dates and periods from your signed subcontract. The result is calendar-day arithmetic only.
Are Scheme notice periods universal?
No. Scheme terms apply in defined circumstances. Check your contract and jurisdiction.
