Payment notice checker

How to Use This Calculator

Enter the due date and final date for payment from the project timetable. Add the applicable notice periods and the actual issue dates. Select the correct counting basis. Leave an actual-date field empty only where no date is available for comparison.

Worked Example

For example, a due date of 8 October 2026 and a final payment date of 25 October, with five days after the due date and seven days before the final date, give deadlines of 13 and 18 October. A pay-less notice dated 19 October is one calendar day later.

Before You Use the Result

The result compares timing. It does not decide whether a notice has the required content or was served effectively, so retain the notice and service evidence for any live review.

For a project that needs a wider review, explore QSEC payment and valuation support alongside The Subbie QS support.
