# Notified sum

The sum established through the applicable payment-notice mechanism, subject to any valid and timely pay less notice.

## Further detail

Read this alongside [section 111 of the Housing Grants, Construction and Regeneration Act 1996](<https://www.legislation.gov.uk/ukpga/1996/53/section/111n1>).

The notified sum arises from the applicable payment-notice mechanism. It is not always the amount of an invoice or the ultimate value of the work. A valid and timely pay less notice can affect the payment obligation; valuation disputes remain a separate issue.

Identify the operative notice and relevant cycle. Our [Subcontract payment assessments](<https://www.quantsurv.com/quantity-surveying?service=%2Fquantity-surveying%2Fpayment-applications-valuations#client-types>) service keeps that sum distinct from the application and underlying valuation. [Overdue payment recovery](<https://www.quantsurv.com/claims?service=%2Fnot-paid%2Fservices%2Flate-payment-recovery#client-types>) addresses a properly due sum that remains unpaid.
