No payment notice came. Your application might now be the notified sum.
The Construction Act runs payment on notices, and silence has consequences. After the due date, the payer has a short window, five days under the Act's default, to serve a payment notice stating what they consider due. If they serve nothing, and your application was made in the form and at the time the contract requires, your application itself can stand as the notified sum.

The notified sum is not a negotiating position. It is the amount that must be paid by the final date for payment, unless a valid pay less notice arrives in time to cut it. If neither notice comes, the full sum is payable, and an adjudicator can order it paid without ever looking at the valuation.
Three checks decide whether that is your position: was your application itself valid (right time, right form, right recipient, a sum and the basis of its calculation)? Has the payment notice window genuinely closed (counted from the due date under your contract's amended dates, not the standard form's)? And has the pay less window closed too, or is it still running?
If all three line up, say so in writing before the final date, calmly and with the dates set out. Most payers pay when the position is put clearly, because they know what an adjudicator will do with it. And whatever this cycle brings, fix the machinery that let it be a surprise: every one of these dates can sit in a register that counts down to it.
Where to go next
The free Notice & Deadline Register holds every one of these dates, counting down. Payment & Pay Less Notice Checking & Response reads what arrives, and what does not, against the contract each cycle, and the s.110B Back-Audit is for past cycles where this may already have happened unnoticed.
