Luton Outlaws - Independent Message Board for Luton Town FC

Quick bit of Google research:

"For the purposes of rule 16(2) of the Land Registration Rules 2003 the specified period within which the requisitions must be complied with is 20 working days from the date of the requisition, but for most applications we allow a longer period of 60 days. The warning of cancellation is normally sent after 40 working days and explains how you can request an extension of time if you are still unable to reply fully in that time."

"We will cancel the application in its entirety if we do not receive a full reply and a successful application for an extension of time to reply is not made."

(both from https://www.gov.uk/government/publications/requisition-and-cancellation-procedures/practice-guide-50-requisition-and-cancellation-procedures)

So from my basic understanding, the warning would have been issued before the deadline (day 40 out of 60 days) and if it hadn't been completed within the original 60 days or an extension hadn't been sought (and granted) then they would have cancelled the application by now. They haven't, so everything is fine.
