As my previous post was turned off before a conclusive answer, I have had to open up another post to answer the second part of my original Q
How do I carry out a 90 day report if as a U.K. Citizen I need to submit my 'old' passport for renewal ?
TIA again.
TLDR : Answer Summary
When renewing your passport as a U.K. citizen, you have a 21-day window to complete your 90-day report. You can submit the report using your current passport details and then proceed to apply for your new passport. Alternatively, you can write down your old passport details on paper and store them for reference if your new passport takes longer than expected.
