Hi Dan,
No worries.
The best bet would be to use our online application via our website, you could then copy & paste your spec onto the application.
You are able to put the date required in advance (including more than 30 days ahead) and you would get an estimate, but any application thats way ahead will need to be verified nearer the time that cover was required.
It's likely that the terms will not have changed, but all Underwriters reserve the right to alter terms when it's outside of their guarantee period.
Kind regards
Tony
