Doing the google search for "
www.inverclyde.gov.uk" + Intimations + pdf does the trick

I'll now download all the Intimations so I have them on my computer for when I need them.
I did email the Watt Institution yesterday - here is their reply:
"Many thanks for your recent enquiry. Our intimations are currently not available online as the PDF format they were developed in no longer meets accessibility standards for public bodies in the UK and they have to be reformatted which is quiet a task given the amount of data we had online.
If you let me know what you are looking for I can forward the relevant documents directly to you.
Kind regards."
Thanks everyone for your responses.
John
