A reading of the document shows the following:
1) The Notice section specifically refers to Approved Plan No.: OW1010/06, which plan relates to the latest extension (so based on your answer we would then only have to evacuate the extension).
2) A claim is made that a site visit was made by the Inspector on 20 February 2012. The claim is unsubstantiated by evidence - there were two persons at the premises all day that day, nneither of whom remembers such a visit, and no calling card or other document was produced.
3) The document is not signed
4) The contact telephone number given for the relevant inspector is incomplete
Given the deficiencies listed above, is this document even legal?
If not, I assume I could ask them to visit the property again in person at a pre-arranged time to properly serve the notice, whereupon the 30 days compliance would run from the second visit - would that be correct?
I can post a picture of the document or email a PDF if that would be useful.
