Having had a quick read, my view is that the provision is identical irrespective of age.
For [b:a4675479f8]HBR 7(6)(e)[/b:a4675479f8] to apply, [b:a4675479f8]HBR 7(8 )(c)[u:a4675479f8](i)[/u:a4675479f8][/b:a4675479f8] must be satisfied. That requires that the delay in moving in [u:a4675479f8]must[/u:a4675479f8] have been [u:a4675479f8]necessary[/u:a4675479f8] for the dwelling to be adapted for the disablement needs of the clmt, or a member of the family.
None of the other options under [b:a4675479f8]HBR 7(8 )(c)[/b:a4675479f8] matter – sub para [u:a4675479f8][b:a4675479f8]”i”[/b:a4675479f8][/u:a4675479f8] must be satisfied.
As an aside, carpeting / decorating etc do not count as adapting a dwelling for disablement needs.
Hope this helps.
