The spirit of 1.3.5 is that user software can autofill the address inputs.
If there is no clear and user agent supported HTML autocomplete
value/set of values for a UK address, i.e. if the user's software
either doesn't understand the value or it's applied inconsistently so
software may get half the fields wrong, then there's limited value in
trying to implement it at this time.
If the user extension either doesn't do anything or, worse yet, fills
in the form wrong, we haven't done the user any favors.
Your best bet would be to test out different values of autocomplete
with things like Google or other popular extension to see if you can
find a set of values that work consistently across browsers.
I'm guessing the requirement is meant to encourage or drive support
for these types of tools. While I like that thought, the biggest
drawback is that it doesn't go well with the unforgiving nature of
WCAG conformance.
