You'll notice that I said "the absence of a JSA claim supports the view" rather than "proves". Not suggesting that the claim is paid without evidence – a GP letter or something from another health professional confirming the continuation of a health condition would do the job nicely. Simply pointing out that your original response…
"no – it a requirement that they sign on/register with the jobcentre plus to retain worker status.
the worker status starts again in November when the new employment started"
…is perhaps a little restrictive. There are clearly times when a claimant in the situation described by the OP could continue to retain their self-employed status.
Thanks for the explanation of how subsidy works btw!
