This doesn't help much, except to show that things look good for protonmail.
Protonmail doesn't appear to have IPv6 support while google does. It is
entirely possible that you're trying to send to google via IPv6 and you
don't have an AAAA record for mail.bristolweb.net. This would result in
SPF failing when an IPv6 connection is established.
This, of course, is just a WAG. If you want someone to review the
issues with google then you'll need to show headers and/or logs from the
connection to google. Protonmail headers doesn't really help for this.

I know that comment was not aimed at me but: I meant to include the
protonmail header at the outset but forgot. Sorry. Below is all the
header except protonmail's anti-spam section; I hope it helps.
