Scanning a few Notts judo results sheets, there's no obvious stand out club. The university Judo club is pretty decent, but I don't know if they'll let non-students train with them. There's a list of all Notts judo clubs here: https://www.nottsjudo.org.uk/clubs.php with contact details etc.
I've changed my mind. Ryecroft has at least 3 Senior GB squad members (and a handful of others with ranking points). I'd train there.
