Yes.
He even attended the (heartbreaking) Manchester Detrans event back in 2019, accompanied by Helen Islan (aka MimmyMum) so it’s not as if he’s unaware of the outcome of promoting transition to teenage girls.
He has stopped immediate prescribing at the first appointment (now refers on to one of his associated Gendercare endocrinologists) but there is speculation that that was purely due to professional insurance reasons, rather than a change of mind.
Weirdly, Lorimer was one of the people who reported the doctors Webberly of GenderGP to the GMC.
Almost all the private gender doctors in the UK have (or had) NHS gender clinic day jobs (Webberley is a notable exception, hence, I presume, the reporting to the GMC as ‘not a specialist’)
Lorimer used to work in the London Adult GIC along with Dr James Barrett (colloquially known as ‘Charing Cross’ for historical reasons, currently operated by Tavistock & Portman and previously the West London Mental Health Trust) but now works at the fairly recently founded Welsh Gender Service based in Cardiff (Wales used to send all their trans patients to London).
I expect the transfer was partly to do with opportunities for promotion (as London GIC bossman Dr Barrett has an in-trans-community reputation for being controlling and old fashioned) and partly due to home life (Lorimer’s partner is older and iirc relocated to Wales for retirement).
Gendercare no longer ‘advertise’ via social media, as they already have more patients than they can cope with - waits for appointments are 6-8 months (according to the transgenderUK subreddit) - and as the main reason for going private is off-the-scale wait times for NHS GICs, longer than 6 months wait for private renders them unappealing.
Gendercare is little more than a website advertising a hub of doctors who refer to each other who all sort their own private appointments/waiting lists.
The roster of available doctors changes from time to time and various other businesses with similar models have sprung up since Lorimer’s Tumblr days.
In Lorimer’s defence, Gendercare have never been a paediatric service and show no interest in becoming one. At one time they would see 17 year olds for diagnosis only but I believe with the expectation they were almost 18 and no prescription for hormones made until 18.
Nowadays they’ve tightened that up to only seeing over 18s (although they do seem to allow 17 year olds to make appointments to take place immediately after they turn 18).
There is certainly no indication that any of the Gendercare doctors would prescribe puberty blockers for minors, so that’s something (admittedly, Webberly has sufficiently lowered the bar that Gendercare restricting appointments to over 18s makes them seem positively moral in comparison).
FWIW most NHS paediatric specialisms start the the process of transferring to adult services from 16/17 (little bit of variation dependent on how physically-adult the child is, due to size of equipment etc). Where I am CAMHS discharge at 18 (into a black hole of never ending wait lists, so no one really gets seen unless they present at A&E in crisis).
From what I can pick up online, GIDS has been transferring to adult services from 17, possibly due to long waits between transfer paperwork being done and first adult appointments.
The long waits for transfer has previously left some older teens on blockers without hormones for longer than the NHS compulsory minimum of 12 months, which I guess would be fine if puberty blockers were actually ‘totally harmless and fully reversible’ but (as we on mumsnet well know) there is ever increasing evidence of catastrophic side effects emerging from various European countries, which is a very good reason to not leave older teens on blockers in a black hole between child and adult services.
Of course, what happens when a transferred teen actually arrives at an adult clinic may be a whole host of other issues, but that’s another post, another thread!
I am curious as to whether the Susie Green and Helen Webberly alliance ever conflicted with the Helen Islan and Stuart Lorimer alliance (Islan and Lorimer definitely seemed to be proper matey via my personal observations at the Detrans event)
