I have had feedback and thought it would be easier to have one post with the main information regarding what agencies I am signed with and what photographers built my portfolio, so you can pick and choose.
I am signed in 15 agencies so far:
Real London Casting @rlcasting
Source Models @sourcemodels
IMM Models @immmodels
Sandra Reynolds @sandrareynoldsagency
Lucinda Leon Management @lucindaleonmanagement
Flair Talent @flairtalent
Reality Check Management @realitychecktalent
Crumb Agency @crumbagency
Contact Models @contact.models
SOS Agency @sportsofseb/
Bec Models @bec_agency
Eden Model Management @edenmodelmanagement
T-ypo Talent Agency @typoagency
My portfolio is the result of shooting with the following photographers, sometimes several times, and I recommend them all. One rule for your portfolio, you need to update it with new photos at least once a year.
Andrew Clifton Brown @andrewcliftonbrown.photography
Ivan Weiss @ivanweiss.london
Jeff Marano @jeffmaranofilm
Mondi Dauti @35mmondi
Hannah Couzens @hannahcouzensphotography
Michael Wojcik @michaelwojcikphotography

Laurence Taylor @laurencetaylorphotography
Ivan Gener @igener
Temitope Ifekoya @ifeth90
Now, there are plenty of models groups, photographers groups, job offers, platforms online. I know it can be overwhelming so I tend to stick to a couple of them so I am not inundated.
I use, on top of my signed agencies:
https://www.starnow.co.uk/ I like it as you can get some really cool jobs, some TFPs with photographers (time for photos) and get involved in projects that you wouldn't find anywhere else. You also have a lot of students with low budget or no budget at all looking for models/actors and it is a great way to experience something new with often very talented people.
https://www.wegotpop.com/ I used to do a lot of extra jobs and still have my account as you can sometimes receive exciting requests, or better, featured role requests. Acting was not a primary desire but I never say no to a challenge.
This post will regularly be updated over time and experience.
