I would definitely recommend going to an ENT (or plastic surgeon) who specialises in rhinoplasty + septoplasty.
I haven't had any experience with them, but personally I'd avoid places like Transform, Harley Medical Group, MYA etc - just because I feel like (from what I've heard) you don't have much say in your surgeon + a lot of them perform a wide range of surgeries each year. So they might recommend a surgeon, but they may not have necessarily done a rhinoplasty in that year and have mostly performed boob jobs or something. I've also seen horror stories about Transform specifically, where they've end up with a very 'cookie cutter' nose, or still had issues with it after (like them not fixing a deviated septum, or it basically collapsing). I remember reading an article on their surgeons being sued as they often fly them in from abroad, and them not getting aftercare or compensation they were entitled to because of it.
I'd suggest looking at your local Spire or Nuffield Health hospital to see what surgeons they have there. It is a bit more expensive than the more commercial places I think, but you can still do a payment plan.
