What is the average costs of cosmetic dentistry in UK?

I live in Canada but am wanting to get my teeth fixed with braces/Invisalign’s and veneers. I have spoken to my dentist here and it will be about $14,000 Canadian for the entire procedures. So i’m looking beyond my own country but don’t want to go to Mexico or somewhere sketchy that I don’t speak the language. I am wondering how much approx (I know it’s different for everyone) does braces/Invisalign cost in the UK? Thank you
