Orthodontists in the UK who specialise in TADs and bimaxillary protrusion?

Had one round of braces with no help to my protrusion as my ortho convinced me against extracting. My teeth are now straight but I have seen that people with similar cases to me have seen significant improvement through TADs and extractions. Has anyone else in the UK had a similar problem and can you point me to any clinics that may be particularly experienced in treating this kind of case?
