hey there
i had the same thing happen to me but it was my bottom teeth thast i really had a problem with as i had my top teeth done and didnt think that the top bothered me but 15 years later it finally got hte better of me so went to the orthodontist and asked could he sort them and he said yes so i asked how much and it is costing me 400 pounds but he did give me an expander which has made the room for them to move but now he wants to put a fixed brace ojn which i didnt want as im a 35 year old guy and dont want to look stupid

i dont htink he is going to charge me extra as he said that that was what he iss charging for the treatment and it isnt going as he thought but he did say that it would be better to use the fixed brace even though the removable brace he made me has the springs on it to push the teeth straight
where in the uk are you as you could try my guy but i think you really need to know what you are gonna pay before you start treatment
good luck hope you get it sorted
