What's the routine when it comes to skin cancer and and regular checkup after treatment in let's say in UK?

1)If a patient is told “You need a regular check up every year, after getting the treatment for your skin cancer”, does the hospital where she /he got the treatment not just give his/her appointment with a dermatologist, (or is it the oncologist?) automatically? If someone says I’m searching for a dermatologist for my (yearly, let’say) checkup, Would the question “Why would you need to search?” make sense?
2) And does it matter anyway whether it’s https://en.wikipedia.org/wiki/National_Health_Service_(England)
or if it’s US’s system?
