sled, nope, you're about 5 years and 10 tonnes out.
It used to be 3,000 hours, 1500 hours of that in command of a/c 30 tonnes or over in primarily international or similar operations. Then you'd be eligible for the UK ATPL etc.(The exact wording of the qualification isn't correct but you'll get the idea).
Now it's EASA so tough.
14 exams, the medical, and then there's the flying. I haven't checked that but assuming you have 500 hours in an aircraft with a sim in the UK, you'd need to do an LST observed by a CAA examiner.
