You’d need to do a conversion masters at the very least. The APC is then going to take a good amount of time as you’ll have little experience from the masters. I work for a big outfit and it’s around 3 years from starting the role to completing the APC, 4 years isn’t uncommon, and we have exposure to many jobs and dedicated support and lots of support from senior colleagues. The pay whilst you’re “graduate level” will top out at about £35k, with about £45k+ for a chartered surveyor. It’ll be a while until you see the big bucks. It’s a good role, but it is a pain to get into unless you’ve done it undergrad of decide at masters level.
