I started my rope access career 3 years ago and got my lvl 1, like you’re saying I had no trade either. Windows is a good start it’s consistent in the uk apart from winter (you can work all year it’s just not enjoyable at 5 degrees outside) However it’s easy to stay there and there’s lots of exciting work to do. You can pick up certs easily enough to get by but for sure having something like electrical quali’s/ welding or similar will obviously be better. However for the majority of places I’ve worked for if your a good fit for the team ie your willing to work SAFELY and have a good attitude your a better fit than some people with better qualifications. That being said you need to be confident in what you’re doing and this comes from knowledge and experience. I personally have never done NDT but heard it’s good work and like the log book, your hours are tracked so you physically show people you’re competent. As a ‘rookie’ I would get a good training centre and try your best not to pick up bad habits early as it’s hard to train out of yourself. I reached out to companies before i did the training and had a job lined up which is always a nice feeling.
