You can get a course for £400-£600 with a bit of searching.
Telecoms, Wind, sector seem to the largest growth currently, at least for rope access. You will need to factor in the Arqiva gateway courses, or the GWO/RUK courses alongside the offshore survival for these two sectors.
It may be possible to get regular work on the railways, inspection, geotechnical works. If you can pass a drugs test, and find a sponsor for the PTS you could be in regular work.
There are more than 100,000 registered Tech's in the world. So you need a CV that is easy to read, a skill set that is a 'must have,' and be determined.
Having said that, the work is hard but rewarding. What could be better than watching the sunrise from the top of the Shard. Or spending a few weeks on a rock face on the south coast...
