This varies from industry to industry and increases yearly.
The SOLAS website (referring to now disbanded FAS) and the Review have slightly different numbers but this could simply be due to the time difference (FAS cites allowances from 2007). I’ll present the wages suggested by the review as it is the latest document:
Year 1: 30-75% of fully qualified rate;
Year 2: 45-80% of fully qualified rate;
Year 3: 65-90% of fully qualified rate;
Year 4: 80-90% of fully qualified rate.
E.g. Engineering (£14.86 fully qualified rate):
Year 1: £4.40 (roughly 30%) an hour = (roughly) £176 a week;
Year 2: £6.60 (roughly 45%);
Year 3: £9.60 (roughly 65%);
Year 4: £11.90 (roughly 80%) an hour = (roughly) £476 a week.
For the whole duration of the training.
