We will be running a 5-day NPLQ course during the Easter holidays to qualify lifeguards with a view to employing them for supervision at the pool. The pay is very generous – over £12/hr with additional holiday pay... The price of the course isn't set yet, but we only charged £150 last year – much less than other training venues. We might have to increase the price for this course

You have to be over 16 to take the qualification test and work at the pool
