Why does everyone assume they can fast track any trade that normally takes a 4 year apprenticeship ?
All the company owners I know and me included will not touch these 'boil in the bag' tradesmen. Don't tell you that on the course do they, the reason there is a shortage is because no one can be arsed with the apprenticeships anymore

But I would recommend appliance testing, boring as hell but a one day course and a £900 tester gets you out there, £200 a day is common doing that
I have enough bikes thanks
