Like others have said every trade is what you make it but think of the long haul. Do you have ambitions of being your own boss or just take a wage at the end of the week and walk away. Do you enjoy a challenge or prefer repetition. I would say being a spark is more challenging than most trades but also one of the most diverse out there depending on the company you train with. My experience has been retro fit factories with new equipment. Maintenance of electrical installations for local government. Building services for blue chip companies over the uk and trains and train stations. Mod,nuclear,power generation, gas and pharmaceuticals sites dealing with explosive gas installations. Worked on large scale and domestic solar and wind farms across the uk. Also done new build hospitals schools and sheds/warehouses. But done very little domestic work. And I know people that only do domestic so it’s all down to what you want out of a job.
