Cameron is now a qualified electrician who works for JS Hardie after completing his studies at Borders College in Galashiels.
The 21-year-old said: “I was really surprised when I found out I’d won this award.
"I definitely didn’t expect it and it’s made all the hard work and sleepless nights worthwhile!
“I really enjoy my job. I do mainly domestic and agricultural work as well as the occasional new-build – it’s always different and I like the challenge and variation.
“I probably enjoy rewires and new builds the most – seeing something progress from an empty building to a functional house.
"Seeing them develop makes me feel proud and it’s very rewarding to see it from cables being run to a proper, finished house. I also enjoy wiring fuse boards as well and take pride in making them as neat as I can.”
David Hardie, director at JS Hardie, said: “Cammy’s a worthy winner of this award. He picks things up well, isn’t scared to ask when he doesn’t know something and his knowledge of the regulations is brilliant – in fact he keeps me right!
“As well as being very knowledgeable, he’s also very particular – everything’s always very neat and tidy. He’s also very conscientious and all the customers who have worked with him say he’s a good worker. I’m sure he’s got a great future ahead of him and that he’ll do well whatever he decides to do.”
