Across the series tattoo artists will take each other on in a host of tasks, designed to test their inking ability.
On getting onto the show and - surviving week two - the former Beaconside Primary School and Ullswater Community College pupil, said: "It was a bit overwhelming to be honest.
"It was really fun though. I've done nothing like it. It was completely new to me.
"I just didn't want to go out first. That's all I was thinking so to get through any more will just be crazy to me."
After finishing school Luke studied at Kendal Art College for a couple of years, which helped him get on an apprenticeship.
"As far as I can remember I always wanted to be a tattooist," he explained.
"I have always enjoyed art. The job is as much a hobby as it is a job. I really enjoy it.
"It's nice waking up to go to something you enjoy as a hobby as well."
Luke, who works at Samsara Custom Tattoo and lives in Grange, is so popular he's not currently able to take any more bookings - and says he's booked up for the next five years.
This year he said most of the people who've taken appointments are coming from overseas, including someone from the Carribbean.
He's currently working on a body suit for Chris Miller, from Liverpool, who travels across the world with Luke to conventions, and he has recently tattooed Gaz Beadle from the reality series Geordie Shore.
Luke specialises in black and grey realistic tattoos.
While the Japanese style isn't Luke's favourite area of tattooing, he enjoyed it and gave it his best shot in the latest installment of the show.
He said: "The whole part of the show is testing our skills in all the areas. To find someone who can do everything to a good standard.
"All the artists who applied for the show all have their own specialties but it could go in anyone's favour as to what comes first."
