Jones, who plays Detective Inspector Joseph Chandler, told This Morning's Phillip Schofield and Holly Willoughby that the fourth series has been everyone's favourite to make.
The show sees his character's team investigate a series of bizarre and macabre murders in London's East End.
"When it started it was not meant to be a series, it was a one-off standalone three part drama," he said.
But he said that the creators had resolved the difficulty of having so many murders in Whitechapel with a supernatural aspect.
"Is it the devil? What's happening? Is somebody whispering in people's ears? They've opened the world up now and they can have as many killings as they like and as many serial killers as they like," Jones explained.
But the Londoner admitted an episode had scared him so much he "had to go and check all the doors and windows in the house".
"I thought the one with the guy in the walls was the scariest. That frightened me," he said.
"It's never happened to me before and I feel embarrassed saying it. I can't believe I am saying it on live television," he confessed.
"But yeah, it got to me."
Jones also explained that a plot line involving 'feral pigs' in this week's episode was actually based on a rumour in Victorian times that the animals lived in the sewers.
"They sometimes got into eating human flesh and there was this idea that there was a beasty down in the sewers," he commented.
Jones said that he was happy that this time he didn't have lots of costume changes in the show.
"Normally I would have three suits and four different kinds of shirts, and the only thing I have (to change) in this series is the tie," he said.
"I got so sick of having to go in between scenes and change, I'd change clothes sometimes ten times a day. It drove me mad, so let's just have a white shirt, the same suit and then I could get a really nice suit as well."
The actor admitted that although he had similar traits to DI Chandler, since doing the show his own obsessions have got worse.
"I enjoy doing it in the show, and so I started doing it (in real life)," Jones added. "I'm not a tidy freak, I just like everything in order."
Whitechapel is on UTV on Wednesday at 9pm.
