The actor, who played Beale on the soap from 1985 until 2021, had a theatre tour planned before the beginning of the coronavirus pandemic, having already scheduled a break from EastEnders.
"It's a different completely different way of life," he said. "But it suits my life where it is at the moment. And I'm quite happy doing it.
"I've seen so much of the country and I've got so much more lined up that I want to go and see."

Telling Thornton he was worried about the sound of the rain on the roof while recording, he nonetheless said the reception would be good because he was 'directly under Crystal Palace mast'.
He said that the motorhome gave him the opportunity avoid living out of a suitcase in hotel rooms, to cycle to and from his work in theatres and to have all his stuff with him.
Explaining the timeline of events, he said: "Covid came and just turned the world into what it did.
"So the tour kept getting postponed, EastEnders had already been mapped out that storyline. So we knew when I was leaving there, the tour got postponed for six months..."
He said Richie, who played Alfie Moon on the soap, always had a motorhome when out on tour with bands.
"He doesn't let anyone else drive it other than him," Woodyatt explained. "He's funny"
The actor, who was last seen in the show having been poisoned by Sharon Watts, did not rule out a return to the square, but said he hadn't asked show bosses and 'they hadn't asked him'.
He also admitted he'd told his daughter to 'clear out her room' when she moved to America because it wouldn't be there when she got back, since he enjoyed it so much after just a few days.
He told Thornton: "I said: 'I'm enjoying living in the motorhome so much, I think I'm gonna stick to it.
"And I have. It's now been 14, 15 months I've been doing it, and I absolutely love it."
But he did say he gave himself plenty of time to get used to the motorhome before embarking on his tour so he wasn't having to rush to get ready and arrive at sites 'not having a clue' what he was doing.
"It's a lot more complicated than when it was my Nan's caravan when I was seven years old," he said.
"And it was literally a bucket with a seat on it. It's a lot nicer now."
