The fly-half, 30, who is back in the national squad after a three-year absence, will leave Wasps when his contract expires this summer and Kingsholm was confirmed as his next destination on Monday.
He told Press Association Sport: “I was waiting on a possible England call-up. It definitely wasn’t expected and it happened and obviously made the decision for me to stay in England.
“That’s not to say I was definitely going to go abroad if it didn’t happen, but it was something I was looking at.
“It was a difficult position, having to keep putting clubs off, and it kept happening. So it was very timely and I’m very grateful for the call up.”
Cipriani revealed Gloucester head coach Johan Ackermann and director of rugby David Humphreys inspired his decision.
“I decided on Gloucester after meeting with David and Johan and hearing the vision they have for the squad and what they’re building there,” he said.
“It is definitely exciting and something that I feel is going to be a great challenge for next season.”
