Burnham had been at Uinsure since it was first launched in 2007.
He says: “I really enjoyed my time in Uinsure which was a fantastic business which I’m sure it will do extremely well in the future.
“But I’m now focussing my attention on growing the ARs and advisers within Intrinsic.”
Burnham is also one of 25 individuals at Intrinsic who are set to take part in 300 KM bike ride along the Sierra Nevada Mountains near Granada in Southern Spain.
The group will be raising money for the Intrinsic Foundation charity Childrens Hospices UK.
