He was ordered off the mountain, had his passport confiscated and will be fined £17,000.
Foreigners have to pay the Nepal government $11,000 (£8,500) for permission to climb the 29,030 foot peak - a major earner for the country.Davy could be banned from Nepal for five years or face a 10-year ban on climbing in the country
Gyanendra Shresth, a government liaison officer at the mountain's southerly base camp, said: "I saw him alone near base camp so I approached him and he ran away.
"I followed him with my friend and found him hiding in a cave nearby.
"He had set up camp in an isolated place to avoid government officials.'
Ryan Sean Davy tried to dodge paying the scaling fee by running away from officials
It is highly unusual for a foreign climber to attempt to scale Everest alone - most do so with the help of at least one Sherpa guide and a large support team at base camp.
Mr Davy could be banned from Nepal for five years or face a 10-year ban on climbing in the country.
Mr Davy told officials that he did not have enough money to buy a flight from the Everest region to Kathmandu to collect his passport.
He said he would instead walk and then catch a bus - a journey that would take at least four days.
In a post on social media, Mr Davy - who identifies himself as a director and producer - said that he had reached a height of 23,000 feet metres in six hours.
He admitted: "I am going to be honest in saying that when I arrived at Base Camp it became evident that I didn't have nearly enough money for a solo permit because of hidden costs and even if I did they would have declined it because I had no previous mountaineering experience on record.Davy says he realised he did not have enough money for the climb when he got to Base Camp
"I was ashamed that I couldn't afford the permit after all the help, preparation and what everybody had done for me during my training, it would have been a total embarrassment to turn around and accept defeat because of a piece of paper.
"So I took a chance and spent the little money I had on more gear to climb and practice on the surrounding peaks for acclimatizing in preparing for a stealth entry onto Everest.
"Expedition companies have no time for wanna be Everesters with no money so someone turned me in.
"I am so sorry that I have let all my supporters down and those who had faith in me, but please believe me when I say I will find the means to finish what I started."
