Gavin Bourne, 47, achieved the incredible feat during the first 18 holes of the Club Championship Match Play Final at Droitwich Golf Club.
The 0.4-handicapper, who began playing golf at 13, had only previously recorded one hole-in-one while playing alongside others, when he was a junior.
Sunday saw Mr Bourne take on Tom Ainge to see who would be crowned Droitwich Golf Club Champion in a 36-hole final.
After the pair exchanged wins on the first two holes, Mr Bourne went ahead in style.
One of the aces came on the third hole, where he hit a six-iron from 175 yards.
Mr Bourne said: “We saw it land but you can’t really see the green.
“Walking up, there was a pitch mark about three foot in front of the hole, but also Tom’s ball five feet away from it.
“I said ‘Am I going to look a bit daft if I walk up to the green without my putter?’
“And we got up to the hole and there it was.”
Remarkably, he followed it up with another ace on the 15th, using a five-iron from 187 yards.
He said: “The Club Captain who was refereeing went straight up to the green to watch us tee off.
“He saw my ball go in, but he kept calm until Tom had hit his tee shot.
“All of a sudden he then appeared with his arms in the air and took a picture of the hole.
“I thought he was having me on. I couldn’t believe it.”
Mr Bourne, a plumbing and heating engineer, went on to win the final 8&6.
James Crampton, England Golf Championships director, said: “The odds of two aces in a round are estimated to be 67 million to 1, so Gavin’s achievements are astonishing – especially considering it was in a Club Championship Final!”
