Kenton Cool, 48, was met by his family at Heathrow after recording the most climbs of any non-Sherpa.
Mr Cool made the 8,849-metre summit of the world’s tallest mountain at 4.30am on May 15, alongside British fitness entrepreneur Rebecca Louise, who was completing the feat for the first time.
He was greeted at Heathrow by wife Jazz and their two children – Saffron, 12, and Willoughby, nine.
The record comes despite a warning he would never walk again unaided after he shattered both heel bones in a rock-climbing accident in 1996 from which he still suffers chronic pain.
“This was after one of the most spectacular climbs I’ve had on Everest,” Mr Cool told his 51,000 followers on Instagram, alongside a picture taken among the Himalayas after completing the ascent.
“The almost full moon, glistening stars and cloudless sky provided the backdrop.
“It’s summit 16 for me, a record of sorts but really it’s not about that, it’s a celebration of team work, dedication and passion.”
Mr Cool previously became the first person to complete the Everest triple crown, scaling Everest, Lhotse and Nuptse in a single push without returning to base camp.
He was also the first British guide to lead a client to the summit of K2, the world’s second tallest mountain.
