The Right Mortgage and Protection Network climbed Snowdon (pictured) on Saturday, raising £3000 for Macmillan Cancer Support.
A 19-strong team from the network’s head office made it to the summit, breaking their target of £1,500.
The event was part of the business’s regular charity events schedule, which has included a British bake off competition.
Adam Stretton, managing director at the network, said: “Over the last few years several members staff have been helped and supported by the Macmillan Nurses and so it’s a charity close to our hearts.
“All of our members have been incredibly supportive and generous in their donations to both this challenge and the other fund raising events we hold.”
