20 members from Barratt and David Wilson Homes Yorkshire West tackled the challenge, raising more than £3,000 for their charity of the year, Zarach.
The charity, founded in Leeds, aims to end child bed poverty across the UK.
Gavin Birch, managing director at Barratt and David Wilson Homes Yorkshire West, said: “I am so proud of our team who took part in this tough challenge for a good cause.
“We are delighted to continue our support for Zarach, our charity of the year.
“The work that Zarach carries out to end child bed poverty across the UK is admirable and we’re extremely grateful to have the opportunity to fundraise for such a worthwhile cause.”
The Yorkshire Three Peaks Challenge covers a 24-mile route and includes ascents of Pen-y-Ghent, Whernside, and Ingleborough.
Rachael Winder, business and corporate partnerships manager at Zarach, said: “It’s fantastic to have the support of Barratt and David Wilson Homes on our mission to end child bed poverty.
“Our partnership will make a lasting impact on vulnerable children who would otherwise spend another night sleeping on the floor, or in makeshift beds.”
