Lawsons Timber, Building and Fencing Supplies are celebrating raising over £50,000 for charity.
The company was founded by the great grandfather of current chairman Simon Lawson in 1921.
Last year the family run business marked its 90th year of trading and to celebrate reaching the milestone, the company organised a number of fundraising events in aid of Macmillan Cancer Support.
Charity events were held across their branches in London and included a dart tournament, directors leg waxing, charity golf day and charity auctions.
There were also eating challenges and moustache shaving, as well as charity fun days in all branches.
Managing Director Joe Inzani said: "We are absolutely delighted with the final figure raised for Macmillan. We were really well supported by the staff, customers and suppliers alike.
"The final figure not only exceeded all our expectations but was also the largest single corporation donation received by Macmillan in the region all year."
