The group, which specialises in selling outdoor clothing and equipment, saw online sales jump during the period 21.6%, and also reported a bumper Black Friday, which was its busiest day on record with sales of over £2.5m.
The company said it served over three million customers during the 13-week festive period, with “bestsellers” including over 500,000 pairs of socks, over a million winter jackets and around a million winter hats, gloves and scarves.
Mountain Warehouse, which started with a single store in December 1997, now has almost 400 stores in nine counties and plans to open around 50 new stores in 2020, creating over 600 jobs.
Founder and CEO, Mark Neale, said: “I’m delighted to be reporting record Christmas trading for the 22nd year running, despite the snap election and some economic uncertainties around Brexit.
“It demonstrates the success of our bricks and clicks strategy and proves the doom-mongers predicting the death of the high street are wrong.”
He added: “If you have the right locations customers will come and if you have the rights products at the right price and also provide great service they will part with their hard-earned money.
“This puts us well on course for another record year and, as a result, we are continuing to invest in more stores, new territories and our online business.”
