The company, which sells furnishings ranging from cushions and bedding to kitchen equipment, also reported a 16.8% fall in revenue to 236.6 million pounds ($325 million) for the 13 weeks ended March 27, 2021.
Spending on home improvement activities such as DIY (do it yourself) and furnishings has risen during the COVID-19-driven lockdowns as many people saved money and spent more on improving their surroundings while being stuck at home.
By the beginning of January 2021, all of Dunelm's 174 stores -- which are mainly at out-of-town locations -- were closed. However, the company said that its online sales made up more than 90% of sales in the third quarter.
With restrictions easing in the UK, Dunelm said it re-opened 13 stores in Scotland earlier this week, and now expects 156 stores in England and Wales to re-open on April 12.
"With all stores soon to be fully open, combined with our ... digital offering, we look forward to helping our customers to create a little more joy in their homes and gardens this summer," Chief Executive Officer Nick Wilkinson said.
Analysts on average expect annual pre-tax profit between 120 million pounds and 125 million pounds, according to a company-compiled estimate.
