Debenhams will consider closing up to 10 of its 176 stores under a review announced by its new chief executive, Sergio Bucher.
The department store chain, whose shares have fallen a third over the last year, said more investment is required to improve its mobile systems, supply chain and store estate.
It is also consulting on the closure of the DHL-run Lodge Farm distribution centre in Northamptonshire, which employs 220 staff and will close in two years’ time.
Ten smaller in-house warehouses will also close but Debenhams said it hoped many staff could be redeployed.
Debenhams set out the plans alongside half-year results showing a 6.4% fall in pre-tax profits to £87.8m, though UK like-for-like sales rose 0.5%.
Its shares were down 3% on the news.
Mr Bucher, who took over in October, said the overhaul would see the stores potentially closed over the next five years.
As part of his ‘Fix the Basics’ plan, around 2,000 staff will be moved to customer-facing roles, the group will axe some in-house brands and quit some international markets.
Stores will be de-cluttered with a 10% reduction in stock options and stock will be replenished faster.
Mr Bucher, a former Amazon executive, said: “Our customers are changing the way they shop and we are changing too.
“Shopping with Debenhams should be effortless, reliable and fun, whichever channel our customers use.
“We will be a destination for ‘social shopping’ with mobile the unifying platform for interacting with our customers.
“If we deliver differentiated and distinctive brands, services and experiences both online and in stores, our customers will visit us more frequently.
“And, having simplified our operations to make us more efficient, we will be able to serve them better and make better use of our resources.”
Debenhams, the country’s second-largest department store group, employs 19,000 people in its stores.
