DIY chain Wickes is cutting 100 jobs at its head office in Hertfordshire.
The company says it's part of a cost-cutting drive at its Watford base to make it "leaner and more agile".
The parent company, Travis Perkins, has pointed out weakness in the DIY market, and low consumer confidence.
A spokesperson told Retail Gazette: "In order to continue to drive growth for our business, we have been re-shaping our support centre to allow us to be leaner and more agile, and focus on key areas of growth in our multi-channel/digital businesses.
The new structure will result in the reduction of approximately 100 out of 7,000 roles in the business".
