In 2001 the company ventured into manufacturing, acquiring Bellbird producing custom-made curtains, blinds, and accessories, with the facility now being known as Dunelm’s Manufacturing Centre. On reaching their 50th store (Walsall) Dunelm opened a new warehouse in Burton.

In September 2020, the company reported a large surge in sales for the months of July and August. The increased sales were a result of people working from home as a result of the COVID-19 pandemic and investing in their living spaces.

In November 2020, the company was criticised by shareholders for renominating Paula Vennells to its board, despite her responsibility for the Post Office subpostmasters’ scandal, during which her leadership was accused of having been “both cruel and incompetent” by a Conservative peer and various MPs. Her resignation from the board was announced on the morning of 26 April 2021 after all the remaining convictions of subpostmasters had been quashed.
