Harworth Estates was established in 2004 as the property division of UK Coal, named after the location of its headquarters in the village of Harworth in Nottinghamshire.
Following a restructuring in December 2012, UK Coal became Coalfield Resources plc. The new company owned 24.9% of Harworth Estates, with the remaining 75.1% owned by UK Coal's pension trustees, and later transferred to the Pension Protection Fund.
In March 2015, Coalfield Resources bought the remaining 75.1% of Harworth Estates from the Pension Protection Fund for £150 million. The acquisition was financed through a mixture of issuing new shares to the Pension Protection Fund and raising money though a public offering. It was renamed Harworth Group plc and was listed on the London Stock Exchange.
In March 2018, Alastair Lyons joined the business as Chairman. In November 2020, Lynda Shillaw was appointed Chief Executive.
As of 2023, the Pension Protection Fund retained a 23% holding in the business. The Peel Group owned a further 14% through its subsidiary, Goodweather Investment Management.
In September 2026, the Peel Group secured over 50% of the company's shares at a cost of £630 million. Then, in October 2026, the Peel Group increased its holding to 75% of the companies shares, allowing it to request delisting of the company from the London Stock Exchange.
