BrightHouse chief executive Hamish Paton is to leave the retailer after 12 years including two at the helm.
Paton joined the rent-to-own business in 2006 and took over as chief executive from Leo McKee in September 2016.
BrightHouse credited Paton for “successfully steering the business through a period of unprecedented change” throughout the past two years.
After a turbulent period of trading, the retailer entered a £220m restructuring deal in 2017 to refinance debt.
BrightHouse was then given full authorisation by financial regulator the FCA in February 2018, following a review.
BrightHouse chair Stuart Deane said: “Hamish has played a pivotal role in the successful turnaround of BrightHouse. It has been a real pleasure to have worked with him.
“I wish him all the best in his new role and am grateful that he has agreed to stay on for the next few months to help us achieve a smooth transition. The search for his successor has started.”
Paton is leaving to take up a role at an undisclosed business.
