Jeweller Theo Fennell has been acquired by its founder, backed by a division of private equity turnaround specialist Endless.

The eponymous Theo Fennell bought back his business, which has stores on London’s Fulham Road and at the Royal Exchange in the City, out of administration with the support of Endless’ Enact SME investment arm.

Fennell launched the business in 1982.

Four years ago it was bought by a consortium of investors including Jon Moulton, whose Better Capital business formerly owned Jaeger, and Nectar scheme founder Sir Keith Mills. It was put into administration last month as a search for new owners was undertaken.

Fennell said “I am thrilled by this outcome as Endless really understands this brilliant British business and its passionate team and we will be allowed to do what we have done best and successfully for 45 years – producing wonderfully designed and beautifully made jewellery and silverware, much of it bespoke or unique for people who love originality and craftsmanship.”

Garry Wilson, who led the investment for Endless, said: “Theo plans to take the business back to its roots in Fulham Road providing unique pieces for its customers. We are delighted to be working with Theo and his talented team of artisan designers and craftsmen.”

Endless’ current and recent investments include Jones Bootmaker, Arran Aromatics, The Works, and The West Cornwall Pasty Company.
