UK air charter operator Zenith Aviation has ceased operations after entering administration on May 15. Paul Hargreaves of Nexus Corporate Solutions is acting as administrator and is seeking new owners for the company, which is based at London Biggin Hill Airport (EGKB).
In March 2025, Zenith was acquired by aircraft management and charter group Opul Jets, but that company—now trading as Thela Jets—ceased having control of the operation in December. Zenith operated a Bombardier Learjet 45 and a pair of Learjet 75s under its UK air operator certificate, but it does not own them.
In a written statement, Hargreaves said Zenith “is in an insolvent position due to cash flow issues, debtors not paid, and historic ownership and management issues.” He is exploring options for a possible rescue or buyout.
According to an unaudited financial statement filed with the UK’s Companies House register on March 29, Zenith had an overall loss of just over £1.9 million ($2.6 million) as of March 29, 2025. During the previous 12 months, it had recorded revenues of £14.2 million and employed 41 people.
Hargreaves told AIN that nine parties have already expressed an interest in Zenith’s assets, which are due to be valued next Tuesday. He estimated its debts at between £3 million and £5 million and said the aircraft owners are now filing to take possession of these assets.
