Airx Jet Support Limited & Anor v London Jet centre (Stanstead) Limited & Anor

Facts

The claimants, AirX Jet Support Limited and AirX Charter Limited, operate a private jet airline and charter business from the east half of a large hangar at Stansted Airport. The defendants, London Jet Centre (Stanstead) Limited and Diamond Hangar Limited, are in common ownership. The claimants say they are tenants or alternatively licensees, and that the defendants as landlords or licensors must keep the roof in repair and supply heating. The defendants dispute the scope of those obligations, though they admit an implied term that the premises be reasonably fit for purpose, which in principle extends to roof repair and adequate heating. The claimants alleged serious roof leaks and a failure to switch on the gas heating, and said regulatory approval was at risk. They applied on 15 April 2025 for interim mandatory injunctions requiring roof repairs and the supply of heating. Mr Andrew de Mestre KC, sitting as a Deputy High Court Judge, heard the application on 19 September 2025 and handed down judgment on 14 October 2025. By an order dated 8 December 2025 he granted a best-endeavours heating injunction. He found a serious issue to be tried on the roof and that damages were not an adequate remedy, but was not satisfied on the balance of convenience without better evidence of the roof's condition. He directed expert evidence and adjourned the roof application, which came before Judge Carter on 23 July 2026.
