On 15 December 2018, an electrical fault caused a fire to break out at the Monsoon Forest Habitat. The zoo had to be evacuated and was closed. Fifteen fire crews attended the zoo along with two rapid response units and an ambulance. All mammals were accounted for and one person was treated for the effects of smoke inhalation. Some birds, frogs, fish and small insects were killed in the blaze. The zoo reopened on Sunday 16 December 2018. Chester Zoo monorail was an internal transport system for visitors from 1991 to 2019, but was closed as it had become unreliable and covered less than half the zoo due of the zoo's expansion to over .

Chester's catering facilities include Bembé Kitchen near the main entrance which opened in 2006. June's Pavilion is on the west of the zoo and Manado Street Kitchen is found on Sulawesi in the
