Out-of-hours drainage refers to engineer response provided outside normal business hours, typically defined as weekdays before 08:00 or after 18:00, plus weekends and bank holidays. Across Greater London, premium callout charges usually apply for out-of-hours attendance reflecting standby costs and travel. Before the engineer arrives, occupants should stop using all water-using fittings, identify external manhole locations and clear access, and gather information such as property type, drainage issue and previous repairs. The service typically includes initial telephone triage, attendance within agreed response targets, immediate fix or temporary control, and a post-attendance report for insurance purposes. Buildings insurance often covers out-of-hours callouts where drainage failure causes internal damage, although policies vary on whether the standard or premium rate is covered.
