The Jubilee line night tube will reopen in May, after being suspended two years ago owing to the pandemic.
From Saturday 21 May, the Jubilee line will run throughout the night and early hours on weekends (i.e. Friday and Saturday nights). It will join night tube services already running on the Central and Victoria lines, as well as a night Overground service between Highbury & Islington and New Cross Gate.
That still leaves some of the pre-pandemic night tube operations to reopen; TfL says the Northern and Piccadilly lines will join the others later this summer.

There were strong calls for TfL to fully reintroduce the night tube network last October, in the wake of the murder of Sarah Everard. TfL says a combination of under-resourcing and planned engineering means a more piecemeal approach has been necessary. Says a spokesperson:
The full introduction of night tube services has not been possible so far as training still needs to take place to address resourcing issues on the Northern and Piccadilly lines. The return of these lines also has to be planned around complex vital operational and engineering closures. This includes the ongoing closure of the Bank branch of the Northern line to allow completion of the upgrade at Bank tube station, as well as other major closures and bespoke timetables.
Anyone who's been on a night tube since they reopened will know they're certainly getting used.
