Mike Fillis of "Cult Times" magazine considers "Big Ben Strikes Again" to be a highlight of the series, describing the episode's scale model work as "superb". Writing for "What DVD" magazine, Gary Russell cites the episode's opening act, which he says revolves around Macey's "paranoia", as an example of "Captain Scarlet"s relative maturity for a children's series as well as its "sense of darkness ... and real drama". Chris Bentley, author of "Captain Scarlet: The Vault", describes Scarlet and Blue's race to the construction site as "fostering unbearable tension", which he believes to be heightened by Spectrum's defeat in the previous episode.
