It is available as the Mellor Strata HF 16, a step-entrance version aimed at the access bus market, so named for its maximum seated passenger capacity of sixteen;[1] or as the Mellor Strata LF, a low-floor variant targeting the service bus market, with a capacity of up to 21 seated passengers.

[2] The light and economical van-based Strata was launched to compete with the more traditional, but heavier and less economical, bus-based short wheelbase Alexander Dennis Enviro200 MMC and Optare Solo SR, as well as other van-based minibus designs, as the United Kingdom bus market was starting to go through the 'second minibus revolution' of the mid to late 2010s.

[6] East Riding of Yorkshire Council have placed the largest order for Strata HF 16s to date, taking delivery of nine examples in July 2017.

[11] Additionally, a single Strata LF has been delivered to Cheshire West and Chester Council and leased to Stagecoach Merseyside & South Lancashire for operation on the Blacon Greyhound community bus service between Blacon and the Greyhound Retail Park in Chester.

[12] The first order from a major group came in 2017, with Arriva North West taking delivery of nine Stratas for services in Macclesfield and Winsford in Cheshire.
