While the Avocet was not built in numbers, one of the prototypes was used as a seaplane trainer for the Royal Air Force's (RAF) High Speed Flight.

[1] It was a single-engined, all-metal biplane, powered by a 230 hp Armstrong Siddeley Lynx engine, having interchangeable wheels and floats.

Although it did not have folding wings, it was designed to be easily dismantled for storage on board ship.

[1] Both prototypes were evaluated for the Fleet Air Arm at RAF Martlesham Heath, where, owing to the low-powered engine, their performance was seen to be unimpressive,[2] and it was not ordered into production.

Although no production occurred, the second prototype was used by the RAF's High Speed Flight at Calshot as a seaplane trainer for Schneider Trophy pilots.
