Phillips' death in 1897 led to a decline at the pottery.
Many of the potters left shortly afterwards, including Collard who worked briefly for Hart and Moist Pottery in Exeter, then at Longpark Pottery in Torquay, and then founded the Crown Dorset Art Pottery in Poole, Dorset in 1905.
He later bought the Honiton Pottery which continued in production until the 1990s.

On Phillips's death, Aller Vale was acquired by Hexter, Humpherson & Co., a Kingsteignton-based company that manufactured tiles and sanitary fittings.
In 1901 they also acquired the Watcombe Pottery in Torquay and amalgamated the two companies as the "Royal Aller Vale & Watcombe Pottery Company".
This company, with its name sometimes simplified to "Royal Watcombe" continued working until 1962, mostly creating motto ware for the tourist market.

Work at the Aller Vale Pottery site ceased in about 1924, and the site is now occupied by a small estate of offices and light business units, surrounded by houses.
