On returning to London, Pomeroy joined the Art Workers Guild in 1887, and in 1888 began exhibiting with the Arts and Crafts Exhibition Society. In 1887 he was part of a group of artists, supported by the Royal Doulton Company, who created sculptures for a fountain in honour of Queen Victoria in Glasgow. For the fountain, now situated on Glasgow Green, Pomeroy carved the group representing "Australia". Also in 1887 he met the architect J. D. Sedding who subsequently commissioned a large number of decorative architectural works from Pomeroy. These included carvings for the Church of Our Most Holy Redeemer in London, an exterior sculpture for the tower of St Clement's Church in Bournemouth plus a screen and choir stalls in bronze for Holy Trinity, Sloane Street.
