From the 1880s until 1980 mines extracting fuller's earth were to be found in Combe Hay.[9][10] During World War II production expanded to supply foundries and in paint production. Work was scheduled under the Essential Works Order 1941 and new equipment installed. The site was bombed on the night of 25–26 April 1942 during the Baedeker Blitz raids on Bath, causing damage to some of the machines. The next night local residents sheltered in the mine. By the end of the war production was up to 250 tins a week. By 1949 the site had been electrified, therefore the Garrett steam engine was sold and the chimney demolished. The Fuller's Earth Union was taken over by Laporte plc. In 1978 a new extension was built making granules for cat litter, but in 1979 a major customer making cars in the West Midlands closed and production was wound down until closure in 1980.[11]
The site of the former Fuller's earth works on the A367 was taken over by Bath Recycling Skips (see above image), in the distance is the Bath Odd Down Park & Ride at the end of Combe Hay Lane. Further development is planned just below this site with up to 171 new houses being developed, although with a great deal of opposition from the inhabitants of Southstoke and Combe Hay.[12]
The parish council has responsibility for local issues, including setting an annual precept (local rate) to cover the council’s operating costs and producing annual accounts for public scrutiny. The parish council evaluates local planning applications and works with the local police, district council officers, and neighbourhood watch groups on matters of crime, security, and traffic. The parish council's role also includes initiating projects for the maintenance and repair of parish facilities, such as the village hall or community centre, playing fields and playgrounds, as well as consulting with the district council on the maintenance, repair, and improvement of highways, drainage, footpaths, public transport, and street cleaning. Conservation matters (including trees and listed buildings) and environmental issues are also of interest to the council.
The Anglican parish church has a 15th-century tower but the body of the church was altered in the late 18th century and restored with the addition of a south aisle and porch in 1874, possibly by the Lord of the manor, George Smart.[15]
