The church is built to a two-bay plan punctuated by a small sanctuary at the east end. There is no tower, just a west bellcote and entry is through a small west porch.
The interior is very simple, with a wooden west gallery overlooking the nave. The gallery is supported on four slender posts and fronted by an attractively panelled front. There are only a pair of pews, but these and the wooden pulpit, altar, lectern, and panelling survive from the original Georgian construction.
The church fell out of use when a new All Saints was built in 1926. An annual ceremony called "Old Church Sunday" has a procession through the village, ending at the Old Church, where participants offers prayers for mariners on the River Ribble.
Becconsall Old Church is not in regular use and is cared for by the Churches Conservation Trust with the help of a local Friends group.
