The village is situated approximately 7 miles (11 km) north-east from Sleaford, and lies on the B1189 Walcott road near its junction with the A153.

The topography in ancient times would have been that of a small settlement on a gravel mound surrounded by marsh which was flooded in winter.

It gets its water supply from Digby Dam and Farroway Drain, two drainage channels that meet to the south-west of the village.

[7] Since November 2008 there has been an active campaign by the Billinghay Skirth Regeneration Society to restore navigation on the River Skirth, and the project has won the support of Billinghay and other parish councils, the Inland Waterways Association, the Environment Agency, Lincolnshire County Council and the Lincolnshire Waterways Partnership.

They were able to navigate most of the way, but stopped a little short of the village, due to low water levels and silting of the channel.
