A number of finds in Great Barford date to the Anglo-Saxon period. Sadly, they are not sufficient to say whether there was continuing, unbroken, settlement from the end of Roman Britain through the period commonly referred to as the Dark Ages.

The Bedfordshire Historic Environment Record [HER] details every historic building and landscape feature in the county. Summaries of each entry are now available on-line as part of the Heritage Gateway website. Archaeological excavation produced evidence of Saxon occupation at a site north-east of Peashill Lane [HER 13358]. A ditch, a pit, a post hole, ridge and furrow marks, a nail, animal remains and slag were all found along with a pottery vessel dated to the 8th or 9th century.

An Anglo-Saxon socketed spearhead was found by a lock on the River Ouse [HER 16049]. It was made from iron and had a slender blade tapering to a fine point.
