Excavation of a trench across the westernmost bell barrow on Horsell Common by volunteers from SyAS under the direction of D and A Graham, with further assistance from members of the Horsell Common Preservation Society. The work, carried out in advance of footpath diversion and restoration works, highlighted that the barrow had been subject to a large number of 19th and 20th century interventions, but that much of the original structure survived intact.

Evaluation by N Brennan of WA within four areas of a proposed mineral extraction site that appeared to contain a possible 19th century mill site and a possible sub-circular enclosure. No evidence of the mill site was revealed, but the evaluation confirmed the presence of the large sub-oval enclosure on a slightly raised area of ground. The enclosure survived as a ditch, with no traces of a bank, and was identified in three of the evaluation trenches. The ditch contained a small quantity of Middle-Late Bronze Age pottery.
Soil stripping, mapping and sampling by I Howell of MOLA, continuing work that commenced in 2010. Two additional Roman-period urned cremation burials were revealed, as well as a probable Middle Bronze Age vessel, and a shallow gully of indeterminate date. Further areas investigated as part of the phase II investigations showed a lack of prehistoric or Roman activity, although some limited post-medieval evidence in the form of shallow gullies and pits was observed.
Watching brief by N Randall of SCAU during redevelopment across the hospital grounds revealed the heavily truncated remains of a large Middle Bronze Age urn, a vessel type found in both funerary and settlement contexts.
Evaluation by S Thompson of WA. A ditch containing Late Bronze Age pottery and a waterlain soil deposit characteristic of either a river channel or flood plain suggest the site is located within a well-preserved and rich prehistoric landscape.
Watching brief by T Tapply of AC revealed a small pit containing Bronze Age pottery.
Soil stripping, mapping and sample exercise by J Wright of COT revealed three features, all of which contained charcoal. Two contained oak and the third contained alder/hazel fragments, burnt at a high temperature and exhibiting evidence of probable in-situ heating/burning, and probably represent the remains of burnt tree stumps associated with woodland clearance. Radiocarbon dating of the alder/hazel suggests such clearance occurred in the Late Bronze Age or Early Iron Age.
Evaluation by A Taylor of TVAS. Two distinct clusters of pits and postholes were revealed. One cluster produced material dating to the Middle Bronze Age and included fragments of urns from the subsoil suggesting the former presence of a cremation cemetery in the area. The second cluster of features did not produce conclusive dating evidence. A third area of the site contained evidence for a more dispersed series of features, which were dated to the Early Bronze Age, Iron Age and possibly Saxon periods, as well as a series of undated linear features.
Evaluation by R Lambert of SCAU. Two tree hollows, a cluster of large postholes, and a series of colluvial deposits containing notable quantities of flintwork and pottery of Neolithic/Bronze Age date, was revealed.
Two phases of archaeological excavations were undertaken within the Tilly's Lane development area on the north side of Staines High Street. A single trench was excavated at Tilly's Lane East between April and June 1999, with two trenches at Tilly's Lane West - British Gas and High Street sites - between February and May 2000. All the trenches lay on the gravel island, though Tilly's Lane East and the British Gas site lay within early flood zones.
