Evaluation by C Barton of LP. No finds or features pre-dating the 18th century were revealed, although evidence for ground-raising was noted that might have resulted in preservation at greater depths.

Watching brief by E Jeffry of CA. Despite the work taking place within the area of the Chertsey Abbey Scheduled Monument, no finds or features of archaeological significance were revealed due to the limited nature of the groundworks being undertaken. A standing wall was also recorded prior to its demolition as part of this exercise, parts of which were concluded to have been constructed from re-used abbey building materials.

Evaluation by C Edwards of AOC. A buried soil layer was examined that contained a small quantity of post-medieval pottery and a clay pipe fragment, but no features of archaeological significance were revealed.

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.

Evaluation by C Russel of ASE revealed that the site had been previously stripped and levelled almost certainly during construction of the works, and no finds or features of archaeological interest were discovered.

Evaluation by D and G Trimble of APS. A ditch was revealed that contained a significant quantity of Middle-Late Iron Age pottery. Further features found included additional ditches and a pit, all of which contained burnt flint and evidence for ironworking in the form of furnace lining, slag and hammerscale - both flake and spheroidal. The results are highly suggestive of an Iron Age domestic settlement site with associated metalworking being present in the vicinity, which, if confirmed by more extensive investigations, could potentially be of regional significance.

In February 2017 Cotswold Archaeology (CA) carried out an archaeological watching brief for CgMs on behalf of Crest and Aviva Investors at Trumps Farm, Chertsey, Surrey (centred on NGR: SU 9876 6537; Fig. 1). The watching brief was undertaken to fulfil a condition attached to a planning consent for the development of a small car park adjacent to Kitsmead Lane (Planning ref: RU.13/0857). No features or deposits of archaeological interest were observed during groundworks and, despite visual scanning of spoil, no artefactual material pre-dating the modern period was recovered.

An archaeological evaluation was undertaken on the land of the Scheduled Ancient Monument of Chertsey Abbey (SAM 23002). A total of 48 metres was excavated across five trenches. Four pits, possibly post holes, of uncertain date were identified to the southeast of the site. A possible Saxon feature was uncovered which may be part of a linear boundary ditch running west to east across the site. A possible medieval boundary was identified to the north of the possible Saxon ditch and is believed to run parallel though this could not be confirmed.
