Evaluation by B Matthews of OAU, for Care UK Community Partnership, of a redevelopment site on the edge of the town centre. A probable garden soil, containing 19th century pottery, sealed the natural. The only earlier evidence were two areas of disturbance in the natural, interpreted as tree root holes, one of which contained a sherd of probably 16th century Border Ware.

Excavation and a watching brief by D Hopkinson of AOC, for Countryside Properties (Commercial) PLC, of the site of Phase 5 of the Chertsey Revitalisation Scheme, following an evaluation in 1997. The earliest evidence revealed was a series of intercutting Saxo-Norman gullies, apparently demarcating an enclosure extending to the north and west, with an opening in its south east corner. A series of pits and ditches of 14th - mid 16th century date appear to be the next phase of activity. Two major ditches of this date defined plots alongside Guildford Street.

Excavation, watching brief, and historic building recording programme, by Charlotte Matthews of Wessex, on behalf of Scottish Widows Fund and Life Assurance Company, prior to redevelopment. Features dating from the 12th to 18th/19th centuries were revealed, although nothing from the late medieval to early post medieval was found. Virtually no structural remains survived; it is likely that prior to the 18th century the area investigated lay in yard areas to the rear of the street frontage buildings.

A watching brief was maintained by G Hayman and M Dover of SCAU on works for a new store building within the area of Oatlands Palace, for the Girl Guides Association. Within the new foundation trenches the remains of a culvert associated with the infilling of the moat during Henry VIII’s reign was identified. A second feature expected, a wall identified during earlier excavation, was not seen.

Dendrochronological dating by M Bridge of EH to assist the ongoing work on the building and contribute to a reconsideration of its listed grading. The building contains a room with post-Dissolution paintings (317, 321), and a single timber in that room gave a likely felling period of AD1485--1517, slightly earlier than had been previously assumed for the wall on stylistic grounds.

Evaluation by J Stevenson of SCAU in advance of a residential development revealed no features of archaeological significance. Residual 16th century pottery was recovered from modern layers, indicating that archaeological remains may be present in the area, possibly at levels that will not be compromised during the proposed construction works.

Evaluation by Geoff Potter of CA involving the excavation of six trenches. Two sherds of 11th or 12th century Medieval pottery were recovered from two ditch features in the southern part of the site, and a small fragment of 16th century decorated stove-tile (possibly from the nearby site of Oatlands Palace) in a trench to the north. The ditch features are believed to be early boundary or drainage cuts or shallow water cut channels within an agricultural landscape; and a number of narrow Post-Medieval drainage cuts observed illustrate continued farming of the site.

The fourth season of excavation by D G Bird for SCC and SyAS completed the plan of the 16th century brick building — a rectangle c 4 by 3 metres — and further examined the medieval ditches, whose purpose and plan remained unclear. (175)

Excavation and watching brief undertaken by R Brown of OA in advance of the creation of a swimming pool and related amenities revealed mostly modern deposits, but a rectilinear arrangement of postholes may represent the remains of a simple timber building of possible 16th–17th century date. This may have been a temporary storage or lodging structure associated with the construction of the manor-house or the domestic functions of the west wing. A Kelly of OA also undertook some historic building recording work before and during alterations to Sutton Place
