Watching brief by M Broomfield of SyAS did not reveal any finds or features of archaeological interest, although the intrusive groundworks carried out ultimately proved to be particularly small-scale.

Watching brief by R Savage of SyAS during a stoppage on the Wey Navigation. Evidence for the construction of a partition or weir between the large mill pond and the Navigation was revealed. The brick and timber construction of the weir incorporated rectangular blocks of waste from copper processing and may date from Alexander Raby’s ownership of the site between c 1777 and 1807 when he maintained an iron and copper works here. Metalworking continued at the adjacent mill until 1831, so the construction of the weir could relate to later works.

Watching brief by H Knight of MOLA, forming part of the project ongoing at this site since 2002 (SyAC 90, 91, 94 and 95), examined the western foreshore remodelling near, but not directly adjacent to, the south of Chertsey Bridge. Truncated deposits of 16th–19th century date were noted, but no evidence was revealed of the medieval Chertsey Bridge structure – presumed to have been located very close to the north of the site. No significant finds or features of earlier date were apparent.

Watching brief by K Johnson of CA revealed alluvial silt sealing successive layers of demolition material associated with the dismantling of the abbey. No in-situ structural remains were encountered in an investigation that by design did not proceed through the complete sequence of deposits in some areas. However, a number of noteworthy finds were recorded, including twelve inlaid medieval tiles from the nationally significant Chertsey tilery, and a coin of 1603, which suggests that the demolition process on the site continued for some time following the Dissolution.

Watching brief by J Lander for EH during fishpond excavations did not reveal any finds or features of archaeological significance.

Magnetometer survey by D Calow of SyAS with members of Addlestone Historical Society to locate possible pottery kilns, revealed a magnetic anomaly that may indicate the presence of a feature of archaeological interest. (418)

Evaluation by M Trevarthen of WA revealed a small group of pits containing Middle Bronze Age pottery, one example of which, a large bucket-shaped vessel, was found upright in a very small feature and might have been placed deliberately. Elsewhere, a small number of Romano-British period urned cremation burials were revealed, as well as some undated linear features. A second phase of evaluation by V Tsamis of WA revealed some narrow-gauge railway tracks probably relating to the former use of the site as a quarry, together with further undated ditches similar to those previously seen.

Evaluation by J Perry of SutAS revealed a single late post-medieval boundary ditch.

Two phase evaluation by T Munnery of SCAU, prior to the construction of a new building at the Upper School and extension to the existing Coach House. A single pit of probable 13th century date was discovered at the Coach House site. Two late medieval or early post-medieval pits were revealed at the Upper School site, with indications of earlier activity in the immediate vicinity being noted within the finds assemblage. The Coach House development was calculated not to damage archaeological horizons, so no further work was recommended.

Evaluation by M Dinwiddy of WA prior to the excavation of a lake. A single post-medieval ditch, aligned with the western edge of a tree-lined avenue thought to have been created in the 18th century and known from cartographic evidence, was encountered.
