Watching brief by A Monk of SyAS (undertaken in 2006 and since reported) during church extension and alteration works. Fragmentary evidence for the earlier medieval church was noted, although this was not extensive, and the rebuilding works of 1840–6 appear to have largely removed or buried the medieval building

Historic landscape survey by P Jones of SCAU, undertaken as part of the SCC/SyAS ASHLV assessment project. A number of features and potential areas of interest were recorded, including a possible Mesolithic flint-knapping scatter, a number of lime kilns and pond bays. Accompanying assessment of the tithe maps also provided place-name evidence for a number of potential kiln sites.

Watching brief by T Howe of SCC, on behalf of Surrey Police, following the discovery of human remains at the site during refurbishment works. The partial remains of two individuals were recovered. Although evidence for post-inhumation disturbance was clear as the remains were commingled within an obvious later feature, no firm dating evidence was noted. It was apparent, however, that the remains were of an archaeological nature rather than of interest to the police. It was thought that they may have been burials displaced during the construction of the property and reburied at the time.

Watching brief by D Platt of TVAS revealed no finds or features of archaeological interest.

Watching brief by D Whittaker of ASE revealed no finds or features of archaeological interest

Watching brief by D Graham of SyAS during refurbishment works. The site falls immediately inside the projected course of the medieval town ditch, with groundworks proposed in the area that may once have been the location for the postulated associated internal bank. No finds or features of archaeological interest were revealed.

Watching brief and resistivity survey by D Graham of SyAS during topsoil removal to create additional car parking spaces. The site lies outside the area of the former (now filled in) inner bailey ditch, and no features were detected. A number of finds were recovered during the topsoil removal, however, including a number of musket and pistol balls, and three powder caps from gunpowder flasks. An incursion of parliamentary forces into the castle courtyard occurred on 26 November 1642, with the royalist garrison surrendering as a result.

Evaluation by B Whitehead of SoAS revealed only modern features, although a single unstratified broken flint blade was recovered. SoAS

Watching brief by R Lambert of SCAU, following evaluation in 2006. No features of archaeological significance were recorded, but a number of worked flints of probable Bronze Age date, together with pottery and clay pipe stems of late 17th–early 18th century origin, were recovered.

Large-scale evaluation programme by A Manning of WA. Varied results were recorded, ranging from largely negative areas where no finds or features of archaeological interest were revealed, through to evidence for Neolithic activity, Bronze Age and Iron Age settlement, and post-medieval agricultural land management. Subsequent excavation revealed a significant number of pits, postholes and gullies of Late Bronze Age–Early Iron Age date.
