Geophysical survey by J English of SyAS, involving a magnetometry scan of the inner precinct area, did not provide any evidence for buried structures, although a number of anomalies that may represent kilns were recorded. An historic building recording survey of the gatehouse was also carried out, and a watching brief was undertaken during remedial works, with soil displaced by animal burrowing dry-sieved for material before the burrows were infilled. A small amount of predominantly Iron Age and medieval pottery was recovered. (419

Watching brief by J McNicoll-Norbury of TVAS during stripping for a soil storage area. The truncated remains of a Bronze Age pottery vessel – possibly a placed deposit – were revealed, together with a small ditch that contained medieval pottery. See TVAS monograph 11

Watching brief during 2007 and 2008 by D Brooks of Bourne Hall Museum during refurbishment of the presumed 16th century building. The building was recorded by the DBRG as it was stripped back and its 16th century origin confirmed. The excavation of a trench for new footings within the building revealed a layer of burnt timber containing pottery of late medieval date over a mortar/chalk floor or surface, suggestive of the presence of an earlier building on the site, which had been destroyed by fire.

Evaluation by N Randall of SCAU revealed evidence of past disturbance associated with the former buildings that occupied the site from the late 19th to mid-20th centuries and the construction of the present houses on the site. No features of archaeological interest were revealed, but three medieval pottery sherds were recovered from the backfill of a modern drain.

Evaluation by P Jones of SCAU prior to an extension to the hotel. Roman structural evidence had previously been recorded on the site during archaeological observations in 1982. No repetition of this evidence was noted, although a fluvial clay was recorded at the base of the sequence, which apparently corresponded to a layer previously observed. This was overlain by a pebbly soil of medieval date with post-medieval rubble layers above, suggesting that some horizontal truncation of parts of the site had occurred

Evaluation by R Poulton of SCAU prior to building works located within the Scheduled area of the former Chertsey Abbey. Wall foundations probably relating to the Frater and Dorter ranges of the former abbey were revealed, although of principal note was the large extent of post-medieval disturbance revealed, indicating that significant damage to the medieval structures had taken place during the post-Dissolution period.

Evaluation by P Jones of SCAU revealed a considerable layer of post-medieval made-ground, with some residual medieval pottery also present. However, no excavation was undertaken through this deposit.

Evaluation by P Jones of SCAU prior to works to the car park undertaken as part of the Priory Park regeneration project revealed a substantial robbed wall foundation of uncertain date, together with a medieval feature.

Watching brief by D Williams of SCAU during the excavation of service trenches associated with the Priory Park regeneration project. Stone-built foundations, which were probably the remains of a former wing of the house, were revealed. A somewhat larger foundation that may have once formed part of the original Augustinian priory buildings was revealed, although dating evidence was not found. Four inhumation burials were also uncovered. All the archaeological remains have been preserved in situ.

Evaluation by F Raymond of BAS identified significant Bronze Age deposits concentrated on a plateau of land in the south-eastern part of the site, and this area was subsequently excavated. Activity commenced during the Mesolithic period, and is marked by the presence of a flint scatter from the southern part of the site. There were no concentrations of flint and no features, suggesting the principal focus, if there is one, lies or lay to the south and east. The focus of Early and Middle Bronze Age activity was located on the eastern side of the site.
