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

Evaluation by L Loe of OA comprising two trenches to inform the design of an extension on the south side of the church. Within the first trench, five inhumation burials were revealed with associated coffin fittings of the post-medieval period. The second trench revealed a further five inhumation burials, but these had no associated post-medieval coffin fittings and are thought to date to the medieval period. A linear cut feature pre-dating the burials was also revealed in this trench.

Watching brief by M Sims of OA did not reveal any finds or features of archaeological interest, and no continuation of the deposits recorded during the 2003 excavation of the Glyn House site was observed

Evaluation by E Glass of OA beginning in 2004 in advance of residential development. This has revealed evidence for concentrations of mainly Late Iron Age to Early Roman activity, with the potential for at least one settlement of Iron Age date existing in the areas examined. A low-density spread of features was encountered throughout much of the large area examined, suggesting landscape exploitation from the Iron Age through to the post-medieval period.

Geophysical survey and evaluation by D Sykes of OA to inform a bid to the Heritage Lottery Fund for the restoration and enhancement of the park landscape. The geophysical work provided generally disappointing and inconclusive results, especially around the area of the priory where it had been hoped that evidence for former monastic structures would be forthcoming, although magnetometry work on the summit of Park Hill did reveal a number of anomalies consistent with the presence of a Bronze Age site that is suspected to exist in the area.

Evaluation in two phases by W Bedford of OA prior to commercial redevelopment. No finds or features of archaeological interest were revealed in phase 1 investigations. Phase 2 works have yet to be undertaken

Evaluation by A Ainsworth of OA in advance of redevelopment revealed a number of tree throw hollows, and an undated ditch.

Historic building investigation by J Phimester of OA prior to modernisation of the weir structure revealed that parts dating from the original construction in 1887 still exist, although they have been subject to some modification.

Phase I of a large-scale evaluation by A Ford of OA prior to the submission of a planning application for residential development. A small number of worked flints were recovered, suggestive of low-level early prehistoric activity in the general vicinity. Of more significance was evidence of a Late Iron Age to 1st century Roman settlement, with indications that an intensification of activity might have occurred towards the end of this period.

Watching brief by D Dodds of OA during the erection of equestrian and agricultural buildings revealed no finds or features of archaeological interest.
