Continuation of excavation and survey by M Russell for BSAG, in trenches near the standing gatehouse, produced archaeological evidence supporting the documentary evidence for a double courtyard house of late 15th to early 16th century date, mostly demolished in the 17th century. Excavation within and behind the gatehouse produced evidence for occupation from at least the 13th century. (206)

Report provided details of previous excavations by D J Turner. Parts of the defences were sectioned and the principal masonry building within the inner ward was examined. The original defences were a D-shaped ringwork approximately 80 x 55m within a kidney shaped outer ward or bailey. The massive ditch and bank around the inner ward were sectioned. Work on the masonry building showed that it measured-23.27 x 24.64m with square stair turrets at NW and SE corners. Internal features included possible supports for first floor hearths.

Trial excavation by G H Cole for Surrey Heath Group of SyAS of an apparent hilltop ditched enclosure noted on aerial photographs produced no evidence to explain either the marks or a positive resistivity survey. In site observation during development, Mesolithic flakes and cores, medieval and later coins and pottery were found.

Final phase of excavation by G H Cole for Surrey Heath Group of SyAS located the outfall of an early 17th century wooden water supply pipe partly excavated in 1983. It is thought to have supplied an artificial pond for watering animals. Possibly Mesolithic flint flakes, a scattering of abraded 3rd/4th century RB pottery and various 13th-14th century ditches and other features were also recorded. (212)

Excavation by R J Poulton for SCC in advance of building work. A flint scatter and a Mesolithic tranchet axe indicated prehistoric activity in the area, and RB pottery and tile suggested a nearby site, whose whereabouts were possibly identified by a resistivity survey. The excavation produced a substantial early Saxon midden deposit, with much bone and pottery, the latter of a number of different types. There were also late Saxon ditches parallel to previous discoveries, and a scatter of medieval pottery. (216)

Excavation and site watching by N Shepherd and P M G Tones for SCC, Crowngap and Royal Insurance in advance of redevelopment. The area proved to have been much disturbed in the post-medieval period, but it was possible to trace RB flood deposits in a former channel at the rear of the site, and some fragments of early RB clay and timber buildings in the centre. Finds from later disturbance indicated the former presence nearby of substantial RB buildings. Traces of a medieval timber structure were also found and the much damaged remains of a medieval stone building on the street frontage.

Excavation by P M G Jones for SCC and Courage in advance of redevelopment examined medieval river channels and an area adjacent to the Church Street frontage, where some deeper features survived destruction by recent activity. One deep linear feature had a fill of RB building debris, and a levelling layer over it contained early to mid Saxon pottery. A ditch filled in in the 1101/12th century and several 13th-14th century features were also found. (220)

Observation of redevelopment work by D W Williams showed that the petrol station had destroyed all archaeological features except the late medieval undercroft. Part of the east-west section along Slipshoe Street could be recorded, revealing at least three former surfaces of the road. The earliest contained small sherds of 16th/17th century pottery and leather including the end of a knife sheath and part of a shoe. (207)

Excavation by D W Williams on the site of buildings shown on the 1634 map. One was located although nothing was found datable to before c1750; a shallow gully with Saxo-Norman pottery was also found. (213)

Excavation by D W Williams in the partly demolished 17th century barn adjacent to the parish church. In the northern half of the excavation was a deep feature over 5m wide, probably a former watercourse, with a fill of several layers: firstly 1m of silt with a few struck flakes, then the articulated but headless remains of an ox, then silt with 11th/12th century pottery and bone, then layers of debris including a 13th century roof tile dump. All were cut by a pit or ditch roughly revetted with flint, stone and tile and having roof tile in its fill.
