Evaluation by S Watson of PCA prior to use of the site as a possible extension to the existing burial ground. A likely Roman ditch and several undated, but possibly associated, postholes were revealed. Late medieval/early post-medieval pottery and ceramic building material were recovered from the subsoil, and a redeposited layer within one of the trenches is presumed to be associated with quarrying activity that map evidence illustrates took place just to the north of the trench.

Evaluation by S Wallis of TVAS at the rear of a property sometimes known as the William Mullins (one of the Pilgrim Fathers) house. The evaluation revealed a number of pits relating to domestic occupation of the site from the mid-12th century through to the 19th century. Some further work is proposed during the excavation of the service trenches, but a redesign of the proposed development to incorporate piling allows for the majority of deposits present to be preserved in situ.

Evaluation by H Rance of SLR revealed three ditches and the remains of an infilled pond. Environmental material sampled from the primary fill of the pond suggested a Saxo-Norman date for the deposit. Saxo-Norman pottery was also recovered from one of the ditches.

Two phases of archaeological excavations were undertaken within the Tilly's Lane development area on the north side of Staines High Street. A single trench was excavated at Tilly's Lane East between April and June 1999, with two trenches at Tilly's Lane West - British Gas and High Street sites - between February and May 2000. All the trenches lay on the gravel island, though Tilly's Lane East and the British Gas site lay within early flood zones.

Evaluation trenching in advance of the construction of a new road revealed prehistoric flintwork and pottery and a post-medieval gully. Two skeletons had been discovered in earlier work by S E Winbolt.

In August 2012 Oxford Archaeology (OA) carried out a field evaluation on land at Dunsfold park, Dunsfold, Surrey on behalf of Bio Group Ltd. The evaluation comprised machine excavation of 8 trenches 60m long and 2 trenches 25m in length, all with a width of 1.6m. The evaluation found very little in the way of significant archaeological remains. Agricultural furrows were identified crossing the site, generally from west-north-west to east-south-east, but the only archaeological features were one pit (or tree-throw hole) and a north-south ditch that was located crossing two trenches.

Oxford Archaeology undertook a staged programme of archaeological work at Priory Park, Reigate, Surrey, during May-July 2005 on behalf of Reigate and Banstead Borough Council and Land Use Consultants. This programme included a desk-based assessment, walkover survey, geophysical survey and trenched evaluation. Most of the fieldwork was targeted at elucidating the location and layout of the medieval Reigate Priory, and the post-Dissolution development of the Priory as a residence set in landscaped parkland.

Oxford Archaeology South (OAS) was commissioned by Andrew Josephs Ltd, on behalf of J and J Franks Ltd, to undertake an archaeological evaluation of land at Mercers Farm, near Nutfield, Surrey (centred on TQ 3050 5200) ahead of proposed mineral extraction. The work was undertaken between 3rd - 27th January 2012. A total of 94 trenches were excavated across the site. Evidence was found for activity from three main periods: the earliest spanning the late Bronze Age to early Iron Age; medieval agricultural use; and post-medieval activity.

Although no significant archaeological remains were identified during the preliminary Phase 1 watching brief works the Phase 2 works partially exposed two articulated skeletons which were preserved in-situ. The works also revealed two brick culverts. The investigation of the straw and organic material in the roof structure was of interest. The straw appears to have been used as a packing material rather than being traces of a former thatched roof and its use in this way appears to be very unusual.
