Prior to evaluation the former range of buildings in the northwestern corner of the gasworks site was thought to retain some element of a medieval building. The results of Intervention 2 demonstrate that this is now extremely unlikely and that the significance of the building is lessened. However, as part of the administrative buildings of the gasworks, the range of buildings has some significance. There are clearly substantial below-ground remains from the gasworks at the site and while not unique, either locally of nationally, they are of some significance. Furthermore, these remains may be located with some degree of accuracy since the 1850 auction map appears to be reliable.
Some contamination is clearly present at the site although the degree to which this contamination may vary across the site is not known; it is likely that it will be greater in the principal gas production areas of the former gasworks than it was in Intervention 2.
Deposits that pre date the construction of the gasworks clearly survive at the site. Significantly, where post-medieval deposits were encountered there appears to be no obvious contamination of the archaeological strata. This suggests that contaminated deposits may be perched at the gasworks use-horizon.
