Utilities works under 8 St Leonards Road

I would be very grateful if you could let me know when utility pipes under the pavement adjacent to No 6 were laid and to what specification

Utility services records held by Devon County Council start in 2004, therefore, this information is not held.

Guidance on the current specification of positioning and colour coding of underground utility cables can be found on page 7  of the NJUG (National Joint Utilities Group)
