SGN Gas Network - Scotland

SGN create 4 separate data layers (by pressure tier) to depict the location of their gas network:

LP - Low Pressure (19 mbar - 75 mbar)

MP - Medium Pressure (75mbar - 2 bar)

IP - Intermediate Pressure (2 bar - 7 bar)

HP - Regional High Pressure (>7 bar)

In order to assess the risk of planning applications affecting the gas infrastructure, there is a requirement to buffer the above pipe network by different distances. The Spatial Hub has provided these buffered polygons as separate data layers. These are consultation zones where SGN should be informed about relevant planning applications. Major developments with potentially widespread effects should have larger consultation distances of up to 1km: e.g. quarrying, deep mining, demolition, blasting, siting of High Voltage Infrastructure.

Current buffers: HP buffer (75m either side of pipe - 150m total)

IP buffer (25m either side of pipe - 50m total)

MP buffer (12.5m either side of pipe - 25m total)

The gas network data is up to date at the time of publication, but it is given without warranty as to the accuracy of the information shown. Service pipes, valves, siphons, sub-connections etc. are not shown but their presence should be anticipated. No liability of any kind whatsoever is accepted by SGN or its agents, servants or sub-contractors for any error or omission.

Should the user wish to excavate in the vicinity of pipelines, the User should visit SGN via sgn.co.uk/Safety/Dig-safely for further information. SGN use an on-line mapping system, accessible via the sgn.co.uk/Safety/Dig-safely web pages or linesearchbeforeudig.co.uk, this process should be used to obtain up to date maps and safety information before you excavate. However if you need more information please contact our Safety Admin team on 0800 912 1722 or by email: plantlocation@sgn.co.uk.

For the avoidance of doubt, safe digging practices, in accordance with HS (G) 47, must be used to verify and establish the actual position of mains, pipes, services and other apparatus on site before any mechanical plant is used. It is your responsibility to ensure that this information is provided to all persons (whether direct labour or contractors) working for you on or near gas apparatus.

Mains shown in the data are those owned by SGN by virtue of being a licensed Gas Transporter (GT). Gas pipes owned by other GT’s, or third parties, may also be present in the area and are not shown in the data. Information with regard to such pipes should be obtained from the relevant owners
