• Edinburgh Old Town


    We are working in Edinburgh’s Old Town to upgrade the local gas network in the High Street, Blackfriars Street, Cowgate, Holyrood Road and St John Street.

    Following consultation with the local authority, Police Scotland, Scottish Fire and Rescue Service and local bus companies, our work started on Monday 20 March and will take approximately 28 weeks.

    Our essential work involves replacing very old metal pipework with modern plastic pipe. This will ensure a continued safe and reliable gas supply for the local community for many years to come. The modern plastic pipe has a lifespan of around 80 years.

    Our work has been planned to be carried out in phases to minimise inconvenience and keep traffic flowing. It has also been planned to ensure high profile events taking place in the area will be unaffected by our work.

    At times during the project there will be some diversions and road closures. Advance notice signage will be put in place.

    We are working 7am to 7pm, six days a week with Sunday working as and when required. We are mindful of those people who live in the area, and will aim to keep noise to a minimum.

    Our work will continue during Edinburgh Festival and Fringe, however, we will be working away from the main festival area during this time.

    Pedestrian access will be maintained at all times.

    All businesses in the local area will remain open as usual. We do have a compensation scheme in place for small businesses which suffer a genuine loss of trade because of our work. Packs are available from our website, sgn.co.uk, via the Publications section.

    All being well, our work should be completed in October.

    We are sorry about any inconvenience our work causes and would like to thank road users and residents for their patience. This is a complex engineering project, however we always aim to minimise disruption whenever possible.

    For more information such as where we are working and the diversion routes in place please see our customer leaflet.

    When we are working in historic areas such as Edinburgh’s Old Town we employ an archaeologist to observe our excavations every step of the way and ensure any features and artefacts are archeologically recorded. This is a requirement outlined by the City of Edinburgh Council’s Archeology Service (CECAS).
