Our 'Getting Connected' guide has more information for domestic customers and we also have checklists for new connections, service alterations and disconnections to make sure you have all the information you need to complete your application.
To help you calculate the cost, you can get a quick cost estimate for single residential connections, service alterations or disconnections. We're unable to offer this to our business customers as there are too many variations in commercial jobs.
Before you use your new supply, you need to establish whether you have a gas supplier for your property. The Energy Networks Association (ENA) new supply leaflet tells you what you need to do.
It’s illegal for anyone to carry out any work on our network (including new connections and alterations) unless they’re suitably qualified under the Gas Industry Registration Scheme. A list of registered providers can be found on the Lloyds Register website. We’ll need to approve any third party's work in advance to make sure they
meet all our safety requirements. If
they go ahead without our approval,
we may have to cut off your gas and
bill you for any resulting repair work. You can find further details in this leaflet from the ENA.

The Wildlife and Natural Environment (Scotland) Act 2011 also requires public bodies in Scotland to provide a publicly available report every three years on the actions they’ve taken to meet this biodiversity responsibility. This report outlines the positive actions we’ll be taking to further the Act’s aims by delivering the objectives of our Environment and Sustainability policy for our stakeholders.

Gender pay reporting is a legal requirement for organisations with over 250 employees to publish details of the gap in both pay and bonuses between their male and female employees.
HR & Services Director Kate Naylor commented: “This is an important report which confirms our total commitment to ensuring no-one is put-off working at SGN because of perceived diversity or fairness issues. The ageing workforce in our sector means we face a skills gap over the next five to ten years which makes it crucial we widen our pool of candidates to include women at all levels and ensure we hang on to female talent. We’ve started to make some positive changes, but accept change will take time. We are however, committed to building a more diverse SGN and creating a culture of inclusion where everyone, regardless of difference, is valued. ”

Due to the inability to acquire sufficient interruptible capacity, no DN Interruptible Summary Reports will be published by SGN for the 2018 Annual Interruption Tender.
In accordance with Unified Network Code, Transportation Principle Document Section G (Supplies) paragraph 6.4.3, the summary report by location (SRL file) relies on there being awarded contracts for at least three (3) Users in a location to ensure a level of anonymity. As there were no contracts awarded, this criteria was not met and therefore the SRL file cannot be issued.
SGN will continue to invite tenders in future years. The next annual tender window is in June 2019.
In the meantime if you require any further assistance please contact either: Leyon Joseph on 02380 816730 or Scott Duncan on 01293 818256 or e-mail firstname.lastname@example.org.
Our long term development statement (LTDS) and demand forecasting document (DFD) provide a 10-year forecast of our gas transportation system usage and likely system developments.

For 2017 we have made the information more accessible for our stakeholders by combining the LTDS and DFD into the one publication.
