Quick cost estimate tool
Are you a residential customer looking for a quick estimate? Use these links for new connections, service alterations and disconnections.
We're unable to offer quick cost estimate to our business customers as there are so many variations in commercial jobs.
Residential connections guides
Our 'Getting Connected' guide has more information for domestic customers.
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.
