Lay mains off site and onsite up to 2 (7 bar) bar for adoption by Gas Transporters and Independent Gas Transporters
Install off site reinforcement if requested by Gas Transporter
Lay services for adoption by Gas Transporters and Independent Gas Transporters (including services direct to existing mains with no associated mainlaying)
Install Pressure Reduction units
Connections up to 2 bar ( hopefully from 8 November 2017)
Install U6 gas meters ( for specified Gas Transporters)
Cut off Services ( any diameter as long as classified by GT as a service on a record)
Alter services ( excluding meter relocation and outlet )
Potential issue is that if the service is part or wholly steel then the alter will have to become a relay. National Grid will make a contribution to the relay cost based on their contractor’s rate – but it will be less than our additional costs as we will need Section 50 notice etc. Therefore alters should be subject to site survey.
