Householders/tenants on the impacted part of the Keele gas network can refuse consent for gas appliance safety checks.
All evidence collected from laboratory tests and house/buildings checks will be presented to the Health & Safety Executive. They will decide based on this available evidence whether to approve a blended gas for delivery.
If they do approve a blend of hydrogen/natural gas, the gas will be considered to be compliant gas and can be delivered to the homes on the network in the same way normal gas is delivered today. The Phase 1 safety checks will make sure gas appliances and systems currently connected to the network are safe and ready for a trial.
