This new work draws together all the UK law, practice and regulation relating to the onshore gas industry, together with relevant EU materials. It combines practical commentary with relevant source materials. This is an essential text for all involved in UK gas law. The only work to provide comprehensive coverage of all the law applicable to the gas supply industry in the UK. Explanatory narrative - addressing topics unique to this sector and explaining complex source materials. Practical checklists; guidance on how to, for example, challenge terms of the Network Code, or a decision of the Regulator. EU coverage - essential given the political pressures to create a single market for energy and the committment to trans-European networks.
