Gas installations

A gas installation comprises the piping, fittings and appliances downstream of the point of supply, which may be a distribution system or a cylinder supply.

The Gas (Safety and Measurement) Regulations 2010 (the Regulations) came into force on 4 May 2010. The Regulations define the point of supply for the Gas Act 1992, and the Plumbers Gasfitters and Drainlayers Act 2006.

The definition of point of supply is used in:

  • The Plumbers, Gasfitters and Drainlayers Act 2006, where it is applied to the meaning of gasfitting. Where LPG is supplied from a cylinder, this has the effect of moving the point where gasfitting begins to the outlet of LPG cylinders, from a former position at the outlet of first stage pressure regulators.
  • The Gas Act definition of gas distribution system.
  • The Regulations in relation to requirements for odorisation, gas specification and gas pressure.
