Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what measurement traceability the UK uses for dispensed quantity at hydrogen refuelling stations.

Measuring equipment used for trade in hydrogen is regulated under the Weights and Measures Act 1985. It is an offence to use any measuring equipment for trade purposes which is false or unjust or to commit any fraud using it.

Each Local Authority Trading Standards Department has a legal duty to enforce the Act and to ensure it has the capacity necessary for carrying out its functions in its local area. Where required, trading standards would test fuel dispensers in use for trade using instruments whose calibration or test is traceable to the national measurement standards. The Office for Product Safety and Standards provides central advice and technical support to Local Authority Trading Standards on metrology issues.
