Benchmark Log Book

The Regulations refer to a 'commissioning certificate' and indicate that the Benchmark log book is suitable for this purpose and will be available in the equipment packaging for the following product categories:

	Gas fired boilers
	Gas fired combined primary storage units (CPSU)
	Oil fired boilers (some manufacturers)
	Unvented water storage vessels

Vented storage vessels will be provided with an adhesive label attached to the vessel that will fulfil the function of a 'commissioning certificate'.

Benchmark log books have been produced in consultation with the DTLR. If the log book does not indicate this on the front cover, the manufacturer will supply the correct version.

Only manufacturing companies who hold a Benchmark licence will be eligible to use the Benchmark logo and the approved log book working and layout (Benchmark is registered as a European Collective Mark by the Central Heating Information Council Ltd. And the content is copyright).
