Large UK businesses need to ensure fleet vehicles are taken into account when meeting EU energy compliance standards.

The legislation means every organisation with more than 250 staff or a turnover above GBP50m needs to assess its overall energy usage and create a plan for improvement in areas of significant consumption.

ESOS affects an estimated 10,000 businesses within the UK, who must report compliance to the Environmental Agency by 5 December, with non-compliance risking a fine of up to GBP50,000.

Cenex, which is holding a webinar on the subject on 4 July, says firms must make sure the energy used by all the vehicles in their fleet is included in their overall compliance calculations.

Organisations must cover the energy usage of fuel supplied to the company and its employees for business use, provided this is 10% or more of overall energy usage.

This means auditing the energy consumption associated with owned and leased cars, HGVs and vans, along with grey fleet vehicles.

Cenex CEO Robert Evans said: "Assessing energy usage from your fleet for ESOS compliance can seem daunting, but potentially delivers significant benefits in terms of reduced fuel consumption, greater efficiency and lower costs.

"Fleet managers need to start planning now to ensure compliance across their operations.

"Our webinar aims to provide the guidance they need to be ready for the deadline."
