Question to the Home Office:

To ask the Secretary of State for the Home Department, what data her Department holds on the average individual cost of an evidential drink-driving test for (a) blood and (b) urine alcohol content.

The Government’s Road Safety Strategy launched in January 2026, includes a consultation on a range of motoring offences including the drink and drug driving testing framework. The government will continue to support the police to ensure they have the tools needed to keep road users safe.

The Home Office does not hold information on the annual and individual costs of evidential drink-driving tests for the police.

Total funding to police forces in 2026-27 will be up, to £18.4 billion, an increase of £796 million compared to the 2025-26 police funding settlement. It is for PCCs and Chief Constables to determine how to allocate this funding to best support operational requirements.
