Drug and Alcohol Policy (UK)

A Drug and Alcohol Policy in the United Kingdom is a legally binding written instrument.

Section 2 of the Health and Safety at Work etc. Act 1974 requires every employer to ensure, so far as is reasonably practicable, the health, safety, and welfare at work of all its employees. An employee who attends work impaired by alcohol or drugs poses a risk to themselves and colleagues, and an employer who fails to address this risk through a clear policy may be in breach of section 2. The Health and Safety Executive (HSE) has published guidance specifically on drug misuse at work, which recommends a written policy as a foundational control measure. Under the Management of Health and Safety at Work Regulations 1999, employers must carry out suitable and sufficient risk assessments that identify substance misuse as a workplace hazard where relevant. Section 7 of the Health and Safety at Work etc. Act 1974 imposes a reciprocal duty on employees to take reasonable care for their own safety and that of others affected by their actions at work — an employee who attends work under the influence of drugs or alcohol is in breach of this duty.

The Misuse of Drugs Act 1971 classifies controlled drugs into Classes A, B, and C and creates criminal offences for possession under section 5, supply under section 4, and production. Employers who knowingly permit drug use on their premises may commit an offence under section 8 of the Misuse of Drugs Act 1971. A written drug and alcohol policy, consistently enforced, reduces the risk of the employer being treated as having permitted or turned a blind eye to drug use. The Equality Act 2010 intersects with this policy area because alcohol dependency may be associated with disability (through linked physical or mental health conditions), requiring employers to consider reasonable adjustments under sections 20 and 21 before disciplining or dismissing an employee.

The Road Traffic Act 1988 creates criminal offences for driving while over the legal alcohol limit under section 5 and while impaired by drugs under section 4. Employers whose employees drive company or personal vehicles for work purposes must address these offences explicitly in their drug and alcohol policy. The drug-drive limit introduced by the Drug Driving (Specified Limits) (England and Wales) Regulations 2014 set specific blood concentration limits for seventeen controlled drugs. The UK GDPR and the Data Protection Act 2018 classify drug test results as health data — a form of special category data under Article 9 UK GDPR — requiring an explicit lawful basis and a Schedule 1 condition under the Data Protection Act 2018 before such results can be processed. The Information Commissioner's Office (ICO) employment practices guidance provides detailed advice on testing in the workplace.

A Drug and Alcohol Policy in the United Kingdom is needed by any employer who wishes to manage the legal and safety risks of substance misuse in the workplace. The policy is particularly critical for employers in safety-critical sectors — transport, construction, offshore energy, healthcare, and manufacturing — where impairment by alcohol or drugs creates a direct risk of serious injury or death. Employers in these sectors face specific regulatory obligations beyond the general duty under section 2 of the Health and Safety at Work etc. Act 1974: the Road Traffic Act 1988 makes it an offence to drive while over the legal alcohol limit or impaired by drugs, and employers whose staff drive for work must have a clear policy addressing this; the Transport and Works Act 1992 imposes strict liability offences on railway and tramway workers; the Merchant Shipping Act 1995 applies to seafarers; and Civil Aviation Authority (CAA) regulations apply to flight crew.

A written policy is also important for Employment Tribunal purposes. An employer dismissing an employee for substance misuse must show the dismissal was fair under section 98 of the Employment Rights Act 1996. An Employment Tribunal will ask whether: the employer had a clear policy stating that the conduct was prohibited; the employee was aware of the policy; the employer investigated the matter fairly in accordance with the ACAS Code of Practice on Disciplinary and Grievance Procedures; and the decision to dismiss was within the range of reasonable responses open to a reasonable employer. Without a written policy, it is very difficult to show that the employee understood the consequences of substance misuse at work.

The UK GDPR and the Data Protection Act 2018 impose significant obligations on employers who conduct drug testing. Drug test results — particularly results revealing specific health conditions or prescribed medication — are special category data under Article 9 UK GDPR, requiring explicit consent or another listed condition for processing. The Information Commissioner's Office (ICO) has published an employment practices guide addressing health monitoring, which employers should consult before introducing a testing programme. The policy should set out the basis on which testing will be conducted, the type of test used, who carries out testing, and how results are recorded and stored.

A Drug and Alcohol Policy in the United Kingdom must address the following key elements to satisfy the Health and Safety at Work etc. Act 1974, the Equality Act 2010, the UK GDPR and Data Protection Act 2018, and the ACAS Code of Practice on Disciplinary and Grievance Procedures.

Scope and purpose: The policy should explain its aims — protecting health and safety under section 2 of the Health and Safety at Work etc. Act 1974, supporting employees with dependency issues, and maintaining a safe working environment — and confirm who it applies to, including contractors, agency workers, and visitors on the employer's premises.

Prohibited conduct: The policy must define what is prohibited: attending work unfit through drink or drugs; consuming alcohol on the premises (unless explicitly permitted at company events); possessing, supplying, or producing controlled drugs under the Misuse of Drugs Act 1971 on employer premises; and driving for work over the legal drink-drive limit under section 5 of the Road Traffic Act 1988 or impaired by drugs under section 4 of that Act.

Testing procedures: Where the employer intends to conduct drug or alcohol testing, the policy must specify the circumstances in which testing may occur (pre-employment, for cause, random in safety-critical roles, post-incident), the type of test (breath, urine, saliva, hair follicle), who administers the test, and the process for confirming a positive result through a Medical Review Officer (MRO). Employees must consent to testing; for safety-critical roles, consent can be made a condition of employment. Drug test results are special category health data under Article 9 UK GDPR and require explicit consent or another listed lawful basis and a Schedule 1 condition under the Data Protection Act 2018 before processing is permitted. The Information Commissioner's Office (ICO) employment practices guidance should be consulted before implementing a testing programme.

Support and rehabilitation: The policy should set out the employer's approach to employees who self-disclose a dependency problem, including referral to occupational health, an Employee Assistance Programme (EAP), or NHS services. Employees who seek help voluntarily before a conduct issue arises are generally treated more leniently than those found to be impaired without prior disclosure. Under sections 20 and 21 of the Equality Act 2010, employers must consider reasonable adjustments before taking disciplinary action where the employee has a recognised disability associated with their dependency — for example, liver disease, anxiety, or depression arising from long-term alcohol use.

Return to work after treatment: The policy should address the conditions under which an employee may return to work following treatment for a dependency problem, including any requirement for ongoing monitoring, abstinence testing, or modified duties. A phased return to work plan supported by occupational health advice reduces the risk of relapse and demonstrates the employer's compliance with the reasonable adjustments duty under the Equality Act 2010.

Record-keeping and confidentiality: Records of tests, results, referrals, and disciplinary proceedings must be handled as confidential health information under the UK GDPR and the Data Protection Act 2018. Access should be restricted to those with a genuine need to know, and retention periods should be defined in the employer's data retention schedule.

Disciplinary consequences: The policy must specify that breaches may result in disciplinary action under the employer's disciplinary procedure, up to and including summary dismissal for gross misconduct in the most serious cases — particularly where safety is compromised or the employee drives for work. The ACAS Code of Practice on Disciplinary and Grievance Procedures must be followed, and an Employment Tribunal will consider whether the employer investigated the matter adequately, held a disciplinary hearing, and offered the right of appeal under section 10 of the Employment Relations Act 1999.
