Anti-social behaviour in leasehold properties can take many forms, but few are as serious or as disruptive as drug-related activity or immoral conduct. These issues not only affect the well-being of residents but can also carry legal and reputational risks for landlords and managing agents. This article outlines practical steps leaseholders can take when faced with such concerns.

Recognising the Signs

Common indicators of drug-related or immoral activity may include:

• Frequent short visits at odd hours
• Strong odours or chemical smells
• Excessive noise or aggressive behaviour
• Suspicious packaging or paraphernalia

If you suspect such activity, do not confront the individuals involved. Your safety is paramount.

Step 1: Report to the Police

The first and most important step is to report your concerns to the police. Under the Misuse of Drugs Act 1971, it is a criminal offence for a landlord to knowingly permit drug production, supply, or use on their premises. Police have the authority to issue a Closure Notice, sealing the property for 3–6 months if it is associated with serious nuisance or disorder.

Step 2: Notify the Managing Agent or Freeholder

Once the police have been informed, contact your managing agent or freeholder. Provide:

• A summary of your concerns
• Any police reference numbers
• Dates and times of incidents

Managing agents can then take steps to notify the leaseholder (if the issue involves a sub-tenant) and may initiate lease enforcement procedures.

Step 3: Understand Lease Obligations

Most leases include clauses prohibiting illegal or immoral use of the property. For example:
“Not to use or suffer the Property to be used for any illegal or immoral purpose (note: unauthorised possession of controlled drugs is considered illegal for the purpose of this clause).”
If breached, the landlord may have grounds to seek forfeiture or other legal remedies.

Step 4: Consider Acceptable Behaviour Agreements

Local authorities may use Acceptable Behaviour Agreements (ABAs) to address early signs of anti-social conduct, particularly among younger residents. These voluntary agreements can be effective in curbing problematic behaviour before it escalates.

Step 5: Legal and Insurance Considerations

Landlords and managing agents should be aware of their responsibilities:

• Failure to act on known illegal activity can result in fines, imprisonment, or property forfeiture
• Insurance policies may require regular inspections and tenant vetting to remain valid in the event of drug-related damage

Final Thoughts

Drugs and immoral behaviour are serious issues that require swift, coordinated action. Leaseholders play a vital role in identifying and reporting concerns, while managing agents and landlords must act decisively to uphold the law and protect the community.
