The Liability Landscape

Liability for portable toilet provision at events can fall on several parties: the event organiser, the hire company, the landowner, and in some circumstances the local authority. Understanding how liability is distributed — and ensuring it is properly insured — is essential for everyone involved.

The primary legal frameworks are the Occupiers' Liability Act 1957 (which governs the duty of care owed by occupiers to lawful visitors), the Occupiers' Liability Act 1984 (which extends a more limited duty to trespassers), and the common law of negligence. The Consumer Protection Act 1987 may be relevant where defective equipment causes injury.

The Occupier's Duty of Care

Under the Occupiers' Liability Act 1957, the occupier of premises owes a common duty of care to lawful visitors. At an event, the occupier is typically either the landowner, the event organiser, or both — depending on the terms of any licence or agreement between them.

The duty includes taking reasonable care to ensure that the premises — including all equipment on them — are reasonably safe for their intended purpose. A portable toilet unit that is:

  • Positioned on unstable ground and tips over, injuring a user
  • Inadequately maintained, creating a slip hazard from spilled liquid inside or outside the unit
  • Sited in a position that creates a trip hazard (from hoses, steps, or uneven ground)
  • Allowed to become unusable and forces users to use improvised arrangements in unsuitable locations

...is a potential source of liability for the occupier.

The Hire Company's Liability

A portable toilet hire company owes a duty of care both in the products it supplies and in any services (delivery, installation, servicing) that it performs. Where a unit is defective — a faulty latch that fails to hold the door closed, a step that collapses under normal use, a tank seal that leaks — the hire company may be liable under negligence or the Consumer Protection Act 1987.

The hire company's contract with the event organiser will typically include terms that seek to limit or exclude liability for certain matters. These exclusion clauses are subject to the Unfair Contract Terms Act 1977 and the Consumer Rights Act 2015. An exclusion clause that purports to exclude liability for personal injury caused by negligence is void under the 1977 Act.

Hire companies should carry:

  • Public liability insurance (minimum £5 million, often higher for commercial operators)
  • Products liability insurance
  • Employers' liability insurance (a legal requirement under the Employers' Liability (Compulsory Insurance) Act 1969)

Organisers should ask for sight of the hire company's insurance certificates before the event and confirm that the level of cover is appropriate.

The Event Organiser's Insurance Requirements

Event organisers need their own insurance, which should include:

Public liability insurance: This covers the organiser's liability to members of the public who suffer injury or damage as a result of the event. The level of cover required will depend on the scale of the event and the conditions attached to any licence — some local authorities specify minimum PLI levels as a licence condition. For events of a few hundred people, £5 million is a common minimum. For larger events, £10 million or more may be required.

Employers' liability insurance: Required under the Employers' Liability (Compulsory Insurance) Act 1969 wherever the organiser employs workers, including part-time and casual staff. Minimum cover is £5 million, though most policies provide significantly more.

Event cancellation insurance: Not directly related to portable toilet liability, but relevant to the overall risk management picture.

Disclosure and Policy Conditions

Insurance policies are contracts of utmost good faith. The organiser must disclose all material information to the insurer at the time of taking out the policy and at each renewal. Material information includes the nature of the event, the expected attendance, and the activities that will take place.

Policy conditions often include requirements to:

  • Comply with all relevant health and safety legislation
  • Maintain equipment in a safe condition
  • Carry out risk assessments and implement appropriate control measures

A claim arising from a toilet provision failure at an event where the organiser had not complied with their licence conditions, had not carried out a risk assessment, or had not maintained welfare provision in a serviceable state may be refused on the grounds of breach of condition or non-disclosure. Insurers investigate the circumstances of claims, and welfare failures often reveal a broader pattern of inadequate safety management.

Contractual Allocation of Liability

The contract between the event organiser and the hire company is the primary mechanism for allocating responsibility for what happens on site. A well-drafted hire contract should address:

  • Responsibility for delivery, installation, and positioning of units
  • Responsibility for ongoing servicing during the event
  • The standard of care to which the hire company commits
  • What happens if units fail or become unusable
  • Respective indemnities for liability arising from each party's actions
  • Insurance requirements on both sides

Organisers who accept standard terms from hire companies without reviewing them may find that the allocation of liability is less favourable than they assumed. Legal advice on event contracts — particularly for larger events — is rarely wasted expenditure.

Claims Arising from Sanitation Failures

The most common types of claim arising from portable toilet provision failures include:

  • Slip and trip injuries at or near toilet units (the most common category)
  • Illness allegedly caused by inadequate sanitation or contaminated facilities
  • Personal injury from structural failure of a unit (rare but documented)
  • Property damage from waste spillage

Claims of illness following events are particularly difficult to manage because causation is hard to establish and deny. An event with documented, well-maintained sanitation is considerably better placed to contest such claims than one where provision was inadequate and records are absent.

Practical Recommendations

  • Obtain and retain certificates of insurance from your hire company before the event
  • Confirm your own event insurance policy covers the specific risks associated with portable toilet provision
  • Ensure your hire contract clearly allocates responsibility for installation, servicing, and ongoing maintenance
  • Document welfare provision and servicing during the event — photographs, logs, and inspection records
  • Ensure your event risk assessment addresses welfare provision and that it is available to your insurer if required
  • Comply with all licence conditions relating to sanitation, as breach of licence conditions may void cover

Insurance is not a substitute for proper provision. It is the backstop when proper provision fails despite best efforts. The event organiser who has done everything correctly will find their insurer a rather more cooperative counterpart than the one who did not.
