Rylands v Fletcher [1868] established a rule of strict liability for escapes of dangerous things from land.

Rylands v Fletcher

Tort Law > Rylands v Fletcher

You are examining a claim involving an escape from land and you must remember that Rylands v Fletcher imposes strict liability - meaning no proof of negligence is needed - but the rule now has significant modern limitations, including foreseeability of damage and the requirement of a proprietary interest in land. SQE1 questions frequently test whether the elements are satisfied.

What Is the Rule in Rylands v Fletcher?

The rule in Rylands v Fletcher imposes strict liability on a person who brings onto their land something likely to do mischief if it escapes, and which does escape and cause damage. The defendant is liable even without proof of negligence.

The modern formulation, as refined by the House of Lords in Transco plc v Stockport Metropolitan Borough Council [2003], treats the rule as a sub-species of private nuisance. This means the claimant must have a proprietary interest in the affected land. Understanding negligence duty breach causation and remoteness provides context, and knowing private nuisance will help you see how Rylands v Fletcher relates to nuisance law.

Key Principles for SQE1

  • The classic elements (Rylands v Fletcher [1868]): (1) The defendant brings onto their land something likely to do mischief if it escapes; (2) there is a non-natural use of the land; (3) the thing escapes from the defendant's land; and (4) the escape causes foreseeable damage.

  • Non-natural use: The use must be extraordinary, special, or out of the ordinary - not something that is a common or ordinary use of the land. A domestic water supply is a natural use (Transco); storing large quantities of chemicals is a non-natural use (Cambridge Water Co v Eastern Counties Leather plc [1994]).

  • Escape: The thing must escape from the defendant's land to land where the claimant has an interest. An explosion on the defendant's own land that causes debris to fall on the claimant's land involves an escape; damage confined to the defendant's land does not (Read v J. Lyons & Co [1947]).

  • Foreseeability of damage: Following Cambridge Water, the damage must be of a type that was reasonably foreseeable. This aligns the rule with general negligence principles on remoteness.

  • Sub-species of nuisance (Transco): The claimant must have a proprietary interest in land (consistent with Hunter v Canary Wharf in private nuisance).

  • Defences: Act of God (unforeseeable natural event), act of a stranger (unforeseeable third-party intervention), statutory authority, consent of the claimant, contributory negligence of the claimant, and default of the claimant.

Exam tip

Remember: Rylands v Fletcher requires an escape from the defendant's land—confinement to the defendant's own land fails the claim. Non-natural use is the higher threshold; ordinary domestic water supply does not qualify, but industrial storage does. After Transco, the claimant must have a proprietary interest in land. After Cambridge Water, foreseeability of the damage type is required. 'Act of God' is a defence only if the natural event is unforeseeable.

How This Appears in SQE1 Questions

SQE1 questions test whether the elements of Rylands v Fletcher are satisfied - particularly non-natural use and escape. The most common trap is applying the rule where there has been no escape from the defendant's land (Read v Lyons). Questions also test whether the claimant has standing (proprietary interest required after Transco) and whether the damage was foreseeable (Cambridge Water). Watch for scenarios involving ordinary domestic use of land - this is unlikely to be 'non-natural.' This is a classic SQE1 trap.

Quick Example Scenario: A factory stores large quantities of industrial solvent in underground tanks. A crack in a tank causes the solvent to seep through the ground and contaminate a neighbouring farmer's well water. The contamination was not foreseeable at the time of storage.

This mirrors the Cambridge Water facts. The storage of industrial solvents is likely a non-natural use of land, and there has been an escape causing damage to the neighbour's land. However, if the contamination was not reasonably foreseeable at the time of storage, the claim under Rylands v Fletcher fails. Foreseeability of the type of damage is required.

Common Mistakes Students Make

  • Applying Rylands v Fletcher where there is no escape from the defendant's land - escape is an essential element (Read v Lyons).
  • Forgetting the foreseeability requirement introduced by Cambridge Water - the rule is strict, but not absolute.
  • Treating ordinary domestic use of land as 'non-natural' - the threshold for non-natural use is high (Transco).
  • Overlooking that Rylands v Fletcher is now a sub-species of nuisance - the claimant needs a proprietary interest in land.

Quick Summary

  • Rylands v Fletcher imposes strict liability for escape of a dangerous thing from land
  • Non-natural use means extraordinary or unusual use, not ordinary domestic use
  • The damage must be of a foreseeable type (Cambridge Water)
  • Defences include act of God, act of a stranger, statutory authority, consent, and claimant's default
  • The rule has been significantly narrowed by Transco v Stockport

Quick check questions based on this article.

Question 1

Scenario

A landowner stores large quantities of water in a reservoir on his property for irrigation purposes. The reservoir was constructed by a reputable engineering firm and has been in use for three years without incident. Following exceptionally heavy rainfall, the reservoir overflows and water floods onto a neighbouring farmer's land. The flood water destroys the farmer's crop of wheat, causing significant financial loss. The landowner had no knowledge that the reservoir might overflow. The neighbouring farmer had previously asked the landowner to install an overflow pipe, but the landowner considered it unnecessary. The farmer brings a claim under the rule in Rylands v Fletcher.

Which of the following elements is the farmer most likely to have difficulty establishing in a claim under the rule in Rylands v Fletcher?

Question 2

Scenario

A landowner constructs a large ornamental pond on her property, lining it with a synthetic membrane and filling it with water. The pond is situated at the top of a gentle slope, with a neighbouring property located downhill. The landowner hires a reputable landscaping company to design and construct the pond. After an unusually heavy rainstorm, which the Met Office describes as a once-in-50-years event, the synthetic membrane ruptures. A large volume of water escapes from the pond and floods the neighbouring property, causing significant damage to the neighbour's garden and ground floor. The neighbour had recently installed expensive flooring throughout the ground floor. An expert report confirms that the membrane was properly installed but was not designed to withstand the water pressure created by the exceptional rainfall. The landowner had obtained planning permission for the pond. The neighbouring property is also in a residential area. The neighbour had not taken out insurance against flood damage. The neighbour brings a claim under the rule in Rylands v Fletcher.

Which of the following is the most likely outcome of the neighbour's claim?

Question 3

Scenario

A manufacturer operates a factory on a large industrial estate. The factory stores significant quantities of a volatile chemical compound used in its production process. The compound is kept in pressurised containers within a purpose-built storage facility that meets all regulatory requirements. A disgruntled former employee of the factory breaks into the storage facility at night and deliberately opens the valves on several containers. The chemical compound escapes and drifts onto the land of a neighbouring business, causing extensive contamination. The neighbouring business suffers losses of £120,000 in cleanup costs and lost revenue. The former employee had been dismissed for misconduct three months earlier. The factory had installed CCTV cameras but the former employee had disabled them before entering. The neighbouring business brings a claim under the rule in Rylands v Fletcher against the manufacturer.

Which of the following is the strongest defence available to the manufacturer?
