Transco plc v Stockport MBC [2003] UKHL 61

Transco’s gas main ran in a council embankment. A fractured water pipe supplying council flats saturated landfill, collapsing the embankment and endangering the main. The House of Lords preserved but narrowed Rylands v Fletcher and held the council’s ordinary water supply created no strict liability.

Facts

The respondent council owned Hollow End Towers, an 11-storey block of 66 flats on the Brinnington Estate, and nearby land including a disused railway embankment. Transco (successor to the North Western Gas Board) owned a 16-inch high-pressure steel gas main laid in 1966 beneath the surface of the old railway, running through the embankment pursuant to an easement.

Water for the flats was supplied from the statutory undertaker’s main via a 3-inch internal diameter asbestos cement pipe (a considerably larger pipe than the usual domestic ¾ inch pipe, but typical and not unusual for such a block). The pipe led to basement storage tanks, from which water was pumped to roof tanks serving all flats.

In the summer of 1992 the council’s supply pipe fractured, probably because of subsidence in an underlying landfill site. The leak went undetected for some time. Large quantities of water escaped, saturating the old landfill between the tower and the embankment. On 28 September 1992, part of the embankment collapsed, leaving a 27-metre section of Transco’s high-pressure gas main unsupported and exposed, creating a serious risk of fracture.

Transco promptly undertook remedial works to restore support and cover for the gas main at an agreed cost of about £93,681. It sought to recover this cost from the council. Negligence in relation to the pipe fracture was not alleged, and a pleaded negligence case regarding blocked drains and culverts failed at trial and was not pursued on appeal.

Issues

The main issues were:

• Whether the council was strictly liable under the rule in Rylands v Fletcher for the damage caused by the escape of water from its supply pipe.
• Whether the preconditions for Rylands v Fletcher liability were satisfied, in particular:
• whether there had been an “escape” from the defendant’s land to another tenement;
• whether the water in the supply system was a “dangerous” thing within the rule, creating an exceptionally high risk if it escaped;
• whether maintaining the water supply pipe was a “non-natural” or “special” (i.e. extraordinary and unusual) use of land; and
• whether the rule should be abolished or absorbed into negligence, as in the Australian decision in Burnie Port Authority v General Jones Pty Ltd.
• Whether the rule extends beyond protection of proprietary interests in land to personal injury or purely economic loss.

Judgment

Nature and scope of the rule in Rylands v Fletcher

All members of the Appellate Committee agreed that the rule in Rylands v Fletcher remains part of English law but is a narrow, nuisance-based ground of strict liability.

Lord Bingham described the appeal as requiring a review of “the scope and application, in modern conditions, of the rule of law laid down” in Rylands v Fletcher, and identified it as a sub-species of nuisance, a tort protecting interests in land. The House reiterated that nuisance and Rylands v Fletcher are concerned with interference by one occupier of land with another’s use or enjoyment of land.

Blackburn J’s classic formulation was set out by Lord Hoffmann:

“We think that the true rule of law is, that the person who for his own purposes brings on his lands and collects and keeps there anything likely to do mischief if it escapes, must keep it in at his peril, and, if he does not do so, is prima facie answerable for all the damage which is the natural consequence of its escape.”

Lord Cairns LC’s gloss introducing “non-natural” use was also noted. The House accepted that over time the rule had been progressively confined by case law and statute.

Key elements of liability

1. Relationship to nuisance and protected interest

Following Cambridge Water Co v Eastern Counties Leather plc and Hunter v Canary Wharf Ltd, the House reaffirmed that:

• Rylands v Fletcher is “a sub-species of nuisance” (Lord Bingham) and a “special form of nuisance” (Lord Hoffmann).
• Nuisance is directed to the protection of interests in land; accordingly, Rylands v Fletcher does not cover claims for personal injury or loss unrelated to property interests.

Lord Hoffmann noted that earlier personal injury cases under the rule were inconsistent with this modern understanding and concluded:

“It must, I think, follow that damages for personal injuries are not recoverable under the rule.”

2. Escape between tenements

It was emphasised that there must be an escape of the dangerous thing from the defendant’s land (or control) to another tenement. Lord Bingham stated that “no claim in nuisance or under the rule can arise if the events complained of take place wholly on the land of a single occupier. There must, in other words, be an escape from one tenement to another.”

Lord Scott, relying on Read v J Lyons & Co Ltd, stressed that “escape” is an essential element:

“[Escape] means escape from a place where the defendant has occupation of or control over land to a place which is outside his occupation or control.”

He concluded that because the water escaped, accumulated and damaged land all owned by the council (even though subject to Transco’s easement), the strict rule was not engaged.

3. Dangerous or mischievous thing: exceptional risk

The House clarified that the thing brought or kept on the land must pose an exceptionally high risk of danger or mischief if it escapes.

Lord Bingham reviewed classic cases involving large reservoirs, explosives, enormous waste tips and industrial solvents, contrasting them with domestic water-supply cases. He held that:

“It must be shown that the defendant has done something which he recognised, or judged by the standards appropriate at the relevant place and time, he ought reasonably to have recognised, as giving rise to an exceptionally high risk of danger or mischief if there should be an escape, however unlikely an escape may have been thought to be.”

Applying this, the council’s water supply system was found not to meet the “mischief or danger” test. The pipe was a normal domestic supply arrangement (albeit scaled up for 66 dwellings), carrying water at mains pressure. The council had not “accumulated” a large mass of water, but simply arranged a standard domestic supply.

4. Non-natural (special) use of land

The House reinterpreted “non-natural” use as “ordinary” versus “extraordinary and unusual” use, judged by contemporary standards.

Lord Bingham favoured Lord Moulton’s formulation in Rickards v Lothian:

“It is not every use to which land is put that brings into play that principle. It must be some special use bringing with it increased danger to others, and must not merely be the ordinary use of the land or such a use as is proper for the general benefit of the community.”

He held that ordinary user is a preferable test, so that the rule is engaged only where the defendant’s use is “extraordinary and unusual” in its time and place. A user may be unusual without being unreasonable; the question is whether the defendant has done something “quite out of the ordinary” in context.

Lord Hoffmann agreed, noting that what counts as “natural” must be judged against modern conditions and that many once-dangerous activities are now commonplace. He suggested that a practical guide was to ask whether the damage was of a type the defendant could reasonably be expected to insure against; widespread property insurance, particularly for water damage, was relevant.

Lord Scott considered that supplying water to a residential block, pursuant to statutory housing and water duties, was plainly a “natural or ordinary” use of the council’s land. He noted the relevance of statutory obligations: where Parliament requires or authorises an activity, members of the public are expected to accept its side-effects, absent negligence.

5. Foreseeability of damage

Following Cambridge Water, the House reaffirmed that foreseeability of damage of the relevant type remains a prerequisite for recovery under both nuisance and Rylands v Fletcher. Lord Hobhouse described this as either a principle of remoteness of damage or part of the risk element, citing Lord Goff’s reliance on phrases such as “likely to do mischief” and “knows to be mischievous”.

6. Defences and statutory context

The House discussed traditional defences such as act of God and acts of third parties, treating them as aspects of causation rather than as negating strictness. Lord Hobhouse analysed authorities like Nichols v Marsland and Rickards v Lothian, emphasising that truly exceptional natural events can break the causal chain.

Considerable attention was given to the statutory landscape. Lord Bingham and Lord Hoffmann highlighted section 209 of the Water Industry Act 1991, imposing strict liability on water undertakers for escapes from their mains (subject to specified exemptions), and the assumption of strict liability in Schedule 2 to the Reservoirs Act 1975. Lord Hoffmann observed that section 209 expressly excludes liability to public gas suppliers, noting the irony that had the leak come from the statutory undertaker’s high-pressure main, Transco would have had no claim under Rylands v Fletcher and would have been excluded from the statutory regime.

Both Lord Bingham and Lord Hoffmann endorsed Lord Goff’s view in Cambridge Water that strict liability for high-risk activities is generally better imposed by Parliament, which can delineate activities and criteria precisely.

Whether to abolish the rule

The council invited the House to follow the Australian High Court in Burnie by treating the rule as absorbed into negligence. The House declined.

Lord Bingham, recognising the criticisms and the attractiveness of doctrinal simplicity, gave four reasons for refusing to abolish the rule: the justice of no-fault liability in some high-risk cases; the risk of undermining statutory assumptions; the recent reaffirmation of the rule in Cambridge Water; and the European comparative context, where neighbouring systems also recognise forms of strict neighbour liability.

Lord Hoffmann accepted that the rule was intellectually problematic and of limited practical scope, but considered abolition too radical a step for the House, particularly given its longevity and recent affirmation. Lord Hobhouse and Lord Scott similarly regarded the rule, properly understood, as a valid part of the law of private nuisance.

Instead, the House opted to retain but tightly confine the rule, emphasising its essential elements and discouraging expansive or policy-driven applications.

Application to the facts

On the key questions framed by Lord Bingham―whether the council had brought onto its land something likely to cause danger or mischief if it escaped, and whether its use was ordinary or extraordinary―the House held for the council.

Lord Bingham found that:

• While water in quantity can cause damage if it escapes, the supply pipe and tanks here were part of a routine domestic water-supply system required by statute and “would not have struck anyone as raising any special hazard”.
• The council had not accumulated a “large accumulated mass of water” comparable to a reservoir; it simply provided an adequate domestic supply.
• The use of the land for this purpose was “entirely normal and routine” and could not be characterised as extraordinary or unusual.

Lord Hoffmann added that there was no evidence the 3-inch pipe created a greater risk than normal plumbing; its larger size did not, without more, make it exceptionally hazardous. He emphasised that water-damage risks are widely and cheaply insurable and that Transco, in particular, could be expected to insure against subsidence beneath its gas mains.

Lord Hobhouse concluded that the water pipe did not itself constitute a dangerous accumulation giving rise to a Rylands v Fletcher risk. The leakage was “fortuitous” rather than the realisation of a known, exceptional risk created by the council’s user of its land.

Lord Scott, taking a more jurisdictional approach, held that the rule also failed because there was no “escape” from the defendant’s land to another tenement: the water escaped and caused damage entirely within the council’s land, albeit land burdened by Transco’s easement of support. He considered that, in principle, a servient owner is not strictly liable under Rylands v Fletcher to a dominant owner for damage to the servient land absent negligence or intentional interference.

Lord Walker agreed that the relevant accumulation was merely the water in the 3-inch pipe and that the saturation of the ground was not a deliberate accumulation of the sort contemplated by Rylands v Fletcher. He also noted that Transco’s claim had not been pleaded or argued on the basis of a “measured duty of care” arising once the danger was or should have been appreciated.

Implications

This decision clarifies and significantly limits the operation of Rylands v Fletcher in English law:

• It is firmly anchored as a narrow, property-based sub-species of nuisance, requiring a proprietary interest, an escape between tenements, a dangerous thing creating an exceptionally high risk, and an extraordinary and unusual use of land, plus foreseeability of damage.
• Personal injury claims and claims by those without a proprietary interest in land fall outside the rule.
• Domestic and ordinary service uses of land, including routine water supply for residential accommodation, are not “non-natural” for these purposes, even where scaled up for multiple dwellings.
• The House refused to abolish the rule or absorb it into negligence, but confirmed a strong preference for statutory, rather than judicial, creation of new regimes of strict liability for high-risk activities.
• Insurance and statutory regulation are recognised as important background factors: courts are reluctant to use Rylands v Fletcher to reallocate commonplace, insurable property risks between sophisticated undertakings, particularly where Parliament has already addressed related risks.

The case therefore preserves Rylands v Fletcher as a residual basis for strict liability in truly exceptional, high-risk land uses (e.g. large reservoirs, hazardous industrial chemicals), while excluding ordinary infrastructure and service uses from its ambit.

Verdict: Appeal dismissed with costs; Stockport Metropolitan Borough Council was not strictly liable under Rylands v Fletcher or in nuisance for the damage to Transco’s gas main.
