Legal Case Brief
Photo Production Ltd v Securicor Transport Ltd [1980] AC 827
Due diligence, negligence and exclusion clauses in contracts
Facts
Photo Production Ltd and Securicor had a contract for the provision of security services by the latter to the former. One Securicor’s staff, Mr Musgrove, decided to warm himself while providing these security services on Photo Production’s premises, and he did so by starting a fire. The fire spread and burned down Photo Production’s factory, causing them damage amounting to £615,000. Photo Production sued Securicor, who however defended by pointing to an exclusion clause in the contract which stated that Securicor would “under no circumstances be responsible for any injurious act or default by any employee. . . unless such act or default could have been foreseen and avoided by the exercise of due diligence on the part of [Securicor].” On those grounds, Securicor asserted that they were not liable for the damage caused. Photo Production in turn asserted that Mr Musgrove’s actions as agent of Securicor constituted a fundamental breach of the contract, and therefore invalidated it along with the exclusion clause. In the Court of Appeal it was held that similarly to Karsales (Harrow) Ltd. v Wallis, [1956] 1 WLR 936, [1956] 2 All ER 866, the doctrine of fundamental breach did apply in this case and that Securicor was therefore liable. Securicor appealed to the House of Lords.
Issues
The issue in this case was whether the doctrine of fundamental breach applied and was relevant, and whether an exclusion clause could be effective on the facts of this case.
Decision/Outcome
The House of Lords held that the doctrine of fundamental breach was not relevant here, and that the case was a matter of construction of the contract. The exclusion clause did on the facts, cover the damage in question and therefore Securicor were not liable for the damage.

This case brief remains legally accurate. Photo Production Ltd v Securicor Transport Ltd [1980] AC 827 is a foundational House of Lords authority and its core holding — that the doctrine of fundamental breach is not a rule of law but a matter of contractual construction — continues to represent good law in England and Wales.
The position established in Photo Production was subsequently reinforced and built upon by the Unfair Contract Terms Act 1977 (UCTA 1977), which was already in force at the time of the decision (though not applicable on the facts, as the contract was a business-to-business agreement entered before the Act’s full relevance was tested here). UCTA 1977 remains the principal statutory control on exclusion clauses in business contracts, and readers should be aware that any modern assessment of an exclusion clause must take that Act — and, where applicable, the Consumer Rights Act 2015 for consumer contracts — into account alongside the common law principles affirmed in this case. The 2015 Act replaced the consumer-facing provisions of UCTA and the Unfair Terms in Consumer Contracts Regulations 1999 for consumer contracts, but does not affect the principles applicable to the commercial contract at issue in Photo Production.
No subsequent legislation or appellate decision has overruled or materially qualified the ratio of this case. It remains a leading authority on exclusion clauses and fundamental breach and is regularly cited in UK courts.
