Seeds you didn’t plant: how statutory implied terms could reshape your next dispute

Many commercial disputes begin with a disagreement over express terms – price, delivery or specification – but often evolve into claims founded on breaches of implied terms, particularly where the express terms are silent or ambiguous on questions of quality or performance.

These implied terms, planted by statute into contracts for the sale of goods and the supply of services, often go unnoticed at the drafting stage. But when a dispute crystallises, they can be pivotal.

Parties typically focus their negotiations on the commercial essentials: what is being supplied, when, at what price and subject to what limitations. Liability caps, exclusion clauses and indemnities receive careful attention. Yet the statutory implied terms in the Sale of Goods Act 1979 and the Supply of Goods and Services Act 1982 are rarely discussed.

Why do implied terms matter in litigation?

The implied terms on satisfactory quality, fitness for purpose and the requirement that services be carried out with reasonable care and skill impose obligations that exist independently of what the contract says. Where the express specification is met but the goods fail in use, or the service is delivered but the outcome disappoints, these implied terms can provide a cause of action that may not have been contemplated at the outset.

A claimant whose express case is weak may find that the implied terms offer firmer footing.

Satisfactory quality

Under section 14(2) of the 1979 Act, where goods are sold in the course of a business, there’s an implied term that they will be of satisfactory quality – encompassing fitness for common purposes, appearance and finish, freedom from minor defects, safety and durability.

The standard is objective: would a reasonable person regard the goods as satisfactory, having regard to any description, the price and all other relevant circumstances? This gives claimants scope to argue that goods which technically conform to a specification nonetheless fall short. Satisfactory quality is not limited to functional adequacy; it encompasses the reasonable expectations of the buyer, informed by the commercial context.

Fitness for purpose

Section 14(3) of the 1979 Act implies a term that goods are reasonably fit for any particular purpose made known to the seller. Where the buyer communicates a specific intended use, the seller assumes responsibility for the suitability of the goods. This term frequently becomes central to disputes involving bespoke or specialist goods.

If the goods aren’t fit for the communicated purpose, the seller is in breach regardless of the care taken.

Reasonable care and skill

The Supply of Goods and Services Act 1982 implies a term that the supplier will carry out the service with reasonable care and skill (section 13). Unlike the strict obligations relating to goods, this is a fault-based standard. Where the contract is silent on performance standards, section 13 fills the gap – and its application may produce results that neither party anticipated.

The interplay with exclusion clauses

In business-to-business contracts, the Unfair Contract Terms Act 1977 (UCTA) permits exclusion of liability for breach of the implied terms in sections 13 to 15 of the 1979 Act and section 13 of the 1982 Act, but only insofar as the exclusion satisfies the requirement of reasonableness.

The reasonableness assessment is fact-sensitive, featuring bargaining power, clarity of drafting, availability of insurance, pricing and market practice. An exclusion clause that seemed robust at the drafting stage may prove ineffective in litigation, leaving the implied terms in full force.

The litigation dynamic

The pattern is recognisable: the buyer alleges that goods or services failed to meet the required standard; the seller responds that liability was excluded; the buyer invokes the statutory implied terms, arguing that the exclusion clause is unreasonable.

The dispute therefore shifts from construction of express terms to the enforceability of the exclusion. Parties who assumed their express terms settled the allocation of risk may find that the implied terms have reopened it entirely.

Practical implications

Awareness of implied terms should inform both drafting and dispute strategy. At the drafting stage, parties should consider whether to disapply or modify the implied terms (to the extent permitted by UCTA) or to address quality and performance standards explicitly.

At the dispute stage, both claimants and defendants should assess the potential role of implied terms early: they may provide an alternative route to recovery or an unexpected exposure that changes the trajectory of settlement.

Conclusion

The statutory implied terms shouldn’t be afterthoughts. They are foundational obligations that shape the legal relationship between the parties, whether they were discussed at the time of contracting or not.

When a dispute arises, they frequently become the seeds from which the claim grows – seeds you didn’t plant, but which may determine the harvest.
