When you buy a business in the UK — whether an asset purchase or a share purchase — the representations and warranties section of the sale agreement is where the seller commits to factual statements about the business and its condition. These are not just formalities: they are the primary mechanism through which a buyer can claim compensation if the business turns out to be different from what was described. Warranty claims are the most litigated aspect of UK business sales. Getting the warranties right — comprehensive in scope, properly qualified, with sensible limitations — is one of the most important parts of negotiating a business acquisition. And many buyers, particularly in smaller deals, sign agreements with warranties that are so heavily qualified they provide almost no practical protection at all.
What is a Representations and Warranties?
A representation is a statement of fact made by the seller that induces the buyer to enter the contract. If a representation is false, the buyer may have a claim in misrepresentation under the Misrepresentation Act 1967, potentially resulting in rescission or damages. A warranty is a contractual promise that the stated facts are true at completion. Breach of warranty gives the buyer a claim in contract for the difference between the value of the business as warranted and its actual value. In a UK share purchase, warranties are given about the target company — its accounts, intellectual property, contracts, employees, tax position, and litigation. Disclosure Letters limit warranties by setting out exceptions the seller has disclosed.
Red flags to watch for
If a warranty is limited to the seller's 'actual knowledge', the seller can disclaim liability for things they could have discovered with reasonable enquiry. Insist on a standard that includes 'constructive knowledge' — what they should have known.
A disclosure letter that runs to hundreds of pages, delivered 24 hours before completion, is designed to overwhelm the buyer and limit warranties. You need adequate time to review disclosures before you are bound.
The Limitation Act 1980 gives 6 years for breach of contract claims, but sale agreements routinely shorten this. Less than 18-24 months for general warranties (7 years for tax warranties) significantly limits your ability to discover and bring a claim.
Most sale agreements cap aggregate warranty liability. A cap of 10-20% of purchase price is common — a cap of 5% or lower gives you very limited recovery even for significant breaches.
A high de minimis (claims below X are ignored) combined with a basket (claims must aggregate above Y before you can claim) can effectively neutralise all but catastrophic warranty breaches.
Your legal rights
Representations in UK business sale agreements are regulated by the Misrepresentation Act 1967, which gives remedies for fraudulent, negligent, and innocent misrepresentation. The Unfair Contract Terms Act 1977 (UCTA) does not apply to most business-to-business sale agreements in the same way as consumer contracts, but any attempt to exclude liability for fraud is void. Warranty claims are governed by the Sale Agreement and the Limitation Act 1980 (6-year limitation period for contract claims, subject to contractual shortening). Warranty and Indemnity (W&I) insurance is increasingly used in UK business sales to bridge the gap between buyer and seller expectations on warranty coverage.
Questions to ask before you sign
- 1What is the knowledge qualifier on the warranties — actual, constructive, or a defined enquiry standard?
- 2When will I receive the disclosure letter, and how much time will I have to review it before completion?
- 3What is the limitation period for warranty claims, and what is the aggregate liability cap?
- 4What are the de minimis and basket thresholds, and how do they work in practice?
- 5Are there any fundamental warranties (e.g., title, capacity) that are uncapped and have the full 6-year limitation period?
- 6Have you considered Warranty and Indemnity insurance to bridge the gap on warranty coverage?
