Indemnity vs Warranty In UK Contracts: Key Differences

If you’re negotiating a new supplier contract, SaaS agreement or client T&Cs, you’ll almost certainly run into the terms “indemnity” and “warranty”. They both sit in the risk and liability section of a contract - but they do very different things.

Getting this wrong can expose your business to uncapped claims, disputes and insurance issues. The good news? With a clear understanding of indemnity vs warranty under UK law, you can allocate risks fairly, negotiate confidently and protect your business from day one.

In this guide, we’ll break down the differences, when to use each, how they interact with caps and exclusions, and practical drafting tips for UK SMEs.

What Is The Difference Between An Indemnity And A Warranty?

At a high level:

• A warranty is a contractual promise that certain facts are true or that a standard will be met. If it’s untrue or breached, the remedy is typically a claim for damages under normal contract principles (you must prove loss, causation and remoteness; you also must mitigate).
• An indemnity is a promise to reimburse specific losses on a pound-for-pound basis if a stated risk occurs. It’s generally designed to cover defined loss types and can bypass some of the hurdles of a standard damages claim.

In other words, warranties speak to “truth and standards”, while indemnities are about “reimbursement for specified risks”.

How Claims Differ In Practice

• Burden and measurement of loss: Warranty claims usually require you to prove the breach caused your loss and that the loss wasn’t too remote. Indemnities can provide a more straightforward recovery mechanism by specifying the losses that will be reimbursed (for example, third‑party claims, legal costs or regulatory fines).
• Duty to mitigate: For warranty claims, the injured party must take reasonable steps to reduce loss. An indemnity may expressly disapply or modify mitigation obligations (though courts may still interpret the clause narrowly).
• Types of loss: Indemnities often capture third‑party liabilities (like IP infringement claims brought against your business), while warranties commonly cover “state of the world” promises (for example, that software does not contain malicious code, or goods meet specification).

Why This Matters For UK SMEs

Because indemnities can shift financial risk in a more direct way, they’re frequently negotiated and limited. Warranties typically sit alongside performance obligations and service levels. Knowing which is which helps you avoid agreeing to an indemnity where a simple warranty would do - or relying on a warranty where you really need robust indemnity protection.

When Should A UK Small Business Use An Indemnity?

Use an indemnity when a specific risk could cause you losses beyond your immediate control, especially where third parties are involved. Common examples include:

• Intellectual property: The supplier indemnifies you for third‑party claims alleging the supplied software, content or branding infringes IP rights.
• Data protection: A processor indemnifies a controller for fines, claims and costs resulting from the processor’s breach of data protection obligations (noting that some fines are not legally insurable and drafting must be careful).
• Third‑party claims generally: A contractor indemnifies you for personal injury or property damage caused by their negligence while on your site.
• Tax and employment status: A contractor indemnifies you for HMRC liabilities flowing from their misclassification or failure to pay tax.

Where you do use indemnities, be deliberate. Consider whether you need only a third‑party indemnity (claims brought by others), a first‑party indemnity (your direct losses), or both. Spell out the categories of covered losses (for example, settlement sums approved by the indemnifier, reasonable legal fees, expert costs).

It’s also good practice to line up indemnities with your insurance. If you’re asked to give a broad indemnity, check whether your public liability, professional indemnity or cyber policy will respond.

Indemnity vs Warranty: A Quick Scenario

Imagine you’re a retailer licensing product images from an agency. If the agency warrants they own the images, you can sue for breach if that turns out to be false - but you’ll need to prove your loss. With an IP indemnity, the agency reimburses your defence costs and any settlement for third‑party copyright claims. The indemnity provides more direct protection for the exact risk you face.

How Warranties Work In Practice (And Your Consumer Law Obligations)

Warranties set expectations of quality, performance and compliance. In B2B contracts, they can confirm things like:

• Goods are as described and free from defects for a defined period.
• Services will be performed with reasonable care and skill (mirroring the common law standard).
• No viruses, backdoors or open‑source licence conflicts in delivered software.
• Compliance with applicable laws (for example, data protection, health and safety).

They’re usually paired with remedies like repair, replacement or re‑performance, sometimes within a defined warranty period. For customer‑facing businesses, a documented process helps - many businesses implement a clear Warranties Against Defects Policy to standardise how warranty issues are handled.

Consumer Law Still Applies

If you sell to consumers, the Consumer Rights Act 2015 (CRA) implies non‑excludable rights, including that goods must be of satisfactory quality and fit for purpose, and services must be provided with reasonable care and skill. Any attempt to limit those rights is likely unenforceable. Your contract should complement, not contradict, those statutory guarantees. Our overview of warranty claims and “not fit for purpose” explains how these rules play out in day‑to‑day operations.

For B2B deals, the Unfair Contract Terms Act 1977 (UCTA) may still subject exclusions and limitations to a “reasonableness” test. So even if two businesses contract together, you can’t always exclude everything. Reasonableness will look at factors like bargaining power, availability of insurance and clarity of the clause.

Where Warranties Sit In Your Contract Suite

It’s common to build warranties into your standard terms, whether you sell tangible products (for example, through Sale of Goods Terms) or service packages (typically within a Goods & Services Agreement). Clear drafting here can reduce disputes and set customer expectations from the outset.

How Do Indemnities And Warranties Interact With Limitation Of Liability?

Limitation and exclusion clauses are the brakes that keep your overall risk at a manageable level. The challenge is how those caps and exclusions apply to indemnity obligations versus warranty claims.

Key Points To Consider

• Do your caps apply to indemnified amounts? Some contracts expressly carve indemnities out of the cap (uncapped indemnities), while others include indemnities within the overall cap. Either approach can be reasonable if tailored to the risk profile.
• Are certain loss types excluded? Exclusions for “loss of profit”, “indirect or consequential loss” and similar categories often appear. Decide whether those exclusions should apply to indemnified losses or be disapplied for specific indemnities (for example, IP infringement).
• Non‑excludable liabilities: You cannot exclude liability for death or personal injury caused by negligence, fraud, or certain statutory liabilities. These sit outside any negotiated cap by law.
• Reasonableness: Under UCTA, caps in B2B contracts must be reasonable in all the circumstances. A carefully calibrated cap is more likely to hold up than a blanket exclusion.

Don’t Forget Insurance And Flow‑Downs

If you give customers a strong indemnity, you’ll want your suppliers or subcontractors to provide a back‑to‑back indemnity to you, and to carry appropriate insurance. Align the contract risk allocation with your cover limits wherever possible.

Drafting Tips: Clauses To Include And Common Pitfalls

Getting the drafting right is half the battle. Here’s a practical checklist when you’re next reviewing a contract.

For Indemnities

• Define the trigger precisely: “arising out of X” can be vague. Consider “to the extent caused by the indemnifier’s breach, negligence or wilful misconduct” if you want a fault‑based trigger.
• Specify what’s covered: Include (or exclude) settlements, court awards, interest, penalties, reasonable legal costs, and internal management time if relevant.
• Control the defence: Add a “conduct of claims” process - prompt notice, cooperation, who chooses lawyers, who controls settlement, consent not to be unreasonably withheld. This prevents runaway legal spend.
• Apply an appropriate cap: Decide whether the indemnity is subject to the general cap, a higher sub‑cap (for example, 200% of fees), or uncapped for carefully chosen risks like IP infringement.
• Exclude double recovery: Make clear that you can’t recover the same loss under both an indemnity and damages.
• Exclude where insurance already responds: Sometimes you’ll specify that recovery is net of insurance proceeds (pro and con here - get tailored advice).

For Warranties

• Be clear and measurable: “Industry‑leading” is hard to prove. “Conforms to the specification in Schedule 1” is much easier.
• Set warranty periods and remedies: State the time window and precise remedy (repair, replacement, re‑performance). If you want remedies to be exclusive, say so expressly (subject to UK law).
• Include knowledge and materiality qualifiers where appropriate: For example, “so far as the supplier is aware” and “no material defect” - but don’t over‑qualify or you’ll hollow out protection.
• Avoid conflicts with statutory rights: Particularly if you sell to consumers. Your wording must work alongside CRA protections.

Clauses That Support Both

• Notices and time limits: Reasonable notice periods for claims help both sides plan and gather evidence.
• Mitigation: If you want indemnities to include a duty to mitigate, say so; otherwise, set practical cooperation obligations.
• Severability and blue‑pencilling: If a court trims an over‑broad clause, you want the rest to survive. This matters if a particular indemnity carve‑out is challenged as unreasonable under UCTA.

Common Pitfalls To Avoid

• Uncapped, open‑ended indemnities: Agreeing to “indemnify for all losses arising in connection with the agreement” is risky. Tie indemnities to specific, foreseeable risks.
• Hidden carve‑outs: Watch for exclusions that silently switch off protection (for example, a global exclusion of “loss of profits” that undermines your indemnity). Our guide on onerous contract terms explains how to spot these.
• Misaligned flow‑downs: If your customer expects an IP indemnity, but your upstream supplier only gives a narrow warranty, you’re exposed in the middle.
• DIY templates: Generic clauses rarely match your actual risk profile. Professionally drafted Goods & Services Agreements and Sale of Goods Terms can be tailored to your business model and insurance.

When A Deed Makes Sense

Some risk allocations sit outside your everyday trading terms. For example, founders or parent companies sometimes give comfort to a customer via a guarantee or back‑to‑back indemnity. In those cases, a standalone Deed of Guarantee and Indemnity may be the right vehicle - the “deed” format can avoid issues with consideration and carries different limitation periods.

Amending Legacy Contracts

If you discover that a key contract uses warranties where an indemnity would be more appropriate (or vice versa), you don’t have to start from scratch. A targeted update using an addendum or variation can realign the risk profile. Our step‑by‑step guide to amending contracts covers how to do this cleanly and enforceably.

Practical Examples: Which Clause Fits Which Risk?

Example 1: Software Vendor Supplying B2B SaaS

Best practice is to include an IP infringement indemnity in favour of the customer, covering defence costs and settlement (with supplier control of defence). Performance promises (uptime, response times) sit as warranties and service levels, with credits as the remedy. The limitation of liability would cap most liabilities at a multiple of fees, with the IP indemnity either included in the cap with a higher sub‑cap, or carved out if justified by the risk and insurance.

Example 2: Trades Business Providing On‑Site Services

Include an indemnity for third‑party personal injury and property damage caused by the contractor, supported by evidence of public liability insurance. Quality of workmanship lives in warranties (for example, “work will be performed with reasonable care and skill”), often with a rectification period. Exclude indirect loss claims but keep the indemnity fit for purpose (for example, legal costs covered at standard rates).

Example 3: Product Manufacturer Selling To Retailers

Warranties cover conformity to specification and freedom from defects for a defined period, with repair/replace remedies. Include an indemnity for third‑party product liability claims arising from manufacturing defects (subject to reasonable controls). Align with your product liability insurance and ensure any upstream supplier contracts include matching protections.

Example 4: Marketing Agency Using Licensed Content

Secure an indemnity from the licensor for third‑party IP claims against your client deliverables. Add warranties that content is original or properly licensed. Flow this protection down to your client agreement so you can pass through the indemnity benefit and meet client expectations.

Key Takeaways

• Warranties are promises about facts or standards, with damages as the remedy; indemnities are reimbursement obligations for defined risks, often aimed at third‑party claims.
• Use indemnities for targeted risks like IP claims, third‑party injury/property damage, data breaches (with care) and tax/worker status - and draft triggers, covered losses and claim control processes clearly.
• Consumer law still applies: if you sell to consumers, CRA rights can’t be contracted out of. In B2B contracts, UCTA reasonableness can still bite on exclusions and caps.
• Decide how indemnities interact with your limitation of liability. Be explicit about caps, exclusions and carve‑outs, and align everything with your insurance cover.
• Watch for over‑broad or hidden risk transfers. Avoid uncapped, open‑ended indemnities and ensure flow‑down protection across your supply chain.
• Put the right protections into your standard contracts - tailored Goods & Services Agreements and Sale of Goods Terms make negotiations smoother and reduce disputes.
• If a legacy agreement needs fixing, use a targeted variation - our guide to amending contracts explains the process.
