New year, new caps: refresh your liability limits

A new year is a good moment to refresh your contract playbook – especially your liability limits and exclusions. These clauses decide who carries the risk when things go wrong.

A clause that’s outdated, unclear or unenforceable may fail when you most need it. This article outlines the key UK rules and simple steps to update your approach.

Why liability caps matter

Liability clauses do three jobs: set a monetary cap, decide which losses are recoverable and carve out liabilities that can’t be excluded or must stay uncapped. They also influence pricing, insurance and operations.

The law imposes guardrails, so overly aggressive or unreasonable drafting may not be enforceable.

The UK legal framework

Three pieces of legal framework help set out what you can and can’t exclude or limit:

• Unfair Contract Terms Act 1977 (UCTA): you can’t exclude or limit liability for death or personal injury caused by negligence. Other negligence can only be limited if reasonable. UCTA also restricts excluding certain implied terms. Reasonableness looks at bargaining power, transparency, insurance, pricing and market practice
• Consumer law: if you deal with consumers, the Consumer Rights Act 2015 imposes stricter fairness and transparency tests. Most business-to-business contracts fall under UCTA, but anything involving consumers faces tighter rules
• Public policy carve-outs: you can’t exclude liability for fraud or fraudulent misrepresentation. Attempts to exclude deliberate wrongdoing, such as wilful misconduct, are usually ineffective. Sector-specific laws, such as data protection, may also set minimum obligations.

Applying liability caps and exclusions in practice

A modern liability clause usually includes:

• An overall cap (fixed or, for services, a rolling 12 months’ fees)
• Targeted super-caps for higher-risk areas, such as data protection, confidentiality or IP
• Clear excluded heads of loss
• Rules on whether the cap is per claim or aggregate, including related claims
• Fair time limits
• Alignment with insurance.

Be explicit about indemnities, which are contractual promises to compensate for specified losses or third‑party claims. State whether they sit inside the cap, under a super-cap or uncapped, and who controls defence and settlement.

Reasonableness in practice

Reasonableness is assessed when the contract is made. Key factors include bargaining power, clarity and prominence, insurance, pricing and industry norms.

If a clause removes any meaningful remedy for the core bargain – for example, excluding all loss of data in a data processing contract – you can expect challenge unless you offer a sensible carve-out or super-cap.

Common pitfalls

Over-broad exclusions that cut across the essential bargain are vulnerable. Define excluded heads of loss, use clear language, set a clean order of precedence, avoid accidentally uncapped indemnities, keep claim notice requirements proportionate and aggregate related claims so multiple small claims can’t bypass the cap.

How to refresh your contractual positions this year

Reassess your risk profile. Update fixed caps eroded by inflation and consider fee-linked caps or indexation. Re-check insurance limits and align your caps and super-caps.

Replace blanket exclusions of loss of profit or loss of data with tailored drafting that preserves core remedies while excluding remote loss. Clarify aggregation, set fair time bars (for example, prompt notice and an 18 to 24-month longstop) and standardise tiers by contract type.

Supplier and customer perspectives

Suppliers tend to prefer aggregate, fee-linked caps, exclusions of indirect loss and super-caps rather than uncapped exposure. Customers often push for higher caps, targeted carve-outs (including direct loss of profit where appropriate) and super-caps for high-impact risks.

Overall, limitation and exclusion clauses shouldn’t be applied in a blanket or boilerplate way; they should be tailored. UK law sets boundaries, but there’s wide scope for robust, fair and commercially sensible risk allocation. Use the new year to align your limits with your offerings, insurance and market practice – and present them clearly so they stand up when it matters.
