Commercial Contracts & Terms and Conditions: A Complete Guide for UK Businesses

Reviewed by the Legal Foundations editorial team. Last updated: March 2026.

Every transaction your business makes rests on a contract. Whether you’re selling products through an online shop, providing services to clients, sharing confidential information with a prospective partner, or onboarding a new supplier — a contract governs what each party has agreed to, what happens if something goes wrong, and who bears the risk.

For many UK startups and SMEs, contracts are an afterthought. Founders focus on building the product, closing the sale, and shipping the work. Legal documentation gets drafted quickly, copied from a competitor’s website, or skipped entirely. That approach works fine — right up until the moment it doesn’t, and by then the cost of fixing a contract dispute usually dwarfs what it would have cost to get it right from the start.

This guide explains the commercial contracts every UK business needs, what they must include, and how to decide when a free template is enough and when you need a lawyer.

What Is a Commercial Contract and Why Does It Matter?

A commercial contract is a legally binding agreement between two or more parties relating to a business transaction. It doesn’t need to be a formal written document — verbal agreements can be legally binding in English law — but without something in writing, proving what was agreed is extremely difficult.

A well-drafted commercial contract does several things:

  • Sets expectations clearly. Both parties know what’s been agreed, what will be delivered, when, and at what price.
  • Allocates risk. Contracts determine who is responsible if something goes wrong — whether that’s a delay, a defect, or a third-party claim.
  • Limits liability. Properly drafted limitation of liability clauses can cap your exposure if a client suffers loss as a result of your services.
  • Protects your IP. Without clear contractual provisions, ownership of intellectual property created during a project can become genuinely ambiguous.
  • Provides a mechanism for dispute resolution. Contracts can specify whether disputes go to arbitration, mediation, or court — and which jurisdiction’s law applies.

Without a contract (or with a poorly drafted one), you’re relying on the other party’s goodwill and on the courts to fill in the gaps. That’s an expensive and unpredictable approach.

The legal basis for contracts in England and Wales

For a contract to be legally binding in England and Wales, it needs:

  • Offer — one party proposes terms
  • Acceptance — the other party agrees to those terms
  • Consideration — something of value passes between the parties (usually money for goods or services)
  • Intention to create legal relations — both parties intend the agreement to be binding
  • Certainty of terms — the agreement is clear enough to be enforceable

Most commercial contracts satisfy these requirements without difficulty. The challenge is usually not whether a contract exists but what its terms actually say — which is why getting the drafting right matters.

Types of Commercial Contracts UK Businesses Need

Website Terms and Conditions

If you have a website, you need website terms and conditions. This applies whether you’re selling products, offering services, running a SaaS platform, or just providing information.

Website T&Cs (also called terms of use or terms of service) govern the relationship between your business and everyone who visits or uses your website. They typically cover:

  • Acceptable use of your site (what visitors can and can’t do)
  • Intellectual property ownership (your content, your brand)
  • Disclaimers and limitation of liability for information on the site
  • How you handle links to third-party sites
  • Governing law and jurisdiction

Without website T&Cs, you have very limited ability to prevent misuse of your content or to limit your liability for information you publish.

Note: your website T&Cs are separate from your privacy policy. Under UK GDPR, you also need a privacy and cookie policy that explains what personal data you collect, why, and how you use it. → Generate your free privacy and cookie policy

Commercial Contracts & Terms and Conditions

Terms and Conditions for Selling Goods Online

If you sell physical goods online — whether through your own website or a marketplace — you’re subject to the Consumer Rights Act 2015 and the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. These place significant obligations on you regarding information you must provide before sale, cancellation rights (the 14-day cooling-off period), returns, refunds, and more.

Your terms and conditions for selling goods online need to reflect these legal requirements precisely. Generic T&Cs copied from another site may not do that — and if yours don’t comply, you could face complaints, chargebacks, and Trading Standards issues.

Key provisions for e-commerce T&Cs include:

  • Pre-contract information (price, delivery, product description)
  • Right to cancel and returns procedure
  • Delivery terms and timescales
  • What happens if goods are defective
  • How complaints are handled

Digital Products Terms and Conditions

Digital products — software, downloads, online courses, templates, digital art, music, ebooks — are treated differently from physical goods under consumer law. Once a customer has accessed a digital product, their right to cancel may be waived. Your T&Cs need to clearly communicate this at the point of sale and obtain the customer’s acknowledgement.

Digital product T&Cs also need to address:

  • Licence terms (what the customer can and can’t do with the product)
  • Whether the product includes updates or ongoing support
  • Restrictions on redistribution or resale
  • Compatibility and technical requirements disclaimers

Master Services Agreement (MSA)

If you provide services to clients on a recurring or ongoing basis, you need a Master Services Agreement. An MSA is a framework contract that governs the overall relationship between you and a client — it covers the commercial and legal terms that apply to all work you do for them.

Individual pieces of work are then commissioned via Statements of Work (SOWs) that sit beneath the MSA, covering the specific deliverables, timeline, and price for each project.

This structure has significant advantages:

  • You negotiate the core legal terms once, not for every project
  • New work can be commissioned quickly with a short SOW
  • Disputes about a specific project are resolved under the already-agreed legal framework

An MSA for a service business typically includes:

  • Scope of services (defined by reference to SOWs)
  • Payment terms and invoicing
  • IP ownership (who owns deliverables)
  • Confidentiality obligations
  • Limitation of liability
  • Termination provisions
  • Governing law

→ Use our free Master Services Agreement template

Non-Disclosure Agreement (NDA)

An NDA (also called a confidentiality agreement) is one of the most commonly used commercial contracts. You need one whenever you’re sharing confidential information with someone outside your business — whether that’s a potential investor, a prospective partner, a freelancer, or a supplier.

NDAs can be:

  • Unilateral — only one party is sharing confidential information (and the other party agrees not to disclose it)
  • Mutual — both parties are sharing confidential information and both agree to keep the other’s information confidential

Key provisions in an NDA include:

  • Definition of what counts as “confidential information”
  • What the receiving party can and can’t do with the information
  • Exceptions (information already in the public domain, information independently developed)
  • Duration of the confidentiality obligation
  • Remedies for breach (injunctive relief is standard)

NDAs are one area where free templates work well for straightforward situations. However, if the information you’re sharing is highly sensitive — trade secrets, detailed IP, business strategies — a bespoke NDA reviewed by a solicitor is worth the investment.

Statement of Work (SOW)

A Statement of Work documents the specific deliverables, timeline, and fees for a defined piece of work. Used alongside an MSA, it keeps individual project terms clear without requiring a full contract negotiation each time.

A good SOW includes:

  • Clear description of deliverables (be specific — vague SOWs cause disputes)
  • Milestones and delivery dates
  • Fee structure and payment schedule
  • Change control procedure (what happens if scope changes)
  • Acceptance criteria (how does the client sign off on the work?)

What Must a Commercial Contract Include? Key Clauses Explained

Whether you’re drafting an MSA, a supply agreement, or a client services contract, certain clauses appear in almost every commercial contract. Here’s what they mean in plain English.

Parties and recitals

The contract opens by identifying who the parties are (full legal names and registered addresses for companies) and briefly describing the background and purpose of the agreement. This sounds obvious but errors here — using a trading name instead of a registered company name, for example — can create problems later.

Scope of services / subject matter

This defines what is being provided, sold, or licensed. For services contracts, this is often the most important section: a vague scope is an invitation to dispute. Be precise about what’s included and — just as importantly — what’s not.

Payment terms

Specify:

  • The fee (or how it’s calculated)
  • When invoices are issued
  • Payment timescales (30 days from invoice is standard B2B; shorter is better for cash flow)
  • What happens if payment is late (interest under the Late Payment of Commercial Debts (Interest) Act 1998 applies by default in B2B contracts — currently 8% over base rate)
  • Whether VAT is included or additional

Intellectual property ownership

This clause is frequently overlooked and frequently disputed. The default position in English law is that the creator of work owns the IP — which means that if you commission a freelancer to build your website, they own the code unless your contract says otherwise.

Your contract should specify:

  • Who owns IP created during the engagement
  • Whether existing IP (your pre-existing materials, their pre-existing tools and frameworks) is licensed or assigned
  • What licences, if any, are granted

Confidentiality

Even if you have a separate NDA, your services contract should include a confidentiality clause. This ensures both parties’ obligations to protect confidential information are clear in the context of the specific engagement.

Limitation of liability

One of the most commercially important clauses in any B2B contract. This limits the amount one party can claim from the other if something goes wrong. Typical limitations include:

  • A cap on total liability (often set at the value of the fees paid under the contract in the preceding 12 months)
  • Exclusion of indirect and consequential loss (loss of profit, loss of data, damage to reputation)

Note: limitation of liability clauses cannot exclude liability for death or personal injury caused by negligence (under the Unfair Contract Terms Act 1977), and in B2C contracts consumer rights override many of these limitations.

Termination

When can either party end the contract? Typically:

  • Either party can terminate for convenience on notice (specify the notice period)
  • Either party can terminate immediately for material breach
  • Specific termination rights may apply in defined circumstances

The contract should also address what happens on termination — who owns work in progress, when outstanding invoices are due, what obligations survive termination.

Governing law and jurisdiction

For UK businesses contracting with other UK businesses, this is usually straightforward: English law and the courts of England and Wales. If you’re contracting with businesses outside the UK, governing law becomes more important and specialist advice may be needed.

Entire agreement

This clause states that the written contract represents the entire agreement between the parties, superseding any prior discussions, representations, or heads of terms. It protects against claims that pre-contractual conversations created additional obligations.

When a Free Template Isn’t Enough

Free templates are a legitimate starting point. They reflect standard practice, cover the key provisions, and are far better than no contract at all. But there are situations where you should invest in a bespoke contract reviewed or drafted by a solicitor.

Consider bespoke when:

  • The contract value is significant. If you’re entering a contract worth £50,000+, the cost of a properly drafted contract is trivial compared to the risk.
  • The risk allocation matters. If the services or goods could expose you to significant liability — software that handles financial data, advice that clients will rely on, goods used in safety-critical applications — you need carefully drafted liability clauses.
  • You’re dealing with a large counterparty. If a major client or supplier presents their own standard terms, those terms will be drafted entirely in their favour. A solicitor can review them and negotiate changes before you sign.
  • There are IP complexities. Anything involving the creation, licensing, or assignment of intellectual property benefits from specialist advice.
  • You’re entering international contracts. Cross-border contracts involve choice of law, enforcement challenges, and regulatory considerations that templates don’t address.
  • There’s anything non-standard about the deal. If the transaction structure is unusual, a template is by definition not designed for it.

Common Commercial Contract Mistakes UK Businesses Make

1. Using a US template

A surprisingly common mistake. US contract templates are drafted under US law — and US law differs from English law in important ways. Clauses that work in California won’t necessarily work in England and Wales, and some will actively undermine your position. Always use UK-specific templates.

2. Not reading what you’re signing

Founders often sign client-provided contracts without reviewing them carefully. The other party’s standard terms will favour them. Key areas to check: payment terms, IP ownership, liability caps, termination rights.

3. Relying on email chains as contracts

A series of emails can constitute a legally binding contract — but it’s almost impossible to determine precisely what was agreed, what the liability position is, or what happens in a dispute. Always confirm commercial arrangements in a formal contract document.

4. Vague scope descriptions

“Website development services” is not a scope. “Development of a five-page responsive website as specified in the attached brief, including two rounds of revisions, not including copywriting or photography” is a scope. Vagueness breeds disputes.

5. Forgetting about late payment provisions

The Late Payment of Commercial Debts (Interest) Act 1998 gives you the right to charge interest on overdue B2B invoices — but many businesses don’t know this and don’t include it in their contracts. Make it explicit.

6. Not updating contracts as the business evolves

Standard terms drafted when you were a three-person startup may be wholly inadequate once you’re a 30-person company with enterprise clients. Review your standard contracts at least annually.

7. Misunderstanding incorporation of terms

For standard terms to be incorporated into a contract, they need to be brought to the other party’s attention before the contract is formed — not after. If you send your T&Cs after the client has already committed to the work, they may not be incorporated.

8. No written contract at all

Still the most common mistake of all. Many small businesses operate entirely on trust, verbal agreements, and email exchanges. This is fine until it isn’t. A short, clear written contract takes less time to draft than a single dispute takes to resolve.

Frequently Asked Questions

Do I legally need terms and conditions for my website?

There’s no specific law requiring website terms and conditions, but they are strongly advisable. Without them, you have limited ability to protect your intellectual property, disclaim liability for your content, or prevent misuse of your site. If you’re collecting personal data (which virtually every website does), you’re legally required to have a privacy policy under UK GDPR.

Are free contract templates legally binding?

Yes — if they meet the basic requirements for a valid contract (offer, acceptance, consideration, intention to create legal relations, certainty of terms), a contract drafted from a free template is legally binding. The question is whether the template adequately covers your specific situation.

What’s the difference between terms and conditions and a contract?

Both are contracts. “Terms and conditions” typically refers to standard terms that apply to all customers or transactions (website T&Cs, sale of goods T&Cs). “Contract” often implies a bespoke document negotiated between specific parties for a specific deal. The legal principles are the same.

Can I use another company’s terms and conditions as a template?

Technically you can — but it’s risky. Their T&Cs may be poorly drafted, may not be appropriate for your business model, may contain errors, and may infringe their intellectual property. Using a professionally drafted template specific to your business type is safer.

What is a “battle of the forms” and how do I avoid it?

A “battle of the forms” occurs when both parties try to contract on their own standard terms. If party A sends a quote incorporating their T&Cs, and party B sends back a purchase order incorporating their T&Cs, which set of terms governs? English law generally says the last set of terms accepted before performance governs. You can avoid this by making sure your terms are clearly communicated and accepted before you commence work.

What governs a contract if it doesn’t specify a governing law?

English courts will determine the applicable law based on a range of factors, including where the contract was performed, where the parties are based, and the nature of the transaction. For UK-based businesses dealing with UK clients, this will typically be English law — but specifying it explicitly removes any ambiguity.

How long should I keep signed contracts?

For most commercial contracts, six years is the recommended minimum — this is the standard limitation period for contract claims in England and Wales. Some contracts (such as deeds) have a 12-year limitation period. Keep contracts and any related correspondence.

When should I use a deed rather than a contract?

A deed is used when there is no consideration — for example, a guarantee or a unilateral deed of assignment. Deeds must be in writing, signed in front of a witness, and expressed to be a deed. They have a 12-year limitation period compared to six years for ordinary contracts.
