Commercial contracts: What you need to know
English contract law is widely regarded as flexible and business friendly. Built on common law principles, it gives parties the freedom to agree on terms with minimal restrictions (as long as those terms are not illegal or contrary to public policy).
However, some commercial contracts must comply with specific laws and regulations, particularly in regulated sectors or public procurement. There are also stricter rules for contracts with consumers.
English law is usually chosen as the governing law in commercial contracts within the UK. While this section focuses on English law, note that contractual principles under Scots law and Northern Irish law may differ in certain areas.

Contract formation
Under English law, a contract does not need to be in any particular form (subject to certain exceptions). An agreement can even be made informally by email or orally. However, for a legally enforceable contract to be formed, these four key elements must be present:
1. Offer: The offer made by one party must be specific and complete enough for the other to accept. If the offer includes terms by reference, the other party must have a reasonable chance to read them before the contract is concluded.
2. Acceptance: The acceptance must be clear and unconditional. Typically, it needs to be communicated to be legally effective, although, in some situations, conduct may signify acceptance.
3. Consideration: As a general rule, a party to a contract can’t enforce a promise unless they have given or promised something in exchange (even if it’s just a nominal amount).
4. Intention to create legal relations: Both parties must intend to enter a legally binding agreement.

Statutory and common law controls
Implied terms: Beyond the express terms agreed between the parties, certain terms may be implied into commercial contracts. This might be due to your previous dealings, what you both intended or by statute. For example, the Sale of Goods Act 1979 and the Supply of Goods and Services Act 1982 imply some terms into business contracts – like goods matching their description, satisfactory quality and fitness for purpose. You can exclude some of these, but the Unfair Contract Terms Act 1977 (UCTA) restricts exclusions in some cases or may require them to meet a ‘reasonableness test’.
Limiting liability: Limitation and exclusion provisions are usually the most complex and heavily negotiated clauses in commercial contracts. Some of the rules are set by statute, others by the English courts. Some liabilities can’t be limited by a contract term, while others may only be limited if the terms are clear and reasonable (where UCTA applies). It's vital to draft limitation or exclusion clauses carefully to ensure compliance with the relevant rules. Similarly, you need to take care to make sure that any liquidated damages don’t fall foul of the common law requirements against penalties.
