If you run a business selling products in the UK-whether online, on the high street, or B2B-chances are you've heard about the Sale of Goods Act 1979. But what does it actually mean for your business? And are you across the legal “implied terms” that apply to every deal, whether you spell them out in your contracts or not?

This guide cuts through the legal jargon and clearly explains the essentials of the Sale of Goods Act 1979, including its key sections, how it protects buyers, and what you as a business need to do to stay compliant (and avoid disputes down the track). Let’s break down everything you need to know-so you can keep your company’s reputation, customer trust, and legal standing strong.

Keep reading to get a clear, actionable breakdown of the Sale of Goods Act and how it applies to your business.

What Is the Sale of Goods Act 1979?

The Sale of Goods Act 1979 (often shortened to “the Sale of Goods Act”) is a cornerstone piece of UK business law. For decades, it has provided a core framework for sales of goods-covering contracts between businesses and between businesses and consumers.

Essentially, the Sale of Goods Act sets out your basic legal duties when you sell physical goods. It spells out rules on what the contract must include, how risk is transferred, what happens if goods aren’t delivered as agreed, and-crucially-builds in certain “implied terms” into every sale, even if you don’t mention them in your contract.

If you’re wondering what is the Sale of Goods Act 1979 and why it’s still important, here are the headline points:

• It governs contracts for the sale and purchase of goods across the UK (except for Scotland, which has some variations)
• Applies to both business-to-business (B2B) and business-to-consumer (B2C) sales, although some rules have been updated for consumer sales (see below)
• Lays down rules on delivery, payment, risk, and what happens if something goes wrong
• Critically, it inserts key promises (“implied terms”) into every contract-protecting buyers and setting minimum standards

Today, parts of the Act (especially the consumer-facing ones) have been overtaken by newer laws like the Consumer Rights Act 2015. But the Sale of Goods Act remains absolutely crucial for all business sales, B2B contracts, and many non-consumer transactions.

Who Does the Sale of Goods Act Apply To?

The Sale of Goods Act covers a broad range of transactions-including:

• Any contract to buy or sell physical goods, including raw materials, manufactured products, equipment, vehicles, and more
• Sales of goods between businesses (B2B deals)-such as wholesaling, supply chain agreements, or trade sales
• Sales where the buyer is a “non-consumer” (i.e., making purchases for business use rather than personal/family consumption)
• Some sales to individual consumers, but note: these are now mostly governed by the Consumer Rights Act 2015 (for most retail sales, e-commerce, and direct-to-public transactions)

Critically: the Act applies whether the contract is written, verbal, or “implied” by conduct (like clicking ‘buy’ on a website). If you’re selling second-hand goods, it generally still applies-though some implied terms can be limited if the buyer agrees in full knowledge (more on this below).

What Are Implied Terms in the Sale of Goods Act?

One of the most important features of the Sale of Goods Act 1979 is its implied terms. These are legal guarantees automatically inserted into your contracts-even if you don’t mention them (or even if you try to exclude them, in some cases!).

Why does this matter? It means you can’t just write a contract saying “goods are sold as seen, with no guarantees” and walk away scot-free. The law still requires you to meet certain basic standards.

The main kinds of implied terms under the Act include:

• Right to sell the goods (good title) - Section 12
• Description of the goods - Section 13
• Quality and fitness for purpose - Section 14
• Goods correspond with sample - Section 15

Let’s break down each of these and what they mean for your business.

Section 12: Right to Sell the Goods (Good Title)

Section 12 of the Sale of Goods Act 1979 is a fundamental safeguard. It means:

• You must have the legal right to sell the goods-you’re not allowed to sell stolen or encumbered (i.e. subject to someone else’s rights, such as a finance company) items
• The buyer should get “quiet possession” of the goods (no one turns up to repossess them or claims they’re not legally the seller’s to sell)
• If you breach this, the buyer could reject the goods and claim damages-potentially placing your business at serious risk

This is particularly important for sales of cars, electronics, machinery, and other big-ticket items-for both new and second-hand sales.

Section 13: Goods Must Match Their Description

If you sell goods by reference to description (whether in-store, online, on a phone order, or via a catalogue), those goods must correspond exactly to the description provided. This is often called “sale by description.”

• If you advertise a product as “brand new, sealed box” but supply a refurbished or opened item, that’s a clear breach
• Even “trade terms” and standard product codes/descriptions form part of the legal description

Clear, accurate, and honest product descriptions are essential to avoid disputes (and potential liability) under section 13.

Section 14: Satisfactory Quality and Fitness for Purpose

This is one of the most significant obligations for UK businesses. Under Section 14 Sale of Goods Act, goods must:

• Be of “satisfactory quality” (not defective, broken, or unusable on basic inspection)
• Meet the standards that a “reasonable person” would regard as satisfactory (factoring in description, price, appearance, safety, durability, and more)
• Be fit for their usual purpose-but also for any specific purpose the buyer makes known to the seller

If you’re asked to recommend materials for a customer’s project, and your recommendation is defective for that purpose, you could be liable even if the material is otherwise fine for general use.

B2B buyers cannot always rely on the same level of protection as consumers, but the “satisfactory quality” and “fit for purpose” obligations are default law unless the contract explicitly and lawfully excludes them-which is complicated, and in many cases, not possible.

Section 15: Sale by Sample

If you make a deal based on a physical sample (for example, a fabric swatch or prototype), all goods supplied must correspond with that sample in quality. This applies to B2B deals especially (for example, bulk wholesale agreements or manufacturers’ contracts).

• All the delivered goods should match the sample-no sneaky substitutions, downgrades, or mixing in inferior items
• If the bulk goods aren’t the same quality as the sample, the buyer can usually reject them or claim damages

How Can Businesses Limit or Exclude These Implied Terms?

Some business owners wonder if they can sidestep these rules-for example, by adding “goods are sold as seen” or “no warranties are given” to their contracts.

The short answer? It’s complicated, and there are strict limits-especially when the buyer is a consumer. For B2B sales, you can sometimes exclude or limit certain implied terms, but only if the exclusion is “reasonable” under the Unfair Contract Terms Act 1977 (UCTA). For example:

• Exclusions of title (section 12) are nearly always ineffective
• Exclusions for description, quality, and fitness must be reasonable and clearly brought to the buyer’s attention
• Consumer buyers are almost always protected-most consumer transactions today fall under the Consumer Rights Act 2015, which makes it illegal to exclude most implied terms

This means you need professionally drafted contracts and terms and conditions, tailored for your business, to ensure you’re complying with the law and not risking an unenforceable term.

What Happens If You Breach the Sale of Goods Act?

If your company breaches one of the Sale of Goods Act’s implied terms, you could face a number of legal headaches, including:

• The buyer rejecting the goods and cancelling the contract
• Being legally required to offer a refund or replacement
• Claims for damages-the buyer could demand compensation for any losses suffered as a result
• Reputational damage: unhappy customers or partners are likely to leave negative reviews or warn others

In extreme cases, ongoing breaches or failure to address faults could also see you hauled before trading standards regulators or sued in civil court.

It’s essential to have strong compliance processes-like complaints handling systems and clear contracts-in place from day one.

Does the Sale of Goods Act Apply to Online Sales?

Yes-the Sale of Goods Act applies to online and e-commerce transactions, just as it does to bricks-and-mortar sales. That means your web shop, online marketplace business, or even social media sales must comply with these core rules.

B2C online sales are mainly covered by the Consumer Rights Act 2015 and other consumer protection laws, but the Sale of Goods Act still provides the key foundation for business-to-business and “goods not for personal use” sales made online.

Setting up legally compliant e-commerce terms and conditions is a must for all digital retailers and suppliers.

Is the Sale of Goods Act Still Relevant After the Consumer Rights Act 2015?

For most B2C (business-to-consumer) transactions, the Consumer Rights Act 2015 has updated and replaced many parts of the Sale of Goods Act-especially around returns, refunds, and digital content.

But the Sale of Goods Act 1979 remains absolutely vital for:

• Business-to-business (B2B) sales of goods
• Sales involving second-hand or refurbished goods (with exceptions)
• Any contract falling outside strict “consumer” definitions

Understanding your legal duties under the Sale of Goods Act is still key to risk management and compliance in these areas.

How Do You Stay Compliant With the Sale of Goods Act?

Making sure your business fully complies with the Sale of Goods Act doesn’t have to be overwhelming. Here are some smart steps you can take:

• Clearly describe your products-both online and in contracts, use accurate and honest descriptions, photos, and specifications
• Check your supply chain-work with trusted suppliers and check that any goods you’re reselling aren’t encumbered or defective
• Monitor quality-regularly check goods before delivery to ensure they meet satisfactory quality and fitness for purpose standards
• Use clear, up-to-date contracts and T&Cs-these should be properly drafted for your business, referencing the correct legal framework and protecting you if disputes arise
• Have a customer complaints system-be ready to deal with issues proactively (for tips, check our guide on writing a complaints policy)
• Train your team-make sure sales and aftercare staff understand the basics of your legal obligations under the Act

If you’re not confident your current contracts or procedures are up to scratch, it’s wise to have a legal expert review them for potential gaps.

What Legal Documents Do I Need For Selling Goods?

No matter the size or type of your business, a few core legal documents are essential if you’re selling goods in the UK:

• Terms and conditions of sale-spell out the rights, responsibilities, return/refund policies, delivery terms, and limitations of liability (see our guide)
• Goods and services agreements-these lock in deals with suppliers or commercial buyers, setting out quality requirements and compliance with the Sale of Goods Act
• Privacy Policy-if you handle customer data online, you’re also required to comply with UK privacy laws (cookie policy essentials)

Professional contracts are your best defence against disputes, non-payment, or regulatory headaches-don’t rely on DIY templates for such an important area.
