Rules and ethics
What the ASA CAP Code means for UK ecommerce product images?
Ecommerce photography must follow the ASA CAP Code and CMA online sales guidance, or UK retailers risk misleading claims, complaints and sanctions.
What to take away
- Ecommerce photography must not mislead under the CAP Code, and the ASA enforces this across UK retailer websites.
- Misleading enhancements, such as unrealistic retouching or implied performance, breach the Code even if the product is shown.
- Comparative claims in images need substantiation before you publish them.
- The CMA online sales guidance and the Consumer Protection from Unfair Trading Regulations 2008 add legal weight to image accuracy.
- Worked examples show how a compliant listing image differs from a non-compliant one.
- Use the ASA Copy Advice service and build an approval checklist to catch problems early.
What the ASA and CAP Code cover in ecommerce product imagery
The Advertising Standards Authority (ASA) is the UK's independent advertising regulator. It applies the CAP Code, the UK Code of Non-broadcast Advertising and Direct & Promotional Marketing, to ads in non-broadcast media. That includes retailer websites, social media posts and email marketing where they count as ads.
If your ecommerce product image appears in a paid social post, an email campaign or a website banner, the CAP Code likely applies. The Code requires that ads are legal, decent, honest and truthful. It also says ads must not mislead, and that claims must be substantiated.
For ecommerce photography, the Code's core rules mean an image must give a fair impression of the product. That covers what the product looks like, what it does and what a buyer gets. The ASA does not pre-approve images, but it acts on complaints.
The CAP Code sits alongside the UK Advertising Codes, which set rules on misleading imagery and social responsibility. The ASA publishes these codes, and they apply across the UK, from Greater London to Scotland and Wales.
If you sell through a marketplace, your listing images may still be treated as ads under the CAP Code. The same rules apply to a small seller in West Yorkshire and a large retailer in the South East.
The ASA's remit covers ads that originate in the UK, even if the website is hosted elsewhere. That means a British retailer's product images can be reviewed by the ASA regardless of where the server sits.
Before you publish product images, check the product photography advertising rules to see how the CAP Code applies to your listings.
Misleading enhancements: retouching, mockups and implied performance
Misleading enhancements are changes to a product image that give a false impression of what the buyer will receive. Not every edit is a problem. Adjusting brightness or cropping a background is usually fine. The issue is when the edit changes the meaning of the image.
Retouching is the most common area. If you remove a scratch from a refurbished laptop, the image may mislead about condition. If you slim a model's waist to sell clothing, the image may mislead about fit. The CAP Code does not ban retouching, but it bans ads that mislead.
Mockups are another risk. A mockup shows a product in a setting, such as a sofa in a living room. If the mockup makes the sofa look bigger or a different colour, it can mislead. The ASA has upheld complaints about images that exaggerated size or finish.
Implied performance is subtler. An image of a waterproof jacket worn in heavy rain may imply it keeps you dry in a storm. If the jacket is only shower resistant, the image could mislead. The claim is visual, but the CAP Code treats visual claims like written ones.
Digital enhancements that add features not present in the product are almost always misleading. Adding a logo to a plain t-shirt, or showing a phone with a case that is not included, changes what the buyer expects. That breaches the Code.
For a full picture of the UK rules that apply, read our guide to product photography compliance.
The test is whether the overall impression is accurate. Ask: would a reasonable buyer feel misled if they saw the actual product? If yes, the image likely breaches the CAP Code.
Comparative claims and substantiation in product visuals
Comparative claims in product visuals compare your product with a competitor's. That could be a side-by-side image, a before-and-after shot, or a visual that implies your product is better. The CAP Code requires that comparative claims are substantiated and fair.
Substantiation means you hold evidence before you publish. If your image suggests your battery lasts longer than a rival's, you need test data to back it up. The ASA can ask for that evidence if a complaint is made.
Comparisons must also be like-for-like. Showing your premium model against a competitor's budget model may mislead if the price difference is not clear. The visual must not create a false impression of equivalence or superiority.
Comparative advertising is allowed in the UK, but it must not discredit a competitor unfairly. The CAP Code and the Business Protection from Misleading Marketing Regulations 2008 set the boundaries. Visual comparisons that mock or misrepresent a rival can breach both.
If you use a competitor's product in your image, you may need permission. Copyright and design rights can apply. The Intellectual Property Office (IPO) provides guidance on using others' images and designs.
Before publishing a comparative visual, check that you can prove every claim it makes. If you cannot, change the image or drop the comparison. The ASA publishes its rulings, so precedents are public and easy to find.
CMA online sales guidance and the Consumer Protection from Unfair Trading Regulations 2008
The Competition and Markets Authority (CMA) enforces consumer protection law in the UK. Its online sales guidance explains how the Consumer Protection from Unfair Trading Regulations 2008 apply to ecommerce. The Regulations prohibit misleading actions and omissions.
A misleading action includes giving false information or deceiving the average consumer. A product image that hides a defect or exaggerates a benefit can be a misleading action. The CMA can take enforcement action against traders who breach the Regulations.
The CMA's guidance covers online reviews, pricing and product descriptions. It also covers images, because images are part of how a product is presented. If an image creates a false impression, it can breach the Regulations even if the text is accurate.
Unlike the CAP Code, the Regulations are law. The CMA has the option to request commitments or to initiate legal proceedings. Local authority trading standards services also enforce the Regulations across the UK, from the West Midlands to the North West.
The CMA has published guidance for businesses on consumer protection, including how to avoid misleading claims. You can find the Consumer protection guidance for businesses - GOV.UK collection on GOV.UK.
For ecommerce photography, the key point is that images must not mislead. That aligns with the CAP Code, but the legal consequences can be more severe. A breach can lead to fines, refunds or reputational damage.
If you sell to consumers in the UK, you must comply with both the CAP Code and the Regulations. The CAP Code is enforced by the ASA, while the CMA and trading standards enforce the law. They can act together on the same image.
Worked example: a compliant versus non-compliant listing image
Here is a worked example for a fictional British retailer, Fern & Flint, which sells outdoor clothing from a warehouse in Greater Manchester. The product is a waterproof jacket. The retailer has two versions of the main listing image.
The non-compliant image shows the jacket being worn in a heavy storm, with water beading off the fabric. The model is standing under a waterfall. The jacket is described as shower resistant in the text, but the image implies it is fully waterproof.
The image has also been retouched to make the jacket look thicker and warmer than it is.
This image is likely to breach the CAP Code because it misleads about performance and material. It could also breach the Consumer Protection from Unfair Trading Regulations 2008 as a misleading action. The ASA could uphold a complaint, and the CMA could require the retailer to change the image.
The compliant image shows the jacket worn in light rain, with a caption that says shower resistant. The fabric is shown as it is, without retouching that changes its thickness. The model is in a neutral pose, and the background is a plain outdoor scene. The image gives a fair impression of what the buyer will receive.
To move from non-compliant to compliant, Fern & Flint followed these steps:
- Reviewed the product's actual performance claims and matched the image to them.
- Removed retouching that changed the jacket's apparent thickness or warmth.
- Replaced the storm scene with light rain to reflect shower resistance.
- Added a clear caption stating the jacket is shower resistant, not waterproof.
- Checked the final image against the CAP Code and the CMA guidance before publishing.
This example shows that compliance is about accuracy, not about avoiding all editing. The compliant image still looks professional, but it does not overpromise.
Copy Advice, rulings and sanctions as due diligence tools
The ASA offers a Copy Advice service that gives pre-publication guidance on ad content, including imagery. It is free for ASA members and available to others for a fee. Using it before you publish can catch problems early.
The service is confidential and non-binding, but it reflects the ASA's likely view. If you are unsure whether an image is misleading, Copy Advice can help. It is particularly useful for comparative claims and implied performance.
The ASA also publishes its rulings on past cases. These are a free resource for understanding how the Code is applied. You can search the Rulings - ASA | CAP database for cases involving product photography and misleading imagery.
Rulings show what the ASA considers a breach. For example, a ruling might involve a retailer that used a mockup to make a product look larger. Reading these cases helps you avoid similar mistakes.
Sanctions for breaching the CAP Code include requiring the ad to be withdrawn or amended. The ASA can also publish the ruling, which names the advertiser. That can damage trust and lead to further scrutiny.
For serious or repeated breaches, the ASA can refer the advertiser to trading standards or the CMA. The ASA's sanctions are not fines, but the reputational and legal consequences can be significant.
Using Copy Advice and studying rulings are due diligence steps. They show that you took reasonable care to comply with the CAP Code. That can help if a complaint is made.

Building an image approval checklist against the CAP Code
An image approval checklist helps you apply the CAP Code consistently. It should be used before any product image is published on your website, social media or email. The checklist should cover accuracy, substantiation and legal compliance.
Here is a checklist you can adapt for your team:
- Does the image give a fair impression of the product's appearance and performance?
- Have all misleading enhancements been removed or justified?
- Are comparative claims supported by evidence held on file?
- Does the image comply with the Consumer Protection from Unfair Trading Regulations 2008?
- Have you checked the ASA rulings for similar products or claims?
- Has the image been reviewed by someone with compliance knowledge?
- Is there a record of the approval decision and any changes made?
The checklist should be part of your workflow, not an afterthought. For larger retailers, a compliance lead should sign off images that make performance or comparative claims. For smaller sellers, a simple review by the owner may be enough.
You should also consider whether your images need a disclosure. For example, if you use a mockup or a model, a disclosure may be needed. Our article on product photography UK regulations covers the legal side.
The CAP Code and the CMA guidance are not static. The ASA updates its advice, and the CMA publishes new guidance. Review your checklist at least annually, and after any ASA ruling that affects your sector.
Training is also important. Staff who edit or approve images should understand the rules. A short session on misleading enhancements and comparative claims can prevent problems.
Finally, keep records. If the ASA or CMA asks about an image, you will need to show how you ensured compliance. Records of approvals, evidence for claims and training logs are all useful.
Common questions
Does the CAP Code apply to my ecommerce product images? Yes, if the images appear in ads, such as on your website, social media or email marketing. The CAP Code covers non-broadcast ads, and product images are part of the ad.
What counts as a misleading enhancement? Any edit that gives a false impression of the product's appearance, performance or what is included. Retouching that changes size, colour or condition can mislead.
Can I use comparative images with a competitor's product? Yes, but you must substantiate the comparison and ensure it is fair. You may also need permission to use the competitor's product in your image.
What are the penalties for breaching the CAP Code? The ASA can require you to withdraw or amend the ad, and it can publish the ruling. Serious cases can be referred to trading standards or the CMA.
Is Copy Advice free? It is free for ASA members, but non-members may pay a fee. It provides confidential, non-binding guidance on ad content, including imagery.
How often should I review my image approval checklist? At least annually, and whenever the ASA or CMA publishes new guidance or rulings that affect your sector.
