AI video for small businesses: what's real, what's risky
AI is useful for editing, captions and repurposing, workable for a consented voice, and risky anywhere it invents a person, a customer or a result. Here is the line, with the rules behind it.
In short: AI is real for transcripts, captions, clip selection, audio clean-up and repurposing a recording. A consented voice clone is workable with a signed agreement. It is risky for invented customers, results that overstate a product, and anyone's face or voice without permission. A person should approve everything.
AI is useful for a small business making video in some places and a liability in others. The useful places are the dull ones: transcripts, captions, clip selection, audio clean-up and turning one recording into many posts. A consented voice clone is workable with the right paperwork. The risky places are anywhere AI invents a person, a customer or a result, and anywhere it uses someone's face or voice without permission. This page is general guidance, not legal advice.
How common it already is
Wyzowl's 2026 survey of video marketers reports that 63% have used AI video tools to create or edit marketing videos, up from 51% a year earlier. So you are not early. The question is which uses are safe and worth the effort. It is a survey of 266 respondents by a video company, so read it as a direction of travel.
What is real
These uses work now and carry little risk when a person checks the result.
- Transcripts and captions. A transcript is the base for everything else: captions, show notes, quotes, clips. Check names, product terms and numbers by eye, because transcription tools get those wrong.
- Finding the clips. AI can propose which 30 seconds of a long recording will stand alone. A producer still decides, because the tool does not know what your business should not say.
- Audio clean-up. Noise reduction and levelling save time on a recording made in a bad room. They do not fix a bad microphone position.
- Repurposing. One recorded conversation can become a post calendar, with a person approving each item. This is the pattern we run for clients: transcript check, show notes, social posts, captioned clips, branded cards and scheduling, with a producer reviewing everything before it goes out.
- Drafts. AI can produce a first-draft script or outline. It sounds like everyone else's until you put your own examples and phrasing into it.
What is real but needs paperwork
A cloned voice. With the speaker's consent, a voice model can read scripts for courses, explainers and audio replies. This is workable. It is also the place where the legal footing is weakest, because UK law has no general right over a person's voice. An analysis by Pinsent Masons says no single UK law covers voice and likeness cloning and that the main routes, passing off and copyright, fit poorly. The same firm notes that recording a person's voice and feeding it into an AI model will often count as processing personal data, so consent has to be specific and can be withdrawn.
That makes the signed agreement the protection. It should say what the voice can be used for, where, for how long, what happens at the end and who checks the deletion. Our voice and likeness checklist lists the points, and how we clone a voice with consent shows the process in practice.
A website agent. A text or voice agent that answers questions from your own material, shows its sources and passes warm enquiries to a person is a sound use. It stays honest because it only answers from what you have approved.
What is risky
Invented people
An AI avatar introducing your company is a creative choice, and some businesses will like it. An AI avatar presented as a customer is a different matter. The ASA's testimonial rules say you must hold documentary evidence that a testimonial is genuine and contact details for the person who gave it, and that marketers must not pose as consumers reviewing their own products. A synthetic customer fails both.
Results that overstate the product
CAP's guidance gives the example of an AI image that overstates what a product achieves, with an AI disclosure added as if that fixed it. It does not. Disclosing AI use rarely cures a misleading message. If the image shows a result, check it against what a normal customer gets.
Somebody's face or voice
The ASA says an AI depiction of a celebrity that looks real enough to mislead people about an endorsement is likely to breach the Code. The same logic applies to your own team and to customers. Pinsent Masons notes that the UK has no standalone personality right, so the safe course is to ask and to document the answer. Do not clone a presenter's voice because it was in the footage you bought.
Handing responsibility to the tool
In a ruling on an ad produced by Google's automated tools, the ASA held the advertiser primarily responsible for compliance. The tool will not be in the dock. You will.
A quick table
| Use | Verdict | Condition |
|---|---|---|
| Captions and transcripts | Safe | A person checks names and numbers |
| Clip selection and scheduling | Safe | A person approves each post |
| Audio clean-up | Safe | The original is kept |
| Draft scripts | Safe | Your voice and facts go in |
| Voice clone of a consenting speaker | Workable | Signed agreement, deletion date, label |
| AI-generated product visuals | Risky | Matches what the product does |
| Synthetic customer or testimonial | Do not do it | Fails the testimonial rules |
| Face or voice of someone who has not agreed | Do not do it | Misleading endorsement, passing off, data protection |
What to ask a studio or agency
If someone else is making the video, ask these before you agree a price:
- Which parts of the job will use AI, and which tools?
- Will a real person review everything before it reaches you?
- Does any real person's voice or face get copied, and where is the signed consent?
- Who owns the finished files, and what do the tool's terms allow?
- Will you tell us when AI has touched something we would assume was filmed?
A good supplier answers plainly and does not mind being asked. Put the answers in the quote or the contract, so that they are part of what you agreed and not a conversation that is forgotten by the time the edit starts. If the answer to the last one is a pause, find another supplier.
Five checks before it goes public
- Would a viewer be misled? If yes, change the content. A label will not fix it.
- Is every claim true as shown? Compare each frame with real performance.
- Does every person in it agree? Real people need written consent. Synthetic people must not be presented as real ones.
- Is the AI use labelled where it changes how people read the ad? CAP's test is whether people would be misled without it. Routine edits comparable to traditional post-production do not call for a label.
- Who approved it? Name one person and keep a record of what was generated and how it was checked.
Where to start
Most small businesses should begin with the dull end of AI: transcripts, captions and a repurposing routine around a recording you make anyway. Filming real people still wins when trust is the point. The page on when to use AI and when to shoot it for real walks through that choice, and who is responsible for an AI-made ad covers the liability.
At Granary the entry point is AI brand services, from £199 a month plus VAT, which suits a small business. The AI Studio strategy day and build are priced for larger organisations with a library of expertise to work from.

Questions we get asked
Can a small business use AI-generated video in ads?
Yes. The UK has no ban and no blanket duty to label AI use. The CAP Code applies as normal, so the ad must not mislead, and you are responsible for it even if a tool made it. Check each claim and each image against what you really deliver.
Is it legal to clone my own voice, or an employee's?
Your own voice, yes. For anyone else, UK law has no general right over a voice, so you need a signed agreement that sets out the use, the period and deletion. Recorded voices are often personal data, which brings data protection duties.
Should I tell people when a video uses AI?
CAP's test is whether people would be misled without a label. If AI changes how people read the ad, say so. Routine edits comparable to traditional post-production do not need a label. Being open also builds trust, so we label synthetic voice.
