Which IR35 and rights clauses matter in UK creator contracts?

What to take away

Why IR35 status matters before a fitness creator signs

IR35 is the tax rule that decides whether a contractor working through an intermediary is taxed as employed or self-employed for that engagement. Most UK fitness creators work as sole traders, so IR35 in the strict sense does not bite.

The wider question does: HMRC can still argue that a long, controlled, exclusive brand arrangement is employment for tax purposes, and the tax bill follows.

Off-payroll working rules apply where a creator trades through a personal company and a client is a medium or large private sector business, or a public body. The client then decides status and issues a Status Determination Statement. If you are a limited company creator, that statement is the document to read first.

Employment status turns on control, substitution, mutuality of obligation and financial risk. A brand that sets your filming hours, approves every edit and pays a fixed monthly retainer looks more like an employer than a client.

The background on working hours and employment contracts is set out in the government guidance on contracts of employment and working hours.

For a creator, the practical stakes are National Insurance, income tax and penalties. A reclassification years later can wipe out a season's profit. It also affects whether you can claim expenses, run a pension or claim Universal Credit in a quiet quarter.

The clauses that shift the balance are the ones on control, exclusivity and substitution. If the brand can direct how, when and where you work, and you cannot send anyone else, the engagement reads as employment. Ask for those clauses to be narrowed before you sign.

Using the HMRC CEST tool and reading the result honestly

The HMRC CEST tool is a free online checker that asks about your working arrangements and returns an employment status indication. It is designed for off-payroll working cases, so sole traders should treat it as a guide rather than a ruling. The official checker sits at Check employment status for tax (CEST) - GOV.UK.

Answer the questions as the contract actually operates, not as you hope it will. If the brand controls your schedule, say so. If you can send a substitute, say so and make sure the contract allows it. A result built on wishful answers is worthless if HMRC later asks for the file.

Save the PDF output and the date. Keep it with the signed contract, the brief and the invoices. If HMRC opens a compliance check, a dated CEST result plus consistent paperwork is far stronger than an after-the-fact explanation.

CEST does not cover every situation. It struggles with part and parcel arrangements, where a creator is embedded in a brand team, and with multiple short engagements for one client. If your work looks like that, take paid advice from an accountant who knows the creator sector.

A CEST result is not binding on HMRC and it is not a contract term. It is evidence. The contract, the working reality and the paperwork should all point the same way.

What to put in the contract

Content rights, licensing and usage terms in creator contracts

Content rights and licensing decide what the brand can do with your footage, photographs and posts after the campaign ends. Copyright protects the original work you create, and the government explains the basics at Intellectual property: Copyright - GOV.UK.

The wider picture of what counts as intellectual property is covered in Intellectual property and your work: What intellectual property is - GOV.UK.

Read the grant of rights clause line by line. A perpetual, worldwide, irrevocable licence lets the brand use your face and voice in paid media forever, in any format, with no further fee. That is a bad deal for a fitness creator whose image is the product.

Push for a licence, not an assignment. A licence keeps ownership with you and sets limits: named channels, a set territory, a fixed term and a defined purpose. An assignment transfers ownership, and you may never get it back.

Watch for the word "all media now known or hereafter devised". It is standard in agency templates and it is unlimited. Ask for a list of channels instead: the brand's own social accounts, its website, paid social, email, in-store screens. Anything outside the list needs a new fee.

Usage fees should scale with scope. A three-month organic licence on the brand's own channels is worth far less than a twelve-month paid media licence across several markets. Price the two separately so the brand sees the difference.

Rights terms to negotiate

If the brief also covers health claims, testimonials and consumer rights, the points in claims, disclosure and rights are worth reading alongside the licensing terms.

Disclosure clauses that keep a campaign inside the CAP Code

Written by the Committee of Advertising Practice and enforced by the Advertising Standards Authority, the CAP Code is the UK's advertising rulebook. It requires marketing communications to be obviously identifiable as such. The full codes are published at Advertising codes - ASA | CAP.

Disclosure clauses should say who labels the content, when and how. The brand carries responsibility for the campaign, and the creator carries it for their own posts. A clause that pushes all liability onto the creator while the brand controls the wording is one to challenge.

A workable clause names the label, the placement and the timing. "Ad" or "advertisement" at the start of the caption, before the "more" cut, is the safest. Hashtags buried after thirty others, or a tag on a Story that vanishes in seconds, are weak.

Gifted products and free memberships count as payment in kind. If a brand sends kit, a class pass or a hotel stay with no other payment, the content still needs a clear label. A written disclosure policy for fitness creators that triggers on benefit rather than format removes the guesswork.

Affiliate links, discount codes and commission arrangements are commercial relationships too. The clause should cover them, and it should say who tracks the link and who reports the sales.

Health and fitness claims sit under the same code. Do not repeat a brand's claim that a programme treats a condition unless the evidence supports it, and keep the substantiation file. The ASA publishes rulings regularly, so check the category before you accept a brief.

Disclosure clause wording to ask for

Exclusivity, termination and payment terms to check

Exclusivity terms stop you working with competing brands for a period. A narrow exclusivity, limited to direct competitors and to the campaign window, is normal. A broad clause covering all sports nutrition, all apparel or all gyms for twelve months can cost you more than the fee.

Check the definition of competitor. "Any brand in the health and wellness sector" is too wide. Ask for a named list of no more than five brands, and a carve-out for work already booked.

Termination clauses should work both ways. Look for the notice period, what happens to fees already earned, and whether the brand can cancel after you have filmed. Kill fees of 50 per cent after shoot day and 100 per cent after delivery are reasonable starting points.

Payment terms matter more than the headline fee. Thirty days from invoice is standard; sixty days is common and painful for a sole trader. Ask for a deposit on larger campaigns and stage payments on delivery.

Late payment is a real risk for small creators. The statutory right to interest on late commercial payments applies to business-to-business debts, and a clause that tries to waive it is worth challenging. Keep invoices, delivery dates and chase emails in one folder.

If the campaign involves collecting follower data, email sign-ups or health screening answers, the contract needs a data clause. The duties around data protection from sign-up apply to the brand and to you as a controller or processor.

Common questions

Do UK fitness creators need to worry about IR35 if they are sole traders?

IR35 applies to contractors working through an intermediary, so a sole trader is outside the off-payroll rules in the strict sense. The employment status question still matters, because HMRC can argue that a controlled, exclusive arrangement is taxable employment.

Is the HMRC CEST tool result legally binding?

No. CEST gives an indication based on your answers and HMRC is not bound by it. It is still useful evidence if you answer honestly and keep the dated output with your contract and invoices.

Who owns the content a fitness creator makes for a brand?

Copyright starts with the creator who made the work. A contract can transfer it by assignment or grant a licence. Keep ownership and grant a limited licence unless the fee reflects a full buyout.

Who is responsible for labelling an ad under the CAP Code?

Both sides carry responsibility. The brand is accountable for the campaign and the creator for their own posts, so the contract should set out who supplies the label and when it appears.

Can a brand stop me working with competitors after a campaign?

Only if you agreed to an exclusivity clause. Keep it narrow: named competitors, a short period and a carve-out for work already booked.

What should I do if a brand sends a contract with a perpetual rights clause?

Ask for a fixed term and a channel list instead, and price any extension separately. If the brand will not move, decide whether the fee justifies losing control of your footage for good.
