The five things most contractor agreements get wrong
No termination provisions
Many agreements simply don’t address how the relationship ends. No notice period, no termination rights, no process for ending the contract if performance falls short or the business need changes. This leaves both parties in ambiguous territory when something goes wrong.
Nothing on tax and employment status
From April 2026, significant changes to IR35 thresholds mean more businesses are being reclassified as small companies, which affects who is responsible for determining employment status. Your contract should include a clause that sets out the contractor’s responsibility for their own tax and National Insurance, and confirms that the arrangement is outside IR35 where that is genuinely the case. This needs to reflect the actual working practice, not just the paperwork.
Inadequate data protection clauses
If a contractor accesses client data, personal information, or any data covered by GDPR, your agreement needs to address this directly. What data can they access? What security standards apply? Who is liable in the event of a breach? A vague or absent GDPR clause creates real exposure.
Unclear financial liability
A clause that loosely refers to responsibility for ‘financial mistakes’ without defining what constitutes an error, what the recovery process looks like, or what the liability cap is, is not a clause. It’s a disagreement waiting to happen.
Vague payment terms
How is the contractor paid? What is the invoicing process? What are the payment terms? What happens if an invoice is disputed? Ambiguity around money is the most common source of contractor disputes.
A real example: Barnt Green Travel Lounge
Barnt Green Travel Lounge is an independent travel agent based in Worcestershire that works with a small team of self-employed travel consultants. When they came to us, their contractor agreement had been in place for some time and needed a review.
We identified several improvements for the contract they were using for self employed workers. We reviewed termination provisions, tax liability, IR35, GDPR clauses, financial liability clauses, and information around membership fees.
We redrafted the agreement from scratch, adding clarity and updating all relevant areas. We also created a nine-page visual contractor guide, written in the agency’s own tone of voice, that explains the key elements of the agreement in plain English and helps new contractors settle into working with the business.
“From the initial conversation with Lisa, it was clear we needed to improve our contract and guide. The whole process has been seamless. If I had not spoken to Lisa initially we would have been using an outdated contract with lots of loopholes.”
How to know if your contractor agreement needs a review
If your agreement is more than two years old, it almost certainly needs a review. If it doesn’t address IR35, GDPR, or termination explicitly, it definitely does. And if you’re not entirely sure what it says on any of those points, that’s a strong signal in itself.
What a well-drafted contractor agreement should include
At a minimum, your contractor agreement needs to cover the scope of the work (what the contractor is being engaged to do and what falls outside that scope), payment terms (rate, invoicing process, payment timeframe and dispute resolution), intellectual property (who owns the work produced), confidentiality and data protection, IR35 status and tax responsibility, and termination provisions (notice periods, grounds for termination and any exit obligations).
Where a contractor accesses client data or personal information, a data processing agreement may also be required under UK GDPR. This sits separately from the contractor agreement itself but both should be in place before work begins.
For guidance on employment status and whether your contractor arrangement is genuinely outside IR35, HMRC’s Check Employment Status for Tax (CEST) tool is the starting point, though professional advice is advisable where the status is genuinely unclear.
What you should do now
- Find your current contractor agreement and read it. Is IR35, GDPR and termination addressed clearly?
- If it’s more than two years old, or was downloaded from a generic template site, it almost certainly needs updating.
- If you’re taking on a new contractor, don’t use the same agreement you’ve always used without checking it first.
- If you’re not sure what your agreement says on the key points, that’s a strong signal it needs a review.
