Most freelancers who get burned by clients could have avoided the situation with a better contract. Not a solicitor-drafted 40-page document, but a clear written agreement covering the specific scenarios that actually cause disputes: scope changes, late payment, project cancellation, and intellectual property ownership.
A contract is not there for the easy projects with good clients. It is there for the situations you hope will not happen but need to be ready for. This guide covers the clauses that matter, how to read and respond to client-supplied contracts, and the behaviours that signal problems before you sign.

Why Written Contracts Matter
Verbal agreements are legally enforceable in the UK. If a client asks you to do work, you agree, and they later refuse to pay, you can pursue them in court even without a written contract. But proving what was agreed, what the price was, what the scope included, and what the payment terms were is dramatically harder without written evidence.
A written contract does not eliminate disputes. It eliminates ambiguity, which is where most disputes start. When a client says "this was not what we agreed" and you have a signed document that describes exactly what was agreed, the dispute often resolves quickly. When there is no written agreement, the dispute becomes a credibility contest.
For project-based work, a simple agreement covering scope, price, timeline, and payment terms is the minimum. For ongoing retainer relationships, you also need clarity on notice periods, intellectual property, and what happens if the relationship ends.
Essential Clause 1: Scope of Work
This is the most important clause in any freelance contract, and the one most often written too vaguely.
The scope of work clause defines exactly what you will deliver. Not in general terms ("a website" or "marketing support"), but in specific, measurable terms that make it clear what is and is not included.
A weak scope: "Design a website for the client's business."
A strong scope: "Design and build a website comprising a homepage, about page, services page, and contact form. Includes up to 5 pages. Does not include ongoing maintenance, content writing, SEO optimisation, or photography. Delivered as a staging site for client review."
The specificity of your scope clause determines how much scope creep you will experience. If the scope is vague, every additional request the client makes can be framed as "I thought this was included." If the scope is precise, additional requests are clearly out of scope and you can discuss them as paid additions without conflict.
Your scope clause should also define what you are not delivering. That negative definition is often where the most disputes arise.
Essential Clause 2: Payment Terms and Late Payment Interest
Your contract should state the total fee, the payment schedule (upfront deposit, milestone payments, payment on completion), and the payment terms (Net 7, Net 14, Net 30).
For projects of any significant size, a deposit clause is important. A deposit of 25% to 50% of the total project fee paid before work begins protects you against the project being cancelled after you have invested significant time. It also filters out clients who are not serious.
Your late payment clause should state that if payment is not received by the due date, interest will accrue at 8% above the Bank of England base rate, in line with the Late Payment of Commercial Debts (Interest) Act 1998. You are entitled to this by law, but referencing it explicitly in your contract makes clear that you know your rights and will exercise them.
Some freelancers also include a work suspension clause: if payment is not received within a specified period after the due date (for example, 14 days), you are entitled to suspend work on the project until payment is made. This gives you practical leverage beyond the legal right to charge interest.
Essential Clause 3: Revision Rounds
This clause prevents one of the most common and corrosive forms of scope creep: endless revisions.
State clearly how many rounds of revisions are included in the project price, what constitutes a revision round, and what happens if additional revisions are requested beyond the included rounds.
A reasonable clause might read: "The project fee includes two rounds of revisions. A revision round is defined as one set of consolidated feedback following delivery of a draft. Additional revision rounds beyond the two included will be charged at the day rate of £X per day."
Without this clause, a client can send feedback, then send more feedback on the updated version, then request changes to things they previously approved, and the project never ends. With this clause, you have a clear mechanism to say "this is revision round 3, which is not included in the scope, and here is the cost to proceed."
Essential Clause 4: Intellectual Property Ownership
Who owns the work you create matters. The default under UK copyright law is that copyright belongs to the creator, which in most cases means you, the freelancer. This can surprise clients who assume that paying for work means they own it.
Your contract should specify clearly when and how IP transfers to the client.
The most common arrangement for creative and design work: the client receives full ownership of the final deliverables upon receipt of payment in full. Until final payment is made, you retain ownership and grant only a limited licence to use the work.
This means that if a client does not pay, you can legally require them to stop using the work you created. This is meaningful leverage, particularly in design, copywriting, software development, and similar fields.
Specify also what happens to unused work and working files. Do source files transfer with the project? Is there a separate fee for source files? Are unused concepts or drafts your property to use elsewhere?
If your work will include licenced third-party components (stock photography, fonts, libraries), make clear that those licences are the client's responsibility to maintain after the project ends.
Essential Clause 5: Kill Fee and Cancellation Terms
Projects get cancelled. Clients change strategy, run out of budget, or simply change their minds. A kill fee clause ensures you are compensated for the work done and the opportunity cost of the time you allocated to the project.
A standard kill fee structure: the deposit is non-refundable, and if the project is cancelled after a certain point (for example, after delivery of the first draft or after 50% completion), an additional percentage of the total fee is payable.
Be clear about how project completion is defined and measured. "50% complete" is vague. "After delivery of the first draft to the client" is specific.
The kill fee should be proportional to the impact on you: a project that required significant upfront research, planning, or custom work justifies a higher kill fee than a straightforward repeatable task.
Some freelancers use a time-and-materials model rather than a fixed fee, in which case the kill fee is simply "all hours worked to date at the agreed day rate." This is often simpler to administer and avoids disputes about what percentage complete the project was.
Essential Clause 6: Confidentiality
If you will have access to commercially sensitive information (client strategy, pricing, customer data, unreleased products, financial information), a confidentiality clause is appropriate.
A basic confidentiality clause covers: the definition of confidential information, your obligation to keep it confidential, the exceptions (information already in the public domain, information you knew before the engagement), and the duration of the obligation.
For most freelance work, a simple mutual confidentiality clause that covers both parties is appropriate and uncontroversial. Clients will often ask you to sign an NDA (non-disclosure agreement) before briefing you. Review it carefully, particularly for provisions about what you can say about the work you did (some clients want to prevent you from listing them as a client or showing the work in your portfolio).
Essential Clause 7: Dispute Resolution
Including a dispute resolution clause sets expectations about how disagreements will be handled and can avoid immediate escalation to litigation.
A common structure: both parties agree to attempt to resolve disputes through good-faith negotiation first, followed by mediation if direct negotiation fails, and litigation only as a last resort.
For smaller amounts, specify that claims will be handled through the UK Small Claims Court (claims up to £10,000) rather than through a solicitor, which is faster and cheaper for both parties.
Include the governing law clause: "This agreement is governed by the laws of England and Wales." This is important if you work with international clients, as it establishes which legal system applies to any dispute.
What to Watch for in Client-Supplied Contracts
Many clients, particularly larger organisations, will send you their own standard contractor agreement rather than accepting yours. Read it carefully. Common problem clauses include:
Unlimited revisions. Language like "the contractor will make all changes requested by the client" with no defined limit or additional cost mechanism. This is scope creep written into the contract.
IP transfer before payment. Some contracts specify that IP transfers on delivery, not on receipt of payment. This removes your ability to withhold IP as leverage for non-payment. Push back on this: IP should transfer when the final payment clears.
Broad non-compete clauses. A clause preventing you from working with any other client in the same sector for a period after the engagement can significantly restrict your business. Review the scope and duration carefully, and negotiate to limit it to direct competitors or to a shorter period.
Liability caps that protect only the client. Some contracts limit the client's liability to the project fee but place no such cap on your liability to the client. In practice, this means the client can pursue you for unlimited damages but you can only recover the project fee. Push for symmetry.
Unilateral termination without notice. The ability for the client to terminate the agreement immediately and at will, with no notice period and no kill fee. You need a reasonable notice period and compensation for work completed.
Assignment clauses. Some contracts allow the client to assign the contract to another party (for example, if the client is acquired). This means you could end up contracted to a company you did not choose and know nothing about. Include the right to terminate if the contract is assigned without your consent.
Red Flags in Client Behaviour
Sometimes the warning signs appear before a contract is even discussed. Pay attention to:
Resistance to putting anything in writing. "We don't need a contract, we trust each other" means the client does not want you to have legal protection. Trustworthy clients do not object to a contract.
Unwillingness to pay a deposit. On any project of significant size, a client who refuses to pay any deposit upfront is either a cash flow risk or not sufficiently committed to the project. Both are problems.
Pushing to start before the contract is signed. "Can you just get started, we'll sort the paperwork" means the contract will be "sorted" after you have invested time and established leverage for non-payment. Never start work without a signed agreement.
Excessive urgency combined with vague scope. A client who needs things done immediately but cannot clearly articulate what they want will create problems throughout the project.
History of disputes with other freelancers. If you hear from other freelancers in your network that a particular client is difficult, has disputed invoices, or has a history of non-payment, take that seriously.
Building Your Contract Practice
You do not need a lawyer on retainer to have good contracts. You need clauses that clearly address scope, payment, IP, revisions, cancellation, and disputes, written in plain English that both parties understand.
Use the Contract Clause Generator to build out the specific clauses for your project type and review them carefully before sending. Once you have a contract template that works, it takes minutes to adapt it for each new project.
Pair your contracts with a proper Invoice Generator that references the agreed payment terms, and a Freelance Rate Calculator to ensure the rates you quote actually sustain your business. The combination of a good contract, accurate invoicing, and appropriate rates is the foundation of a financially stable freelance practice.
