Can a Freelancer Get a Binding Agreement From a Company?

Yes. A UK company is legally bound by an agreement with you once it accepts a clear offer to do work for payment, and both sides intend the deal to count. That acceptance can be an email, a purchase order or simply letting you start, and for most freelance work no signature is needed at all.

The harder part is proving what the company committed to. If there is a dispute later, it is likely to be about which terms were in the deal: the price, the payment date, who owns the work, and what happens if the project is cancelled.

This guide covers how to get a company's agreement in a form that holds up, what to do when it sends back its own terms or refuses to sign, and what a binding agreement gets you if things go wrong. If you already have a contract from a client and want to know whether it is valid, and which of its clauses would fail, read our guide to whether your freelance contract is legally binding instead.

Key Takeaways

A company can be bound without a signed contract. An offer, an acceptance, payment for your work and an intention to be bound are enough, and they can be written, oral or implied by conduct.

The strongest low-effort version is a complete written quote plus a written reply that accepts it without changes, from someone at the company with authority to agree.

If the company answers with its own purchase order or standard terms, it has not accepted yours. Settle which terms apply, in writing, before you start work.

Gaps have defaults. With no agreed price, a business customer must pay a reasonable charge. With no agreed payment date, payment is late 30 days after your invoice or the work, whichever is later.

A company that pays late under a binding agreement owes statutory interest at 8% plus the Bank of England base rate, unless your agreement sets its own interest rate, plus a fixed sum of £40, £70 or £100 depending on the size of the debt.

Is an agreement with a company legally binding without a signed contract?

Usually, yes. HMRC's guidance describes a contract as "an agreement between two or more parties which is intended to be legally binding", and says it "can be written, oral, implied or a combination of these" (HMRC Employment Status Manual, ESM0506). The elements it lists are an offer and its acceptance, consideration (you do the work, the company pays) and an intention to enter into legal relations. Between a freelancer and a company doing business, that intention is rarely in doubt.

A signature is not one of those elements. The Law Commission, in its report on electronic signatures, says most contracts governed by the law of England and Wales "can be made informally; they are not required even to be recorded in writing, and may be created orally or by conduct" (Law Commission, Electronic execution of documents, para 2.7). Signing, it adds, "helps prove the parties' intentions when the agreement was made, especially in the event that things go wrong."

A few kinds of contract must be in writing by law, such as a contract to sell an interest in land (Law of Property (Miscellaneous Provisions) Act 1989, s.2). A contract to provide freelance services is not one of them. One part of the deal does need writing: if copyright in your work is to pass to the company, the transfer is not effective unless it is in writing signed by you or on your behalf (Copyright, Designs and Patents Act 1988, s.90(3)).

One exception: if the company marks its emails or drafts "subject to contract", or says nothing is binding until signed, there is normally no contract until it is signed. Starting work does not reliably change that, because courts "will not lightly" find the condition was dropped (RTS Flexible Systems v Müller, Supreme Court, 2010). Get written confirmation that the deal is agreed before you start.

In short: unless it said "subject to contract", a company that accepted your quote by email has made a binding agreement with you. What a signed document adds is evidence, and evidence is what you need when the company later remembers the deal differently. For more on the four elements and how they apply to a contract a client sends you, see what makes a UK freelance contract valid.

How do you make a company's agreement legally binding?

You make it binding by getting a clear offer accepted, and you make it provable by getting both in writing. These six steps cover almost every engagement with a company, from a one-off project to a rolling retainer.

Put a complete offer in writing: Send a quote or proposal that states the scope, the price, the payment date, who owns the work and when, how changes are priced, and what happens if the company cancels. An offer that leaves the price or the deliverables open gives the company room to argue about what it accepted.
Ask for a written acceptance with no changes: HMRC's summary of contract law says acceptance "must be unqualified" (HMRC Insurance Premium Tax Manual, IPT03650). So ask for exactly that: "Please reply to confirm you accept this quote as written." A reply that says "yes, but" is a new proposal, not an acceptance.
Get it from someone who can agree: Under section 43 of the Companies Act 2006, a company makes contracts through "a person acting under its authority, express or implied". A director, a budget holder or the manager who commissioned you will usually have that authority. If your contact is junior, copy in their manager or ask who signs off spend.
Use an e-signature if they will sign: The Law Commission concluded that an electronic signature "is capable in law of being used to execute a document" where the person signing intends to authenticate it, and the Government confirmed its agreement in March 2020 (Law Commission). Electronic signatures are also admissible as evidence in court under section 7 of the Electronic Communications Act 2000.
Take a deposit before you start: The law does not require one. In practice, a paid deposit against your quote is strong evidence that a deal was done, and it caps what you lose if the company walks away.
Keep the record together: Save the quote, the acceptance, your call notes and every change request in one place. If you agree something on a call, email a short summary the same day and ask for a one-line confirmation.

Take Nadia, a UX designer who quotes £4,800 for a six-week app redesign. Her quote sets out the deliverables, two rounds of revisions, 50% upfront and 50% within 14 days of handover, and ownership of the designs passing on final payment. The company's head of product replies: "Accepted as written, PO to follow." Nobody signs anything. When the company later asks for a third round of revisions at no charge, Nadia points to the accepted quote, which allowed two, and prices the extra round at her day rate. The quote and that one-line reply are the agreement, so when the PO arrives she checks it does not try to attach different terms.

If the company sends its own contract instead of accepting your quote, have it reviewed before you reply, so you know what you would be agreeing to.

What if the company replies with its own terms or a purchase order?

Then the company has not accepted your offer as written. An acceptance has to be unqualified, so a purchase order or supplier agreement that changes your terms is the company's own proposal, and you get to decide whether to agree to it. That is why starting work before the point is settled is risky. Where each side sends its own terms, the courts usually treat the last set sent as the one accepted, and starting the work can be that acceptance (HCR Law).

This is common where a company buys through a procurement system. The system issues a purchase order, and the PO says it is subject to the company's standard terms of purchase. Those terms often differ from your quote on exactly the clauses that matter to a freelancer:

Payment: 60 or 90 days instead of 14 or 30. Gov.uk says an agreed payment date "must usually be within 30 days for public authorities or 60 days for business transactions", although a longer period can be agreed if it is "fair to both businesses" (gov.uk).
Ownership of the work: transferring the moment you create it, rather than when you are paid. Our guide to IP ownership in freelance contracts explains why the timing matters.
Liability: no cap, or indemnities you did not price for.
Cancellation: the company can cancel at any time and pay only for finished milestones.

Before you start, read the terms the PO refers to, and ask for a copy if they are only "available on request". Then reply in writing. Either accept them, or say which terms from your quote apply and ask the company to confirm. If its system cannot change the PO, ask someone with authority to confirm by email that your quote's terms on payment and ownership take priority over the standard terms.

Callum, a freelance copywriter, quotes £2,400 for a website rewrite with payment in 14 days. The client's procurement team sends a PO "subject to our standard terms of purchase", which set payment at 90 days from the end of the month and give the company ownership of every draft from the moment he writes it. Callum spots it before he starts. He replies that his quote's payment and ownership terms apply, and the marketing director confirms by email that the quote takes priority. Ten minutes of email saves him a three-month wait for his money and an argument about which document governs.

What if a company won't sign a contract?

A company that will not sign can still be bound. Some companies only sign contracts on their own paperwork, and the agreement can be made by email or by conduct instead. Your aim is to get the same commitment in a form the company will give:

Send a confirmation email after every call: "Following our call today, here is what we agreed: [scope, price, payment date, ownership]. Please reply to confirm and I will start on Monday." A one-line "confirmed" is far better evidence than no reply at all, so wait for it.
Put your terms in the quote, and refer to the accepted quote on every invoice.
Ask for a deposit against the quote.
Split long projects into stages, so each stage is agreed and paid for before the next begins.

If the company still will not put anything in writing, two default rules cover the most common gaps. Both apply whether or not anything was signed.

If no price was agreed

Where the price for a service is not set by the contract or by how the two of you have dealt in the past, section 15 of the Supply of Goods and Services Act 1982 implies a term that the customer "will pay a reasonable charge". What counts as reasonable "is a question of fact", so your usual rate, earlier invoices to the same company and market rates all become evidence. The section applies in England, Wales and Northern Ireland, and covers service contracts other than those between a trader and a consumer (section 12).

If no payment date was agreed

Gov.uk's guidance on late commercial payments says that where no date was agreed, payment is late 30 days after the customer gets the invoice, or after you deliver the service if that is later (gov.uk). An agreement with no payment terms still has a payment deadline.

What can you do if the company breaks the agreement?

You can enforce it like any other contract. A binding agreement, signed or not, gives you the right to be paid on its terms, and the law adds interest and recovery costs when a business pays another business late:

Statutory interest of "8% plus the Bank of England base rate for business to business transactions", unless your agreement sets a different rate: "You cannot claim statutory interest if there's a different rate of interest in a contract" (gov.uk).
A fixed sum for recovery costs: £40 on a debt up to £999.99, £70 from £1,000 to £9,999.99, and £100 on £10,000 or more (gov.uk).
A court claim. You can apply to a county court for money a business owes you, and claim online if you know the amount and both you and the company have an address in England or Wales. Scotland and Northern Ireland have a different process. Gov.uk also notes that mediation "could be quicker and cheaper than going to court" (gov.uk).
Time to act. In England and Wales, a claim on a contract like this must be brought within six years of the date the cause of action arose (Limitation Act 1980, s.5).

Ifeoma, a freelance illustrator, agrees £1,500 for a set of product illustrations by email with a company's marketing manager. Nothing is signed. She delivers, invoices, and hears nothing for two months, and then the company says it "never signed anything". Ifeoma replies with the email chain showing her quote and the manager's acceptance. She adds statutory interest and the £70 fixed sum to the amount due, and says she will start a court claim in 14 days if it is not paid. The invoice is paid that week. The email chain did the work a signed contract would have done.

Our guide to payment terms in freelance contracts walks through chasing a late invoice step by step.

What should a short agreement with a company cover?

A short agreement only needs the terms that cause disputes. Whether it is a one-page contract, a quote the company accepts or a confirmation email, check that it covers:

Who the parties are: the company's full legal name, not a trading name, so you know which business owes you the money.
The scope: the deliverables, the number of revisions, and what is out of scope.
The price: a fixed fee or a day rate, plus any expenses.
When you get paid: the deposit, the payment date and any milestones.
Changes: how extra work is requested and priced.
Ownership of the work: who owns it, and whether ownership passes on payment.
Cancellation: how much notice each side gives, and what you are paid for work already done.
Liability: a cap on what you could owe if something goes wrong.

Getting a legally binding agreement from a company: the short version

A company does not need to sign anything to be legally bound to you. It needs to accept a clear offer, and the best evidence of that is your written quote and its written reply. Make the offer complete, get the acceptance from someone with authority, settle any purchase order terms before you start, and keep the record together. If the company still will not sign, the defaults on price and payment dates protect you, and late payment law gives you interest and recovery costs if it does not pay.

When a company does send back its own contract or standard terms, that is the moment to check them. Ookulli reviews your freelance contract: your first contract is free, then £10 per document, with no subscription, no AI training on your documents and a 30-day money-back guarantee. It flags risky terms and missing protections in plain language and names the UK law where there is one, so you know exactly what you are agreeing to before you start work.

Frequently asked questions

Is an email agreement with a company legally binding in the UK?

Yes, if the emails show an offer, an acceptance of it without changes, payment for your work and an intention to be bound. Contracts "can be written, oral, implied or a combination of these" (ESM0506), and an email exchange is a written one. Keep the whole chain, including the quote it refers to.

Is a verbal agreement with a client legally binding?

Yes, in principle. A contract can be oral, so an agreement made on a call can bind a company just as an email can. The problem is proving its terms later. Send an email after the call setting out what was agreed, and ask the client to reply to confirm it.

Does a contract need to be signed by both parties to be legally binding?

No, not for most contracts, including freelance services. The Law Commission says most contracts under the law of England and Wales "do not require a signature at all" (Law Commission report, para 2.7). A signature is evidence of what was agreed.

Can a company back out after agreeing by email?

Only on the terms it agreed to, or with your agreement. If your quote or its terms give the company a right to cancel, it can use that right, usually paying for work already done. If it cancels without such a right, it has broken the agreement. Fees for work you have already done can be claimed as a debt. For the rest of the job you can claim damages for what you would have earned, less what you save and any replacement work you could reasonably take on.

Is a purchase order a legally binding contract?

A purchase order can become a binding contract once it is accepted, and acceptance can be by conduct, such as starting the work. A PO often says it is subject to the company's standard terms of purchase. Read those terms before you start, and settle in writing which terms apply.

Who at a company can agree a contract with a freelancer?

Anyone acting under the company's authority, express or implied (Companies Act 2006, s.43), which usually includes directors and the managers who commission and pay for work. Someone dealing with a company in good faith does not have to check for limits on the directors' powers in the company's constitution (s.40).
