Contract on Foot: When to Use It, Risks and Practical Tips for UK Businesses

A contract on foot usually means a contract that is already in effect and still being performed. That sounds simple, but this is exactly where businesses make expensive mistakes. Founders often assume an unsigned arrangement is not binding, rely on a verbal promise that never made it into the final document, or treat a long running supplier deal as informal just because everyone has been “getting on with it”.

The problem is that once a contract is on foot, rights and obligations may already be live. You might owe payment, be locked into notice periods, face restrictions on changing suppliers, or have less room to renegotiate than you expected. If you are taking over a business, renewing terms, or accepting a provider’s standard terms, you need to know what is already operating and what risks sit inside it.

This guide explains what a contract on foot means for UK businesses, when the term usually comes up, the legal issues to check before you sign or rely on an existing arrangement, and the common mistakes that catch SMEs out.

Overview

A contract on foot is usually an agreement that has started and is continuing, even if all of the practical work is not yet finished. For UK businesses, the key question is not the label itself, but whether legally binding obligations are already running and what terms govern the relationship.

• Check whether the agreement is already binding, even if no one signed a formal long form contract.
• Confirm the current terms, including payment, scope, notice, exclusivity, liability and termination rights.
• Look for side emails, purchase orders, proposals and verbal promises that may affect the deal.
• Review whether the arrangement can be assigned, varied or ended without triggering breach.
• Make sure the contract reflects what is actually happening in practice, not just what people remember.

What Contract on Foot Means For UK Businesses

A contract on foot generally means a contract that is presently operative. In plain English, the deal is alive, performance has started or is continuing, and the parties are expected to comply with its terms.

You will often hear this phrase in commercial discussions where a business wants to know whether an existing agreement is still running. That may come up before you sign a new supplier deal, before you buy a business, before you rely on a verbal promise, or before you assume an old arrangement can simply be replaced.

When the phrase comes up in practice

For startups and SMEs, the term commonly appears in situations such as:

• a supplier relationship that started with a quote and purchase order, then continued month after month
• a service agreement that expired on paper but carried on in practice
• a commercial arrangement being transferred during a business sale or restructure
• a contractor or consultant engagement where the scope changed over time without a formal variation
• a customer contract where the work has begun but the parties are still arguing about the final wording

In each of these examples, the business risk is the same. Someone assumes the legal position is flexible, but the arrangement may already be binding and enforceable.

Does a contract have to be signed to be on foot?

No. A signed document is helpful, but it is not always essential for a contract to exist. Under UK law, many commercial contracts can arise through offer, acceptance, consideration, intention to create legal relations and sufficiently certain terms. That can happen through emails, a purchase order accepted by conduct, or parties beginning performance.

This is where founders often get caught. A director may think, “We never signed the master agreement, so we can walk away.” But if both sides acted as though the deal existed, a court may find that contractual obligations arose anyway. The exact position depends on the facts, the wording used in negotiations, and whether the parties intended not to be bound until signature.

Why the label matters

The phrase matters because it shifts attention to what is already live. If a contract is on foot, you need to ask:

• what obligations are currently running
• whether the pricing and scope still reflect the actual arrangement
• what notice or exit rights apply
• whether either party has already breached the terms
• what liabilities have built up so far

That is especially important where a business has grown quickly and paperwork has not kept pace. Many SMEs operate on a mixture of framework agreements, email approvals, statements of work and invoices. If you are not clear which terms govern the deal, disputes about payment, delay, quality, intellectual property or termination become much harder to resolve.

Examples for SMEs

A software agency agrees by email to build a platform for a retail client. The parties plan to sign a longer contract later, but development starts immediately and deposits are paid. That arrangement may already be on foot, even if the final document was never signed.

A café orders packaging from a supplier every month under terms first issued two years ago. Nobody reviews the small print. The supplier later raises prices and points to an automatic renewal clause and minimum volume commitment. The contract may still be on foot, even though the customer treated it like an informal repeat order arrangement.

A growing company wants to switch logistics providers before peak season. It discovers the current provider’s terms require 90 days’ notice and charge an early termination fee. The commercial relationship was “just rolling along”, but legally the contract remained on foot.

Legal Issues To Check Before You Sign

Before you sign a new document or rely on an existing arrangement, confirm what contract is actually in place and whether it is already binding. The main legal risk is not knowing which terms control the relationship.

1. Has a binding contract already been formed?

Start with the formation question. Look at the full document trail, not just the latest draft. This may include:

• quotes and proposals
• emails confirming price, scope or timing
• purchase orders and order acknowledgements
• statements of work
• invoices and payments
• messages showing work has begun

If the parties agreed the essential terms and started performing, a contract may exist already. If correspondence says “subject to contract”, that may help show the parties did not intend to be bound until formal signature, but those words are not a magic shield in every situation. The factual context still matters.

2. What are the operative terms?

Once you know a contract is on foot, identify the terms that apply now. Do not assume the latest draft governs. It may be the supplier’s standard terms, the customer’s purchase terms, a signed framework, or a patchwork of documents read together.

Focus on the terms that cause the biggest commercial pain if missed:

• payment timing, late payment interest and deposit rules
• scope of work and change control
• service levels, delivery dates and acceptance criteria
• automatic renewal and minimum term clauses
• notice requirements and termination rights
• exclusivity, non-compete or volume commitments
• liability caps, indemnities and exclusions
• intellectual property ownership and licence rights
• confidentiality, privacy notice and data protection obligations
• governing law and dispute resolution clauses

3. Can the contract be varied?

Many businesses think a friendly email or phone call is enough to change a deal. Sometimes it is, but not always. Some contracts say variations must be in writing and signed. Others can be varied by conduct if both sides clearly act on the change.

Before you spend money on setup or commit to a new timetable, check whether a proposed change is legally effective. If the parties have been working outside the written scope for months, tidy that up with a proper variation or replacement agreement.

4. Can the contract be assigned or transferred?

This is a major issue in acquisitions, restructures and group reorganisations. A contract on foot may not be freely transferable. The agreement might prohibit assignment without consent, or only allow it in limited circumstances.

If you are buying a business, do not assume valuable customer or supplier contracts automatically move across. You may need a formal assignment, novation, or counterparty consent. If this is missed, the buyer may not get the legal benefit of a key contract at all.

5. Are there any compliance obligations wrapped into the deal?

Some contracts contain obligations that go beyond price and delivery. For example, a service provider handling personal data may impose data processing terms. A distributor agreement might contain brand usage rules. A commercial lease side agreement could require landlord consent before works are carried out.

For UK businesses, common compliance areas include:

• UK GDPR related data processing and security commitments
• consumer law obligations where goods or services reach end customers
• industry specific standards or certifications
• insurance obligations
• anti bribery, sanctions or ethical sourcing clauses

If the contract is already on foot, those obligations may already apply, even if your team has never read the schedule where they appear.

6. What remedies are available if something has gone wrong?

If the relationship is already in trouble, do not assume you can simply rescind or terminate immediately. Remedies depend on the contract wording, the seriousness of the breach, whether notice and cure periods apply, and whether the innocent party has affirmed the contract by continuing to perform.

In practice, the sensible first step is usually to map out the breach, the evidence, the contractual notice mechanics, and the commercial outcome you actually want. That may be payment, renegotiation, a managed exit, or a clean termination. The legal route should support the business goal.

Common Mistakes With Contract on Foot

The most common mistake is treating an active contract like a loose working arrangement. Once performance has started, assumptions become expensive.

Relying on a verbal promise

A founder is told, “Don’t worry, we will not enforce the minimum term,” or “You can own the IP when the final invoice is paid.” If that promise is not reflected in the operative contract, the written terms may still control.

Before you rely on a verbal promise, confirm it in writing and make sure it is properly incorporated into the agreement. This matters most where pricing, exclusivity, renewal, IP and termination are concerned.

Ignoring standard terms hidden in the paperwork

Businesses often negotiate the headline commercial points and forget the boilerplate. Then a dispute arises and one side points to liability caps, exclusion clauses, auto renewal wording, or jurisdiction clauses buried in standard terms.

This happens a lot in procurement chains. A quote may look simple, but the reverse side, portal terms or linked order terms may contain the clauses that decide the dispute.

Letting the scope drift

Service businesses are especially vulnerable here. Work expands, deadlines move, extra deliverables are requested, and everyone carries on because the relationship feels positive. When payment is disputed, the supplier struggles to prove which work was included and which work was extra.

Use clear statements of work, approval processes and written variations. If the contract is on foot and the project has changed, update the paperwork before the next milestone is missed.

Assuming expiry means the contract is over

A document reaches its end date, but the parties continue to order, supply and pay. The legal effect can be messy. The old contract may continue on the same terms, continue only in part, or be replaced by a new contract arising through conduct.

Do not leave this to guesswork. If a contract is about to expire and the relationship is continuing, sign a renewal or extension, or at least confirm in writing what written terms apply from the next period.

Missing notice and termination mechanics

This is a classic SME problem. A business emails “we are ending the agreement” without checking the clause that requires notice to be sent to a specific address, by a specific method, within a specific timeframe.

If the notice is invalid, the contract may continue and further fees may accrue. Before you sign with a replacement provider, check the exit mechanics carefully.

Forgetting about data, IP and confidentiality

When commercial relationships move fast, businesses focus on price and timing. But contracts on foot often determine who owns work product, who can use branding, how confidential information must be handled, and what happens to customer data at the end.

If a developer built custom software, a designer created packaging, or a marketing agency had access to customer lists, these clauses can be just as important as the payment terms.

Not checking assignment during a sale or investment transaction

Founders preparing for a sale often highlight big customer contracts as valuable assets. Buyers then review the documents and discover the contracts cannot be transferred without consent, or can be terminated on change of control.

That issue can affect valuation, timing and deal structure. If your business relies on a handful of major contracts, review transfer and consent provisions well before a transaction starts.

Using inconsistent documents

One team works from a proposal, another team follows the customer purchase order, and accounts invoices under a different rate card. That inconsistency creates uncertainty about the terms on foot and weakens your position if a dispute arises.

Keep one clear contract set for each commercial relationship. If there are supporting documents, make sure they are expressly incorporated and aligned.

FAQs

Is a contract on foot the same as an unsigned contract?

No. A contract on foot means the agreement is currently operative. It may be signed or unsigned. The real issue is whether the parties are already legally bound and performing under it.

Can a contract be binding if we only agreed by email?

Yes, in many cases it can. If the essential terms are sufficiently clear and both sides intended to make a deal, emails and conduct may create a binding contract. The wording used in negotiations and the surrounding facts will matter.

What happens if the written contract expired but we kept working together?

The relationship may still be governed by the old terms, or a new contract may have arisen through conduct. The answer depends on the wording of the original agreement and what happened after expiry. It is best to document the position rather than rely on assumptions.

Can we transfer a contract on foot to a buyer or another group company?

Not always. Many contracts restrict assignment or require consent. Before a business sale, restructure or internal transfer, check whether you need an assignment, novation or approval from the other party.

What should we do before accepting the provider's standard terms?

Read the clauses that affect real commercial risk: term, renewal, exit rights, liability, IP, data protection, payment and notice. If the relationship is already underway, make sure the terms match what is happening in practice and any side promises are documented properly.
