A marketing agency agreement (also called a marketing agency contract) is a formal contract between a business and a marketing agency that sets out the basis on which the agency will provide its services. Marketing agencies may provide services such as advertising, social media management, content creation, branding, search engine optimisation (SEO) or marketing strategy. A written agreement helps both parties understand what they have agreed to, manage expectations and reduce the risk of disputes over services, fees, responsibilities or expected outcomes.

Although a marketing agency agreement is a type of service contract, it is tailored to the specific relationship between a business and its marketing agency. This distinguishes it from a commercial agency agreement, under which an agent may act on a business’s behalf to negotiate or conclude the sale or purchase of goods. Businesses should ensure their agreement accurately reflects the nature of the relationship and the services provided.

This guide explains what marketing agency agreements typically cover, key legal considerations in the UK, common risks and the legal obligations of both parties. It also considers the advantages and disadvantages of fixed-term and ongoing contracts and sets out best practices for putting a clear, effective agreement in place.

What Should a Marketing Agency Agreement Cover?

A marketing agency agreement should clearly set out the services the agency will provide and the expected workload. This depends on the nature of the marketing campaign and may include a specified number of social media posts each week or month, a set number of hours for campaign management, a set number of marketing campaigns, content creation, or agreed SEO work.

The more specific the scope of work, the easier it is for both parties to understand what is included. For example, if an agency is responsible for social media management, the agreement could specify which platforms are covered, the number of posts to be produced, whether the agency will respond to comments and messages, and whether photography, video production or paid advertising is included. This can help avoid later disagreements about whether additional work falls within the agreed fee.

The agreement may also set out standards and requirements for the agency’s work. These may include deadlines, approval processes, brand guidelines, reporting requirements, or specific performance measures. Where appropriate, these provide an objective basis for assessing whether the agreed services have been delivered.

The parties may also discuss expected outcomes and performance targets. Some agencies may agree to work towards specific metrics, such as website traffic, leads, engagement or conversion rates. In some cases, an agency may offer a guarantee or contractual commitment for a particular level of performance. However, businesses should carefully consider what is actually being guaranteed. Marketing results can be affected by factors outside the agency’s control, including market conditions, advertising budgets, the client’s pricing and product offering, and changes to search engine or social media algorithms.

For this reason, an agreement will often focus on the services and work to be delivered, rather than guaranteeing a specific return on investment (ROI) or level of engagement. If performance targets are included, the agreement should explain how they will be measured and what will happen if they are not met.

Other provisions will typically address fees and expenses, payment terms, intellectual property, confidentiality, data protection, the client’s responsibilities and termination. The precise terms should reflect the services provided and the parties’ commercial relationship.

Legal Considerations for Marketing Agency Agreements in the UK

When entering into a marketing agency agreement, businesses should consider whether any legal requirements apply beyond the contract itself.

One issue to consider is the Commercial Agents Regulations 1993. The Regulations apply to certain self-employed commercial agents who have continuing authority to negotiate the sale or purchase of goods on behalf of a principal. They do not generally apply to businesses providing marketing services simply because those businesses are described as an “agency”. The Government confirmed in 2025 that the Regulations remain in force but that they do not cover services.

However, the position may differ if a marketing agency also acts as a commercial agent, for example, by having continuing authority to negotiate the sale or purchase of goods on the business’s behalf. Where the Regulations apply, they can provide commercial agents with additional rights, including statutory notice provisions and potential compensation or indemnity upon termination of the relationship.

The agreement should also clearly address exclusivity and territory. An exclusivity clause may require the business to use the agency exclusively for particular marketing services or prevent the agency from providing similar services to certain competitors. A territory clause can define the geographical area or market for which the agency is responsible.

These provisions should be carefully drafted. For example, an SME should understand whether it is prevented from appointing another agency for a particular campaign, or whether the agency is prohibited from working for all competitors or only named competitors. The duration of any restriction should also be clear.

Finally, businesses should consider termination rights and notice periods. The agreement should specify whether it is for a fixed term or continues until either party gives notice, how much notice is required and whether either party can terminate early for serious breach or another specified reason.

Common Risks and Disputes

Marketing agency relationships can work well, but disputes often arise when the agreement does not clearly set out each party’s obligations. Putting the key commercial arrangements in writing at the outset can help reduce this risk.

Breaches and Liability

A breach of contract may occur if either party fails to fulfil an obligation under the agreement. For example, an agency might fail to provide the agreed service or miss an important contractual deadline. Equally, the business might fail to pay the agency, provide information, or approve marketing materials when required.

The agreement should therefore clearly set out each party’s responsibilities and the consequences if those responsibilities are not met. Businesses should also pay close attention to liability provisions, particularly where a marketing campaign could entail significant expenditure or reputational risk.

For example, the parties may agree to limits on the agency’s liability, subject to any liabilities that cannot be excluded or limited by law. An SME should understand these provisions before signing, rather than discovering their effect only when something goes wrong.

Payment and Commission

Payment disputes can arise when an agreement does not clearly set out how the agency will be paid or when a fee or commission is due. The contract should state whether the agency receives a fixed fee, monthly retainer, project fee or commission, and, where commission applies, exactly how it is calculated.

Winlink Marketing Ltd v The Liverpool Football Club & Athletic Grounds Ltd is a useful example. The case concerned an introducer agreement under which commission was payable when contacts introduced by the claimant entered sponsorship deals. The court considered whether the introduction had to be an effective cause of the eventual purchase before commission became payable, and ultimately decided that in this case, the claim was unfounded.

The case highlights the importance of clear commission arrangements. If payment depends on an introduction, lead or sale, the agreement should explain what triggers entitlement to payment and address transactions that complete after the agency relationship has ended.

For a typical marketing agency, which may be paid a fixed fee rather than a commission, the practical lesson is straightforward: make the payment mechanism clear. The contract should leave as little room as possible for disagreement about what the agency is being paid for and when payment is due.

Exclusivity and Conflicts of Interest

Exclusivity can also create difficulties. A business may want an agency to work exclusively on its marketing, while the agency may want the freedom to work for other clients, including businesses in the same sector.

The agreement should therefore clearly define any exclusivity obligations. If an agency cannot work for competitors, the parties should consider whether “competitor” needs to be defined and whether the restriction applies to the whole business or only particular products, services or markets.

The parties should also consider conflicts of interest. An agency working for two businesses with competing interests may encounter situations where confidential information, campaign strategies or commercial knowledge could create a conflict. Clear contractual obligations on confidentiality and conflicts can help manage these risks.

Fixed-Term or Ongoing: Which Contract Structure?

Businesses should consider whether a marketing agency agreement should run for a fixed term or continue on an ongoing basis.

A fixed-term agreement can provide certainty for both sides. For example, a business may commit to a six- or twelve-month marketing campaign, giving the agency a defined period in which to plan and deliver the agreed work. This may also make sense where the agency is undertaking a substantial project or where both parties want to review the relationship at the end of a defined period.

However, a fixed-term arrangement can be less flexible. A business may remain committed to paying for the agreed period, even if its marketing priorities change, subject to the contract’s termination provisions.

An ongoing or rolling agreement can offer greater flexibility, as either party can usually end the relationship by giving the required notice. This may suit an SME whose marketing needs are likely to change over time. The trade-off is that the agency may have less certainty about the relationship’s duration.

No single structure suits every business. The key point is to ensure that the contract clearly explains how long it lasts, how it can be ended and what happens when it ends.

Legal Obligations of the Business and the Agency

Both parties should understand that their obligations do not end when the agency delivers marketing work.

The agency should provide the services agreed in the contract and comply with all applicable legal and regulatory requirements. Depending on the campaign, this may include requirements relating to advertising, consumer protection, intellectual property, data protection and the use of third-party content.

The business will usually need to provide the agency with accurate information, approvals, access to relevant accounts, and any other materials reasonably required to perform the services. It will also need to pay the agreed fees under the contract.

Marketing activity directed at consumers must comply with applicable consumer protection rules. The Digital Markets, Competition and Consumers Act 2024 introduced updated rules on unfair commercial practices, which have been in effect since 6 April 2025. These rules cover practices such as misleading consumers and certain practices involving fake reviews.

The contract should therefore, where appropriate, make clear who is responsible for approving advertising claims, obtaining permissions, and ensuring that content supplied by either party can be used legally.

Best Practices for Marketing Agency Agreements

A well-drafted marketing agency agreement should clarify roles and responsibilities while reflecting the specific services and commercial arrangements involved.

Clearly define roles and responsibilities

Set out what the agency will provide, what the business needs to provide and who is responsible for approvals, content, advertising budgets and other key tasks.

Set out the scope of work

Be specific about the services included, such as the number of posts, campaigns, hours or reports, and explain how additional work will be agreed and charged.

Agree fees and payment terms

State how the agency will be paid, when invoices are due and whether expenses, advertising spend or additional services are charged separately.

Address intellectual property

Clarify who owns content, designs, branding, photographs, videos and other materials created during the relationship, and what happens to these materials when the agreement ends.

Protect confidential information

The agreement should explain what information is confidential, how it can be used and whether confidentiality obligations continue after termination.

Consider data protection

Where the agency handles personal data on the business’s behalf, the agreement should reflect the parties’ responsibilities under applicable UK data protection law.

Check regulatory compliance

The parties should understand who is responsible for ensuring marketing activity complies with applicable UK laws and advertising rules. This can include requirements concerning misleading advertising, consumer protection, intellectual property and data protection.

Be clear about exclusivity and conflicts of interest

Any restrictions on the agency working for competitors should be clearly defined, including their scope and duration.

Include a clear dispute-resolution process

Consider requiring the parties to try to resolve disputes through discussions or mediation before starting court proceedings.

Agree clear termination arrangements

State how much notice is required, whether early termination is permitted and what happens to outstanding fees, unfinished work, marketing accounts and materials when the relationship ends.

Review the agreement regularly

Marketing strategies, technology, platforms and legal requirements can change. Review the agreement whenever the scope of work, fees, responsibilities, or relevant legal requirements change.

Key Takeaways for Businesses

A marketing agency agreement should clearly set out what the agency will deliver, what the business must provide, how performance will be measured, and what will happen if the relationship does not work as planned. Agreeing these points at the outset can help avoid misunderstandings and provide greater certainty over areas such as intellectual property, confidentiality, payment, exclusivity, and termination.

Where an agency arrangement goes beyond straightforward marketing services, businesses should also consider whether any additional legal requirements apply. Because marketing arrangements can vary considerably, the agreement should be tailored to the services provided and the business’s needs.
