2. About this website

This website provides general information about 5sum, its positioning, capabilities, work, insights, publications, Project Enquiry route, careers and talent-network routes.

5sum is a UK-headquartered, remote-first, design-led consultancy-studio for brand, digital experience, product and growth. The website is designed to help business and professional audiences understand what 5sum does, how work is scoped, what kind of proof or work samples are available, and how a suitable Project Enquiry may begin.

The website is an information and enquiry route only. It does not replace a proposal, statement of work, master services agreement, confidentiality agreement, employment contract, contractor agreement, supplier agreement or any other formal written arrangement that may apply to a specific relationship.

3. Capability information and availability

The website may describe 5sum’s capabilities across Strategy & Proposition, Brand & Creative Systems, Digital Experience & Product, Campaigns, Content & Demand, and Growth Intelligence & Optimisation.

Descriptions of capabilities, project routes, outputs, diagnostics, audits, work samples, case stories, concepts, archive items, articles or other materials are provided for general information. The availability, timing, scope, fee, team, specialist support and commercial terms of any specific project depend on separate review and written agreement.

Submitting a Project Enquiry does not guarantee that 5sum will accept the work, provide a proposal, schedule a call, begin an engagement or provide advice. 5sum may recommend clarification, a diagnostic or scoping phase, a scoped project, a staged programme, a referral, a nurture route or no further action, depending on fit, capacity, timing, budget range, risk and written context.

4. Public website content is general information

Content published on the website is provided for general business, marketing, design, digital experience, publication and company information only. It should not be treated as advice tailored to any particular

organisation, project, product, campaign, transaction, legal issue, financial matter, regulatory issue, employment issue or operational decision.

Insights, reports, teardowns, field notes, work stories and archive items may describe methods, frameworks, examples or observations. They are not a substitute for a proper diagnostic, audit, project scope, legal review, financial advice or other professional assessment of a specific situation.

Readers remain responsible for deciding whether any website content is relevant to their circumstances and whether separate professional advice is required before taking or refraining from action.

5. Specialist and regulated matters

Nothing on this website constitutes legal, tax, accounting, audit, investment, financial, insurance, immigration, employment-law, medical, security or other specialist regulated advice.

Where a matter requires input from a suitably qualified or regulated professional, you should obtain independent advice from an appropriate adviser.

This distinction does not prevent 5sum from providing lawful strategic, brand, digital experience, design, content, campaign, optimisation or related consultancy-studio services within the scope of its business and under appropriate written terms.

6. No offer, solicitation or financial promotion

Nothing on the website constitutes or is intended to constitute an offer to sell or issue shares, securities or other investments; an invitation or inducement to invest; a regulated financial promotion; investment advice; a recommendation in relation to any transaction, financing arrangement, security, investment, fund, regulated activity or financial product; or a binding proposal, commitment or representation by 5sum.

References to sectors, commercial problems, company direction, capabilities, work examples, publications, careers, partnerships or possible project routes are general descriptions unless formal written documentation expressly states otherwise.

7. No relationship created by website use

Accessing the website, reading content, downloading materials, submitting a Project Enquiry, sending a message, uploading an attachment, subscribing to a newsletter, applying for a role, joining the talent network or beginning an initial conversation does not by itself create a client relationship, consultancy relationship, advisory relationship, fiduciary relationship, employment relationship, contractor relationship, partnership, joint venture or any other formal legal relationship with 5sum.

A formal relationship arises only where the relevant parties agree appropriate written terms or other formal written arrangements.

8. Project Enquiries, forms and attachments

Website forms and contact routes are intended to support appropriate first contact and efficient review. They should not be used to send full confidential briefs, privileged material, commercially sensitive documentation, personal data that is not necessary, restricted information or highly sensitive material unless an appropriate basis for sharing it has already been agreed.

Where the website allows file uploads, users should submit only materials reasonably necessary for the relevant enquiry, role, talent-network route or process. 5sum may decide not to open, review, retain or respond to attachments that appear unsafe, excessive, irrelevant, unlawful, confidential without an agreed basis or inconsistent with the intended purpose of the form.

More information is provided in the Project Enquiry and Contact Route Notices, Privacy Policy and Careers and Talent Network Privacy Notice.

9. Accuracy, completeness and updates

5sum aims to present website content clearly and carefully. However, website content may be updated, refined, corrected, withdrawn, reorganised or expanded from time to time as the company, website, proof base, publications, services, legal requirements or operating model develop.

No representation, warranty or guarantee is given that every item of website content will always be complete, current, uninterrupted, error-free or suitable for every reader’s circumstances. 5sum may update or withdraw pages, features, forms, articles, archive items, policy documents or website materials without prior notice.

10. Work samples, case studies, proof and archive materials

The website may include work samples, case studies, work stories, anonymised work, concepts, process artefacts, internal explorations, archive items or other forms of proof.

Where proof materials are made available, 5sum aims to label them accurately. A work sample should not be assumed to be a full case study; a concept should not be assumed to be client work; and a process artefact may have confidential details removed or anonymised. Metrics, outcomes, client names, testimonials and performance claims should be treated as published only where the relevant material expressly states that they have been approved and evidenced.

Do not rely on a visual example, archive tile or article as evidence of a particular result unless the page expressly states the relevant context and evidence.

11. Intellectual property and website materials

Unless otherwise stated, all rights in the website and its content are owned by, licensed to or otherwise controlled by 5sum. This includes website wording, structure, layout, design treatment, graphics, branding, logos, trade names, page architecture, written materials, policy materials, articles, reports, archive presentation and other content made available through the website.

You may view the website and print or download limited extracts for lawful internal reference. You must not copy, reproduce, scrape, republish, frame, adapt, translate, distribute, license, sell, commercially exploit or otherwise use website content without prior written permission, except to the extent permitted by law.

Nothing on the website grants any licence or right to use the 5sum name, logo, trade marks, design elements, written content, visual style or other intellectual property.

12. Third-party names, links and materials

The website may refer or link to third-party platforms, tools, websites, services, publications, technologies, social channels or resources. Third-party names, marks and references are used for identification, context, supplier, operational, publication or informational purposes only. They do not imply endorsement, partnership, approval, sponsorship or responsibility unless expressly stated.

Third-party resources are outside 5sum’s control. 5sum is not responsible for third-party content, policies, privacy practices, security, availability, accuracy, functionality or the consequences of relying on material found on external sites.

13. Website availability and security

5sum may update, suspend, restrict, withdraw, reorganise or change any part of the website at any time. No representation is given that the website, any page, any form, any document or any contact route will remain available indefinitely or without interruption.

5sum may take technical, security, operational, legal or editorial steps where appropriate to protect the website, manage traffic, prevent misuse, preserve system integrity, investigate security issues, maintain content quality or comply with legal requirements.

14. Website policies

This Legal Notice and Company Information page should be read together with the website’s other public policies and notices, including the Terms of Use, Privacy Policy, Cookie Policy, Project Enquiry and Contact Route Notices, Careers and Talent Network Privacy Notice, Newsletter and Publication Subscription Notice, Website Accessibility Statement and Responsible Business, CSR and ESG Statement where relevant.

15. Governing law and jurisdiction

This Legal Notice and Company Information page, and any non-contractual matters arising out of or in connection with it, are governed by the laws of England and Wales. The courts of England and Wales shall have exclusive jurisdiction, except where mandatory law provides otherwise.
