How to Write a Brand Guidelines Document

A clear, consistent brand is vital for any UK small business that wants to stand out, build trust, and grow. But how do you actually put your brand’s rules and personality down on paper so they’re usable by staff, designers, and partners? This guide walks you through every aspect of writing practical, professional brand guidelines—what to include, how detailed to be, and how to make sure your document actually gets used. We’ll cover the must-have sections, UK legal considerations, and common mistakes to avoid, so you can protect your brand’s identity from day one.

Brand guidelines are far more than a design manual—they’re the single source of truth for how your business presents itself to the world. For UK small businesses, they help ensure consistency across every touchpoint, from social media to invoices, no matter who’s creating the content. This consistency is crucial for building recognition in a crowded market, especially when you’re competing with bigger players.

Without clear guidelines, even well-meaning staff or freelancers can easily dilute or damage your brand. Consider how a misused logo, inconsistent colours, or an off-message tone of voice can undermine your credibility. In the UK, where consumers are quick to judge professionalism, even small slips can cost you business.

Brand guidelines also make onboarding easier, speed up design and marketing processes, and significantly reduce the risk of expensive rework. They’re essential for protecting your intellectual property, especially if you outsource design work or collaborate with external partners. Comprehensive guidelines are not just for large corporates; they’re a practical, cost-saving tool for every ambitious UK small business.

A robust brand guidelines document covers much more than just logos and colours. At a minimum, it should explain your brand’s core identity, visual assets, and tone of voice. However, the best guidelines go further—covering practical usage, legal considerations, and digital assets relevant to the UK market.

When deciding what to include, always tailor the detail to your business’s needs and future plans. If you plan to grow or use external teams, more detail is better. For UK businesses, it’s also important to reference relevant standards (like accessibility or copyright law) and practicalities such as .uk domain usage, social media handles, and UK spelling conventions.

Below is a standard structure for UK small business brand guidelines. You can adapt this list to suit your sector, but don’t skip the essentials. Each section should be clear, specific, and illustrated where possible.

• Brand story (mission, vision, values, and positioning statement)
• Logo usage (primary, secondary, spacing, and incorrect uses)
• Colour palette (including RGB/CMYK/HEX codes for digital and print)
• Typography (fonts, sizes, weights, and hierarchy)
• Imagery style (photography, graphics, icons, and illustrations)
• Tone of voice and messaging (including UK spelling and grammar rules)
• Digital application (website, social media, and email signatures)
• Stationery and print collateral (business cards, letterheads, invoices)
• Legal and copyright guidance (trademark usage, third-party assets)
• Accessibility requirements (colour contrast, font legibility, alt text)

Your brand identity is the foundation of your guidelines. This section isn’t just marketing fluff—done right, it provides a reference point for every design and communication decision. Start with a concise statement of your business’s mission (why you exist), vision (where you’re going), and values (what you stand for). These should be genuinely meaningful to your team and customers, not generic platitudes.

Next, outline your brand personality. Are you friendly and informal, or formal and authoritative? Are you rooted in local community, or aiming for nationwide reach? Use clear, UK-relevant language, and give real examples (e.g. 'We avoid Americanisms like “color” or “favorite”.' or 'We reference UK pop culture, not US trends.').

Finally, include your brand’s positioning—who you serve, what makes you different, and the promise you make to your customers. This is especially important in the UK market, where subtle differences (such as being 'British-made' or supporting local causes) can strongly influence buying decisions.

• Keep descriptions specific—avoid buzzwords and clichés
• Tie values to real business practices (e.g. sustainability, fair pay)
• Include practical examples of your tone and messaging in action
• Clarify what you are NOT as well as what you are (e.g. 'We’re never sarcastic')
• Use customer quotes or testimonials to reinforce your brand personality

Your logo is often the first thing people notice about your business. It’s vital to set out exactly how it should (and shouldn’t) be used. This section should include high-resolution versions of your logo, in all approved colourways and file types (SVG, PNG, JPEG), and specific instructions on placement, sizing, and clear space. In the UK, where print and digital materials vary widely, include both RGB (digital) and CMYK (print) colour specifications.

Be explicit about what’s not allowed: stretching, recolouring, adding effects, or changing the logo’s proportions. Provide visual examples of correct and incorrect uses. Make sure to include guidance for third-parties, such as local press or event partners, so your logo isn’t misrepresented in the media.

If your logo includes a trademark or registered symbol, clarify its correct usage. In the UK, the Intellectual Property Office (IPO) governs trademarks. State whether your mark is registered or pending, and always include the correct ® or ™ symbol as appropriate. This isn’t just about looking professional—it’s about protecting your business legally. Registering Your Logo as a Trademark

• Specify minimum size for legibility (e.g. 30mm for print)
• Show logo placement on dark and light backgrounds
• Include a download link or appendix with approved logo files
• List any restrictions on use by third parties or partners

Colour and typography are major contributors to your brand’s recognisability. In your guidelines, specify the exact colours (with HEX, RGB, and CMYK values) for digital and print use. Include primary and secondary palettes, and explain when and how to use each. For UK businesses, remember that print standards can vary—always test colours with your local printer to avoid surprises.

For typography, list the main fonts your brand uses. Specify font families, weights (bold, regular), sizes, and hierarchy (e.g. headings, subheadings, body copy). If you use licensed fonts, state where to download them, along with any licensing restrictions. Instruct on acceptable substitutes for situations where your preferred font isn’t available (such as on Google Workspace or Office 365). Why Typography Matters for Your Business Identity

Don’t overlook accessibility. In the UK, the Equality Act 2010 makes it a legal requirement to ensure your communications are accessible to disabled people. Specify minimum font sizes, acceptable colour contrasts, and avoid using colour alone to convey meaning. This isn’t just good practice—it can protect you from legal complaints and broaden your audience.

• Include a visual swatch for each colour in your palette
• List acceptable and unacceptable font pairings
• Provide web-safe fallback fonts for digital use
• Explain when to use bold, italics, and underlining (if at all)
• Reference the latest Web Content Accessibility Guidelines (WCAG) for contrast ratios

Your tone of voice is as much a part of your brand as your logo. In this section, describe how your business communicates in writing—whether on your website, in emails, or on social media. Are you friendly and conversational, or more formal and business-like? Give clear, UK-relevant examples, using real phrases your business would (or would never) use.

Specify grammar, spelling, and punctuation conventions—UK English only (colour, organise, licence), no Americanisms, and always use the serial comma if that’s your preference. Clarify how to handle common UK quirks, such as writing dates (day/month/year), using £ instead of ‘GBP’, and referencing local places or events.

Provide do’s and don’ts, sample email sign-offs, and approved taglines or slogans. If your business has specific policies on inclusive language or avoids jargon, spell these out. This section should leave anyone—internal or external—fully equipped to write on your behalf without risking a PR disaster.

• List approved greetings and sign-offs for emails and letters
• Clarify when (and when not) to use humour or slang
• Show examples of brand messaging in action (website, ads, social posts)
• Provide a glossary of key terms unique to your business or sector
• State a policy on emojis and exclamation marks (useful for social media)

Images, icons, and illustrations all contribute to your brand’s visual language. Use this section to define your preferred image style: bright and natural photography, quirky illustrations, formal headshots, or something else. State which types of imagery are on-brand, and which should be avoided (e.g. 'No US stock photos', 'No clip art').

For icons and graphics, be clear about style, colours, and usage. Specify whether icons should be outline or solid, what colours to use, and where to source approved icons. For UK businesses, it’s also wise to clarify rules about using images of people—consider diversity, inclusion, and GDPR (General Data Protection Regulation) implications for staff or customer photos.

Don’t forget to address copyright and licensing. Only use images you own or have licensed for commercial use in the UK. Provide guidance on sourcing images (e.g. UK-based stock libraries, in-house photos) and always require attribution if needed. This avoids legal headaches and keeps your marketing compliant.

• State minimum resolution for print and digital images
• List preferred aspect ratios for website and social media
• Clarify requirements for image credits or attributions
• Include a contact for image rights queries (internal or legal)
• Explain how to request new imagery that fits brand guidelines

Your brand guidelines should make it easy for anyone to apply your brand rules across every platform. Dedicate sections to digital (website, email, social media), print (stationery, signage, packaging), and any other unique touchpoints relevant to your business. For each, show real examples and specify any platform-specific tweaks (e.g. how your logo should appear as a LinkedIn avatar vs. a letterhead).

In the UK, platforms like LinkedIn, Facebook, Instagram, and X (formerly Twitter) are all widely used by small businesses. Clarify the correct use of social media handles (e.g. @yourbusinessUK), profile images, cover photos, and bio text. Provide templates or download links for common assets like email signatures, invoice headers, and PowerPoint slides.

Don’t forget legal and accessibility must-haves. For print, include guidance on using the correct UK address format, registered company number (if a limited company), and VAT number where required. For digital, specify alt text for images, accessible PDF exports, and GDPR-compliant use of personal data in marketing materials.

• Provide pixel dimensions for profile images and social banners
• Show sample business card and letterhead layouts
• List all approved social media account names and URLs
• Include instructions for setting up branded email signatures in Office 365/Gmail
• Clarify guidance for using brand assets in video or audio formats

Brand guidelines aren’t just about aesthetics—they must also keep your business compliant. In the UK, copyright, trademark, and data protection laws affect how you create and share brand assets. Clearly state who owns your brand assets (usually your company) and restrict their use to authorised parties only. If you use freelancers or agencies, ensure contracts assign copyright to your business.

Include a section on trademark usage. If your name or logo is registered with the UK Intellectual Property Office, spell out how and when to use the ® symbol. For unregistered marks, use ™ but clarify the limits of protection. If you provide brand assets to third parties (such as partners or press), require written permission for edits or unusual uses.

Address accessibility and GDPR. Under the Equality Act 2010, all your communications must be accessible to disabled people. Spell out requirements for font legibility, alternative text for images, and accessible formats for PDFs and websites. For data protection, specify that all customer or staff images used in marketing must have explicit, GDPR-compliant consent.

• List all registered trademarks and their relevant classes
• Provide a copyright statement for inclusion on branded materials
• Clarify who to contact within your business for rights or usage queries
• Include a policy on archiving and retiring old brand assets
• Reference key UK laws: Copyright, Designs and Patents Act 1988, Equality Act 2010, GDPR

Writing brand guidelines isn’t a one-off design task—it’s a practical business process. Approach it methodically to ensure your document is genuinely useful and gets adopted by your team. Below is a practical, UK-focused step-by-step process.

• Schedule an annual review of your brand guidelines
• Keep a change log for any major updates
• Store master assets in a secure, cloud-based folder (e.g. Google Drive, OneDrive)
• Restrict editing rights to protect from accidental changes
• Encourage feedback and suggestions from all users
