Notion vs Confluence: Which Knowledge Base Tool Should UK Businesses Use?

As UK businesses grow, the problem of organisational knowledge becomes increasingly acute. Processes that lived in one person’s head, onboarding steps that were passed on verbally, and client-facing documentation that was written once and never updated all become liabilities as teams expand, staff turn over, and clients expect more polished interactions. A knowledge base tool — a structured, searchable repository of documentation, processes, guides, and reference material — is how growing businesses solve this problem. Notion and Confluence are the two platforms most commonly evaluated by UK businesses and agencies when making this investment.

The comparison between Notion and Confluence is interesting because the two tools have converged in some areas while remaining genuinely different in others. Notion started as a flexible all-in-one workspace — part notes app, part wiki, part database, part project manager — and has grown into a tool used by everyone from individual freelancers to mid-sized companies managing their entire operational documentation in one place. Confluence started as an enterprise wiki, built specifically for software development teams to document technical decisions, runbooks, and product specifications alongside Jira. Understanding which problem each tool is optimised to solve is the key to making the right choice for your specific context.

Flexibility, design, and all-in-one workspace capability

Notion’s defining quality is its flexibility. A Notion workspace can contain structured databases with custom properties, free-form pages with rich text and embeds, kanban boards, calendar views, and filtered gallery views — and all of these can be mixed and linked within a single page structure. This flexibility means Notion can serve as a company wiki, a project tracker, a CRM, a content calendar, and a client portal simultaneously, all within a single shared environment. For small to medium UK businesses that want to consolidate their operational tools rather than paying for separate subscriptions for documentation, project management, and database functionality, Notion’s breadth is a compelling proposition. Its design aesthetic is clean and contemporary, and documents produced in Notion look professional without requiring any formatting effort.

The same flexibility that makes Notion powerful for diverse use cases also makes it harder to govern as a team grows. Without clear page hierarchy conventions and regular maintenance, large Notion workspaces can become disorganised and difficult to navigate. Information can end up in unexpected places, pages can be duplicated without being linked, and search across a large Notion workspace is less reliable than in a more structured tool. For teams that invest time in maintaining their workspace structure — setting naming conventions, maintaining a clear page hierarchy, and regularly archiving outdated content — Notion works extremely well. For teams that need documentation to remain structured and findable without ongoing maintenance effort, a more opinionated tool like Confluence offers a more durable solution.

Jira integration, development teams, and enterprise structure

Confluence’s strongest use case is as the documentation layer for software development teams working in the Atlassian ecosystem. If your engineering team uses Jira for sprint planning, bug tracking, and roadmap management, the native integration between Jira and Confluence is genuinely valuable: Jira issues can be linked directly to Confluence pages, product requirements documents reference the sprints and stories that implement them, and post-incident reviews in Confluence link to the Jira tickets that tracked the resolution. This bidirectional linkage between tasks and documentation is difficult to replicate in Notion without significant manual effort and external integrations. For UK technology companies, digital product teams, and software agencies where Jira is the project management standard, Confluence is the natural documentation companion.

Confluence is also better suited to larger teams that need documentation governance. Its permission model is more granular than Notion’s — you can control who can view, comment on, or edit individual pages, spaces, or sections with precision. Confluence’s space structure (a top-level container for related pages) maps naturally onto organisational structure: an IT team space, a marketing space, an HR space, each with their own permissions and page templates. Confluence page templates for common document types — meeting notes, project kickoff documents, technical specifications, incident reports — provide structure that guides contributors towards consistent documentation without needing to enforce conventions manually. For UK agencies working on multiple client engagements simultaneously, Confluence’s space-per-client model with controlled permissions is a robust and auditable way to manage client-facing and internal documentation side by side.

Pricing, public vs. internal documentation, and linking to your website

Notion’s free plan covers personal use and small teams with unlimited pages and basic features, though AI features and advanced permissions require paid plans. Notion Plus costs £9 per user per month, with Business at £14 per user per month adding advanced permissions, SAML SSO, and audit logs. Confluence’s free plan covers up to 10 users with 2GB storage, making it the most generous free tier for small development teams. Confluence Standard is around £4.89 per user per month and Premium around £8.15 per user per month — both competitively priced compared to Notion, particularly for larger teams where per-user pricing compounds quickly. For UK agencies evaluating cost at scale, Confluence’s lower per-user price at comparable feature levels is a meaningful consideration.

One dimension that increasingly matters for UK businesses is whether their knowledge base content should be public or internal — and how it connects to their website. A growing number of UK businesses publish parts of their documentation publicly: help centres, product guides, FAQ pages, and support articles that their clients and prospects can access without logging in. Notion has a simple publish-to-web feature that makes any page publicly accessible via a unique URL, which is a quick way to share documentation externally without building a dedicated help centre. However, for businesses that want their public documentation to feel like a natural part of their website — matching their branding, appearing in their website’s navigation, and being indexed properly by search engines — a published Notion page is a stopgap rather than a solution. At Xpose in Norwich we regularly help UK businesses think through the distinction between internal knowledge management tools and public-facing documentation that belongs on or alongside their website. Notion and Confluence both serve the internal use case well; neither is a substitute for a properly built, SEO-optimised help centre or documentation section integrated into your website. If your documentation is customer-facing and strategically important, it deserves to live on your own domain rather than on a third-party platform’s subdomain.

Our view on Notion vs Confluence

We are a Norwich agency established in 2015, and we have worked with businesses on both sides of this comparison over the years. Our honest view: the right choice depends on your business, your team and where you want to be in two years — not on which platform is currently the most talked-about.
