We build content management systems that put your editorial team in control. If your editors are filing developer tickets just to update a headline, your CMS is holding you back.

Talk to us about your CMS

Off-the-shelf platforms start simple, then grow unwieldy. Plugin updates break layouts. Per-seat licensing inflates costs. Small content changes sit in a developer queue for days.

A custom CMS gives your editors interfaces shaped around real workflows: approval chains, scheduled publishing, brand-locked templates and a centralised asset library. The result is confidence in brand alignment when publishing at speed, without waiting on engineering. We handle custom software development and UX design together so the system feels intuitive and purpose driven from day one.

What does a custom CMS include?

  • Content & pages

    Editors your team will use

    We build intuitive page and content editors around how your team actually works. No developer tickets, no waiting. Hit publish and move on.

  • Digital assets

    One place for every file

    Upload, tag, crop and serve images and documents from a single library. Files stay organised and optimised for every channel you publish to.

  • Publishing workflows

    Draft, review, approve, schedule

    Role-based permissions keep the right people in the loop. Content moves from draft to live on a clear, auditable path. Your team stays in control throughout.

Why choose custom over off-the-shelf?

We build your CMS around how your team actually works, so editors publish without waiting on a developer. No plugin vulnerabilities to patch, no forced updates that break your site, no per-seat licensing that grows with your headcount.

Popular platforms are common targets for attacks. A custom build lowers your exposure because there's no public codebase to exploit.

  • No plugin security risks
  • Publish faster, no dev queue
  • Zero per-seat licensing fees
  • Built around your editorial workflow

What your custom CMS covers

Every CMS we build is shaped around your team's actual content operations. Here are five areas we address during discovery and delivery.

Multi-site and multi-language

Multi-site and multi-language

Run several brands, regions or language variants from one login.

  • A single backend manages every site, locale and brand you operate
  • Editors publish to the right audience without switching tools
  • You can add new sites or languages without rebuilding the platform

SEO and accessibility built in

Your editors shouldn't need a developer to get pages ranking or meeting WCAG standards.

  • Meta titles, descriptions and structured data are editable per page
  • WCAG-compliant markup is baked into every template
  • Automated checks flag issues before content goes live

Security and UK hosting

No shared plugin ecosystem means no shared attack surface.

  • Your CMS runs on its own infrastructure, not a shared target
  • We host in the UK so data stays within your compliance requirements
  • Patches and updates happen on your schedule, not a vendor's
Scalability from day one

Scalability from day one

Content libraries grow. Traffic spikes. Your CMS should handle both without re-platforming.

  • The architecture is designed to absorb rising content volume
  • Cloud-native scaling handles traffic spikes
  • There's no performance cliff as your editorial team or audience grows

Zero-downtime content migration

Moving away from your current CMS shouldn't mean lost content or broken URLs.

  • We map and migrate pages, media and metadata from your existing platform
  • URL redirects preserve your search rankings
  • Cutover is planned so your site stays live throughout

Built with your team

Every project starts with a documented discovery session before any code is written. We map user journeys, define your content model and scope every integration. That establishes scope early and avoids surprises once the build begins.

You get a dedicated project lead from our senior in-house team based in London and Belfast. The people in your discovery sessions are the same people building your CMS.

  • Discovery pack before code starts
  • Single named senior lead throughout
  • Same team from discovery to launch
  • UK timezone, direct team access

How does a CMS development project work?

Every milestone has a visible deliverable you approve.

  1. Discovery and Content Audit

    We map your content, users and integrations so the build starts from a clear, agreed brief.

  2. Content Modelling and UX

    We design the editorial experience: content types, roles and workflows your editors will actually use.

  3. Core CMS Build

    We build the CMS structure, permissions and content types in a focused first sprint.

  4. Integrations and Migration

    Existing content moves across. Publishing workflows go live. Third-party systems connect.

  5. QA, Training and Handover

    Your team learns the system hands-on before launch. We don't go live until you're confident.

  6. Launch and Ongoing Support

    Go live with our team behind you. Post-launch support is available so nothing stalls after day one.

  • Founded in London and Belfast

    We opened our doors in 2015 with a simple principle: the people you meet are the people who build your product. That has not changed.

  • In-house team, no subcontracting

    Every project is designed and built by our senior engineers and designers across both offices. No offshoring, no freelance layers. You work directly with the team doing the work.

  • Discovery-first from day one

    We run in-person discovery sessions at our own offices before writing a line of code. It keeps scope honest and means fewer surprises once the build starts.

  • Milestone delivery as standard

    We break every engagement into clear milestones with defined deliverables. You review and sign off progress at each stage rather than waiting for a single huge handover.

  • From startups to global brands

    Our client base ranges from early-stage founders to established enterprises across the UK, Europe and the US. The common thread is teams who need reliable, senior delivery.

  • CMS, apps, AI and bespoke software

    Content management is one part of a broader capability set spanning mobile apps, bespoke software and AI. That breadth means your CMS can grow and scale in functionality alongside the business.

CMS Costs, Timelines and Clarity

Scope drives cost. We map content types, roles and integrations in a discovery call, then quote milestone by milestone so nothing is hidden.

A focused CMS can ship within a couple of months. Larger multi-site builds typically take a quarter or more. Discovery pins down the timeline before any commitment.

Every milestone has a clear deliverable you can review before the next begins. You see value at each stage, not a single invoice at the end. Book a discovery call to get a scoped estimate.

  • Milestone-based pricing, no surprises
  • Discovery scopes before code starts
  • You approve each deliverable
  • Timelines tied to your complexity

Is a custom CMS for you?

We're not the right partner for every project. Here's how to tell if we're a good match.

A great fit

  • Your team logs developer tickets just to update content or publish pages
  • You've outgrown your current CMS and need something built around your workflows
  • You manage content across multiple brands, sites or languages
  • You want to own your platform, not rent features from a vendor
  • You value a discovery phase that scopes properly before any code is written

Not the right fit

  • You need a simple blog or brochure site. A standard platform will serve you well
  • You need a website live tomorrow. We run discovery first to get the build right
  • You're looking for the lowest price above all else
  • You want to hand off the project and check back in six months

FAQ

CMS development FAQs

Do I still need developers after a custom CMS is launched?

No. The whole point is independence. We build your CMS so editors can create, update and publish content without writing code. Your team handles day-to-day content operations, and we're here if you need changes to the system itself down the line.

Can you migrate content and media from our current CMS?

Yes. We map your existing content, assets and metadata during discovery, then handle the migration as part of the build. We validate everything before go-live so nothing is lost or broken in the move.

Will a custom CMS be SEO-friendly and accessible?

Absolutely. We build SEO controls (meta fields, structured URLs, sitemaps) directly into the editorial interface. Accessibility is baked in from the design phase, following WCAG guidelines so your published pages meet compliance requirements without extra effort from editors.

Can the CMS support multiple sites, languages or brands?

Yes. A custom CMS can be architected for multi-site, multi-language or multi-brand use from the start. Shared content models keep things consistent, while each site or locale gets its own publishing controls and permissions.

What post-launch support and training do you offer?

We run hands-on training sessions with your editorial team before handover. After launch, we provide a support period to fix any issues and answer questions. Ongoing support arrangements can be discussed based on your needs.

How is a custom CMS more secure than WordPress?

WordPress is a public codebase with thousands of third-party plugins, each a potential vulnerability. A custom CMS has a smaller, purpose-built attack surface with no public plugins. We host on infrastructure that meets UK data-protection requirements, and only your team has access.
