What is Drupal
The enterprise CMS for genuinely complex requirements.
Starting from
£6,000
Flat quote · No prepayment · 6–14 wk delivery
Drupal is an enterprise-grade open-source CMS trusted by NASA, the BBC, and NHS Digital. WebAnts is a London Drupal agency building and migrating custom Drupal websites for enterprise organisations, government and public sector bodies, healthcare organisations, and large media and publishing platforms.
Unlike WordPress, Drupal handles genuinely complex content models — complex taxonomy, nested references, multi-vocabulary hierarchies — without hitting a schema ceiling. Its dedicated SA-CORE security team and built-in JSON:API make it equally capable as a traditional CMS or a headless backend.
We handle Drupal 7 to Drupal 10/11 migrations, headless Drupal with Next.js, multilingual and multisite builds, and WCAG 2.2 accessibility audits. Flat written quote after a free 30-minute discovery call.
Why Drupal
Six reasons enterprise organisations choose Drupal.
Complex content models. Enterprise permissions. Native multilingual. JSON:API built in. WCAG 2.2 by design.
01
Handles genuinely complex taxonomy and content relationships
Drupal's entity system supports any content type, field, and relationship structure. Complex taxonomies, nested references, multi-vocabulary hierarchies — no CMS handles genuine content complexity as cleanly as Drupal at scale.
02
Enterprise-grade permissions and workflow
Granular role and permission system with per-entity and per-field access control. Custom editorial workflows, content moderation states, and multi-team publishing pipelines — without third-party plugins.
03
Native multilingual — not a plugin
Drupal's multilingual support is built into core — language negotiation, content translation, RTL support, and locale-aware URL structures. No WPML, no Polylang, no plugin dependency for enterprise-level i18n.
04
JSON:API and GraphQL for headless/decoupled
Drupal ships with JSON:API built into core — no configuration required. A GraphQL module extends this further. Use Drupal as a structured content backend for Next.js, React, Vue, or any other frontend.
05
Powers the White House, NASA, BBC — proven at scale
Drupal runs some of the largest and most complex websites on earth. Its dedicated SA-CORE security team, enterprise-grade caching, and modular architecture make it the trusted choice for regulated organisations.
06
WCAG 2.2 accessibility by design — essential for public sector
Drupal core follows accessibility best practices. For public sector, NHS, higher education, and regulated organisations with WCAG 2.2 AA obligations, Drupal provides the right starting point — not a retrofit.
What we build
12 Drupal services.
From a Drupal 11 greenfield build to a Drupal 7 migration, headless architecture, or an accessibility audit — all delivered in-house in London.
01
Custom Drupal 10 / 11 Development

02
Drupal Headless (JSON:API / GraphQL + Next.js)
Drupal's built-in JSON:API or optional GraphQL module as a structured backend, Next.js App Router as the decoupled frontend. Preview API, on-demand ISR, TypeScript throughout — maximum performance without losing Drupal's editorial power.
03

Platform comparison
Drupal vs the alternatives.
We build on multiple CMS platforms. Here is an honest four-way comparison — WordPress, Umbraco, Contentful, Sitecore — so you can make the right call.
| vs Platform | Drupal wins on | They win on | Choose Drupal when |
|---|---|---|---|
| WordPress | Complex content modelling, granular permissions, native multilingual, SA-CORE security team, proven at enterprise and government scale | Lower cost and faster delivery for most SMEs, larger developer pool, simpler editorial experience, WooCommerce for ecommerce | You need complex content relationships, per-entity permissions, multilingual without plugins, or a security posture that meets government standards |
| Umbraco | Larger global community, more mature multilingual support, broader contrib module ecosystem, stronger government and public sector track record | .NET stack integration, familiar for Microsoft-led organisations, strong in UK digital agencies, smoother for small-to-mid enterprise | Your organisation is outside the Microsoft ecosystem, needs a larger contrib module library, or has public sector procurement requirements |
| Contentful | Self-hosted, no per-seat SaaS fees, full editorial UI, better for complex content models, JSON:API built into core, no headless tax | Polished developer experience, faster initial setup, SaaS convenience with no infrastructure management, cleaner for simple content models | You need complex content relationships, full data sovereignty, an editorial UI alongside the API, or Contentful pricing is scaling badly |
| Sitecore | Open source (no licence cost), comparable enterprise features, larger global community, lower total cost of ownership, no vendor lock-in | Microsoft stack DXP with CDP and personalisation built in, better for organisations already invested in the Sitecore ecosystem | Your organisation wants enterprise-grade features without Sitecore licence fees, or is not committed to the Microsoft ecosystem |

FAQ
Drupal questions, answered directly.
What is Drupal?
Drupal is an open-source CMS used by NASA, the BBC, the White House, NHS Digital, and some of the largest digital platforms on earth. It handles complex content models, granular permissions, native multilingual content, and enterprise-scale traffic. Drupal ships with JSON:API built into core, making it a full Digital Experience Platform (DXP) usable as a headless backend for any frontend technology. WebAnts is a London Drupal agency building custom Drupal 10 and Drupal 11 websites for enterprise, government, media, and regulated organisations.
How much does Drupal development cost in London?
A custom Drupal 10 or 11 site from WebAnts starts from £6,000 for a straightforward site with standard content types and a custom theme. A full build with multilingual, CRM integration, and WCAG compliance typically costs £12,000–£26,000. Headless Drupal with multisite and ERP integration costs £26,000–£48,000. Government and enterprise platforms with Drupal 7 migrations start from £48,000. Every project gets a flat written quote after a free 30-minute discovery call — no hourly estimates, no deposit.
What is the difference between Drupal and WordPress?
Choose Drupal if you need: complex content models with many custom entity types, granular user permission systems, robust multilingual support without plugins, or a security posture that meets government and enterprise standards. Choose WordPress if you need: lower total cost, faster time to launch, a larger developer pool, or a simpler editorial experience for non-technical teams. Most government bodies, universities, healthcare organisations, and large publishers choose Drupal. Most SMEs, agencies, and marketing-led businesses choose WordPress. WebAnts builds both and will advise honestly which fits your situation.
Is Drupal good for enterprise?
Yes. Drupal is one of the most trusted enterprise CMS platforms in the world. Its granular permission system, complex content modelling, native multilingual, JSON:API for headless architecture, and dedicated SA-CORE security team make it the correct choice for organisations with complex requirements. It handles millions of nodes, hundreds of content types, enterprise traffic, and multi-team editorial workflows at a scale no other open-source CMS matches.
Drupal vs WordPress — which should I choose?
Choose Drupal for complex content models, granular permissions, multilingual without plugins, or government/enterprise security requirements. Choose WordPress for lower cost, faster delivery, a simpler editorial experience, or if WooCommerce is needed for ecommerce. WebAnts builds both. We'll tell you honestly on the discovery call which is the right tool for your project — we don't recommend Drupal for every project because it only makes sense when the complexity genuinely requires it.
Drupal vs Umbraco — what is the difference?
Drupal is built on PHP and has a larger global community, more mature multilingual support, and a stronger track record in government and public sector. Umbraco is built on .NET (C#) and is well-suited for organisations in the Microsoft ecosystem. Both are enterprise-grade. Choose Drupal if you're outside the Microsoft stack, need a broader contrib module library, or have public sector procurement requirements favoring open-source PHP. Choose Umbraco if your developers are .NET-first.
What is Drupal headless?
Headless Drupal uses Drupal as a structured content management backend — accessed via its built-in JSON:API or the optional GraphQL module — while a separate frontend handles the user interface. You keep Drupal's powerful content model and editorial tools while gaining a modern, high-performance frontend (Next.js, React, Vue). We recommend headless for organisations with strict performance requirements, multiple frontend channels, or teams with strong JavaScript skills.
What is Drupal JSON:API?
Drupal's JSON:API module is built into Drupal core (since Drupal 8.7). It exposes all Drupal entities (nodes, taxonomy terms, users, media, and custom entities) as REST resources following the JSON:API specification. A Next.js frontend can fetch content from Drupal via JSON:API at build time (SSG/ISR) or runtime (SSR), giving you Drupal's editorial power with a modern, high-performance frontend.
Can Drupal handle multilingual content?
Yes. Multilingual support is built into Drupal core with four dedicated modules — Language, Content Translation, Configuration Translation, and Interface Translation. You define your languages, enable translation per content type and field, configure language negotiation (URL prefix, domain, cookie), and manage translated content from the standard Drupal admin. No plugin required — this is enterprise-grade i18n built in.
Can Drupal handle multisite?
Yes. Drupal's multisite capability allows a single codebase and database structure to power multiple domains or sub-sites, each with its own theme, content, and configuration. We use the Domain Access module for most multisite setups. Typical use cases include university faculty sites, local authority microsites, and enterprise regional sites. We scope and build multisite architectures for organisations managing 5 to 50+ sites from a single Drupal instance.
What is Drupal 10 / Drupal 11?
Drupal 10 is the current long-term support version, supported until January 2026. Drupal 11 was released in October 2024 and is the recommended version for all new builds — it requires PHP 8.3+, introduces Recipes for composable site configuration, adopts Single Directory Components (SDC) for frontend theming, and removes all deprecated Drupal 9 and 10 APIs. WebAnts builds new projects on Drupal 11 by default.
How do you migrate from Drupal 7 to Drupal 10?
Drupal 7 to Drupal 10/11 migration involves: module compatibility assessment (identifying which contrib modules have D10/11 releases and which need rewrites), custom module rewrites to match Drupal 10/11 APIs, content migration using Drupal's Migrate API (preserving all content relationships and taxonomy references), a parallel staging environment for UAT, and a zero-downtime production cutover. We scope every D7 upgrade individually — complexity varies significantly based on module count and custom code.
Is Drupal WCAG 2.2 compliant?
Drupal core follows accessibility best practices and the Drupal project maintains WCAG 2.1 AA compliance for core components. WCAG 2.2 AA compliance requires an audit of your specific theme, custom components, and editorial content — which we provide as a dedicated service including Axe, WAVE, and manual screen reader testing (NVDA, VoiceOver, JAWS). We deliver a written audit report with a prioritised remediation roadmap for public sector and regulated clients.
What is Acquia Cloud for Drupal?
Acquia Cloud is the leading managed Drupal hosting platform — built by the company founded by Drupal's creator, Dries Buytaert. It provides excellent performance, built-in security scanning, Cloud IDE, CI/CD pipelines, and multidev environments for teams. It's the preferred enterprise Drupal hosting choice for government, NHS, and large organisations. WebAnts configures and manages Acquia Cloud deployments as part of our Drupal delivery.
Is Drupal good for SEO?
Yes. Drupal generates clean semantic HTML, supports custom meta tags per content type, auto-generates XML sitemaps, handles canonical tags and hreflang for multilingual sites, and loads efficiently with BigPipe, Dynamic Page Cache, and CDN configuration. We configure JSON-LD structured data, Open Graph tags, robots.txt, and 301 redirects as standard on every Drupal build. Drupal's Views module enables powerful SEO-friendly content listing pages.
Can Drupal handle a large content archive?
Yes. Drupal handles millions of nodes across hundreds of content types. Large publishers, universities, and government bodies run content archives of this scale on Drupal regularly. Performance at scale requires proper caching configuration — BigPipe, Internal Page Cache, Dynamic Page Cache, Varnish reverse proxy, Redis, and CDN setup. We configure all of this as part of Scale and Enterprise builds.
How long does a Drupal project take?
A standard Drupal 10/11 site with custom content types and theme takes 4–7 weeks. A full build with multilingual, integrations, and WCAG compliance takes 7–12 weeks. Headless Drupal with multisite and ERP integration takes 12–18 weeks. Drupal 7 to 10/11 upgrade projects take 6–16 weeks depending on module complexity. We agree a firm timeline in the proposal and deliver weekly staging updates throughout.
What is Drupal Views?
Drupal Views is one of the most powerful modules in the Drupal ecosystem — a visual query builder that creates pages, blocks, feeds, and listings from any Drupal entity without writing PHP. You define which content types to show, what fields to display, how to filter and sort, and Views generates the SQL and renders the output. Virtually every Drupal site uses Views for news listings, team pages, product archives, and search results pages.
Do you offer Drupal maintenance retainers?
Yes. After launch, you can take full control of your Drupal instance or continue with a monthly maintenance retainer. Retainers cover monthly security patches, module updates, performance monitoring, content support, and ongoing development. We use Drush and Composer automation, health monitoring, and incident response. Retainers are available from £500/month as a block of hours or a fixed monthly scope.
Who uses Drupal at enterprise scale?
Drupal is used by NASA, the BBC, the White House, NHS Digital, UNICEF, Harvard University, the Australian Government, and thousands of enterprise organisations worldwide. Its dedicated SA-CORE security team, enterprise-grade content modelling, native multilingual, and JSON:API for headless architecture make it the trusted choice for regulated organisations where content complexity, security, and accessibility cannot be compromised.
