Background
Cantium Business Solutions is a public sector-focused professional services provider delivering IT, HR, payroll, and finance support to clients across the UK. As the company grew and expanded its service offering, its legacy website struggled to keep pace — limiting content management flexibility, SEO performance, and integration with the wider digital ecosystem.
Cantium needed more than a visual refresh. They required a technically sound, secure, and scalable website built on WordPress — one that would give internal teams control over their content, offer modular flexibility for future development, and serve as a robust foundation for digital campaigns and service delivery.
6B was brought on as the technical development partner, tasked with delivering a high-performance, secure, and future-ready WordPress platform.
The Need
Cantium’s previous web infrastructure posed multiple challenges. It was restrictive from a content management perspective, making it difficult for non-technical users to update or optimise pages. Slow page load times and an outdated plugin architecture created SEO limitations and left the site vulnerable to performance and security risks.
The company needed a custom WordPress solution with complete administrative control, structured content relationships, and tight performance optimisation — all without sacrificing ease of use. In addition, the platform had to support multi-role user permissions, integrate with external marketing tools, and allow for modular content deployment across a growing number of service areas.
Above all, the site had to be stable, fast, secure, and fully aligned with enterprise-grade expectations — especially given Cantium’s role supporting public sector clients.
The Solution
6B delivered a fully bespoke WordPress website built with a headless-ready architecture, structured custom post types, and advanced content modelling — ensuring long-term scalability and content flexibility. Rather than relying on pre-made themes or bloated plugin stacks, the development was led by clean, standards-compliant code tailored to Cantium’s exact needs.
Custom post types and Advanced Custom Fields (ACF) were used to give Cantium full control over complex, repeatable content structures — from case studies and service listings to news and thought leadership articles. The CMS was carefully engineered for non-technical users, allowing granular control over page elements without introducing the risks or inconsistencies common with drag-and-drop builders.
6B implemented rigorous performance optimisation measures, including server-level caching, lazy loading, code minification, and a lightweight theme structure to improve page load times and SEO scores. All third-party scripts were audited and only mission-critical integrations were retained to avoid performance degradation.
Security was also a key priority. The site was hardened with best-practice WordPress security measures, including login protection, limited plugin exposure, regular vulnerability scans, and role-based user access controls. The platform was built to accommodate future enhancements — including potential API integrations, campaign-specific landing pages, and multilingual support.
Throughout the project, 6B maintained a consultative, agile approach — working closely with Cantium’s marketing and IT teams to ensure the final product met internal governance requirements while remaining adaptable to evolving business goals.
The Impact
Since the new WordPress platform launched, Cantium has seen major improvements in speed, stability, and administrative flexibility. Internal teams can now publish content in minutes, not hours — with custom fields and content blocks making it easy to scale digital campaigns without developer involvement.
Performance scores improved significantly across key SEO metrics, and the secure, lean backend architecture has reduced maintenance effort and technical debt. The site now acts as a reliable, flexible platform capable of supporting Cantium’s long-term digital strategy and evolving service offer — without the overheads or limitations of off-the-shelf builds.
By focusing on technical excellence and bespoke development, 6B delivered a WordPress solution that gives Cantium full control, high performance, and the flexibility to grow.
