For over a decade, WordPress was the default choice for business websites in the UK. However, modern UK businesses and digital agencies are increasingly replacing WordPress with Next.js web applications. Here is an honest technical and commercial comparison.
Speed & Performance (Core Web Vitals)
- **WordPress**: Often burdened by heavy plugins, bloated database queries, and unoptimized PHP scripts. Mobile PageSpeed scores frequently hover between 30 and 60.
- **Next.js**: Compiles to optimized HTML, CSS, and minimal JavaScript edge bundles. Consistently achieves **95 to 100 Lighthouse scores**, resulting in sub-second load times across the UK.
Security & Vulnerabilities
- **WordPress**: The world's most targeted CMS. Requires constant plugin updates, security firewalls, and database maintenance to prevent malware infections.
- **Next.js**: Serverless or static deployment model. There are no vulnerable SQL plugins or admin login panels exposed to brute-force attacks, providing bulletproof security by default.
SEO & Conversions
Google UK explicitly rewards fast page load times and stable layout shifts (CLS). Next.js provides complete programmatic control over dynamic OpenGraph images, canonical metadata, and structured JSON-LD schemas.
