WordPress Headless Development in London

Building headless WordPress for London organisations, where separating the front end from the content management system means giving up several things editors currently rely on. Preview, page builders and any plugin that renders output on the page stop working — because none of them know about the front end that is now doing the rendering.

Why this comes up

The problem

The decoupled front end is fast, and editors can no longer preview a post before publishing it.

What you get

What we deliver

  • Preview solved deliberately, since editors will not accept publishing blind
  • Plugins that render output identified, as these do not carry across
  • Editing experience rebuilt around structured fields rather than page building
  • Content API designed for what the front end needs rather than exposing everything
  • Caching and revalidation planned, so publishing updates the site promptly
  • The case for going headless stated, because it is a real increase in complexity

WordPress Headless Development in London — common questions

What do editors lose?
Preview and page building, principally. Both depend on WordPress rendering the page, and once something else does that, previewing requires the front end to render draft content — which is solvable and needs building rather than being available by default.
Which plugins stop working?
Anything that outputs markup — forms, sliders, related content, most SEO output. Plugins managing data continue to work fine, and the distinction is whether the plugin's value is in the data it holds or in what it renders on the page.
Is it worth the complexity?
Where you need a front end WordPress cannot produce — an application-like interface, a shared front end across several sources, or performance beyond what caching achieves. For a content site that renders well already, it adds moving parts without a corresponding gain.
How quickly does published content appear?
As quickly as you design for. A statically generated front end needs telling to rebuild the affected pages when content changes, and editors accustomed to changes appearing immediately will notice a delay — so the revalidation approach is part of the requirement.
Do you work with businesses across Greater London?
Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of London businesses do you usually work with?
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
Do you cover the areas around London?
Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
