WordPress Theme Development in Derry
Custom themes for Derry sites, built so the theme controls presentation and nothing else. The rule that decides whether a site can ever be redesigned is simple and widely broken: functionality belongs in plugins, and a theme holding your booking form or custom post types traps you permanently.
Why this comes up
The problem
The site runs a purchased theme layered with overrides, so updating it breaks the design and abandoning it would take the content structure with it.
What you get
What we deliver
- Presentation kept in the theme and functionality moved out into plugins
- Block editor patterns supplied, so editors compose pages from approved parts
- Templates for every content type the site actually publishes
- A child theme where a parent theme is in use, keeping updates survivable
- Editor styles matching the front end, since a mismatch produces broken pages
- Front-end weight controlled, as themes are a common cause of slow sites

WordPress Theme Development in Derry — common questions
- Custom theme or a purchased one?
- Purchased themes suit standard sites on tight budgets and carry a lot of code serving features you will never use. Custom is worth it when the design is genuinely specific, when performance matters, or when editors need constraints a general-purpose theme cannot impose.
- Why must functionality stay out of the theme?
- Because a theme is presentation and should be replaceable. When custom post types, shortcodes or integrations live inside it, changing theme means losing content structure and rebuilding features. Sites in that position stay on a theme they have outgrown for years.
- How does the block editor change this?
- It moves layout decisions to editors, which is good until they can assemble pages that look wrong. Supplying a defined set of blocks and patterns gives flexibility inside boundaries, and that balance is most of the work in a modern theme.
- What if we use a page builder?
- Then the theme matters much less and the builder becomes your real dependency. That is a workable choice made deliberately and an unpleasant surprise made by accident, particularly when the content cannot be extracted in usable form later.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
