Custom theme development
Every theme is written from scratch to match your design, with clean, lightweight code that loads fast and gives your team full control in the WordPress editor.
Bespoke WordPress development from a UK agency with over 20 years on the platform. Custom themes, custom plugins, headless implementations and the technical infrastructure to keep complex WordPress installations performing at scale.
We build WordPress websites without page builders or templates. Every theme, plugin and integration is custom-coded to meet your performance, accessibility and compliance requirements. Your team gets a platform built for your needs, not a modified off-the-shelf product.
Our WordPress development supports organisations across every sector we serve as a B2B marketing agency. From SaaS platforms and professional services firms to maritime operators, logistics businesses, construction companies, healthcare providers and public sector teams.
Our WordPress clients include V.Group, Littlefish, East London NHS Foundation Trust, Transaid and Cornerstone Housing, alongside many other technology, healthcare, maritime, charity and public sector organisations whose WordPress websites we build and look after.
WordPress is the only platform we build on, so our developers work in it every day. Each theme is written from scratch for the project, with ACF flexible content layouts that let your team build new pages without touching code and bespoke plugins where a feature needs one. No templates and no page builders.
We deploy through WP-CLI, test performance against Core Web Vitals before launch and harden every installation against common attacks. WooCommerce builds follow the same standards and we keep looking after the code once the website is live.
Every WordPress website we build is bespoke, written by our in-house developers without page builders or modified templates. The services below cover the themes, plugins, integrations and architecture behind each build.
Every theme is written from scratch to match your design, with clean, lightweight code that loads fast and gives your team full control in the WordPress editor.
When an existing plugin falls short, we extend it or build our own, from booking systems and membership portals to reporting dashboards.
We connect WordPress to your CRM, ERP, payment gateways and marketing tools, so your website works as part of your wider systems.
We plan server configuration, caching, database structure and code architecture, so your website stays fast as traffic grows.
See how our WordPress development projects have helped B2B businesses and public sector organisations launch custom-coded platforms built for reliability and performance.
WordPress powers most of what we build at Priority Pixels. The team handles bespoke theme development, block editor setups, WooCommerce stores, multisite architecture and headless implementations, alongside the design, on-page and project delivery work that surrounds them.
WordPress powers a huge portion of the web for good reason. It scales from simple brochure sites to complex enterprise platforms with the right development approach. We build bespoke WordPress sites across sectors with their own platform demands.
Not every WordPress website is built the same way. The development approach you choose has a direct impact on performance, security, scalability and how much control you have over your own site.
Off-the-shelf themes and page builders offer a quick starting point, but they come with trade-offs that most businesses only discover after launch. Slow load times, plugin conflicts, limited customisation and difficulty scaling are common issues we see when businesses come to us for help.
Bespoke WordPress development takes longer upfront, but it gives you a site built specifically for how your business operates. No unnecessary code, no reliance on third-party page builders and no restrictions on what you can do with your own website.
Every WordPress project follows the same core principles regardless of the client or sector. We write clean, maintainable code, build accessibility in from the start, plan for performance at scale and hand over sites that your team can manage confidently without relying on us for every small change.
Before any code gets written, we map out the technical architecture. That means understanding your content structure, user journeys, integration requirements and growth plans. We define the theme structure, plugin dependencies and hosting environment upfront so there are no surprises mid-build. This planning phase is where most agencies cut corners and where most WordPress problems originate.
Every theme we build is bespoke. No purchased themes modified to fit, no page builders adding unnecessary code. Our themes give content editors full control through the WordPress block editor while keeping the front-end lightweight and accessible. Templates are structured around your actual content needs rather than forcing your content into a rigid framework.
Most organisations need WordPress to talk to other systems. CRM platforms, email marketing tools, payment gateways, booking engines, membership databases. We build these connections using documented APIs and tested workflows so data moves reliably between systems without manual intervention or fragile workarounds.
A WordPress site that loads quickly with 100 visitors needs to load just as quickly with 10,000. We configure server environments, implement caching strategies, optimise database queries and structure code so your site handles traffic growth without degradation. Performance is an architectural decision, not something bolted on after launch.
Accessible WordPress development is not an optional extra. We build to WCAG 2.2 AA as standard, testing with screen readers, keyboard navigation and automated scanning throughout the development process. For public sector clients this is a legal requirement. For commercial clients it expands your audience and improves search performance.
The questions we hear most about WordPress development, from custom builds to accessibility and support after launch.
Pre-built themes ship with code designed to cover hundreds of use cases, most of which your site will never need. That unused code still loads on every page, slowing performance and creating security vulnerabilities. Custom development means every line of code serves a purpose specific to your business, giving you faster load times, fewer plugin dependencies and a site your content team can manage without fighting against the template.
WordPress powers over 40% of websites globally but it has specific technical requirements that generalist developers often overlook. Server configuration, plugin architecture, update management, block editor customisation and WordPress-specific security hardening all require hands-on experience. Our team has worked exclusively with WordPress since 2003 and currently maintains over 200 sites, which means we have encountered and resolved most issues before they reach your project.
Most projects run between 8 and 16 weeks depending on complexity. A brochure site with standard content templates sits at the shorter end. Projects involving custom integrations, membership systems or complex content workflows take longer because the planning and testing phases need more time. We scope every project in detail before quoting so timescales are realistic from the start.
Yes. We regularly connect WordPress with CRM platforms, email marketing tools, payment gateways, booking engines and internal databases. Each integration is built using documented APIs and tested thoroughly before going live. If your system has an API, we can connect it. If it does not, we explore alternatives like webhook triggers or scheduled data syncs.
We build to WCAG 2.2 AA as standard on every project. That means semantic HTML, proper heading structures, keyboard navigation, screen reader compatibility and sufficient colour contrast throughout. For public sector clients where accessibility compliance is a legal requirement, we provide full documentation and testing evidence as part of the handover.
A website launch is a starting point, not a finish line. We offer ongoing WordPress support covering security monitoring, plugin updates, performance optimisation and regular development work for new features or content changes. Most of our development clients move onto a support agreement so they have dedicated technical resource available when they need it.
