Our WordPress Development Services
End-to-end WordPress solutions for businesses that demand quality.
Custom Theme Development
We design and build bespoke WordPress themes built for your brand and business goals. Our themes are built with clean PHP, modern CSS, and vanilla JavaScript, no bloated page builders or unnecessary dependencies. Every theme is fully responsive, accessible, SEO-optimised, and designed to load in under 2 seconds. We use Advanced Custom Fields (ACF) to create intuitive content management interfaces that make updating your site simple.
Plugin Development & Customisation
When off-the-shelf plugins don't meet your needs, we build custom WordPress plugins. From custom post types and advanced search functionality to API integrations and booking systems, we develop solutions that extend WordPress to match your exact requirements. We also customise existing plugins, optimise plugin performance, and resolve conflicts between plugins.
Website Migration & Redesign
We migrate websites from any platform to WordPress: Wix, Squarespace, Joomla, Drupal, or static HTML. Our migration process preserves all content, SEO data, and URL structures with proper 301 redirects to maintain your search rankings. For redesigns, we refresh your visual identity while improving performance, usability, and conversion rates.
Speed & Performance Optimisation
WordPress sites can become slow with poor hosting, unoptimised plugins, and heavy themes. We transform sluggish sites into lightning-fast experiences through server-side caching, image optimisation, database cleaning, CDN configuration, lazy loading, and code minification. Our optimised WordPress sites consistently achieve 90+ PageSpeed scores and sub-2-second load times.
SEO-First Architecture
Every WordPress site we build is architected for search engine visibility. We implement proper heading hierarchies, schema markup, clean permalink structures, XML sitemaps, internal linking frameworks, and Core Web Vitals optimisation. We configure Rank Math or Yoast SEO for maximum effectiveness and create content templates that make SEO-friendly publishing simple. See our <a href='/services/wordpress-seo' class='text-teal hover:underline'>WordPress SEO services</a> for ongoing optimisation.
Security Hardening
WordPress powers 43% of the web, making it a target for hackers. We implement comprehensive security measures including two-factor authentication, login attempt limiting, file permission hardening, security headers, malware scanning, automated backups, SSL configuration, and regular core/plugin updates. Our security-first approach protects your business and your customers' data.
WooCommerce Development
We build WooCommerce stores with custom product pages, advanced filtering, subscription functionality, and payment gateway integrations. Our WooCommerce builds are optimised for speed and conversions, with custom checkout flows and upsell mechanisms that increase average order values.
Ongoing Maintenance & Support
WordPress requires regular maintenance: core updates, plugin updates, security patches, backups, and performance monitoring. We offer monthly maintenance packages that keep your site secure, fast, and up-to-date. Our support includes bug fixes, content updates, and new feature development as your business grows.

A WordPress Development Agency You Can Hand Over To
The most common thing we hear from new clients is that their previous developer disappeared and nobody can work out what they left behind. So the standard we hold ourselves to is straightforward: everything we build should be picked up by any competent WordPress developer without needing us.
That means WordPress coding standards, version control, staging environments, documented custom code and no undocumented dependencies. Our WordPress developers work in PHP, JavaScript and SQL against clean, conventional WordPress architecture rather than a proprietary framework that ties you to one WordPress development company.
As a WordPress development agency and WordPress agency UK businesses use for both build and upkeep, we offer WordPress support and maintenance alongside development: updates tested on staging, daily backups, uptime monitoring, security scanning and monthly website performance checks against Core Web Vitals. Plenty of clients come to us for maintenance first, having been left with a site nobody was looking after, and move on to development work later.
Hire Experienced WordPress Developers in the UK
WordPress powers a very large share of the web, which means the supply of people willing to call themselves WordPress developers is effectively unlimited and the quality range is extreme. If you are looking to hire experienced WordPress developers UK businesses can rely on, and to know what separates experienced WordPress developers from the merely available, the questions worth asking are narrower than most briefing documents suggest.
Ask what happens under the theme. Anyone can install a premium theme and a page builder. The difference shows up two years later, when the site is slow, the page builder has locked your content into proprietary shortcodes, and nobody can change a template without breaking three others. We do custom WordPress development against clean, conventional architecture, which means the next developer can read it and you are not tied to us.
Ask about the specific disciplines. Custom WordPress development, WordPress theme development, WordPress plugin development and WordPress support and maintenance are four different skills, and most freelancers genuinely have two of them. A site needing a bespoke theme, a custom plugin talking to your CRM, a Gutenberg block set your editors can actually use and ongoing maintenance needs all four, and hiring for one and hoping is how projects stall at 80%.
Ask who owns what at the end. The code, the hosting account, the domain, the repository and the documentation should all be yours, and you should be told so in writing before you start. We hand over a documented repository and a maintenance runbook as standard, because the entire point of building to WordPress coding standards is that you are not dependent on the person who built it.
Ask what they will refuse to do. An experienced developer will talk you out of things: a custom plugin where a well-maintained existing one will do, a multisite install for two sites that would be simpler apart, a headless build for a brochure site. We would rather lose the extra scope than maintain something that should never have existed.
Our team. Development work is done by the developers you speak with, in PHP, JavaScript and SQL, working through Git with staging environments. Fixed-scope projects have a written specification and staged payments. Retainers cover continuous development where the roadmap is ongoing. Either way you keep everything.
What We Build with WordPress
WordPress runs a large share of the web, which means the standard of work varies enormously. We build to WordPress coding standards, with version control, staging environments and documentation, so what you own is maintainable by anyone.
Custom WordPress theme development
Bespoke themes built from your design rather than a marketplace template bent into shape. Written in PHP with modern build tooling, using custom post types and fields so your team edits content through clear, purpose-built screens instead of wrestling a page builder.
Gutenberg block development
Custom Gutenberg blocks that give editors reusable, on-brand components with guard rails, so pages stay consistent no matter who builds them. This is the modern alternative to heavyweight page builders, and it produces far cleaner markup and better Core Web Vitals.
Custom WordPress plugin development
Plugins built for functionality no off-the-shelf option covers: booking systems, quote calculators, membership logic, custom reporting, internal tools. Built to WordPress coding standards so they survive core updates rather than breaking at the next release.
WooCommerce development
WooCommerce stores built and extended properly, covering custom product types, complex variations, bespoke pricing rules, subscriptions, B2B pricing tiers, and checkout customisation. Plus the database and caching work that keeps a large catalogue fast.
Headless WordPress
WordPress as a content back end serving a separate front end through the REST API or GraphQL, where you need editorial workflow with a decoupled application. We are candid about when this is genuinely worth the extra complexity and when a well-built conventional theme is the better call.
WordPress multisite
Multisite networks for organisations running many sites from one installation, whether that is regional offices, brands or franchises. Shared components and central governance, with local control where it is actually needed.
API and Third-Party Integrations
Most business websites are not islands. They need to talk to the systems that actually run the company, and the quality of those connections decides whether your site saves time or creates work.
CRM and marketing platforms
Salesforce, HubSpot, Dynamics, Pipedrive and Mailchimp connected so enquiries land in your pipeline with the right source attribution, rather than sitting in a WordPress inbox nobody checks.
ERP, POS and third-party APIs
Custom integrations built against the WordPress REST API and third-party APIs, covering stock, pricing, bookings, property feeds, job boards and supplier catalogues. Where a REST or GraphQL endpoint exists, we can connect it.
Payments and bookings
Stripe, GoCardless, PayPal and Klarna integrated for payments, plus booking and scheduling systems with availability logic that reflects how your business actually works.
Cloudflare and infrastructure
Cloudflare configured for CDN, caching, image optimisation and WAF protection, alongside hosting selection, staging environments and deployment pipelines so changes are tested before they reach your customers.
Fixing a Broken or Inherited WordPress Site
A large share of our WordPress work is not new builds. It is rescuing sites that someone else left behind. If any of these describe your situation, it is a solvable problem and usually a cheaper one than starting again.
Site is slow
Usually plugin bloat, an unoptimised database, missing object caching, oversized images or a theme doing far too much per page load. We profile it, then fix the causes rather than layering another caching plugin on top.
Site has been hacked
We clean the infection, remove backdoors, patch the entry point, restore from a known-good backup where needed, submit for reconsideration if Google has flagged the domain, then harden the installation so it does not recur.
Update broke something
A core, theme or plugin update has taken down part of the site. We diagnose the conflict, roll back safely, then fix the underlying incompatibility so you are not stuck refusing updates forever.
Original developer has gone
Undocumented custom code and no handover. We audit what you own, document it, remove what is unsafe, and get you to a position where any competent developer could pick it up.
Page builder has taken over
Sites drowning in shortcodes and nested builder markup that nobody can edit and Google struggles to render. We migrate content to clean Gutenberg blocks and recover both editability and Core Web Vitals.
Site will not scale
Traffic or catalogue growth has outrun the build. We handle database optimisation, query tuning, caching strategy, and hosting migration to infrastructure that matches the load.
We start with a paid audit rather than a quote pulled from thin air. You get a written assessment of the code you own, the risks in it, and a prioritised plan, and you are free to take that to any developer. Most clients stay, but the audit is genuinely yours.
Performance, Core Web Vitals and Hosting
WordPress has a reputation for being slow, which is unfair to WordPress and fair to a lot of WordPress sites. The platform is not the problem. Twenty plugins, an unoptimised database, a bloated theme and shared hosting are the problem.
We work through the whole stack: page, browser, object and database caching, image compression with modern formats and correct sizing, CSS and JavaScript minification and deferral, database cleanup and query optimisation, a CDN through Cloudflare, and replacing heavy plugins with lighter alternatives or purpose-built code.
The target is green Core Web Vitals on mobile, covering Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift, because those are the metrics Google actually measures and the ones users feel. We also advise on hosting, since the best-optimised site in the world still struggles on inadequate infrastructure.
Security, GDPR and Accessibility
Security hardening. WordPress is the most attacked platform on the web purely because of its market share. We harden installations with correct file permissions, login protection and two-factor authentication, a web application firewall, malware scanning, disabled file editing, database prefix changes, and a managed update process with staging so patches are tested before they go live.
UK GDPR compliance. Cookie consent implemented properly rather than a banner that sets cookies before anyone clicks, data collection minimised, privacy policies matched to what the site actually does, form data retention policies applied, and processor agreements in place for the third parties you use.
WCAG accessibility. We build to WCAG 2.2 AA: semantic HTML, keyboard navigation, visible focus states, sufficient colour contrast, accessible forms with real labels, alt text discipline and screen reader testing. This is a legal expectation for public sector sites and an increasingly commercial one everywhere else. It also happens to improve SEO, because the same semantic structure that helps a screen reader helps a crawler.
Support, Maintenance and Migration
Support and maintenance. Ongoing plans cover core, theme and plugin updates applied on staging first, daily off-site backups with tested restores, uptime monitoring with alerting, security scanning, performance checks, and a set allocation of development time each month for small changes. Priority response times are included.
WordPress migration services. Moving hosts, moving domains, moving from another CMS, or consolidating several sites into a multisite. We handle content, media, users, URL structure and 301 redirects, with rankings benchmarked before the move so nothing is lost quietly. Migrations run on staging first and cut over at a low-traffic window.
If your site also needs to rank rather than simply work, our WordPress SEO services pick up where development finishes, and the two teams work from the same brief.
Areas We Serve
WordPress development is delivered remotely through staging environments, version control and scheduled calls. Clients see work in progress on a staging URL rather than waiting for a reveal at the end, which removes most of the reason to be in the same building.
We build and maintain WordPress sites for organisations in Edinburgh, Bristol, Nottingham, Sheffield, Newcastle, Cardiff, Southampton and Oxford, including several multisite networks spanning regional offices. Support and maintenance clients are spread across the whole of the UK.
