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.

WordPress Development FAQs

What clients ask before commissioning a WordPress build, grouped by topic.

Can you improve website performance and GDPR compliance on an existing site?
Yes, and they are two of the most common reasons people come to us. Website performance work starts with profiling rather than guessing, because WordPress slowness is almost always plugin bloat, an unoptimised database, missing object caching or oversized images rather than WordPress itself. We fix the causes and report against Core Web Vitals field data. GDPR compliance covers consent management that actually blocks scripts before consent rather than after, a lawful basis for the data your forms collect, data retention that is configured rather than aspirational, and a privacy policy matching what the site really does. GDPR compliance is not a plugin, and a cookie banner on its own is not compliance.
Can you speed up our existing WordPress site?
Yes, almost always, and the gains are usually large. Typical causes are plugin bloat, an unoptimised database, missing object caching, oversized images and a theme doing too much work per request. We profile the site to find the real bottleneck rather than guessing, then fix causes instead of layering another caching plugin on top. Most audits produce a 50% to 70% reduction in load time and green Core Web Vitals on mobile.
Can you fix a WordPress site another developer built?
Yes, and it is a significant part of what we do. Whether the original developer has disappeared, an update has broken something, the site has been hacked, or the code is simply undocumented, we start with a paid audit that tells you exactly what you own and what the risks are. You get that assessment in writing and you are free to take it elsewhere.
What ongoing maintenance do you provide?
Support plans cover core, theme and plugin updates tested on staging before going live, daily off-site backups with periodically tested restores, uptime monitoring with alerts, malware scanning, performance checks, and an allocation of development time each month for small changes. Plans start at £150 per month, and you can move between levels as your needs change.
What security measures do you implement?
Correct file permissions, login protection with rate limiting and two-factor authentication, a web application firewall, regular malware scanning, disabled in-dashboard file editing, changed database prefixes, secure headers, and a managed update process. For higher-risk sites we add Cloudflare WAF rules and stricter access controls. WordPress is heavily targeted because of its market share, so hardening is not optional.
Is WordPress accessible and GDPR compliant out of the box?
No, neither. WordPress gives you the tools but compliance is a build decision. We develop to WCAG 2.2 AA with semantic HTML, keyboard navigation, visible focus states, adequate contrast and properly labelled forms, and we test with screen readers. For UK GDPR we implement consent that genuinely blocks cookies until accepted, minimise data collection, set form data retention policies, and make sure the privacy policy matches what the site actually does.
How much does WordPress development cost in the UK?
A custom theme build on an existing design typically runs £4,000 to £12,000. A full design and build is usually £8,000 to £30,000 depending on template count and functionality. Custom plugin development starts around £2,500. WooCommerce builds start around £8,000. Support and maintenance retainers start at £150 per month. We quote fixed price against a written scope so there is no open-ended hourly billing.
Do you do custom WordPress plugin development, Gutenberg blocks and multisite?
Yes, all three. Custom WordPress plugin development covers functionality no off-the-shelf plugin handles properly: booking systems, quote calculators, membership logic, internal tools and integrations, built to WordPress coding standards so they survive core updates. Gutenberg block development gives your editors reusable, on-brand components with guard rails, which produces far cleaner markup than a page builder and is usually the better long-term choice. WordPress multisite suits organisations running many sites from one installation, regional offices, brands or franchises, with shared components and central governance. We will also tell you when you do not need one of these: a WordPress multisite for two sites is usually more trouble than two installations.
Can you build custom WordPress plugins?
Yes. We build plugins for functionality no off-the-shelf option covers, including booking systems, quote calculators, membership and gated content, custom reporting dashboards, and internal business tools. Everything is written to WordPress coding standards with proper hooks and filters, so it survives core updates instead of breaking at the next release, and it stays maintainable by any competent WordPress developer.
Can you integrate WordPress with our CRM or API?
Yes, this is routine work for us. We have integrated WordPress with Salesforce, HubSpot, Microsoft Dynamics, Pipedrive, Mailchimp, Stripe, GoCardless and a long list of industry-specific systems including property feeds, job boards and supplier catalogues. We build against the WordPress REST API and whatever the third party exposes, whether REST, GraphQL, SOAP or a scheduled file transfer.
Can you migrate our site without losing content or rankings?
Yes. Migrations are planned around content integrity and search visibility from the start. We move content, media, users and metadata, map every old URL to its new equivalent with 301 redirects, and benchmark rankings and organic traffic before the move so any change is measured rather than assumed. Migrations run on staging first, then cut over at a low-traffic window with Google Search Console monitored closely afterwards.
Do you build WooCommerce stores?
Yes. We build and extend WooCommerce including custom product types, complex variations, bespoke pricing rules, subscriptions, B2B pricing tiers and checkout customisation, along with the caching and database work that keeps a large catalogue responsive. If you are choosing between WooCommerce and Shopify we will give you a straight answer based on your catalogue, your team and your margins rather than steering you towards whichever we would prefer to build.
