WordPress Development

WordPress the way it was meant to be built.

We're not a theme-installation shop. Our WordPress builds are custom-coded themes with clean, maintainable PHP, modern asset pipelines, and performance-first architecture. The kind of WordPress site that scores 95+ on Lighthouse and loads in under 2 seconds — not the kind that needs 47 plugins to function.

  • Custom theme development with Webpack build pipelines
  • Advanced Custom Fields for flexible content management
  • WooCommerce customisation for e-commerce requirements
  • Headless WordPress with React/Next.js frontends
  • Migration from other platforms with full SEO continuity

03
Sprint Build

2-week development sprints with weekly demos.

04
QA Testing

Automated tests, cross-browser, performance audit.

05
Launch

Staging review, deployment, DNS cutover, monitoring.

06
Support

Post-launch monitoring, iteration, ongoing maintenance.

Engineering Standards

Code your next developer can inherit.

The real cost of a website is rarely the build. It is the three years afterwards, when someone else has to change it. Most of what makes that cheap or expensive is decided in the first fortnight, before anything visible exists.

So we spend that fortnight on architecture. What the content types are, how they relate, where the boundaries sit between content and configuration, what belongs in code and what belongs in the database. Get it right and adding a new section in year two takes an afternoon. Get it wrong and it takes a rebuild — which is why so many sites get rebuilt every three years, at full cost, having never actually failed.

  • Version control on every project, with meaningful commit history
  • WordPress coding standards enforced with PHPCS
  • Modern SCSS, ES6 and Webpack pipelines — no page builders, no jQuery plugins bolted on
  • Staging environments from day one, so you see progress rather than a reveal
  • Documented handover: repository access, a walkthrough recording, and notes on the decisions that are not obvious from the code

Our foundation is open source. Thorn is the same starter theme we build client sites on — you can read it before you hire us, which is more than most agencies offer.

Development pricing.

Complexity lives in integrations and business logic. Page count is close to irrelevant.

Marketing site — from £8,000

Custom theme, structured content model, performance and accessibility work included rather than quoted as an extra.

Integrated builds — £15,000+

CRM, ERP, payment, booking or bespoke API work. Anything where your site has to stay in step with a system you already run.

Applications — up to £60,000

Portals, dashboards, multi-role systems and platforms where the site is genuinely software. Our largest web engagements sit here.

Team augmentation — £900/day

A senior developer inside your team for a sprint or a quarter, working to your process and your standards.

Staging from week one.

You should never wait months to see something real. Every project has a URL you can open from the first week.

01
Technical discovery

Integrations, data sources, hosting constraints and whatever legacy system has to keep working.

02
Architecture

Content model, data relationships and the boundary between code and configuration. Decided before anything is built.

03
Environment setup

Repository, staging, CI and a deployment path. Before feature work, not after it.

04
Build

Sprint-based, on staging, in version control, with meaningful commit history rather than one enormous commit.

05
Testing

Cross-browser, device, accessibility and performance. Plus the failure paths — what happens when the API is down.

06
Launch & handover

Deployment, monitoring, documentation and a walkthrough recording. Repository access is yours.

Working With Us

What we expect, and what you should expect.

Development projects fail on communication far more often than on technology. So it is worth being explicit about how this works on both sides.

You are probably a good fit if:

  • You get a staging URL in week one. Not a mockup — the actual site, filling up as it is built.
  • You get told about problems early. If something is going to take longer or cost more, you hear it when we know, not at the deadline.
  • You get the code. Repository access, documentation and a walkthrough at handover. No lock-in.
  • You get an opinion. If we think a requirement is a mistake we will say so with reasoning, and then build what you decide.

We are probably the wrong choice if:

  • We need a decision-maker. One person who can settle a question inside a couple of days. Projects stall on approval far more than on code.
  • We need content roughly on time. The most common cause of a late launch is content, not development.
  • We need access. Hosting, DNS, analytics and whatever systems we are integrating with — ideally at kickoff rather than the week of launch.
  • We need scope discipline. Changes are fine and expected; changes that are not acknowledged as changes are how fixed-price projects sour.

None of this is unusual. It is just rarely written down, and almost every difficult project we have seen went wrong on one of these points rather than on anything technical.

Common questions about working with us.

Custom web development starts from £8,000 for a CMS-driven business website and scales based on complexity. Web applications with user authentication, payment processing, and custom business logic typically range from £15,000–£60,000. We always provide a detailed, line-item quote after our discovery session so there are no surprises.
Yes — we regularly take over existing projects. Whether you need to fix a previous agency's work, add new features to an existing platform, or perform a complete rebuild while preserving your data, we start with a code audit to assess the current state and recommend the most efficient path forward.
WordPress is our primary CMS for most business websites due to its flexibility and ecosystem. For e-commerce we use WooCommerce or Shopify depending on scale and requirements. For headless CMS setups we work with Strapi, Sanity, and Contentful. We recommend the right platform based on your specific needs during discovery.
Absolutely. We build integrations with CRMs (HubSpot, Salesforce), payment platforms (Stripe, PayPal), accounting software (Xero, QuickBooks), marketing tools (Mailchimp, ActiveCampaign), and virtually any system with an API. If it has an API, we can connect it.
We use agile methodology with 2-week development sprints. You get a dedicated project manager, access to our project board, weekly progress calls, and staging environment access so you can review work in real time. No disappearing acts — you always know exactly where your project stands.
Yes. We offer managed hosting on AWS, DigitalOcean, and WP Engine depending on your requirements. Our maintenance plans include uptime monitoring, security patches, performance optimisation, daily backups, and priority support. Most clients choose ongoing maintenance to keep their site secure and performing at its best.
Regularly. We start with a paid audit rather than a quote, because inheriting an unfamiliar codebase without reading it first is how agencies end up committing to numbers they cannot honour. The audit tells you what is actually there, what it costs to stabilise, and whether a rebuild is genuinely cheaper than a rescue — which it sometimes is, and we will say so even though the rescue is the easier sale.
For WordPress: PHP, Advanced Custom Fields, SCSS, ES6 and Webpack, on our open-source Thorn starter theme. For application work: React or Next.js on the front end, Node or PHP on the back, PostgreSQL or MySQL, deployed to Vercel, AWS or wherever your infrastructure already lives. We are deliberately conservative about adopting new tooling — a framework you chose because it was exciting is a maintenance liability three years later.
Yes, and it is one of the highest-return engagements available. Most slow WordPress sites are slow for the same handful of reasons: too many plugins doing overlapping work, unoptimised images, render-blocking assets and no caching strategy. An audit and a focused fix typically moves Lighthouse from the forties into the nineties without touching the design.
Boringly, which is correct. Minimal plugin surface, dependencies kept current, principle of least privilege on database and file permissions, HTTPS everywhere, hardened admin access, and automated off-site backups that someone has actually tested restoring. Most WordPress compromises exploit an outdated plugin nobody was using, which is an argument for installing fewer of them.
Usually, and we will tell you if it is the thing holding your site back. We have no hosting affiliate arrangements, so our recommendation costs us nothing either way. If your host is genuinely the constraint we will say so; if it is fine, we will not sell you a migration you do not need.
Both. Documentation covers the technical decisions that are not obvious from reading the code, plus how to run and deploy the project. Training is a recorded walkthrough for your content team, which works better than a live session because new starters can watch it a year later. If your team wants a live handover as well, that is included.
Yes, provided the scope can flex or the date can. Fixing scope, budget and date simultaneously is where projects break, and the thing that quietly gives is quality. If you have an immovable launch — an event, a campaign, a contractual date — tell us at the enquiry stage and we will scope backwards from it, agreeing in advance what ships first and what follows in a second phase.

Let's build your next growth engine.
