Bespoke WordPress themes, hand-coded.

Custom WordPress theme development from our Bury St Edmunds studio. Themes built from scratch — no page builders, no theme-shop bloat, no plugin Frankenstein. For businesses, agencies and designers across Suffolk, Ipswich and the UK.

There’s a meaningful difference between ‘a WordPress site’ and ‘a site with a custom WordPress theme’. Most agencies sell the first — a marketplace theme configured for your brand, with a page builder bolted on top and a handful of plugins covering the gaps. The result works, but it’s slower, less secure, harder to maintain, and looks broadly like several thousand other sites. We build the second: bespoke themes coded from scratch, native to the WordPress block editor, with nothing in the codebase that doesn’t need to be there.

What you get with a custom theme

Hand-coded from scratch

PHP, HTML, CSS and JavaScript — written specifically for your site. No marketplace theme, no page builder.

Native Gutenberg blocks

Custom blocks built for the WordPress block editor — your team gets editorial flexibility without breaking the design system.

Fast Core Web Vitals

No theme bloat, no unused CSS, no unused JS. Sites typically score 90+ on PageSpeed Insights from day one.

Minimal plugins

Custom themes mean fewer plugins needed for layout, design and functionality. Less attack surface, fewer update headaches.

Yours to keep

You own the theme code outright. Take it elsewhere, edit it freely, hand it to another developer if you ever want to.

WCAG-ready

Built to WCAG 2.2 AA accessibility standards by default. Important for compliance, helpful for SEO.

Mobile-first responsive

Designed for phones first, scaled up to desktop. The way every site should be built in 2026.

Editor-friendly

Your team can update content, add pages and manage media without touching code or breaking the design.

Documented & trained

Every theme ships with written documentation and a training session for your team. No mystery code, no “only we know how this works”.

Why hand-coded beats page builders

The WordPress market is split. On one side: page builder themes (Elementor, Divi, WPBakery, Avada). Easy to start with, instantly familiar, sold on the promise of “drag-and-drop, no developer needed”. On the other side: hand-coded custom themes. Slower to start, but better in every measure that matters over the life of the site.

The page-builder trade-offs that don’t show up until later:

  • Performance. Page builders load substantial CSS and JavaScript on every page regardless of what’s used. Custom themes load only what each page needs. The difference shows up in Core Web Vitals, mobile performance, and SEO rankings.
  • Lock-in. Page-builder content is stored in shortcodes or proprietary block formats. Switch away from the page builder and your content turns to soup. Custom themes use native WordPress blocks and standard markup — portable, future-proof.
  • Security & updates. Page builders ship frequent updates that occasionally break sites. They expand attack surface. Custom themes have fewer moving parts and fewer surprise breaks.
  • Cost over time. Page-builder licences, plugin licences, and the cost of fixing things when they break add up. Custom themes have a higher upfront cost but lower running cost — especially over a 3–5 year life.
  • Design fidelity. Page builders constrain you to their visual vocabulary. Custom themes let your designer’s actual design come through pixel-perfect.

Page builders genuinely have their place — rapid prototyping, smaller sites where the trade-offs don’t matter, situations where the client team wants to make sweeping layout changes themselves. For everything else, hand-coded is the better answer.

Who we build custom themes for

Three audiences, all welcome:

  • Businesses commissioning their own site. Most common. You want WordPress as the CMS (so your team can edit content), but you want a bespoke theme rather than an off-the-shelf one. We work directly with you on the brief, design and build.
  • Designers and design studios needing a developer. You’ve designed the site in Figma or similar, you want it built well in WordPress, and you don’t have an in-house developer (or you do but they’re booked). White-label welcome — the final site is your client deliverable; we just build behind the scenes.
  • Agencies needing a development partner. Same as the above but at agency scale — we’re a known-quantity development resource you can hand projects to when capacity gets tight. Recurring relationships welcome.

How a custom WordPress theme project runs

  1. Discovery (free, no commitment). 30–45 minute call to understand scope, audience, content structure and editorial workflow needs. We agree what the theme needs to do, not just what it needs to look like.
  2. Fixed-price written quote. Sent within 2–3 working days. Clear scope, deliverables, timeline and price. No hourly surprises.
  3. Design phase (or design handover, if you’re bringing your own designs). Wireframes first, then visual design, with structured feedback rounds.
  4. Theme development in our Bury St Edmunds studio. Regular check-ins, a staging environment you can review at any time. Custom Gutenberg blocks built where editorial flexibility matters.
  5. Content migration & launch. If you’re moving from an existing site, we handle the content migration. DNS, hosting and launch handled by us.
  6. Training & documentation. Live walkthrough with your team plus written documentation covering every custom block, template and option in the theme.
  7. Aftercare. Optional monthly hosting and support retainer. No lock-in — cancel monthly, you own the theme code regardless.

What custom WordPress themes cost

  • Smaller theme (3–6 page templates, basic custom blocks): £3,500–£6,000. Suited to small businesses, single-product sites, or simple editorial sites.
  • Standard custom theme (10–15 templates, custom block library, multiple post types): £6,000–£10,000. The most common range for SME sites with proper editorial flexibility.
  • Complex bespoke theme (extensive custom blocks, multilingual, integrations, advanced editorial UI): £10,000–£20,000+. Larger sites, content-heavy publications, multi-author editorial workflows.

Every project is fixed-price after a discovery call. See our website pricing page for the broader picture.

Areas we serve

Our studio is in Bury St Edmunds, but we deliver custom WordPress theme work for clients across Suffolk, Ipswich, the wider East Anglia region, and UK-wide. For Suffolk clients (Bury St Edmunds, Ipswich, Sudbury, Newmarket, Stowmarket, Hadleigh, Felixstowe, Lavenham and the surrounding villages) we’ll come to you for discovery and design sessions if you’d prefer in-person meetings. For clients further afield, the work runs equally well over video. The service itself is the same wherever you are.

Frequently asked questions

A custom WordPress theme is one we build from scratch in code, specifically for your site, rather than configuring a pre-built theme bought from a marketplace. The result is faster, more secure, easier to maintain, and unique to your brand. No page builder bloat, no plugin Frankenstein, no theme settings panel with 400 unused options.
Custom WordPress theme development typically ranges from £3,500 for a small bespoke theme with a handful of templates, up to £15,000+ for complex builds with custom blocks, advanced editorial workflows, multilingual support or integrations. Most SME projects sit in the £5,000–£10,000 range. Always fixed-price after a discovery call.
A typical custom WordPress theme takes 6–10 weeks from kickoff to launch. Simpler themes (3–5 templates, no custom blocks) can complete in 4–6 weeks. Larger themes with custom Gutenberg blocks, complex editorial UIs or integrations usually run 10–14 weeks. We commit to fixed delivery dates at quote stage.
Both. We work directly with businesses commissioning their own site, and we work as the development partner for designers and agencies who need a developer to build out their designs in WordPress. White-label work is welcome — the deliverable is the same standard either way.
No. We hand-code themes in PHP, HTML, CSS and JavaScript, using the native WordPress block editor (Gutenberg) where editorial flexibility is needed. Page builders bloat the codebase, hurt performance, lock you into their syntax, and break in inconvenient ways when they update. Hand-coded themes are faster, more secure, and last longer.
