Custom WordPress themes

Custom WordPress themes give you flexibility for laying out your content, without carrying unnecessary code or complexity. They’re built to grow with your organisation, reduce future rebuilds and keep your site lean.

We design custom WordPress themes that match your brand identity and digital strategy. Clean code keeps your site fast and reduces digital impact, unlike page builder frameworks.

Built from scratch

Off-the-shelf themes make you fit your organisation around someone else’s design decisions. A custom theme works the other way round: we start with your brief, then build the site to match it. No unused features carried over, no workarounds for things the template wasn’t built to do.

Why choose us?

Designed and built from scratch

Every theme is designed and coded to match your brand and priorities, with no bloat carried over from generic templates. Clean, minimal code keeps your site fast and reduces its resource footprint.

Flexible functionality

Your theme is built to support your workflows and integrations, whether that's donation forms, membership systems or third-party APIs. Nothing is bolted on — it's built in, so nothing slows down or breaks as your needs grow.

Future-proof and easy to manage

Themes follow WordPress best practice, so they're straightforward to update and simple for your team to manage. You can add content or features without needing a full redevelopment down the line.

Low carbon performance by default

Optimised assets and lightweight architecture mean your site loads quickly and runs efficiently. That's less strain on servers and a smaller footprint, not an add-on but the standard we build to.

FAQs

How much does a custom WordPress theme cost?

Custom WordPress themes are priced per project, based on scope, functionality and complexity. There’s no fixed price because no two builds carry the same requirements. However, we provide a clear, itemised quote before any work begins, so you know exactly what you’re paying for.

Our custom WordPress builds typically sit between £15,000 and £30,000. More complex builds requiring E-commerce / WooCommerce sit between £25,000 and £100,000.

How long does it take to build a custom WordPress theme?

A custom WordPress theme typically takes 2–4 months from research through to launch, depending on the size of the site. The process runs through discovery, design, development, testing and deployment, with regular check-ins so you’re never left wondering where things stand. We also assign account managers to every project and you’ll be onboarded to our project management hub, so we can easily keep in touch as to what stage of the build we’re on.

Why choose a custom WordPress theme over an off-the-shelf theme?

A custom WordPress theme is coded specifically for your organisation, carrying no unnecessary plugins, bloat or design compromises. That lean code also means faster load times and a cleaner structure for search engines to crawl – advantages a template can’t match, since it’s built to serve thousands of unrelated sites rather than yours.

Can I add a donation form or membership system to my WordPress site?

Yes – donation forms and membership systems can both be added to WordPress, either through a plugin or built directly into a custom theme. Plugins are the faster route for a simple donate button, but for higher-volume fundraising or member-gated content, integrating it at the theme level avoids plugin conflicts and keeps the experience consistent with the rest of your site.

Is WordPress a good platform for charities and nonprofits?

Yes – WordPress is a strong platform for charities and nonprofits, offering the flexibility to handle donations, campaigns and content at any scale. Off-the-shelf nonprofit themes can work for simple needs, but a custom-built theme avoids the generic layouts and donation-plugin conflicts that come with template-based charity sites, while keeping running costs proportionate to a charity budget.

Is WordPress still viable for e-commerce

Yes, absolutely. WordPress and Woo (formerly WooCommerce) are immensely powerful and flexible. WordPress remains the most popular web platform in the world and if you get your site built properly (without using any bloated page builder frameworks), it’ll not only be flexible and fast loading it’ll be extremely future-proof too. Shopify is the fastest growing e-commerce platform at the moment, but Woo is vast, and it wins hands down when it comes to customisation, flexibility and getting precicely what you want.

Maintenance, Support & Optimisation

Once live, your custom theme can be supported with managed hosting and maintenance. We handle updates, backups, security, and performance optimisation — keeping your site reliable, fast, and sustainable over time.
