WordPress vs Custom Website — Which Is Right for Your Business?

I've built hundreds of websites. Some on WordPress. Some custom-coded from scratch. And the honest answer to "which is better?" is: it depends.

I know that's not the definitive answer you wanted. But anyone who tells you one is universally better than the other is either selling you something or doesn't build enough websites to know the difference.

Let me break down the real differences so you can make an informed decision.

WordPress: The Good

WordPress powers roughly 43% of the internet. There's a reason for that. It's flexible, it's well-supported, and there's a plugin for practically everything.

Pros:

• Massive ecosystem: Thousands of themes and plugins. Need an events calendar? There's a plugin. Need e-commerce? WooCommerce. Need a booking system? There are dozens of options.
• Content management: If you want to update your own content — blog posts, product pages, team members — WordPress makes it relatively easy. The editor is familiar and most people can figure it out.
• Cost for complex sites: If you need lots of functionality (e-commerce, memberships, LMS), WordPress with plugins is usually cheaper than building it all custom. A custom e-commerce site could cost £10,000+. WooCommerce gets you 80% of the way there for a fraction of that.
• Developer availability: If we get hit by a bus tomorrow, you can find another WordPress developer easily. The platform is so common that any decent developer can pick up a WordPress site.

WordPress: The Bad

Cons:

• Speed: WordPress sites are almost always slower than custom builds. All those plugins, the database queries, the bloated themes — it adds up. We can optimise WordPress to be fast, but it takes effort and ongoing attention.
• Security: WordPress is the most hacked CMS in the world. Not because it's inherently insecure, but because it's so popular that hackers target it specifically. You need regular updates, security plugins, and monitoring. Ignore this and you will get hacked. It's not a matter of if, it's when.
• Plugin dependency: Plugins break. They conflict with each other. They get abandoned by developers. I've seen sites crash because a plugin update was incompatible with another plugin. It's maintenance overhead you don't get with custom code.
• Maintenance cost: Between hosting, premium plugins, theme licences, and security tools, a WordPress site can easily cost £500-£1,500/year in running costs before you even factor in someone to manage it.

Custom Websites: The Good

Pros:

• Speed: A custom site built with modern frameworks (like Next.js, which we use) loads incredibly fast. No bloated plugins, no unnecessary database calls. Google loves fast sites, and fast sites convert better.
• Security: No plugins means no plugin vulnerabilities. Custom sites have a much smaller attack surface. You're not in the crosshairs of every WordPress exploit script running on the internet.
• Exactly what you need: Nothing more, nothing less. Every line of code serves a purpose. There's no theme code you don't need, no plugin features you're not using.
• Modern design: Custom sites can do things that WordPress templates simply can't — smooth animations, unique layouts, interactive elements that feel premium.

Custom Websites: The Bad

Cons:

• Content updates: Unless there's a CMS built in, you can't easily update content yourself. You'll need a developer to make changes. For us, that's included in the subscription — but with other agencies, you're paying per change.
• Higher upfront cost (traditionally): A custom build from a traditional agency will cost more than a WordPress build. Though with subscription models like ours, this difference disappears.
• Developer lock-in: Custom code means you need someone who understands that specific codebase. It's not as universal as WordPress.

So Which Should You Choose?

Choose WordPress if:

• You need complex functionality (e-commerce with hundreds of products, membership areas, learning management)
• You want to update content yourself regularly
• You need lots of integrations with third-party services

Choose custom if:

• Speed and performance matter to you (they should — Google ranks faster sites higher)
• You want a modern, unique design that stands out
• You're a service business with 2-10 pages and don't need a blog CMS
• Security is a priority
• You want something that just works without constant plugin updates

What We Do at Zanacco

We build both. We'll recommend WordPress when it genuinely makes sense — usually for e-commerce or content-heavy sites. For most small business websites (service pages, portfolios, landing pages), we build custom because the result is faster, more secure, and looks better.

And because we offer subscriptions from £49/month, the traditional cost argument for choosing cheap web design with a template doesn't apply anymore. You get a custom-quality site at a WordPress budget.
