WordPress powers somewhere around 40% of all websites. That’s an incredible number, and it means there’s a decent chance your current site runs on it. Or that someone has told you it should.
But “popular” and “right for you” aren’t the same thing. WordPress is brilliant for some businesses and genuinely wrong for others. The problem is that most web designers only know one approach, so they recommend what they know rather than what you need.
Here’s an honest comparison. No religion, no tribalism. Just practical advice on which approach makes sense for your business.
What WordPress actually is
WordPress started as blogging software in 2003. Over the years it evolved into a full content management system — a platform that lets you build and manage a website through a dashboard without touching code.
There are two versions. WordPress.com is a hosted platform (like Wix or Squarespace) where they handle everything. WordPress.org is the self-hosted version where you download the software and run it on your own hosting. When people in the industry say “WordPress”, they almost always mean the self-hosted version.
The self-hosted version is free. The plugins, themes, hosting, and maintenance that make it actually useful are not.
The case for WordPress
WordPress does a lot of things well, and for certain businesses it’s the obvious choice.
Content is easy to manage. If you need to regularly update your site — adding blog posts, changing prices, uploading new portfolio images — WordPress makes this straightforward. You log in, make your changes, hit publish. No developer needed for day-to-day updates.
Plugins for almost everything. Need a booking system? There’s a plugin. Contact forms? Dozens of options. E-commerce? WooCommerce handles thousands of online shops. The plugin ecosystem means you can add functionality without custom development, which keeps costs down.
Loads of developers know it. Because it’s so popular, finding someone to work on a WordPress site is easy. If your current developer disappears (it happens more than it should), you won’t struggle to find a replacement. With custom-built sites, you’re more dependent on the original developer.
Lower upfront cost. A WordPress site typically costs less to build than a fully custom site. A decent WordPress developer can put together a professional business site for £1,000-3,000, depending on complexity. You’re getting a custom design on a proven platform.
The case against WordPress
Here’s where it gets more nuanced. WordPress has genuine downsides that don’t get talked about enough, usually because the person building your site makes their living from WordPress.
Maintenance is constant. WordPress core, your theme, and every plugin you’ve installed need regular updates. Skip updates and you’ll eventually get security vulnerabilities. But updates can also break things — a plugin update that conflicts with your theme can take your site down. Someone needs to manage this, and that someone costs money.
Security is a real concern. Being the most popular CMS in the world makes WordPress the biggest target. Brute force attacks, plugin vulnerabilities, spam injections — these are daily realities for WordPress sites. You’ll need a security plugin, regular backups, and ideally a web application firewall. It’s manageable, but it’s overhead that simpler sites don’t have.
Speed takes work. A fresh WordPress install is reasonably fast. But once you add a theme, a page builder, fifteen plugins, and a few hundred images, things slow down quickly. Getting a WordPress site to load fast requires effort — caching plugins, image optimisation, potentially a CDN. A custom-built site is often faster out of the box because it has far less bloat.
Plugin dependency is a double-edged sword. That plugin you rely on for your booking system? The developer might abandon it. Or release an update that breaks your site. Or start charging for features that were previously free. You’re trusting third-party developers with critical parts of your business website, and you have no control over their decisions.
Page builders add complexity. Many WordPress sites are built with page builders like Elementor, Divi, or WPBakery. These let developers (and clients) build pages visually, but they add significant code bloat, make your site slower, and create a dependency that’s hard to escape. Migrating away from a page builder is often harder than rebuilding from scratch.
What about custom-built sites?
A custom-built site — sometimes called a bespoke site or, increasingly, a site built with a modern framework — is purpose-built for your specific needs. There’s no WordPress backend, no plugins, no theme. Just your site, built with clean code.
Speed. This is the biggest advantage. Custom sites are typically much faster because they don’t carry the weight of a CMS, plugins, and a theme. A well-built custom site can load in under a second. Speed affects everything: user experience, Google rankings, and conversion rates.
Security. No WordPress means no WordPress vulnerabilities. No plugins means no plugin vulnerabilities. A custom static site has an attack surface that’s essentially zero. There’s nothing to hack because there’s no database, no login page, no admin panel.
Less maintenance. No plugins to update, no CMS to patch, no theme conflicts to resolve. Custom sites need occasional maintenance, but it’s dramatically less than WordPress. Your hosting costs are often lower too, because static sites can run on cheaper infrastructure.
Complete control. Every element is built for your specific needs. No working around theme limitations or plugin quirks. If you need something to work a certain way, it can be built exactly that way.
The honest downsides of custom
Content updates need a developer. Unless a headless CMS is built in (which adds complexity), you can’t just log in and change your homepage text. For businesses that rarely update their site, this doesn’t matter much. For businesses that update weekly, it’s a real consideration.
Higher upfront cost. Custom development takes more time than assembling WordPress components. You’re paying for bespoke work, and it costs more. A custom site might run £3,000-10,000+ depending on what you need. The total cost of ownership over three years might be lower (less maintenance, less hosting), but the initial outlay is higher.
Developer dependency. If your site is built in a framework that only your developer understands, you’re tied to them. Good developers use well-documented, widely-known technologies to mitigate this. But it’s worth asking about.
So which do you need?
Here’s the practical decision framework.
WordPress makes sense if:
- You need to update content frequently (weekly blog posts, regular portfolio additions, changing prices)
- You need e-commerce with lots of products (WooCommerce is mature and capable)
- Your budget is tight and you need a professional site quickly
- You want to be able to make basic changes yourself without calling a developer
Custom makes sense if:
- Speed and performance are priorities (they should be, frankly)
- You have a relatively static site that doesn’t change much day-to-day
- Security matters to your industry or clients
- You want the lowest possible ongoing maintenance
- You’re willing to invest more upfront for lower long-term costs
Either can work if:
- You’re a typical small business that needs a professional online presence, some basic content management, and a way for customers to get in touch
The honest answer for most small businesses is that either approach, done well, will serve you fine. A well-built WordPress site beats a badly-built custom site, and vice versa. The quality of the build matters more than the technology behind it.
What matters is that whoever builds your site understands your needs, builds something fast and secure, and doesn’t lock you into something you can’t maintain or afford.
What about Wix, Squarespace, and the others?
Briefly, because people always ask. DIY builders are fine for getting something online quickly and cheaply. They’re not great for performance, SEO, or standing out from competitors using the same templates. They’re a starting point, not a destination.
If you’re currently on a DIY builder and getting enquiries, great — don’t fix what isn’t broken. If you’re not getting enquiries and wondering why, the builder might be part of the problem.
The question to ask your web designer
Next time a web designer recommends a particular platform, ask them this: “Do you build on other platforms too, or just this one?”
If they only build WordPress sites, they’ll recommend WordPress. If they only build custom sites, they’ll recommend custom. Neither is necessarily wrong — specialists are good. But you should know whether you’re getting a recommendation based on your needs or their skill set.
At Happy Webs, we build both. We use WordPress when it genuinely makes sense and custom-built sites when they’re the better fit. Take a look at our web design services for more detail on how we approach it, or check our pricing page for a clear breakdown of what different approaches cost.
Frequently asked questions
Is WordPress still good in 2025?
Yes, WordPress is still a solid platform when built and maintained properly. The key word is “maintained” — WordPress sites need regular updates to stay secure and functional. If you’re willing to keep on top of maintenance (or pay someone to), WordPress remains a capable option for business websites.
Are custom websites faster than WordPress?
Generally, yes. Custom-built sites have less code overhead because they don’t carry the weight of a CMS, theme, and plugins. A well-optimised WordPress site can be fast, but it takes more effort to get there. A well-built custom site is fast by default because there’s simply less to load.
How much does a custom website cost in the UK?
A professionally built custom website in the UK typically starts around £3,000 for a straightforward business site and can go up to £10,000+ for more complex projects. While the upfront cost is higher than WordPress, the ongoing maintenance costs are usually much lower, so the total cost over three to five years can actually be comparable.
Can I switch from WordPress to a custom site later?
Yes, and businesses do this regularly. Your content, images, and domain name all transfer over. The design and functionality get rebuilt from scratch, which is actually an opportunity to improve things. The transition usually takes a few weeks and shouldn’t cause any downtime if managed properly.
