WordPress vs Custom-Built Websites: Total Cost of Ownership Over 5 Years

How Much Does a WordPress Website Cost in the UK?

A self-hosted WordPress website in the UK typically costs between £400 and £7,000 to build, then another £30 to £200-plus a month to run once you fold in hosting, premium plugins and maintenance. Do it yourself on WordPress.com and you can start from nothing. Brief a bespoke agency build for a larger business and you can sail past £15,000.

That's a wide range, and the reason is simple. "WordPress" isn't one thing. It's at least four: a free hosted plan, a self-hosted install you configure yourself, a freelancer build, and a full agency project. Each carries a completely different price tag.

The short version, before we get into the detail:

*Build-cost bands drawn from Startups.co.uk and Authentic Style; ongoing costs from Fasthosts.*

We build custom websites on Next.js at Brambla, not WordPress, so we've no dog in the "which CMS" fight. What follows is the honest arithmetic on both sides: what WordPress actually costs to build and run in the UK, where the costs hide, and when a custom build earns its keep over the life of the site.

Why WordPress Is "Free" But a WordPress Website Is Not

Most of the confusion around WordPress pricing comes down to a single word: free. The software itself — the open-source content management system behind around 41.5% of all websites, per W3Techs — genuinely costs nothing to download and install.

But software isn't a website. Turning WordPress into something live and working means paying for everything around it: a domain, hosting, usually a premium theme, nearly always a handful of paid plugins, and, unless you're doing it all yourself, someone's time to bolt it together.

Free is the price of the engine, not the car. Every real WordPress website in the UK carries recurring costs, and the biggest variable by a distance is who builds it.

WordPress.com vs WordPress.org: Two Very Different Price Models

Before you can compare prices, you have to know which "WordPress" you're pricing, because the two work in opposite directions.

WordPress.com is a hosted service run by Automattic. You pay a monthly plan and they handle hosting, security and updates. It's the simpler, more predictable option, but you're boxed in by whichever plan you're on, and plugins and custom code only unlock on the higher tiers.

WordPress.org (the "self-hosted" one) is the free software you install on hosting you provide. It's far more flexible — any theme, any plugin, any custom code you like — but hosting, security, backups and every update land on your desk, or on the desk of whoever you pay to handle them.

WordPress.com plan pricing (UK)

These are the plans published at wordpress.com/pricing (checked July 2026), shown as the monthly-equivalent price on annual billing:

Here's the catch most people trip over. You generally need the Business plan (£25/mo and up) before you can install the plugins and custom themes that make WordPress worth choosing in the first place. The cheaper tiers are closer to a basic website builder than "proper" WordPress. If you're weighing the hosted builders against each other, our guide to the true cost of a DIY website compares WordPress.com, Wix and Squarespace over three years.

The Real Cost of a Self-Hosted WordPress Website

Most professionally built WordPress sites in the UK take the self-hosted (WordPress.org) route, because it's the only way to get full control. Here's what the individual pieces cost.

Where plugin costs quietly add up

Plugins are where a "cheap" WordPress site gets expensive. A typical small business site leans on several paid ones, and most bill an annual licence that renews every single year:

• SEO — Yoast SEO Premium, for instance, is around £79/year (Startups.co.uk)
• Security — a firewall or malware plugin, usually £99–£199/year
• Backups — a dependable backup plugin, £50–£100/year
• Forms — a proper contact or lead form, £49–£299/year
• Page builder — Elementor Pro or similar, £49–£199/year
• Performance/caching — often free, sometimes £49–£99/year

A modest, sensibly chosen plugin stack lands at roughly £200–£500 a year. Every year. And that's before you add anything specialised like bookings, memberships or e-commerce.

How Much Does a WordPress Website Cost by Who Builds It?

The single biggest number in your total is who does the work. The same brief costs wildly different amounts depending on whether you build it, hire a freelancer, or hand it to an agency.

*Bands from Startups.co.uk (DIY/advanced/bespoke/e-commerce) and Authentic Style (£3,500–£15,000 bespoke/large e-commerce).*

Worked example: a typical 5-page small business WordPress site

Say you want a professional 5-page brochure site (home, about, services, blog, contact) built by a freelancer, on managed hosting, with a sensible plugin stack. A realistic first year looks like this:

• Freelancer build: £1,500 – £3,000
• Managed hosting: £150 – £300/year
• Premium theme: £60 – £100
• Plugins (SEO, security, backups, forms): £200 – £500/year

Add it up and you're at roughly £1,900 – £3,900 in year one. Then £350–£800 a year afterwards in renewals and hosting, before a single maintenance callout or fix. Hold onto that "year one is the cheapest year" idea, because it's the hinge the whole comparison turns on.

Custom WordPress Themes and Plugins: What Bespoke Work Costs

Not every WordPress site runs on an off-the-shelf theme. When a business needs something the plugin library can't offer, it commissions custom work — and this is often the moment WordPress stops being the cheap option.

• A custom WordPress theme (a design built specifically for you, rather than a bought template) typically starts around £1,000 and climbs past £5,000 depending on complexity, sitting inside the freelancer-to-agency bands above.
• A bespoke WordPress plugin — functionality written from scratch — is priced by developer time. At the £20–£150/hour rates quoted by Startups.co.uk, even a modest one can run to several hundred or several thousand pounds, and it then needs maintaining as WordPress and PHP move on beneath it.

And here's the bit worth sitting with. Once you're paying for a custom theme *and* custom plugins, you're funding a bespoke build anyway — just bolted onto a CMS that was never designed around your specific requirements. At that price, a purpose-built site frequently delivers more for the money. That's the exact scenario we dig into in WordPress vs Next.js: when to go headless.

The Costs Nobody Quotes You Upfront

Everything above gets a WordPress site live. The costs below are the ones that turn up later — the reason "total cost of ownership" matters far more than the build quote. Fasthosts themselves peg realistic long-term running costs at anywhere from £50–£100/year for a personal blog to £500–£5,000+ a year for a professional or e-commerce site (Fasthosts). Here's where that money goes.

Plugin renewals

Nearly every premium plugin bills an annual renewal. The £200–£500 you spent on plugins in year one isn't a one-off. It comes round again every year, and some vendors nudge the price up at renewal.

The broken-update problem

WordPress core updates. Plugins update. Themes update. And they don't always get along. A WooCommerce update can break your checkout. A page-builder update can scramble a layout. A PHP version bump can take down a plugin that hasn't kept pace. When that happens on a live site, you need a developer. A quick fix is £75–£150; a serious conflict that means rebuilding sections can be £300–£800 or more. Most active WordPress sites hit a couple of these across five years.

Performance degradation

WordPress sites have a habit of slowing down over time. The database swells, plugins pile up, and the media library fills with unoptimised images. Hosting that felt fine in year one becomes a bottleneck by year three. Performance work — caching, image pipelines, database pruning — typically runs £300–£600 a go, and plenty of sites need it once or twice over five years.

Hosting upgrades

Cheap shared hosting degrades as the server fills up and your traffic grows. Moving to a VPS or a managed plan halfway through the site's life adds cost that was never in the original budget. (If you're weighing hosting tiers, our shared vs managed hosting guide breaks down the real difference for UK small businesses.)

Security: Why WordPress Is the Biggest Target

This one earns its own section, because it's consistently underestimated, and it's a genuine cost rather than a scare story.

Because WordPress powers such a large slice of the web, it's the most attacked platform going. Security firm Sucuri's 2023 Hacked Website Report found that WordPress accounted for 95.5% of the infected CMS websites they cleaned that year, against 1.7% for Joomla and 0.6% for Magento (Sucuri).

Sucuri are careful to add the caveat that actually matters. Those figures, they write, "do not mean that these platforms are more or less secure than other platforms" — they reflect WordPress's sheer market share, nothing more. WordPress isn't badly built. It's simply a big, obvious target, and automated attack scripts spend their days hunting for known holes in popular plugins and out-of-date installs. Keep the site meticulously updated and you're mostly fine. Let it drift, and you're exposed.

The cost of a compromise isn't only the clean-up (£200–£800 in developer time for a serious infection). If Google's malware scanner flags your site, your organic traffic can evaporate within hours, and getting it back — requesting a review, cleaning the infection, waiting to be re-evaluated — can take two to four weeks. For a business that runs on its website for leads, that's the most expensive line of all.

A custom-built site puts a smaller, less predictable attack surface on the table: no `/wp-admin` login to brute-force, no publicly documented plugin versions to scan, no off-the-shelf vulnerabilities to point a script at. It isn't magically unhackable — nothing is — but it takes the automated-attack economics off the table.

Performance: WordPress vs a Lean Custom Build

A well-configured WordPress site on decent hosting can be quick. Plenty are. But the *default* drift of a WordPress site is towards more weight over time: every plugin adds scripts and styles, page builders spit out extra markup, and the theme piles on JavaScript.

Google's Core Web Vitals measure real-world load speed, and they feed into rankings. The target for Largest Contentful Paint is under 2.5 seconds; a lot of WordPress sites on standard hosting sit at 3–5 seconds on mobile. A custom build starts from a clean codebase with no plugin overhead — nothing loading 400 lines of CSS for a layout that appears on one page — so it opens from a higher performance baseline and tends to hold it. Anywhere speed touches revenue (e-commerce, paid traffic, lead generation), that gap has a pound value attached.

WordPress vs a Custom-Built Website: 5-Year Total Cost

Here's where "WordPress is cheaper" finally gets tested properly. The figures below are illustrative Brambla estimates — not third-party data — for a typical UK small business site (a service business, 6–12 pages, standard functionality), modelled across the full five years rather than just the build.

WordPress 5-year cost of ownership (illustrative)

Custom-built 5-year cost of ownership (illustrative)

Three things worth taking from this.

First, WordPress really is cheaper in year one, often by a lot. If the budget's tight and you need to be live quickly, that gap is real and it counts.

Second, the gap narrows sharply across five years. At the lower end, a £2,500 custom build on WebsiteCare Essential comes to £6,475 over five years — squarely comparable with a mid-range WordPress site once you've counted the renewals, the fixes and one security incident.

Third, custom costs are predictable where WordPress costs are lumpy. The custom column is a flat, known monthly figure. The WordPress column swings by nearly £8,000 depending on how many things break, whether you get hacked, and when your hosting finally maxes out.

None of which even touches the time cost — the hours you or your team burn babysitting plugin updates, chasing a developer over broken pages, and living with a slow site. That time is worth real money too.

The Migration Cost Most People Forget

One cost never shows up in the original WordPress decision: the cost of eventually moving *off* WordPress. Plenty of businesses start there, outgrow it, and then face a rebuild that can't simply recycle the old site. The design has to be rebuilt, the content exported and cleaned, the URLs mapped with redirects to protect SEO, and any custom functionality reconstructed from scratch.

We quote these migrations regularly, and a typical small business move from WordPress to a custom build runs £1,500–£4,000 depending on complexity — on top of the original WordPress spend. If you already suspect you'll outgrow a standard CMS, folding that eventual migration into today's decision often changes the maths entirely.

Why Are Businesses Moving Away From WordPress?

Fair question, and one that comes up in search a lot. WordPress isn't dying — it still powers roughly two in five websites — but a steady stream of businesses are migrating away, and for a handful of consistent reasons:

• Maintenance fatigue. The endless cycle of updates, plugin conflicts and security patching wears thin, especially for owners who'd rather be running their business than nursing a CMS.
• Performance ceilings. Plugin-heavy sites struggle with Core Web Vitals, and speed increasingly moves both rankings and conversions.
• Security exposure. Being the biggest target (see the Sucuri figures above) makes ongoing vigilance non-negotiable.
• Plugin dependency risk. A site can be one abandoned plugin or one licencing change away from a headache.

The businesses that leave tend to be the ones whose website has become critical to revenue — the point where reliability and speed start to matter more than the low entry price. For everyone else, WordPress stays a perfectly sensible choice, which brings us to the fair part.

When WordPress Is the Right Choice

We build custom by default, but WordPress genuinely wins in some situations, and we'll happily say so:

• Content-heavy editorial sites. WordPress's writing and editorial workflow — posts, categories, revisions — is excellent. If your main output is regular articles or news, it's hard to beat.
• A specific plugin dependency. If your model hangs on a mature plugin (a particular booking system, membership platform or niche integration), the WordPress library is unmatched. Rebuilding a mature WooCommerce equivalent from scratch would cost far more.
• A genuinely tight budget. If you've got £1,500 and can't stretch, a well-built WordPress site beats no site. Our 7 Day Website from £1,200 is a fast custom alternative in the same bracket, but a good freelancer WordPress build is a legitimate call.
• In-house WordPress skills. If someone on your team already handles updates and plugins with confidence, the hidden maintenance cost drops, because it's absorbed internally.

To be crystal clear: Brambla doesn't build WordPress sites — we build on Next.js. So if WordPress genuinely is the better fit for you, we'll tell you straight and point you in the right direction rather than sell you something we don't offer.

When a Custom Build Makes More Sense

A custom-built site — in our case on Next.js, the framework behind the likes of Nike, TikTok and Notion — tends to win when:

• Performance is business-critical. E-commerce, lead generation, anything with paid traffic behind it, where load speed nudges conversion rates.
• You need unique functionality. Requirements that don't map neatly onto an existing plugin are better built for purpose than wrestled onto a CMS.
• You're thinking in five-year terms. As the tables show, the long-run gap is far smaller than the year-one numbers suggest — and you trade surprise invoices for a predictable monthly cost.
• Security posture matters. Regulated sectors, and any business handling sensitive customer data, benefit from the smaller attack surface.
• You want out of plugin dependency. No reliance on a theme developer's continued goodwill, an abandoned plugin, or a CMS company rewriting its licencing terms.

For online stores specifically, the platform choice is its own puzzle — we work through it in Shopify vs WooCommerce vs custom.

Brambla's Approach

We build custom on Next.js by default because, for most businesses that lean on their website, it produces better long-term outcomes. Our Custom Website service starts at £2,500 and scales with the requirements, and our 7 Day Website delivers a clean, fast, custom-built site in a week from £1,200 for businesses that need to be live quickly.

Every site we build is looked after on a WebsiteCare plan (£65, £125 or £245 a month) covering managed hosting, SSL, security monitoring, automated backups and dependency updates — the plugin stack, hosting and maintenance a WordPress site needs, rolled into one predictable cost with no renewal roulette. You'll find the full breakdown for every service on our pricing page.

The aim is always the right solution for your situation — and that includes telling you when WordPress suits you better than anything we'd build.

Frequently Asked Questions

Is a WordPress website really free? The WordPress software is free to download and install. A WordPress *website* is not — you'll pay for a domain, hosting, usually a premium theme, and almost always paid plugins, plus developer time unless you build it yourself. A free WordPress.com plan exists, but it comes with WordPress branding, no custom domain, and no plugins or custom themes.

How much does a WordPress website cost in the UK for a small business? A professional 5-page small business WordPress site typically costs £1,500–£3,000 to build via a freelancer, plus £350–£800 a year afterwards for hosting, plugin renewals and basic maintenance. DIY brings the build cash cost down to £400–£800 but adds significant time; an agency build runs higher.

Is WordPress outdated in 2026? No. WordPress still powers around 41.5% of all websites and remains actively developed. It's a mature, capable platform. The trend isn't that WordPress is obsolete — it's that some businesses, as their site becomes revenue-critical, come to prefer the speed, security profile and predictable cost of a custom build over WordPress's maintenance and plugin overhead.

Which is cheaper, Wix or WordPress? For a simple site with no developer involved, a Wix or WordPress.com plan can work out cheaper and simpler than self-hosted WordPress, because hosting and maintenance are bundled in. Self-hosted WordPress becomes more cost-effective — and far more flexible — once you need custom functionality. We compare the hosted builders in detail in our true cost of a DIY website guide.

How much does a custom WordPress theme or plugin cost? A custom WordPress theme usually runs from around £1,000 to £5,000+, and a bespoke plugin is priced by developer time (roughly £20–£150/hour), so even a modest one can reach several hundred to several thousand pounds — and then needs ongoing maintenance. Once you're paying for both, you're funding a bespoke build regardless.

How much does it cost to migrate off WordPress? A typical small business migration from WordPress to a custom build costs £1,500–£4,000 depending on complexity — covering the design rebuild, content export and cleaning, URL redirects to protect SEO, and rebuilding any custom functionality.

What does WebsiteCare include? WebsiteCare is our website hosting, security and maintenance service: managed hosting, SSL, malware scanning, firewall management, automated backups and dependency updates. The Growth (£125/mo) and Premium (£245/mo) tiers also include monthly support minutes for content updates.

The Bottom Line

WordPress isn't a bad choice. It's the right choice in specific circumstances. But "WordPress is cheaper" only holds if you squint at the smallest slice of the picture: the year-one setup, before the plugin renewals, before the first broken-update callout, before a security incident, before the eventual migration.

Over five years, a well-maintained custom site on a predictable WebsiteCare plan is often cost-comparable with a professionally managed WordPress installation — with fewer moving parts, a smaller security target, a higher performance baseline and no migration debt waiting for you if the business grows.

If you're weighing up a new site or a rebuild, we're happy to have the honest conversation — including telling you when WordPress is the better fit.
