Every business owner asks this question sooner or later. And every agency answers it the same way: "it depends." Which is true, but also spectacularly unhelpful when you're trying to put together a budget.
So here's our attempt at a more useful answer. We'll break down what different types of websites actually cost in the UK in 2026, what drives those costs up or down, and where the money really goes. We build websites for businesses across Hertfordshire, Essex, Bedfordshire, Cambridgeshire and London, so these numbers reflect what we see in the real world rather than what a pricing calculator spits out.
The quick answer
If you want a number before you read the rest: a professionally built business website in the UK typically costs between £3,000 and £40,000. That's a wide range because "a website" covers everything from a five-page brochure site to a full ecommerce platform with custom integrations.
Here's a more useful breakdown by type.
Brochure websites: £2,500 to £7,500
A brochure site is the digital equivalent of a business card. It tells people who you are, what you do, and how to get in touch. Think five to fifteen pages covering your services, an about page, a contact form, and maybe a blog.
At the lower end, you're looking at a clean, professionally designed site built on a modern platform with responsive design, basic SEO setup, and content management so you can update it yourself. At the higher end, you'll get custom design work, more considered user journeys, professional copywriting, and a more polished overall experience.
Most small businesses in Hertfordshire and Essex that come to us for a brochure site land somewhere in the £3,500 to £5,500 range. That gets them something they're genuinely proud of without overengineering it.
Ecommerce websites: £5,000 to £40,000
Ecommerce is where the range gets wide. A simple online shop selling twenty products with standard payment processing is a very different project to a multi-category retailer with inventory management, warehouse integrations, customer accounts, and subscription billing.
A smaller ecommerce site built on Shopify or WooCommerce with a custom theme, product setup, and payment integration will typically cost between £5,000 and £12,000. Once you move into custom-built ecommerce with bespoke functionality, integrations with third-party systems like accounting software or ERP platforms, and complex product configurations, you're looking at £15,000 to £40,000 or more.
The key cost driver here isn't the number of products. It's the complexity of what happens after someone clicks "add to basket." Shipping rules, tax calculations, discount logic, inventory syncing; that's where development time accumulates.
Custom web applications: £15,000 to £80,000+
This is where websites stop being websites and start being software. Client portals, booking systems, internal tools, SaaS products, AI-powered features: if your site needs to do something genuinely bespoke, you're in web application territory.
We've built everything from AI business intelligence tools to client document portals with automated data extraction. These projects require proper software engineering: architecture planning, API development, authentication systems, testing, and ongoing maintenance.
The cost depends entirely on scope. A relatively contained web app with a few core features might come in at £15,000 to £25,000. A full platform with multiple user roles, complex data flows, and third-party integrations can easily reach £50,000 to £80,000 or beyond.
If this sounds expensive, consider that you're building a product, not a website. The return on investment for a well-built web application typically dwarfs that of a brochure site.
WordPress vs custom-built: does it matter?
It matters more than most agencies will tell you.
WordPress powers a huge percentage of the web, and for good reason. It's mature, well-supported, and there's a plugin for almost everything. For a standard brochure site or basic blog, WordPress is a sensible choice and will typically cost less than a custom build.
But WordPress comes with trade-offs. Performance can suffer as plugins accumulate. Security requires ongoing vigilance because WordPress is the most targeted CMS on the planet. And when you need to build something that goes beyond what plugins offer, you end up fighting the platform rather than working with it.
We moved to a modern stack (Next.js with Payload CMS) specifically because it gives us the performance, security, and flexibility to build the kinds of features our clients increasingly want. Sites load faster, rank better, and we can extend them in ways that WordPress makes painful.
For most businesses, the platform choice should be driven by what you need the site to do today and what you might need it to do in two years. If the answer is "display information and capture leads," WordPress is fine. If you're thinking about AI features, custom integrations, or anything that feels more like an application than a brochure, a modern custom stack will serve you better.
What actually drives the cost up
Understanding where the money goes helps you make better decisions about where to invest. Here are the biggest cost factors:
Design complexity. A site using a pre-built theme with customised colours and fonts costs far less than a fully bespoke design created from scratch. Custom illustration, animation, and interactive elements all add to the design budget.
Number of unique page templates. Ten pages using two templates is much cheaper than ten pages that each have a completely different layout. Smart agencies design systems, not individual pages.
Content creation. Many quotes assume you'll provide the content. If you need professional copywriting, that adds £50 to £200 per page depending on complexity. Photography adds £500 to £3,000 depending on scope. Don't underestimate this: poor content on a beautifully designed site is like putting cheap tyres on a sports car.
Integrations. Connecting your website to a CRM, email marketing platform, accounting software, booking system, or payment processor takes development time. Each integration has its own quirks and APIs.
SEO setup. Basic on-page SEO should be included in any professional build. But comprehensive SEO (keyword research, content strategy, technical optimisation, local SEO, schema markup) is an ongoing investment that goes well beyond the initial build.
AI and advanced features. This is the newer cost factor. Building AI-powered features like intelligent search, automated recommendations, or interactive tools adds genuine value but requires proper engineering. Budget separately for these.
The costs people forget about
The website itself is only part of the total cost of ownership. Here's what catches people out:
Hosting. Expect to pay £10 to £100 per month depending on traffic, performance requirements, and whether you need a managed service. Cheap hosting is a false economy: it affects speed, uptime, and ultimately your Google rankings.
Maintenance and updates. Websites aren't "done" once they launch. CMS updates, security patches, plugin updates, content changes, and performance monitoring all need attention. Budget £100 to £500 per month for ongoing maintenance, or more if you have a complex site.
SSL certificates and domain renewal. Small but recurring costs. An SSL certificate is non-negotiable in 2026: browsers flag sites without one as insecure. Domain renewal runs about £10 to £50 per year depending on the TLD.
Content updates. Unless your business never changes, you'll need to update your site regularly. Some agencies include a number of content updates in a monthly retainer. Others charge per change. Clarify this before you sign anything.
How to get a realistic quote
Here's our advice for getting quotes that you can actually compare:
First, know what you need before you ask. Even a rough brief makes a massive difference. List the pages you want, the features you need, and any systems the site needs to integrate with. The vaguer your brief, the wider the price range you'll receive.
Second, ask agencies to break down their quote. A single number tells you nothing. You want to see design, development, content, SEO, and hosting as separate line items so you can understand where the money is going.
Third, ask about ongoing costs. The cheapest build quote might come with the most expensive monthly retainer. Look at the total cost over two to three years, not just the upfront number.
Fourth, check what happens after launch. Will the agency help you with updates? Is there a support plan? What's the hourly rate for changes? A website is a long-term asset and you want a partner, not just a builder.
Where Supra Digital sits
We're transparent about this: we're not the cheapest option and we're not trying to be. We build modern, high-performance websites on Next.js and Payload CMS for businesses that want something genuinely effective rather than just "a website."
Our typical projects range from £3,500 for a focused brochure site to £40,000+ for complex web applications with AI-powered features. We work primarily with businesses across Hertfordshire, Essex, Bedfordshire, Cambridgeshire, and London, though increasingly with clients across the wider UK.
What you get for that is a site that loads fast, ranks well, looks professional, and can grow with your business. We also build in AI features that your competitors almost certainly don't have: the kind that actually generate leads rather than just looking impressive.
If you'd like to have a conversation about what your specific project might cost, get in touch. We'll give you an honest assessment, even if the honest answer is that you don't need to spend as much as you think.
