If you've started asking web design agencies for quotes, you've probably noticed the numbers all over the place — one agency says £300, another says £3,000, for what sounds like the same project. This guide breaks down what actually drives website cost in the UK, so you can tell a fair quote from an inflated one, and a suspiciously cheap one from a genuine bargain.
What actually determines website cost?
Four things move the price more than anything else: how many pages you need, whether the design is custom or template-based, how much content (writing, photos, video) needs producing, and what functionality the site needs beyond static pages — booking systems, product catalogues, membership areas and so on.
A five-page brochure site for a local tradesperson and a fifty-page catalogue site for a wholesaler are both "websites," but they aren't remotely comparable projects, which is why a single "average cost" figure is almost meaningless without context.
Typical UK website costs by project type
| Project type | Typical UK cost |
|---|---|
| Simple 1-3 page brochure site | £350 – £900 |
| Small business site (up to 5 pages) | £490 – £1,200 |
| Larger business site (up to 20 pages) | £1,190 – £3,000 |
| Starter eCommerce store | £590 – £2,500 |
| Growth eCommerce store (multi-category) | £2,500 – £5,000+ |
These ranges cover custom-designed sites built by a UK agency or freelancer — not marketplace templates, and not overseas outsourced builds, both of which come with their own trade-offs in quality and support.
Why the same "type" of site can vary within its range
Within each category, price still moves based on how much revision time is included, whether copywriting is done for you or you supply it, and how fast you need it delivered. Rushed turnaround almost always costs more.
Hidden costs that catch people out
The build price is rarely the full story. Before you sign off on a quote, check whether these are included or extra:
- Hosting and domain — some agencies bundle a year free, others bill separately from day one.
- Stock photography or a shoot — decent imagery can add hundreds of pounds if it's not already included.
- Copywriting — writing the actual page content yourself saves money; having it written for you doesn't come free.
- SEO setup — a site that looks great but isn't optimised for search won't generate traffic on its own.
- Ongoing maintenance — updates, security patches and content changes after launch are a separate, recurring cost.
A website that's £200 cheaper but missing SEO setup, mobile optimisation or basic support usually ends up costing more once you factor in the rebuild you'll need in a year or two.
How to compare quotes properly
Ask every agency the same three questions: how many pages and revision rounds are included, whether copywriting and images are covered, and what happens after launch if something breaks. Comparing answers to those three questions tells you far more than comparing headline prices alone.

How much does a basic website cost in the UK?
A basic 1-3 page website in the UK typically costs between £350 and £900, depending on design complexity and how much content needs writing.
Why do website quotes vary so much between agencies?
Quotes vary because of what's included: some prices cover design only, while others include copywriting, SEO setup, stock imagery, hosting and ongoing support. Always ask exactly what's in the number.
Is it cheaper to build a website myself?
DIY builders can be cheaper upfront, but they cost time, and most business owners end up paying a developer eventually to fix design, speed or SEO issues a template couldn't solve.
What ongoing costs should I budget for after launch?
Beyond the build, budget for hosting (from around £3/month), a domain (from around £10/year), and either your own time or a maintenance plan (from £45/month) for updates and security.
