What a £500 vs £5,000 Cardiff Web Design Actually Looks Like

Open a £500 site and a £5,000 site side by side on a desktop and they will both look fine. The differences live where you do not look — in the page weight, the structure of the copy, the way Google reads it, and what happens the week after launch when something needs to change.

This is a line-by-line comparison of what each tier actually buys you in Cardiff in 2026.

The screenshot test is misleading

A £500 site can have a beautiful hero image. A £5,000 site can look identical at a glance. Stock photography is cheap. Free Tailwind templates are good. Modern themes hide low-budget builds well.

What the screenshot does not show:

• How fast the page loads on a 4G connection in a coffee shop
• Whether the contact form actually delivers email reliably
• Whether Google can read the structure or whether it sees one giant blob
• Whether someone who is not the original developer can update it next year

Those are the £4,500 of difference. None of it is visible until something needs to work.

The £500 site

A £500 budget in Cardiff usually buys:

• A single-page site or 3-page max
• A free or low-cost theme on Wix, Squarespace, or a basic WordPress install
• Stock images and lightly customised colour palette
• A standard contact form using the platform’s built-in handler
• Whatever SEO the platform does automatically (which is, charitably, “some”)

Done well, a £500 site is genuinely fine for a sole trader who needs a credible online presence and gets most of their leads from referrals or Google Business Profile. The site backs up the business; it does not run it.

Done badly, a £500 site is built in three hours by someone who will not return your call when the form stops working in November.

The £1,500 site

This is the volume range for Cardiff small businesses with one or two services. At £1,500 you should expect:

• Properly written page copy informed by your actual customers, not lorem-ipsum-with-business-words
• A 5–8 page site with intentional information architecture
• Mobile-first design tested on real devices
• Basic on-page SEO — title tags, meta descriptions, alt text, heading hierarchy
• A faster underlying stack — usually static-generated rather than database-driven
• Reliable form delivery via something like Resend or Brevo, not the platform default
• A 30-day post-launch fix window

This is the price band where the site starts pulling its weight. It is not just a brochure; it is a small acquisition channel.

The £5,000 site

At £5,000 in Cardiff in 2026, you should be getting genuinely different work, not just more of the same. Expect:

• Discovery that names a specific commercial outcome (“3 enquiries a week at £400 average ticket”)
• Custom design rather than a styled template
• Conversion-focused copy with at least one round of testing
• A booking, payment or lead-routing integration that actually works (Calendly, Stripe, HubSpot, etc.)
• Schema markup for local business + relevant categories
• Page speed in the 90+ range on Lighthouse for both mobile and desktop
• Analytics set up to measure the outcome named in discovery
• A 90-day support window with a defined response SLA

If you are paying £5,000 and not getting that list, you are paying agency rates for a £1,500 build with a markup.

What the gap actually buys

The honest summary of the £4,500 difference:

The £500 site is appropriate when the website is not the lever. The £5,000 site is appropriate when the website *is* the lever.

Where Studio 72 sits

Studio 72 does not quote in this range at all, because there is no build fee:

In the terms of this article, the free landing page punches at roughly the £800–£1,200 band on deliverables — real copy direction, custom design, proper performance, schema — with the build cost taken out entirely and a cancellable monthly figure in its place. It is one page, so it is not competing with the £5,000 multi-page builds above; those exist here too, but as scoped work priced on application. Integrations beyond a website (booking platforms, portals, internal tooling) are custom software, scoped separately from £8,000.

The decision

Pick a price band based on what the website needs to do, not on what looks impressive in a quote. A £500 site doing one job well beats a £5,000 site that no one quite uses.

Run /audit to see whether your current site is at the price band’s expected performance, or see what the free build actually includes at /pricing.
