If you've asked three UK web designers for a quote in the last 12 months, two of them said WordPress and one of them said Astro. The Astro one is right.
This is what's actually happening in UK small-business web design in 2026, and how to find an Astro web designer who knows what they're doing.
What is Astro?
Astro is a static site framework. It takes your content, your design, and your data, and produces plain HTML files that load instantly, no PHP, no MySQL, no plugin marketplace, no admin login that gets brute-forced at 3 a.m. The site itself is just files; the editing happens through a separate CMS (usually Sanity, Contentful, or Keystatic) that your team logs into.
For most UK small business sites, 5 to 20 pages, marketing-focused, with a blog. Astro is the right tool.
Why UK small businesses are leaving WordPress for Astro
1. Speed (and ad cost)
Lighthouse 95+ is the default on Astro builds, not the exception. WordPress sites with the average plugin stack land at Lighthouse 40–60. Why does this matter for a UK small business?
- Google rewards fast sites, Core Web Vitals is a ranking factor and your Astro competitor will outrank you for the same content.
- Paid ads cost less on fast landing pages, Meta and Google both apply landing-page experience scores. A Lighthouse-95 Astro page can pay 20–40% less per click than the same offer on a WordPress page.
- Mobile users actually wait, the average UK shopper bounces if a page takes >3s on 4G. WordPress hits that ceiling before the hero image loads.
2. No plugin sprawl
The average WordPress small-business site runs 28 plugins. Each one is a security surface, a performance tax, and a future compatibility risk. Astro has none.
Real cost: a WordPress site we audited last quarter had a single broken plugin causing 2.4 seconds of layout shift. The fix took 3 hours and £255 of agency time. The Astro equivalent would have been impossible to break in that way, the plugin doesn't exist as a category.
3. No monthly maintenance fees that go nowhere
WordPress hosts charge £15–£60 a month for "managed hosting", most of which is keeping the plugin stack patched, the database optimised, and the security WAF blocking the daily login-brute-force attempts. Astro deploys to Cloudflare Pages or Vercel for £0–£20 a month, fully static, nothing to maintain. Over 5 years that's £900–£3,600 saved per client.
4. Real CMS without the vulnerability
The argument for WordPress was always "non-technical clients can edit content." That's still true, but it's also true on Astro with a modern headless CMS. Sanity, Keystatic and Contentful all give your team a clean editing UI without exposing the website itself to the public internet. Best of both worlds.
Where Astro isn't the right pick
Astro is wrong for:
- Sites with 1,000+ frequently-updated pages (e.g. news sites, large directories), build times become an issue
- Heavily logged-in experiences (members-only platforms, SaaS dashboards), use Next.js instead
- Sites that genuinely depend on a WordPress plugin (e.g. WooCommerce-specific integrations), stay where you are
For 90% of UK SME briefs, marketing site, blog, contact form, maybe basic commerce. Astro is the right tool.
How to find a UK Astro web designer who actually knows the framework
The talent pool is small. Filter aggressively:
- Ask for 5 production Astro sites in their portfolio, not demos, not personal projects. Real client sites, real domains.
- Lighthouse-test those sites yourself, paste the URL into PageSpeed Insights. Real Astro work hits 95+ on mobile. If it's 70 the framework was misused.
- Ask which CMS they pair Astro with, "Markdown files in the repo" is fine for technical clients, terrible for non-technical ones. Look for Sanity, Keystatic, Contentful or Storyblok.
- Ask about content collections, partial hydration and view transitions. Astro-specific concepts. If the designer can't articulate them, they're WordPress people who skinned a brochure site once.
- Ask about migration from WordPress, most UK Astro briefs include a migration. The designer should have a clean playbook for it (URL preservation, 301 redirects, content extraction).
