How much does a supplement website cost in the UK?

Why quotes vary so much

Ask five agencies to quote a supplement website and the numbers can span an order of magnitude. The variation is rarely dishonesty — it is scope. "A website" can mean a templated brochure, or a custom-designed Shopify storefront with subscriptions, bundles, compliant product pages and structured data. Those are different products that happen to share a name.

Supplement brands carry an extra cost line most agencies never mention because they cannot deliver it: claims compliance. A site that looks beautiful and says unlawful things is not an asset — it is a liability with good typography.

What actually drives the price

• E-commerce depth — checkout, subscriptions, bundles and market/currency setup, not just "pages"
• Custom design versus a template with your logo on it
• Copywriting, and whether anyone qualified reviews the claims in it
• SEO and AI-visibility engineering: structured data, performance, answer-ready content
• Who carries the project — freelancer, generalist agency, or a specialist who has built for your category before

Our pricing, published

We charge a fixed £10,000 for the core build: custom mobile-first design, full Shopify e-commerce, conversion copy with a regulatory claims pass, and launch in around two weeks. Add-ons are published too — £2,500 for the deeper AI-visibility engineering, £2,500 for the full regulatory and labelling review, £59/month for the ongoing care plan.

One mechanic changes the effective price: manufacture with our group after your build and £2,500 comes back as factory credit — so the website effectively costs £7,500 if you build your brand under the same roof that makes your products.

The most expensive website is the wrong cheap one

The costly failure modes we see are consistent: a cheap build that has to be redone within a year; a beautiful site whose claims trigger a takedown, burning the packaging and ad spend attached to them; and a platform choice that cannot do subscriptions, quietly capping lifetime value. Price the rebuild, the takedown and the lost retention into any quote you compare — suddenly the spread between quotes gets much smaller.
