UK searches for "web design company near me" or "e-commerce developer UK" tend to return a mix of large agencies with enterprise pricing and small studios or freelancers with wildly inconsistent quality — and the gap between the two isn't always obvious from the website alone.
For any UK business selling online, GDPR handling is a legitimate filter question, not a nice-to-have. Ask directly: how do you handle cookie consent, and what's your default approach to storing customer data at checkout? A studio that has a clear, specific answer has actually built compliant checkouts before; a vague answer is worth treating as a warning sign, especially for e-commerce.
Evidence of actual UK e-commerce results is worth asking for specifically, not just "have you built a shop before." Organic sales growth, conversion improvements, or a concrete before/after on a real UK retailer's site tells you far more than a list of WooCommerce or Shopify logos on a homepage — plenty of studios have built a storefront; fewer have made one actually perform.
Payment structure and terms deserve the same scrutiny as anywhere else: a fixed quote in GBP after discovery, broken into deposit, milestone, and balance, is the standard that protects a small business from scope creep turning a £3,000 project into a £6,000 one halfway through.
Catalogue and stock-sync complexity is usually the real cost driver for a UK retailer moving online — more than the storefront template itself. A studio that asks about this early, rather than quoting a flat number before knowing your inventory situation, is scoping properly rather than lowballing to win the job.
The shortlist question worth asking every UK studio you're comparing: can you show me a UK e-commerce client where you handled both the build and the SEO, and what happened to their organic traffic afterward. Studios that can answer with specifics, rather than a general "we do SEO too", are the ones actually equipped to grow a shop past launch day.
