Should I migrate to Hyvä for my UK fashion store?

Almost certainly yes if you’re on Luma. UK fashion shoppers convert dramatically better on fast mobile experiences:

• Lighthouse 95+ on Hyvä vs typically 40–60 on Luma fashion themes — Google ranks fast pages higher for category/PDP queries.
• Hyvä Checkout loads in < 1s — 50% lower bounce vs Magento Luma checkout, especially mobile.
• Klarna / Clearpay widgets render natively without the React/jQuery double-render Luma has.
• Royal Mail / DPD / Evri shipping pickers render instantly, no spinner-on-spinner.

Typical migration timeline: 4–6 weeks. Conversion lift in the first 90 days post-launch is usually 8–25% from speed alone — then optimisation work compounds it. See our Hyvä service page for fixed-price tiers.
