What a specialised agency brings to a UK Shopify store
The UK market has its own rules, and a store that ignores them loses conversions quietly. We set up the payment methods British shoppers reach for first: cards, Apple Pay and Google Pay, plus Klarna and Clearpay at checkout.
We configure VAT-inclusive pricing in GBP, add the company details the Companies Act 2006 requires in your footer, and build cookie consent that meets ICO guidance rather than the EU template.
Delivery is where UK stores win or lose the sale. We integrate Royal Mail, DPD and Evri, set free-delivery thresholds where the data says they work, and add Click & Collect if you have shops.
UK shopping habits every Shopify merchant should design for
The UK is Europe’s most mature e-commerce market and most of its orders are placed on a phone, so we design the mobile product page first and the desktop one second.
British shoppers read reviews before they buy and abandon carts over delivery costs more than anything else. Reviews near the buy button and delivery pricing on the product page both move the numbers.
Cross-border shopping is less common here than on the continent, so a UK store needs to feel British: GBP, UK spelling, UK delivery promises, and a checkout that does not ask for a state.
Why UK brands pick us over a freelancer, a big agency or a hire
None of these are bad options. They just cost you something we don’t.
Four steps, and you can see every one of them
- 01A 30-minute callWe look through your store before the call and come with questions about what is slowing it down, so the time goes on your store and not on a pitch.
- 02A written scope with a fixed priceWhat we will build, what it costs and when it starts, on one page. Most projects start within 3–5 business days of you saying yes.
- 03Build in the openA shared Slack channel, a staging store you can click through at any point, an update at least every 48 hours and a call every week.
- 04Launch, then stay closeWe launch, watch the first weeks of data and fix what the data says to fix. Most clients keep us on for the next thing.
