The answer, increasingly, looks like yes. Research across ecommerce benchmarking, consumer privacy surveys, and payments behaviour consistently points to the same conclusion: every extra field, every mandatory account creation, and every uninvited data request at checkout increases the probability that a ready-to-buy customer simply walks away. For UK retailers competing in a tightening consumer economy, that is not a UX problem — it is a revenue problem.
The scale of that leakage is striking. Global online cart abandonment has remained stubbornly above 70% for years, and the reasons are not primarily about price. Friction, complexity, and data demands now rank alongside unexpected costs as the dominant drivers of drop-off. British retailers, operating in a market with strong GDPR protections and a particularly privacy-conscious public, face this challenge in an even sharper form.
Checkout abandonment costs retailers billions annually
Mandatory account creation is one of the most damaging single points of friction in any checkout flow. According to 2026 research summarising data from the Baymard Institute, 26% of online shoppers abandon their cart specifically because they are forced to create an account — making it one of the top three abandonment triggers, alongside surprise fees and confusing navigation. That is not a marginal cohort of edge-case users; it represents more than one in four potential transactions simply evaporating at the final stage.
The revenue implications compound quickly at scale. A mid-size UK retailer processing tens of thousands of transactions per week loses a meaningful proportion of that volume every time a form feels too long, too intrusive, or too demanding. What makes this particularly difficult is that many of these data requests — loyalty enrolment, marketing consent, full contact profiles — serve the retailer’s CRM strategy, not the customer’s need to complete a purchase. That misalignment is where conversions die.
Why consumers push back on data collection
Consumer resistance to data collection is not passive or accidental. Surveys consistently show that shoppers are actively managing their digital privacy, not just expressing abstract concern about it. According to data privacy research compiled by CookieYes in 2025, 81% of internet users want to know how their data is being used, and 61% updated or reviewed their privacy settings in the previous twelve months. These are not hypothetical preferences — they are active, deliberate behaviours that play out directly at checkout.
The same dynamic surfaces in adjacent digital sectors. The growth of no KYC casinos as a documented consumer preference illustrates just how sensitive users are to identity verification demands in online environments — even when the stakes are relatively modest. Telecom providers, fintech apps, and VPN services face the same pushback: excessive verification steps are increasingly seen as security risks rather than safeguards.
This sensitivity matters even more in the UK context. Around 60% of consumers believe companies routinely misuse their personal data, which means that every non-essential field in a checkout form — a secondary phone number, a date of birth for a standard order — is encountered with a degree of scepticism that directly undermines conversion. UK retailers asking for that data without a compelling, visible reason are not just adding friction; they are actively eroding trust at the moment it matters most.
Frictionless models reshaping purchase expectations
Consumer expectations have shifted, and the benchmark for an acceptable checkout experience has moved with them. Shoppers now arrive at the payment stage having used Apple Pay, Google Pay, and one-click checkout tools across multiple platforms — experiences that require almost no manual data entry at all. When they then encounter a retailer demanding a full registration form before confirming an order, the contrast is jarring.
According to Rokt’s 2026 ecommerce expectations report, addressing checkout usability issues — including forced account creation — could increase ecommerce conversion rates by up to 35%. That figure represents a substantial commercial upside that is already available to retailers willing to simplify their checkout flow, without requiring new product development, additional marketing spend, or price adjustments.
What retailers can learn from leaner verification
The principle emerging from both retail best practice and adjacent digital sectors is the same: collect only what is necessary to complete the transaction, and move everything else out of the critical path. Loyalty sign-ups, preference surveys, and marketing consent can be offered post-purchase, when the customer has already converted and is likely in a more receptive mindset. Keeping the checkout lean protects the transaction without sacrificing the longer-term data relationship.
For in-store retailers, the equivalent dynamic plays out at the till. Pushing email capture or loyalty enrolment during payment — particularly for low-value purchases — can slow down the transaction and feel disproportionately intrusive. Shopify’s 2026 in-store trends analysis recommends that retailers “remove checkout bottlenecks” and ensure any data collection is transparent, clearly optional, and demonstrably valuable to the customer. The direction of travel is clear: data collection should follow the sale, not obstruct it.
UK retailers with strong first-party data ambitions do not have to choose between knowing their customers and converting them. The two goals are compatible — but only when the sequence is right. Reduce friction at the point of purchase, complete the transaction, and then build the data relationship from a position of goodwill rather than coercion. That shift in approach is increasingly the difference between retailers growing their conversion rates and those quietly watching revenue drain away at the final step.
