The ONS Retail Sales Index online share is published as a share of total UK retail sales, not of all consumer spending. It excludes services bought online (transport, hospitality, subscriptions, digital goods that are not classified as retail). The figure on this page is therefore a conservative read of how much UK consumer spending is online; the true total digital share including services is higher.
Card-not-present fraud as reported by UK Finance covers card-payment fraud only and does not include Authorised Push Payment scams committed during online purchases (those sit in the APP fraud line in our payment fraud statistics page). Readers comparing 'online fraud' across sources should check whether APP is included in the figure.
By-sector chargeback rates are not consistently published in the UK. Card schemes publish merchant-monitoring thresholds (typically 1% of transactions); UK Finance does not currently publish per-sector chargeback ratios. Any figure in this section that is not labelled with a primary source carries a confirmation flag rather than asserted as verified.
Processing fee ranges on this page are at market-overview level. The full per-acquirer comparison sits on the card-processing-fee benchmarks page, which is the canonical reference for merchant pricing.
