FAQs
What is the best card machine for self-storage operators in the UK?
The best UK card machine for self-storage operators in 2026 is Stripe Reader S700 (or Tap to Pay for small operators) on Stripe. Subscription billing dominates self-storage revenue. Stripe Billing plus in-person hardware on the same stack handles recurring + walk-in flow.
How much does a card machine cost for self-storage operators?
Hardware runs from nothing (Tap to Pay on iPhone, on a phone you already own) to £229 + VAT (Stripe Reader S700), with SumUp Solo at £79 + VAT and Square Terminal at £149 + VAT. Published pay-as-you-go rates on UK cards are 1.69% at SumUp, 1.75% at Square and 1.75% at Zettle, with no monthly fee; contract providers quote a blended or bespoke rate and usually charge monthly terminal rental instead. Your blended monthly cost depends on card volume and average transaction size, so model it on your own numbers with our fees calculator rather than relying on a flat figure.
What is the average transaction size in this trade?
£40 to £200 monthly subscriptions, on our working estimate. Your own card statements give the real figure, and it matters because percentage fees and fixed per-transaction fees weigh differently on small and large payments.
How much contactless use is typical for self-storage operators?
Low, as most revenue is recurring billing rather than in-person, on our working estimate. Your own card statements show the real split between tap and chip and PIN, which is worth checking before you choose between a phone-paired reader and a standalone terminal.
What should I watch out for when choosing a card machine for self-storage operators?
Cancellation flow scrutiny on subscription chargebacks. Also check the contract length, exit fees, chargeback handling and how quickly money settles into your account.
How we rank
Rankings are built by desk research from each provider's published rates, upfront costs, contract lengths and settlement terms, held in a dated record per terminal (last-reviewed date shown on this page) and re-checked when published pricing changes. We do not hands-on test every device; specs are taken from provider documentation and cited. No provider pays for inclusion or position. MerchantHQ is an introducer. Quote enquiries go to one card-payments broker, Merchant Advice Service, which pays us a fee for each introduction; acquirers do not pay us commission on quote enquiries. That fee never affects a ranking. See our methodology and how we are funded.
