The Short Version

Square Reader costs £19 plus VAT and takes chip & PIN, contactless, Apple Pay, and Google Pay. It charges a flat 1.75% on every UK card payment in person.

No monthly fee, no contract. The Square POS app that drives the reader is free, with unlimited staff logins, inventory, and a built-in CRM.

The decision tension is simple. That 1.75% rate never drops, whatever your turnover.

A business processing £30,000 a month pays the same percentage as one processing £3,000. Square is excellent value at low volume and progressively expensive higher up.

Dojo, Worldpay, and Paymentsense will usually negotiate rates of roughly 0.7%–1.4% for established businesses, traded against a monthly fee. That’s the key trade-off. Our card machines comparison runs through the main negotiated-rate providers side by side.

Below roughly £3,000–£5,000 a month in card turnover, Square is almost always the cheapest option once you include the monthly fees of a traditional merchant account.

Above that band, the maths shifts. If your card takings are growing past £5k a month, start modelling a negotiated provider before your next VAT quarter hits.

For mobile traders, market stalls, pop-ups, and sole traders taking card payments occasionally, Square is the default we’d check first.

How Square Works

Square entered the UK in 2017. It combines card acceptance, POS software, online store tools, and invoicing into one account.

The UK business sits behind squareup.com/gb and is authorised to provide payment services locally. We verified current pricing and product details from squareup.com/gb in April 2026.

The Reader is the smallest and cheapest piece of Square hardware. It’s a pocket-sized contactless and chip device that pairs to an iOS or Android phone over Bluetooth 5.3.

The phone runs the free Square POS app. That’s what actually rings up the sale, takes the PIN if one is needed, prints or emails the receipt, and talks to Square’s payment network.

If you already carry a phone you trust, you have most of the hardware. The £19 reader is the only extra kit you need to start taking cards.

Funds land in your UK bank account the next working day by default, with instant transfer available for an extra 1.5%.

The Main Strengths and Weaknesses

Strengths
  • One flat 1.75% rate on UK cards in person, across every device Square sells
  • No monthly fee and no contract on the Free plan
  • Free Square POS app with unlimited staff logins, inventory, CRM, and invoicing
  • £19 + VAT hardware cost, one of the cheapest entry points to card acceptance in the UK
  • Next-day settlement including weekends and bank holidays
  • Accepts American Express at the same 1.75% rate, unlike some traditional acquirers
Limitations
  • The 1.75% rate doesn’t reduce with volume unless you qualify for custom Premium pricing (£200k+ annual card turnover)
  • Non-UK cards carry an extra 1.5% in person, taking the effective rate to 3.25%
  • Instant transfers cost 1.5%, which compounds to an effective 3.25% on each in-person sale if used every time
  • Reader has no screen or keypad; the customer enters PIN on the merchant’s phone, which some staff find awkward
  • Keyed-in and invoice transactions cost 2.5%, noticeably higher than the in-person rate
  • Account reserves and fund holds are possible, particularly on newer accounts with unusual transaction patterns

Square Reader

Square Reader is the cleanest entry point to card payments in the UK: £19 of hardware, a free POS app, and one 1.
Best for: Sole traders, mobile businesses, market stalls, and part-time operators taking under roughly £3,000–£5,000 a month in card payments who want one flat rate and no contract.
Watch out: Non-UK cards are charged 1.75% + an extra 1.5% in-person (3.25% total), which Square doesn’t advertise prominently. Tourist-heavy businesses need to budget for it.
Not ideal if: Fixed retailers and hospitality venues processing five figures a month in card turnover, where Dojo or Worldpay’s negotiated rates usually undercut Square’s 1.75% flat fee.

Square’s Fees and Costs

Card Payment Fees

We confirmed the current fee schedule from squareup.com/gb in April 2026. In person, UK-issued cards cost 1.75% of the transaction value.

That rate covers chip & PIN, contactless, Apple Pay, and Google Pay, across Reader, Terminal, Register, and Handheld. A £40 sale costs you 70p in fees.

A £2,000 day of 50 transactions at £40 average costs £35 in fees total. That’s the headline number most reviews stop at.

Move off the in-person rate and costs rise. This is where most buyers get caught out.

Keyed-in and virtual terminal transactions are 2.5%. Online card payments are 1.4% plus 25p per transaction. Clearpay (Square’s buy-now-pay-later option) is 6% plus 30p.

Non-UK cards in person carry an extra 1.5% surcharge, taking the rate to 3.25%. If your customer mix leans on international tourists, that adds up: £5,000 a month on non-UK cards costs you roughly £75 more than on UK cards alone.

That’s the key constraint for tourist-facing businesses.

From the worked examples we ran against published Dojo rate cards, there’s a practical breakeven against traditional merchant accounts.

At £2,000 a month in card turnover, Square costs £35. A Dojo-style setup at roughly 1.2% plus a £15 monthly fee would cost £39. Square wins.

At £6,000 a month (150 transactions at £40), Square costs £105; the same Dojo setup costs around £87. Past about £5,000 a month, the flat rate starts to bite — we’d switch reviewers at that point to a monthly-fee merchant account.

Hardware Costs

The Reader itself is £19 plus VAT, paid once. There’s no rental model and no return of the hardware when you leave.

Square runs interest-free instalments on orders between £29 and £3,000 over three, six, or twelve months, subject to credit approval.

Terminal works out at around £25 a month over six months; Handheld at around £29 a month over six months. If you’re fitting out a shop or restaurant, that spreads the cash outlay without adding a monthly software fee.

No hardware discount for processing more: the rate stays flat regardless.

If you need more than the basic Reader, the range steps up cleanly. The Terminal is £149 plus VAT and runs standalone with a built-in receipt printer.

The Handheld is £169 plus VAT and adds a barcode scanner for table or floor service. The Register is £699 plus VAT (or £59 a month for 12 months) and is a fixed counter unit with two touchscreens.

Monthly Fees and Contracts

No monthly fee on the Free plan. No contract, no minimum term, no early exit charge.

If you stop taking payments for six months, Square simply sits idle until you use it again. That’s the core of the pitch against traditional acquirers.

For seasonal traders (summer markets, Christmas fairs, event-led work) that matters: no standing fee during the quiet months.

Square Plus costs from £29 a month and adds sector-specific POS features: course management for beauty, floor plans for restaurants, appointment-book depth for services.

Square Premium is custom-priced and only offered to businesses processing over £200,000 a year in card turnover. Premium is where negotiated rates become possible.

Below that threshold, 1.75% is what you pay.

Square’s Payouts and Transfers

How Standard Payouts Work

We verified Square’s settlement policy from their UK help pages in April 2026. Any transaction processed before 00:00 GMT lands in your UK bank account the next calendar day, weekends and bank holidays included.

That’s next-day settlement for most trading patterns, since the cutoff is midnight rather than an afternoon deadline. A Saturday market stall sees takings on Sunday.

Settlement including weekends is rare: most rivals exclude Saturdays.

If you need cash from weekend sales to cover Monday payroll or a supplier invoice, Square’s weekend-inclusive next-day payout is the feature to check against the rest of the market.

Payments taken after 00:00 GMT move to the day after. In practice that only affects late-night bars and 24-hour businesses whose sales cluster after midnight.

Square’s cutoff can be adjusted in account settings to fit trading hours.

Instant Payouts

Yes, for a fee, and it’s one we’d suggest using sparingly. Instant Transfer costs 1.5% of the amount moved and arrives within about 20 minutes.

You need to keep at least £15 in the Square balance after the fee. New sellers are capped at one transfer per day up to £750; established sellers get up to £3,500 in a 24-hour window.

The 1.5% instant transfer fee is the hidden cost of same-day cash.

The number to watch: 1.5% on top of 1.75% is an effective 3.25% per sale. A business using instant transfer on every transaction has quietly moved above the rates Dojo or Worldpay would quote.

That sits very close to what SumUp or Zettle charge as their headline figure on standard settlement. Instant transfer is best used selectively, not as the default.

Using the Square Reader

Payments It Accepts

The Reader takes chip & PIN, contactless, Apple Pay, and Google Pay. Visa, Mastercard, Maestro, V Pay, Visa Electron, Discover, and American Express all process at the same 1.75% in-person rate.

Contactless limits follow standard UK card network rules. Check squareup.com/gb for the current figure before advising customers.

One behavioural quirk matters on day one. The Reader has no screen and no keypad of its own.

When a chip & PIN is needed, the Square POS app on your phone or tablet becomes the PIN pad, and you hand the phone to the customer.

It works, and PIN entry is PCI-compliant. But staff used to a traditional terminal find the handover unfamiliar for the first week.

If your team is used to handing a traditional terminal to a customer, brief them before go-live. Hand the phone over face-down and hold eye contact until PIN entry completes.

Refunds are processed through the app against the original transaction. The card fees on the original sale are returned to you along with the refund.

Square doesn’t keep the percentage on refunded transactions, which isn’t universal across the industry.

Portability and Reliability

Pocket-sized, lightweight, and charged by USB-C. Battery life covers a normal trading day; heavy users should carry a small power bank.

Bluetooth 5.3 pairing is quick once set up and the reader re-pairs on waking.

Offline mode accepts payments for up to 24 hours without an internet connection. Read the small print here.

Square reserves the right to decline transactions taken offline if the card turns out to be declined when they reach the network.

For low-value, low-risk transactions that’s a non-issue. For occasional high-ticket sales in a marquee with no signal, treat offline acceptance as a calculated risk.

The UK-activated Reader is country-locked and will not work if you take it abroad. A separate device and account is needed for other markets.

The Square App and POS System

What the Core POS Includes

The free Square POS app covers more ground than most paid competitors we’ve looked at.

Unlimited staff logins with roles and permissions, inventory with low-stock alerts, a customer directory with purchase history, and digital gift cards.

Real-time sales reporting is built in, along with an invoicing module that handles recurring bills and auto-reminders.

If you’re running shift rotas and need to see staff-level sales at month end, the free tier includes what Zettle and Shopify POS put behind subscription tiers.

For comparison, Shopify POS, Zettle Pro, and most traditional terminal-vendor software gate equivalent features behind subscription tiers.

Square’s pricing logic is that the 1.75% transaction fee covers the software too.

Upgrades and Specialist POS Options

Square sells sector-specific POS apps that layer on top of the core Square account.

Square for Restaurants handles floor plans, coursing, and kitchen display integration. Square for Retail adds purchase orders and vendor management.

Square Appointments handles bookings and deposits for beauty, fitness, and services. Square Online is a free website builder with its own payment rate of 1.4% plus 25p.

Pricing on these specialist apps sits under the Plus plan at £29 a month and up. The 1.75% in-person card rate applies whichever specialist app you run on top.

Most small operators don’t need them. They become relevant at the point you have more than one location or more than about five staff.

How Square’s Devices Compare

The Reader is the device we’d point most first-time sellers to if you already have a phone you trust.

It’s also the smallest option for traders who move: markets, pop-ups, mobile services, hair and beauty that travels.

The Terminal at £149 is the right choice when you don’t want to tie up a phone.

It’s standalone, connects on Wi-Fi or Ethernet, prints receipts from a built-in thermal printer, and is the natural fit for a counter in a small shop, a market caterer, or a tradesperson taking payment at the end of a job.

The Handheld at £169 is Terminal-sized with a built-in barcode scanner and integrated camera, aimed at restaurants doing tableside ordering and retail floor walks.

The Register at £699 is a fixed counter unit with two screens (one for staff, one facing the customer). It’s really only needed for busy high-volume venues where the counter never moves.

The Register earns its price for high-traffic counters; the Reader is for everyone else.

Rate across all four: 1.75% in person on UK cards. No discount for spending more on hardware.

Hardware and Accessories

Beyond the core four devices, Square sells a Stand from £79.20 plus VAT that turns an iPad into a counter POS, and a Kiosk from £74.25 plus VAT for self-service ordering.

Receipt printers, cash drawers, barcode scanners, and kitchen display units are sold separately and integrate with Register and Handheld.

The Kitchen Display System runs at £15 per device per month and is aimed at multi-station kitchens that need tickets routed automatically from front of house.

If your kitchen is a single pass with one chef, it’s overspecified. If you’re running a pub with separate grill, fryer, and dessert stations at peak service, it removes the paper-ticket bottleneck.

All accessories share the same account, inventory, and reporting. You don’t pay separate software fees for adding hardware.

Online and Remote Payment Features

Square Invoices is free, unlimited, and includes recurring invoicing, card on file, and auto-reminders.

Square reports that over 75% of Square Invoices are paid within a day. That’s a vendor-reported figure, not independently audited.

Still, it’s consistent with how well invoices perform when the payment link is a tap away for the client.

Payment links are available for sending to customers by email, text, or chat.

The Virtual Terminal lets you key in a card on a browser (useful for phone orders) and runs at the 2.5% keyed rate.

Square Online is a free website builder with checkout, inventory sync, and shipping integration. The online card rate is 1.4% plus 25p per transaction.

If you’re running a mixed business (some in person, some online, some invoiced), Square keeps all three channels on one account and one reporting dashboard.

You don’t need a separate Stripe or Shopify setup unless the website requirements outgrow Square Online.

Reporting and Accounting Features

Reporting is built into the POS app and the web dashboard. You get real-time sales by day, item, category, staff member, and location, plus end-of-day summaries emailed automatically.

Inventory reports track stock levels, sell-through, and low-stock triggers. Customer directory data covers lifetime value, visit frequency, and last purchase.

When you’re reconciling at month end, Square’s Xero integration pulls transactions automatically. No manual exports if Xero is your ledger.

Accounting integrations we verified from squareup.com/gb are Xero, Kashflow, Wix, and WooCommerce.

QuickBooks integration is listed by Square but wasn’t confirmed on their GB pages when we checked.

Check the Square App Marketplace before committing if QuickBooks is a hard requirement.

Sync depth, VAT handling, and whether fees appear as separate line items vary by integration. That matters for VAT-registered businesses: test with a few transactions before trusting the feed at quarter end.

The gap worth naming: there’s no direct Sage bank feed as of April 2026.

If your accountant works exclusively in Sage, you’re looking at a manual CSV export at month end rather than an automatic feed.

Who Square Is Best For

Low vs High Card Turnover

Low-to-mid card turnover, as far as we’ve been able to model it.

The sweet spot sits roughly below £5,000 a month in card takings, where the absence of a monthly fee more than offsets the higher per-transaction rate.

Below £3,000 a month, it’s rarely even close. Square usually wins outright against any merchant account that carries a standing fee.

Past roughly £5,000 a month in card turnover, the 1.75% flat rate becomes the expensive end of the market.

A £20,000-a-month retailer pays £350 a month to Square. A negotiated rate of 1.1% plus a £20 monthly fee would cost £240.

That’s £1,300 a year walking out of the till for the sake of contract simplicity. At those volumes, we’d expect Dojo, Worldpay, or Takepayments to negotiate.

Best-Suited Business Types

Mobile and occasional traders: market stalls, street food, event caterers, mobile beauty, dog groomers, gardeners, driving instructors, and craft fair sellers.

Anyone who takes cards irregularly and can’t justify a monthly fee.

Small shops and cafes in their first year or two of trading, where card turnover is still finding its level.

Square lets you start taking cards immediately for £19 and switch to a negotiated provider later if volumes grow.

Mixed-channel micro-businesses: a Saturday market plus a Shopify-style web presence plus the occasional phoned-in order.

If that’s your setup, Square keeps one account and one reporting view rather than stitching Stripe, a terminal provider, and an invoicing tool together.

It’s a weaker fit for high-volume hospitality groups, multi-site retail with five-figure weekly card takings, or any business whose accountant insists on a live Sage bank feed.

Square’s Customer Service and Reviews

Common User Complaints

The two recurring complaints we see in public Square reviews are phone support wait times and the way Square handles risk holds.

Support is available by phone, chat, and email during UK business hours. Out-of-hours questions sit until the next morning.

If you’re a Saturday trader hitting reader problems at a weekend market, that’s the support gap to plan around. Keep a cash float and a backup method in the van.

Weekend support gaps are the main operational risk on flat-rate readers.

Positive review patterns (editorial judgement, based on public Trustpilot and App Store reviews rather than a survey) highlight the simplicity of pricing, the free POS features, and the speed of getting set up.

Signup is online with no credit check, and most UK sole traders and limited companies are approved within minutes.

Tap to Pay on iPhone and Android means a first payment is possible on the day of signup through the Square POS app, before the physical Reader has arrived.

Account Stability and Support Issues to Know About

Square has a documented but not prominently advertised risk-management practice worth flagging.

Accounts can have a reserve applied (a portion of takings held back) or experience a fund hold if transaction patterns look unusual.

Newer accounts, sudden jumps in average transaction value, and higher-risk MCC codes are the common triggers.

In practical terms, most small traders never encounter this.

Where it bites is unusual events: a new account suddenly processing a single £2,000 sale, or a business category flagged as higher-risk.

If you’re about to take a large one-off payment through a fresh account (a deposit on a wedding cake order, say, or a commissioned job), read Square’s current terms at squareup.com/gb/legal first. A reserve could hold your cash when you need it for suppliers.

Chargebacks are handled through the Square dashboard with evidence uploaded online.

The specific chargeback fee isn’t published on Square’s UK pricing page; check current terms before relying on that figure.

Getting Started with Square

Setup and Approval Process

Sign up at squareup.com/gb with your business details, ID, and a UK bank account for settlement. Order the Reader from the same account for £19 plus VAT. Delivery is usually a few working days; Square sometimes runs overnight delivery on weekday orders.

Most applications are approved the same day. Square’s automated checks handle the majority of UK sole traders and limited companies. More complex structures or higher-risk sectors can take a day or two and occasionally need a manual identity check.

You need to be UK-based, 18 or over, and able to enter legal agreements. Firearms and regulated illegal categories are excluded; we’d point you at Square’s Acceptable Use Policy for the full prohibited list.

Once the reader arrives, you pair it to the Square POS app in about a minute, link your UK bank account for payouts, and take your first payment. There’s no approval queue between payment taken and money arriving. That’s the core of what Square sells.

Square Alternatives

Square isn’t the only flat-rate option in the UK, and it isn’t the best fit for every buying situation. The three alternatives below each solve a specific Square limitation we’ve flagged above.

Instant settlement without a paired phone, card acceptance inside an existing Revolut Business app, or takings that land directly in a Tide account — pick the one that matches your existing banking setup.

If you already bank with Revolut or Tide, their own readers keep payments in one place and save you opening a second account. If you want instant settlement without a phone or an extra wallet, MyPOS is the closest like-for-like comparison to Square Reader.

Best for Instant Settlement
myPOS logo

myPOS Go 2

MyPOS Go 2 solves the two biggest Square gripes for cash-flow-sensitive traders: it works without a paired phone, and funds land in your MyPOS account instantly.
Best for: Traders who want a standalone reader (no phone needed) and want funds in their MyPOS account instantly rather than next day.
Watch out: Funds settle to a MyPOS account, not directly to your bank. Transferring out to a UK bank is an extra step and may have a minimum or fee; confirm at mypos.com.
Not ideal if: Businesses that want to keep money flowing into their existing UK business bank account without an extra wallet in the middle.
Best for Revolut Business Users
Revolut logo

Revolut Reader

If you already use Revolut Business, adding the Reader keeps payments, FX, and expenses in one app with funds arriving instantly to your Revolut balance.
Best for: Existing Revolut Business customers who already run FX, expenses, and banking inside Revolut and want card acceptance in the same app.
Watch out: You need an active Revolut Business account to use the Reader. That’s another account to open and maintain compared to Square’s stand-alone setup.
Not ideal if: Businesses that don’t want to open a Revolut Business account, or those whose accountant works in Sage and needs a direct bank feed.
Best for Tide Account Holders
Tide logo

Tide Card Reader

Tide’s reader is the obvious fit if you already bank with Tide: card takings arrive in the same account your invoices are paid into and your accountant already sees through the Sage feed.
Best for: Tide business account holders who want card takings to land in the same account they already use for invoicing and expenses.
Watch out: A Tide business account is a prerequisite. Rates and any plan-level conditions should be checked at tide.co before ordering hardware.
Not ideal if: Businesses that don’t bank with Tide and don’t want to open a new account to take card payments.
