UK switching guide
How to switch UK card machine provider.
Most UK SMEs stay with their first card machine provider for years past the point where the deal stopped being competitive. The reason is usually fear of downtime, not the contract. This is the 7-step playbook for switching cleanly without losing a single sale.
In one sentence
Get the new terminal installed and tested in parallel before you give notice on the old one; run both for the notice period; only return the old terminal after the cancellation effective date.
The 7 steps
- Read your current contract. Find the end date, minimum-term clause, and notice period (usually 30-90 days). Switching before the end date may trigger early-termination fees of £500-£2,000.
- Get 3 quotes. Calculate your current effective rate (total fees ÷ total card volume last quarter). Compare against 3 quotes from UK-licensed providers. Don't compare headline rates, compare effective rates including monthly minimum, terminal rental, AMEX premium, PCI fee, and the interchange-plus pricing structure.
- Pick the right time. Avoid month-end (busiest) and VAT quarter close. Aim for a Tuesday or Wednesday at the start of a month.
- Apply to the new provider. Send the application + Companies House number + last 3 months of business bank statements + last quarter of card-payment statements. Acquirer underwriting takes 2-7 days. Facilitator onboarding takes hours.
- Receive + test the new device. When the new terminal arrives, do a £1 self-test against your own card. Confirm settlement appears in your bank account the next working day. Do NOT cancel the old terminal yet.
- Give written notice to the old provider. Email AND post (recorded delivery). Quote your merchant ID and the notice-period clause. Keep proof of delivery, providers regularly claim notice was "not received".
- Run both for the notice period, then return the old terminal. Keep the old terminal connected as backup until the cancellation effective date. Return it via the prepaid return label or recorded delivery within the window stated in the contract. Lost or late returns are charged at £150-£400.
Common mistakes
- Cancelling before testing. You lose sales if the new terminal arrives faulty.
- Verbal notice. Always written. Providers ignore verbal cancellation.
- Mid-month switch. Disrupts your monthly reconciliation.
- Comparing headline rates. A 1.5% headline can be 2.4% effective once you add monthly minimum, terminal rental, AMEX, PCI.
- Not returning the old terminal. Providers charge full device cost (£150-£400) for non-return.
If you're locked into a contract you can't escape
Long minimum terms and early termination fees are the clauses that trap most merchants. Our card machine contract traps guide breaks down the three traps (lock-in, ETF, the "free" machine catch) and how to read them before you sign.
Some UK acquirer contracts have 36-48 month minimum terms with severe early-termination clauses. If you're trapped, two routes:
- Wait for the notice window. Most contracts auto-renew 30-90 days before end. Mark the date in your calendar today and serve notice the day the window opens.
- Negotiate down. Call the provider, say you're switching, ask for a price match. Acquirers retain at much lower rates than they quote new customers. 30-50% discounts are normal at renewal threat.
