How to Switch Payment Providers UK 2025 | Step-by-Step Guide

Switching payment providers can save UK businesses 20-40% on card processing fees, but many delay switching due to concerns about downtime, paperwork, or exit fees. This guide walks you through the entire process.

Why Businesses Switch Providers

High transaction fees (most common reason)

Hidden charges appearing on statements

Poor customer service or slow support

Outdated equipment needing replacement

Contract auto-renewed without notice

Locked into expensive long-term contract

Timeline: How Long Does Switching Take?

Day 1-2

Compare Providers & Get Quotes

Request quotes from 3-5 providers. Provide your current statement for accurate comparison.

Day 3-4

Review Offers & Choose Provider

Compare total costs (not just transaction fees). Check contract terms and exit policies.

Day 5-7

Submit Application

Complete application with new provider. Documents needed: ID, bank details, business registration, trading history.

Day 8-10

Approval & Equipment Order

Most applications approved within 24-48 hours. New terminals ordered and configured.

Day 11-12

Receive Equipment

Card machines delivered. Test before going live. Training provided by most providers.

Day 13

Go Live with New Provider

Switch on agreed date. Run test transactions. Keep old terminal for 48 hours as backup.

Day 14

Terminate Old Contract

Send termination notice to old provider. Return their equipment. Final statement issued.

Average Switching Time: 10-14 Days

Most switches complete in under two weeks with zero downtime. We handle the coordination between providers to ensure seamless transition.

Dealing with Early Termination Fees

Early termination fees (ETFs) range from £100-£500 depending on your contract. Here is how to handle them:

1. Negotiate Waiver

If you have been a good customer, ask your provider to waive the fee. Success rate: 30-40%.

2. Wait for Contract End

If savings are less than ETF, wait for contract to expire. Check exact end date to avoid auto-renewal.

3. Factor Into Savings

If saving £200/month and ETF is £300, you break even after 6 weeks. Still worth switching.

4. Get New Provider to Cover

Some providers offer to cover your ETF if you sign with them (usually for high-volume merchants).

Complete Switching Checklist

Before You Switch:

Review current contract end date
Calculate actual costs from last 3 statements
Gather business documents (registration, bank details, ID)
Get 3-5 competitive quotes
Read new contract terms carefully

During the Switch:

Test new equipment before go-live date
Train staff on new terminals
Keep old terminal active for 48 hours as backup
Update website/marketing with new payment options
Monitor first week of transactions closely

After the Switch:

Send termination letter to old provider (recorded delivery)
Return old equipment within deadline (usually 14 days)
Request final statement from old provider
Review first month statement from new provider
Calculate actual savings achieved

Zero Downtime Switching

The key to zero downtime is proper planning and coordination. Here is how we ensure you never miss a sale:

Overlap period: We set your new provider go-live date 2-3 days before terminating your old one
Dual terminals: Run both terminals in parallel for 48 hours to ensure new system works perfectly
Weekend switches: Schedule activation on quiet days (Sunday/Monday) to minimize risk
Backup plan: Keep old terminal powered on for first week as emergency backup
Staff training: Train team before go-live, not during busy periods

Common Switching Mistakes

❌ Not reading the new contract

You could be locked into another bad deal. Always read terms, especially auto-renewal clauses.

❌ Focusing only on transaction fees

Monthly fees, authorization fees, and PCI fees can outweigh headline rate savings. Compare total monthly costs.

❌ Switching in peak season

Do not switch during your busiest period. Choose quiet weeks when staff can focus on learning new systems.

❌ Not testing equipment first

Discover faults when you go live, not during quiet testing period. Process multiple test transactions before launch.

❌ Forgetting to notify customers

If your payment methods change (e.g., accepting Amex now), tell your customers so they know.

What Happens to Your Existing Merchant Account?

Your old merchant account will be closed once you switch. Important things to know:

Final settlement can take 2-5 business days after your last transaction
Any chargebacks from old transactions will be deducted from your final payment
Rolling reserve (if you have one) is typically released within 90-180 days
Keep records of your final statement for accounting purposes
Equipment must be returned within deadline or you will be charged
