financeb2bFaster Payments, Bacs and CHAPS: which UK rail your money is actually on
Three names with no European equivalent, used daily by every British business and explained to nobody outside. Picking the wrong one costs either three days or twenty-six pounds.
The United Kingdom runs three domestic payment systems and they are not interchangeable. Faster Payments moves money in seconds or minutes, around the clock, and handles most day-to-day business payments. Bacs is the batch system behind salaries and Direct Debits: cheap, high volume, and on a fixed three-working-day cycle. CHAPS settles same-day for high-value sterling payments such as property completions, and costs materially more per payment. There is no SEPA in Britain: SEPA is for euro, these three are for sterling inside the UK.
The three rails side by side
The practical question is never "which is best" but "which fits this payment". Speed, cost and batch size pull in different directions, and British businesses pick between them several times a week without thinking about it.
| Faster Payments | Bacs | CHAPS | |
|---|---|---|---|
| Speed | Seconds to minutes | Three working days | Same working day |
| Available | 24/7, including weekends | Working days only | Working days, until an afternoon cut-off |
| Typical use | Supplier and ad-hoc payments | Payroll, Direct Debit collection | Property, high-value settlement |
| Volume model | One at a time | Batches of thousands | One at a time |
| Reversible | No | Direct Debits only, under the Guarantee | No |
Scheme characteristics are set by Pay.UK for Faster Payments and Bacs, and by the Bank of England for CHAPS. Individual providers apply their own limits and cut-offs within those rules.
The Bacs three-day cycle, which is where plans go wrong
Bacs is not slow by accident. It is a batch system with a fixed rhythm, and the rhythm is the single most common thing European finance teams get wrong when they take on UK payroll or UK collections.
- Day one — submission. The file goes in before that day’s cut-off. Miss the cut-off by a minute and everything below shifts by a working day.
- Day two — processing. The scheme processes and distributes.
- Day three — settlement. Money reaches the account.
Three working days. A submission on the Thursday before a bank holiday weekend can land the following Wednesday. If staff are paid on the last Friday of the month, the file has to be in on the Tuesday, and the money has to be in your account before that.
Bank holidays differ between England, Scotland and Northern Ireland, which catches out teams who plan against a single UK calendar.
What each one costs through our partner
Scheme costs vary by provider, so the only honest figures are the ones somebody publishes. These are from Gemba’s corporate fee schedule, UK tariff column. A company registered in the EU falls into the EU column, where outgoing UK payments are £2.99 rather than £0.99 and account maintenance is £69 a month.
| Payment | UK tariff | EU tariff |
|---|---|---|
| Incoming UK payment (Faster Payments) | £0.99 | £2.99 |
| Outgoing UK payment (Faster Payments) | £0.99 | £2.99 |
| Incoming UK payment (Bacs) | £0.99 | £0.99 |
| Direct Debit | Free | Free |
| International payment (SWIFT, CHAPS, T2), each way | £26.40 | £26.40 |

See the pricingAnd no, SEPA does not cover Britain
This surprises people, so it is worth stating precisely. The United Kingdom is still in the SEPA scheme area — SEPA membership is about the payment scheme, not about EU membership, and Britain did not leave it. But SEPA is a euro system. A sterling payment inside the UK never travels on SEPA, no matter who sends it.
So a European business dealing with Britain generally needs both: SEPA for the euro side, and the UK rails for the sterling side. That is the practical case for holding both currencies in one account rather than converting every time.
Which one to use
- Paying a supplier, any normal amount. Faster Payments. It arrives while you are still on the phone.
- Paying staff or contractors in a batch. Bacs, submitted three working days ahead. Faster Payments also works but costs per payment and has no batch workflow.
- Collecting regularly from UK customers. Direct Debit, which runs on Bacs. See the separate guide — it does not work like a SEPA mandate.
- A property completion or a same-day settlement. CHAPS, before the cut-off, and budget for the fee.
