Bacs, CHAPS and Faster Payments: UK bank transfers explained

Part of How payments work. Start with the main guide: How a card payment works: authorisation, clearing and settlement

Every business that takes card payments also lives with bank transfers. Staff are paid by one, suppliers by another, and the money from card sales arrives in the bank account by a third. In the UK these go by three names that people often mix up: Bacs, CHAPS and Faster Payments.

This guide explains what each one is, how they differ on speed, limits and cost, and how they compare with the equivalents in the US, Australia, New Zealand and South Africa. It is written for payment consultants, so it also covers why bank transfers matter when a merchant asks about getting paid faster or avoiding card fees.

What is a Bacs payment?

A Bacs payment is a bulk electronic payment in the UK that takes three working days to complete. It is the scheme behind Direct Debits and Direct Credits, which businesses use for payroll, supplier runs, rent and regular collections. Payments are sent in batches, not one at a time.

The three days are a cycle. A business submits the payment file on the first day. It is processed on the second. The money reaches the recipient's account on the third. That gap gives the sender time to cancel or amend a file before funds move.

Bacs has two parts. Direct Credit pushes money out, for example paying wages. Direct Debit pulls money in with the payer's permission, for example a monthly subscription, and is protected by the Direct Debit Guarantee.

What are Faster Payments?

Faster Payments is the UK's near-instant payment system. It started in 2008, runs every day of the year at any hour, and processes payments in real time. Pay.UK reports about 5.55 billion payments worth roughly £4.84 trillion in 2025.

The scheme limit is £1 million per payment, though each bank sets its own lower limits by channel and account type. When someone sends money from a banking app and it arrives in seconds, that is usually Faster Payments. Standing orders and most online transfers use it too.

What is a CHAPS payment?

CHAPS is the UK's same-day system for high-value payments. It is run by the Bank of England, works on business days only and has no upper limit on payment size. It is the usual choice for property purchases, large business payments and anything that must arrive the same day with certainty.

CHAPS is the most expensive of the three for the sender, because banks usually charge a fee for each payment. Faster Payments is often free or low-cost for customers and has a £1 million cap, so most people use CHAPS only when the amount or the urgency requires it.

How do Bacs, CHAPS and Faster Payments compare?

Bacs versus CHAPS comes down to speed and size. Bacs is slow and cheap and suits regular, planned payments. CHAPS is fast and costly and suits urgent, large ones. Bacs versus Faster Payments is mostly a speed question, since Faster Payments is now free or low-cost for many customers and has largely replaced Bacs for one-off payments.

Which should a business use?

How do these systems affect card settlements?

A merchant's card money has to reach their bank account somehow, and in many cases it arrives by one of these rails. A provider that settles by Bacs may take more days to deliver funds than one that settles by Faster Payments. Providers also differ on whether they pay out every day, on set days or on request.

That is why a merchant who says "money arrives late" may have a settlement issue and not a rate issue. When you read a statement, compare the settlement date with the date the money reached the account. See how a card payment works for where settlement sits in the payment journey. Some providers offer faster funding for a fee, which belongs in the cost comparison.

What are the equivalents in other countries?

Every market has the same three ideas: a slow batch system, a fast real-time system and a high-value same-day system. The names and limits differ.

United States

ACH is a batch system, like Bacs, used for payroll, bill payments and Direct Debit style collections. Same Day ACH has a limit of $1 million per payment, and Nacha has scheduled a rise to $10 million, with an effective date of 17 September 2027. Wire transfers are the high-value same-day option and usually cost the sender a fee. RTP and FedNow are the real-time options, each with a $10 million per-payment limit.

Australia

The New Payments Platform, run by Australian Payments Plus, makes payments in real time at any hour. Osko is a service built on top of it, and PayID lets people pay to a phone number or email instead of an account number. Limits are set by each bank, and some banks hold a first payment to a new payee for a time. BECS Direct Entry is the older batch system, and payments to banks outside the real-time platform can take up to three working days. BPAY is a separate service for paying bills by biller code.

New Zealand

Ordinary transfers, direct credits and Direct Debits run through BECS, which New Zealand shares with Australia. Banks now run batches every day of the year, so transfers between banks can complete on weekends and public holidays, though they are still batches and not real-time. High-value same-day cleared payments are used for things like property settlements, cost a fee and cannot be reversed. Transfers within the same bank post almost instantly.

South Africa

EFT is the standard bank transfer and usually takes one to two business days between banks. Real-Time Clearing, known as RTC, delivers funds within minutes and has a higher limit on business days than overnight or at weekends. PayShap is a newer real-time scheme that lets people pay with a phone number or a ShapID. Its limit has been reported at up to R50,000 per payment, though banks may set lower caps, so check with the bank. PASA treats payments up to R5 million as low-value and routes larger ones through SAMOS.

Why do bank transfers matter when talking about card fees?

Merchants sometimes ask whether they can avoid card fees by taking bank transfers, and more markets are adding "pay by bank" options at checkout. Transfers can cost the business less per payment than cards, which is why the question is fair. But they differ in ways that matter.

• No chargeback rights. A bank transfer is a push payment. Once sent it is hard to reverse, so the customer has fewer protections than on a card, as covered in refunds, chargebacks and turnover.
• No automatic reconciliation. The merchant has to match each transfer to an order, which takes time unless a payment provider does it.
• Customer habit. Many customers prefer cards because of rewards, protection and convenience.
• Fees still exist. Providers that offer pay by bank charge their own fees, which should go through the same statement comparison as card fees.

A consultant should not dismiss transfers, and should not oversell them. They suit larger, planned payments such as invoices and deposits, and cards suit everyday retail. For the terms used in these conversations, see the payment terms glossary, and add any extra funding or transfer fees to the calculator.

What is the difference between Bacs and CHAPS?

Bacs is slow, cheap and suits regular planned payments, taking three working days. CHAPS is same day, has no upper limit and usually carries a fee, so it suits urgent or high-value payments such as property purchases.

What is the difference between Bacs and Faster Payments?

Faster Payments moves money in seconds, any time, up to a scheme limit of £1 million. Bacs takes three working days and runs on working days. Faster Payments suits one-off transfers, and Bacs suits planned batches like payroll.

Is CHAPS faster than Faster Payments?

What is the ACH equivalent in the UK?

Bacs is the closest equivalent to ACH. Both are batch systems for payroll and Direct Debit style payments, though Same Day ACH is faster than Bacs. The UK equivalents of wires and real-time payments are CHAPS and Faster Payments.

How does my card sales money reach my bank account?

Your provider settles card sales into your bank account, often by Bacs or Faster Payments in the UK. The rail and the provider's payout schedule decide how many days it takes, so check both when comparing providers.

Figures in this guide are examples to show the method. Fees, rules and rates change, so check your own statement, contract and current rules before you decide. This is general information, not financial or legal advice.
