BACS vs Faster Payments for Payroll: What UK Businesses Should Use

UK businesses rely on BACS and Faster Payments to run payroll, but neither system was built with flexibility in mind. BACS payment time takes three working days.[¹ Faster Payments has no native batch infrastructure and neither handles international salary payments. When you have a global team, this can add additional complexities to payroll administration.

This article breaks down how both systems work, where each one fits, and how Wise Business helps UK businesses handle the parts of payroll that domestic payment rails can't reach.

What is the difference between BACS and Faster Payments?

Both BACS and Faster Payments move money between UK bank accounts, but they work in completely different ways. BACS is built for volume and predictability. Faster Payments is built for speed.

How BACS works for payroll processing

BACS, which stands for Bankers' Automated Clearing Services, is a service operated by Pay.UK that processes electronic fund transfers. In Q3 2025, BACS processed 1.7 billion payments worth £1,516 billion.²

It runs on a fixed three-working-day cycle:¹

• Day 1: Submit your payment file between 07:00 and 22:30
• Day 2: Recipient banks receive and process the payments
• Day 3: Funds land in the recipient’s account

BACS only runs on banking working days, so weekends and UK bank holidays don't count. For instance, if you submit on a Friday, the earliest your employees get paid is the following Wednesday. Most payroll teams work backward from payday to make sure they hit the deadline with time to spare.

To send BACS payments directly, your business needs a Service User Number (SUN) and a sponsoring bank.³ Smaller businesses usually go through a BACS-approved bureau or payroll provider instead.

How Faster Payments works for business payments

Faster Payments settles individual payments almost immediately and runs 24/7, including weekends and bank holidays. In Q3 2025, it processed over 1.4 billion transactions worth almost £1.3 trillion, up 6.9% in volume on Q3 2024.²

Unlike BACs, you don’t have to submit any file, and there’s no cutoff window. Your bank validates the payment, sends it through the network, and the recipient's bank credits the funds almost instantly. The transfer limit is £1 million per payment, though individual banks set their own lower thresholds based on account type.⁴

One important caveat: once a Faster Payment is sent, you can't recall it. If you send money to the wrong account, recovering it means contacting the recipient's bank directly, for a credit payment recovery.⁵

How do BACS and Faster Payments compare for payroll?

Most UK payroll teams use both systems, switching between them depending on what the payment needs. Speed, cost, and volume all point to different answers at different times.

Before we go into details, here's an overview of how BACs and Faster Payments compare:

Speed and settlement times

BACs payment processing time runs to three working days, which means planning well ahead of pay day. Missing the daily cutoff pushes the entire run back by at least one working day, which is the last thing employees want to hear on a Friday.

Faster Payments settle in seconds with no cutoff. That makes it the right choice for urgent corrections, emergency advances, or off-cycle salary payments that can't wait three days.

Payment limits and transaction caps

BACS handles up to £20 million per transaction, comfortably covering large monthly payroll runs for hundreds of employees in a single file submission.⁶

The faster payments limit is £1 million at the scheme level, with banks often setting lower internal caps.⁴ For most off-cycle or emergency payments, that ceiling is more than enough. For very high-value payroll scenarios, BACS is the better fit.

Cost considerations for businesses

BACS costs between 5p and 50p per transaction,⁷ making it one of the cheapest business payment methods available for bulk payroll in the UK. Many businesses factor this into their payroll processing time planning, running BACS for the bulk of payments and reserving Faster Payments for exceptions.

The cost of Faster Payments depends on your bank and account type. Standard business accounts often include Faster Payments free of charge or bundled into monthly fees, while corporate banking customers can pay up to £0.50 per transaction.⁸

Reliability and processing windows

BACS has a track record built over decades. It's predictable by design, which is exactly what payroll teams need for regular scheduled runs.

Faster Payments is equally reliable and operates with consistent 24/7 uptime. The main risk is human error, because you can't recall a Faster Payment, a wrong sort code, or an incorrect amount, which is much harder to fix than a BACS error caught before the cutoff.

Because neither system handles payments outside the UK, you need a separate solution to pay international employees.Wise Business lets you send payroll to 140+ countries at the mid-market rate with no monthly fee, sitting cleanly alongside your existing BACS setup.

When should businesses use BACS vs Faster Payments for payroll?

The right system depends on the payment method you're using and the amount of lead time you have. Here's how different payroll scenarios apply to each option.

Monthly payroll runs and planned payments

BACS is the standard choice for regular monthly payroll. It handles large volumes cost-effectively, integrates with most payroll software, and processes on a predictable schedule that employees can rely on.

For UK businesses alsomanaging payroll for international employees, BACS handles domestic salaries but leaves overseas payments entirely out of scope. Wise Business handles cross-border payroll in 40+ currencies alongside your domestic BACS run, with no disruption to either process.

Urgent salary payments and corrections

When something goes wrong mid-cycle, Faster Payments sorts it out quickly. A new starter missing from the BACS file, an incorrect amount, or an emergency advance can all reach an employee's account within seconds, at any time of the day or night.

That 24/7 availability also helps businesses in sectors like hospitality, retail, and healthcare, where pay dates sometimes fall on weekends or bank holidays, and waiting until Monday simply isn't an option.

One thing to get right before you hit send: double-check the account number and sort code. A Faster Payment can't be recalled once it's sent, so accuracy matters more here than with BACS.⁵

Handling bonuses and one-off payments

Bonuses paid on the same date as the regular payroll slot into the existing BACS file with no extra setup or cost. For bonuses that need to go out urgently or outside the normal pay cycle, Faster Payments is the simpler option since there's no file to prepare and no cutoff to hit.

For businesses paying bonuses to employees in other countries, neither BACS nor Faster Payments will work. Both systems are UK-only and process GBP exclusively. Wise Businessbatch payments let you pay up to 1,000 recipients across multiple currencies from a single spreadsheet upload, keeping international bonus runs straightforward.

Limitations of BACS and Faster Payments for scaling businesses

Both UK payroll systems work well for domestic salary payments. The gaps show up when businesses grow, hire across borders, or need more flexibility than a fixed three-day cycle allows.

Batch inefficiencies and manual processes

BACS requires a correctly formatted payment file submitted within a specific daily window. A single formatting error can push the entire payroll run back by a working day.

Faster Payments doesn't solve this at scale either. Sending hundreds of individual payments manually takes time, introduces more room for error, and isn't a realistic substitute for a batch file when you're paying a large team.

Scalability challenges for growing teams

As headcount grows, payroll complexity increases. More employees means more bank details to manage, more opportunities for data errors, and if you're hiring internationally, more currencies to navigate outside either system's scope.

UK businesses often handle international salary payments through their high-street bank as a workaround, which typically means opaque FX costs and no clear visibility on when the money lands. That's where the admin burden grows quietly but consistently.

Lack of international payment support

BACS and Faster Payments are UK-only systems that process GBP between UK bank accounts. That's fine for domestic payroll, but it leaves international employees and contractors entirely outside the picture. A separate cross-border payment solution is a requirement, not a nice-to-have.

Wise Business fills that gap. It handles international salary payments in 40+ currencies, connects to Xero, QuickBooks, FreeAgent, and Sage for automated reconciliation, and works alongside your existing BACS setup without changing how you run domestic payroll.

How Wise Business supports faster and scalable payroll payments

Wise Business handles the international payroll layer that BACS and Faster Payments can't reach. It works alongside your existing UK payroll setup and doesn't require any changes to how you run domestic payroll.

Batch payments for payroll efficiency

Wise Business lets you send up to 1,000 transfers at once from a single spreadsheet upload, covering multiple currencies and countries in one pay-in. The batch payments tool is free to use, and recipients get the money directly in their local bank account with no Wise account needed on their end.

Multi-currency accounts for international payroll

Hold 40+ currencies in your Wise Business account and pay out from the relevant balance without converting back to GBP first. That keeps FX costs down for recurring payroll corridors and gives finance teams a cleaner view of what international payroll actually costs each month.

To unlock local account details and multi-currency features, you'll need the Advanced plan, available for a one-time fee of £50 (Advanced plan) or for free (Essential plan).

Faster payment execution compared to traditional rails

Wise Business sends international payroll at the real exchange rate, with no markup added on top. Every fee shows before you confirm, so there are no surprises when the pay run goes out.

FAQs

Can Faster Payments be used to pay salaries?

Yes. Faster Payments works well for off-cycle salary payments, emergency advances, and corrections to a BACS run. For regular bulk payroll across a large team, BACS is more cost-effective since Faster Payments costs more per transaction, particularly through corporate banking systems.

Does BACS work on bank holidays?

No. BACS only processes banking working days, Monday to Friday, excluding UK bank holidays. A payment submitted on the last working day before a bank holiday won't be cleared until at least three working days after the holiday. Check the BACS processing calendar at the start of each year and adjust submission dates to avoid delays around bank holidays.

How can businesses speed up payroll processing?

The biggest gains come from submitting BACS files earlier than required, which gives you a buffer against missed cutoffs and reduces overall payroll processing time. Forinternational payroll, using a dedicated cross-border platform removes the delays and unpredictable FX costs of routing overseas salary payments through a high-street bank.
