A bank transfer from the USA to the UK moves dollars from your US account into pounds in a UK account, either through your bank’s international wire service on the SWIFT network or through a licensed digital transfer service like Wise, Remitly, or OFX. A single transfer can cost under $10 on a digital platform or $25 to $65 through a traditional US bank, and the exchange rate markup your provider adds on top of the flat fee often costs more than the fee itself. Federal law requires the provider to show you the exact pound amount your recipient will receive before you pay, and you get at least 30 minutes after submitting to cancel for a full refund.
What You Need From the Recipient
Two pieces of routing information are non-negotiable: the recipient’s IBAN and the bank’s BIC.
A UK IBAN is a 22-character code that starts with GB, followed by two check digits, a four-letter bank code, a six-digit sort code, and the eight-digit account number. The format looks like GB29 LOYD 1234 5612 3456 78.1Pay.UK. Standard Format of the IBAN Issued in the UK Your recipient can pull it from a bank statement or their online banking portal.
The BIC (Business Identifier Code) identifies the bank itself. It runs eight characters, sometimes extended to eleven with a branch identifier.2Swift. Business Identifier Code (BIC) You may see it labeled SWIFT code, BIC code, or SWIFT/BIC. Same thing.
Some platforms also ask for a six-digit sort code, but the sort code is already embedded in the IBAN, so the IBAN alone is enough when that’s all the form requests. You’ll need the recipient’s full legal name exactly as it appears on their bank account. A mismatch is one of the most common reasons transfers get held up.
What It Actually Costs
The cost of sending money to the UK comes in three layers: the flat transfer fee, the exchange rate markup, and any intermediary bank charges. Most people focus on the fee and ignore the other two, which is where providers earn most of their money.
Flat Fees
Major US banks charge between $25 and $65 for an outgoing international wire. Sending online is usually cheaper than initiating the wire in a branch or over the phone. Digital transfer services often charge under $10 for the same transfer because they don’t relay funds through the traditional banking chain.
Exchange Rate Markup
The mid-market exchange rate is what banks use when trading currencies with each other. Your provider adds a margin on top of that rate before converting your dollars to pounds. Traditional banks mark up more aggressively than digital platforms. On a $5,000 transfer, a 2% markup costs $100 on top of the flat fee. Comparing the rate your provider quotes to the mid-market rate on any financial news site tells you the real cost of the conversion.
Who Pays the Intermediary Fees
When you initiate a bank wire, you’ll see a field asking who covers the fees. The three standard options work like this:
- OUR: you pay all fees, including intermediary charges, and your recipient gets the full amount.
- SHA (shared): you pay your own bank’s fee; any intermediary bank fees come out of the transfer, so your recipient receives slightly less than the quoted amount.
- BEN: all fees are deducted from the transfer, and your recipient absorbs everything.
SHA is the default at most banks. If a specific pound figure needs to arrive intact, pick OUR and budget for a higher total cost on your end.
Traditional SWIFT wires often pass through one or more intermediary banks between the sending and receiving banks. Each intermediary can deduct a handling fee, typically $10 to $30, and you won’t always know in advance whether one will be involved. That uncertainty is why SHA can leave your recipient short.
Bank Wire or Digital Transfer Service
A traditional bank wire runs on the SWIFT network, a messaging system that coordinates the instructions between your bank, any intermediary banks, and the UK destination bank. It’s the standard for high-value transfers and has decades of infrastructure behind it. The multi-bank relay is what makes it expensive and slow.
Digital transfer services take a different approach. They hold reserves in both countries. You pay in dollars from your US account, and the provider pays your recipient from its own UK-based pound reserves. The intermediary chain disappears, which is why these services are cheaper and faster. They’re regulated as money services businesses under the Bank Secrecy Act and must meet federal anti-money-laundering requirements.3Financial Crimes Enforcement Network.

How Long Delivery Takes
A SWIFT bank wire from the US to the UK typically takes one to five business days. Settlement, compliance screening, and internal processing at each bank in the chain drive the timing. A transfer initiated on Friday afternoon won’t begin processing until Monday, and US or UK bank holidays extend the timeline further.
Digital platforms are significantly faster. Some deliver within minutes, and the majority arrive within 24 hours. Once the provider credits pounds to the recipient’s UK account, the UK’s Faster Payment System can process the final deposit in near real-time, since it operates around the clock, every day of the year.4Pay.UK. Faster Payment System
Compliance holds and data errors cause most delays. If a bank’s automated screening flags your transfer, it sits in a queue until someone reviews it. Providing the recipient’s full legal name, complete address, and a clear purpose of payment reduces the odds of a flag.
Your Disclosure and 30-Minute Cancellation Right
Federal law gives you concrete protections when sending an international remittance. Under 15 U.S.C. ยง 1693o-1, every remittance transfer provider must give you a written disclosure before you pay, showing the exchange rate, the dollar amount being transferred, all fees and taxes the provider collects, and the total amount in pounds your recipient will receive.5Office of the Law Revision Counsel. 15 USC 1693o-1 – Remittance Transfers The implementing regulation also requires providers to warn you if a third-party bank might deduct additional fees that would reduce the final amount.6eCFR. 12 CFR Part 1005 Subpart B – Requirements for Remittance Transfers
Read that disclosure before confirming. If the exchange rate or fees look different from what you expected, this is your last free exit.
After you submit payment, you have at least 30 minutes to cancel for a full refund, provided the funds haven’t already been deposited into the recipient’s account.7eCFR. 12 CFR 1005.34 – Procedures for Cancellation and Refund of Remittance Transfers On a bank wire that takes days to settle, this window is easy to catch. With instant digital transfers, the money may reach the recipient before those 30 minutes elapse, which effectively closes the cancellation window. If speed matters less than keeping the option to cancel, choose a slower delivery method.
Reporting Thresholds That Affect Your Transfer
There is no legal cap on how much you can send to the UK in a single transfer, but several reporting thresholds apply. Your bank handles most of this behind the scenes.
For any transfer of $3,000 or more, your bank must collect and transmit information along with the payment, including your name, address, and account number. This is the Travel Rule, and it exists so identifying information follows the money through the banking chain.8FFIEC. Funds Transfers Recordkeeping – Overview
When a transaction involves more than $10,000 in cash, your bank must file a Currency Transaction Report with FinCEN, regardless of the purpose.9FinCEN. Notice to Customers – A CTR Reference Guide Splitting a large transfer into smaller pieces to stay under this threshold is called structuring, and it’s a federal crime even if the underlying money is legitimate.
Banks also file Suspicious Activity Reports for transactions of $5,000 or more that appear unusual, have no obvious lawful purpose, or look designed to evade reporting requirements.10eCFR. 12 CFR 208.62 – Suspicious Activity Reports You won’t be notified if a SAR is filed on your transaction. The practical response: keep documentation of why you’re sending money, especially for large or repeated transfers.
Every US bank also screens international transfers against the Treasury Department’s sanctions lists. If the recipient, their bank, or any intermediary matches a name on the Specially Designated Nationals list, the bank must block the transfer. A flag doesn’t mean you’ve done anything wrong, but your funds will freeze until the bank finishes its review.11U.S. Department of the Treasury. OFAC Sanctions Compliance FAQs
Tax and Foreign Account Reporting
Sending money overseas doesn’t create a tax liability by itself, but several reporting requirements can apply depending on your circumstances.
FBAR
If you own or have signature authority over a UK bank account and the combined value of all your foreign accounts exceeds $10,000 at any point during the year, you must file FinCEN Form 114, the FBAR. It’s due April 15 with an automatic extension to October 15.12Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) The $10,000 threshold is aggregate across all foreign accounts, not per account. Penalties for failing to file can be severe even for non-willful violations.
Form 8938 (FATCA)
Separately from the FBAR, the IRS requires Form 8938 if your foreign financial assets exceed certain thresholds. For a single taxpayer living in the US, the trigger is $50,000 on the last day of the tax year or $75,000 at any point during the year. For married couples filing jointly, those thresholds double to $100,000 and $150,000.13Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets FBAR and Form 8938 overlap but go to different agencies on separate forms.
Gifts
If you’re sending money to a UK resident as a gift rather than a payment for goods or services, the annual gift tax exclusion for 2026 is $19,000 per recipient.14Internal Revenue Service. What’s New – Estate and Gift Tax You can give up to that amount to any number of people without filing a gift tax return. Above $19,000 to a single recipient, file IRS Form 709, though you likely won’t owe tax until your cumulative lifetime gifts exceed the lifetime exemption. On the receiving end, if a foreign person sends you more than $100,000 in a year, you must report it on Form 3520.15Internal Revenue Service. Instructions for Form 3520 – Annual Return to Report Transactions With Foreign Trusts and Receipt of Certain Foreign Gifts
If Something Goes Wrong
For remittance transfers, you can file a notice of error with your provider within 180 days of the promised delivery date. The provider must investigate and either correct the error or explain why no error occurred.16eCFR. 12 CFR 1005.33 – Procedures for Resolving Errors Covered errors include the wrong amount arriving, undisclosed fees, and funds never reaching the recipient.
If money goes to the wrong account because you entered incorrect details, recovery is harder. Your bank can send a recall request through the SWIFT network, but the receiving bank isn’t obligated to return the funds if the account holder refuses or has already withdrawn them. Initiating the recall within 24 to 48 hours gives you the best shot. For unauthorized transfers, where someone accessed your account without permission, standard electronic fund transfer protections apply and your bank bears the liability once you report the problem.
Save the confirmation number your provider issues when you submit a transfer. If anything goes wrong downstream, that number is the starting point for every inquiry and dispute.
