USD to GBP for business payments
To pay a supplier in the United Kingdom, convert US dollars to pounds sterling (GBP) and pay its sort code and account number, by Faster Payments or CHAPS from a sterling account or by SWIFT from a dollar account. The cost is the margin over the mid-market rate plus the payment fee. This page is for businesses outside Europe paying UK suppliers: how sterling's rate works, the payment systems, the details to collect, the costs and when dollars fit better.
- The Bank of England states that the daily spot rates it publishes are not official rates and are no more authoritative than those of any commercial bank in the London foreign exchange market.
- Faster Payments operates 24 hours a day, seven days a week, with a maximum of £1,000,000 per transaction; most payments arrive instantly but some can take up to two hours.
- The Bank of England operates the UK's RTGS infrastructure until 6pm on business days, and customer CHAPS payments end at 5:40pm, although banks may set earlier deadlines.
- Pay.UK introduced Confirmation of Payee in 2020, an account name check that helps prevent UK domestic payments going to the wrong account.
- Helm gives eligible companies outside the UK and the European Economic Area GBP account details with a sort code for Faster Payments and SWIFT, with pricing agreed in writing before the account opens.
Sterling and how its rate is set
The pound sterling (code GBP) is the currency of the United Kingdom, and the Bank of England is the UK's central bank and issues banknotes; its banknotes pages note that six banks in Scotland and Northern Ireland also issue banknotes. There is no official dollar rate for sterling. The Bank of England publishes daily spot rates against sterling, but its exchange rates page states that they are not official rates and are no more authoritative than that of any commercial bank operating in the London foreign exchange market.
In practice, the rate you get is set entirely by the bank or provider that converts your dollars. The Bank of England's daily spot rates, like any mid-market rate, are useful for checking a quote, not for dealing.

Faster Payments, CHAPS and SWIFT
Faster Payments is the UK's instant payment system, built on infrastructure provided by Pay.UK. Griffin reports that 45 companies participate directly, that it operates 24 hours a day, seven days a week, and that the maximum per transaction is £1,000,000. Transfers between participating banks typically happen instantly, but some can take up to two hours. CHAPS is the same-day system for high value payments: the Bank of England operates the RTGS infrastructure until 6pm on business days, with customer CHAPS payments ending at 5:40pm.
| Route | Best for | Timing | Points to check |

| Faster Payments from a sterling account | Most supplier invoices | 24/7; usually instant, up to two hours | Up to £1,000,000 per transaction; banks may set lower limits |

Details you need to pay a UK supplier
A UK account is identified by a sort code and an account number, which UK buyers and suppliers use for Faster Payments and CHAPS. Pay.UK's Confirmation of Payee checks the account name against the details before a domestic payment is sent; a mismatch warning is your cue to call the supplier on a number you already hold. Treat any email asking you to change a UK supplier's sort code or account number the same way, and confirm it by phone before the next payment.
| Detail | What to collect | Why it matters |
|---|---|---|
| Beneficiary name | The supplier's legal name, as on its bank account | Checked by Confirmation of Payee |
| Sort code and account number | From the supplier's invoice or letterhead | Used for Faster Payments and CHAPS |
| IBAN and BIC | If you will pay by SWIFT from a dollar account | Used to route an international wire |
| Company number or VAT number | From the supplier's invoice | Links the bank details to the invoicing company |
| Reference | Invoice number | Lets the supplier match the payment |

What converting USD to GBP costs
The cost is the mid-market rate, the margin your bank or provider adds and the payment fee. Chase charges $5 for an online foreign currency wire, or $0 at $5,000 or more; the margin in its rate is not shown in the fee table. On a sterling wire, ask for the rate and the pounds the supplier will receive before you approve it, then compare that rate with the mid-market rate at the same moment.
Our currency converter shows reference rates for a quick check. On a $50,000 payment, each 0.10% of margin costs $50.
Helm agrees pricing with each business in writing before the account opens, and shows the rate, the fee and the expected arrival before you confirm each payment. See how Helm pricing works.
