How to Call BT From Abroad
8/27/2026
Quick answer: Call BT's dedicated overseas number at +44 150 174 7714, Monday to Friday 8am to 9pm, weekends and bank holidays 8am to 8pm.
Why BT publishes a separate overseas number
BT's everyday customer service line, 0800 800 150, is a freephone number, and like all UK 0800 numbers, it only routes within the UK's own phone networks. Once you're abroad, it simply won't connect. BT accounts for this on its own site with a dedicated "contact from abroad" page and number, rather than expecting you to guess a reformatted version of the freephone line.

What to have ready before you call
- Your BT account number, found on a recent bill
- The phone number or address registered on your account
- Details of the specific issue: billing, broadband fault, or account changes
Best time to call
The line runs Monday to Friday 8am to 9pm, and weekends and bank holidays 8am to 8pm, wider hours than most UK telecom lines.
- Spain/Western Europe: 1 hour ahead of the UK.
- US East Coast: 5 hours behind the UK, so call in your morning to catch UK hours.
- UAE/Gulf: 3 to 4 hours ahead of the UK.
- Australia (Sydney): 9 to 11 hours ahead of the UK, depending on daylight saving.
The cheaper way to actually make the call
If you're calling about a broadband fault or a billing dispute, expect some hold time, and roaming rates apply for the whole call since this isn't a toll-free number. With DialVia, you call BT's real overseas number over Wi-Fi from your browser instead:
