To call British Gas from abroad, you’ll need to reformat UK contact numbers for international dialing and avoid roaming charges by using a solution like the Mytello app. Whether you’re calling about an energy bill, Pay As You Go top-up, or a gas emergency, Mytello connects you over Wi-Fi or through a local dial-in number. Support numbers such as 0333 202 9802 become +44 333 202 9802 and work globally when dialed correctly.
How to Call British Gas from Outside the UK
Most British Gas support lines begin with 0333, which are not toll-free when dialed internationally. If you use your mobile carrier from abroad, the call will likely be billed at standard international rates, unless you’re using a service like Mytello that reduces this cost dramatically.
Step-by-Step: How to Dial British Gas Internationally
- Identify the number you need (e.g., 0333 202 9802 for general support).
- Drop the leading 0: → 333 202 9802
- Add the UK country code: → +44 333 202 9802
- Dial using this format via Mytello or your phone app.
Example:
If you’re calling British Gas from the USA using Mytello:
+44 333 202 9802, routed via VoIP or local access.
Tip: Save up to 90% compared to international mobile rates by calling through the Mytello app. The app also filters and formats international numbers automatically, no manual dialing needed.
Which British Gas Number Should You Call From Overseas?
British Gas offers different numbers depending on the type of issue. Each must be formatted properly for international calls.
| Purpose | UK Number | International Format | Available Hours |
| General Customer Service | 0333 202 9802 | +44 333 202 9802 | Mon–Fri, 8am–6pm (UK Time) |
| Metering / Prepay Issues | 0330 808 3880 | +44 330 808 3880 | 24/7 |
| Gas Emergency | 0800 111 999 | UK-only (local access only) | 24/7 |
| Electrical Power Emergency | Call 105 | UK-only | 24/7 |
Important: The Gas Emergency number (0800 111 999) and Power Cut line (105) are usually not reachable from outside the UK. If you’re abroad and facing a time-sensitive issue, contact +44 330 808 3880 first. The Mytello app connects you through a local access number, even in emergency scenarios, and works without activating roaming.
How to Dial a UK Number from Abroad (Format + Country Code)
When calling British Gas from outside the UK, you need to convert their number into an international dialing format. This applies whether you’re in the USA, UAE, India, Australia, or any other country. The standard process follows three steps:
- Remove the leading 0 from the UK number
- Add the UK country code: +44
- Dial the new number using your phone or through the Mytello app
Examples:
- 0333 202 9802 → +44 333 202 9802
- 0330 808 3880 → +44 330 808 3880
- 0800 111 999 → not typically reachable outside the UK
For convenience, Mytello automatically reformats UK numbers inside the app. Once you install it, your contact list is filtered for international compatibility, and the call is placed either via VoIP (Wi-Fi/data) or via a local dial-in number, no manual formatting or prefixing needed.
For more help with international formats, see our guide on calling UK toll-free and landline numbers from abroad, which follows the same structure used for British Gas and other UK-based services.
Avoiding Roaming Fees When Calling British Gas from Abroad
Calling a UK-based number like 0333 202 9802 through your mobile carrier from abroad will almost always trigger roaming charges, even if your plan includes “free EU roaming.” That’s because 0333 numbers are not considered toll-free from outside the UK, and they often fall into premium international brackets on global SIMs or eSIM providers.
Here’s where the Mytello app (iOS or Android) comes in:
- VoIP first: Connects over Wi-Fi or data by default
- Fallback mode: Switches to local dial-in if your signal is weak
- No SIM change: Works on any mobile, even SIM-free
- Live tracking: See call costs and time inside the app
- Global coverage: Works in 220+ countries
Many users assume services like Skype, FaceTime, or WhatsApp can be used to reach British Gas, but the company does not accept inbound calls through those platforms. They require a standard voice connection to a UK landline or mobile number. Mytello is purpose-built for that: it connects directly to UK numbers without triggering roaming fees or unexpected carrier charges.

Emergency Gas Issues While Abroad What to Do
Emergency Gas Issues While Abroad — What to Do
If you’re managing a UK property and encounter a gas-related emergency while abroad — such as a suspected leak, smell of gas, or carbon monoxide alert — the standard response in the UK is to call the Gas Emergency Services line at 0800 111 999. However, this number typically does not connect from international numbers or non-UK SIMs.
Here’s how to manage this from outside the UK:
- Open the Mytello app and use the dial-in mode to access a local UK routing line. This works even if your SIM has no roaming.
- If you cannot reach the emergency line directly, call British Gas general support at +44 333 202 9802. Explain the situation and your location, their agents can escalate it internally.
- For non-urgent but time-sensitive issues (e.g. appliance faults, prepay meter outages), contact +44 330 808 3880, which is open 24/7 for metering support.
- If phone lines are unavailable, email: customerservices@britishgas.co.uk mention that you are abroad and the issue involves safety.
To learn more about safety protocols, visit the British Gas emergencies page, especially if you’re dealing with shut-off valves, cold weather pipe bursts, or carbon monoxide alerts.
Pro tip: Save all three key numbers in your Mytello app contacts, the app will automatically apply the correct dial format and fallback method based on your current country and connection strength.

Other Ways to Reach British Gas from Overseas

📩 customerservices@britishgas.co.uk

Common Mistakes to Avoid When Dialing from Abroad
Every week, British Gas customers abroad make the same avoidable errors when trying to reach support. Here’s how to steer clear of the most frequent issues:
Dialing with the leading 0
UK numbers like 0333 202 9802 must be formatted as +44 333 202 9802 when called internationally. Leaving the zero results in call failure or misconnection.
Assuming 0333 numbers are free from abroad
0333 numbers are free from some UK mobiles and landlines, but not from overseas networks. Calling without a roaming-inclusive plan often triggers international charges.
Using unsupported apps
British Gas does not accept calls through WhatsApp, FaceTime, Skype, or Facebook Messenger. You need a method that connects to actual phone numbers like the Mytello app, which supports both VoIP and dial-in fallback.
Calling outside business hours
General support lines follow UK business hours (Monday–Friday, 8am–6pm). If you’re calling from North America or Asia, check the time zone before dialing.
Relying only on email for urgent issues
While email is useful for follow-ups, emergencies should always be handled by phone. Use Mytello or another trusted dial-in method to reach a live agent quickly.
