How To Call United Kingdom From Singapore

Quick Reference Summary

To call the United Kingdom from Singapore:

001 + 44 + Area/Mobile Code (without the 0) + Local Number

Examples:

• For London landline: 001 + 44 + 20 + XXXX XXXX
• For UK mobile phone: 001 + 44 + 7XXX + XXXXXX

When it’s 5 PM in Singapore, it’s 9 AM (GMT) / 10 AM (BST) in the UK. (UK is 8 hours behind Singapore during GMT – late Oct to late Mar; 7 hours behind during BST – late Mar to late Oct)

How to Call a Landline in the UK

Calling a UK landline from Singapore is straightforward if you follow these steps:

1. Dial Singapore’s international access code: 001 (or 002, 008 depending on your phone company)
2. Dial the United Kingdom’s country code: 44
3. Dial the UK area code, making sure to drop the leading 0. (e.g., for London ‘020’, just dial ’20’; for Manchester ‘0161’, just dial ‘161’)
4. Dial the local phone number.

For example, if you’re calling a Manchester number written as (0161) 123 4567, you would dial 001 44 161 123 4567 from Singapore.

Important Note: UK phone numbers are often written with a leading ‘0’ before the area code when dialed within the UK. You must omit this ‘0’ when calling internationally from Singapore.

How to Call a Mobile Phone in the UK

Calling a UK mobile phone follows a similar pattern:

1. Dial Singapore’s international access code: 001 (or 002, 008)
2. Dial the UK’s country code: 44
3. Dial the mobile phone prefix, making sure to drop the leading 0. UK mobile numbers almost always start with ’07’ domestically, so internationally you will dial ‘7’ followed by the remaining 9 digits.
4. Dial the rest of the mobile number (usually 9 digits).

For example, if the UK mobile number is 07700 900 123, you would dial 001 44 7700 900 123 from Singapore.

Key Point: Always remove the first ‘0’ from the UK mobile number when dialing from abroad.

Different Ways to Dial Internationally from Singapore

Singapore gives you several options for international access codes depending on which phone company you use:

• 001: SingTel
• 002: M1
• 008: StarHub

The code you choose might affect how much your call costs with your standard provider. If you’re using a phone card like the ones offered by Singapore Phone Cards, make sure to follow the specific access number instructions provided with your card.

Understanding UK Phone Numbers

Landline Numbers

• UK landline numbers typically start with a 0 followed by an area code (which can be 2 to 5 digits long).
• When calling internationally, you MUST drop the leading 0.
• The total length of a UK landline number (including the area code but without the leading 0) is usually 10 digits, but this can vary slightly. London numbers dialed internationally start with 44 20, followed by 8 digits. Most other major cities start with 44 1 or 44 2, followed by 9 digits.

Mobile Numbers

• UK mobile numbers almost universally start with 07 when dialed domestically.
• When calling internationally, you MUST drop the leading 0 and dial 7 after the country code 44.
• The total length of a UK mobile number dialed internationally is 44 7 followed by 9 digits.

Major UK Area Codes (Landlines)

Here are some common area codes for major UK cities. Remember to drop the leading 0 when dialing from Singapore:

UK Mobile Phone Prefixes

As mentioned, UK mobile numbers start with 07 domestically. When dialing from Singapore, you drop the ‘0’ and dial ‘7’ after the ’44’ country code. Common beginnings after +44 7 include:

• +44 71xx +44 72xx +44 73xx +44 74xx +44 75xx
• +44 77xx +44 78xx +44 79xx

These cover all major UK mobile networks like EE, O2, Vodafone, Three, and various MVNOs.

Time Difference

The UK operates on two time zones during the year:

• Greenwich Mean Time (GMT): UTC+0 (Typically late October to late March)
• British Summer Time (BST): UTC+1 (Typically late March to late October)

Singapore is always UTC+8.

• When the UK is on GMT (UTC+0), Singapore is 8 hours ahead. (e.g., 5 PM Singapore = 9 AM UK)
• When the UK is on BST (UTC+1), Singapore is 7 hours ahead. (e.g., 5 PM Singapore = 10 AM UK)

Remember to check if the UK is observing Daylight Saving Time (BST) when planning your call.

Special Numbers to Know

• Emergency: 999 or 112 (Cannot be dialed from outside the UK)
• Toll-Free: Numbers starting with 0800 or 0808. These are usually free from UK landlines/mobiles but may not be reachable from Singapore, or may incur international charges if they are.
• Premium Rate: Numbers starting with 09. These are expensive and generally cannot be called from outside the UK.
• Directory Enquiries: Numbers starting 118 (Cannot be called from outside the UK).

Calling Business Extensions

When calling a UK business that uses extensions:

1. Dial the full international number (001 44 Area Code (no 0) Number).
2. Listen for the automated attendant or receptionist.
3. Enter the extension number when prompted.

Most UK businesses will have English-language automated systems or receptionists.

Best Time to Call

Considering the 7 or 8-hour time difference, the best overlap for business hours (typically 9 AM – 5 PM in the UK) is:

• Singapore Evening (4 PM – 1 AM SGT): This corresponds to roughly 9 AM – 5 PM / 10 AM – 6 PM in the UK (depending on GMT/BST).
• Calling early in the Singapore morning (e.g., 8 AM SGT) will be midnight or 1 AM in the UK, which is usually too early.

Check the time difference carefully before placing your call, especially if calling someone personally.
