How to Make Free Calls to the UK in 2026

The United Kingdom is one of the most-called international destinations in the world. Whether you have family in London, business contacts in Manchester, or friends studying in Edinburgh, chances are you need to call a UK number at some point.

Calls to the UK are among the cheapest international calls available — VoIP rates are just a few cents per minute. But can you call the UK for free? That depends on what you mean by "free" and what kind of number you are calling.

UK Phone Number Formats

Before diving into calling options, understanding UK number formats will save you frustration. The UK uses a variety of number types, and the format tells you what kind of number it is.

Country code: +44

Dialing from abroad: Drop the leading 0 from the UK number, then add +44.

Number TypeUK FormatInternational FormatNotes
London landline020 7946 0958+44 20 7946 0958Starts with 020

Toll-free0800 123 4567+44 800 123 4567Free within UK
Premium rate09XXAvoid calling these internationally

The critical detail: UK mobile numbers always start with 07 (or +44 7 in international format). Landline numbers start with 01 or 02 followed by an area code. This distinction matters because the cost of calling a mobile is different from calling a landline.

Pro tip: UK numbers starting with 03 are non-geographic numbers charged at the same rate as landlines. If you see an 03 number for a UK business, it will cost the same as calling their landline.

Free Ways to Call the UK

App-to-App Calling

The only truly free and universally available way to call someone in the UK is through a messaging app that both of you use. WhatsApp is enormously popular in the UK — most people under 60 have it on their phone.

FaceTime works if both of you are Apple users. Signal, Telegram, and Facebook Messenger are other options.

The limitation is always the same: both parties need the app and internet access. You cannot reach a UK landline this way, and you cannot call someone who does not use the app.

Google Voice (US to UK: Not Free)

Unlike calls to Canada, Google Voice does not offer free calls to the UK. Calls to UK numbers from Google Voice require prepaid credits and are charged per minute. The rates are low but not zero.

Free Trial Minutes

Some VoIP services offer a small number of free minutes when you sign up. These can be enough to test a service but are not a long-term solution. A few minutes of free calling to the UK is useful for verifying that the quality meets your needs before committing to purchasing credits.

Cheap Ways to Call the UK

UK calling rates through VoIP services are among the lowest for any international destination. The country has mature telecom infrastructure and competitive termination rates, which translates to low per-minute costs.

Mobile vs. Landline: Why the Price Differs

This is the single most important cost factor when calling the UK. Calling a UK landline is significantly cheaper than calling a UK mobile:

DestinationTypical VoIP RateWhy
UK landline (01, 02, 03)$0.01–$0.02/minLow termination fees from BT and other landline carriers
UK mobile (07)$0.03–$0.08/minHigher termination fees from mobile carriers (Vodafone, EE, Three, O2)

The difference can be three to four times. If you regularly call a UK mobile for extended conversations, this adds up. However, even UK mobile rates through VoIP are far cheaper than carrier international rates, which can be $0.50 to $2.00 per minute.

Browser-Based VoIP

MinuteWise lets you call UK landlines and mobiles from any browser. No app to download, no subscription needed. You buy credits and pay per minute, with rates among the lowest available for UK destinations.

This is particularly useful if you need to call UK numbers from various devices — your work computer, a hotel lobby computer, your tablet. Log in from any browser and call.

VoIP Apps

Skype offers calls to UK numbers starting at competitive per-minute rates with Skype Credit, or you can purchase an unlimited calling plan for the UK. Viber Out offers similar rates. Both require downloading their respective apps.

Carrier International Plans

If you have a mobile plan that includes international minutes, check whether the UK is covered. Many carriers include the UK in their international calling add-ons, typically for $5 to $15 per month. This makes sense if you call UK numbers daily, but overpaying for a monthly plan you underuse is common.

Calling UK Businesses

Calling UK businesses from abroad involves a few specific considerations:

Business hours: The UK operates on Greenwich Mean Time (GMT/UTC+0) in winter and British Summer Time (BST/UTC+1) from the last Sunday of March to the last Sunday of October. Standard business hours are 9:00 to 17:30.

0800 and 0808 numbers: These are freephone numbers within the UK, but VoIP services may charge standard per-minute rates when calling them from abroad. Check your provider's policy on UK toll-free numbers.

0845 and 0870 numbers: These are service numbers that cost more than standard calls within the UK. Many businesses have moved away from these in recent years, but some still use them. Look for an alternative geographic number (starting with 01 or 02) on the company's website — it is almost always cheaper to call.

Automated phone menus: UK businesses commonly use interactive voice response (IVR) systems. Have any reference numbers ready before calling to avoid spending minutes navigating menus.

Pro tip: Many UK businesses list a geographic number alongside their service numbers on their "Contact Us" page. The geographic number (01 or 02) is cheaper to call internationally and often connects to the same department.

Time Zone Considerations

The UK's time zone makes it relatively easy to call from many parts of the world during business hours:

Calling FromTime DifferenceBest Calling Window
US East CoastUK is +5 hoursMorning your time (afternoon UK)
US West CoastUK is +8 hoursEarly morning your time
Central EuropeUK is -1 hourMost of the day works
IndiaUK is -5:30 hoursAfternoon your time (morning UK)
Australia (Sydney)UK is -10/11 hoursMorning your time (evening UK)
Middle East (Dubai)UK is -4 hoursAfternoon your time (morning UK)

Keep in mind that the UK and your country may switch to and from daylight saving time on different dates, which can shift the time difference by an hour for a few weeks in spring and autumn.

Cost Comparison for a Typical UK Calling Pattern

To put the costs in perspective, here is what a common UK calling pattern might cost across different methods. Assume you make three calls per week to the UK, averaging eight minutes each — roughly 96 minutes per month.

MethodMonthly Cost (est.)Notes
Mobile carrier international plan$10–$15/monthFixed monthly fee regardless of usage
Calling card$3–$8 + connection feesConnection fees add up with 12 calls/month
Skype subscription (UK plan)~$3–$7/monthGood value if you use all minutes
Pay-as-you-go VoIP (landline)~$1–$2/monthNo monthly fee, pay only for what you use
Pay-as-you-go VoIP (mobile)~$3–$8/monthHigher per-minute rate for mobiles
App-to-app (WhatsApp)FreeOnly if recipient uses the app

For occasional callers, pay-as-you-go is the clear winner — you never pay for minutes you do not use. For daily callers to UK mobiles, a subscription plan might save a small amount per minute but requires consistent usage to be worthwhile.
