What Other Factors Should I Consider?

Whether it’s a business or personal call, there are several considerations that you should consider when calling England or other countries in the UK.

Time Difference

One of the most important items to keep in mind when you’re calling to the UK is the time difference.
The United Kingdom runs on a single time zone UTC+1, or one hour ahead of Universal Time Coordinated (UTC). Compare this to the six different time zones across the continental United States including Alaska and Hawaii:

  • Eastern Time (EDT): UTC-4
  • Central Time (CDT): UTC-5
  • Mountain Time (MDT): UTC-6
  • Pacific Time (PDT): UTC-7
  • Alaska Time (AKDT): UTC-8
  • Hawaii Time (HST): UTC-10

These times are based on Daylight Saving Time (DST).DST happens between late March and late October. All other times,the time in the United Kingdom is UTC.
To understand these differences, look at this example of what they mean. For instance, when it’s 2:00 pm in California, it would be 10:00 pm in London.

Note: Make sure to double-check these time differences before you place a call, as Daylight Saving Time in the US may affect them. Check out this free tool to compare timezones.
As you can see, the time differences between the United States and the UK are significant. It’s important to consult with whomever you’re trying to call to make sure that the agreed-upon time is convenient for both parties. For business calls, earlier is often better, as the end of the workday in the UK is the beginning of working hours in the United States. As long as both parties are in agreement, you can call internationally at any hour of the day.

How Much Do Calls to the UK Cost?

Perhaps the most relevant consideration for anyone making international calls is the cost of doing so. International phone calls can be notoriously expensive and are often cost-prohibitive for people who would otherwise make them on a regular basis. There are several ways to reduce your rates when calling internationally, the most effective of which will be covered in the following section.
