UK-Specific Tips

Time difference: UK is 5 hours ahead of EST (GMT/BST). Business hours in London (9 AM-5 PM) = 4 AM-12 PM EST.

BST adjustment: UK clocks change on different dates than US — there are 2-3 weeks per year where the difference is 4 hours instead of 5.

0800 numbers: UK toll-free numbers (0800, 0808) generally cannot be dialled from the US. Call the regular number instead.

Premium numbers: Numbers starting with 09 are premium rate — avoid calling these from abroad.

Summary

The UK is one of the cheapest countries to call from the US via VoIP — just $0.01/min for landlines. Drop the leading 0, dial +44, and you are connected. BubblyPhone or Google Voice are the best options for most people.
