Calling from United Kingdom

From United Kingdom (GMT (UTC+0) / BST (UTC+1, last Sunday of March to last Sunday of October).) the local business window is 9:00–17:30 typical. Pub-and-lunch culture clusters meetings 10:00–12:30 and 14:00–16:30.. Most outbound callers reach a live answer most easily mid-morning local time, before lunch, and again in the late afternoon.

  • International calls to UK landlines should drop the leading 0 after +44; mobiles likewise (e.g. UK mobile 07700 900000 dials as +44 7700 900000).
  • 070 numbers look like UK mobiles but are 'personal numbers' that can cost the caller £0.50/minute or more — they're not real mobile lines.
