Here in the UK, just after 7pm will be the peak

Depending on where you are in the UK, the eclipse will be at its maximum between 19:02 BST and 19:16 BST. What time the peak occurs for you will depend mostly on how far north you are. In general, the further north, the earlier you will see the maximum eclipse. And, in general, the further west you are, more of the Sun will be covered. The best places to view the eclipse are from higher ground, or areas with a clear view towards the western horizon.
