Your time settings are wrong. I'm also in the UK and have just checked mine. Your current hub time is showing as UTC as are your sunrise and sunset times. They should be followed with 'GMT +1' not 'UTC'. Also your timezone is showing as GMT, it should be 'Europe/London'
In the timezone box, go further down and select 'Europe/London' otherwise it will always follow GMT even when it's BST. (I made the same mistake when I set up my Hubitat a couple of years ago)
