Assuming you are VFR, a PPL, less then 140 kts in an aeroplane, the UK law says you could operate over the sea or a known empty field at a ceiling of less than 100 ft and viz of 3 km. You are VFR (Clear of Cloud and 1.5 km viz), You meet your PPL viz limit (3kms), and you are more than 500 ft from people or structure. What is legal is not necessarily safe and this would certainly fall into the very unsafe camp.
Pulse1's 'greater of 1500 ft or 1000 feet above highest terrain nearby' is a reasonable limit for a flight away from the local area.
