I once went with an IMC pilot on a 120 mile trip across the country, we got into cloud. After 10 minutes we had had enough and decided to call it a day, and to land at the nearest airstrip that was still in VMC.
If the cloud is Few at 2000ft that is about as good as it gets in UK, you can always zig-zag to your destination. You can even climb above to 6000 ft and go in a straight line, with minimal turbulence, as long as you can still see some ground beneath you.
However if cloud is above 3500 ft, the tops might be up to 8000ft or more.
