Heli Cloud base

Is your cloud base based AGL or AMSL?
Your cloud base is often very different to reality and very different to the Met Office cloud base map. For example London area on Saturday 23rd at 18:00 TAF is showing 400 feet and your map is showing greater than 1500 feet.

I’m not an aviation specialist, but in this description, for me, it would better to use « height above ground » rather than «altitude above ground ».
Altitude is usually considered above sea level? Or am I wrong?
