It just invented democracy and the common law. It also gave us most of the practical science and engineering that has given us the industrial revolution.

Democracy was invented in Athens, c 600 BC, not in England.
Common Law is English yes - it arose as a way of merging the Saxon laws with the Norman laws. Note - Scotland is not purely common law - it has it’s own law, “Scots law” which is a blend of common law and civil law
And yes, it gave us the practical science and engineering setting the stage for the industrial revolution.
