According to the House of Commons Library (
pdf-link), which itself concedes that there is no completely accurate way to make the calculation, between 1993 and 2014 Parliament passed 945 Acts of which 231 implemented EU obligations of some sort.
It also passed 33,160 Statutory Instruments, 4,283 of which implemented EU obligations.
That makes 13% - but if you count all EU regulations, EU-related Acts of Parliament, and EU-related Statutory Instruments, about 62% of laws introduced between 1993 and 2014 apply in the UK., including such like tobacco and olive oil production and many more that actually doesn't affect the UK.
Included in the number of those "laws" are detailed technical administrative decisions, such as updating the scientific registers of chemicals and food additives, and extending the protection period for measures to combat diarrhoea in pigs.
The impact of EU law varies from sector to sector. In many areas - public order, crime, defence, health - EU laws have minimal or no impact.
