Brexit: can the energy sector learn from financial services?

It seems axiomatic that immediately prior to the UK’s exit from the EU on 29 March 2019, the UK's domestic laws (in England and Wales, Scotland and Northern Ireland) will be aligned with EU law.

Assuming a crash-landing "no deal" scenario can be avoided, any future trading arrangement between the UK and the EU27, will need to provide a framework through which agreed levels of market access can be maintained and post Brexit divergences between UK and EU law and regulation can be managed.
