This is a live topic again in Whitehall as many departments make heavy weather of sorting out the huge mass of EU laws.
I would start with the complex Emissions Trading scheme. Let’s suspend it as energy prices are so high. The UK version produces the highest carbon taxes making UK industry less competitive. Far from cutting CO 2 the scheme drives the closure of UK business and makes us dependent on more imports. That adds transport CO 2 to fossil fuel intensive output from the exporting country.
Move on to taking VAT off domestic energy and make its removal from green products permanent. Put up the VAT threshold to £250,000 from the EU £85,000 ceiling to allow more small businesses to expand .Amend the fishing regulations to boost the domestic industry and expand the home fleet.
Change the myriad product specification rules. Keep a strong safety requirement but remove the detail about how you can and cannot make individual items. The ban on various hoovers showed this regulation up as unhelpful to UK business.
I have many more proposals but would be interested to hear yours.
