Should the UK be allowed to access European Markets once they leave the EU?

The EU single market removes all regulations and trade barriers amongst the 28 member countries of the European Union. The goal of the single market is to stimulate competition and trade, improve efficiency, raise the quality of goods and reduce prices. After the UK voted to leave the EU in 2016 the issue was raised as to how businesses in the UK would participate in the market. Several member countries proposed charging the UK a fee to participate. Norway currently pays a fee to participate and analysts estimate that charging the UK a similar fee would amount to $4 - $5 billion a year.
