This research poster analyses the impact of lockdown on UK businesses in three major phases: past, present, and future. It suggests that UK-based companies should adopt changes and apply relevant market strategies to achieve sustainable and ethical growth. The research methodology used secondary data collection and quantitative research methods to interpret the data. The data interpretation includes graphs and tables that show the impact of lockdown on UK businesses. The poster concludes that to increase the turnover of the companies, it is important to boost in the near future when people start recovering from their own phases.
