This East Yorkshire-based tech e-tailer's calendar 2020 results were lit up by lockdown, with revenues swelling by over a quarter to £243.5m and net profits skyrocketing from £531,000 to £7.5m. Part of £900m-revenue West Retail Group, eBuyer saw an "immediate and sustained increase in demand" from both businesses and consumers as home working and home schooling became the norm.

Just like all the other e-tailers in this report, eBuyer saw sales mushroom during lockdown. Its profits boomed at an even faster rate as order volumes outgrew costs, prompting it to pay a £9.5m dividend during the year.
