Every profit figure here is the one the company filed.
The chart splits each company's turnover into £100: what goes on people, on interest and on everything else, and what is left as profit.
Out of every £100 of turnover
Each column is £100 of that company's own turnover, so companies of any size compare on one scale; the figures are pounds out of each £100, not millions. Companies run from the best margin to the worst. Payroll is staff costs, financing is interest paid, other running costs are everything else, and profit is pre-tax profit, filed or estimated as marked in the table. A loss is not an extra cost: it is the part of the costs that runs past the £100 line, marked with a red bracket. Hover over any segment for its figure.

Turnover change on each company's own prior year
Who employs the most, who pays the most, and who brings in the most per head?
E.ON Next employs the most, 4,020 people, against 3,631 at EDF.
E.ON Next has the highest average staff cost, about £43,000 a head.
E.ON Next brings in the most turnover per employee, about £1.8m. It says as much about the business model as the workforce: a marketplace or a wholesaler needs far fewer people per pound than a restaurant or a gym.
Per-head figures are left out for EDF (staff costs under 2% of turnover): the staff are probably employed by another company in the group, so dividing by this company's headcount would mislead.
