UK sector benchmarks
Electricity, gas, steam and air conditioning supply: what the filed accounts say
Cash, creditors falling due within one year, current ratio, net assets and headcount for UK electricity, gas and steam supply companies, split by size, from accounts filed at Companies House. Covering generation, transmission and distribution of electricity, gas and heat.
Half of UK electricity, gas and steam supply companies hold less than £1.25 of current assets for every pound falling due within the year, measured across 914 filed sets of accounts.
Figures as at 2026-Q4, the fourth quarter of 2026. Every row states the number of companies it is drawn from. Groups of fewer than 50 companies are suppressed and said to be suppressed. How these figures were made.

The figures
Quartiles by size band
A median is the middle company: half of this sector sits below it. The quartiles are the companies a quarter and three quarters of the way up. Sample sizes differ from row to row because each figure is counted only where a filing states it.
All sizes
every company in the sector, including those whose filing states no headcount

the largest band this dataset separates
No figure for this size band clears the 50-company floor, so the whole band is suppressed.
What is not here
There is no trading figure on this page, and there cannot be
A small company files abridged accounts, which carry a balance sheet and no trading account. So nothing on this page says what these companies take in or what they keep, and no amount of sample size would change that. Anyone quoting a sector trading figure from this source is quoting something the source does not hold.
There is no figure here for all UK companies either. A middle value taken across incomparable sectors is a number about nothing, and it is exactly the unsourced rule of thumb these pages exist to replace.
Of the 25 figures this sector could report, 18 clear the floor and 7 are suppressed for want of companies.
