Sheets
- 01Bills and charges
Network charges and agreed capacity
Why regulated network charges rose sharply in April 2026, and why the capacity you reserve is a lever most businesses have never pulled.
Verified PDF - 02Bills and charges
Non-commodity charges
Taxes, levies and regulated network charges now make up a large share of a business electricity bill, and comparing unit rates alone misses where the cost sits.
Verified PDF - 03Bills and charges
The April reset, and the grid investment behind it
What resets on a business energy bill each April, why network charges are rising, and why this is regulated investment rather than a supplier price rise.
Verified PDF - 05Bills and charges
Power factor and reactive charges
A poor power factor means a site draws more current than the work requires, and pays for it through reactive charges and inflated capacity.
Verified PDF - 06Bills and charges
Transmission charges, TNUoS
What TNUoS pays for, why it moves every April, and the one question worth asking a supplier before you sign.
Verified - 17Bills and charges
Reading your energy bill
What every line on a commercial gas and electricity bill means, so you can check it is right and see which parts you can influence.
Verified PDF - 28Bills and charges
The British Industrial Competitiveness Scheme and industrial electricity costs
A proposed cut to industrial electricity costs by removing policy charges, who would qualify, and why eligibility is tested at sector level.
Verified - 30Bills and charges
Invoice validation
What goes wrong on energy invoices, how validation works against the contract, and why we validate for payment rather than approve.
Verified PDF - 33Bills and charges
What an invoice audit finds, and what it cannot
What an audit of business energy invoices actually tests, the evidence each test needs, and the honest limits of what it can recover.
Verified - 34Bills and charges
Recovering an overcharge from a supplier
How a billing query is raised with an energy or water supplier, the evidence it needs, how far back a claim can reach, and what a recovery looks like.
Verified - 36Bills and charges
Controlling utility cost across several sites
How to hold an estate as one record, compare sites fairly, and find the losses that only appear when a business runs more than one site.
Verified - 41Bills and charges
What really drives your electricity bill
Wholesale power is a minority of a typical business electricity bill. Every layer that drives the total, and what can and cannot be done about each.
Verified - 42Bills and charges
The small lines on your bill
AAHEDC, Elexon and BSC costs, RCRC and metering agents: what each line is, who sets it, and why only one of the four is genuinely negotiable.
Verified PDF
The standard
Every sheet, held to the same rules.
Sourced, not asserted
Where a figure is set by government or by a regulator, the sheet names the instrument it comes from.
Proposed is labelled
Where something is proposed rather than law, the sheet says so, so a decision is not taken on a consultation.
Board-pack PDF
Every sheet can be taken away with a cover page, a running head and the verification date on every page.
