How does Omnium make money?

Commission on the energy contracts we place, shown on the rate, line by line. It is not a separate invoice and it is not hidden in the standing charge. You see it before you sign.

What does the initial review cost?

Nothing. We look at your invoices and contract position and tell you what we find. The efficiency reviews that follow are quoted in writing before we start.

What is a Letter of Authority?

A document authorising us to speak to suppliers on your behalf. We hold Level 1 only, which lets us gather your data and approach the market. It does not let us sign anything. You sign every contract yourself.

What happens when my contract ends and I have not signed a new one?

The supply continues on out of contract rates. Those are significantly higher than a contracted price and they are variable, tracking the short term market rather than a rate you agreed. They apply from the day the contract ended.

Why did my bill go up in April?

Regulated network charges and several policy levies reset annually on 1 April. From April 2026 the transmission residual rose by a volume-weighted average of 64 per cent, with individual capacity bands ranging from 28 to 116 per cent. These are set through regulation, not by your supplier.

Will you tell me if I do not need anything?

Yes. Sometimes the answer is to do nothing, and we would rather say so than sell you something.

Where others do not look

A business energy bill is several charges, not one price.

A supplier quote sets the energy price. Network charges, capacity, levies and taxes sit alongside it, and we check each one against your contract.

Wholesale energy

The price of the electricity or gas itself, set when the contract is bought. This is the part a supplier quote competes on.
