Bill audit

Not the electricity

Network, capacity and levy charges are often more than the energy itself. Almost nobody checks them, and there is a reason.

Why nobody looks

Brokers are paid on the supply contract, which is the commodity half. The half where the errors live earns them nothing.

We are not above that. Installers pay us for introductions, and procurement partners pay us where a contract is placed. The audit gives us accurate data, which is what makes the modelling worth anything.

What we check

Four errors, all of them fixable without spending capital.

Capacity

Agreed capacity

Half hourly sites pay for reserved capacity whether or not it is used. Paying for 500 kVA and never going above 214 is money going nowhere every month, and the meter shows that on day one.

Network

Classification

Distribution charges depend on how the connection is classified. The wrong profile is paid for quietly, for years.

Levies

Climate Change Levy

Reliefs and exemptions exist for certain uses. Where a site qualifies and the supplier was never told, the levy is paid without cause.

Tax

VAT rate

Some qualifying use is charged at the reduced rate. The wrong rate persists across every bill until somebody looks.

Reducing agreed capacity is a request to the network operator, not a purchase. It needs care, because coming back up is not always quick and measures like EV charging need the headroom.

What a finding looks like

Worded plainly, with the line it was read from and the amount attached.

Across 1 finding. The rest carry no figure because the bill did not show enough.

  • Unused agreed capacity
    £4,120

    Your agreed capacity is 500 kVA and your measured peak over the last twelve months is 214 kVA. That is worth checking with your network operator, because you pay for the capacity whether you use it or not.

  • VAT rate
    No figure

    The office supply is charged at the standard rate of VAT. Where a site is largely low use or qualifying, a reduced rate can apply and a declaration corrects it.

What we need

One recent bill per site, your meter point numbers, and ideally half hourly data through your portal or a letter of authority.

The same data does a second job. It is what turns a modelled estimate for solar or battery storage into something built on how each of your buildings actually runs.
