How To Read A Business Energy Bill

Business energy bills can look complicated. There are reference numbers, multiple line items, charges with unfamiliar names, and a lot of numbers that aren't obviously connected to each other.

But once you know what each part means, a bill becomes much easier to read — and much easier to check for errors.

Here's a plain English guide to the main elements you'll find on a business electricity or gas bill.

The standing charge is a fixed daily fee that your supplier charges for maintaining your energy connection. It applies every day, regardless of how much energy you use — even if you use none at all.

It's expressed in pence per day and is usually shown as a daily rate multiplied by the number of days in the billing period. So if your standing charge is 50p per day and your billing period is 90 days, the standing charge element of your bill will be £45.

The standing charge covers the cost of your connection to the network, the meter, and certain fixed industry costs. It doesn't vary with your consumption.

When comparing energy quotes, always look at the standing charge alongside the unit rate. A very low unit rate with a high standing charge can end up costing more than a slightly higher unit rate with a lower standing charge, depending on how much energy you use.

The unit rate is the price you pay for each unit of energy you consume. For electricity, a unit is one kilowatt-hour (kWh). For gas, consumption is measured in cubic metres or cubic feet and then converted to kWh.

The unit rate is expressed in pence per kWh and is multiplied by your total consumption to produce the energy element of your bill.

Your unit rate should be fixed for the duration of your contract. If it's changed since your last bill, either your contract has ended and you've moved onto Variable Business Rates, or your supplier has made an error.

MPAN stands for Meter Point Administration Number. It's the unique 21-digit reference number for your electricity supply point. It identifies the specific location where electricity is delivered to your premises.

Your MPAN appears in the supply or meter details section of your electricity bill. It stays the same regardless of which supplier you're with or whether your meter has been changed.

Every electricity supplier will ask for your MPAN when you request a quote or switch supplier. It's how they identify your supply in industry systems.

MPRN stands for Meter Point Reference Number. It's the equivalent of the MPAN for gas — an 11-digit unique reference number for your gas supply point.

Your MPRN appears on your gas bill in the supply or meter details section. Like the MPAN, it stays with the supply point permanently and doesn't change when you switch supplier.

Most businesses pay VAT at 20% on their energy bills. This is added to the total of all other charges before the final amount due is calculated.

However, some businesses qualify for the reduced rate of 5%. To qualify, your energy use must be primarily for non-business purposes (for example, if you're a charity or a residential care home), or your consumption must be below a certain threshold — currently 33 kWh per day for electricity or 145 kWh per day for gas.

The reduced rate is not applied automatically. You need to declare your eligibility to your supplier by completing a VAT declaration form. If you believe you qualify and you're currently paying 20%, it's worth checking.

The Climate Change Levy (CCL) is a government environmental tax charged on business energy consumption. It appears as a separate line on your bill, expressed in pence per kWh.

The CCL rate is set by HMRC and changes annually. It applies to electricity and gas (and some other fuels), though the rates differ between fuel types.

Some businesses are exempt from CCL or qualify for a reduced rate. Charities using energy for non-business purposes are exempt. Businesses in energy-intensive industries may qualify for a Climate Change Agreement (CCA) that reduces the CCL rate. Renewable electricity from certain sources may also be exempt.

If you believe you qualify for an exemption or reduction and you're currently paying the full CCL rate, speak to your supplier or an energy consultant.

Your bill will show the meter readings used to calculate your consumption for the billing period. There will be an opening reading (at the start of the period) and a closing reading (at the end). The difference between the two is your consumption for that period.

Each reading will be marked as either actual (A) or estimated (E). An actual reading comes from a meter reader, from you submitting a reading, or from a smart meter. An estimated reading is calculated by the supplier based on your historical usage.

If your bill shows estimated readings, it's worth submitting an actual reading to your supplier. This prevents the estimates from drifting too far from your actual consumption and reduces the risk of a large catch-up bill later.

An estimated bill is one where the consumption has been calculated using estimated rather than actual meter readings. It's marked with an "E" next to the meter reading.

Estimated bills are common for premises without smart meters, particularly if the meter is in an inaccessible location or if the meter reader hasn't been able to gain access.

The problem with estimated bills is that they can be inaccurate — sometimes significantly so. If your supplier consistently underestimates your consumption, you'll eventually receive a large catch-up bill when an actual reading is taken.

If you're receiving estimated bills, submit actual readings regularly — at least every quarter. Most suppliers allow you to do this online, by phone or via their app.

Your tariff is the pricing structure you're on. It determines your unit rate, standing charge, and any other charges that apply to your supply.

On a fixed-rate tariff, your unit rate and standing charge are locked in for the contract term. On a variable tariff (including Variable Business Rates), they can change.

Your tariff name or type should be shown on your bill. If it says anything like "standard variable," "out of contract," "deemed" or "rollover," you're not on a competitively agreed fixed rate and it's worth reviewing your options.

Your contract end date is the date on which your current fixed-rate contract expires. It should be shown on your bill or in your contract documents.

This date matters for two reasons. First, it tells you when you need to act if you want to switch supplier or renegotiate your rates — most contracts require notice of 30 to 90 days before the end date. Second, it tells you whether you're currently in a contract or whether you've already moved onto out-of-contract rates.

If your contract end date is in the past and you haven't arranged a new contract, you're almost certainly on Variable Business Rates. Contact us and we'll help you sort a new deal.

Send us a copy of your bill and we'll go through it with you. We check bills for errors regularly — incorrect unit rates, wrong VAT rates, CCL applied when an exemption should apply, estimated readings that have drifted too far from actual consumption.

There's no charge for this. Call us on 01256 844048 or upload your bill on our website and we'll come back to you with our findings.
