Why Try To Understand Business Energy Bills?

The greatest benefit of understanding your company’s energy bills is finding ways to save money for your business. When you’re aware of the tariff you’re on and the amount you’re being charged for every unit of electricity or gas you’ll be able to determine whether you’re paying over the odds.

What Is Included On A Business Energy Bill?

How Do I Know Which Tariff My Business Is On?

The first thing to know about understanding your bill is to work out the tariff that you’re on. You should find this on the bill, usually on its front page. If you’re on a standard tariff, this is a red flag. Usually, this is the worst kind of tariff, with fluctuating prices and no benefits or perks. On the upside, however, you won’t be tied into a standard tariff, so you’ll be free to change at any time.

How Do I Know How Many Units I Am Consuming?

Electricity and gas units are measured in kilowatt-hours (or kWh). Your bill will tell you the number of kilowatt hours you used during your bill period. This information will tell you which times of the year you’re using more energy so you can reduce your usage.

Convert Gas Units to kWh

Your gas meter

Shown on your bill - usually between 37.5 and 43

1,122.06 kWh

How that's worked out

Volume correction: 100 × 1.02264102.26
Multiply by calorific value: 102.26 × 39.54,039.43 MJ
Convert to kilowatt hours: 4,039.43 ÷ 3.61,122.06 kWh

This is the same formula printed on gas bills. The volume correction (1.02264) adjusts for temperature and pressure; the calorific value is the energy content of the gas and varies slightly by region and over time.

What’s The Difference Between a Standing Charge and a Unit Rate?

A unit rate is the amount you need to pay for every unit of energy you use. This is measured in kilowatt-hours. A standing charge is a flat rate paid to the supplier to cover getting energy to your property. Whilst the unit rate can fluctuate based on how much energy you use, the standing charge does not.

How Do I Pay My Business Energy Bill?

You’ll see the payment method you’re using outlined on your bill too. If it isn’t monthly direct debit you might want to consider making the switch as this is widely regarded as a cheap way to pay for your bills.

What Are My MPRN And MPAN Numbers?

Two other details on your energy bill are your MPAN and MPRN numbers. These are unique to your meters and make it easy to identify which meter is which when you’re switching energy suppliers.

Your MPAN (Meter Point Administration Number) is for your electricity meter and is sometimes called an Electricity Supply Number. It’s a 21-digit number split into sections and should be located on your bill (usually in one of the corners).

Your MPRN (Meter Point Reference Number) is a unique number for your gas meter. It’s 6 to 10 digits long and should also appear on your energy bill.

Note that these numbers are not the same as your customer account number.

Is My Business Energy Bill Too High?

A useful sense check is to compare your annual spend with what similar-sized businesses pay. The table below shows average annual gas and electricity bills for UK businesses by size, based on typical usage for each. Find the row that matches your consumption (your bill or your Annual Quantity will tell you this) and compare the figure with your own total. Paying somewhat more or less is normal, since rates vary with meter type, location and contract timing, but if your bill is well above the average for your size, it’s a strong hint that better rates are available.
