Business gas prices: what you should be paying and how to check
Business gas prices move constantly and most firms quietly overpay. This guide explains how business gas is priced, what drives your rate, and how OptiFlow Watch spots when you are paying too much.
Why business gas prices are so hard to pin down
Unlike home energy, business gas has no price cap and no single published rate. What you pay depends on when you signed, how much you use, your meter type and how hard you negotiated. Two firms on the same street can pay very different rates for the same gas.
That opacity is exactly why so many businesses overpay. A rate that looked fine two years ago can sit well above the market today, and nobody inside the business is watching. OptiFlow Watch is the agent that watches for you.
What drives your business gas price
The unit rate
The price per kwh you pay for the gas itself, set when you agreed your contract.
The standing charge
A fixed daily charge that applies whatever you use, which can quietly add up.
When you signed
Rates are locked to the wholesale market on the day you agreed, so timing matters a lot.
Your usage profile
How much you use and when changes the rate a supplier will offer.
Contract type
Fixed, variable and deemed rates behave very differently, and deemed rates are usually the most expensive.
Being out of contract
If your deal has lapsed you are likely on the highest rate the supplier charges.

Common questions
How are business gas prices set?
Business gas has no price cap. Your rate is set by the wholesale market on the day you sign, plus a standing charge, and depends on your usage and meter.
Why do I pay more than another business?
Because business rates are individually contracted. Timing, usage and whether you are in contract all change the price.
How do I know if I am overpaying?
Compare your unit rate and standing charge against the current market. OptiFlow Watch does this automatically and flags overpaying.
What is a deemed rate?
It is the default rate you pay when you have no active contract. It is usually the most expensive, so it pays to avoid it.
Can OptiFlow help?
Yes. OptiFlow Watch monitors your gas and other bills every month and warns you before you overpay or a contract lapses.
