The renewal letter arrives, the rate looks roughly similar to last year, and most business owners just sign it. It’s understandable – there are seventeen other things demanding attention that morning. But that quiet moment of “fine, whatever” can cost a business several hundred pounds a year, sometimes more, depending on usage and sector.
Gas procurement isn’t complicated, but it does reward the people who bother. And the majority don’t bother, which is partly why suppliers keep renewal rates padded with margin. They’re counting on inertia.
The Way Business Gas Pricing Actually Works
Business gas contracts aren’t priced the same way as domestic ones. Suppliers quote rates based on your consumption history, your location, your meter type, and frankly, how likely they think you are to shop around. A small manufacturing unit in the East Midlands using 50,000 kWh a year is going to face very different pricing dynamics than a restaurant in central Manchester burning through gas for commercial kitchens twelve hours a day.
There’s also the contract length to think about. Fixed-rate deals lock your unit rate for one, two, or three years, which can be smart when wholesale prices are creeping upward but less clever when the market softens. Variable contracts give you flexibility but expose you to market movement. Neither is universally better – it depends on your risk appetite and how closely you’re watching energy markets. Most business owners, fairly reasonably, have better things to do than track gas futures.
Standing charges are another thing that catches people out. Two suppliers might quote an identical unit rate, but if one’s standing charge is significantly higher, the total annual cost tells a different story. You have to look at the whole bill, not just the headline number.
Why Sticking With Your Current Supplier Rarely Pays Off
Loyalty is a concept energy suppliers find deeply useful, mainly because it rarely benefits the customer. Out-of-contract rates, which kick in automatically if you don’t renew or switch before your contract ends, are almost always the worst rates on offer. Some businesses drift onto these for months without realising. The supplier won’t call to flag it.
Switching sounds like more hassle than it is. The actual process, once you’ve found a better deal and signed a new contract, is handled between suppliers. Your gas supply doesn’t get interrupted. The meter stays the same. The main thing you’re changing is who sends the invoice and at what rate.
That said, the comparison part does take some attention. It’s worth having your current contract details to hand, including your annual consumption figure, which you’ll find on your bill, and knowing when your current contract ends. Some contracts have notice periods of 30 to 90 days, so timing matters if you want to avoid rolling onto that out-of-contract rate.
What To Actually Do About It
The most practical starting point is to compare business gas prices using a broker or comparison service that works across multiple suppliers. The advantage there is obvious – you’re seeing a range of rates side by side rather than calling each supplier individually and trying to hold all the numbers in your head.
Brokers sometimes get commission from suppliers, which is worth knowing about, though the better ones are transparent about this and still surface genuinely competitive deals. The question to ask is whether they have access to the whole market or just a panel of preferred partners.
Larger businesses with more complex setups, multiple sites, or high consumption might benefit from going through a specialist energy consultant rather than a standard comparison tool. The deals available at that scale, particularly for businesses using over 73,500 kWh annually (which moves you into the non-domestic meter category), can be meaningfully different and often require direct negotiation.
The Broader Picture
Gas prices have been volatile since 2021, and while they’ve pulled back from the extremes of 2022, they haven’t returned to where they were before. Businesses that got complacent during the cheaper years and didn’t build regular energy reviews into their operations got caught badly when things moved. The ones that came out of that period better were generally those who had contracts in place and were at least paying attention to renewal dates.
It’s not a glamorous thing to spend an afternoon on, reviewing gas contracts and running comparisons. But the numbers involved are real, and the time investment is genuinely modest compared to what you can save if your current rate is uncompetitive.
