Compare Business Gas Prices

Gas supply for businesses uses the same physical pipes and national grid as domestic properties. The gas itself is identical. The commercial framework around it is what changes.

When a supplier provides gas to a business, they’re dealing with a commercial entity, not an individual consumer. That shifts the legal framework. The protections available to householders, including the Ofgem price cap, don’t apply. There’s no published tariff to pick from. Instead, suppliers assess each business individually before quoting: your annual consumption, your meter type, the credit profile of your company, and your location on the network all factor in.

The other difference that catches people off guard is the contract. Once you agree to a business gas contract, it’s legally binding immediately. There’s no statutory cooling-off period like you’d get on a domestic deal. That means it’s worth understanding what you’re signing before you sign it.

Your business gas price is built from four parts: the unit rate you pay per kWh of gas used, a daily standing charge for being connected to the gas network, Climate Change Levy at 0.801p per kWh (April 2026), and VAT at 20% (or 5% if your business qualifies as a very low user or a charity).

The unit rate itself isn’t a single market figure. Suppliers build it from wholesale gas prices on the day you ask, your annual consumption, your site’s location, your credit profile, and how long you’re willing to commit. That’s why two businesses next door can end up with different numbers on the same afternoon.

For a full breakdown of each component and what moves it, see our guide on how business gas prices are calculated.

A business gas bill looks busier than a domestic one, but the core information is the same. Once you know where to look, it takes a couple of minutes.

At the top: your account number and your MPRN (Meter Point Reference Number). The MPRN is a unique identifier for your gas supply point. Not the meter serial number, not your account number. The supply point. You’ll find it on every bill, and you’ll need it any time you want quotes, want to switch, or need to raise a dispute. Worth knowing where it is.

The billing period tells you what dates the bill covers. Next to that, the meter readings. Check whether they’re marked as actual (A) or estimated (E). Estimated readings are where billing disputes start. If they’re estimated, it’s worth submitting a real reading before you pay.

Below that: your unit rate multiplied by your consumption in kWh, your standing charge multiplied by the number of days in the billing period, the Climate Change Levy as a separate line, then VAT on the total.

One thing to check periodically: compare the unit rate on your bill against what your contract says. Billing errors aren’t common, but a fraction of a penny per kWh adds up across twelve months of gas. For a line-by-line walkthrough of every figure on a gas bill, see our guide on how business gas bills are calculated.

Most small and medium businesses end up on a fixed-rate contract. You agree a unit rate and standing charge for a set period, typically one to three years. The rate doesn’t move regardless of what wholesale prices do. Budgeting is straightforward.

Variable-rate contracts track the market. Your rate shifts up or down with wholesale gas prices, usually quarterly. Fewer businesses choose these because the unpredictability makes planning harder, but in a falling market they can work out cheaper than a fixed rate agreed when prices were higher.

For larger consumers, flexible contracts let you buy gas in tranches at different times, spreading your purchasing across the market rather than locking everything in at one point.

Here’s the thing about fixed rates, though. They aren’t automatically the safe choice everyone assumes. You’re paying a premium for that certainty. The supplier has priced in their risk, their margin, and a buffer. If wholesale prices drop significantly during your contract, you’ll watch businesses on newer deals paying less. That happened to plenty of companies that locked in during late 2022.

What really matters is knowing what happens when any contract ends. If it expires and you haven’t arranged a new one, your supplier moves you onto an out-of-contract rate. If there was never a negotiated contract on your meter at all, you’re on a deemed rate. Either way, you’re looking at 50 to 80% more than a negotiated deal. Sometimes more.

Many businesses don’t realise their contract has expired until the bill arrives. Some suppliers bury renewal notices in routine emails. Others have auto-renewal clauses that roll you onto terms you didn’t actively choose. Keeping track of your contract end date is one of the simplest and most commonly neglected things a business can do.

The type of meter on your wall determines how your consumption data reaches your supplier, how accurate your bills are, and what tariff structures you’re offered.

A credit meter is the most basic. It records gas usage, and someone submits readings periodically. If nobody does, the supplier estimates, and estimated bills are where problems start. Overestimates mean you’re overpaying upfront. Underestimates mean a catch-up bill later.

Smart meters send readings automatically. No estimates, no manual submissions, no arguments about accuracy. For most small and medium businesses, getting a smart meter installed is straightforward and usually free.

AMR meters (automated meter reading) are common on larger sites. They transmit detailed consumption data at regular intervals, which matters when your contract negotiations depend on your usage profile.

For larger businesses, your load factor (the ratio between your actual usage and your theoretical maximum) affects pricing. A steady, predictable pattern gets better rates because suppliers find it cheaper to serve. Your maximum demand (the peak your site draws at any one point) affects infrastructure charges. If you’re running a factory, a hotel, or a warehouse, these numbers turn up in your quotes and they’re worth understanding.

Comparing suppliers is about more than just finding the lowest price.

You should consider:

• Unit rate and standing charge
• Contract length and renewal terms
• Supplier service and billing accuracy

Wholesale gas is the single biggest component of your unit rate, and it moves constantly. Understanding what drives it helps you time a procurement decision and judge whether a quote is strong, average, or weak.

Five factors dominate UK wholesale gas pricing.

Global LNG demand. The UK imports liquefied natural gas through Isle of Grain, South Hook and Dragon. When Asian spot prices rise, LNG cargoes divert east and UK prices follow.

Norwegian and European pipeline flows. Around half of UK gas comes from Norway, so any maintenance at Norwegian platforms or stress on continental storage feeds straight into NBP forward prices.

UK and EU storage levels. Low storage entering winter pushes prices up. Full storage in the shoulder months of April to September is usually when quotes look cheapest.

Weather forecasts. Cold snaps spike demand from heating and gas-fired power. Mild winters soften forward prices within days.

Geopolitics. The loss of Russian pipeline gas in 2022 reset European price floors. Middle East conflict and shipping disruption continue to move the market.

A broker earns their fee by tracking these curves and flagging when to fix versus wait. Locking a 24-month contract on a quiet summer day can save a business 10 to 20 percent versus fixing in a winter panic.
