Compare Business Gas Prices

Switching business gas supplier is more straightforward than most businesses expect. Once you’ve signed a contract with a new supplier, they handle the transfer with your current supplier on your behalf. There’s no service interruption, no engineer visit, and no change to the physical gas supply.

The transfer typically takes two to six weeks from contract signing. Your meter readings stay with you, your MPRN doesn’t change, and the only material difference is who sends the bill. The wholesale gas reaching your building comes through the same pipes either way.

One critical timing point: you have to give written notice to your current supplier within their termination window. That’s usually 30 to 180 days before contract end, depending on the supplier. Miss that window and you can be rolled onto out-of-contract or deemed rates, which are typically 30 to 50 percent above a freshly negotiated rate. The new supplier can usually help with the notice, but the responsibility sits with the customer.

Wholesale gas prices in the UK reflect the cost of physical gas trading on the National Balancing Point (NBP) market, the UK’s virtual trading hub for natural gas. Unlike your final unit rate, the wholesale price moves daily, sometimes hourly, based on a mix of fundamental and short-term factors.

What moves the wholesale price:

• LNG demand. Global liquefied natural gas demand, especially from Asia, sets the floor for what the UK pays for imports.
• Norwegian pipeline flows. Around 35 percent of UK gas comes from Norway via pipeline. Maintenance outages or flow restrictions move prices fast.
• UK and EU storage levels. Going into winter, storage fill levels are a leading indicator of price stability.
• Weather forecasts. Cold snaps drive demand spikes, especially when they coincide with low wind generation across the wider grid.
• Geopolitics. Events affecting major exporters (Russia, Norway, Qatar, the US) can shift the curve overnight.

Your final unit rate isn’t the wholesale price alone. It’s wholesale plus non-commodity costs plus supplier margin. But wholesale movement is the single biggest driver of how much your renewal quote varies from one week to the next. Timing the fix on a softer wholesale curve is one of the clearest ways a broker adds value.

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.

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

The “best” deal isn’t always the cheapest headline rate. The best deal is the one that fits your consumption profile, your appetite for risk, and your renewal calendar.

Four things usually separate a genuinely competitive offer from one that just looks competitive:

1. A sharper unit rate than your incumbent’s renewal quote. Most existing-supplier renewals carry an unspoken “loyalty tax” — typically 10% to 20% above what a challenger supplier will quote a fresh customer. The best deal usually comes from a switch, not a renewal.

2. Contract length matched to the wholesale curve. Fixed 12-month rates are usually sharpest in summer (low season). Fixed 24-month and 36-month rates are typically sharper in winter, when suppliers want longer commits to hedge volatility.

3. Standing charge that isn’t quietly inflated. Some suppliers compete on unit rate but bury the difference in a higher daily standing charge. Always compare both lines side by side.

4. Exit terms you can live with. A best-deal contract should let you exit if the market moves materially against you. Watch for buyout clauses that lock you in regardless of conditions.

What we’re seeing in the market right now

• Small businesses (under 30,000 kWh/year) are typically winning fixed 12-month deals around 5.0p to 6.5p per kWh + 35p to 50p per day standing charge.
• Medium businesses (30,000 to 150,000 kWh/year) are seeing fixed 24-month deals around 4.5p to 5.5p per kWh.
• Larger sites (150,000+ kWh) should be quoted bespoke. Anyone offering you an off-the-shelf rate at this consumption level is leaving money on the table.

Indicative ranges only. These are not live market rates. The wholesale gas market moves daily. The figures shown were taken as an average from a selection of our supplier panel during April 2026. Your actual quote will vary based on consumption profile, region, credit, contract length, and the wholesale curve on the day you lock in.
