Two headlines can describe exactly the same energy bill. One says £1,663. The other says £1,862. Same quarter, same supplier, same unit rates, yet a gap of almost £200 depending on which figure you happen to read. If that looks like a typo, it isn't, and understanding why both numbers exist is the key to making sense of the UK natural gas price story this year.

The £1,862 figure is Ofgem's price cap for a typical household between 1 July and 30 September 2026, and it's the number that lines up properly with every quarter that came before it. For a lot of households with gas central heating, it's also a far more realistic estimate of the real bill than the smaller £1,663 figure Ofgem now leads with.

This article unpacks where the £1,862 figure actually comes from, what changed behind the scenes to create two versions of the same cap, what it means for your bill for the rest of 2026, and why none of it offers any protection at all if you're paying a business gas or electricity bill rather than a household one.

The UK Natural Gas Price and the Ofgem Cap aren’t the Same Thing

Before untangling the £1,862 figure, it helps to separate two things that get talked about as though they are one and the same: the UK natural gas price and the Ofgem price cap. They're related, but they aren't interchangeable, and mixing the two up is the root of a lot of energy bill confusion.

What "UK natural gas price" actually means

When people, and headlines, refer to the UK natural gas price, they usually mean one of two things. The first is the wholesale price: what suppliers pay to buy gas on the international market, quoted in pence per therm at the National Balancing Point (NBP), the UK's wholesale gas trading hub. The second is the retail price: what you, or your business, actually pay per kilowatt hour on a bill.

Wholesale prices move constantly, driven by LNG cargo deliveries, Norwegian pipeline flows, storage levels and the weather. Retail prices move far more slowly, because suppliers buy gas months or years ahead and Ofgem's cap uses an averaged wholesale price from several months earlier. That lag is why your bill can stay high even after the news reports that wholesale gas has fallen, and why today's UK natural gas price won't show up on your bill until later in the year.

What the Ofgem cap does, and does not, control

The Ofgem price cap does not put a ceiling on your total bill. It caps the maximum unit rate (pence per kWh) and daily standing charge that suppliers can charge customers on a standard variable or default tariff. Use more energy, and you pay more, cap or no cap. The cap also only applies to domestic customers in England, Scotland and Wales on those default tariffs, around 22 million households, while anyone on a fixed deal, and every business account of any size, sits outside it entirely.

Where the £1,862 Figure for Q3 2026 Actually Comes From

Ofgem quietly changed its idea of a "typical" household

From 1 July 2026, Ofgem revised the Typical Domestic Consumption Values (TDCVs) it uses to convert unit rates into a single headline bill figure. These are the assumed annual usage numbers for a medium-use home, and they hadn't moved since 2023.

Falling household energy use is genuine, thanks to better insulation, efficient appliances and milder winters, so this isn't creative accounting so much as Ofgem catching up with reality. But it has one side effect: on the new, lower TDCVs, the July to September 2026 cap comes out at £1,663, while the exact same unit rates and standing charges, run through the older 2023 benchmark, produce £1,862. Both numbers describe identical prices; nobody's unit rate changed. The whole difference sits in the assumed usage used to build the headline.

Why £1,862 is the number worth paying attention to

For a like-for-like comparison with every quarter before July 2026, including the £1,641 cap for April to June, £1,862 is the figure that lines up properly. It's also the closer estimate for any household with gas central heating, since actual consumption there still sits nearer the old 11,500 kWh benchmark than the new 9,500 kWh one. Measured this way, the rise from Q2 to Q3 2026 comes to £221, or 13%, and gas did almost all of the damage.

The Full Picture: Unit Rates Behind the Q3 and Q4 2026 Cap

Headline numbers only tell half the story, so here's what actually sits behind the cap for the current quarter and the one that follows it.

Why gas outpaced electricity

Quarter on quarter, the gas portion of the cap rose by around 24%, while electricity rose by roughly 5%. That imbalance matters if you're trying to understand the UK natural gas price specifically, rather than energy bills in general, because it shows the pressure sits squarely in gas, not power.

Behind that rise sits the wholesale market. UK winter 2026 season-ahead gas has been trading at around 178p per therm through early September, well above the 40 to 50p per therm that was normal before 2021, though still far under the 500p-plus spikes of the 2022 crisis. One structural quirk makes the UK especially sensitive to these swings: Britain holds only around ten days of gas demand in storage, against roughly 90 days in Germany, so the UK natural gas price reacts quickly to any hiccup in Norwegian supply or global LNG cargoes rather than being cushioned by a deep national reserve.

What the £1,862 Figure Means for Your Actual Bill

A worked example

Take a medium-use household on the old TDCV benchmark: 2,700 kWh of electricity and 11,500 kWh of gas a year, on a standard variable tariff, paying by Direct Debit. At the confirmed Q3 2026 rates, that works out to roughly:

• Electricity: about £705 in usage plus £209 in standing charge = £914

• Gas: about £843 in usage plus £106 in standing charge = £949

• Total: approximately £1,862 (small differences come down to rounding)

If your household uses less gas, say a well-insulated flat closer to the new 9,500 kWh benchmark, your real bill will land closer to £1,663. If you're heating a larger or older property, expect to land above £1,862, not below it. The only way to know for certain is to check your own annual kWh figures against these rates rather than relying on either headline number.

If you're on a standard variable tariff

There's nothing to action here beyond understanding the figure. Your supplier applies the confirmed rates automatically. What is worth doing is checking whether a fixed rate beats the cap for your own usage pattern, which the next section covers.

If you already pay a fixed rate

Around 11 million UK households, roughly 35% of the market, sit on fixed tariffs that the cap's quarterly moves don't touch directly. If you locked in a rate below today's cap unit prices, you're currently ahead. If your fixed deal is ending soon, though, don't assume renewing automatically is the safest option. Compare it against both the current cap rate and the best fixed energy deals on the market before you commit to anything.

One more thing worth knowing for Q4: from 1 October 2026, the government under Prime Minister Andy Burnham is cutting VAT on domestic electricity from 5% to 0% until 31 March 2027, worth around £45 a year to a typical household. That's part of why the October rise, to £1,723 (new basis) or £1,935 (like-for-like), looks smaller than the wholesale gas increase alone would suggest. Gas VAT stays at 5%, so the saving only touches the electricity side of your bill.

Fixed Energy Deals vs Riding the Cap: Which Wins Right Now?

With the gas unit rate climbing again for Q4, more households and businesses are weighing up fixed energy deals against simply staying on the cap. Neither option is right for everyone, so here's how the two compare.

Table 3: fixed energy deals compared with staying on a cap-linked standard variable tariff.

A few habits make the decision easier, whichever way you're leaning:

1. Compare your real usage, not the headline figure. Work out your own annual kWh from a recent bill, since the £1,862 versus £1,663 gap shows how misleading a single average figure can be.

2. Check what a fixed deal actually costs at your usage, not just its advertised unit rate, before assuming it beats the cap.

3. Look at exit fees and contract length alongside the price. A slightly higher rate with no exit fee can beat a cheaper one you can't leave.

4. Where you can, fix ahead of winter rather than during it. Winter season-ahead wholesale prices are typically higher than the following summer's.

5. Reassess at renewal rather than setting and forgetting. A fixed energy deal that beat the cap a year ago may not beat it today.

6. Read the standing charge as closely as the unit rate. Two suppliers quoting the same headline price can split the cost very differently.

One Big Exception: The Cap Doesn't Touch Business Gas at All

Everything above describes what happens to household bills. If you run a business, none of it applies to you directly, and that's worth sitting with for a moment.

There is no Ofgem price cap for business gas or business electricity. Commercial accounts of any size are priced on wholesale market conditions, your credit standing and how well you negotiate. The 13% jump behind July's £1,862 figure, and the further rise built into Q4, land on a business account in full, with no cap softening the edges and no VAT relief either, since October's cut applies only to domestic and a narrow band of qualifying non-domestic use, not standard commercial supply.

The one piece of protection businesses do get is a limit on how punishing a deemed or out-of-contract rate can be under Ofgem's SLC 7.3 rule, the default tariff you're moved to if a contract lapses without a renewal in place. "Not unduly onerous" is a long way from a genuine cap, and out-of-contract rates routinely sit 30% or more above a negotiated deal.

Practically, that means the wholesale swings behind the UK natural gas price matter more, not less, once you're paying a business bill. Comparing your options through a service like SwitchUrEnergy's business gas comparison, and fixing a rate ahead of your renewal date rather than drifting onto a deemed tariff, is one of the biggest levers most businesses have over their energy costs.

How to Find the Best Energy Company for Your Situation

Whether you're comparing fixed energy deals for a household or sourcing a new contract for a business, the best energy company isn't necessarily the one with the lowest headline unit rate. A few other things are worth weighing up before you sign anything:

• Contract length and exit terms: a slightly higher rate with no exit fee can beat a rock-bottom rate you can't leave once a cheaper deal appears.

• Standing charges: two suppliers can quote the same unit rate with very different daily charges, which matters more the less energy you use.

• Customer service and complaints record: Ofgem and the Energy Ombudsman publish supplier performance data that's worth a quick check before signing.

• Renewal flexibility: ask whether the supplier, or your comparison service, will flag your renewal window ahead of time, since missing it is exactly what pushes an account onto an expensive deemed rate.

• Clear, side-by-side comparisons: a good comparison service shows contract length, exit fees and standing charges next to the headline price, not the headline price on its own.

Frequently Asked Questions

Why do I see both £1,862 and £1,663 for the same quarter?

Both describe the same unit rates for July to September 2026. £1,663 uses Ofgem's revised, lower Typical Domestic Consumption Values from 1 July 2026. £1,862 uses the older 2023 benchmark and compares properly with every quarter before the change.

Does the Ofgem price cap limit my total bill?

No. It limits the unit rate, and standing charge suppliers can charge on standard variable and default tariffs. Use more energy and your bill still rises, cap or no cap.

What is the Ofgem price cap for October to December 2026?

£1,723 on Ofgem's current benchmark, or £1,935 on the old benchmark for like-for-like comparison with £1,862. That's a rise of roughly 4%, driven mainly by an 8.7% jump in the gas unit rate.

Does the price cap protect business gas and electricity bills?

No. The cap applies only to domestic customers on standard variable or default tariffs. Business energy contracts are priced on wholesale conditions and negotiated terms, with no cap at all.

Should I switch to a fixed energy deal before winter?

It depends on your appetite for risk. A fixed deal priced below current cap unit rates removes the risk of a further rise, while staying on the cap can pay off if wholesale prices ease instead. Comparing both against your own usage is the only reliable way to decide.

What is actually driving the UK natural gas price right now?

Global LNG supply and demand, Norwegian pipeline flows, European storage levels and the weather. The UK's shallow storage, around ten days of demand against roughly 90 in Germany, makes it especially quick to react whenever any of these shift.

How often does the Ofgem price cap change?

Every three months, with new rates from January, April, July and October, announced roughly six weeks before each one takes effect.

Final Words

The £1,862 figure isn't a mistake or a misprint. It's a genuine reading of the July to September 2026 price cap, just measured against an older, more familiar usage benchmark than the one Ofgem now leads with. Whichever number you focus on, the underlying story is the same: gas drove the rise far more than electricity did, wholesale prices remain above pre-2021 norms, and the UK natural gas price is still reactive enough to weather and global supply shifts that a further move by January is entirely possible.

For households, understanding both figures means you can judge your own bill properly and decide with confidence whether a fixed energy deal beats sitting on the cap. For businesses, there's no cap to fall back on at all, which makes comparing suppliers and locking in a rate before renewal even more important.
