Cheapest Fixed Gas Tariff UK 2026: Compare Rates
Side-by-side unit rates and standing charges across major suppliers. Updated July 2026, with the July cap rise.
Why the July 2026 Cap Makes Fixed Tariffs Compelling
, Ofgem’s price cap is £1,663/yr for a typical dual-fuel household paying by direct debit. That is a £221 increase on the previous April–June 2026 cap of £1,641/yr. Gas bears the brunt: the capped gas unit rate is now 7.33p/kWh with a daily standing charge of 29.04p/day. In practice, gas spend for a typical home (11,500 kWh/yr) has climbed by roughly 24% year-on-year, while electricity rose about 5%.
The result is that fixed tariffs pricing at or below 7.33p/kWh per unit are now objectively cheaper than sitting on the default cap tariff. The best fixes below sit roughly 10–14% below the £1,663 cap for a typical home — fix today and you save that gap immediately. Around 22 million accounts (approximately 40% of households) are already on fixed deals and are unaffected by this rise. If you are still on a standard variable tariff, switching to a fixed deal now locks in a lower rate straight away.
Ofgem confirmed this rise on 27 May 2026. Looking ahead, Cornwall Insight forecasts the next cap (from 1 October 2026) at around £1,701–£1,747 (analyst range)/yr (current-TDCV basis), so a well-priced 12-month fix can shield you from further increases too. The comparison table below shows illustrative rates from reputable suppliers so you can judge the spread quickly.

Gas-Only vs Dual-Fuel Fixed Deals
Most households choose a dual-fuel deal where gas and electricity come from the same supplier. However, some suppliers price their gas-only fixed tariffs differently, and it can pay to compare them separately if you already have a competitive electricity deal.
Gas-Only Fixed Tariff
- Switch just your gas supply independently
- Useful if your electricity deal still has time to run
- Some suppliers offer sharper gas-only unit rates
- No bundle discount applies
- Manage two supplier accounts separately
Dual-Fuel Fixed Tariff
- Gas and electricity fixed together in one deal
- Single monthly bill and one point of contact
- Often includes a small multi-fuel discount (typically £30-50/yr)
- Locks in both unit rates simultaneously
- Best choice if both your gas and electricity are on the cap
With the July 2026 cap having pushed gas bills up by around 24%, switching both fuels to a fixed dual-fuel deal while strong rates are available makes clear financial sense for most households still on the variable rate. If your electricity is already on a competitive fixed rate, a gas-only fix is a practical alternative.
One important note: as of April 2026, GivEnergy has entered administration. Do not consider GivEnergy for any energy supply or battery storage products at this time. The reputable fixed-rate suppliers to compare include Octopus Energy, E.ON Next, EDF, OVO, British Gas, Utility Warehouse, and Good Energy.
Switching: The Short Version
If you already know how to switch and just want the rate comparison, the process is brief: compare tariffs, accept an offer, and your new supplier handles the rest. Key points:
- Energy Switch Guarantee: switching completes within 5 working days with zero supply interruption.
- 14-day cooling-off period: you can change your mind within 14 days of signing up, no penalty.
- Exit fees: all the tariffs listed above carry no exit fee, so you can switch away again if a better deal appears.
- Meter reading tip: if you took a meter reading on 30 June, the cheaper April–June cap covered your usage up to that date — submit it to your supplier so you are not estimated onto the higher July rate for June usage.

Frequently Asked Questions
What is the cheapest fixed gas tariff available in July 2026?
Based on illustrative market data, E.ON Next Fixed 12M is currently among the cheapest at approximately 6.24p/kWh unit rate and around £1,602/yr for a typical home — roughly 14% below the £1,663 cap. Octopus Energy 12M Fixed is close behind at roughly £1,632/yr. Exact rates depend on your region and payment method; use the comparison form above for a personalised quote.
Does the July 2026 price cap rise affect fixed deals?
No. The July rise only affects customers on the standard variable tariff (SVT). Around 40% of accounts are already on fixed deals and are unaffected — you keep paying your agreed rate for the length of your fix regardless of the cap change. Only if you are on the variable cap tariff do your rates go up.
What is the Ofgem gas unit rate?
the Ofgem price cap sets the gas unit rate at 7.33p/kWh and the gas standing charge at 29.04p/day. This represents about a 24% increase in gas costs versus the April–June quarter. Households on fixed deals below this level continue paying their agreed rate regardless of the cap change.
How much more is the July 2026 cap per month and per year?
For a typical dual-fuel home on direct debit, the cap rose by £221 a year — about £18 a month — from the previous £1,641 (April–June) to £1,663, a 13.5% increase. Gas rose about 24% and electricity about 5%, which is why gas-heavy homes feel the biggest jump.
Is a fixed gas tariff better than the Ofgem price cap right now?
Yes for most SVT customers. the cap gas unit rate is 7.33p/kWh, and several fixed tariffs available today sit below that. If you fix now you lock in a lower unit rate immediately and are protected from any further cap rises during your fixed term. The best fixes are roughly 8–14% below the £1,663 cap for a typical home.
Should I choose gas-only or dual-fuel fixed?
Dual-fuel fixed deals are usually the most convenient and often include a small multi-fuel discount. Choose gas-only if your electricity contract still has a competitive fixed rate running and you do not want to exit it early. For most households whose electricity supply is on the standard variable cap, switching both together to a dual-fuel fixed deal offers the best combination of savings and simplicity.
Do fixed gas tariffs have exit fees?
Many current fixed tariffs in July 2026 carry no exit fee, including those from E.ON Next, Octopus Energy, EDF, British Gas, OVO, and Utility Warehouse. Always check the specific tariff terms before signing, as some longer-term deals (18M or 24M) may include a fee. No-exit-fee deals let you switch again if rates fall further.
How long does it take to switch to a fixed gas tariff?
Under the Energy Switch Guarantee, the switch completes within 5 working days with no interruption to your gas supply. There is also a 14-day cooling-off period during which you can cancel without penalty. The July cap rise is already in effect, so the sooner you switch off the variable rate, the sooner you stop paying the higher capped price.
Will energy prices fall later in 2026?
Not on current forecasts. The next cap review takes effect on 1 October 2026, and Cornwall Insight currently forecasts it at around £1,701–£1,747 (analyst range)/yr (current-TDCV basis) — slightly higher again rather than lower. Fixing now can therefore protect you from a further autumn increase, though forecasts can change before Ofgem confirms the October figure.
What is a typical annual gas bill for a UK home in 2026?
A typical UK home uses around 11,500 kWh of gas per year. Under the previous April–June 2026 cap the typical dual-fuel bill was £1,641/yr. the cap is £1,663/yr, meaning gas bills increased by around 24% for households remaining on the variable rate.
Which suppliers should I avoid when fixing in 2026?
GivEnergy entered administration in April 2026 and should not be considered for energy supply. Stick to established, financially stable suppliers such as Octopus Energy, E.ON Next, EDF, OVO, British Gas, Utility Warehouse, and Good Energy when comparing fixed gas tariffs in July 2026.
