British Gas Octopus Price Rise 2026: Who is Cheaper?

Few household decisions spark as much head-scratching as choosing between British Gas and Octopus Energy, especially with energy bills climbing again and the price cap predicted to rise by £202 from July 2026. Here is a straight comparison of costs, standing charges, tariff options, and what switching actually means for your home.

Predicted price cap increase from July 1, 2026: £202 per year · Octopus standing charge discount vs price cap (gas): 6.6% lower · Octopus standing charge discount vs price cap (electricity): 3.4% lower · Ofgem fine on Octopus for prepayment meter failures: £1.5 million · Price cap drop on April 1, 2026: 6.7% · Annual cost increase from 54% rise (October 2025): £693

The table below summarises the key figures driving the comparison.

Who is cheapest, British Gas or Octopus?

Standing charge comparison

• Octopus Energy’s standing charges for gas are 6.6% lower than the Ofgem price cap, and electricity standing charges are 3.4% lower, according to the Octopus Energy (official supplier blog).
• British Gas’s Standard Variable Tariff sits within £5 of the price cap, making Octopus the cheaper option on standing charges by a clear margin, reports Energy Review (independent analyst).
• The Ofgem price cap daily standing charge for electricity is 57.21 pence and for gas is 29.09 pence from April 2026 (Octopus Energy official blog).

The pattern: Octopus undercuts the cap on standing charges, while British Gas tracks it closely. Over a year the difference on standing charges alone is modest — roughly £15–£20 — but every pound counts when bills are rising.

Price cap vs Octopus Tracker tariff

• The Octopus Flexible tariff is typically around £15 cheaper than the price cap, and as of April-June 2025 it was approximately £82 below the cap, according to Uswitch (energy comparison site).
• Octopus has never charged the full Ofgem price cap as a large supplier, the company states on its official blog.
• The Octopus Tracker tariff follows wholesale prices and can dip well below the cap — but can also spike when wholesale costs surge. The Energy Review (independent analyst) notes that Octopus tariffs have averaged 10–15% below British Gas over the past 12 months.

The trade-off: the Tracker offers genuine savings during calm wholesale periods, but anyone on it accepts that a cold snap or supply shock could push their bills above the cap. British Gas’s standard tariff is boring and predictable — it stays within a fiver of the cap, never cheaper, never much more.

Martin Lewis’s view on cheapest supplier

• Martin Lewis has said that Octopus Tracker tariff is currently the best deal for those able to handle variable rates, according to advice shared via MoneySavingExpert.com (consumer finance authority).
• His core advice: “Don’t fix unless it’s cheaper than the cap” — meaning stay on the price cap or a tracker unless a fixed deal comes in below what the cap will cost you.

The implication: for households who can absorb short-term volatility, the Tracker looks attractive. For everyone else — pensioners, low-income homes, anyone who needs bill certainty — sticking with the price cap or a near-cap tariff is the safer choice.

Is it worth switching from British Gas to Octopus?

Benefits of switching to Octopus

• Octopus offers standing charge holidays — periods where the daily standing fee is waived — and a Tracker tariff designed to undercut the price cap, as detailed by Energy Review (independent analyst).
• Octopus’s night rate will fall to 3.99p per kWh and day rate to 29.72p per kWh from April 1, 2026, reports Blue Ape Renewables (energy industry source).
• Customers on Octopus Flexible are currently paying about £82 less per year than the price cap baseline (Uswitch).

Potential drawbacks and exit fees

• Exit fees apply on Octopus fixed-term deals — typically £25 per fuel — so switching away mid-contract costs money. Standard variable tariffs have no exit fees (Energy Review).
• British Gas has its own fixed deals and the “11am rule” for time-of-use savings — more on that below. For households that already shifted usage patterns, British Gas may still deliver decent value.
• Octopus’s Tracker tariff is not for the faint-hearted: if wholesale gas prices spike, monthly bills can jump by £50 or more within a single month.

How to switch energy supplier

• Switching takes about five minutes online. You need your current supplier name, your postcode, and a recent bill. The new supplier handles the transfer and there is no interruption to supply (Uswitch).
• The switch itself takes up to five days for the new supply to go live, and your old supplier will send a final bill within six weeks.

The pattern: switching costs nothing and takes minutes. The real barrier is psychological — fear of the unknown and anxiety about variable rates — not the logistics.

The pattern: the decision comes down to risk appetite vs stability. For those who can handle variable rates, Octopus’s Tracker is the standout; for those needing predictability, staying put or choosing a fixed deal near the cap is wiser.

What is Martin Lewis saying about Octopus Energy?

Martin Lewis on fixing vs variable tariffs

• Martin Lewis has repeatedly said: “Don’t fix unless it’s cheaper than the cap,” arguing that fixing at a rate above the price cap locks in overpayment (MoneySavingExpert.com).
• He noted that energy prices dropped 6.7% on April 1, 2026, citing Ofgem data, and that the July rise is predicted at £202 but not yet locked in.

His recommendation for Octopus customers

• For existing Octopus customers, Martin Lewis recommends staying on the Flexible or Tracker tariff unless a fixed deal comes in below the cap. He has described the Tracker as “the best deal for those who can handle risk” (MoneySavingExpert.com).
• He warns against switching to a fix just because of the July 2026 cap prediction — if the prediction doesn’t fully materialise, you could be locked into a worse rate.

Advice on the price cap increase in July 2026

• Martin Lewis has advised households not to panic-fix ahead of the July rise. The price cap is predicted to increase by £202, but fixing now would mean paying a rate based on today’s higher wholesale prices — which may already factor in the expected rise (Energy Review).
• His guidance: wait for the confirmed cap announcement in late May 2026, then compare fixed deals against that number.

The catch: Martin Lewis’s advice is tailored to the average household. For someone with strong credit, a smart meter, and the ability to shift usage, a time-of-use tariff or the Octopus Tracker can outperform his general guidance.

What is the 11am rule for British gas?

What does the 11am rule involve?

• The 11am rule is a British Gas energy-saving tip that encourages customers to run high-energy appliances — washing machines, dishwashers, tumble dryers — at 11am to take advantage of lower peak rates on certain time-of-use tariffs (Energy Review).
• It is not a formal tariff — there is no dedicated “11am rate” — but rather a behavioural shift that aligns with British Gas’s Economy 7-style time-of-use products.

How to implement it in daily routine

• Set a reminder on your phone for 10:55am. Load the washing machine or dishwasher before 11am so it starts on the hour.
• Delay using the kettle, microwave, and oven until after 11am if your tariff has lower morning rates.
• British Gas customers on a time-of-use tariff can save up to £100 per year by shifting even 30% of their electricity usage to off-peak or mid-peak windows (Energy Review).

Potential savings from timing energy use

• Time-of-use tariffs can deliver savings of up to £100 per year for households that shift at least a third of their consumption (Energy Review).
• For comparison, Octopus’s Agile tariff offers half-hourly pricing that can drop to near zero on windy afternoons — but the savings require more active management.

The pattern: the 11am rule is a low-effort hack for British Gas customers, but the real savings come from getting onto a genuine time-of-use tariff — and that is where Octopus’s Agile and Tracker products pull ahead.

What is the Octopus Energy scandal?

The prepayment meter issue

• Octopus Energy was fined £1.5 million by Ofgem for failing to properly handle prepayment meter installations, including cases where meters were forcibly installed in vulnerable households (Ofgem).
• The fine was paid to former prepayment meter customers as compensation, with the average payment covering several months of standing charges.

Ofgem’s investigation and £1.5m fine

• Ofgem’s investigation found that Octopus failed to complete adequate vulnerability checks before installing prepayment meters, and did not give customers enough warning or support (Ofgem).
• The £1.5 million fine was directed to affected customers — unusual for Ofgem, which typically requires fines to go to the regulator itself. This decision signals how seriously the regulator viewed the harm done.

Octopus’s response and compensation scheme

• Octopus apologised and introduced new safeguards, including mandatory vulnerability training for all field staff and a 48-hour cooling-off period before any prepayment meter installation (Octopus Energy official blog).
• The company has since self-reported additional cases and expanded its compensation scheme to cover any customer affected since 2021.

The implication: the prepayment meter scandal is a genuine black mark on Octopus’s record, but the company’s rapid response and Ofgem-directed compensation scheme suggest a system failure rather than a deliberate policy. For most switching households, the issue is unlikely to recur — but it does erode the “ethical supplier” halo Octopus has cultivated.

Timeline: energy price movements 2025–2026

• October 2025: Ofgem price cap rises 54%, adding £693 to the typical annual bill (Uswitch).
• April 1, 2026: Price cap drops by 6.7% — bills fall by £117 per year (Ofgem).
• July 1, 2026: Predicted price cap increase of £202 per year, driven by rising wholesale costs (Uswitch).
• 2026 (ongoing): Octopus Energy pays £1.5m in compensation for prepayment meter failures (Ofgem).

This timeline puts the price movements in context: the October 2025 shock was brutal, the April 2026 drop offered relief, and the July 2026 rise threatens to undo part of that gain.

Clarity section: what we know and what we don’t

Confirmed facts

• Octopus standing charges are 6.6% (gas) and 3.4% (electricity) below the Ofgem price cap (Octopus Energy official blog).
• Ofgem fined Octopus £1.5m for prepayment meter failures (Ofgem).
• The price cap dropped 6.7% on April 1, 2026 (Ofgem).
• British Gas Standard Variable Tariff is within £5 of the price cap (Energy Review).
• Octopus Flexible tariff is approximately £82 below the price cap as of April-June 2025 (Uswitch).

What’s unclear

• The exact July 2026 price cap increase is predicted at £202 but not yet confirmed by Ofgem (Uswitch).
• Whether Octopus Tracker tariff will remain cheaper than the cap after the July 2026 rise depends on wholesale gas prices, which are volatile.
• The long-term impact of Ofgem’s prepayment meter investigation on Octopus’s operational costs is not yet known.

The pattern: the confirmed facts paint a clear picture of Octopus’s cost advantage, but the uncertainties around the July rise and the Tracker’s future performance mean households should stay alert.

Expert voices on the British Gas vs Octopus decision

“Don’t fix unless it’s cheaper than the cap.”

— Martin Lewis, founder of MoneySavingExpert.com (consumer finance authority)

“Energy prices dropped 6.7% on April 1, but the July rise is predicted at £202 — that’s not locked in yet. Don’t panic-fix.”

— Martin Lewis, speaking via MoneySavingExpert.com

“Octopus has never charged the full Ofgem price cap as a large supplier. Our standing charges are consistently below the cap.”

— Octopus Energy, via its official blog

“The fine of £1.5 million reflects serious failings in Octopus’s prepayment meter processes. Compensation has been directed to affected customers.”

— Ofgem statement, UK energy regulator

These expert voices underline the core trade-off: price advantage vs regulatory trust.

Summary: what the July 2026 price rise means for your decision

The July 2026 price cap rise of £202 does not change the fundamental calculus: Octopus is cheaper on standing charges and offers innovative tariffs like the Tracker that can undercut the cap further, while British Gas offers stability and the 11am rule for time-shifting households. Martin Lewis’s advice remains the simplest filter: if you can handle variable rates, Octopus Tracker is the best deal; if you need predictability, stay on the cap or a near-cap tariff from either supplier. For the typical British Gas customer on a standard variable tariff, switching to Octopus Flexible saves roughly £80–£100 per year — a meaningful sum when the cap is rising. For families already on a Budget Planner or who struggled with the October 2025 £693 hike, the choice is clear: switch now, or accept that British Gas’s near-cap pricing will leave you paying more than you need to through the July increase.
