Yes — Octopus Energy supplies gas. Here’s exactly how their gas tariffs work in 2026, what you’ll pay, how the July price cap rise affects gas bills, and how to get £50 credit when you make the switch.
Switch Gas & Electricity — Get £50 Credit →Yes. Octopus Energy supplies both gas and electricity to UK homes. You can switch both fuels together as dual fuel (the most common option), or switch just gas or just electricity separately — entirely your choice.
Octopus is one of the UK’s largest energy suppliers with over 7.7 million customers. They supply gas and electricity across Great Britain and have consistently priced at or below the Ofgem price cap since they launched.
Octopus’s standard gas product is Flexible Octopus — a variable tariff that tracks the Ofgem price cap. Rates change each quarter when the cap is updated. Octopus guarantees it will never charge above the Ofgem cap level.
| Quarter | Price cap (typical dual fuel) | Gas unit rate (cap level) | Gas standing charge (cap level) |
|---|---|---|---|
| January–March 2026 | £1,738/yr | ~6.24p/kWh | ~32p/day |
| April–June 2026 | £1,641/yr | ~6.24p/kWh | ~32p/day |
| July–September 2026 | £1,850/yr ↑ +13% | Rises from 1 July | Rises from 1 July |
| October–December 2026 | Not yet announced | — | — |
The "typical dual fuel household" Ofgem uses for the cap assumes 11,500 kWh of gas and 2,700 kWh of electricity per year. Most of the cap is gas — heating your home accounts for the majority of the £1,850 figure.
Your actual bill depends on your usage and insulation. A well-insulated house or flat will pay significantly less. A large, older, poorly insulated property will pay more.
Most households switch both gas and electricity to Octopus at the same time — this is dual fuel. Here’s how it compares to having separate suppliers:
| Dual fuel (gas + electricity, one supplier) | Separate suppliers | |
|---|---|---|
| Admin | One account, one bill, one direct debit | Two accounts, two bills, two direct debits |
| Pricing | Octopus prices both fuels at or below the cap | Occasionally one supplier is marginally cheaper on a single fuel |
| Smart meter | One smart meter install covers both fuels | May require coordination between two suppliers |
| Referral credit | £50 credit applies to the account regardless of fuels included | Would only count as one referral if both with Octopus |
| Switching hassle | Switch both fuels in one process — Octopus handles everything | Two separate switch processes to manage |
For most people, dual fuel with one supplier is the right call. The pricing difference between suppliers on a single fuel is rarely worth the extra admin — and with Octopus capped at the Ofgem level, you’re never paying above the regulated maximum anyway.
Switch Gas & Electricity to Octopus — Get £50 →This is an important distinction: Octopus’s smart tariffs are electricity-based. There is no equivalent time-of-use or smart tariff for gas.
| Tariff | Fuel | Who it’s for | Gas included? |
|---|---|---|---|
| Intelligent Octopus Go | Electricity | EV owners — 8p/kWh overnight charging | Gas billed separately at Flexible rate |
| Cosy Octopus | Electricity | Heat pump & electric heating owners | Gas billed separately at Flexible rate |
| Octopus Flux | Electricity | Solar + battery owners (currently paused) | Gas billed separately at Flexible rate |
| Flexible Octopus | Gas & electricity | All customers — standard variable | Yes — both fuels on one tariff |
If you’re on a smart electricity tariff like Intelligent Octopus Go, your gas supply stays on Flexible Octopus separately. That’s fine — the savings from the smart electricity tariff are typically large enough that gas being on the standard rate is still a good overall deal.
The appliance you heat your home with has a big impact on which Octopus tariff makes most sense long-term:
Short answer: yes — and here’s why:
Use share.octopus.energy/brave-kiwi-22 — you must click the link for the £50 credit to be tracked. Do not type the Octopus URL directly.
Octopus will ask for your postcode and current meter readings (or MPAN/MPRN numbers from your existing bill). Takes around five minutes.
Select whether you want to switch gas, electricity, or both. Most customers switch both at once — simpler, and the £50 referral credit applies either way.
You don’t need to cancel with your current supplier. Octopus handles the switch entirely. There is no interruption to your gas or electricity supply. The switch typically takes 2–3 weeks.
Around two to four weeks after your first Direct Debit payment, £50 credit is automatically applied to your Octopus account. No code to enter, nothing to claim.
With the July 2026 cap rising 13% to £1,850/yr, a lot of people are asking whether they should lock in a fixed gas rate. The honest answer is nuanced — see our full fixed vs flexible guide, but the short version:
| Octopus Energy | British Gas | |
|---|---|---|
| Gas tariff | Flexible Octopus — at or below cap | Variable — typically at cap level |
| Exit fees (variable) | None | None |
| Trustpilot | 4.8★ Excellent (500,000+ reviews) | ~1.3★ (multiple complaint categories) |
| Which? rating | Best Buy — 7 times since 2018 | Not a Which? Best Buy |
| Smart tariffs | IOG (EV), Cosy (heat pump), Agile | Limited smart tariff options |
| Referral credit | £50 each (£100 split) | No referral scheme |
| App quality | Consistently rated best in class | Frequently cited for poor UX |

Yes. Octopus Energy supplies both gas and electricity across Great Britain. You can switch both fuels to Octopus (dual fuel) or switch just gas or just electricity. Their standard gas product is Flexible Octopus — a variable tariff priced at or below the Ofgem cap.
Octopus’s standard gas tariff is Flexible Octopus — a variable rate that tracks the Ofgem price cap. For April–June 2026, the cap-level gas unit rate is approximately 6.24p/kWh with a standing charge of around 32p/day. From July 2026, rates rise in line with the 13% cap increase to £1,850/yr for a typical dual fuel household. Octopus also offers fixed gas tariffs — rates vary depending on when you switch.
Yes. The £50 referral credit applies when you open a new Octopus Energy account — whether that includes gas, electricity, or both. Switch via share.octopus.energy/brave-kiwi-22 and you’ll receive £50 credit on your account after your first Direct Debit.
For most people, dual fuel with one supplier is simpler and at least as good on price. You get one bill, one account, one direct debit. Octopus prices both fuels at or below the Ofgem cap, so you’re never paying above the regulated maximum. Separate suppliers occasionally offer marginally cheaper rates on a single fuel, but the admin burden rarely makes it worthwhile.
No. Octopus’s smart tariffs — Intelligent Octopus Go and Cosy Octopus — are electricity-based. There is no time-of-use or smart tariff for gas. If you heat with gas, Flexible Octopus (variable, at the cap) is the standard product. If you’re considering a heat pump, Cosy Octopus becomes available once you switch to electric heating — and can save up to £389/yr vs the standard rate.
The Ofgem price cap rises 13% from July 2026, from £1,641/yr to £1,850/yr for a typical dual fuel household. Gas makes up the larger share of the cap figure, so households with high gas use (large homes, poor insulation) will see the biggest pound increase. A typical household using 11,500 kWh of gas per year should expect gas costs to rise by around £100–£150/yr from July.
No. Switching energy supplier does not interrupt your gas supply at any point. The gas arriving at your home is the same — it travels through the same pipes regardless of which company bills you for it. Octopus contacts your old supplier and handles the switch. You just need to submit a meter reading on switch day.
Yes. You can switch gas only to Octopus without changing your electricity supplier. However, if you later want to access smart electricity tariffs like Intelligent Octopus Go or Cosy Octopus, you would need your electricity supply with Octopus too. Most customers find it simpler to switch both at once.
