Snug Octopus for storage heaters and Economy 7

Snug Octopus matters because many Economy 7 and RTS households are not choosing a tariff for an electric car or a heat pump. They are trying to keep storage heaters, hot water and day/night billing working as old meter controls are replaced.

Octopus describes Snug as a smart tariff for traditional storage heaters. It gives a fixed overnight off-peak window, an afternoon boost and extra off-peak periods when Octopus schedules compatible storage heaters to charge. During those scheduled periods, Octopus says the off-peak price applies to the whole home, not just the heater circuit.

That sounds simple, but the practical question is not just “is Snug cheaper than Economy 7?” It is “can my meter, heater wiring and Octopus account actually support the product?”

Snug Octopus tariff rates and off-peak times

Octopus publishes its October 2026 Snug rates by region. The off-peak price is not an all-day electricity price. Use the official Snug page with your postcode to check your regional day rate, off-peak rate and standing charge before comparing costs. Snug is a variable tariff, so rates can change with notice. If you already use Snug, check your Octopus notice to confirm when any revised rates start for your account.

• 00:30 to 06:30 every night: six hours at the off-peak rate for all electricity used in your home. Octopus says this window stays at those local clock times when the clocks change.
• Scheduled heater charging outside that window: the off-peak rate also applies to other household electricity used during the qualifying scheduled periods.
• A daily one-hour afternoon boost: Octopus schedules extra storage-heater charging to help retain warmth into the evening. It is not a fixed afternoon time that you can assume in advance.
• Other periods: the quoted day rate applies. Manually turning on heater charging at peak times does not create a cheap whole-home slot.

The overnight price window is not a promise that your heaters charge continuously for six hours. Octopus uses your charging preferences to schedule the heating, which may run in shorter bursts. An immersion heater on the same controlled circuit can run with the storage heaters, so ask how the arrangement will affect your hot water as well as room heating.

Is Snug Octopus a new tariff?

No. Octopus announced Snug on 18 November 2024. It is a storage-heater product, not a new name for Cosy or a general overnight tariff for any home. The launch announcement explains its history; use the live product page and your personalised quote for today's prices rather than an old launch savings figure.

Who should look at Snug first

Snug is worth investigating if your main electricity use is storage heating and hot water, you already have or are moving to Octopus and your home has the kind of smart-meter controlled heating circuit Octopus can check during signup.

• You have traditional storage heaters, not a heat pump, gas boiler or panel heaters only.
• Your heaters normally charge automatically rather than relying only on a manual plug-in timer.
• You have, or can get, a second-generation smart meter that supports the required auxiliary load control setup.
• You are comfortable letting Octopus schedule heater charging rather than keeping every heating timer fully manual.
• You will compare the live postcode quote against your current day/night usage split before switching.

If you mainly want cheap EV charging, compare Octopus Go and Intelligent Octopus Go instead. If you have a heat pump, start with Cosy and a home-efficiency check. If you have solar and a battery, check import, export and battery-control compatibility before treating any storage-heater tariff as the answer.

You must live at the property and hold the Octopus energy account in your own name. Half-hourly readings and a compatible SMETS2 auxiliary load control switch (ALCS) are required. A storage-heater brand alone does not establish eligibility, and modern Wi-Fi or app-controlled heaters may not use the meter control Snug needs. Let Octopus check the exact setup; do not open the meter or alter wiring to try to qualify.

Limits, manual boosts and billing checks

The Snug terms in section 2.13, checked on 6 October 2026 and labelled version 1.1, last updated 13 January 2025, set a fair-use maximum of seven hours of managed charging per 24 hours. Octopus reserves the right to charge incremental usage above that limit at the day rate and choose which excess period receives that rate. Do not treat smart scheduling as unlimited cheap heating.

• Meter delays: if a delayed switching response pushes charging outside both the schedule and the overnight window, the day rate can apply to that charging.
• Lost smart control: the terms say heating can fall back to the pre-Snug schedule if Octopus cannot optimise it. Charging outside the overnight window can then cost the day rate.
• Continuing eligibility: removing the compatible heating setup, changing to an incompatible meter or losing active integration authorisation for more than 30 days can mean a move to a standard tariff.
• Third-party flexibility: Snug requires exclusive demand-response rights. The terms prohibit third-party demand-response schemes covering the premises or storage heaters while you remain on Snug.

Use the monthly statement to check the charged rates against your scheduled periods. Octopus warns that the app and in-home display may not immediately reflect smart-tariff adjustments. Keep the schedule and statement if the billed rate looks wrong, then ask Octopus to investigate rather than assuming the display is the final bill.

The checks before you rely on it

Snug versus Economy 7

Economy 7 is the simpler idea: one cheaper period, one dearer period and a meter that records peak and off-peak use separately. Citizens Advice describes seven cheaper hours at night, with exact times depending on the supplier, tariff and where you live.

Snug is more controlled. Octopus says it can schedule compatible storage heaters, add an afternoon boost and apply the off-peak price to the whole home during scheduled heater charging. That makes the meter and control setup more important than it would be on a basic two-rate tariff.

Do not compare the tariffs from a single national example. Use your annual kWh, your day/night split, your postcode quote and your real heating routine. A home that barely uses overnight electricity may be better on a single-rate tariff. A home with old storage heaters and a working smart-meter control setup may have a stronger reason to check Snug.

For a useful annual comparison, multiply the kWh you expect in qualifying cheap periods by the quoted off-peak rate, add the remaining kWh at the day rate, then add a year's standing charges. Repeat with your current Economy 7 prices. An extra afternoon heating session can improve comfort but also add consumption, so compare the expected heating use rather than assuming today's total kWh stays unchanged.

If you already have an Octopus account, use the official Snug page's existing-customer switch journey for the compatibility check. If you are with another supplier, becoming an Octopus customer does not guarantee Snug eligibility. Confirm the meter and heating route before relying on it as the reason to switch.

What to photograph before a meter or tariff change

Storage-heater homes often have the messiest handovers because the meter can be doing more than recording one import number. Take evidence before the change, not after the first bill looks odd.

• the full electricity meter and any separate RTS or teleswitch box
• every import register, including day, night and total screens if shown
• the meter serial number and any labels near the heating circuit
• old bills showing the previous Economy 7 or Economy 10 split
• the time your storage heaters and hot water actually charge
• any installer note from a meter exchange or smart-meter appointment

Citizens Advice says two-rate smart meters can show separate readings and that, if you are unsure which is day or night, you can compare morning and later-day readings. The register that moves during daytime use is the day or peak register.

Where the referral page fits

Use the referral page only after the meter and tariff checks still make Octopus the right move. A referral credit is useful, but it should not be the reason to rush a storage-heater switch before the meter setup is understood.

If your setup checks out, use our referral link for the direct Octopus signup you complete. If the old meter, RTS replacement or day/night register mapping is unclear, pause and get that evidence sorted first.
