What Is Outgoing Octopus?

Outgoing Octopus is an export-tariff option that Octopus Energy offers to customers with eligible rooftop solar or other small-scale generation. In practice this means the tariff provides a route for the energy you do not use in your home to be measured and credited in some form.

The tariff framework supports both fixed export payments and market-linked arrangements, and eligibility hinges on the way your property’s export is metered and registered. It is important to understand that whether you can join, and how much you may receive, will depend on the specifics of your meter, account and generation pattern; check your account details and ask Octopus Energy about your eligibility rather than assuming outcomes.

Thinking of an export tariff is separate from making the most of the electricity you generate. Many households prioritise self-consumption to reduce import from the grid, and export arrangements typically capture only the surplus you cannot use.

Outgoing Octopus gives a structured method to monetise that surplus, but terms, rates and billing treatments may change and should be verified. If you are exploring this option, assemble details about your inverter, meter type and typical generation so you can compare how an export tariff may align with your broader energy strategy, including any battery or load-shifting plans.

The first practical hurdle is matching your physical metering to the tariff’s requirements. Export tariffs normally need a method to measure exported energy accurately—this can be a smart import/export meter, a separate export meter, or a compatible inverter reading that Octopus Energy is prepared to accept. Not every meter configuration is accepted automatically, so check your meter type and export-reading capability.

Your existing smart meter may record export, but the accuracy, firmware and registration details matter. Make a note of meter serials, MPAN or customer reference numbers, and the inverter model; these pieces of information help Octopus confirm whether your setup can be enrolled and what, if any, additional metering work may be required.

On the account side, some export options are linked to the type of import tariff you have or wish to choose, and there may be specific onboarding steps to register export measurements on your Octopus account. It is sensible to check the account status and any pending meter communications in your online dashboard and to ask Octopus Energy what documentation they need to activate export payments.

If an installer recently commissioned the system, ask them for the export metering paperwork and any commissioning certificate, because Octopus may require confirmation that export metering is live before accepting a tariff application.

Outgoing Octopus describes both flat-rate and market-linked export structures; understanding the operational difference helps you set realistic expectations. A flat-rate export pays a fixed amount per kilowatt-hour exported, which tends to make short-term forecasting simpler because the per-unit payment does not change with market swings. Market-linked export ties the payment to wholesale or time-varying prices, which can be higher or lower at different times of day.

That structure may suit generators whose export profile aligns with periods of higher market value, but it also introduces variability. Check the requirement for interval data and whether your export meter supplies half-hourly or hourly readings, since market-linked settlement typically needs detailed export timestamps to calculate credits accurately.

When considering which structure to prefer, think about how predictable your export volumes are and how much volatility you are willing to accept. If your solar exports are concentrated in predictable midday hours, a market‑linked approach may sometimes capture stronger value, depending on wholesale patterns, whereas a flat rate can be attractive for its simplicity.

Use past generation records to model each option rather than relying on headline descriptions alone. You may also wish to ask Octopus Energy whether they provide customer tools, sample calculations or historical market data to help you simulate likely outcomes for both export structures.

Assessing fit starts with realistic estimation of how much electricity you export across seasons. High self-consumption households—those who use most of their own generation straight away or store it in a battery—may have limited exported volumes and so accrue smaller export credits, whereas homes with daytime absence often export more. Consider whether you have a battery, an electric vehicle that charges during the day, or flexible loads you can time to use generation; these change the balance between import savings and export receipts.

Also factor in the import tariff you would remain on because the net benefit is the combination of reduced import and any export payments. Model likely hourly flows for a typical summer and winter week to get an informed picture rather than relying on single-day assumptions.

Operational and administrative aspects matter too: if your export meter requires a separate installation or registration step, there may be short delays or costs before payments start. Network constraints, inverter settings that limit export, or contractual limits on export volume can affect practical outcomes, so check your inverter’s export cap and any instructions from your installer.

If you are uncertain about how your household’s habits interact with an export tariff, collect a week or month of generation and consumption data and ask Octopus Energy to comment on how that pattern might map to the Outgoing Octopus options available to you.

Before you contact Octopus Energy or a switching adviser, gather key documents and logs to speed up any eligibility checks. Useful items include recent inverter generation reports, export and import meter serial numbers, your MPAN or supply address, the installer’s handover paperwork and commissioning date, and any certificate that confirms your export meter is live.

Having at least a month of generation and consumption figures makes early modelling more accurate; many inverters and smart meters can export CSV or app-based reports. Keep a clear copy of any correspondence with your installer about the meter type and any export-limiting settings, because Octopus may request these during the onboarding process.

Once your records are ready, the next safe steps are straightforward: check the current Octopus tariff pages to see which export options are active, review your online account for meter registration status, and ask Octopus Energy to confirm eligibility and the steps needed to join Outgoing Octopus. If your metering needs work, ask Octopus what they require and whether they can arrange or recommend a meter upgrade.

If you are unsure how export payments will interact with your chosen import tariff or any planned battery, request a simple scenario analysis from Octopus or discuss it with your installer so you can make a measured decision based on documented data rather than assumptions.
