Your first month with Octopus

You’ve signed up, the switch has completed and Octopus is now supplying your energy. The first month is mostly about checking the handover is clean: your opening readings, tariff, Direct Debit, smart-meter data and first statement.

Reviewed 26 May 2026: this guide was checked against Octopus guidance on handover meter readings, first Direct Debit payments, credit refunds, Octoplus eligibility and smart-tariff billing evidence. Use it as a first-month checklist rather than a promise that every new account will look tidy immediately.

First-month source check, 26 May 2026

The current source check used Octopus’s handover meter-reading explainer, payment-support page, credit-refund FAQ, Octoplus terms and smart-tariff terms. The practical points are:

• Octopus says an opening meter reading can be submitted up to five days after the supply start date. If it is too late, the handover reading may be estimated.
• The old supplier cannot finalise the closing account until the handover reading is confirmed, and suppliers are expected to issue a final bill within six weeks of leaving.
• Octopus says the first Direct Debit helps open the account in credit. Use the Balance Forecast and the actual first readings before changing the payment too sharply.
• Credit refunds need an up-to-date statement based on readings within the last 30 days, and refunding early credit can mean higher payments later.
• Octoplus needs an electricity supply account, a working electricity smart meter with half-hourly readings and a monthly Direct Debit unless you have a smart prepayment meter.
• For smart tariffs, Octopus billing depends on compatible smart-meter data and tariff terms. Charger, vehicle or app screenshots can help explain what happened, but they are not the final billing record.

The welcome and account setup emails

Octopus will email you around the time your supply starts. Read the early messages rather than filing them away, because they normally cover your account setup, tariff details, meter-reading request, payment information and app access.

The most important message is the opening meter-reading request. Octopus says you can submit an opening read up to five days after your supply start date. If you miss that window, the handover reading may have to be estimated and agreed through the industry process, which can make your old supplier’s final bill harder to check.

Setting up the app

Download the Octopus Energy app once your account is active and log in with the email address you used when signing up.

The app is the easiest place to check your balance, send meter readings, view statements, see usage, change payment details and contact support. If you are on a smart tariff such as Agile, Go or Intelligent Octopus Go, it is also where you will look for half-hourly data, tariff information and smart-tariff settings.

Do not panic if the app looks a little quiet at first. A new account can take a short while to fill with useful data, especially if Octopus is still waiting for opening readings or smart-meter data.

Check your tariff and region

Log into your account and check that the tariff shown matches what you expected to join. If it says Flexible when you expected a smart tariff, or the tariff start date looks wrong, contact Octopus support rather than assuming it will sort itself out.

Also check the standing charge and unit rates against the correct Octopus tariff page for your postcode or region. Energy rates vary by region, so a rate shown for another part of the country may not match your account exactly.

Send the opening meter reading promptly

If Octopus asks for an opening reading, send it as close to the supply start date as you can. This is the reading used to split responsibility between your old supplier and Octopus, so it matters more than a normal monthly reading.

A working smart meter may send readings automatically, but it is still worth checking the app during the first few weeks. If you can see recent daily or half-hourly readings, the connection is probably working. If the account is still asking for manual readings, send them through the app and keep a note or photo for your records. For exact app steps, use our guide to submitting meter readings.

Understand the first bill and final bill handover

Your first Octopus statement normally appears after the account has enough billing information. It should show usage in kWh, the unit rate, standing charge, VAT and payments or credits on the account.

If you used the referral link below when signing up, the referral credit should appear as account credit once the referral has qualified. Treat it as a credit towards your bill, not as a guarantee that the first full month will be free, because actual usage and tariff rates vary.

Your old supplier should issue a final bill using the agreed closing reading. Check that the old supplier’s closing reading and Octopus’s opening reading match or are very close. If they do not, query it quickly, because a mismatch can make one supplier appear to overcharge while the other undercharges.

Check the Direct Debit rather than chasing a perfect balance

Octopus says it takes the first Direct Debit when it starts supplying your energy. The amount is based on expected annual usage, your tariff and standing charges, then spread across the year.

A new account may deliberately start in credit. That is not automatically a problem. Octopus says the first payment helps stop the account falling into debt early, and its Balance Forecast is there to show how the account may move above or below the target balance over the next year.

Once Octopus has real readings, it may suggest a Direct Debit change. Review the suggestion alongside your actual usage, time of year and account balance. If you request a credit refund, Octopus’s current FAQ says the account needs an up-to-date statement based on a meter reading within the last 30 days. Refunding too much early credit can also push the monthly payment back up later. If you want the longer explanation, read our guide to how Octopus Direct Debits work.

Give smart meters time to settle, but keep records

If you already had a smart meter, Octopus still has to connect to it through the industry systems. Some meters start sending readings quickly; others take longer, particularly older SMETS1 meters or homes with signal problems.

During that settling-in period, the meter still measures your energy. Submit manual readings if Octopus asks for them and keep photos if anything looks odd. Once smart readings start flowing, check that electricity and gas both appear correctly and that any export readings are not being confused with import readings.

If you join a smart import tariff, keep the billing evidence separate from app evidence. Octopus’s smart-tariff terms rely on compatible smart-meter data and half-hourly readings; third-party charger, car, inverter or app data can help explain behaviour, but it cannot replace Octopus meter data for billing.

If you do not have a smart meter, Octopus may offer an installation. It can be worth considering because it enables accurate automatic readings, smart tariffs and Octoplus, but it is still sensible to check whether signal, access and tariff eligibility fit your home.

Join Octoplus if you are eligible

Octoplus is Octopus’s rewards programme for customers with electricity supplied by Octopus, a working electricity smart meter sending half-hourly readings and a Direct Debit or eligible smart prepay setup.

Octopoints can be converted to account credit at 800 points to £1. You can earn them through things such as Saving Sessions, free electricity sessions, meter-reading wheel spins and some referral or app activities. Saving Sessions and free electricity sessions depend on your smart-meter data, so they are not guaranteed for every customer from day one.

If something does not look right

Most first-month issues are ordinary handover problems: missing opening readings, a tariff that has not appeared as expected, a smart meter that has not started sending data or a Direct Debit that feels out of line with usage.

Use the app or Octopus support channels and be specific. Include the date you switched, the tariff you expected, meter photos if readings are disputed, and screenshots of any missing smart data. Clear evidence usually gets a faster answer than a general complaint that the account looks wrong.

If the first month has gone smoothly and you are happy with the tariff, you can keep using the site to compare Octopus options and check whether the referral-code route was applied as expected.
