01 / Before you switch
Is it worth switching to Octopus Energy?
It can be, if the tariff suits your usage and the total cost compares well with your current deal. Octopus offers standard fixed and variable tariffs alongside options for EV charging, electric heating and homes that can move electricity use to cheaper times. A £50 referral reward is a useful extra, but it should come after the tariff comparison.
Bring a recent bill or your online account details. Note your annual electricity and gas usage in kWh, unit rates, daily standing charges, tariff end date and any exit fee for each fuel. Use the same annual usage and payment method for every quote.
A lower Direct Debit does not prove a cheaper tariff
A monthly payment is money paid into your energy account. Your actual charges depend on energy used, rates and standing charges. A quote based on an unrealistically low usage estimate can look attractive while leaving you with a balance to pay later.
Compare the estimated annual cost and the assumptions behind it. On a fixed tariff, the rates are fixed for the stated term; the amount you spend can still change when your usage changes.
Check two sets of exit terms: what it costs to leave your existing tariff, and what it could cost to leave the Octopus tariff you choose. Octopus confirms that some fixed tariffs have exit fees; Flexible Octopus has none. Read Octopus’s current exit-fee explanation.
If you are within the final 49 days of a domestic fixed tariff, you can normally switch without an early-exit fee. Confirm the end date before choosing an immediate transfer. Citizens Advice explains the switching window.
02 / The practical walkthrough
How to switch to Octopus Energy
01
Open the referral link
Start with share.octopus.energy/fun-puma-157 if you want to use our referral. Check the offer displayed by Octopus before continuing. Your quote, contract and payments are handled on Octopus’s website; there is no signup form on this site.
02
Get a quote using your actual usage
Enter your postcode, choose the correct address and select the fuels you want to move. Use annual kWh figures if you have them. For Economy 7 or another multi-rate meter, compare the relevant day and night rates using your own split.
03
Choose the tariff and start date
Check the rates, standing charges, term, exit fees and estimated yearly cost. If you want a smart tariff, confirm its eligibility and joining route first. Joining Octopus and activating a specialist tariff can be separate steps.
04
Complete signup with Octopus
Provide the requested account and payment details and save the confirmation. Check the supply address, fuels, tariff and agreed start date. Octopus handles the transfer with your old supplier; you do not normally need to cancel your energy account yourself.
05
Record the handover readings
Follow Octopus’s request for opening readings. Take dated photos showing the meter readings and serial numbers, including both registers on a multi-rate meter. Keep them until your old final bill and new opening bill agree.
06
Finish the billing checks
Check your old supplier’s closing readings against Octopus’s opening readings. Settle or query the final bill and check any credit refund. Then look for your referral reward after the qualifying supply and payment conditions have been met.
The signup steps and usual transfer time are supported by Octopus’s switching FAQ. The exact screens and options can change.
03 / Four different milestones
How long does it take to switch to Octopus Energy?
Octopus says signup should take no more than about five minutes and it usually completes the supply transfer within three working days. A final bill and referral credit arrive separately. Use your confirmed start date rather than assuming everything happens at once.
| Milestone | What to expect | Your check |
|---|---|---|
| Online application | A few minutes with your details ready | Correct address, fuels and tariff |
| Supply transfer | Usually three working days, according to Octopus | Confirmed start date; a later date can be requested |
| Old supplier’s final bill | Octopus says usually four to six weeks | Matching readings and any refund due |
| Referral credit | After supply starts and the first successful monthly Direct Debit; typically around four weeks from joining | Reward entry in your balance history |
Ofgem’s domestic switching standard is five working days, subject to the applicable rules and your requested date. Its current guidance specifies £40 compensation for a qualifying delay. That is separate from the £50 referral reward. See Ofgem’s switching compensation guide.
Can I change my mind?
You have a 14-day cooling-off period. A fast transfer can happen before that period ends, so contact Octopus promptly if you want to cancel. Ask it to confirm what happens next if supply has already started; energy you use still needs to be paid for. Ofgem explains your cancellation rights.
04 / The £50 offer
Get £50 credit when you switch through our referral
An eligible domestic referral gives the new customer £50 towards their energy account and gives the referrer £50 too. The £100 sometimes mentioned is the combined reward shared between two people.
For the usual Direct Debit route, Octopus applies the reward after it is supplying your home and the first monthly Direct Debit has been successfully taken. It describes the whole process as typically around four weeks from joining, with delays possible. It is account credit, not an instant £50 cash payment for clicking a link.
Your referral code: fun-puma-157
Use the full link to start your quote and check the live offer. A tariff change on an existing account or moving house is not automatically a new qualifying switch.
If you forgot a referral after joining directly on Octopus’s website, its published guidance says to contact it with the code. Joining through a comparison site is a different route and normally cannot be combined with friends-and-family referral credit. Check the official referral rules.
For missing credit, first check supply has started, the payment succeeded and the reward is absent from your balance history. Ask Octopus to investigate rather than submitting a second application. See our full referral credit and eligibility guide.
05 / Compare the whole cost
Will switching actually save you money?
For a simple single-rate comparison, calculate electricity kWh × electricity unit rate, add gas kWh × gas unit rate, then add 365 days of standing charges for each fuel. Convert pence to pounds. Use rates on the same VAT basis. For time-of-use tariffs, cost each usage band separately.
A worked first-year comparison
The figures below are invented examples to demonstrate the calculation. They are not current Octopus prices, a quote or a prediction.
| Same household and usage | Stay | Switch |
|---|---|---|
| Illustrative annual energy cost | £1,650 | £1,600 |
| Old tariff exit fees | £0 | £100 total |
| Eligible one-off referral credit | £0 | −£50 |
| First-year comparison total | £1,650 | £1,650 |
Here the £50 tariff saving plus £50 credit only offsets the £100 exit fees. With no exit fees, the switch would be £100 ahead over the same year. From year two, the one-off reward is gone; compare the tariffs available then.
The low-use household check
A standing charge that is 10p a day lower saves £36.50 a year for one fuel. But if its unit rate is 2p/kWh higher, that extra cost cancels the saving at 1,825 kWh a year: £36.50 ÷ £0.02. Below that usage the lower standing charge wins in this simplified example; above it the lower unit rate wins. Compare both, rather than choosing by one headline rate.
06 / Find the right fit
Which Octopus tariff should you switch to?
| Your priority | Options to investigate | Main check |
|---|---|---|
| Simple rates or price certainty | Flexible Octopus or a current fixed tariff | Annual cost, end date and exit fees |
| Charging an EV at home | Go or Intelligent Octopus Go | Device eligibility, smart-meter connection and daytime cost |
| Moving electricity use away from expensive periods | Agile Octopus | Half-hourly prices and your ability to tolerate spikes |
| Accepting daily wholesale price changes | Octopus Tracker | Prices can rise as well as fall |
| Heat pump or eligible electric heating | Cosy Octopus | Heating schedule, cheap periods and peak rate |
| Solar panels and export | Outgoing or a suitable Flux option | Import/export compatibility and separate export setup |
These are routes to compare, not personalised recommendations. A cheap overnight rate can be outweighed by expensive daytime usage. Agile and Tracker expose you to wholesale price movements; do not assume either will always beat a standard tariff.
Use our Octopus tariff comparison checklist for the eligibility questions and a time-of-use calculation. Check the official smart tariff pages before committing.
07 / Leaving your current supplier
Switching from British Gas, EDF or OVO to Octopus
The core process is the same: compare the quote, submit your application to Octopus and follow the meter-reading request. Your current tariff and account position matter more than the supplier name.
How to switch from British Gas to Octopus
Find your tariff end date and exit fees in your British Gas account. Use your annual kWh usage for the Octopus quote. If you benefit from time-specific discounts or rewards, include their realistic value in your comparison. Keep a record of unresolved billing or meter issues so they can be followed up.
How to switch from EDF to Octopus
Check which fuels you want to move and whether each is fixed. Keep screenshots of EDF’s rates, contract end date and balance. Compare the Octopus offer over the same period and keep both suppliers’ bills until the handover readings match.
Can I switch from OVO to Octopus Energy?
Yes, subject to the usual account and switching checks. Review your current OVO contract, including any EV charging add-on or reward you use. Compare the combined cost of household electricity and charging, and check the date any old add-on ends.
For all three suppliers, an unpaid bill or incorrect meter record can delay the move. An existing smart-meter fault is also worth raising before switching: changing who bills you does not guarantee that a communications problem will immediately disappear.
08 / Meters, bills and exceptions
What happens to your meter and old account?
Will my energy be cut off?
A normal supplier switch does not interrupt your gas or electricity and does not require an engineer visit. You keep the same supply infrastructure. Octopus confirms this on its quote page.
Do I need a smart meter?
You can switch on standard tariffs without one. Specialist smart tariffs have their own requirements. Octopus says it can connect to SMETS2 and some SMETS1 meters, but may still ask for opening readings. If readings are missing, submit them manually and ask Octopus to investigate. Read its smart-meter guidance.
Should I cancel my old Direct Debit?
Keep it in place while your old supplier settles the account, unless it tells you otherwise. A payment to each supplier around the handover is not, by itself, evidence that you paid twice for the same energy. Compare the billing dates, meter readings and account credits. Octopus explains the Direct Debit handover.
Your old balance is settled by the old supplier; it does not simply move into your Octopus account. Octopus says its first Direct Debit is normally taken when supply starts. Check the payment schedule so an opening payment and old final bill do not catch you unprepared.
Can I switch with debt or a prepayment meter?
Octopus supports traditional and smart prepayment meters; contact it to arrange the move. Referral payment arrangements can differ from the standard Direct Debit route.
For a credit meter, the date an unpaid bill was sent matters. Citizens Advice says a bill sent more than 28 days ago can block switching, with different treatment for some disputed bills. For prepayment, debt-transfer rules generally allow up to £500 per fuel, subject to the process. Check the debt rules before applying.
Renting, moving home or exporting solar?
If you pay the supplier directly, you can generally choose your energy supplier; check your tenancy obligations. If the landlord pays or you are on a communal heat network, the position differs. On a move, photograph readings and register responsibility with the existing supplier before arranging a transfer.
Moving your imported electricity does not automatically activate solar export payments. Confirm the export application, documentation, tariff compatibility and export start date separately. Octopus’s export guide sets out its joining process.
09 / If something goes wrong
What to do if your Octopus switch gets stuck
| Problem | Useful next step |
|---|---|
| Old supplier objects | Ask for the exact reason, resolve the bill or record issue, then ask Octopus whether it needs to restart the transfer. |
| Wrong address or meter | Send the supplier the correct supply address and dated photos of your meter serial number. Ask it to investigate before proceeding. |
| Smart readings missing | Provide manual readings and ask whether the meter is connected. Check specialist tariff activation separately. |
| Final bill appears wrong | Compare closing and opening readings, dates, fees and payments. Raise the specific discrepancy with the supplier responsible. |
| £50 has not appeared | Check referral attribution, active supply and successful payment; ask Octopus to trace the reward. |
For supply or account help, use Octopus’s official contact page: hello@octopus.energy or 0808 164 1088. Normal phone hours are Monday–Thursday 9am–5pm and Friday 9am–4pm. This independent site cannot access your account.
What do customer discussions add?
Two Reddit discussions reviewed for this guide include positive accounts of switching and service, alongside complaints about support, meter communications and referral tracking. These are self-selected anecdotes, not a representative customer survey. Their practical lesson is to keep readings and confirmations, and check tariff activation rather than assuming the transfer fixes every existing issue.

10 / Quick answers
Switch to Octopus Energy: FAQs
Get a quote for your address, compare the tariff, complete signup with Octopus and provide opening readings when asked. This guide covers domestic switching in Great Britain; do not apply US switching rules or assume the same market arrangements in Northern Ireland.
Octopus currently provides a public quote and signup route. Availability for your address, fuels and meter is confirmed in the quote journey.
The quote form offers an electricity-only option. Make sure the application matches the fuels you intend to transfer. Check the displayed referral offer for your circumstances rather than assuming a reward per fuel.
No. The best-priced deal depends on your postcode, usage, payment method, current contract and available tariffs. Compare like-for-like annual costs and any fees; do not treat the £50 reward as proof of ongoing savings.
Its domestic terms permit checks with credit reference and fraud prevention agencies. If this affects your decision, ask Octopus about the check used for your application and payment arrangement before submitting it.
A normal tariff change is not a new-customer referral switch. Octopus also says a customer who has already received referral credit does not receive another reward just for moving house. Existing customers can refer eligible new customers under the applicable scheme.
