Rule: You may end supply at the moving-out date. Provide a final meter reading and your moving date. Required proof documents: forwarding address for final bill and final meter reading. Applicable law: Consumer Contracts Regulations 2013 for off-premises/online contracts where cooling-off may apply if within 14 days.
Rule: If your tariff has a unilateral price increase that is not allowed by the contract, you can switch supplier or change tariff. Required proof documents: copy of the tariff notice Octopus sent and date of change. Applicable law: Consumer Rights Act 2015 on unfair contract terms.
Rule: Next of kin or executor may close the account by contacting Octopus and giving proof. Required proof documents: death certificate and proof of authority (will or executor papers) or proof of identity of next-of-kin. Applicable law: general consumer protections and account-transfer practice; follow Octopus requests for documents.
Rule: Octopus accepts contract end at the end of the fixed term, switching to another supplier, or within statutory cooling-off. Octopus will not seek charges for energy older than 12 months unless they already attempted recovery or customer obstructed. Required proof documents: depending on case, meter reads, correspondence, or evidence of recovery attempts. Applicable law: Consumer Rights Act 2015 and Consumer Contracts Regulations 2013.
Rule: If your fixed-term tariff ends, you can leave without exit fee if the tariff terms state no exit fee; some 12-month fixed tariffs include an exit fee of £50 per fuel. Required proof documents: end-date confirmation from your Octopus account or final bill. Applicable law: Contract terms consistent with consumer protections under Consumer Rights Act 2015.
Rule: For online or off-premises contracts you have a 14-day cooling-off period under the Consumer Contracts Regulations 2013. If you cancel within 14 days and supply already started you must pay for energy supplied between the start date and the cancellation date. Required proof documents: cancellation notice (email or web record) and any meter readings. Applicable law: Consumer Contracts Regulations 2013 (14-day cooling-off).
Retention offers: public research does not list specific standard retention discounts Octopus guarantees. To request retention, contact Octopus via account message or [email protected] and ask for a retention rate or a renewal fixed-rate offer. Provide your current tariff name and last 3 months of usage to support the request. If Octopus gives an offer, get it in writing (email) before accepting.
Example tariff: Octopus 12M Fixed April 2026 (v3) sample cost for an average household: £1,200 per year. Alternative example tariff on Octopus Tracker v3 sample cost: £1,488 per year. Conservative saving by switching from Octopus Tracker v3 to Octopus 12M Fixed April 2026 (v3) is: £1,488 - £1,200 = £288 per year. If you leave Octopus 12M Fixed April 2026 (v3) with a competitor whose comparable offer is lower, compute the saving as competitor annual price subtracted from £1,200. Specific monthly math example: £100 per month x 12 = £1,200 per year. Identify cheapest live offers using a comparison site or Octopus tariffs and competitor pages such as Good Energy Standard Apr26 for exact competitor pricing in your postcode.
Regulator: Ofgem. Statutes: Consumer Rights Act 2015 and Consumer Contracts Regulations 2013. The Consumer Contracts Regulations 2013 give a 14-day cooling-off right for online and off-premises contracts. The Consumer Rights Act 2015 prevents unfair contract terms and disproportionate cancellation penalties.
Cooling-off: You may cancel within 14 days by notifying Octopus; if supply started you pay for energy consumed between supply start and cancellation. Refunds: Octopus refunds credit balances where refund does not cause the account to fall into debt; they attempt to refund to the latest payment source first and may issue a cheque in certain circumstances. Octopus will not try to recover charges older than 12 months unless they previously attempted recovery or the customer obstructed.
First complain to Octopus via account messaging or [email protected]. If unresolved, contact Citizens Advice or escalate to the Energy Ombudsman. For unfair contract terms or auto-renewal issues, you can raise a complaint with the Competition and Markets Authority. If you paid by card, consider chargeback or Section 75 where applicable.
Provide a final meter reading on your moving-out date or last day of supply. Keep the final bill and the date the account was closed. If you are due a refund, Octopus will attempt to refund to the last payment source and will not issue a refund that causes the account to fall into debt.
You can download usage and billing history from your Octopus account or request copies by contacting [email protected]. Keep evidence of all correspondence and confirmation emails for six months.
If you leave a tariff with an exit fee or a 12-month restriction, note specific tariff rules: Tracker v3 has a 12-month formula commitment and some terms prevent rejoining for 9 months if you leave within 12 months. For rejoining, sign up on Octopus Energy or via a supplier switch.
