Fast answer: what most people should know about Co-op 18M Fixed October 2026 v1

Co-op 18M Fixed October 2026 v1 is best treated as a single tariff family page because the same tariff name can appear across multiple service types, payment methods, Economy 7 settings and 14 PES regions. The best version for you depends on your postcode, meter setup and how you actually pay for energy.

What our price data says: Co-op 18M Fixed October 2026 v1 is closed to new customers: a fixed tariff for 18 months, exit fee £75 per fuel. Against the Ofgem cap for 1 October to 31 December 2026 its electricity unit rate is below the cap in 12 of 14 regions and above it in 2 (from −1.26p/kWh to +0.24p/kWh) and its standing charge is below the cap in every region (by 0.39 to 1.53p a day). In London the unit rate is 25.34p against a 26.60p cap and the standing charge 41.39p a day against 42.92p; a home at Ofgem typical use (2,500 kWh of electricity and 9,500 kWh of gas a year, Direct Debit) could pay about £1,689 a year on this tariff against £1,706 at the cap (−£17), standing charges included. See every region

Editor's rule of thumb: compare only like-for-like. If you are on Direct Debit, compare Direct Debit. If you need Economy 7, compare Economy 7. If you want dual fuel, do not compare it against an electricity-only row and assume the result is equivalent.

Costs, exclusions and common pitfalls to check

Most mistakes happen when the wrong regional or payment-type version of the tariff is compared. Use these checks before switching.

1) Region matters

There are separate regional records because energy pricing differs across PES areas. Do not assume a headline price applies nationally.

2) Payment method affects price

Direct Debit, bill payment and prepayment variants can differ materially. Compare like-for-like only.

3) Economy 7 is usage-sensitive

Economy 7 can help if enough usage is overnight, but can cost more overall if most use is daytime.

4) Fuel bundle changes the comparison

Dual fuel should not be compared directly with electricity-only rows unless you normalise the usage assumptions.

5) Exit fees reduce flexibility

Records shown for this tariff include exit fees of up to £75.00 per fuel. Check the exact regional row before switching.

6) Postcode still beats region-only estimates

Region is useful for guidance, but a postcode-based quote is more precise because it reflects the actual tariff availability and pricing for your home.

Helpful shortcut: if you are not sure this is the right product family, compare all Co-op Energy tariffs before drilling into the regional tables.
