Fast answer: what most people should know about Extended Fixed 18 December 2025

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 £50.00 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 OVO energy tariffs before drilling into the regional tables.
