Fast answer: what most people should know about So Armadillo 12m

So Armadillo 12m 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.

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 So Energy tariffs before drilling into the regional tables.
