Standard tariffs
Compare estimated annual total on the same usage.
HOUSEHOLD ENERGY
Compare electricity tariffs around how you use energy
A low headline unit rate can be offset by standing charges or unsuitable time windows. Compare annual cost using your own consumption and payment method.
Decision routes
Start with the outcome, not the advert
EV tariffs
Model daytime rates and vehicle demand as well as the off-peak window.
Smart tariffs
Automation and tolerance for variable prices become part of suitability.

Unit and standing ratesModel both parts of the bill for the full term.
Fixed or variableCompare certainty, exit fees and what happens after the term.
Time-of-use fitEVs, batteries and heat pumps can change the useful tariff shape.

Frequently asked questions
General UK guidance. Product, property, tariff and policy details still need individual verification.
What information do I need to compare tariffs?+
Annual electricity use, postcode, payment method and current tariff details are a strong starting point.
Why include the standing charge?+
It is paid daily regardless of consumption and can materially change the annual total.
Is an EV tariff always cheaper for an EV owner?+
No. The vehicle may benefit overnight while the rest of the home faces different rates. Model the whole bill.
Should I use estimated or actual consumption?+
Actual recent consumption is normally more useful, adjusted for known changes such as a new EV or heating system.
