Tariff comparison

Your load shape changes what cheap means.

Price fixed, flexible and imbalance-exposed structures against the half-hours you actually consumed. Network and policy charges are carried too, from the comparison’s own rate register, rather than comparing unit rates alone.

Fixed → flexible → full imbalance exposure, on the same half-hours

The tariff comparison in Simplest Energy: fixed at 24.94 p per kWh all-in, flexible at 26.38 and full imbalance exposure at 13.49, each with its ex-VAT total, above a bar chart of where each modelled cost comes from
One real month of half-hours, priced three ways: 24.94 p/kWh fixed, 26.38 flexible, 13.49 fully exposed. The screen says it itself, above the cards: the lowest figure is an exposure view, not a supplier offer. The bars carry commodity alone because this demonstration estate has nothing in that rate register yet.

The three structures

One month of half-hours, priced three ways.

The same consumption, the same period, three ways of buying it. The difference between them is not the unit rate, it is who carries the risk.

Fixed

24.94

p/kWh all-in

You carry no price risk for the term, and you pay for that certainty in the rate.

A supplier offer.

Flexible

26.38

p/kWh all-in

Bought in tranches across the term, so the average lands wherever the market went.

A supplier offer.

Full imbalance exposure

13.49

p/kWh all-in

Every half-hour settled at the imbalance price. The cheapest modelled figure here, and the one carrying all of the risk.

Not a supplier offer. An exposure view, and the floor of what the month could have cost.

From one real month on a demonstration estate, not a customer. The lowest of the three is an exposure view rather than something anybody can buy, which the product says on the screen above the cards as well as here.

Nothing is a black box.

The rest of the market

Your own numbers, and everyone else's.

A renewal is decided against the market as well as against your own load. Supplier market share and generation mix sit alongside the comparison, from published industry data rather than from anybody's estimate.

  • Supplier market share by quarter and by reporting group
  • Generation mix, from the published record of what is on the system
  • Read beside your own comparison rather than on a separate service
  • Published sources throughout, so a figure can be checked rather than trusted

A quote and a year of your own half-hours is the whole input.

We will price it against your own half-hours on the call, and show you every rate behind the answer.
