How is Flex different from a normal fixed contract?

A fixed contract sets the entire price on day one and never moves. Flex splits your forecast volume into tranches and executes each tranche separately against rules you agree with us. Some tranches might be triggered by price, some by date, some by an event such as a sustained dip in the curve. The blended weighted average is your effective unit rate.

How small can my consumption be to qualify?

200,000 kWh (200 MWh) per year on either gas or electricity. Below that the cost of running a managed strategy and the fixed overhead of supplier flex agreements outweighs the saving. We will tell you honestly during the strategy review if Flex is not the right product for your scale.

Who runs the trading desk?

Purely Energy. The desk is staffed by named traders who hold the supplier relationships, monitor the curves, and execute trades on your behalf within the strategy you have approved. You meet your trader during onboarding and they own the relationship.

How are trades priced and validated?

Each trade is struck at the supplier's quote for that volume and tenor, then validated against our independent licensed wholesale forward-curve data feed. The trade ticket records both prices so you can audit independence.

Can I see every trade?

Yes. Every trade is in the monthly performance pack with date, volume, tenor, strike price, validation price, and the running weighted average. You also see the live volume-purchased progress bar against your forecast.

How is the price quoted?

Every Purely Energy quote breaks the unit price into its four components: wholesale energy, non-commodity costs, the supplier margin, and the Purely margin. You see all four before you sign. There is no all-in price hiding a broker uplift, and no commission paid by the supplier you do not know about.

Do you stay involved after the contract is signed?

Yes. Full contract support is included for every customer for the life of the agreement. That covers bill validation, query handling, supplier escalations, change-of-tenancy events, and renewal-timing recommendations. We are not a one-and-done broker.

Does Flex handle non-commodity costs too?

Wholesale energy is the part we trade. Non-commodity costs are typically passed through at actual on a flex contract because they are not really tradeable, but we forecast them inside the same monthly report so your total p/kWh number is always visible.

Purely Flex is our managed flexible-purchasing product for businesses consuming 200,000 kWh a year or more on gas or electricity (200 MWh, roughly £25k of annual spend at current rates).

Flex is the right product when your consumption is large enough that a 5 to 10 percent change in the unit rate is material at the bottom line, and when the business has the appetite to manage timing rather than write the cheque on day one. The floor is 200,000 kWh per year on either fuel (the same volume as roughly 70 average UK households). Most of our flex clients sit in the 0.2 to 50 GWh band, with the largest above 100 GWh. They typically run a basket of tranches across the forward curve, with rules for when we pull the trigger.

The strategy is yours, the execution is ours. We agree volume per tranche, trigger price, fallback dates, maximum exposure to spot, and any constraints around cash or carbon. The trading desk monitors the wholesale market every working day, executes each tranche when the rules allow, and locks the price with the underlying supplier. You see every trade, the running weighted average, and the comparison to a benchmark you choose (day-ahead, season-ahead, or a custom index).

Flex pairs well with Fixed for a 'base plus overlay' strategy: fix 60 to 80 percent of expected volume for budget certainty, run the remainder on flex to capture market dips. It also pairs with Purely Insights so the consumption forecast feeding into your tranche schedule is always current, not last year's annual figure.
