What the trading desk sees
Screens from a live client account, not a mock-up.
The portfolio on one line
Cost cap, portfolio cost, what the same volume would cost at today's market, and how much of the total volume is hedged, each one shown against the figure it is measured against.
Every month, how much is covered
One tile per delivery month: percentage hedged, hedged volume against forecast, and a hover detail for any month. Here 2026 is fully covered and 2027 is being layered in month by month.
Hedged, in progress, still tradable
Stacked volume by month with the weighted average price you have locked and the estimated close price on the right-hand axis.
See today's wholesale curveWhat a price move would cost
Monthly exposure under five scenarios: the base case and prices 5 and 10 percent either side of it. The lines only fan out where volume is still open.
Volume against budget, per period
Forecast, tradable, fixed, open and unfixed MWh for each month, with the percentage fixed and the budget cost and price it implies.
Why volume tolerance mattersEvery trade, on the record
Date, delivery period, direction, volume, price and total cost for each tranche, with its status. Completed trades and open orders sit on separate tabs.
The number the finance director asks for
Total estimated contract cost, split into what is already hedged and what remains open, updated as each tranche is executed.
What's included
Everything in the contract
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). Instead of fixing the entire volume at one point in the curve, we split your forecast into tranches and execute each one against an agreed strategy: trigger price, calendar window, or risk-managed average. The Purely trading desk runs the platform, makes the recommendations, and reports performance against benchmark every month.

Who it fits
Built for businesses like these
Logistics group, 38 sites, 24 GWh per year
Procurement director wants to capture the 18 percent dip the curve shows in Q3, without committing the whole basket.
60 percent of volume on a 24-month fixed base, 40 percent on flex with trigger prices set 4 percent below the prevailing season-ahead average.
Industrial bakery group, 6 sites, 9 GWh gas
Consumption is seasonal and weather-driven, fixed pricing forced them to over-commit.
Weekly tranche execution against a 7-day rolling consumption forecast from Insights. Cash-out volume on the spot market at month-end.
Cold storage operator, single site, 14 GWh electricity
Margin compression on the underlying business meant a £2/MWh saving was material to FY EBITDA.
Pure flex strategy with a £45/MWh trigger and a hard floor at day-ahead minus £1. Saved £128k against the fixed alternative quoted at the same time.
Questions, answered
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.
Anything else, call 0161 521 3400 and a real person will answer, 8am to 6pm, Monday to Friday.
