Not publicly published / quote required

If you are on deemed, default, rollover, variable, or Out-of-contract rates, ask for a written renewal quote and compare it against live market prices before agreeing a new contract.

Where your p/kWh actually goes

Indicative split for a UK I&C electricity bill in 2026, sourced from Cornwall Insight's non-commodity cost research. Your meter, region and contract type shift the exact mix, but the four components are always present.

Wholesale energy, 38%Gas or power bought on the wholesale market. The figure most coverage focuses on.
Non-commodity costs, 53%Network charges (DUoS, TNUoS), policy levies (RO, FiT, CfD, Capacity Market), CCL and balancing costs.
Supplier margin, 6%What the supplier earns. Always priced into the unit rate.
Broker margin, 3%What we earn for tendering and managing the contract. Shown separately on every Purely Energy quote.

Who RWE Supply & Trading GmbH may suit

Strong fit for large industrial and commercial energy users seeking tailored wholesale gas, power and risk-management solutions rather than a standard published SME tariff. Best suited to sophisticated B2B buyers that can negotiate bespoke supply terms.

Trading name and licence-holder notes

The licence holder trades under the RWE Supply & Trading brand, and RWE’s site also references UK trading floors in Swindon and London. A separate RWE-linked brand, Edgware Energy Limited, is listed among European sites on the company page, but no evidence was found that it is the customer-facing UK business brand for this licence holder.

Switching from RWE Supply & Trading GmbH to a fixed business contract

UK businesses can switch gas supply away from RWE Supply & Trading GmbH once their fixed contract ends, or after resolving any open objection or termination-window issue. The process is the same for every supplier on the non-domestic market, but a few checks done in the right order make the transfer materially faster.

1. Find your contract end date. It's on your last renewal letter or the most recent bill from RWE Supply & Trading GmbH. Most non-domestic contracts have a 1 to 6 month termination window before that date, outside of which you may auto-roll onto a new fixed term.
2. Get your MPRN ready. The 21-digit MPAN (electricity) and 6 to 10-digit MPRN (gas) uniquely identify each meter and are needed for any competing quote. Both appear on your bill.
3. Compare against the live market. RWE Supply & Trading GmbH doesn't publish standard out-of-contract rates, so request a written renewal quote first and benchmark it against live market prices before agreeing anything. Purely Energy can run your meters against the wider UK panel and come back with the cheapest fixed offers.
4. Settle the final bill and clear any objections. RWE Supply & Trading GmbH will issue a final bill within 6 weeks of supply transferring. If a balance is outstanding, they can object to the switch under industry rules, so clear it before the transfer date to avoid a hold.
5. Sign the new contract. Once the new supplier has your MPAN/MPRN and signed contract, the transfer typically completes within 4 to 8 weeks. There is no break in supply, you simply receive your first bill from the new supplier.

What are out-of-contract business energy rates?+
