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 Marble Power Limited may suit
Best suited to UK businesses seeking a quote-led electricity and gas supplier with fixed or flexible contracting options rather than a publicly posted tariff. The available material suggests fit for small to large non-domestic sites, including customers wanting account-managed service and bespoke pricing.
Trading name and licence-holder notes
The supplier appears to trade under Marble Power Limited, which is also the legal entity and licence holder. Ofgem lists Marble Power Ltd under electricity and gas non-domestic supply licences, and the website uses Marble Power Limited branding consistently.
Switching from Marble Power Limited to a fixed business contract
UK businesses can switch gas and electricity supply away from Marble Power Limited 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 Marble Power Limited. 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 MPAN and 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. Marble Power Limited 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. Marble Power Limited 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.

Can I switch away from Marble Power Limited?+
In most cases, businesses can switch gas and electricity supply away from Marble Power Limited at the end of a fixed-term contract or after resolving any objections, debt, termination-window, or meter-data issues. The safest route is to check your contract terms, final bill position, and renewal dates before starting a transfer.
How long does it take to switch from Marble Power Limited?+
Once a new supplier has the meter point details (MPAN/MPRN) and a signed contract, a non-domestic switch typically completes within 4 to 8 weeks. Supply does not break: the new supplier takes over billing on the transfer date.
Is Marble Power Limited a UK-licensed supplier?+
Yes. Marble Power Limited is on the Ofgem non-domestic licensee register for both gas and electricity. Ofgem maintains the official register at ofgem.gov.uk.
What are out-of-contract business energy rates?+
Out-of-contract rates are the prices a business pays when no fixed-term contract is in place with its supplier. They can be materially higher than negotiated contract rates, so businesses should check their contract end date and renewal window before they expire.
