Non-commodity costs, 53%Network charges (DUoS, TNUoS), policy levies (RO, FiT, CfD, Capacity Market), CCL and balancing costs.

Who UK Power Reserve Ltd may suit

Business-energy fit appears to be non-domestic electricity supply, but public-facing sales information, tariffs, and contract terms were not found. Based on available official sources, it is best treated as a supplier that may require direct quotation / broker-led engagement rather than a self-serve SME retail supplier.

Trading name and licence-holder notes

The licence holder and trading name appear to align as UK Power Reserve / UK POWER RESERVE LIMITED. However, the public domain currently resolves to a domain-for-sale page rather than an operating supplier website, so there is no clear evidence of a separate consumer-facing brand or group website from the sources reviewed.

Switching from UK Power Reserve Ltd to a fixed business contract

UK businesses can switch electricity supply away from UK Power Reserve Ltd 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 UK Power Reserve Ltd. 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 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. UK Power Reserve Ltd 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. UK Power Reserve Ltd 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.
