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.

Who BarbicanPower may suit

Best fit for small to mid-sized non-domestic customers, microbusinesses, and businesses seeking renewable electricity or generator/partner-network services. Ofgem documents show the licence is restricted to non-domestic premises and capped at 10 MPANs, indicating a narrow B2B focus.

Trading name and licence-holder notes

The customer-facing brand is BarbicanPower, while the legal entity is Barbican Power Limited. Ofgem records and Companies House identify the legal company behind the brand; no separate parent trading brand was clearly evidenced in the sources reviewed.

Switching from BarbicanPower to a fixed business contract

UK businesses can switch electricity supply away from BarbicanPower 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 BarbicanPower. 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. BarbicanPower 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. BarbicanPower 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.

Does BarbicanPower publish out-of-contract rates?+

BarbicanPower does not appear to publish a standard deemed or out-of-contract rate online. Business customers should request a written renewal quote in advance of their contract end date and compare it against live market prices.

Can I switch away from BarbicanPower?+

In most cases, businesses can switch electricity supply away from BarbicanPower 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 BarbicanPower?+

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 BarbicanPower a UK-licensed supplier?+

Yes. BarbicanPower is on the Ofgem non-domestic licensee register for 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.
