Reported terms and dispute process
  1. Standard payment terms

    5days for wholesale power/gas invoice settlement
    10days for power purchase invoice settlement
    14days for certain industry costs settlement
    30days for operating and capital expenditure purchases

  2. Other payment-term information

    "SmartestEnergy Ltd operates a daily payment run and captures all undisputed invoices due for payment in 3+ days time.
    Payments are generally made by BACS and suppliers receive payment within 3 days from the day of payment approval.
    When any invoice becomes overdue (following a dispute resolution or for operational reasons) and it is approved for payment, it will be settled via CHAPS to reduce number of overdue days.
    Some key suppliers have a mandatory payment method of Direct Debit. These suppliers are always paid per contractual payment terms, whether invoices are in dispute or not.
    Our average agreed payment terms of 15 days with an actual of 15 days clearly demonstrates SmartestEnergy Ltd pays its suppliers on a timely basis."

  3. Dispute resolution process

    Invoices related to wholesale power/gas settlement, power purchase, operating and capital expenditure
    Invoices are matched to a purchase order/billing document on receipt.
    Should the invoice and order/billing document not match, the AP Accounts Assistant will liaise with the relevant settlement team to confirm the correct information and work with the supplier to enable the correct payment to be made.
    In the event the AP Accounts Assistant is not able to agree with the supplier, the dispute is escalated to a Customer Service Executive.
    Should the payment query still not be resolved, it will be referred to our VP Finance for further consideration.
    Upon resolution the invoice is placed on the next available payment run.
    Remittance advices are sent via e-mail to each supplier. This is in order for the supplier to match the payment received against the same invoices as SmartestEnergy Ltd has matched to and avoid disputes about mis-matching of payments.
    Invoices related to Electricity and Gas industry charges
    Per industry requirement all Electricity and Gas industry settlement costs must be settled regardless whether SmartestEnergy disagrees with invoiced values at the time invoice falls due for payment.
    Several such suppliers are paid via a mandatory Direct Debit payment method that operates on our corporate bank account.
    There is a separate formal industry cost dispute resolution process in place, which is taken care of by the Supplier Management team. Any amounts in dispute that are resolved, are settled as part of the following invoicing/credit note cycle. These disputes therefore do not affect payment terms.
    In an event of invoice payment query our Accounts Payable team can assist by contacting them on the following email or phone:
    back-office@smartestenergy.com
    Phone 01473 234946

The supplier link is exact, but the award remains buyer-published procurement data. BritDB requires the GB-COH identifier supplied in the Contracts Finder OCDS release and does not infer suppliers from similar names.

Exact owner-name matches

7 records

This is an exact normalised company-name match, not a registrar-confirmed ownership link. Another legal entity can have the same or a very similar name. UKIPO data is a historical 2018 snapshot; verify the owner and current status before relying on it.

09 Charity register

Charity Commission links

Snapshot 29 September 2026

No exact company-number link in this snapshot

The Charity Commission extract did not explicitly associate this Companies House number with a charity. BritDB does not use a name-only match to fill the gap.

i

This company-level check covers the Charity Commission for England and Wales. Links are accepted only when the official extract supplies this exact company registration number. Scottish charities now have separate OSCR profiles, but OSCR’s bulk fields do not provide a Companies House number, so BritDB does not infer a company link.

The CCNI source number did not resolve uniquely to this Companies House record. BritDB did not use a name or address match.

The imported UK Sanctions List did not supply this Companies House number as a UK-linked business identifier. BritDB did not attempt a name-only match.
