Reported terms and dispute process
  1. Standard payment terms

    Standard payment terms

    Sellafield currently employs three different payment terms that can be considered as standard, as described below:

    Net Cash Monthly - Payment is made by the end of the month following the month in which the invoice is dated - this payment term remains in use for contracts / frameworks in place prior to 26/02/2015 – the date upon which the Public Contracts Regulations 2015 came into force. Use of this payment term is diminishing as these legacy contracts / frameworks come to an end.

    30 Days from Invoice Validation - Payment is made no later than a period of 30 days from the date on which Sellafield Ltd has determined that the invoice is valid and undisputed. This payment term generally applies to contracts / frameworks placed from 26/02/2015 onwards.

    21 Days Net - Payment is made within 21 days of the date of the invoice – this is tailored to take account of the payment process under NEC 3 contract terms and conditions

  2. Other payment-term information

    N/A

  3. Dispute resolution process

    Sellafield Limited actively seeks to resolve disputes by discussing them with the relevant supplier(s), typically involving contract management teams from both parties. Where agreement cannot be reached at a working level, the dispute will be discussed between senior representatives of the parties.
    Where it is not possible to reach agreement most contracts will contain a dispute resolution procedure, which details the route for mediation, arbitration and bringing a claim in the courts.

This is a company-submitted statutory disclosure, not a credit rating. BritDB preserves the reporting period and links the report only through the Companies House number supplied by the official service. Percentages describe payments made during that period and may change in later reports.

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.

PSC records are company-filed public-register information. When the exact same displayed individual name occurs at multiple companies, BritDB offers a non-indexed cross-reference page. It is a name match only, not proof that the records describe the same person. Service addresses and partial dates of birth are deliberately omitted.

09 Charity register

Charity Commission links

Snapshot 29 September 2026
CCEW

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.

10 Northern Ireland charity register

CCNI exact company links

Snapshot 29 September 2026
CCNI

No unambiguous company-number link found

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

i

CCNI publishes company numbers without a jurisdiction prefix. BritDB links only when the plausible padded UK and NI candidates resolve to exactly one Companies House company.

11 Sanctions screening

UK Sanctions List

Report 8 October 2026
UKSL

No exact business-registration-number link found

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.

!

No exact link is not sanctions clearance. UK restrictions can apply through ownership or control even where an entity is not separately named. Always use the current official list and obtain appropriate advice for a legally significant decision.
