National Grid Electricity Distribution do have different types of standard contracts depending on the product, service or works but the standard payment terms for the majority of our contracts is Net Monthly - this means payment will be due on the last day of the month following the one in which NGED receives a correctly rendered invoice.
This also applies to purchase orders raised with no formal contract in place. - Dispute resolution process
Invoice disputes and/or general enquiries regarding the status of an invoice would be dealt with by Accounts Payable initially. If the enquiry could not be resolved it would be escalated to either the person responsible for raising the order or the appropriate Business Management. For specific contractual disputes, the relevant member of the procurement team would be contacted to resolve as quickly as possible.
Dispute resolution forms part of our Standard Terms & Conditions. Please refer to

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.
11 Charity register
Charity Commission links
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.
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.
12 Northern Ireland charity register
CCNI exact company links
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.
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.
13 Sanctions screening
UK Sanctions List
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.
