Reported terms and dispute process
- Standard payment terms
The payment terms operated by SDC Builders Limited varies depending upon the type of supply and, in some instances, for who our end client is.
Material purchases are paid at the end of the month following the month of invoice.
The standard terms for paying the majority of subcontractors is 49 days from the date of the main contract valuation. There are however some exceptions where certain works done for specific clients are paid on terms of 60 days and 78 days. - Dispute resolution process
Subcontract issues should be addressed to the quantity surveyor responsible for the particular job worked on. They can then discuss any disputes and hopefully resolve the issues before notifying accounts to make a payment.
Material invoices are agreed to details provided by the buying department and should an issue arise in pricing discrepancies then they tend to be dealt with by the accounts team along with the buying department.
If the issue is in respect of the quality or other non pricing matters then it will be an issue for the buying department, site managers, surveyors and supplier to discuss and hopefully resolve any issues.

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.
07 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.
08 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.
09 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.
