Reported terms and dispute process
- Standard payment terms
Renewable Energy Systems Ltd (“RES”) has standard payment terms of 30 days. If a supplier requests that RES complies with their standard terms and conditions and these contain payment terms which are different to 30 days, then, subject to Director approval, RES will adopt the supplier’s terms. There is no maximum contractual payment period within RES’s General Terms & Conditions of Purchase.
- Other payment-term information
Renewable Energy Systems Limited has undertaken a system migration during the six month period to 30 April 2026, causing temporary delays in the time taken to pay suppliers during this time.
RES operates three payment runs each month and this can result in some invoices being paid later than the agreed payment period. Many of the 87% not paid within the agreed payment period is due to invoices that stated they were due for payment on presentation and as this is not practical, we do not believe it is a helpful statistic. If we were only to include those that were not paid within 30 days of receipt, this statistic would fall to 53%. - Dispute resolution process
If at any time a dispute or difference arises between RES and the supplier in relation to or in connection with an accepted Purchase Order, both parties will aim to resolve the dispute through negotiation. If such dispute or difference cannot be resolved through negotiation, then either party may require the other party to give them notice in writing of the existence of such dispute or difference and at the request of either party, the same shall be referred to an Alternative Dispute Resolution (ADR) procedure as recommended to the parties.

Identity methods differ by source. DfE links use source-supplied company numbers. Ofsted and Scottish care links are unique exact name-and-postcode candidates. HSE links require one unique exact Companies House organisation name. Verify candidate associations independently.

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.
08 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.
09 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.
10 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.
11 Public procurement
Find a Tender links
No exact GB-COH link in this snapshot
Find a Tender did not explicitly identify this Companies House number in a procurement party. BritDB did not attempt a name-only match.
These links use only the GB-COH identifier supplied in the procurement record. A company may have other public-sector work that is absent, older, below publication thresholds or published without a Companies House identifier.
12 Environmental register
Environment Agency waste registrations
No exact company-number registration linked
The licensed Environment Agency subset did not contain this exact Companies House number. BritDB did not attempt a name-only match.
This is a privacy-reduced, exact-company subset. The full official register also includes sole traders and applicants without a matching Companies House number. Check the current Environment Agency register before relying on registration status.
