Cash-flow cycle #### Where the pressure develops Equipment and labour costs before commissioning sign-off can create a gap between delivery, operating costs and the date customers actually pay. Documents #### What helps assessment Installation contracts, commissioning certificates, invoices, handover sign-off, customer approval evidence help make the first funding discussion specific rather than exploratory. Structure #### What the facility should achieve The structure should match the trading cycle, debtor quality and repayment route rather than simply chase a product label. Sector-specific discussion Bring customer terms, expected funding cycle, supporting evidence and any existing finance arrangements to the call. View funding scenarios Sector detail ### Where funding fits an energy or renewables business. Evidence that matters #### Commissioning and handover sign-off Invoices raised after commissioning, backed by signed handover certificates and grid-connection or test records, are the cleanest part of an energy ledger. What strengthens the case #### Commercial customers on agreed terms Billing businesses, developers and public bodies on agreed terms - rather than consumers or subsidy claims - keeps more of the ledger eligible. What can limit funding #### Retentions, stage claims and subsidy timing Contractual retentions, uncertified stage applications and payments that depend on grants or export tariffs are hard to fund and usually sit outside availability. An illustrative example A commercial solar installer invoices £150,000 a month on commissioning with signed handover certificates, while paying for panels, inverters and installation crews weeks earlier. Illustratively, invoice finance advances up to 90% of each commissioned invoice, with retentions and uncertified stage claims simply excluded from availability rather than blocking the facility. Illustration only - every facility depends on individual assessment and underwriting.

Sector underwriting ### Energy and renewables funding: what the assessment needs to understand. #### Cash-flow pattern Equipment lead times, staged installation and commissioning sign-off #### Evidence to prepare Contracts, purchase orders, commissioning certificates, handover sign-off, project margin and debtor ledger. #### Common blockers Uncommissioned work, connection delays, performance guarantees and excessive customer concentration. Practical funding fit #### Structure follows the point at which value becomes evidenced. Funding is strongest once an installation is commissioned and signed off, not while it awaits testing or connection. Practical context ### Energy invoices depend on commissioning, not just issue date. Energy and renewables businesses often buy panels, inverters, batteries or plant well before a project is installed, tested and handed over. That means the real funding evidence may include supplier orders, installation records, commissioning certificates, test results and customer handover sign-off - not merely a PDF invoice. The review also needs to separate clean trade debt from work in progress, retentions, variations and payments that depend on grid connection, grants or export tariffs. Equipment deposits, specialist installers and long lead times can create pressure before a project is commissioned. A workable facility is built around the portion of the ledger that is completed, accepted and collectable. - Identify commissioning and sign-off requirements contract by contract. - Separate retentions, grants and tariff income from eligible debt. - Show customer concentration and project completion exposure.
