Energy & renewables finance
Fund equipment and installers before customers pay.
Bridge equipment, labour and commissioning costs while completed installations wait for payment.

On a £50,000 invoice on 30-day terms: £45,000 advanced at 90%, £4,000 when your customer pays, a fee of about £1,000.

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.

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.

Common questions
Questions about energy and renewables funding.
Which funding route usually fits energy and renewables businesses?
Usually invoice finance, with trade finance where equipment must be paid for before installation. Funding is strongest once an installation is commissioned and signed off, not while it awaits testing or connection.
What evidence helps an energy and renewables funding assessment?
Contracts, purchase orders, commissioning certificates, handover sign-off, project margin and debtor ledger. Invoices raised after commissioning, backed by signed handover certificates and grid-connection or test records, are the cleanest part of an energy ledger.
What can limit or slow energy and renewables funding?
Uncommissioned work, connection delays, performance guarantees and excessive customer concentration. Contractual retentions, uncertified stage applications and payments that depend on grants or export tariffs are hard to fund and usually sit outside availability.

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.
