What qualifies for the green fast-track

Sustainability-led business projects receive priority underwriting and a 48-hour decision turnaround. The standard of credit assessment is the same as for any of our business loans; only the speed differs.

The principle is simple: we want to deploy more capital, faster, into the businesses driving the energy transition, decarbonisation, circular economy, and regenerative practice. The fast-track removes a key friction in that deployment.

Who this loan is for

  • Renewable energy installers and developers — solar, wind, heat pumps, biomass
  • Energy-efficiency contractors retrofitting commercial or residential buildings
  • Sustainable agriculture, regenerative farming, and food-system businesses
  • Clean transport businesses — EV infrastructure, fleet electrification, alternative fuels
  • Circular-economy businesses — repair, reuse, remanufacturing, recycling
  • Sustainable construction and modular building businesses
  • Carbon project developers and ESG-aligned infrastructure operators
We needed £4.5M to scale our solar installation business across three regions. ASAF's green-loan fast-track approved us in 48 hours. Best banking decision we have made. — Verde Renewables Ltd · green business loan, £4.5M

How the fast-track operates

The fast-track is not a separate underwriting standard — it is a separate processing path. Green-loan applications are routed to a dedicated team that reviews the file as a priority, with credit committee meetings convened within 48 hours of complete application receipt.

To qualify, your application must demonstrate that the loan's primary purpose contributes to environmental sustainability. We assess this against a transparent eligibility framework that includes — but is not limited to — UK Green Taxonomy alignment, ICMA Green Loan Principles, and our own internal ESG criteria.

Once approved, drawdown is the same as any of our business loans. Funds can be released within hours of acceptance, particularly for time-sensitive opportunities (project bid timelines, equipment ordering deadlines, contract deposits).

Frequently asked

The honest answers,
before you ask.

Beyond standard business loan documentation (financials, ID, KYC), we ask for a brief description of the project, its environmental impact (qualitatively or quantitatively where measurable), and any third-party certifications or assessments (e.g. EPC ratings, ISO 14001, B-Corp, BREEAM).
No. The standard of credit underwriting is identical to any other business loan. The fast-track relates only to the speed of processing — not to leniency on financial diligence. A green project must still demonstrate the ability to repay the loan.
We can still fast-track if the green component is the primary driver. For projects that are 50% or more green by capital deployment, we apply the fast-track to the entire facility. For lower percentages, we apply it to the green tranche specifically.
If you are a contractor delivering green retrofits to your customers, we can fund your business operations (working capital, equipment, vehicle fleet) as a green business loan. For homeowners directly funding their own retrofit, our Personal Home Improvement loan offers the same 48-hour green fast-track.
We ask for an annual update on the project's environmental impact — typically a paragraph or two describing what was deployed, what it has displaced, and any measurable outcomes (CO2 avoided, kWh generated, tonnes diverted from landfill, etc.). This goes into our published annual sustainability report.
