Why sustainability finance matters now

UK businesses face rising energy costs, new carbon reporting expectations and growing pressure from customers and supply chains to reduce emissions. The UK’s net-zero commitments and evolving regulation mean that investing in energy efficiency or low-carbon technology is often both commercially sensible and strategically important — reducing operating costs and improving access to ESG-aware customers and contracts. For context, government policy continues to prioritise decarbonisation and business support for green investment (see UK Net Zero strategy).

• Cut energy spend and improve margins by investing in efficiency and renewables.
• Open opportunities with customers and public sector tenders that require sustainability credentials.
• Pairing loans with grants or incentives can reduce payback periods and overall project cost.

Let’s explore the types of projects lenders and brokers typically fund — and how Fast Business Loans helps you reach them quickly.

What counts as a sustainability project?

Sustainability projects take many forms. Below are the common categories lenders and specialist brokers fund for UK SMEs.

Energy efficiency & renewables

• Solar PV installations for rooftops and ground-mounted arrays — example: a 50kWp system for a production unit.
• Heat pumps, LED lighting, improved insulation and intelligent building controls.
• Typical outcomes: lower electricity bills, reduced reliance on grid imports, improved EPC ratings.

Low-carbon transport & logistics

• Electric vehicle (EV) fleets, vans and specialist vehicles; on-site or public charging infrastructure.
• Fleet replacement structured via asset finance to match asset life and tax allowances.

Circular economy & waste reduction

• Recycling machinery, food-waste digesters, water-recycling systems and sustainable packaging lines.
• Often eligible for asset finance, leasing or blended financing alongside grants.

Sustainable buildings & compliance upgrades

• Major retrofit projects, BREEAM improvements, EPC upgrades and energy management systems.
• Finance can cover design, capital works and interim cashflow during delivery.

We typically help businesses seeking finance from around £10,000 up to several million, and we match you to lenders/brokers who specialise in the right project size and sector.

Finance options we can introduce

Fast Business Loans does not lend. We introduce you to lenders and brokers who specialise in the finance types listed below. Each option has its strengths depending on project size, security and cashflow needs.

Finance type	Typical uses	Key features
Unsecured sustainability loans	Small to medium efficiency upgrades, consultancy costs	Quick decisions, minimal asset security, often higher rates than secured finance
Asset finance / hire purchase	Solar arrays, EVs, machinery	Spread cost over life of asset; repayments matched to asset performance
Invoice & cashflow solutions	Bridge delays (e.g. grant claims) or fund staged project delivery	Improves liquidity with flexible drawdown
Commercial mortgages / refinance	Large-scale retrofit or property-backed upgrades	Lower cost of capital, release equity for sustainability capex
Grants & blended finance (signposted)	Combine with loans to reduce net cost	Subject to separate eligibility — our partners can advise on compatibility

Compliance note: Any grant information provided by partners is subject to separate eligibility and administration outside Fast Business Loans’ control.
