What Fuelcare does

Fuelcare Limited is a UK-based specialist in fuel quality management, founded in 1989 and headquartered in Shrewsbury. The company addresses microbial contamination, fuel instability, and water/particulate issues across diesel, gasoil, and residual fuels through a portfolio of fuel biocides and chemical additives, engineering systems including the A.I.S. fuel polishing unit and the ClearFuel conditioning platform, and IoT-based remote fuel monitoring services deployed across more than 2,400 active sites with 850+ engineering systems installed. Its customer base spans marine, offshore, rail, defence, aviation, data centres, power generation, and bus transportation sectors, with regulatory approvals including BPR biocidal registrations, Achilles UVDB, JOSCAR, MoD supplier status, and Lloyd's Register and ClassNK type approvals for marine applications.

The business model combines one-off chemical sales (biocides and additives), capital equipment sales (A.I.S. and ClearFuel units), and recurring service revenue from IoT monitoring subscriptions and maintenance contracts. Fuelcare generates approximately 500 million gallons of treated fuel annually and distributes through a combination of direct sales in the UK and a global partner network with warehouses in Aberdeen, Malaysia, Singapore, and other jurisdictions. Founder-managed with 1-10 employees, the firm has co-authored the Energy Institute's EI Standard 1566 on bunker fuel delivery best practice and holds IATA Strategic Partner status, positioning it as a standards-influencing niche specialist rather than a volume chemical supplier.

Revenue model

1. Fuel Biocide and Additive Products: Sale of hydrocarbon fuel biocides (FuelClear M15, FuelClear M68, Kathon FP 1.5) and fuel additives (CarbonClear detergent, CorroClear 100 corrosion inhibitor, OptiClear stability improver) directly to operators and through distributor network. Products are BPR approved and registered for UK and EU use. Revenue from product sales forms the core of the business model.
2. Fuel Engineering Systems: Design, fabrication, and sale of engineered fuel treatment systems including A.I.S. additive injection systems and ClearFuel polishing systems. Systems are engineered to customer specification, manufactured in-house in UK workshops, validated before deployment, and sold as turnkey solutions. Optional IoT monitoring available as add-on.
3. IoT Monitoring Services: Subscription-based real-time monitoring services for storage tanks, fuel dispensing, and additive dosing. Cloud-based dashboards provide 24/7 visibility, automated anomaly alerts, and historical analytics. API integration with existing fleet management and SCADA systems. Typically bundled with engineering system sales or sold as standalone service.
4. Fuel Testing and Laboratory Services: Accredited laboratory fuel testing services using ASTM, IP, and ISO methodologies covering water content, microbial contamination, particulate levels, and chemical degradation. Includes on-site fuel sampling following ISO 3170 and ASTM D4057. Revenue from per-test pricing and sampling service visits.
5. Site Fuel Sampling Services: Professional on-site fuel sampling services performed by Fuelcare technicians at customer sites. Samples collected from tank bottoms, mid-tank levels, delivery lines, and dispensing points following ISO 3170, ASTM D4057, and Energy Institute guidelines.

Core offering

Fuelcare develops, manufactures, and supplies hydrocarbon fuel biocides (FuelClear M15, Kathon FP 1.5, FuelClear M68), fuel additives (CarbonClear detergent, CorroClear 100 corrosion inhibitor, OptiClear stability improver), and engineered fuel treatment systems (A.I.S. automated additive injection systems, ClearFuel multi-stage fuel polishing systems). The company complements these physical products with accredited laboratory fuel testing, on-site fuel sampling, and an IoT-enabled monitoring platform providing real-time visibility of fuel storage, dispensing, and dosing across marine, offshore, rail, defence, aviation, power generation, and data centre operations.

Product overview

Fuelcare offers a comprehensive fuel treatment portfolio comprising three product lines: fuel biocides (FuelClear™ M15, Kathon™ FP 1.5, FuelClear™ M68), fuel additives (CarbonClear™, CorroClear™ 100, OptiClear™), and engineered systems (A.I.S.™ Additive Injection Systems, ClearFuel™ Fuel Polishing Systems). These are complemented by three monitoring services (Site Fuel Sampling, Fuel Testing, Storage Tank Data Monitoring, Fuel Dispensing Data Monitoring) unified through a centralised IoT Dashboard platform. The portfolio is designed as an integrated ecosystem where biocides and additives address contamination and fuel degradation, engineering systems enable precision dosing and fuel polishing, and monitoring services provide real-time visibility and data-driven decision support across marine, offshore, defence, aviation, and rail sectors.
