Biomass boilers can be a cost-effective low-carbon heating option for commercial buildings in the UK, but whether they are the lowest-cost depends on multiple factors, including building size, heating demand, and available alternatives.

Is Biomass the Lowest-Cost Option for Commercial Heating?

✅ Yes, if:

• Your building has high heat demand (e.g., hotels, schools, warehouses, hospitals).
• You have space for fuel storage and delivery.
• You are in a rural or off-grid location where gas isn’t available or the gas connection is expensive.

❌ No, if:

• You have a small, well-insulated building suited for heat pumps.
• You’re in an urban area where district heating is an option and deliveries could be awkward.
• You lack space for fuel storage or want a low-maintenance system.

Cost Analysis of Biomass Heating for Commercial Buildings

Upfront Costs

• Commercial biomass boiler systems (for LTHW) range from £150kW to £200kW, depending on capacity and fuel type, steam system can be £250-£300/kW.
• Additional costs for fuel storage, flue systems, and Mechanical and Electrical services.
• Overall costs are generally lower than heat pumps.

Fuel Costs

• Biomass fuel (wood chips, pellets, or logs) is cheaper than electricity but can vary in price:
  • Wood chips: ~£60-£140 per tonne (cheapest option for large-scale use)
  • Wood pellets: ~£280-£320 per tonne (higher energy density, but pricier)
  • Logs: ~£100-£150 per tonne (best for small-scale or rural use)
• Biomass fuel can be cheaper than gas, especially with rising fossil fuel prices.

Operational & Maintenance Costs

1. • Biomass boilers require regular maintenance, including ash removal and fuel delivery.
   • Higher servicing costs compared to gas or heat pumps.
   • Automated systems reduce labor but increase initial investment.
   
   

   Government Incentives & Grants

   • The Boiler Upgrade Scheme (BUS) primarily supports heat pumps, and only residential
   • Previously, the Renewable Heat Incentive (RHI) made biomass more attractive, but this ended in 2021.
   • Some local grants and tax benefits (e.g., Super Deduction for capital investments) may still apply.
