Planning a Biomass Installation

Biomass systems are an excellent renewable heat option. For many there will be substantial cost savings by investment in the most widely deployed form of renewable energy.

It is possible to install a biomass heating system in a new build project, or to retrofit a system into an existing building or complex of buildings. The technical and financial viability of this will be based upon a clear assessment of your heat needs and then a structured planning process to make the right choices.

This section provides a step by step explanation of the key project phases and considerations required to achieve this.

However, biomass systems are complex and you will typically need support from a range of specialists to realise your project.

Typical Project Phases Key Activities Who What you need to know
1. Pre-feasibility Establishes initial technical and economic viability and case for investment. Consultant or in-house, depending on expertise available.


2. Full feasibility
  • Operating profile of heat system
  • Current energy requirement
  • Future energy requirements
  • Fuel prices now and in future
  • Estimated system size
  • Outline design concept
  • Project timeline
  • Budget cost
  • Overall case for investment

3. Detailed Design
  • Design concept agreed with client,
  • Consulting engineer appointed to work through detailed design of:
    • System sizing
    • Fuel reception and handling system
    • Civils and building design
    • Combustion system and boiler specifications
    • Heat distribution system
    • Controls and integration
Typically the biomass installer under a ‘design and build’ contract.
4. Permissions & Consents
  • Planning permission sought for any new structure or modification of existing structures
Client or biomass installers
5. Procurement
  • Procurement of boiler and their components.
  • Procurement of integrations and enabling works to heating system
  • Visits to example sites and possibly manufacturer facilities
  • Maintenance contract
  • Contractual terms and conditions agreed.
Client or consultant
6. Construction & Installation
