Burner performance depends on the appliance, fuel supply, combustion air, flue and controls; a burner adjustment should not be treated as a complete plant assessment.
What the work can include
The agreed scope can include burner and appliance assessment, combustion-related servicing or repair scope, controls checks and recorded findings. The agreed scope names burner and appliance checks, readings and defects and states what will be supplied or tested at completion. Additional repairs, specialist design, testing or replacement are separate unless expressly included.
At completion, the owner or agent receives burner and appliance checks, readings and defects; any access limitation and the next job decision are stated.
Important decisions
Set boiler service and combustion-maintenance questions against the appliance and fuel. Relate this choice to the property condition, access arrangement and owner or agent’s next instruction.
Assessment and preparation
Before arranging the work, provide appliance and burner details, fuel type, fault history, manufacturer information, flue arrangement, access and operating duty. For a managed or shared property, identify the owner, occupier, managing agent and person authorised to approve access or additional work.
Provide the appliance and burner details, fuel, fault history, manufacturer information, flue arrangement and operating duty. Confirm the isolation and testing constraints.
How the work proceeds
Identify the equipment, confirm the authorised scope and competence, inspect and test the agreed components, record readings or defects and define follow-on work. At handover, the owner or agent can use burner and appliance checks, readings and defects to decide the appliance, flue or combustion follow-up.
Cost, timing and disruption
Scope and price are affected by fuel, access, isolation, test requirements, parts, flue interfaces and any production or occupancy constraints. For a property job, provide the access arrangement, occupier or agent contact and any restriction on use relevant to burners and combustion equipment.
Sector and property applications
Owners, landlords, managing agents and occupiers may need burners and combustion equipment scoped around fuel, combustion air, flues and safe isolation. The sector directory provides the wider property context.

Frequently asked questions
Does burner servicing include the boiler?
Not automatically. Burner work may be one part of appliance servicing; the boiler, controls, flue, fuel supply and combustion scope should be named in the instruction. For a property job, confirm burner and appliance checks, readings and defects with the owner or agent before work is arranged.
What can cause unstable combustion?
Possible causes include fuel or air supply, burner condition, controls, appliance adjustment, flue restriction or another system fault. Testing must establish the cause rather than assume adjustment is enough. Access through occupied rooms, shared areas or neighbouring land should be agreed with the occupier or agent before the visit.
Can a burner be replaced without checking the flue?
No. The flue and combustion-air arrangement must be compatible with the replacement burner and appliance, and the completed work requires the appropriate checks and commissioning. The job decision should distinguish immediate making-safe work from a later repair, replacement or improvement instruction.
Are combustion readings part of every visit?
The required readings depend on the appliance, manufacturer instructions and agreed task. The handover should state which combustion checks were completed, their limits and any follow-on action. At handover, give the owner or agent the property-specific record, outstanding action and any restriction on use.
Knowledge and guidance
Read how often a commercial boiler should be serviced and commercial boiler replacement considerations to set boiler service and combustion-maintenance questions against the appliance and fuel. Use the service assessment to apply that guidance to the property or site. For a property job, use this guidance alongside condition, access and the owner or agent approval route.
