- Equipment finance lenders and leasing companies look for auto and inland marine coverage on service vehicles and diagnostic tools.

Exclusions
What Boiler Servicing & Maintenance Contractors does not cover
- Boiler servicing and maintenance contractor insurance concentrates on liability, auto, property and workers' compensation, so several exposures sit outside the benchmarked lines.
- Professional liability for design or engineering advice, cyber liability, and employment practices liability are not included and must be added separately.
- The general liability form carries the standard "your work" and faulty-workmanship carve-outs, so the cost to redo a defective boiler repair is a business risk, not a covered loss.
- Pollution liability is not scheduled here, leaving fuel, combustion byproduct, and asbestos-insulation releases largely excluded under the pollution exclusion.
- Contractual liability assumed beyond a standard hold-harmless, and wear or mechanical breakdown of the customer's own boiler, also fall outside these coverages.
Risk advisory
Typical coverage gaps in Construction & Trade Contractors
Boiler servicing and maintenance contractors carry a heavy completed-operations exposure because a faulty repair can cause a failure, scalding, or property damage long after the crew leaves.
- Confirm products-completed operations limits are adequate and kept in force after each job, since claims often surface on a delay.
- Add contractors pollution liability to respond to combustion byproducts, fuel oil, and disturbed asbestos insulation that the standard pollution exclusion removes.
- Because technicians travel constantly, verify hired and non-owned auto is in place and that inland marine schedules cover portable diagnostic and welding equipment on the road.
- Where welding is performed at the shop, review property and fire limits.
- Finally, secure additional-insured and waiver-of-subrogation endorsements before starting work for a general contractor or facility owner so contract requirements are met and the account remains bindable.
FAQ
Frequently asked questions
What insurance do boiler maintenance contractors need?
Boiler servicing and maintenance contractors typically need general liability, workers' compensation, employer's liability, commercial auto, and inland marine for tools and diagnostic equipment. Products-completed operations coverage is essential because defective repairs often fail after the job ends. Many facility owners and general contractors also require additional-insured status and a fidelity bond before crews are allowed on site.
Does general liability cover a defective boiler repair?
General liability for boiler servicing contractors covers third-party injury and property damage but not the cost to redo the faulty repair itself, which the 'your work' exclusion removes. Damage that a failed repair causes to other property may be covered under completed operations. Carry adequate completed-operations limits and keep them active after the job to respond to delayed claims.
Do boiler contractors need pollution liability insurance?
Boiler servicing contractors benefit from contractors pollution liability because standard general liability excludes releases of fuel oil, combustion byproducts, and disturbed asbestos insulation. Servicing older boilers frequently disturbs regulated materials, and an unexpected release can trigger cleanup and third-party claims. A dedicated pollution policy fills a gap that the general liability pollution exclusion leaves open.
