Each trade and contract type carries a distinct risk profile. Here's what matters for yours.
Building & Principal Contractors
Building & Principal Contractors
Principal contractors carry vicarious liability for the whole site — including the actions of subcontractors. Your insurance programme needs to reflect the full contract value and the risk of design decisions.
- JCT contract minimum limits & wording compliance
- Subcontractor default and vicarious liability
- Structural / notifiable works exclusions
- CAR limits vs. full reinstatement value
Key Coverage Note
CAR limits should reflect the full reinstatement value of contract works — not just your fee or a fraction of the build value.
HVAC, Mechanical & Electrical
HVAC & M&E Contractors
M&E contractors often carry design responsibility alongside installation. A faulty system causing property damage or business interruption can generate claims far exceeding the contract value.
- Design and specification liability
- Fire and flood from faulty installation
- Testing and commissioning incidents
- Products liability for installed plant
Key Coverage Note
PI cover for M&E contractors should include a products liability extension — standard PI policies often exclude installed plant from cover.
Electrical Contractors
Electrical Contractors
From domestic rewires to commercial fit-outs, electrical contractors face significant liability for fire damage arising from their work — often years after project completion.
- Fire following electrical fault (completed operations)
- Certification and testing liability
- Part P compliance exposure
- Commercial fit-out property in care risk
Key Coverage Note
Ensure your PL policy includes a "completed operations" extension — work done today can generate a fire claim years later, after the standard policy period.
Agricultural & Rural
Agricultural & Rural
Agricultural businesses combine employer, vehicle, machinery, livestock and property risks in a single operation — often requiring specialist rural insurers with appetite for the full risk profile.
- Agricultural machinery on public roads
- Agri-chemical and pollution liability
- Seasonal worker employers liability
- Farm property and livestock cover
Key Coverage Note
Standard contractor policies rarely cover agricultural operations — specialist rural insurers with genuine appetite for the sector are required.
Flooring, Interiors & Shopfitting
Flooring & Interiors
Interior contractors working on occupied commercial premises face property in care risk and often need to satisfy retailer or landlord insurance requirements before work begins.
- Property in care, custody and control
- Hot works on occupied premises
- Retail tenancy insurance requirements
- Damage to existing finishes and structures
Key Coverage Note
Check that your PL policy includes adequate "property in care, custody and control" limits — this is frequently sub-limited or excluded on standard policies.
Other Specialist Trades
Roofing, Groundworks & Civil Engineering
High-risk trades require specific insurer approval. Roofing, groundworks and civil engineering contractors frequently encounter exclusions on standard PL policies that can leave significant gaps.
- Works at height exclusions (above 3m)
- Underground and excavation risks
- Vibration and subsidence liability
- Water ingress during roofing works
Key Coverage Note
Always declare works at height, hot works, excavation and demolition to your broker — non-disclosure on these activities is a common cause of claim rejection.
