Heating engineers insurance in Trowbridge

Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Published 16 July 2026

Trowbridge heating engineers need cover shaped to how the trade actually works — public liability, employers liability where staff are on the books, tools in vans, and often trade-specific extensions. Heating engineers cover boilers, radiators, underfloor systems, heat pumps, and increasingly renewable installations. Each brings different claim exposure.

Frequently asked

Do MCS installers need special cover?

Standard PL covers installation but MCS-related performance claims may need PI extension. Discuss at placement.

What about heat pump failures?

Heat pump underperformance claims are increasing. Product liability plus PI extension worth considering.

How much does heating engineers insurance cost in Trowbridge?

Depends on turnover, staff, van, tools value, and cover level. Sole trader with PL and tools: often £300-£700. Established firm with staff and fleet: £1,500-£5,000+. A specialist broker gives a firm figure once details are shared.

Do I need employers liability in Trowbridge?

Only if you employ others — then it's legally required at £5m minimum. Sole traders with no staff are exempt.

Are tools covered on my van insurance?

Not automatically. Tools-in-transit is a separate cover or extension. Ask specifically.
