Heating engineers insurance in Thornbury

Reviewed by Apex Insurance Brokers · Published 16 July 2026

Thornbury 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.

Key covers for heating engineers

Public liability — £2m-£5m for installation-related damage or injury.
Employers liability — £10m if you have staff.
Tools cover — Radiator keys, brazing kit, meters, specialist heating equipment.
Commercial vehicle — Van cover with class-of-use for heating contracting.
Gas Safe extension — For any gas boiler work.
MCS extension — For Microgeneration Certification Scheme installers (heat pumps, solar thermal).

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 Thornbury?

We do not publish premium figures, because a figure that is wrong at the point of buying is worse than no figure at all. What actually moves the price is your turnover, the mix of work you take on, how many people you employ, the value of tools, plant and materials you need covered, the limits and excess you choose, and your claims record. Give us those and we will come back with a real figure from the market rather than a guess.

Do I need employers liability in Thornbury?

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.
