Quick tips for choosing/contacting a broker

• Match broker size to your needs: use specialist HGV brokers for single trucks / small fleets; use national/global brokers for large or complex fleets or international work. (See grouped recommendations above.) (avisinsurance.co.uk, ajg.com)
• Look for: haulage experience, Goods‑in‑Transit cover, employer/public liability, claims handling, telematics/driver risk services and RHA/CMR familiarity. (marshcommercial.co.uk, ajg.com)
• Get multiple quotes and ask each broker what insurers they can access for HGV risks — panels vary and that affects price/terms. (signatureunderwriting.com, fleetcompare.co.uk)

What to have ready when you contact them

• Fleet size and vehicle types (GVW, trailers), primary operations (UK only / continental / international), annual mileage, driver details (ages, licence history), claims history (last 3–5 years), goods carried and any subcontractors used. These speed up accurate quotes. (simplyquote.co.uk, marshcommercial.co.uk)
