Contractors and construction firms insurance in London

London contractors and construction firms 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. General contractors and construction firms cover the widest liability spectrum — from small refurbishments to major projects. Cover scales with the largest single-project exposure.

Key covers for contractors and construction firms

• Public liability — £5m-£10m minimum; up to £25m for larger projects.
• Employers liability — £10m — more for larger firms.
• Contract works — Site materials, temporary works, buildings under construction.
• Plant and machinery — Owned or hired plant.
• Commercial vehicle / fleet — Van, LGV, and specialist vehicle cover.
• Professional indemnity — For design-and-build or principal designer roles.
• Product liability — For any manufactured items supplied.
• Business interruption — If premises damage stops trading.

London-specific considerations

• ULEZ compliance — commercial vehicles that don't meet Euro 6 diesel or Euro 4 petrol standards face daily charges across all 32 boroughs, and tradespeople quoting for central jobs need to factor van-replacement or daily charge exposure into insurance and pricing.
• Congestion charge zone — the £15 daily charge applies to most vans working in the central zone Monday to Friday 7am-6pm and weekends 12-6pm; contractors doing repeated central London jobs often need commercial vehicle policies that recognise the additional wear and higher mileage.
• Terraced Victorian and Georgian stock — large tracts of inner London (Camden, Islington, Hackney, Southwark, Lambeth) are solid-wall pre-1919 housing with shared party walls, complex service runs, and heightened damage-to-neighbour exposure that public liability limits should reflect.
• Listed-building concentration — Kensington, Chelsea, Westminster and the City hold a high density of Grade II and Grade II* listed properties where any works need listed-building consent and any accidental damage is treated more seriously by insurers and by local authorities.
• High tourist and retail footfall — work on shopfronts, restaurants and hotels in the West End, Covent Garden and around major stations exposes tradespeople to third-party injury and business-interruption claims from unusually high public exposure.
• Corporate and estate clients — managing agents, property companies and Crown Estate contracts routinely require £5m-£10m public liability and named-broker documentation; a sole-trader £2m limit rarely clears procurement.
