Non negligent insurance provides protection against damage to third party property arising from construction works where no fault or negligence can be established. Commonly required on complex developments carried out in close proximity to existing buildings, this cover gives developers, funders and adjoining owners confidence that unforeseen damage will be addressed without the need for lengthy disputes over liability.
When is Non Negligent Insurance Required?
Non negligent insurance is often required where construction works present a higher risk to neighbouring structures, particularly on urban or constrained sites. It is commonly specified within building contracts, including JCT forms, where clause 6.5.1 sets out the obligation to maintain cover for non negligent damage.
The policy may also be requested by funders, freeholders or adjoining owners as a condition of consent to works. It is frequently used on basement excavations, refurbishments, conversions and developments involving structural alterations near existing buildings.
