Hired-in plant

Equipment insurance will help protect your legal liability under the terms of your hiring agreement to pay compensation for damage to hired-in plant, whilst in your custody or control.

What additional builders all risk insurance covers are available?

Non-negligence (JCT insurance)

Non-negligence insurance, otherwise known as JCT 6.5.1, helps protects against claims should there be damage to a neighbouring property due to the works carried out arising from collapse, subsidence, heave, vibration, weakening or removal of support, or lowering of groundwater, which is not the result of negligence.

Business interruption

Business interruption insurance protects against the loss of income from being unable to trade as a result of an insured event (i.e. property damage). The contractor's all risk cover will help protect against the consequential loss of the interruption to trade by indemnifying the policyholder for the loss of income as a result of the insured peril.

How your contractors all risk insurance cost (£) is calculated?

How insurers calculate your contractors all risk insurance cost will depend on a number of factors because each provider will have their own method of assessing your risk of claim. However, there are common areas that underwriters will focus on calculating your contract works insurance cost:

Contract value

How much contract works insurance you will require will be a significant price determining factor. If a fire were to destroy the build you were responsible, the size of the maximum possible loss will impact your premium cost calculation.

Type of project

Basement works, timber construction, demolition works, quarrying, tunnelling, flood exposed areas, road construction, bridgework, external work on high-rise buildings, piling, ground stabilisation, underpinning, are all considered high risk and therefore increase your premium cost.

Security

Additional security features that will improve your risk profile and reduce your premium cost. These can include cameras, alarms, boundary fence, and 24 hour security.
