Single-Project Contract Works Insurance

Not every contractor wants an annual policy. For a one-off build, a large single contract or a job where the client demands project-specific cover, single-project contract works insurance covers that one job — from starting on site through to practical completion and the maintenance period.

In short

Single-project contractors’ all risks (contract works) insurance covers one specific construction contract — the works, materials, existing structures and plant — for the project duration plus its maintenance and defects period. Ideal for one-off jobs and JCT or NEC contracts that require cover in joint names.

When a single-project policy is the right call

It fits a one-off or unusually large contract, a job outside your normal annual turnover, or a contract whose conditions require project-specific cover in joint names with the employer. For contractors doing regular work, an annual contractors’ all risks policy usually works out simpler — single project is for the standalone job.

What it covers

The permanent and temporary works and materials, existing structures where you are working on or adjoining them, contractors’ plant, and extensions such as delay in start-up (on referral), third-party liability and terrorism via Pool Re. The cover is written for the specific project rather than a rolling programme.

Project period and maintenance

Cover runs for the construction period and then through the maintenance / defects-liability period, and can be extended if the programme slips or the maintenance term is longer. Getting the period right matters: cover that ends at practical completion can leave you exposed during snagging and defects.

JCT and NEC alignment

Standard construction contracts set out who insures the works and on what basis — the JCT insurance Options A, B and C, joint-names requirements, and non-negligence cover under clause 6.5.1. We line the policy up with the contract you are signing. Our guide to JCT insurance options explains how they differ.

Large and complex single projects

High-value single contracts are considered on their own merits, rated on a probable-maximum-loss basis, with capacity for substantial projects available through specialist, Lloyd’s-backed markets. The bigger and more complex the job, the more the presentation of the risk matters — which is where a specialist broker earns its keep.

Frequently asked

Annual or single-project — which do I need?

If you take on contracts regularly, an annual contractors’ all risks policy is usually simpler and cheaper per job. Single-project cover suits a one-off, an unusually large contract, or a job where the client requires project-specific cover.

Will it meet my JCT/NEC requirements?

Yes — the policy is arranged to match the insurance option and joint-names requirements in your contract, including non-negligence cover where the contract calls for it.

What is the maintenance period?

It is the defects-liability period after practical completion during which you remain responsible for making good defects. Cover can be arranged to run through it and extended if needed.

How large a contract can be covered?

Substantial single contracts can be placed, rated on a probable-maximum-loss basis through specialist markets. The limit is set to the project rather than a standard cap.
