Installing machinery is one of those phases where everything is in motion: expensive kit is being moved, lifted, aligned, wired, programmed, and tested—often while multiple contractors are working in the same area. A small mistake can mean a big loss: a dropped component, a damaged control panel, a fire during hot works, or a commissioning fault that takes a line out for weeks.
Machinery installation insurance (often referred to as Erection All Risks (EAR), Contractors’ All Risks (CAR) with an installation section, or Installation All Risks (IAR)) is designed to cover physical loss or damage to the machinery and associated works during the installation period—typically from arrival on site through to testing and handover.
This guide explains how the cover works in the UK, what to look for in a policy, and how construction and engineering firms can avoid the common gaps.
Machinery installation insurance is a specialist construction/engineering policy that covers sudden and unforeseen physical loss or damage to:
It is most relevant where the project involves mechanical and electrical (M&E) works, industrial plant, production lines, HVAC systems, lifts, escalators, renewable energy equipment, and complex control systems.
The label matters less than the scope, period of cover, testing/commissioning terms, and exclusions.
Cover varies by insurer and wording, but a well-structured installation policy usually includes the following.
Some policies can include cover while the machinery is:
This is a common gap. Many firms assume “it’s covered once it’s ours,” but transit may sit under a separate goods in transit policy, a supplier’s cover, or specific project insurance.
If machinery is stored on site before installation, the policy may cover damage from:
Check whether the insurer requires specific security measures (fencing, CCTV, locked containers, out-of-hours alarms, etc.).
This is the core of the cover: damage during assembly and installation, including:
Typical insured events include accidental damage, collapse during lifting, impact, and certain types of water damage.
Testing is where losses can become expensive quickly. A good policy will clearly define:
Some policies restrict cover during testing or apply stricter exclusions for defects and faulty workmanship.
Many project policies combine installation cover with public liability for:
This is crucial if you’re working in a live environment (e.g., a factory still operating, a hospital wing, or a commercial building with tenants).
If you’re installing machinery inside an existing building, you may need cover for:
This is often handled via an “existing property” extension with strict conditions and sub-limits.
Physical damage is one thing; the bigger cost can be the delay. Some projects buy Delay in Start-Up (DSU) or Advanced Loss of Profits (ALOP) to cover financial loss caused by insured damage delaying commissioning.
This is more common on large industrial and renewable energy projects.
Installation policies are “all risks” in concept, but exclusions matter. Common ones include:
Most policies exclude the cost of rectifying the defective part itself, but may cover resultant damage. The exact split varies.
Example: If a poorly torqued bolt fails and damages a gearbox, the bolt may be excluded but the gearbox damage may be covered—depending on wording.
Not intended for maintenance issues or gradual damage.
Once the machinery is handed over, breakdown is usually covered under machinery breakdown (engineering insurance), not installation cover.
If commissioning involves software, PLC programming, remote access, or network integration, check cyber exclusions. You may need separate cyber cover.
Theft cover often depends on security conditions and evidence of forced entry.
Fire claims can be declined if hot works permits, fire watches, or housekeeping standards weren’t followed.
Often excluded or heavily restricted unless specifically endorsed.
This cover is relevant for multiple parties, and the “right” policy structure depends on contract terms.
If you’re responsible for the works until handover, you’re exposed to damage during installation and testing.
If you’re managing the site and subcontracting installation, you may still carry responsibility under the main contract.
If the supplier’s scope includes installation/commissioning, they may need project cover or to be named on the principal policy.
If you’re installing in your own facility, you still face the same risks—especially where the installation is complex and downtime costs are high.
This is where a lot of policies look “fine” until a claim happens.
Confirm:
If the contract includes a defects period, you may need a maintenance extension.
Make sure the sum insured reflects:
Underinsurance can reduce claims payments.
Ask:
Installation policies often have:
Choose excesses that match your cashflow and risk appetite.
Your contract may specify:
If the contract says the principal contractor arranges cover, ensure subcontractors are included and the scope matches their work.
Insurers may require:
If these conditions aren’t met, claims can be disputed.
Here are common loss scenarios during setup:
The best outcomes happen when the project has clear documentation: delivery notes, photos, method statements, permits, and commissioning records.
You don’t need to be perfect—just consistent.
A quick way to avoid buying the wrong cover.
CAR often focuses on building works. It can include installation, but you must confirm the installation section is suitable for high-value machinery and testing.
This is usually for operational machinery after handover. It covers sudden breakdown, often including electrical/mechanical failure, but it’s not designed for the installation phase.
These cover injury and third-party property damage (and employee injury), not damage to the machinery you’re installing.
If you design or specify the system, PI covers claims arising from professional negligence—not physical damage during installation.
To quote accurately, insurers typically want:
The clearer you are upfront, the fewer surprises later.
Often, yes in practice. EAR is a common label for erection and installation risks, especially on engineering-heavy projects. The key is the wording and extensions, not the name.
Usually it covers resultant damage but excludes the cost of rectifying the defective work itself. The exact position depends on the policy clause.
Sometimes automatically, sometimes with restrictions. Always check the testing clause, sub-limits, and excesses.
Maybe. You need to confirm the CAR policy includes installation and testing for your scope, and that you’re included as an insured party (often on a joint names basis).
Theft is commonly covered but subject to security conditions and evidence requirements. If you’re storing high-value components, make sure the security measures match the policy.
It can, but usually only by endorsement with sub-limits and strict conditions. This is important for retrofit projects.
Machinery installation insurance is one of those policies where the detail matters. If you’re installing high-value equipment, working in a live environment, or commissioning is complex, it’s worth structuring the cover around your contract responsibilities and the testing period.
If you want, share the project type (e.g., HVAC plant room, production line, lift install), the approximate machinery value, and whether hot testing is required—and I’ll outline the most sensible cover structure and the key clauses to request.
