Construction plant is one of the most valuable—and vulnerable—assets on any building site. Whether you own machinery or regularly hire equipment, having the right plant or hired-in plant insurance in place is critical to protect your business from costly losses.

As one of the UK’s leading construction insurance brokers, we’ve seen a surge in the number of requests for plant insurance this year as the UK’s construction sector has boomed.  We’ve been surprised (and slightly alarmed in some cases) by how little many plant users know about construction plant insurance.  To help, we’ve put together this guide. It explains everything you need to know about construction plant insurance and hired-in plant insurance in the UK, including what’s covered, what’s not, costs, and how to choose the right policy.

We hope this guide will prove useful.  If you’d like some help or an insurance quote, then please get in touch.  You can call us on 01482 434343, request a callback, or get a plant insurance quote.

What is Construction Plant Insurance?

Construction plant insurance covers owned and hired-in plant machinery and equipment against risks such as:

• Theft
• Accidental damage
• Fire and flood
• Vandalism
• Damage in transit
• Road use
• Loss

It applies whether your plant is:

• On-site
• In storage
• Being transported between jobs
• Owned by you
• Hired-in plant

In short: if your business owns or rents equipment, this policy protects it.

What is Hired-In Plant Insurance?

Hired-in plant insurance covers equipment you rent or lease from another company.  Hired plant is the most common type now, owing to its flexibility and lower costs, and a hired-in plant insurance policy will cover you if the equipment is:

• Accidentally damaged
• Stolen
• Destroyed
• Lost

Do You Need Hired-In Plant Insurance in the UK?

While it’s not a legal requirement, in practice:

• Most hire companies require it
• Contracts make you responsible for the equipment
• Without it, you could face full replacement costs

With the cost of replacing plant like a JCB digger easily costing over £80,000 and a hired plant policy costing as little as £20 a month, it’s easy to see why so many people take cover out.

What Does Construction Plant Insurance Cover?

Most policies include:

• Theft (subject to security conditions)
• Accidental damage
• Fire and flood
• Malicious damage
• Plant in transit
• Tools cover
• Own plant and hired-in plant combined policies for firms that own and rent equipment
• Continuing hire charges – for hired-in plant

What Are Continuing Hire Charges?

If hired equipment is damaged or stolen, you may still need to pay hire fees.  Your plant policy will cover this for up to 90 days or more, depending on your policy’s limits

What Is NOT Covered By Plant Insurance?

Standard policies typically exclude:

• Mechanical or electrical breakdown
• Wear and tear
• Negligence or misuse
• Unattended plant without proper security
• Theft where security conditions aren’t met
• Malicious damage

Own Plant vs Hired-In Plant: What’s the Difference

Many insurers offer combined policies for simplicity and cost savings.

What Types Of Plant Can Be Covered?

Policies typically cover:

• Excavators and diggers
• Dumpers and rollers
• Telehandlers
• Cranes
• Cherry pickers
• Scissor lifts
• Tar sprayers
• Steam rollers
• Generators and compressors
• Site equipment
• Forklift trucks
• Mini diggers

Some policies can include handheld tools, but usually only as an extension.

Is Plant Covered Overnight?

Yes, but only if strict security conditions are met, including:

• Immobilisers are fitted
• Locked compounds
• CCTV or site security is in place
• Keys removed and stored securely

Failure to meet these conditions is one of the most common reasons for rejected claims.

Does Insurance Cover Theft?

Yes, but insurers take theft risk seriously.

To stay covered:

• Install trackers or immobilisers
• Avoid leaving the plant unattended in unsecured areas
• Follow all policy security requirements

Plant thefts are on the rise in the UK.  According to Abax, plant theft costs UK construction firms between £800m and £1bn per year.  Thefts are rising, so more insurers are looking at security before issuing quotes.

Does Plant Insurance Cover Operator Error?

✔ Yes—accidental damage caused by operators is usually covered

❌ No—deliberate misuse or gross negligence is excluded

What Is The ‘Single Item Limit’?

This is the maximum payout per item under your policy.  For example:

• Your policy’s overall claim limit is £100,000
• Your single item limit is £25,000

Any single item above this amount must be specified separately.  So, if you have a crane worth £500,000, you’ll need to list that as a separate item on the policy.

Is Plant Covered In Transit?

Most policies do include transit cover, protecting machinery while being moved between sites.  It’s worth checking for whether it cover:

• Loading/unloading cover is included
• Cover extends to third-party hauliers
• If there are any geographic limits

What Affects the Cost of Plant Insurance?

Premiums depend on:

• Value of equipment
• Type of machinery
• Claims history
• Security measures
• Location of work
• Level of cover
• The size and nature of the project you are working on
• The level of training/ages of the operators

How Much Does Construction Plant Insurance Cost?

The following gives you a rough guide as to the cost of plant insurance:

• Small contractors: £300–£1,000 per year
• Medium businesses: £1,000–£5,000+
• High-value fleets: significantly more

Hired-in plant insurance quotes are often priced based on:

• The value of the equipment being hired

How to Reduce the Cost of Plant Insurance

You can lower premiums by:

• Installing GPS trackers
• Using immobilisers
• Securing sites properly
• Increasing voluntary excess
• Maintaining a clean claims history
• Bundling policies (e.g. with liability insurance)
• Registering owned plant with the CESAR scheme

What’s The Difference Between Plant Insurance vs Contractors’ All Risks (CAR)?

Plant insurance covers machinery and equipment.  Contractors’ all risks cover works in progress, materials and contract risks such as unforeseen delays.   Many construction firms combine both for full protection.
