Machine Shop Insurance: What Fabrication Shops Should Know About Coverage, Risk and Downtime

Machine shop insurance is more than a policy you renew without reading. A fabrication shop has expensive machines, flammable dust, heavy material, customer parts on the floor and deadlines that don't move when a machine stops. The right cover depends on what would actually hurt your business if it went wrong.

This guide covers the main types of cover, the decisions shop owners get wrong, and how to review your insurance each year. It applies to shops in the US, UK and Australia, though policy names differ between countries. It isn't insurance advice. Every shop's policy should be set with a qualified broker or insurer.

Why machine shops need insurance

Most of a fabrication shop's value sits in a few machines. A laser, a press brake and the compressor and extraction that support them can be worth more than everything else in the building. Losing one to fire, damage or breakdown stops production, and the bills keep coming while it's stopped.

The risks are specific to the work:

• Fire in extraction systems and dust collectors
• Injuries from sheet edges, heavy plate, forklifts and press brakes
• Theft of tooling and stock
• Damage to customer parts and materials while they're in your care
• Lost revenue while a machine is down

Common types of machine shop insurance

Exact policies and names vary by country and insurer, but the main types are:

• Commercial property insurance. Covers buildings, contents, machines and stock against fire, theft, storm and similar events. Often sold as part of a business owner's policy (US) or a general business package (UK and Australia), sometimes bundled with cover for cash on the premises and employee fraud.
• General liability (public liability in the UK and Australia) and product liability. Covers claims from injury or damage caused by your business or the parts you supply.
• Workers' compensation (US and Australia) or employers' liability (UK). Covers staff injured at work. Compulsory for most employers in all three countries, and usually a separate policy.
• Business income (US) or business interruption (UK and Australia). Pays ongoing costs and lost margin while the business can't trade after an insured event.
• Equipment breakdown (US) or machinery breakdown (UK and Australia). Covers repairs, and sometimes lost revenue, when a machine fails mechanically or electrically.
• Commercial vehicle insurance. For delivery trucks and vans.

Property cover usually protects against external events like fire or theft. It won't pay when a machine simply breaks down. That needs equipment breakdown cover.

Equipment breakdown cover: a judgement call

Equipment breakdown insurance (called machinery breakdown in the UK and Australia) pays for repairs and, depending on the policy, the revenue and overheads you lose while the machine is down. It isn't cheap, and some experienced shop owners avoid it, because the payout terms can be opaque and hard to argue.

Whether it's worth it depends on how well you can recover on your own. A large shop with its own maintenance engineers and spare parts can often get a machine running again quickly. A small shop with one laser, no in-house engineer and no spares has nothing to fall back on. For that shop, a major breakdown can stop all cutting for weeks.

Plan for parts, not just the policy

Getting parts can matter more than paying for them. Some of this varies by laser brand, and by the extent of local support in your region.

One Tempus Tools customer we spoke to knew buying a Chinese laser was risky from this perspective. They found a brand where most of the laser was standard parts: sensors and components that could be sourced from many suppliers. The exception was the laser source and the cutting head. So they purchased a spare cutting head with the laser. It's often a better hedge against downtime than a breakdown policy.

Insure at the right value

The most common mistake is insuring machines for the wrong amount.

Don't over-insure lasers

Replacement cost cover (called new-for-old in the UK and Australia), which pays to replace a machine with a new one, is expensive. Many shops insure machines at their current value instead, called actual cash value in the US and indemnity value in the UK and Australia. Laser prices have dropped a long way, so a machine's current value and its replacement cost both fall over time. If you don't lower the insured value at each review, you're paying premiums on value that no longer exists.

Don't under-insure press brakes

Press brakes are the opposite. A well-serviced press brake holds its value for years. One shop paid around $350,000 for a press brake that would still sell for about $250,000 with its tooling, while its depreciated book value was closer to $150,000 to $180,000. Insuring it at book value would leave a large gap if it were destroyed.

Under-insuring can also cut your payout on smaller claims. Most property policies include a clause that reduces any claim in proportion to how far you're under-insured. It's called a coinsurance clause in the US and an average clause in the UK and Australia. If your assets are insured for half their value, a partial loss may only be half paid.

Look at what each machine would cost to replace on today's market, not what the depreciation schedule says.

Fire risk in fabrication shops

Machine fires are rare, but when they happen they're serious, and fire is where under-insuring hurts most.

The risk is in the dust. Cutting several materials on one laser puts mixed dust into the extraction system. Fine aluminium dust mixed with mild steel dust can ignite from a spark, and can explode. A strong filtration system on the extraction helps, along with keeping it clean.

Linishing and sanding are a classic source of fires. A belt used on mild steel and then on aluminium can start one. Keep separate belts for each material and use the right dust controls.

Tell your insurer what materials you process and how your extraction is set up. It affects your risk, and an insurer that doesn't know may dispute a claim.

Liability risks

Liability cover protects you when someone else is hurt or suffers a loss because of your business. In a fabrication shop that can include:

• A visitor or delivery driver injured on site
• Work done at a customer's site, such as measuring or installation
• A part you supplied failing in use and causing damage or injury
• Damage caused during delivery

Check what your policy covers for parts you make to a customer's drawing, and for work you subcontract to someone else, such as powder coating.

Customer materials and property

Shops often hold customer-supplied material, part-finished assemblies and parts waiting for collection. If a fire or theft destroys them, you may be liable.

Many general business policies don't automatically cover goods that belong to someone else. Ask your insurer how customer property is treated and whether you need to declare its value. Clear job records help here. If you know what was on site, whose it was and what it was worth, a claim is much easier to support.

Business interruption insurance

Business interruption cover keeps the business alive after an insured event. Your rent, loan repayments and wages continue whether or not the building has burnt down.

Claims are usually assessed on the margin you would have earned: what each job contributes after direct costs, which pays your overheads. Insurers call it gross profit in the UK and Australia, and business income in the US. So insure for the margin you need to cover fixed costs while you rebuild, and allow enough time to get machines replaced and running.

Part of recovery is getting your records back. When quotes, drawings and customer details lived in filing cabinets, a fire could wipe them out. Cloud systems have made that much easier. You still need to check that your quoting, job and accounting records are stored somewhere a fire can't reach.

Insurance for small machine shops

Small shops feel insurance decisions more:

• One or two machines may carry the whole business, so a single breakdown stops everything
• Cash reserves are thinner, so the deductible (excess) and the wait for a claim hurt more
• There's often no in-house engineer or spare parts
• The owner is usually also the estimator, operator and bookkeeper

For a small shop, business interruption cover and a plan for critical spares deserve as much attention as the property policy. For scale, one Tempus Tools customer running a small single-laser shop in Australia pays A$1,500 to A$2,000 a month for insurance, excluding workers' compensation.

Review your insurance once a year

Treat insurance as an annual business review, not an automatic renewal. A practical rhythm:

1. Start six weeks before your policy renewal.
2. Look back at the year: revenue, contribution margin, what you bought and sold, and any incidents.
3. Project the next year: new machines, more staff, new processes, different materials.
4. Update the insured value of every machine to today's market value.
5. Set business interruption cover to match the margin and overheads you'll need to cover.

A clean claims history makes insurance easy to buy. Some businesses try to claim back their premium every year. As one shop owner put it, insurance is "just the cost of doing the job."

Questions to ask your insurer

• Are my machines insured at current value or replacement cost (new-for-old), and what does each cost?
• Does my policy cover equipment breakdown, or only external events?
• How is a business income or interruption claim calculated, and for how long will it pay?
• Is customer-supplied material covered while it's on my premises?
• What does product liability cover for parts made to a customer's drawing?
• Is there a coinsurance or average clause, and am I insured for enough to avoid it?
• Is subcontracted work, such as powder coating, covered?
• Are deliveries and goods in transit covered?
• What do you need to know about my extraction systems and the materials I cut?
• If I rent the building, what is my responsibility and what is the landlord's?

Keep job records organised

Insurance covers the cost after something goes wrong. Good records make recovery faster and claims easier to support.

When quotes, drawings, customer requirements and job details sit in one system, you know what was in progress, whose material was on site and what each job was worth. Tempus Tools keeps the whole job in the cloud, from the first RFQ and estimate through to production documents. Integrations pass the same information to your accounting system. See how it works for machine shops, fabrication shops and job shops.

Review your cover with a professional

Machine shop insurance protects you against the events that could close the business: fire, theft, injury claims and long stoppages. The right cover depends on your machines, your materials, your size and how well you can recover on your own. Review it every year, insure each machine at what it's really worth, and talk it through with a qualified broker.

Frequently asked questions

What is machine shop insurance?

It's the set of policies a machine or fabrication shop uses to protect itself. That usually includes property cover for buildings, machines and stock, general (public) and product liability, workers' compensation and business interruption. Some shops add equipment breakdown cover. The right mix depends on the shop, so set it with a qualified broker.

What types of insurance do machine shops need?

Most shops look at commercial property insurance, general (public) and product liability, workers' compensation or employers' liability, business interruption and vehicle insurance. Equipment breakdown cover is optional. Requirements vary by country, and cover for injured staff is compulsory for most employers in the US, UK and Australia.

Does machine shop insurance cover equipment breakdown?

Usually not. Property policies cover external events like fire, theft and storm damage. Mechanical or electrical failure needs separate equipment breakdown cover (machinery breakdown in the UK and Australia), which can pay for repairs and, depending on the policy, lost revenue while the machine is down.

Does machine shop insurance cover customer materials?

Not always. Many policies don't automatically cover goods that belong to someone else. Ask your insurer how customer-supplied material and parts are treated while they're on your premises, and whether you need to declare their value.

What is business interruption insurance for a machine shop?

It covers ongoing costs and lost margin while the shop can't trade after an insured event, such as a fire. In the US it's usually called business income cover. Claims are based on the margin you would have earned, so the cover should be enough to pay rent, wages and other fixed costs until you're running again.
