Security system installers insurance checklist: what a security system installer should carry

The security system installer insurance checklist

QUICK ANSWER

Security system installers usually carry general liability, workers' compensation and commercial auto. Alarm and security installers wire systems whose failure during a burglary or fire becomes a lawsuit, hold the codes and camera feeds of every client, and work under state alarm licences that require insurance. The client's vendor desk and the property manager ask for proof of each. The checklist below covers who asks and how to check what you have.

Who asks a security system installer for what

Who	What they usually want to see
Enterprise clients & vendor onboarding	General liability, professional or cyber liability, workers' compensation and often an umbrella
Property managers & HOAs	General liability with the manager and owner as additional insureds, and workers' compensation
Cities, counties & permits	General liability, auto and workers' compensation at the limits in the permit or contract

Each of them wants a certificate, and most want it again at every renewal. A live certificate link from the wallet shows today's coverage to every holder and tells them when it changes.

How to check what you already have

General liability declarations page. Three liability numbers matter: each occurrence, general aggregate and the products–completed operations aggregate. Then the forms list: blanket additional insured, waiver of subrogation and primary and non-contributory wording satisfy every contract; scheduled forms satisfy one.
Workers' compensation information page. Item 3.A must list every state you work in, item 4 must carry the right class codes, and the employers' liability limits should meet what contracts ask. Check that the estimated payroll is close to this year's.
Auto schedule. Every vehicle listed with the right garaging address and use; symbols that include hired and non-owned auto; physical damage with the lender as loss payee where the vehicle is financed.
Equipment schedule. Owned items scheduled above the per-item threshold, a blanket limit for small tools, leased or rented equipment included, and the valuation (replacement cost or actual cash value).
Umbrella schedule of underlying insurance. Each primary policy listed with the limits the umbrella expects; a gap between the two is uninsured.
Professional liability declarations. Claims-made or occurrence, the retroactive date (it should not have moved), the limit per claim and aggregate, the deductible, and whether defence costs sit inside or outside the limit.
Cyber declarations. The headline limit matters less than the sublimits: social engineering, funds-transfer fraud, ransomware and business interruption, plus the regulatory coverage and the panel of breach vendors.
Bonds. The obligee (board, municipality or owner), the penal sum and the expiry date; a bond is renewed with the licence or the job, not with the policy year.
Hired and non-owned auto. Look for the symbols 8 and 9 or an endorsement by that name on the auto or general liability policy; without it, staff in their own cars are uninsured on company business.
Technology E&O declarations. The retroactive date, whether cyber coverages are included in the same form, contractual liability wording and the exclusions for guarantees of uptime.

What usually goes wrong for security system installers

A failure-to-perform claim after a break-in, excluded by general liability and never insured by E&O.
Client access codes and camera credentials held without cyber coverage.
Damage to the exact thing you are working on is excluded on most general liability forms; installation floaters and care, custody and control endorsements fill that hole.
A completed-operations aggregate quietly limited by endorsement; the declarations page looks fine until the forms are read.
Theft from a locked truck overnight with no tools floater, or a per-item limit lower than the one tool that mattered.
A personal auto policy on a truck with the company name on the door.

What underwriters will ask a security system installer

Residential versus commercial share, whether the business monitors systems or only installs, and the contract's limitation-of-liability wording
Residential versus commercial split of the work
Whether any work is done above three stories or below grade
Years of completed-operations coverage with no gap
Whether you warranty your work and for how long
Total value of hand and power tools kept on the trucks

Have the answers in the wallet before the renewal and the quote request fills itself in; CoverMatch sends one application to every eligible carrier and lines the quotes up against what you have.

Renewal timing

Audits at year end compare payroll, receipts and subcontractor costs with the estimate, so keep the wallet's size figures and the subcontractor certificates current. Start comparing sixty days before expiration, and ask for the limits the next contract will need rather than the ones the last one did.

Questions people actually ask

The alarm did not trigger during a burglary and the client is suing. Which policy?

Errors and omissions written for alarm companies, because general liability covers injury and property damage, not a system that failed to do its job. The contract's limitation-of-liability clause matters as much as the policy; carriers that write alarm E&O ask to see it.

Do we need cyber coverage as an installer?

You hold the keys to clients' buildings in digital form: codes, remote access and video. A breach is their breach, and vendor-onboarding questionnaires from commercial clients now ask for cyber limits alongside the liability certificate.

Does general liability cover damage to a customer's property while I work on it?

It covers damage to the rest of their property, not usually the part in your hands. Many forms exclude property in your care, custody or control, so a security system installer that handles valuable items or systems needs an endorsement or an installation floater. The policy explainer in the wallet flags the exclusion when it reads your policy.

A job I finished two years ago just caused damage. Which policy pays?

The general liability policy in force when the damage happens, as long as it still includes completed operations and you kept the coverage continuous. A gap or a switch to a form that excludes completed operations is how a security system installer ends up uninsured for old work.

Are tools stolen from my truck covered?

Under a tools floater, yes, subject to the deductible and any per-item limit. Under the commercial auto policy, no: auto covers the vehicle, not what was in it.
