Yes. You can ask your umbrella insurer to raise the limit in the middle of the policy year. The higher limit then applies to every job you do for the rest of the term, including the contract that asked for it. You pay the extra premium only for the months left, and the insurer may ask a few questions about the job. At renewal you can keep the higher limit or drop back down. Who this is for: a contractor who already has an umbrella and just got a contract asking for more.
The short version
- An umbrella is a second layer of coverage that sits above your other liability policies, mainly general liability and auto. Its limit can be changed mid term.
- The increase is prorated. Six months left means you pay about half the yearly difference.
- The insurer reviews the increase before it agrees. Expect questions about the job, your payroll, and any new work.
- If your insurer caps the limit, a second insurer can add a layer on top for the rest of the term.
- Ask for the change in writing with an effective date before the certificate is due.
How does a mid term umbrella increase work?
An umbrella (also called excess liability) is a second layer of coverage that sits above your general liability, auto, and employers liability policies. The limit is set when the policy starts, but it is not locked. Your broker sends the insurer a request to raise it, with the contract that asks for more. The insurer reviews the request, quotes the extra premium for the months left, and issues an endorsement (a change to your policy, usually one extra page) with an effective date.
The new limit applies to all your work from that date forward, not just the one contract. It cannot be raised for a single job while the rest of your work stays at the old limit. See our commercial umbrella guide.
What will it cost to raise my limit mid term?
The insurer takes the difference between the yearly price of the new limit and the old one, then charges only the share for the months left. Figures below are illustrative for a small trade contractor with clean claims, and depend on trade, payroll, state, and claims.
| Change | Illustrative yearly price difference | Charged with 6 months left | Charged with 3 months left |
|---|---|---|---|
| $1,000,000 to $2,000,000 | $600 to $2,500 | $300 to $1,250 | $150 to $625 |
| $2,000,000 to $5,000,000 | $2,000 to $7,000 | $1,000 to $3,500 | $500 to $1,750 |
| $5,000,000 to $10,000,000 | $5,000 to $18,000 | $2,500 to $9,000 | $1,250 to $4,500 |
Specialty insurers and wholesalers sometimes add a flat endorsement fee, often $50 to $250 (illustrative). Standard insurers usually do not. A few insurers set a minimum charge for any mid term increase. Roofing, demolition, work at height, and New York work run higher than the table.
What will the insurer ask before it agrees?
- The contract. The insurer wants to see the job that needs the limit: what you are doing, where, for whom, and how big.
- Any change in your work. If the new job is a type of work you have not done before, or in a new state, say so. Hiding it can give the insurer grounds to deny a claim or cancel the policy.
- Payroll and subcontractor costs. A big job often means more payroll or more subs. The insurer prices for it.
- Underlying limits. Higher umbrella limits sometimes come with higher minimums underneath, for example $1,000,000 instead of $500,000 on employers liability (the part of workers comp that pays if an employee sues you).
- The date the certificate is due. That sets the effective date so the certificate can go out on time.
A clean account with a routine job is often approved in one to three business days. A new type of work or a hard trade can take a week or more.
What if my insurer will not raise the limit?
Insurers cap how much umbrella they will write for one business, often by trade. If yours says no, a second insurer can add a layer that sits on top of your umbrella for the rest of the term. It is written to follow your umbrella's terms, though it can add exclusions of its own, so your broker compares the two. Both layers show on your certificate of insurance (the one page summary of your policies). See what to do when your insurer caps the limit.
Should I drop the limit back down at renewal?
You can. Most contractors keep it, because the next general contractor asks for the same number and because a claim from the big job can show up after it ends. See whether you need an umbrella for one job or the year.
What this looks like in real life
Illustrative example. It is typical of what we see and is not a promise of how any specific situation would be handled.
The setup: A commercial glazing contractor in Arizona with ten employees carries a $2,000,000 umbrella that renews in March. In September, a general contractor's subcontract for a $480,000 curtain wall package on a medical office building asks for $5,000,000.
What went wrong: The owner assumes he must wait for renewal or buy a whole new policy. The certificate is due in nine days.
What it cost: The broker sent the contract and job details to the umbrella insurer, which raised the limit to $5,000,000 effective the next Monday. The yearly price difference was about $4,200, prorated to about $2,100 for the six months left, plus a small endorsement fee (illustrative). The certificate went out four business days later.
The fix: A mid term increase is usually the fastest and cheapest fix when you already have an umbrella. Send the contract to your broker the day it arrives.
Frequently asked questions
Q: Can I increase my umbrella limit for one contract?
Yes. Your umbrella insurer can raise the limit mid term, and the higher limit applies to all your work for the rest of the policy year, including that contract. You pay the extra premium for the months left, and the insurer may ask a few questions about the job.
Q: Can the higher limit apply only to that one job?
No. An umbrella covers your whole business, so a mid term increase raises the limit for every job from the effective date forward. That is usually a good thing, because other customers tend to ask for the same limit.
Q: How much does a mid term umbrella increase cost?
The yearly price difference between the two limits, prorated for the months left. Going from $1,000,000 to $2,000,000 with six months left often costs $300 to $1,250 (illustrative). Some insurers add a small endorsement fee or a minimum charge.
Q: How long does it take to raise my umbrella limit?
One to three business days for a clean account with a routine job. A new type of work, a hard trade, or a limit your insurer has not written for you before can take a week or more.
Q: Can I lower the limit again at renewal?
Yes. Most contractors keep the higher limit because the next customer asks for it and because damage from the big job can happen after the job ends. That is how the occurrence based policies most contractors carry work. If your general liability is claims made, ask your broker how the timing rule differs.
Q: Do I have to raise my other policy limits too?
Sometimes. A higher umbrella limit can come with higher minimums underneath, most often $1,000,000 instead of $500,000 on employers liability. Your broker will check before the increase is quoted.
