At 25 employees, a fire protection company sits in an uncomfortable middle ground. You’re big enough that workers’ comp costs, OSHA compliance, and payroll complexity are genuine operational burdens. But you’re small enough that insurance carriers either don’t want your business or price you like you’re a liability waiting to happen.
Fire protection work — sprinkler installation, alarm systems, suppression system maintenance, fire extinguisher servicing — carries elevated risk classifications. That makes affordable coverage a real headache, not a theoretical one. A PEO can address several of these problems at once: pooling your employees into a larger group for better insurance rates, handling OSHA recordkeeping, and managing certified payroll when you land prevailing wage jobs.
The problem is that not every PEO understands fire protection. Many will treat you like a generic construction account, mislabel your class codes, and hand you a compliance binder and call it safety support. At 25 heads, the wrong PEO can cost you more than going it alone.
These seven strategies are built specifically for a 25-person fire protection operation. They’ll help you cut through the sales pitch and evaluate providers on what actually matters for your work.
1. Verify the PEO Has Real Experience with Fire Protection NCCI Codes
The Challenge It Solves
Fire protection work falls under specific NCCI workers’ compensation class codes — most notably 5183 for automatic sprinkler installation, with related codes covering fire alarm and suppression system work. These codes carry elevated base rates compared to general commercial construction. If a PEO lumps your workforce into a generic construction or plumbing category, you’re either overpaying or you’re underinsured. Both outcomes are bad.
The Strategy Explained
Before you get into pricing conversations, ask the PEO directly: which NCCI class codes do you currently manage for fire protection accounts? A provider that handles fire protection regularly will answer without hesitation. One that doesn’t will give you a vague answer about “construction trades” and pivot to their benefits package.
This matters beyond just compliance. Accurate code assignment directly affects your workers’ comp accounting and premium. If your installers are being coded under a lower-hazard category, that might look like a good deal until an audit reclassifies them and you owe back premiums. Conversely, if you’re being coded too broadly, you’re overpaying from day one.
Implementation Steps
1. Ask the PEO to list the specific NCCI class codes they’ll use for your workforce by job function — installers, service techs, office staff, and supervisors should each have distinct assignments.
2. Cross-reference those codes against your current standalone policy or your state’s workers’ comp bureau rate filings to verify they’re accurate and competitive.
3. Request references from other fire protection or mechanical contractor clients in their current book of business — not just “construction” clients generally.
Pro Tips
If the PEO can’t tell you the specific class codes they’d assign before you sign, that’s a red flag. A provider that manages fire protection accounts regularly will have this conversation fluently. If they’re learning alongside you, you’re their experiment — not their client.
2. Audit How Workers’ Comp Premiums Are Actually Calculated at Your Headcount
The Challenge It Solves
PEO workers’ comp pricing is often presented as a single blended rate, which makes it easy to accept without fully understanding what’s inside it. At 25 employees, you likely have an experience modification rate (EMR) that meaningfully affects your standalone premium. The question is whether the PEO’s blended rate is actually better — or whether you’re subsidizing worse accounts in their pool.
The Strategy Explained
Ask the PEO to break down their workers’ comp cost structure. You want to understand the base rate by class code, how the blended pool rate is calculated, and whether your EMR has any influence on what you pay. Some PEOs offer EMR-sensitive pricing for accounts your size; others use a flat pool rate that benefits high-EMR companies and disadvantages low-EMR ones. Understanding how high insurance mod rates interact with PEO pricing is critical here.
At 25 employees, you’re also generating enough annual payroll to have a real EMR history. If your loss history is clean, you may be better served by a standalone policy where your EMR directly rewards you. If your loss history is rough, the PEO pool may offer relief — but you need to do the math explicitly, not assume.
Implementation Steps
1. Pull your current workers’ comp policy declarations page and identify your current rate per $100 of payroll by class code, your EMR, and your annual premium.
2. Ask each PEO for their workers’ comp rate per $100 of payroll for your specific class codes, and whether that rate is fixed or subject to pool adjustments at renewal.
3. Build a simple comparison: current annual premium vs. projected PEO workers’ comp cost based on your actual payroll figures — not their estimate.
Pro Tips
Watch for PEOs that quote workers’ comp costs as a percentage of their administrative fee rather than as a standalone line item. That bundled presentation makes it harder to compare. Push for an itemized cost breakdown. If they resist, that’s telling you something.
3. Confirm the PEO Can Handle Prevailing Wage and Certified Payroll
The Challenge It Solves
Fire protection contractors regularly work on government-funded projects subject to the Davis-Bacon Act at the federal level, or equivalent prevailing wage laws at the state level. These jobs require certified payroll reporting using WH-347 forms (or state equivalents), dual-rate tracking when employees work on both prevailing wage and standard jobs in the same period, and fringe benefit calculations that don’t always map cleanly onto standard payroll structures.
The Strategy Explained
Not all PEO payroll platforms are built for this. Many are designed for straightforward salaried or hourly workforces in office or retail environments. When you run certified payroll through a system that wasn’t designed for it, you get manual workarounds, reporting errors, and potential payroll tax penalty exposure on government contracts you can’t afford to lose.
Ask the PEO specifically whether their platform supports WH-347 generation natively, or whether certified payroll is a manual process handled by their team. Also ask how they handle dual-rate weeks — when an employee works prevailing wage hours on Monday through Wednesday and standard hours Thursday through Friday. That scenario trips up a lot of platforms.
Implementation Steps
1. Bring a real certified payroll scenario from a recent project and ask the PEO to walk you through how their system would handle it — not in theory, but step by step.
2. Ask whether fringe benefit credits (health insurance, retirement contributions) can be applied against prevailing wage fringe requirements and how that’s documented in their system.
3. Confirm who is responsible for certified payroll compliance if an error occurs — the PEO or your company — and get that in writing.
Pro Tips
If a PEO rep has never heard of WH-347 or needs to “check with their team” on dual-rate tracking, you’ve already learned what you need to know. This isn’t an obscure edge case for fire protection contractors — it’s a routine part of the work.
4. Evaluate OSHA and Safety Program Support for High-Hazard Work
The Challenge It Solves
Fire protection installation falls under OSHA’s construction standards (29 CFR 1926), which means you’re dealing with fall protection, confined space entry, hazard communication, and potentially silica exposure depending on the work environment. At 25 employees, you probably don’t have a dedicated safety officer. The PEO’s safety support either fills that gap meaningfully or it doesn’t.
The Strategy Explained
Most PEOs offer some version of “safety resources” — usually a library of generic toolbox talks, a handbook template, and access to an 800 number. That’s not the same as substantive support for a high-hazard trade. What you actually need is help developing site-specific safety plans for different job types, incident investigation support when something goes wrong, and someone who understands the specific hazards in sprinkler and suppression system work.
Ask the PEO what their safety team’s background is. Are they generalists with HR backgrounds, or do they have actual construction safety credentials? A strong PEO for risk mitigation will have safety professionals who understand trade-specific hazards, not just generic compliance checklists.
Implementation Steps
1. Request a sample of their toolbox talk library and filter for content relevant to fire protection work — fall protection during overhead installation, chemical handling for suppression agents, working in occupied buildings.
2. Ask how they handle OSHA recordkeeping (300 log maintenance) and whether that’s managed by their team or handed back to you with a template.
3. Ask what happens if you receive an OSHA inspection or citation — do they provide representation support, or does that fall entirely on you?
Pro Tips
A PEO that can’t describe the specific hazards in fire protection installation work during a sales conversation probably can’t support you when something actually goes wrong on a job site. Push past the brochure language and ask specific questions. The quality of their answers tells you more than any feature list.
5. Stress-Test the Benefits Package Against What Your Workforce Actually Needs
The Challenge It Solves
One of the most common reasons small companies consider a PEO is access to better health insurance. But here’s something worth knowing at 25 employees: in most states, you already have access to the small group market, which covers employers with 1-50 employees and offers guaranteed-issue group plans. You don’t need a PEO to get group health coverage. The question is whether the PEO’s pooled plan is actually better than what you can get independently.
The Strategy Explained
Get a current small group market quote for your workforce before you evaluate any PEO’s benefits offering. That gives you a real baseline. Then compare the PEO’s plan options on network coverage, premium costs, deductibles, and out-of-pocket maximums — not just the monthly premium headline number. Companies approaching the 50-employee threshold face different dynamics, but at 25 you still have meaningful leverage in the small group market.
For a trade workforce doing physical labor, network access matters differently than it does for an office team. Are the hospitals and orthopedic specialists your employees are likely to need in-network? Repetitive stress injuries, back problems, and hand injuries are common in installation work. A narrow network that saves money on paper can create real problems when an employee needs a specialist referral.
Implementation Steps
1. Get a current small group market quote through an independent broker before talking to any PEO — this is your comparison baseline.
2. Ask the PEO for their full plan summary documents, not just a rate sheet — review deductibles, copays, network type (HMO vs. PPO), and out-of-pocket maximums.
3. Check network coverage in the geographic areas where your employees actually live, not just where your office is located.
Pro Tips
Don’t let a PEO use benefits as the primary justification for their fee if you can get comparable coverage independently. Benefits are one factor in the total value equation — not the whole equation. If their plan is genuinely better, great. But verify that independently rather than taking their word for it.
6. Negotiate Contract Terms That Protect a 25-Person Operation from Lock-In
The Challenge It Solves
At 25 employees, your headcount can shift meaningfully in a short period. You land a big contract and hire 10 people. You lose a contract and need to reduce. PEO contracts that were written for stable, predictable workforces can create real exposure when your headcount fluctuates — through minimum headcount penalties, annual fee commitments, or termination clauses that make exiting expensive.
The Strategy Explained
Read the termination clause carefully before you sign anything. Understand what happens if you need to exit mid-contract, reduce headcount significantly, or switch providers at renewal. Some PEOs charge fees equivalent to several months of service if you exit early. Others have automatic renewal provisions that lock you in unless you provide written notice 60-90 days before the contract anniversary.
Also ask about EMR data portability. Your experience modification rate belongs to your company, and you’ll need that data if you ever move to a standalone workers’ comp policy. Some PEOs make this data difficult to access when you leave. The same principles apply whether you’re evaluating a PEO for audit protection or general HR support — contract transparency matters.
Implementation Steps
1. Request a redlined contract draft before the final signing stage and have an attorney or HR advisor review the termination and renewal clauses specifically.
2. Ask explicitly: what are the financial penalties for early termination, and what triggers them? Get a plain-language answer, not a reference to section 14(b).
3. Confirm in writing that your workers’ comp loss run history and EMR data will be made available to you upon request at any point during or after the contract.
Pro Tips
Negotiate for a 30-day termination window rather than the 60-90 days many PEOs default to. At your headcount, you need flexibility. If the PEO won’t budge on termination terms at all, that tells you how they’ll handle disputes later. Flexibility in contract negotiation is usually a signal of how the relationship will go.
7. Run a True Cost Comparison Before You Commit
The Challenge It Solves
PEO pricing is presented in ways that make direct comparison difficult. Some charge a percentage of total payroll. Others charge a per-employee-per-month flat fee. Some bundle everything; others unbundle and add line items. Without a side-by-side analysis that accounts for all costs — including what you’re currently spending on HR administration, workers’ comp, benefits, and compliance — you can’t actually know whether a PEO saves you money at 25 employees.
The Strategy Explained
Build a complete cost model. On one side, your current total spend: workers’ comp premiums, health insurance premiums, payroll processing fees, HR software subscriptions, any outside compliance support, and a realistic estimate of internal time spent on HR and payroll tasks. On the other side, the PEO’s all-in cost including their administrative fee, workers’ comp through their program, and benefits premiums. A detailed PEO cost forecasting guide can help you structure this analysis properly.
Don’t forget soft costs. If you’re spending 10 hours a month managing payroll, certified payroll reporting, and OSHA recordkeeping yourself, that time has a value. A PEO that costs slightly more on paper but frees up meaningful owner or manager time can still be the right financial decision. But quantify it honestly rather than using soft costs to rationalize a bad deal.
Implementation Steps
1. Build a spreadsheet with two columns: current annual cost (workers’ comp, health insurance, payroll processing, HR admin tools, compliance support, internal time at an hourly rate) and projected PEO annual cost (all-in fee plus benefits premiums).
2. Get quotes from at least two or three PEOs so you have competitive pricing data — single-quote comparisons give one provider too much leverage.
3. Factor in transition costs: time to onboard employees to the new system, potential gaps in coverage during the transition period, and any fees from your current providers for early termination.
Pro Tips
If a PEO can’t give you an itemized cost breakdown that you can drop into a comparison spreadsheet, that’s a problem. Vague bundled pricing is designed to prevent comparison. Push for line-item transparency on workers’ comp rates, administrative fees, and benefits costs separately. Any provider confident in their pricing will accommodate that request.
Putting It All Together
Choosing a PEO for a 25-person fire protection company isn’t about finding the biggest name or the most polished sales deck. It’s about confirming the provider actually understands your class codes, can handle the payroll complexity of prevailing wage work, and offers safety support that goes beyond a generic binder.
Start with strategies 1 and 2. Verifying NCCI code experience and auditing workers’ comp pricing will eliminate most PEOs that aren’t a real fit — usually before you’ve spent much time in the evaluation process. From there, the certified payroll and safety support questions will further narrow the field to providers who actually understand trade contractor work.
The contract and cost comparison steps come last, but they’re where deals often go sideways. Don’t skip the termination clause review because you’re excited about the benefits package. And don’t let a compelling sales presentation substitute for a real side-by-side cost analysis.
If you want help running that comparison without starting from scratch, Don’t auto-renew. Make an informed, confident decision. PEO Metrics gives you an unbiased look at providers that actually work with fire protection contractors — with real pricing data and contract terms laid out clearly, so you’re not guessing.
