Read your current contract before you give notice
The first step in how to switch security companies is to open your existing agreement and find the exit terms, because they dictate your timeline. Look for the notice period required to cancel, whether the contract auto-renews and when that window falls, and any early-termination penalty. Many security contracts carry a thirty- or sixty-day notice requirement and an automatic renewal date; miss that date and you can be locked in for another term. Note the exact date your notice must be delivered and the method the contract requires, such as written notice to a specific address.
Also check what belongs to you when you leave. Your post orders, incident reports, activity logs, and any access credentials or equipment should transfer back to you, not disappear with the outgoing vendor. If the contract is silent, request these in writing before you announce the switch. Finally, review any clause about property, keys, or codes the current guards hold, since you will need to reclaim or rotate those the moment coverage changes hands. Reading the contract first turns a stressful exit into a scheduled one. If the terms are unclear, ask the current provider to confirm the notice date and any outstanding balance in writing, so you are not relying on memory or a sales promise when the deadline arrives. A five-minute contract review now prevents an accidental renewal or a penalty that quietly doubles the cost of leaving.

Line up the new provider before you end the old one
The cardinal rule of switching is never cancel first. Select and contract your new provider while the current one is still on post, so the handover overlaps rather than leaves a gap. Vet the incoming company the same way you would any new hire: confirm its state license, request a current certificate of insurance naming you as additional insured, verify that assigned officers are individually licensed, and call references at similar sites. A switch is a chance to fix whatever drove you out, so be specific about the failures you are leaving behind, whether no-shows, weak supervision, or surprise billing.
Give the new provider your real requirements up front: hours, posts, duties, risk windows, and any incidents that shaped your needs. Ask them to conduct a site walk before the start date and to draft fresh post orders, rather than copying the old ones blindly. This is also the moment to right-size coverage. Many buyers discover during a switch that they were overstaffed at quiet hours or thin at peak ones, so treat the transition as a chance to align staffing and cost with what your site actually needs.
Set a firm start date for the new team that begins before, or exactly as, the old contract ends. Confirm both companies in writing so nobody assumes the other is covering the overnight shift on changeover day.
Run the handover so coverage never drops
A clean transition is a scheduled overlap, not a single-day swap. Where possible, arrange for the incoming officers to shadow or overlap with the outgoing team for a shift or two, so site knowledge, patrol routes, access procedures, and known problem spots transfer to people rather than paperwork. If overlap is not possible, walk the new team through the site yourself before their first shift and hand them the post orders in person.
Security housekeeping matters most at the moment of change. Rotate or reclaim keys, change access codes, and revoke any credentials or system logins the previous guards held, on the day coverage transfers. Update your alarm company, front desk, and emergency contacts with the new provider's escalation numbers. Confirm the new team's reporting from day one so you can see activity logs and incident reports immediately and catch any early gaps.
| Handover step | Why it protects you |
| Overlap shifts | Transfers site knowledge to people, not just files |
| Rotate keys and codes | Closes access held by departing officers |
| Update escalation contacts | Keeps alarm and staff routing accurate |
| Confirm day-one reporting | Surfaces coverage gaps early |
Close out the old contract and avoid the same problems
Once the new team is established, close out the outgoing provider properly. Deliver your cancellation exactly as the contract requires, keep a dated copy, and confirm the final invoice matches the terms so a lingering notice period or early-termination charge does not surprise you. Reclaim any equipment, uniforms, or documentation the old company still holds, and confirm in writing that their officers' access has been fully revoked. A tidy exit prevents disputes and protects the reference you may want later.
Then make the switch count by fixing what went wrong. If the last provider failed on supervision, write field-supervisor visit expectations into the new agreement. If billing was the problem, insist the new contract defines what the bill rate includes and how rate changes are triggered and noticed. If no-shows drove you out, confirm the new provider's relief pool and escalation path in writing. Quoted ranges and terms vary by market and provider, so put every promise in the contract rather than trusting the sales conversation.
Switching security companies is not risky when it is sequenced: read the contract, hire before you fire, overlap the handover, secure access, and close out cleanly. Done in that order, your site stays covered throughout and you end up with a provider chosen to solve the exact problems that made you leave.
