How to Hire an Existing Construction Worker in Singapore: The Transfer Process Explained
If you want to hire a construction worker who's already working in Singapore, there are two ways to do it, and knowing both matters whether you're the one hiring or the one at risk of losing a worker. With the current employer's consent, a new employer can apply anytime, and the current employer has 7 days to approve it in the Ministry of Manpower's (MOM) myMOM Portal. Without consent, a new employer can only apply once the worker's Work Permit (WP) is 40 to 21 days from expiry. This guide walks through exactly how the transfer process works, who's responsible for what at each stage, and how to protect your own workforce if you're the current employer.
The Two Ways to Hire an Existing Construction Worker
With the current employer's consent, you can apply at any point during the worker's employment. Submit the Work Permit application the same way you would for any hire, and if the worker is eligible for transfer, the current employer receives an SMS or email notification. They then have 7 days to log in to myMOM Portal and approve or reject the request. If they don't respond in time, the application is rejected automatically.
Without the current employer's consent, you can only apply when the worker's Work Permit has between 40 and 21 days left before it expires. This is a fixed window, not a rolling one. Outside of it, you need the current employer's cooperation.
Either way, this specific process applies to workers from Non-Traditional Sources (NTS), North Asian Sources (NAS), or the People's Republic of China (PRC). Malaysian workers follow a different, simpler process, covered near the end of this guide.
If the Worker's Work Permit Has Under 14 Days Left
If the worker's current Work Permit has less than 14 days of validity remaining, you can't go straight to a standard application. You'll need to apply for pre-approval from MOM first, and the current employer will need to sign a consent form as part of that process. Once pre-approval is granted, the rest of the transfer proceeds as normal.
Who's Responsible for the Worker During a Transfer
A transfer isn't instant, and MOM sets out clearly who is on the hook for the worker's upkeep, maintenance and repatriation at each stage:
Current employer's Work Permit status | New employer's Work Permit status | Who's responsible | What happens next |
|---|---|---|---|
Live | Approved | Current employer | Both employers agree on the date to issue the new Work Permit. If hired without consent, the new employer must get the pass issued within 7 days after the current one expires. |
Live | In-Principle Approval (IPA) expired, withdrawn or cancelled | Current employer | Current employer may renew the Work Permit if eligible, or send the worker home. New employer takes no further action. |
Expired or cancelled | Approved | New employer | New employer must get the Work Permit issued promptly to avoid an overstaying fine. |
Expired | IPA withdrawn or cancelled before the old Work Permit expired | Current employer | Current employer may renew if eligible, or send the worker home. |
Expired | IPA withdrawn or cancelled after the old Work Permit expired | New employer | New employer must arrange to send the worker home. |
The key takeaway: responsibility stays with the current employer until the new Work Permit is actually approved and issued, not just applied for.
As the Current Employer: How to Keep Your Worker
Here's the part that catches employers off guard. Once a worker's Work Permit is 40 to 21 days from expiry, another employer can apply to hire them without asking you first. You'll be notified by SMS or email if this happens, and if the new employer's application is approved, you remain responsible for the worker (and for settling any outstanding salary) until the current Work Permit actually expires or is cancelled.
The single most effective defence is early renewal. As the current employer, you have priority to renew your worker's Work Permit, and the practical move is to renew the moment you receive the renewal notice rather than waiting. Waiting until the final few weeks is exactly the window where you're exposed to another employer's application.

What the New Employer Still Has to Arrange
Hiring an existing worker is faster than a fresh overseas hire, since there's no need for a Settling-in Programme or an overseas medical exam, but it isn't purely a paperwork handoff. As the new employer, you still need to:
Confirm your company is registered in the Contractors Registration System (CRS) with the Building and Construction Authority (BCA). This applies to any construction Work Permit application or renewal, regardless of the worker's nationality.
Check your Dependency Ratio Ceiling (DRC) headroom. You can employ up to 5 Work Permit holders for every local employee earning the Local Qualifying Salary (LQS), and at least 10% of your construction Work Permit holders must already be Higher-Skilled (R1) before you can hire or renew Basic-Skilled (R2) workers. Our DRC quota guide covers how to check this.
Buy a security bond, if the worker isn't Malaysian, and arrange medical insurance and Primary Care Plan (PCP) coverage, the same as you would for any new Work Permit.
Confirm the worker's safety course is still valid. A valid Construction Safety Orientation Course (CSOC) or equivalent certificate is required, and if you're planning a renewal down the line, it needs more than 1 month of validity left on the day of renewal. See our CSOC, SEC(K) and CoreTrade guide if you're unsure which certification your worker holds.
One Exception: Malaysian Workers Follow a Different Process
Everything above applies to workers from NTS, NAS, or PRC. If you're hiring an existing Malaysian Work Permit holder, the process is different and simpler: there's no 40-to-21-day no-consent window, no 7-day myMOM approval step, and no responsibility table to work through. Instead, the worker communicates their intention to leave their current employer, the current employer cancels the Work Permit (or it expires), and you apply fresh once that's done. Malaysian workers also don't require a security bond. If you're not sure which process applies to your situation, it's worth checking before you apply.
The Bottom Line
Hiring an existing construction worker in Singapore can be faster and cheaper than bringing in someone new, but it runs on a specific timeline with real consequences if you miss it, whether you're the one hiring or the one at risk of losing a worker. If you're currently employing workers with Work Permits approaching expiry, renewing early is the simplest way to protect your headcount. If you're looking to hire, knowing the 40-to-21-day window and the responsibility table above will save you from surprises partway through.
For a comparison of this process against renewing your own worker's Work Permit, see our Work Permit renewal guide. And if you're bringing in a worker from overseas for the first time rather than transferring an existing one, our step-by-step hiring guide covers that process instead.
