24 Hours At Your Service
If you're on your housing society's managing committee and you've started collecting quotes for security guards, you've probably noticed something confusing: two agencies quote you wildly different numbers for what looks like the same service. Often, the difference isn't that one agency is cheaper - it's that they're quoting different shift structures without telling you.
This is one of the most common points of confusion we see when societies in Kolkata compare security agencies. Here's how the rate structure actually works, so you can compare quotes on equal footing.
Under Indian labour law, 8 hours is the standard working day. Any hours a guard works beyond that are legally classified as overtime, and overtime is capped at a maximum of 4 hours per day. This isn't an agency policy - it's the statutory framework every PSARA-licensed security agency has to operate within.
This one rule is the reason security guard quotations in Kolkata come in two distinct formats:
When an agency quotes you a "12-hour rate," what you're really being quoted is: 8-hour basic rate + 4-hour extra duty rate, combined into one number. Agencies that don't break this down for you aren't necessarily overcharging - but you can't tell whether their combined number is fair unless you see both parts separately.
Most housing societies in Kolkata run two-shift or three-shift coverage at the main gate - commonly a 12-hour day shift and a 12-hour night shift, or three 8-hour shifts. The shift structure you choose has a direct, and sometimes overlooked, impact on your monthly bill:
Two 12-hour shifts (2 guards/day) Each guard's daily cost = 8-hour basic rate + 4-hour extra duty rate. You're paying overtime rates for 8 of the 24 hours covered (4 hours × 2 guards), but you're managing only 2 guards, 2 shift handovers, and a simpler duty roster.
Three 8-hour shifts (3 guards/day) No overtime component at all - every hour is billed at the base rate. This is usually the lower per-hour cost, but you're now coordinating 3 guards, 3 shift handovers per day, and a more complex roster (which some managing committees find harder to supervise consistently, especially around the 2 AM–6 AM window when handovers are riskiest from a security standpoint).
Neither structure is universally "better" - it depends on your society's gate traffic patterns, whether you need double coverage during peak visitor hours (evenings, weekends), and how much roster complexity your committee wants to manage. A good agency will model both options for you rather than pushing one by default.
When you're comparing quotes from different agencies, ask each one to break down the following separately - not as one bundled number:
If an agency's quotation only shows you a single lump monthly figure with no breakdown, ask for the 8-hour and 4-hour components separately before you sign. It's a fair and standard request, and any properly licensed agency should be able to give it to you without hesitation.
Multiply the quoted 8-hour basic rate by 8, then check whether the extra-duty portion of a 12-hour quote works out to roughly proportional overtime pricing for the additional 4 hours - not a flat doubling, and not a rate that's lower than the basic hourly rate (which would suggest the agency is cutting corners somewhere, usually on PF/ESI compliance or on the guard's actual take-home pay, neither of which is good for the guard's reliability on your gate).
A security guard who's being paid correctly for overtime, with PF and ESI properly deposited, is a guard who's more likely to stay in the job, show up reliably, and take the role seriously. Underpriced quotes - the ones that look attractive on paper - are very often underpricing the guard's statutory dues, not the agency's margin. That shows up later as high guard turnover, inconsistent gate coverage, and a managing committee that's constantly training new guards on your society's protocols.
At Sterling Security Agency, every quotation for housing societies and gated communities in Kolkata is broken down by 8-hour basic rate and 4-hour extra duty component, with PF, ESI and supervisor visits itemized separately - so your managing committee can see exactly what you're paying for and compare it fairly against any other quote you've received.

Is a 12-hour guard shift legal in India?
Yes - provided the hours beyond the standard 8-hour working day are compensated as overtime, capped at 4 hours per day, in line with labour law. This is exactly how the 8-hour basic + 4-hour extra duty structure works.
Is 2-shift (12-hour) or 3-shift (8-hour) coverage cheaper for a housing society?
It depends on your guard count and gate traffic. Three 8-hour shifts avoid overtime pricing entirely but need 3 guards and more shift handovers; two 12-hour shifts need only 2 guards but include an overtime component. Ask your agency to quote both so you can compare the actual monthly totals for your specific site.
What should be included in a PSARA-licensed agency's quotation?
At minimum: basic rate, extra duty/overtime rate (if applicable), guard count, PF/ESI compliance costs, supervisor visit frequency, and replacement guarantee terms - each itemized, not bundled into one number.
