An honest look at the pros, cons, and when it actually makes sense to use an agency—with real numbers, not sales pitches.
If you're short on time, here's the summary: recruitment agencies are worth using when you need to hire quickly, don't have an internal recruitment function, or are filling specialist or high-volume roles. They cost more than doing it yourself, but the time saved and reduced risk of a bad hire usually outweigh the fee.
The longer answer depends on your situation. Let's look at the real benefits and drawbacks.
This is the biggest advantage. For temporary and industrial roles, agencies can supply pre-vetted workers within 24–72 hours. Direct hiring for the same roles typically takes 4–8 weeks when you factor in writing the ad, posting it, screening applicants, interviewing, and processing offers.
For permanent placements, agencies typically fill industrial roles in 2–4 weeks vs the UK average of 27.5 days for direct hiring. That gap widens for specialist or hard-to-fill positions.
A single job ad for a warehouse operative on Indeed can generate 50–200+ applications within the first week. Without a system for filtering, someone in your team has to review every one of those manually.
Agencies do this for you. A typical industrial agency will screen 50–100+ applicants to produce a shortlist of 3–5 candidates for a permanent role. For temp positions, they draw from a pre-vetted pool of registered workers.
That screening typically includes:
An estimated 70% of the workforce are passive candidates—not actively looking, but open to the right opportunity. For blue-collar roles where LinkedIn usage is low, agencies are often the only way to reach these people.
Good agencies maintain databases of hundreds or thousands of pre-vetted, locally based candidates ready to work at short notice. They also advertise across multiple job boards simultaneously (Indeed, Reed, Totaljobs, CV-Library, sector-specific boards), giving far broader reach than a single employer posting one ad.
The REC estimates that a bad hire at mid-manager level costs over £132,000. For operative-level roles, the CIPD puts the average cost of labour turnover at £6,125 per leaver—covering recruitment, training, and lost productivity during the ramp-up.
Agencies reduce this risk because they've already screened for reliability, skills, and suitability. And if a permanent hire doesn't work out, most agencies offer a free replacement or rebate within the first 8–12 weeks.
Seasonal demand is a reality in warehousing, logistics, and manufacturing. Christmas, Black Friday, Easter, summer sales—these periods can require doubling or tripling your workforce for a few weeks.
With agency temps, you can scale from 10 to 100+ workers within days, then scale back down when demand drops—without redundancy obligations, because the agency is the employer, not you.
Employment law is complicated, and getting it wrong is expensive. Agencies handle:
Agencies process thousands of placements per year. They know what competitors are paying, what candidates expect, and where the talent shortages are. This stops you from either overpaying (wasting budget) or underpaying (failing to attract anyone and extending your time-to-fill).
Most industrial recruitment operates on a contingency basis—you only pay if you hire someone the agency introduced. There's no upfront cost, no retainer, and no risk. If the agency can't find the right person, it costs you nothing.
This is the most obvious downside. Permanent placement fees are typically 15–25% of annual salary. For a warehouse supervisor at £28,000, that's £4,200–£7,000. For an HGV driver at £38,000, it's £5,700–£9,500.
Temporary worker charge rates include the agency's margin on top of the worker's pay, typically 15–22% of the charge rate for industrial roles. Over the course of a long-term temp assignment, this adds up.
That said, when you factor in the hidden costs of direct hiring—job board ads (£200–£500 each), management time, failed hires—agency fees can represent reasonable value. It depends on your volume and situation.
If you're spending more than approximately £40,000–£50,000 per year on agency fees, it may be more cost-effective to hire an in-house recruiter (salary £25,000–£35,000 for a recruitment coordinator in the industrial sector). That one hire could save you the equivalent in agency fees.
The agency does the initial screening, which means you're trusting their judgement on who to shortlist. You may miss candidates who don't tick every box on paper but would be great in practice.
Communication can also get filtered through the recruiter rather than being direct, which sometimes leads to candidates hearing a slightly different version of the role than what you intended.
An agency recruiter may understand the skills required but not your workplace culture. They might send a technically qualified candidate who doesn't fit the team. This is more of a risk with transactional, one-off placements than with agencies you've built a relationship with over time.
There are roughly 30,000 recruitment agencies in the UK. Quality varies enormously. Common complaints about poor agencies include sending irrelevant CVs to hit internal targets, not properly briefing candidates about the role, and going quiet after placement.
The difference between a good agency and a bad one is significant. A good one saves you time and delivers strong candidates. A bad one wastes your time and sends you the same candidates you'd find yourself on Indeed.
Temp workers sourced through agencies can have higher turnover rates than permanent staff. In industrial sectors, temp turnover rates of 30–50% per year are not uncommon. Some temp workers are registered with multiple agencies and will leave for a slightly higher rate elsewhere.
This isn't entirely the agency's fault—it's partly inherent to temporary work. But it does create a cycle of constant retraining and reduced productivity if not managed well.
If you use agencies for every hire, you can lose the capability and knowledge to recruit directly. This makes you dependent on external suppliers and the fees that come with them.
An agency is likely the right choice if any of these apply to you:
| Situation | Why an agency helps |
|---|---|
| Volume or seasonal hiring (10+ roles) | Agencies have candidate pools ready to deploy. Screening 50+ candidates internally is a full-time job. |
| Urgent vacancies (need someone this week) | Agencies can supply pre-vetted workers within 24–48 hours. Direct hiring takes weeks. |
| No internal HR or recruitment team | If you don't have a dedicated recruiter, someone else is doing it badly alongside their actual job. |
| Specialist or hard-to-fill roles | HGV drivers, CNC operators, FLT reach truck drivers—specialist agencies have pools of qualified candidates that job boards don't reach. |
| Temp or flexible workforce needs | Agencies handle all employment admin. You can scale up and down without redundancy risk. |
| Compliance-heavy requirements | DBS checks, licence verification, right-to-work—agencies have established processes. |
| Cover for absence | Maternity, long-term sick, sudden departures—agencies can provide immediate replacements. |
Direct hiring may be the better option if:
Many businesses use a mix of both. They handle straightforward, low-volume hiring directly and use agencies for urgent, specialist, or high-volume needs. This keeps costs down while still having access to agency support when you need it most.
Don't just send a job description. Tell the agency about the working environment, shift patterns, physical demands, team dynamics, and why previous people left. Be specific about what's essential vs what's nice to have. "Must have FLT licence AND 5 years' warehouse experience AND CSCS AND own transport" when you'd actually accept someone with a good attitude and an FLT licence unnecessarily narrows the pool.
Good candidates in the industrial sector are off the market within 48–72 hours. If you take a week to review CVs, the best ones will have accepted other offers. Tell the agency quickly and specifically what you liked or didn't like about each candidate—"not suitable" is useless; "too senior, we need someone happy doing physical work long-term" is actionable.
Invite the agency to visit your site. Let them meet the team and understand the operation. A recruiter who has walked your warehouse floor will send better candidates than one who has only read a job description.
Using 5 different agencies and playing them off against each other may feel like good business, but it often results in all 5 sending the same candidates from the same job boards. Working with 1–2 preferred suppliers and giving them your loyalty means they prioritise your vacancies.
Giving an agency exclusive rights to fill a role (even just for 2 weeks before opening to others) means they invest more time because the fee is guaranteed if they deliver. Many agencies offer reduced fees for exclusivity—for example, 12% exclusive vs 15% non-exclusive.
The market sets the rate, not your budget. If warehouse operatives in your area are earning £13.50/hr and you want to pay £12.21, you'll struggle regardless of which agency you use. Be open to the agency's market intelligence—they see thousands of placements and know what candidates expect.
