A recruitment agency should not be the automatic answer to every vacancy. But it should not be the emergency service you call after six months of unsuccessful adverts and an exhausted hiring manager either.
As a 360-degree recruiter, I have spent years trying to work out that sensible point in the middle: when does bringing in a recruiter actually help the business?
The answer depends on what you need to solve. Sometimes you need access to a different candidate market. Sometimes you need time back. Sometimes you need somebody to tell you that the vacancy, as it stands, is unlikely to work. None of those is solved by simply ordering more CVs.
When you probably do not need an agency
If your own adverts regularly bring in suitable people, you understand the role and someone has time to run the process, direct recruitment may be perfectly sensible.
Your internal team, referrals or existing network might already be capable of finding the person. There is no virtue in paying an agency to make a straightforward job more expensive.
There is a perfectly reasonable exception: buying your own time back. We pay somebody to service the car, clean the windows or deliver the food shopping even when we could do those things ourselves. Recruitment can be a service you choose for the same reason.
Just be clear about what you are buying. Convenience, specialist search and help managing a difficult appointment are different needs.
When the vacancy needs a search you cannot resource
Some engineering and manufacturing roles draw on a narrow combination of technical knowledge, product experience, location and commercial understanding. Technical sales can be particularly awkward when the person needs both selling ability and enough knowledge to be credible with customers.
Before engaging an agency, ask whether somebody internally can identify and approach the relevant people. Do they have the time, tools and understanding to do it properly?
An agency can add value when that capability or capacity is missing. It should explain where it will look, how it will qualify interest and what feedback the business will receive.
The value is in doing the search and having useful conversations. It is not simply owning a database.
And the person who is already doing a similar job is not automatically the best appointment. Active applicants and people with transferable experience deserve proper consideration too.
When the same method has stopped producing useful results
If a vacancy has been advertised for weeks and the response is still wrong, decide when you will review the approach. Do not keep renewing the advert merely because you have already spent money on it.
There is a point where persistence becomes an expensive way of avoiding the discussion.
That discussion should cover the brief, salary, location, working arrangements and assessment process. It should also cover whether you are actually reaching the people you need.
A specialist recruiter should challenge the brief as well as work on it. “You are unlikely to fill this as it stands” may be more useful than another handful of introductions.
I have seen businesses get stuck in a cycle of interviewing the nearest available match, hoping it will work, then recruiting again. The answer is to understand what went wrong. An agency cannot rescue an unrealistic requirement just by agreeing to take it on.
When recruitment has become everybody’s extra job
Writing the advert, screening applications, arranging interviews and chasing decisions all take time. That work often lands with somebody who already has a full day planned.
An HR manager once said to me, while we were trying to arrange an interview, “I’ll do that after doing my day job.” I understand it. Recruitment becomes the B side of the working day.
The difficulty is that a candidate does not know which competing priorities have swallowed your afternoon. They just know they have heard nothing.
An agency can coordinate the search and keep things moving. But it cannot make the hiring manager available or approve an offer on the company’s behalf. If those decisions are the bottleneck, appointing a recruiter will not remove it.
Agree who owns each decision before you instruct the search.
When the commercial consequence justifies the support
A recruitment fee is visible. The cost of a vacancy drifting across the business often is not.
Look at the actual consequences: management time, cover, delayed work and pressure on the existing team. Then compare the scope and price of the proposed recruitment service with your realistic alternatives.
Do not assume the agency option will always be cheaper, or that its quoted fee buys a guaranteed result. Equally, do not describe the internal option as free if several people are spending time on it.
There is no universal salary percentage or fixed number of weeks at which every business should call a recruiter. A routine vacancy and a commercially important specialist appointment deserve different decisions.
When you need market feedback as well as candidates
A useful recruiter should tell you what the search is revealing. Are people rejecting the salary? Is the job title misleading? Is the location restricting the market? Does the required experience exist at the level you can afford?
That is information you can act on. Silence followed by the occasional CV is not much of a service.
I have long-standing clients who can send me a brief with relatively little explanation because I already know the business and have worked with them for years. That relationship has been built. It is not a reason to skip the conversation when we are starting from scratch.
Ask what the recruiter needs to understand and what they will report back. You should both know what problem the search is trying to solve.
Agree the service before you instruct it
Discuss the essentials and the things you can develop in a new hire. Agree the search approach, review points, candidate qualification and interview responsibilities.
Get clear on fees, what triggers them, payment and rebate terms, any exclusivity and what happens if the brief changes. Contingency and retained search describe commercial arrangements; instructing one agency or several is a separate decision.
I favour a focused relationship for a difficult specialist appointment. That needs accountability on both sides. “You are exclusive” should not mean “we will stop asking what is happening”.
Nor does adding more agencies automatically create a bigger market. If the search is struggling, understand the reason before adding another recruiter to the same conversation.
Use the pre-job creation checklist to get the brief ready. Part 3 of my recruitment process series explains how to work with an agency once you have decided to use one. For the company’s responsibilities during assessment, see the applications and interviews guide.
Make the decision before it becomes an emergency
You do not need an agency for every vacancy. You do need to recognise when your current resources or approach are not doing the job.
Bring in support when it has a defined purpose and a sensible commercial case. Then give the process the information and decisions it needs.
The question is not simply whether you can avoid an agency invoice. It is whether the route you have chosen is actually working for the business.
If you are weighing that up, the Employer Recruitment Pack will help you prepare the requirement. If you want my view on whether a specialist search makes sense, send me the outline of the vacancy. I would rather start with that conversation than pretend every job needs a recruiter.
