When an organisation needs to hire, choosing the right recruitment model is as critical as choosing the right candidate. For mid-level roles, a quick influx of CVs might suffice. However, when hiring for the C-suite, a Director, or a highly specialised technical leader, the recruitment strategy must change.
The recruitment industry is broadly divided into two distinct models: Contingency and Retained Executive Search. Understanding the commercial and operational differences between them will dictate the quality of the candidates you ultimately see.
Here is a breakdown of how each model works, their pros and cons, and when to use them.
Contingency Recruitment
Contingency recruiters operate on a success-only basis. You only pay them if you hire one of their candidates. Because they are competing against your internal HR team and often other contingency agencies, their primary driver is speed.+1
How it Works: The agency searches their existing database, posts job adverts, and rapidly fires CVs across to the hiring manager. The goal is to be the first to introduce a viable candidate.
The Pros:
- Low Financial Risk: There are no upfront costs. If they do not fill the role, you do not pay a penny.
- Speed: Because it is a race, contingency recruiters will often provide a shortlist within 48 to 72 hours.
- Broad Reach: Engaging multiple agencies means your job advert gets pushed out across numerous platforms simultaneously.
The Cons:
- “CV Pushing”: Because they are not guaranteed a fee, contingency recruiters cannot afford to spend weeks deeply vetting a single candidate. You may receive high volumes of poorly matched CVs.
- Focus on Active Candidates: They rely heavily on people actively looking for work (those on job boards), missing out on the “passive” market of top performers who are currently happy in their roles.
- Lack of Commitment: If a role proves too difficult to fill, a contingency recruiter will simply stop working on it and move on to easier, more lucrative vacancies, often without telling you.
Best Used For: Mid-level management, junior roles, high-volume hiring, or roles where the skill set is abundant in the active market.
Retained Executive Search
Retained search (often called “headhunting”) is a dedicated, exclusive consulting engagement. You pay an upfront fee to retain the firm’s services, guaranteeing that they will fill the role. This model is built on thoroughness, not speed.+1
How it Works: Fees are typically paid in three instalments: one-third at the start (the retainer), one-third upon presentation of the shortlist, and the final third upon the candidate signing the contract. The search firm acts as an extension of your brand in the market.
The Pros:
- Access to the Passive Market: Search firms map the entire market. They do not rely on job adverts; they proactively approach top-tier executives who are employed by your competitors and persuade them to consider your opportunity.
- Deep Vetting and Exclusivity: Because they are guaranteed a fee, they invest heavily in behavioural profiling, rigorous interviewing, and deep referencing before you ever see a CV. You will receive a curated shortlist of 3 to 5 highly qualified candidates.
- Guaranteed Delivery: A retained firm commits to working on the mandate until the position is filled, regardless of how difficult the search becomes.
- Confidentiality: If you are replacing an underperforming executive who is still in the business, a retained firm can conduct the search with absolute discretion under Non-Disclosure Agreements (NDAs).
The Cons:
- Financial Commitment: You must pay an upfront fee before seeing any results, which requires trust in the search firm.
- Time-Consuming: A proper executive search takes time. Mapping the market, approaching passive candidates, and conducting initial interviews usually means it takes 4 to 8 weeks just to produce the shortlist.
Best Used For: C-suite appointments (CEO, CFO, COO), Board of Directors, highly sensitive replacements, and niche technical leadership roles where a bad hire would severely damage the business.
