Most employers shopping around for OVO Talent alternatives are really asking one question: which agency will actually understand the role I'm hiring for? The seven below cover specialist tech recruiters, a few generalist firms with strong engineering desks, and one model that skips the agency fee altogether. Which one suits you depends on what you're hiring, how fast, and how much of the process you want to own. I've weighed each on industry focus, pricing model and candidate quality, because those are the three things that decide whether a recruiter earns their keep.
One caveat before the list. I haven't verified every agency's current fee card, and agencies change terms without telling anyone, so treat the pricing notes as the usual shape of each model, not a quote.
How an agency search actually runs
A new request comes in. You send a job description to the account manager, who passes it to a resource, usually a junior recruiter, who builds a longlist from the agency's CRM (Bullhorn is the system most of them live in) and from LinkedIn Recruiter. The recruiter screens by phone, writes a short candidate summary and sends two or three CVs to you. You interview. Feedback goes back through the same chain, which is where most delays happen.
That chain is the thing to evaluate. A good agency shortens it. A weak one adds a layer of people between you and the candidate who've never read a pull request.
The reason this matters for technical roles: a recruiter who can't tell a Terraform engineer from a general sysadmin will send you both and let you sort it out. You'll burn interview hours on mismatches, and your engineers will stop trusting the process after about the third one.

The seven agencies worth comparing
Specialist tech recruiters
Harvey Nash has long been a name in IT and digital hiring, with contract and permanent desks. Expect the standard contingency model, a percentage of first-year salary on a successful hire. Candidate quality is decent in enterprise IT, patchier at early-stage startups.
Hays Technology is the large generalist's tech arm. Big database, big reach, and a lot of competition between consultants for the same candidates. That's useful when you need volume and less useful when you need someone who'll hold a shortlist back for you.
Robert Walters runs specialist desks across technology and finance, and tends to suit mid-market firms that want a corporate-feeling process. Fees follow the contingency pattern, with retained options for senior searches.
Understanding Recruitment, Computer Futures and similar tech-focused firms sit in the same bracket: engineering-heavy consultants, quick turnaround on contract work, and a model where the best ones are worth the percentage and the worst are CV-forwarders.
Retained and executive search
For a Head of Engineering or CTO hire, contingency firms are the wrong tool. Retained search firms charge in stages (a portion upfront, a portion on shortlist, the balance on hire), and that structure forces them to commit research time. It's slower and costs more. For leadership roles it's usually worth it, because a bad hire at that level costs you a year.
Direct and platform hiring
The seventh option is to cut the agency out for some roles. Platforms like The Opportunity Hub let employers post roles and hire directly, and OHUB's approach to transparent recruitment pricing removes the percentage-of-salary uncertainty. It won't replace a retained search for a CTO. For mid-level engineers where your own team can screen, it's a sensible way to stop paying a fee on every hire.
What the pricing models really cost you
Contingency fees are typically a percentage of the candidate's first-year salary, paid only on success. Sounds fair. The catch is incentive: the agency gets paid by whoever places someone fastest, not whoever fits best.
Salary benchmarks help you check you're not overpaying a fee on an inflated offer. As a rough market observation, a mid-level backend engineer in London tends to sit somewhere around £60,000 to £80,000, and a senior around £85,000 to £110,000, with regional salaries (Manchester, Bristol, Leeds) noticeably lower for the same title. A percentage of those numbers adds up quickly across a scaling team.
Questions to put to any of them
Ask who will screen candidates and whether that person has ever written code. Ask what the rebate period is if a hire leaves in the first three months, and whether it's a full refund or a sliding scale. Ask how many of their placements in the last year were for roles like yours, and push back on vague answers.
Also ask for a sample shortlist summary. The quality of the write-up tells you more than the pitch deck: does it mention the candidate's actual stack and what they shipped, or just their job titles?
If you're hiring across several roles, CIPD publishes general guidance on recruitment practice that's worth reading before you sign a preferred supplier agreement. And check any agency's terms around candidate ownership, because the clause about who 'introduced' someone first causes more disputes than anything else.
Pick two agencies, give them the same brief, and compare what lands in your inbox after a week. That tells you more than any comparison list, including this one.
