AI for recruitment agencies: what to automate first, and what to leave alone.

Most agencies have a dozen places AI could help and no clear first step. Here is where the hours actually go in a UK agency, the three pilots we would start with, what we would never automate, and what the ICO expects if you use AI to screen candidates.

Short answer: start with the admin your consultants already resent, not the most impressive idea. In most UK recruitment agencies that means CRM records updated from call notes and weekly client reporting. Candidate shortlisting is the biggest prize, but it should come second, once your data is clean and your human review is properly set up.

Your clients and candidates already judge how modern your agency is. This is how you look like the agency that has it handled, without betting the budget on hype.

Where the hours go

These figures come from our worked example of an eighteen-person UK agency. The agency is a composite and the numbers are illustrative; a real audit measures your own workflows. The shape is what we see again and again.

The full ranking, with build costs and the reasoning, is in the worked example.

How an Ishigai engagement works: an AI Opportunity Audit from £750, then a 30-day pilot on one workflow from £2,500, then managed AI agents from £379 a month or a full handover. The audit fee is credited in full against a pilot started within 60 days.
Built to work. Better with Ishigai. Audit the opportunity, prove the value with a pilot, then put it to work. We can stay alongside you to optimise and improve it as your business grows, or hand it over when you're ready. Every stage is priced upfront.

Three pilots we'd start with

Each one is a 30-day pilot on a single workflow with one owner, measured before and after. Pilots start from £2,500.

Start where the data gets fixed. Everything smarter depends on it.

What we'd leave alone

AI screening and the ICO

The ICO's Recruitment rewired work drew on more than 30 employers between March 2025 and January 2026. Its main finding: many employers using automated recruitment are likely making solely automated decisions without meaningful human involvement. That brings UK GDPR's rules on automated decision-making into play and needs more safeguards than most had in place.

The ICO is not banning AI in hiring. It wants employers to be more transparent with candidates, to apply human involvement consistently to everyone at a given stage, and to monitor for fairness and bias. So when we build shortlisting, it ranks and explains, a consultant decides, and there's an audit trail from day one. We're not lawyers, and we'll flag where you need your own legal sign-off.

How to start. Run the free website report if you want something now with no call. If the problem is operational, the AI Opportunity Audit is from £750, takes one to two weeks, and is credited in full against a pilot started within 60 days.

Frequently asked questions

What should a recruitment agency automate first?

For most UK agencies, the safest first project is getting CRM records updated from consultants' call notes. It saves real hours, nothing goes in front of clients or candidates, and it fixes the data that every later project depends on.

Is it legal to use AI to screen CVs in the UK?

AI screening is not banned. The ICO's view is that many employers using automated recruitment are likely making solely automated decisions without meaningful human involvement, which brings UK GDPR rules on automated decision-making into play. Build it so a person genuinely reviews and decides, tell candidates how it works, and monitor for bias. Take your own legal advice for your specific setup.

How much does AI automation cost for a recruitment agency?

Ishigai's AI Opportunity Audit is from £750 and is credited in full against a pilot started within 60 days. Pilots on a single workflow start from £2,500, and larger builds across several systems typically run up to £15,000, fixed-price.

Do we need to replace our ATS or CRM?

No. We build on top of the ATS, CRM and inbox you already use. In most agencies the system isn't the bottleneck; the manual work either side of it is.
