When most people think of job hunting, they picture hours scrolling through Indeed, Reed, or LinkedIn. But research shows that as many as 70 – 80% of jobs in the UK are never advertised publicly. This “hidden job market” is where the majority of opportunities lie, and if you’re not tapping into it, you’re missing out on some of the best roles available.
In this guide, we’ll explore why so many jobs go unposted, how UK employers really fill them, and practical strategies. You can use it to access these hidden opportunities.
Why So Many Jobs Stay Hidden
Companies don’t always post roles online for several reasons:
- Cost and speed: Job boards charge fees and slow the process. For urgent or niche hires, managers rely on referrals.
- Trust: Employers prefer candidates recommended by employees, clients, or partners—it reduces risk.
- Overwhelming demand: A single advert can attract hundreds of CVs. Internal moves and referrals cut through the noise.
- Discretion: Some roles replace current staff, involve sensitive projects, or relate to confidential expansion plans.
👉 CIPD research confirms these trends: UK employers often prefer internal promotions, referrals, or trusted agencies over advertising roles widely.
How UK Employers Actually Fill Hidden Jobs
According to the Chartered Institute of Personnel and Development (CIPD)the most common channels for unadvertised hiring are:
- Employee referrals: colleagues recommend trusted professionals.
- Internal promotions or redeployments: staff are moved before external hiring.
- Recruitment agencies: Hays, Michael Page, and Reed manage exclusive lists of unlisted roles.
- Specialist recruiters: agencies like Barclay Simpson focus on cyber security, risk, and compliance, giving candidates sector-specific access.
- Professional networks: industry events, trade associations, and alumni groups.

- Access before the crowd: hear about roles before they’re public.
- Less competition: often you’re one of a handful considered.
- Better fit: because opportunities arise through relationships, not mass applications.
