Process and timing
How do I handle staff selection in the UK?
Staff selection is the process of sifting, interviewing, and choosing the right person from your applicant pool. In the UK, it sits between recruitment (finding candidates) and hiring (making the offer). Done well, it uses a consistent, fair process to match skills and character to the role. Done poorly, it wastes time and leads to costly mis-hires.
Staff selection is the disciplined bit in the middle. You have a pool of applicants. Now you need to pick the right one.
It is not the same as recruitment. Recruitment is the work of attracting and sourcing candidates. Selection is the work of assessing them fairly and consistently. A sound selection process protects you from bad hires and from claims of unfair treatment.
The core steps of UK staff selection
Most UK employers follow a sequence like this:
- Sift the applications. Score every candidate against the same person specification. Reject anyone who does not meet the essential criteria.
- First interview. Usually a structured conversation with set questions. Every candidate gets the same questions in the same order.
- Second interview or assessment. This might be a practical task, a presentation, or a meeting with a wider team.
- Check and verify. Take up references. Confirm qualifications and the right to work in the UK.
- Decide and offer. Choose the candidate who best fits the role, not just the one you liked most.
What it costs to get wrong
A poor selection decision is expensive. The direct costs of a mis-hire at a £30,000 salary can easily top £15,000 once you factor in wasted salary, training, and management time. Our cost-of-vacancy calculator helps you model the real figure for your business.
Doing it yourself vs. using an agency
You can run selection entirely in-house. It costs you time, not a fee. That works if you have a strong HR function and a deep enough applicant pool.
If you use an agency, you are buying a pre-sifted shortlist. A good agency does the early selection work for you: screening against your brief, conducting first interviews, and presenting only candidates who meet your bar.
Our managed service, Premium Hire, follows a fixed-fee model. You pay one price agreed upfront, never a percentage of salary.
| Salary Band | Premium Hire Fee |
|---|---|
| Up to £30,000 | £1,500 +VAT |
| £30,000 – £44,999 | £2,000 +VAT |
| £45,000 – £59,999 | £3,000 +VAT |
| £60,000 – £79,999 | £4,000 +VAT |
We source, screen, and interview. You receive a shortlist of candidates who have already been assessed against your role. You then run your final-stage selection.
How long selection takes
Across 46 roles we have filled, the median time from brief to accepted offer was 42 days. The middle half of roles fell between 29 and 68 days. The fastest was 14 days; the slowest was 169.
Your own timeline depends on how many stages you build in and how quickly you can get decision-makers in a room.
Common selection methods and when to use them
| Method | Best for | Watch out for |
|---|---|---|
| Structured interview | Nearly every role | Unconscious bias if questions are not standardised |
| Work-sample test | Technical or practical roles | Can be time-consuming to design well |
| Presentation | Client-facing or strategic roles | Tests presentation skill more than day-to-day competence |
| Psychometric test | Roles requiring specific cognitive or behavioural traits | Must be properly validated; never use as the sole filter |
| Group exercise | Graduate or team-heavy roles | Favours the loudest, not necessarily the best |
Keeping it legal
UK selection must be fair and non-discriminatory under the Equality Act 2010. That means:
- Using the same scoring criteria for every candidate.
- Keeping a clear paper trail of why each person was rejected or progressed.
- Making reasonable adjustments for disabled candidates at every stage.
ACAS publishes free guidance on lawful selection. The GOV.UK employer guidance is also a sound starting point.
When to bring in outside help
You might handle selection yourself if you are hiring for a role you understand deeply and you have a strong internal process. You might pay for help if:
- You lack the time to sift and interview dozens of applicants.
- The role is senior or niche and you need a market map, not just a job-board response.
- You have had a mis-hire before and want a more rigorous front-end filter.

FAQs
What is the difference between recruitment and selection? Recruitment is the process of attracting and sourcing candidates. Selection is the process of assessing, interviewing, and choosing the right person from that pool.
How much does a mis-hire cost a UK business? The direct cost of a mis-hire at a £30,000 salary often exceeds £15,000 when you account for wasted salary, training, and management time. The figure rises sharply for senior roles.
Is it legal to use different selection methods for different candidates? No. To comply with the Equality Act 2010, you must apply the same scoring criteria and process to every candidate. You should make reasonable adjustments for disabled candidates, but the core assessment must be consistent.
