You post the job and wait. Weeks pass, the role is still empty, and your team is covering the gap.
If this sounds familiar, you are not alone. Slow hiring is common right now. In most cases, the problem is not a lack of good people. It is the recruitment process.
How Long Does It Take to Fill a Vacancy in the UK?
Adzuna’s UK Job Market Report shows the average time to fill a role was about 35 days in early 2026. The Totaljobs Hiring Trends Index says average time to hire has climbed to 12 weeks, up from 10 weeks in autumn 2025. The two reports measure different things, but both show the same trend. Hiring is getting slower. adzunatotaljobs
Why Your Vacancies Stay Open
The Skills Do Not Match
Skills mismatch is the biggest hiring challenge for employers, cited by 32%, according to the same Totaljobs research. Salary expectations come second. If your job advert asks for too much, or the pay does not fit the role, good candidates will not apply. totaljobs
Screening and Scheduling Take Too Long
Hiring managers are busy. CVs wait in an inbox. Interviews take days to book. Meanwhile, strong candidates accept other offers. Every day of delay gives your competitors a better chance.
The Process Is Unclear
When nobody owns each step, vacancies stall. Candidates also notice. Totaljobs says that right now, process is employer brand. How you hire shapes how people see your business. totaljobs
How to Fill Vacancies Faster
Start with a clear job brief. Agree the must-have skills, the salary range and the working pattern before you advertise.
Next, set a time limit for each stage. For example, review applications within two working days and book interviews within one. Reply to every candidate, even when the answer is no.
Finally, look at who does the admin. CV screening, phone screening and interview booking take hours. If your team does this on top of their main jobs, delays are almost certain.
When Outsourced Recruitment Support Can Help
You do not need to hand over your whole hiring process. Many businesses outsource only the tasks that slow them down. That could mean screening CVs, checking candidates, or booking interviews. Your team then spends time on what matters most: meeting the best people and making the final decision.
This is the idea behind ACS Smart Sourcing. It gives you extra recruitment support when you need it, without the cost of a bigger HR team.

Frequently Asked Questions
Have Question? We are here to help
What is the difference between time to hire and time to fill?
How can I speed up hiring without lowering quality?
Set clear stage deadlines, write a precise job brief and reply to candidates quickly. Fast does not have to mean careless.
Which recruitment tasks are easiest to outsource?
CV screening, first-stage phone calls and interview scheduling are common choices because they take time but follow a clear pattern.
Can I outsource just part of my recruitment?
Yes. You can keep control of final interviews and job offers while someone else handles the admin.
Why do good candidates drop out during hiring?
Strong candidates often have more than one option. Slow replies, long gaps between interviews and unclear next steps make them lose interest, so keeping in regular contact helps you hold on to them.
How do I know where my hiring process is slow?
Track how many days each stage takes, from advert to application review, interview and offer. The stage with the longest wait is usually where you should start fixing things. The Factorial guide explains how to calculate these numbers.
