Use this checklist before you open the role, not after the first-choice candidate has vanished. Most backup plans fail because they get built in a panic, on day three of a hiring gap, by someone who's also trying to cover the vacancy. The practical answer to second talent alternatives is simple to state: line up three layers of fallback (a warm pipeline, an internal route, a contingent route) before you make the offer, and choose between them using one rule. If you need someone productive within a month, go contingent. If you can wait a quarter and the role is permanent, go to your pipeline or your own people.
That's the whole decision. The rest is making each layer real rather than theoretical.
Before the offer goes out
- Hold a ranked shortlist, not a single favourite. Keep your runner-up and third-placed candidate warm with a genuine "you were close, can we stay in touch" message the same week. Silence kills a backup candidate faster than a better offer elsewhere.
- Write down your walk-away points. Salary ceiling, start date, notice period, location. If you haven't agreed these with the hiring manager in advance, you'll lose days negotiating with yourself mid-crisis.
- Check notice periods on every finalist. A runner-up on three months' notice isn't a backup for a role that needs filling in six weeks. This gets overlooked constantly.
- Keep references and right-to-work checks moving for the runner-up. Running them in parallel costs a little admin. Running them from scratch costs a fortnight.

Building the talent pipeline you'll actually use
- Tag silver-medallists in your applicant tracking system with the reason they missed out. "Strong, but lacked X" is searchable in six months. "Rejected" isn't.
- Contact the pool on a schedule. A short note every few months beats a cold approach when you suddenly need them. A talent pipeline that only hears from you during a vacancy is just a mailing list.
- Look at referrals from your own team. The CIPD has long written about employee referral as a route to hires who settle in quickly, and in my experience it's the fastest warm source you've got.
- Use a video-first screen to widen the pool cheaply. Platforms like OHUB's video-first recruitment tools let you review a wider set of people without scheduling a dozen calls.
Internal mobility and contingent routes
- Ask who inside the business could do 70% of the job. An internal move leaves a smaller gap behind it, but it's still a gap, so check you can backfill. The earlier piece on internal talent marketplaces covers how to make this routine.
- Pre-agree a contingent workforce supplier. Contractors, interim staff and agency temps get you capacity in days, but you'll pay a premium and lose some institutional knowledge when they leave. Have rates and terms signed before you need them.
- Know your status rules for contractors. The off-payroll working rules (IR35) still catch UK engagers who assume a contractor is outside scope, so check status early. HMRC's guidance sits on Gov.uk.
- Consider an overseas contractor or employer of record for skills you can't find locally. It adds payroll and compliance work, and time zones matter, but for well-defined technical or support roles it widens your options sharply.
| Option | Speed | Cost | Main risk |
|---|---|---|---|
| Runner-up candidate | Fast if notice is short | Standard | Feels like second best, may drop out |
| Talent pool | Medium | Low | Stale contacts |
| Internal move | Medium | Low | Gap moves elsewhere |
| Contingent worker | Fastest | Highest | Knowledge walks out the door |
The item people skip
Someone has to own the fallback plan. Not "the team", one named person, with a date by which each layer must exist. Without that, the shortlist goes cold, the pool goes stale and the supplier agreement never gets signed.
Who owns yours?
