The right time to hire is when three things are true at once: there is consistent, repeatable work that somebody else could do, the business can carry the full cost with margin to spare, and you understand the role well enough to recruit for it properly. If any one of those is missing, the hire is a gamble rather than a decision — and the most expensive mistake is treating “can I afford the salary?” as the test, because the salary is roughly two-thirds of what the first year actually costs.
The wrong time is when you are drowning and hoping a new person will fix it. Drowning is usually a structural problem — pricing, process, scope, or work that should never have been taken on — and adding headcount to a structural problem gives you the same problem with a higher cost base and somebody to manage. This guide sets out the full cost, the revenue it has to cover, who to hire first, how to recruit so the interview predicts the job, and the four cheaper options worth ruling out before you commit.
What does a first hire actually cost?
Start with the arithmetic, because it changes the conversation.
An illustration, not a quotation — use your own figures, and get the exact employer National Insurance and pension amounts for your payroll from your accountant. Salary £28,000. Add employer National Insurance, pension and the cost of a desk, laptop, phone and software licences: on typical figures that is 20 to 25 per cent on top, so call it £34,500 fully loaded, or £2,875 a month. Recruitment: an agency fee at 15 per cent of salary is £4,200, or several days of your own time if you do it yourself. Then the ramp-up — nobody is fully productive on day one, so assume three months at partial output, which is roughly £5,000 of cost against reduced return. First-year cost is therefore closer to £43,000 than £28,000.
None of that is an argument against hiring. It is an argument against asking the wrong question. The free True Cost of a Hire calculator runs the same sum with your figures in about two minutes.
How much revenue does the hire need to cover?
At a 45 per cent gross margin, £34,500 of annual cost needs roughly £77,000 of additional revenue to cover it. Work that out with your own margin before you advertise, and write the number down — it is the number the hire has to earn, and it is usually larger than owners expect.
If the role does not generate revenue directly — an administrator, a coordinator, an operations person — then it has to release owner time that does. Be specific about that: if the role frees twelve hours a week and you put four of those into selling, four into pricing work properly and four into managing, that is the return you are underwriting. Write down which of the two it is before you write the advert, because a role that is quietly expected to do both usually does neither. If you cannot see the margin yet, understanding your numbers comes first.
Who should you hire first?
For most small businesses, the first hire should free the owner’s time for work only the owner can do. In practice that usually means somebody operational rather than another version of you: administration, scheduling, processing, coordination, and the delivery work currently filling your diary with things that do not need your judgement.
The instinct is often to hire another fee earner, because that feels like growth. Sometimes it is right. But if you are still doing eight hours a week of invoicing and diary management, a second fee earner adds work to the bottleneck rather than removing it — more delivery arriving at the same single point of approval. Work out where the queue actually forms before you decide what to buy; stop being the bottleneck is the diagnostic for that.
Why is the job description a thinking tool?
Writing the role down before you recruit is not bureaucracy; it is how you find out whether you actually know what you are buying. Write it around outcomes rather than attributes. What does success look like at 90 days, and at six months? What will this person own that nobody currently owns?
If you cannot answer those questions, you are not ready to recruit, and interviewing will not clarify it. It will simply mean you appoint whoever interviews best. Half an hour with a blank page saves you the far more expensive discovery, six months in, that the role was never really defined.
How do you run an interview that predicts the job?
Structured interviews beat conversation: the same questions, in the same order, for every candidate, aimed at the competencies the role genuinely needs. Unstructured interviews reliably favour people who are good at interviews over people who would be good at the job, and they favour candidates who remind you of yourself — which is how a business ends up with five people who share the same blind spot.
Ask about specifics rather than intentions. “Tell me about the last time a client was angry with you — what did you actually do?” produces evidence. “How do you handle difficult clients?” produces a rehearsed answer. And where you can, set a short, paid, realistic task: half a day of someone doing something close to the actual work tells you more than an hour of talking about it, and it tells the candidate something true about you as well.
How do you check references properly?
Most reference checks are a formality, which is why they catch nothing. A useful one asks about performance in situations similar to the ones the person will face with you: what they owned, how they handled pressure, what they were like to manage.
The most revealing question is the simplest one: “if you could have them back tomorrow, would you?” The answer matters, and so does the pause before it. Take two references, speak to people rather than exchanging emails where you can, and treat a reluctance to talk as information rather than an administrative obstacle.
Why does onboarding decide whether a good hire stays good?
A strong appointment can be turned into a weak one by a poor first month. The first 90 days set the expectations, relationships and habits that persist for years, and “we are too busy to onboard properly” simply moves the cost somewhere less visible.
Write the plan before they accept, not on their first morning: who they meet in week one, what they own by when, and a weekly half-hour with you for the first six weeks. Book the 30, 60 and 90-day reviews in the diary on day one. It is one of the cheapest high-return investments available to a small business, and it is the difference between a hire who is useful in six weeks and one who is still tentative at six months.
What are the cheaper alternatives to hiring?
Headcount is one answer to a capacity problem, and it is the most expensive and least reversible. Work through these four honestly first.
- Put prices up. If you are at capacity and turning work away, the market is telling you something. Higher prices reduce demand and raise margin at the same time, which is the exact opposite of what hiring does to your cost base.
- Stop doing the unprofitable work. Rank clients by gross profit and there is usually a bottom slice consuming disproportionate capacity. Releasing it can free more time than a new person would.
- Fix the process before adding people to it. Hiring into a broken process gives you a broken process running at twice the cost, and twice the frustration.
- Outsource a defined function. Bookkeeping, payroll, first-line support. No employment risk, and it scales down as easily as up.
If you have genuinely worked through all four and the work is still there, that is a far stronger basis for hiring than being busy — and you will recruit better for having done it.
What to do this week
- Prove the work is consistent: three months of evidence, not one busy fortnight.
- Cost the role fully — salary plus 20 to 25 per cent, plus recruitment, plus ramp-up.
- Work out the coverage: how much revenue at your gross margin, or how many owner hours released and what they will be used for.
- Write the 90-day and six-month outcomes before you write the advert.
- Fix the interview questions in advance and use the same ones for everyone.
- Design a practical task that resembles the real work, and pay for it.
- Take two references and ask the returning-employee question.
- Write the first-30-days plan before they accept.
- Book the 30, 60 and 90-day reviews in the diary on day one.
Four questions to sit with
- Is this a headcount problem or a structure problem — and what is the honest answer?
- Out of ten, how clearly could you describe what this person will own?
- What will you stop doing once they start, specifically and by name?
- If the hire does not work out, at what point will you accept that, and what will you do?
Hiring is the point at which an owner becomes a manager, and that is a different skill set entirely — briefing, standards, follow-up, difficult conversations. That transition is the core of Leadership Coaching, and building a team around your strengths is a good companion read before you write the advert.

Common questions
Should I hire part-time first?
Often, yes. Two or three days a week for an operational role reduces the risk, tests your own ability to delegate and can be scaled up as the work proves itself. It also suits a wider pool of good candidates than a full-time role does, particularly for experienced people who want fewer hours. The trap is expecting five days of output from three days of hours, which is how a sensible arrangement turns into a resentful one within a quarter. Define the outcomes for the days you are actually buying, and be honest with yourself when the work outgrows them rather than quietly stretching the person.
Should the first hire be a contractor or an employee?
It depends on the work, the control you need and the employment status rules, which are a matter for your accountant rather than a coaching guide — get that checked before you agree anything, because getting it wrong is expensive. Commercially, the distinction is simpler. Contractors suit defined projects, specialist skills and work with a clear end point, and they cost more per hour for a reason. Employees suit ongoing accountability, client relationships and anything where you need somebody to own an outcome over time rather than deliver a task. If you want the role to grow into something, that points to employment.
How long before I know whether it is working?
You will have a strong signal by 90 days if you set clear outcomes on day one and actually reviewed them at 30 and 60. Without those outcomes you will still be unsure at nine months, which is the far more common and much more expensive situation — and by then the doubt has usually spread to the rest of the team. Judge against what you wrote down, not against how you feel about the person. And separate the two questions that get tangled here: is the person capable, and did you define the role well enough for anyone to succeed in it?
What if I get it wrong?
Act early. The cost of a poor hire is almost entirely in the months spent hoping it improves, and every one of those months makes the conversation harder and the damage to the rest of the team greater. Handle it properly — there is a right process for managing performance and for ending employment, and taking advice on it is cheaper than getting it wrong. But do not let discomfort turn a three-month problem into a two-year one. Then do the post-mortem honestly: most poor hires were poorly defined before they were poorly appointed, and that part is yours to fix.
Do I hire ahead of the work, or wait until it is there?
Wait, in almost every case, and shorten the wait deliberately instead. Hiring ahead of the work means funding the full monthly cost — £2,875 in the illustration above — out of hope, which is the most expensive finance available to a small business. The exception is an evidenced pipeline: signed contracts, or a client who has confirmed in writing that volume rises on a date. A busy quarter is not that. If the fear is that waiting means turning work away, treat that as the problem to solve rather than the reason to hire — subcontract the overflow, raise prices on new enquiries, or accept the work on a longer lead time and be straight with the client. All three are reversible. A salary is not.
