How to hire your first employee as a tradesperson

Most sole traders wait far too long to hire their first person. They tell themselves they're not quite ready, that they'll hire once things calm down, or that the paperwork is too complicated. Meanwhile, they work 60-hour weeks, turn away profitable jobs, and run on empty. This guide explains when you're genuinely ready, what you legally need in place, how to find the right person, and how to set them up for success from day one.

Why most sole traders wait too long

The fear of hiring is understandable. You are adding a fixed cost — wages, employer's NI, insurance — to a business whose revenue fluctuates. You are also taking on legal and management responsibility for another person. Both are real risks. But the opportunity cost of staying solo is just as real and far less visible.

Every job you turn down is revenue going to a competitor. Every evening and weekend you work instead of hiring is time you are not spending on relationships, health, or the higher-value parts of your business. Sole traders who stay solo indefinitely often reach a ceiling of £80,000–£100,000 revenue per year — not because there isn't more demand, but because there aren't more hours in the day.

The decision to hire is not just a cost decision. It is a choice about what kind of business you want to run and how much of your own time you are willing to trade.

The real cost of staying solo

Consider a plumber who turns away an average of four jobs per month because he is fully booked. At £600 per job, that is £2,400 per month — or £28,800 per year — in declined revenue. An employed engineer on £35,000 costs roughly £40,000 once you add employer's NI. The maths, even before accounting for the additional growth that capacity enables, is compelling.

The less visible cost is what sustained overwork does to the quality of your work, your customer relationships, and your willingness to market the business. Tradespeople who are constantly exhausted stop chasing quotes, stop asking for reviews, and start doing the minimum rather than the best. That affects reputation and repeat business in ways that are slow to show up but hard to reverse.

When you're ready: the signals to watch for

Three concrete signals tell you it is time to hire:

• You are consistently turning down work. If this has happened every month for three months or more, demand genuinely exceeds your capacity. One or two turned-away jobs is a blip; a sustained pattern is a signal.
• You are regularly working evenings and weekends. This is a temporary coping strategy, not a sustainable operating model. If it has been going on for more than two or three months, a hire is overdue.
• You cannot take a holiday. If you cannot step away for a week without the business stopping entirely, you do not have a business — you have a job that is entirely dependent on you. A first hire is the beginning of fixing that.

The financial test is straightforward: can the additional revenue a second person generates cover their total cost of employment, with margin left over? For most trade businesses, the answer is yes well before the emotional readiness catches up.

Employed vs subcontractor: the HMRC test

Before you decide how to engage your first hire, you need to understand the difference between an employee and a subcontractor — and why getting this wrong is a serious legal risk.

HMRC uses an employment status test based on several factors. A worker is more likely to be considered an employee if: you control how and when they work; they cannot send a substitute in their place; they work exclusively or primarily for you; you provide their tools and equipment; and they are integrated into your business operations. If all of these apply, HMRC will treat the person as an employee regardless of what your contract says.

Using a subcontractor arrangement to avoid employer responsibilities when the working relationship looks like employment is known as false self-employment. HMRC actively investigates this in the construction sector via CIS compliance checks. If found guilty, you can be liable for unpaid employer's NI and income tax going back years, plus penalties and interest.

A genuine subcontractor sets their own hours, works for multiple clients, uses their own tools, invoices you for their work, and can send someone in their place. If your arrangement looks materially different from this, take employed status seriously.

What you legally need before your first employee starts

There is a set of legal and administrative requirements that must be in place before your employee's first day. None of them are complicated, but all of them are mandatory:

• PAYE registration with HMRC. You must register as an employer before your first employee's first payday. HMRC will give you an employer PAYE reference number. You then run payroll each month, deducting income tax and employee NI from gross pay and paying employer's NI on top. Most trade businesses outsource this to their accountant for £50–£100 per month.
• Employer's liability insurance. This is a legal requirement from day one of employment. It covers you if an employee is injured or becomes ill as a result of working for you. The law requires a minimum of £5 million cover; most policies provide £10 million. Budget £200–£600 per year.
• Written contract of employment. You must provide a written statement of employment particulars on or before the first day. This covers salary, hours, holiday entitlement (statutory minimum is 28 days including bank holidays for a full-time employee), notice period, and job description. Use a solicitor-drafted template from ACAS or a reputable HR service.
• Pension auto-enrolment. You must automatically enrol eligible employees into a workplace pension scheme. Employees aged 22 to state pension age, earning over £10,000 per year, must be enrolled. The minimum employer contribution is 3% of qualifying earnings. NEST is the government-backed scheme and is free to use.
• Right to work check. You must check that your employee has the legal right to work in the UK before they start. For UK and Irish citizens, a passport or birth certificate plus National Insurance number is sufficient. Keep copies of all documents.

Finding your first hire

The best first hires for most trade businesses come through existing networks rather than job boards. Start with these sources:

• Word of mouth from other tradespeople. Ask colleagues and contacts whether they know a reliable engineer looking for a change. Someone who comes recommended by a trusted peer is far lower risk than an unknown applicant.
• Trade forums and Facebook groups. UK trade communities on Facebook (there are active groups for most trades) regularly have engineers posting that they are looking for work. Post that you are hiring with a brief description of what the role involves.
• Local apprenticeship providers. Contact the college or training provider for your trade in your area. They often have recently qualified apprentices looking for employed positions, or can recommend candidates who are close to finishing their training.
• Checkatrade and trade directories. Engineers who have their own profiles but are looking for more stable employed work sometimes advertise this. It is worth reaching out to well-reviewed local tradespeople in your trade to ask if they are open to a conversation.
• Indeed and Reed. Job boards work, but expect a wide range of applicant quality. Write a specific job description that clearly states the trade requirements, your location, expected hours, and salary range to filter out unsuitable applicants.

Onboarding your new engineer

The first four weeks with a new hire set the tone for everything that follows. A structured onboarding process — even a simple one — makes the difference between a new employee who gets up to speed quickly and one who struggles and feels unsupported.

In week one, work alongside your new hire on every job. Do not send them out alone yet. Show them your standards, your customer communication style, and how you like jobs to be left. Explicitly point out the things that matter to you and why. This is also when you assess what they are capable of and what needs more development.

From week two, you can begin giving them jobs independently — starting with simpler, lower-risk work — while staying in close contact by phone. Check in after each job, ask what went well and what did not, and reinforce your standards consistently.

By week four, you should have a clear picture of their capabilities, their attitude, and whether the relationship is working. Address any issues early; do not let problems fester in the hope they will resolve themselves.

How Trade2Base helps you manage a growing team

The administrative overhead of managing even one additional engineer is significant if you are relying on phone calls, text messages, and paper job sheets. Trade2Base is built for trade businesses that are growing beyond a one-person operation.

With Trade2Base, you can assign jobs to specific engineers and see each person's diary independently. Engineers receive job details directly on their phone — customer address, job description, access notes, and any photos or documents you attach. When they complete a job, they mark it done in the app, triggering an automated customer follow-up and flagging the job for invoicing.

You can track each engineer's performance over time: jobs completed per week, average job value, customer satisfaction scores. This gives you real data for performance conversations rather than vague impressions. For a first-time employer navigating the transition from solo to team, having that visibility is genuinely useful.
