From Employed to Self-Employed Tradesperson: When Are You Ready?

You're ready to go self-employed as a tradesperson when you have regular work lined up from more than one source, several months of living costs saved, a day rate that covers your costs and tax, and the basics in place: HMRC registration, insurance, a business bank account and a way to quote and invoice. If one of those is missing, fix it before you hand in your notice.

Many tradespeople start out employed by a firm, then pick up private jobs in the evenings and at weekends. At some point the weekend work starts to look like a business. Here's how to tell whether it is.

The money question

When you leave employment you lose a regular wage, holiday pay, sick pay and any employer pension contributions. Your self-employed income has to replace all of that, and pay for your own van, tools, insurance and tax. Start with your personal monthly costs (mortgage or rent, bills, food, family), then add your business costs. That total is what your trade has to bring in every month, quiet or busy.

Signs you're ready

• You're turning down private work because you can't fit it around your employed hours
• Your private income is getting close to your wage
• Customers come back and recommend you to others
• Work comes from more than one source: homeowners, letting agents, contractors
• You've priced jobs properly and still won them
• You have savings to cover quiet weeks and bad weather

Signs you're not ready yet

• All your work comes from one contractor, which leaves you exposed if they go quiet
• You haven't saved a buffer
• You haven't worked out a day rate that covers your costs and tax
• You don't yet have the tools, van or certifications the work needs
• You're leaving to get away from a bad job rather than towards enough good work

Work out your day rate first

Your employed hourly wage is not your self-employed rate. You'll bill fewer days than you work, and every cost is now yours. Use our guide to pricing trade work and the free rate calculator to find a rate that covers costs, tax, holidays and quiet months.

The admin to sort before you start

• Register as self-employed with HMRC for Self Assessment (or set up a limited company if that suits you better; take advice)
• Register for CIS as a subcontractor if you'll work for contractors in construction, so deductions are 20% rather than 30%
• Get public liability insurance, plus cover for your tools and van
• Check any scheme membership or certification your trade needs to sign off its own work
• Open a separate business bank account
• Set aside money for tax from your very first job

Our Self Assessment guide for tradespeople covers deadlines, payments on account and what you can claim. As you grow, keep an eye on the £90,000 VAT registration threshold, and on Making Tax Digital for Income Tax, which applies to sole traders with qualifying income over £50,000 from April 2026, over £30,000 from April 2027 and over £20,000 from April 2028.

Set up quoting and invoicing from day one

The paperwork you send is how new customers judge whether you're a proper business. Have a branded quote and invoice ready before the first job, with your bank details and payment terms on them; our guide to writing a professional invoice covers what to include. You can start with the free invoice generator and estimate generator in your browser. Once you're sending invoices every week, the AllSquare iOS app keeps your customers, price list, quotes and invoices on your phone. The free plan includes 2 invoices and 2 estimates a month, and AllSquare Pro is unlimited. Starting digital also saves a messy switch later; see why trades are going paperless.

Know where the work will come from

Before you go, write down where the next three months of work is coming from: repeat customers, referrals, letting agents, and contractors you've worked alongside. A free business listing on the main search and map sites, a simple website and reviews from past customers help new customers find and trust you. Paid lead sites can fill gaps, but weigh the cost of each lead against your margin on the jobs it brings. Whatever the source, the habit that matters is the same: reply quickly and send a clear written quote, ideally the same day. Our quoting guide shows how.

The first 90 days

Expect lumpy income. Some weeks you'll be flat out, others quiet. Use the quiet ones to follow up quotes, ask happy customers for reviews and referrals, and get your paperwork straight. Invoice every job the day it finishes, chase anything overdue straight away, and keep track of which kinds of job actually make you money. Whether you're a plumber, an electrician or a mechanic, the first months are about building a reputation and a routine.

There's never a perfect moment

Nobody will tell you you're ready. If the work is there from more than one source, the numbers add up and the admin is in place, you've done what you can to reduce the risk. The rest is doing good work and getting paid for it.
