Going self-employed as a tradesperson is one of the best career moves you can make. But the first year or two is littered with avoidable mistakes that cost real money and real stress.
These aren't obscure gotchas. They're the same mistakes almost every new tradesperson makes — including the successful ones who eventually figured it out.
Undercharging
Nearly every tradesperson who goes self-employed starts by charging too little. You're nervous about losing work, you don't want to seem expensive, and you figure low prices will help you build a customer base quickly.
The problem: once you're known as the cheap option, it's incredibly hard to raise your prices. Customers who found you because you were the cheapest will leave the moment you're not. Research what others in your area charge and aim for the middle, not the bottom.
No Written Quotes
Verbal quotes are an invitation for disaster. "I thought you said £400, not £600." Every one of these arguments is prevented by putting the quote in writing.
A clear text message with the scope, price, what's included, and what's not is legally sufficient and takes five minutes. Get confirmation in writing too — "Sounds good, go ahead" in a text message is a record of acceptance.
Not Taking Deposits
New tradespeople are often too nervous to ask for deposits. In reality, established tradespeople always take deposits on larger jobs. It's standard practice and customers expect it.
A deposit confirms the customer is serious, secures your diary, and gives you cash flow to buy materials. For jobs over £300-500, a 25-30% deposit is perfectly reasonable. If a customer refuses, treat it as a warning sign.
Poor Record Keeping
Shoeboxes of receipts. Text messages with vague job descriptions. No invoices for cash payments. Poor record keeping costs you money in two ways: you can't claim expenses you can't prove, and if HMRC investigates, poor records lead to estimated assessments and penalties.
Tools like Gaffer track your jobs and invoices automatically. But even a simple spreadsheet updated daily is infinitely better than trying to reconstruct your year from bank statements in January.
Trying to Do Everything
When you're new and hungry, it's tempting to say yes to everything. Plumbing, tiling, carpentry, painting. Doing work beyond your competence risks property damage and the kind of review that follows you around for years.
Stick to what you're qualified for. Build relationships with other tradespeople who can handle the rest. Referring work to others is professional, not a weakness.
Ignoring Marketing
Many new tradespeople assume work will just come through word of mouth from day one. It won't — not in the beginning. Word of mouth takes time to build.
The minimum: set up a Google Business Profile (free, twenty minutes), create a Facebook business page (free, ten minutes), and ask every happy customer to leave you a Google review. These three things alone will get you appearing in local searches.
Not Having Insurance
Public liability insurance costs £100-200 a year. Skipping it to save money is like skipping brake pads to save on car maintenance. One accidental flood, one damaged floor — and you're personally liable for thousands.
Many customers and all commercial clients will ask for proof of insurance before letting you through the door. Get it on day one.
Every successful tradesperson made most of these mistakes at some point. The trick isn't avoiding all mistakes — it's recognising them quickly and fixing them before they become habits.
