How to Increase Your Profit Margins as a Tradesperson
Most tradespeople think the way to make more money is to take on more work. More jobs, more hours, more income. But if your margins are thin, more work just means more of the same problem at a larger scale. You end up busier, more stressed, and still not significantly better off.
Improving your profit margins means making more money from the work you’re already doing – not just doing more of it. Here’s how.
Understand Your Current Margins First
You can’t improve what you’re not measuring. Before anything else, you need to know what your current margins actually are – not what you assume they are.
For each job, your gross margin is the difference between what you charged and what the job actually cost you in labour time and materials. A job quoted at £500 that cost you £350 in time and materials has a gross margin of 30%. A job quoted at £500 that actually took longer than expected and cost £430 all in has a margin of 14%.
Most tradespeople don’t track this per job. They just look at their bank balance at the end of the month and feel broadly okay or broadly worried. That’s not enough information to make good decisions.
A job management app like Tradify lets you log actual time and materials against every job so you can see your real margin rather than guessing. Over time patterns emerge: certain job types consistently make money, others consistently don’t, and you can adjust your pricing or your workload accordingly.

This is the highest-leverage thing you can do for your margins and it costs you nothing to implement. A 10% price increase on every job is a 10% improvement in gross margin, without working a single extra hour.
The fear is always that customers will leave. The reality is that most won’t, especially if you’ve been reliable, do quality work, and give proper notice for existing customers. Research shows 81% of UK tradespeople are planning price increases in 2026. The market is moving. Get ahead of it rather than behind it.
2. Mark Up Materials Properly
If you’re supplying materials on a job and not applying a markup, you’re doing free procurement work. Your time sourcing, ordering, collecting, and managing materials has a value – and so does the credit risk of buying materials before the customer has paid.
The standard materials markup for UK tradespeople is 10–20% on top of your trade price. Apply it consistently on every job. It won’t price you out of work; customers expect materials to be marked up and most never query it when it’s included in a clear, itemised quote.
3. Get Better at Estimating Job Costs
Underquoting is one of the biggest margin killers in the trades. You quote a job based on what you think it’ll take, it runs over, and suddenly the margin you expected is half what it should be – or gone entirely.
The fix is keeping records of similar past jobs and using them to inform future quotes. If bathroom refits consistently take 20% longer than you initially estimate, build that buffer into every bathroom quote going forward. Job management software earns its keep here: when every job is logged with actual time and costs, you build a reference library of real data that makes future quotes more accurate and more profitable.
4. Reduce Time Wasted on Admin and Travel
Every hour you spend on unpaid admin – writing quotes by hand, chasing invoices, managing paperwork, driving back to the merchant for something you forgot – is an hour you’re not billing for. That dead time directly reduces your effective day rate even if your headline rate looks fine.
- Use saved materials and labour lists – rather than building every quote from scratch, use a system that stores your standard rates and items so quotes take minutes not hours
- Invoice immediately – send the invoice the moment the job is done, not at the end of the week when you get round to it
- Batch your merchant runs – plan material orders in advance so you’re not making multiple trips per job
- Group jobs by area – scheduling jobs in the same geographic area on the same day cuts travel time and fuel costs significantly
5. Be More Selective About the Work You Take On
Not all work is equal. Some jobs are straightforward, well-paid, and done in a day. Others involve difficult access, awkward customers, lots of back-and-forth, and end up taking three times longer than planned. Both might be quoted at the same day rate, but one is far more profitable than the other.
When you’re busy enough to have a choice, prioritise:
- Jobs where your skills command a premium – specialist work, complex installs, emergency callouts
- Repeat customers you already have a relationship with – less time quoting, more time working
- Larger jobs with better overall margins – one well-priced week-long job often beats five days of small jobs after you factor in travel and admin
- Customers who pay promptly and without fuss
6. Reduce Your Overhead Costs
Improving margins isn’t only about increasing what comes in; it’s also about reducing what goes out. Go through your business expenses once a year and challenge every line:
- Are you on the best deal for van insurance? Comparison sites take 20 minutes and can save hundreds
- Are you using a fuel card to reduce fuel costs?
- Are there software subscriptions you’re paying for but not using?
- Are you claiming all the expenses you’re entitled to? Many tradespeople leave tax deductions unclaimed every year
7. Get Paid Faster
Cash in the bank and profit on paper are different things, but getting paid faster improves both. The longer money sits in unpaid invoices, the more pressure you’re under to take on more work just to cover your costs in the short term – that pressure leads to taking on lower-margin jobs you’d otherwise turn down.
Deposits upfront, online payment options, and prompt invoicing all speed up the cash cycle.
The Bottom Line
Better margins come from a combination of charging more, spending less, wasting less time, and being more selective about the work you take on. None of these require you to work more hours – in fact most of them mean working smarter with the hours you already have.
Pick one area from this list and focus on it for the next month. Track the difference. Then move to the next one. Small, consistent improvements compound quickly.

Seven levers make the biggest difference: raise your prices (even a 10% increase has an immediate impact), mark up materials consistently at 10–20% on top of your trade cost, improve your job estimating accuracy using records of past jobs, reduce time wasted on admin and travel, be selective about the jobs you take on, cut overhead costs, and get paid faster through deposits and prompt invoicing.
A healthy gross profit margin for a UK sole trader tradesperson is typically 35–50% on labour. Net profit (after overheads) should be a minimum of 15–25%. If your net margin is below 15%, you are not making enough to cover slow periods, tool replacement, or unexpected costs. Use job management software to track your actual margin per job rather than estimating from your bank balance.
Yes. A markup of 10–20% on top of your trade cost is standard for UK tradespeople and is expected by customers when included in a clear, itemised quote. It covers your time sourcing, ordering, collecting, transporting, and managing returns on materials. Never supply materials at cost – you are providing a procurement service that has real value.
Job management software like Tradify lets you log actual time and materials costs against every job and compare them to the quoted price. Over time this builds a clear picture of which job types, customers, and locations are most profitable. Without this data, you are guessing at your margins based on your bank balance rather than knowing them from your job records.
Give existing customers advance notice, most tradespeople raise prices with 30 days’ notice and explain it clearly as a reflection of increased material and living costs. Apply new pricing to all new customers immediately. Be confident: customers who value your work will accept reasonable increases. The ones who threaten to leave over a 10% increase are usually not your best customers anyway. For a full approach, see our guide on how to raise your prices as a tradesperson.
Review your business expenses once a year and challenge every line: van insurance (comparison sites can save hundreds), fuel (a fuel card cuts cost and records it automatically), tool insurance, software subscriptions you are not using, and tax-deductible expenses you might be missing. Many sole trader tradespeople underclaim on allowable expenses and overpay tax as a result. An accountant familiar with the trades will often save more than their fee in unclaimed deductions alone.
