Profit Margins for UK Trade Businesses — What's a Good Margin and How to Improve Yours in 2026

Gross Profit vs Net Profit — Why Both Matter

These two numbers tell very different stories about your business. Confusing them is one of the most common reasons tradespeople underprice their work.

A decorator turning over £80,000 with a 60% gross margin has £48,000 in gross profit. If overheads run to £18,000 a year, net profit is £30,000 — a 37.5% net margin. That's healthy. But if materials have been undercharged, the gross margin shrinks to 45% and net profit collapses to £18,000. Same turnover, very different outcome.

Typical Profit Margins by Trade (UK, 2026)

These are realistic ranges for sole traders and small teams. Where you land within the range depends on your pricing, how efficiently you run jobs, and how tightly you control overheads.

Ranges reflect sole traders and owner-operated businesses. VAT-registered businesses should calculate margins on net (ex-VAT) figures only.

Materials Markup: The Hidden Margin Leak

Industry standard for materials markup is 15–25% on cost. Yet a large proportion of UK tradespeople either pass materials through at cost or apply a token 10% — effectively subsidising their customers' kitchens, bathrooms, and boilers.

There are legitimate reasons you should charge a markup: you're sourcing, transporting, storing, and taking on the risk of defective or incorrect goods. Your time driving to the merchant, loading, and unloading is not free. A 20% markup on £3,000 of materials is £600 — that's a meaningful contribution to your net margin that many tradespeople are simply leaving on the table.

If a customer pushes back on your materials charge, explain that your price includes sourcing, delivery risk, and any returns — which is true and entirely reasonable. Most will accept it. If they don't, that's useful information about whether they're a good fit for your business.

Labour Recovery Rate: The Number Most Tradespeople Ignore

Your hourly or day rate is only meaningful if you know how much of your time you can actually bill. Your labour recovery rate is the percentage of working hours that generate invoiced revenue.

Think about a typical week. If you work 50 hours but spend 5 hours driving to quotes, 4 hours on admin and invoicing, 2 hours on merchant runs not billed to a specific job, and 4 hours on unbillable travel — you're billing roughly 35 hours. Your recovery rate is 70%.

The solution isn't to work more hours — it's to reduce non-billable time through better job planning, route efficiency, and systemising admin. Every hour you recover is pure margin improvement.

Calculating Your Real Overhead Burden

Your overheads are the fixed monthly costs that run whether you're on site or not. Many tradespeople underestimate these significantly — especially when running through a limited company where costs are spread across multiple accounts.

That's £10,800 a year that must come from your net margin before you see a penny of take-home. Add public liability insurance, professional memberships (Gas Safe, NICEIC, Checkatrade), fuel, and CIS deductions if applicable — many sole traders find their true overhead burden is closer to £15,000–£20,000 per year.

Write yours down. Total it up honestly. Then check whether your current turnover and gross margin are actually covering it — and leaving you with a liveable income on the other side.

The Job Profitability Trap

Here's a scenario that plays out regularly on UK building sites and in bathrooms across the country: you quote a kitchen fit at £5,000 with a comfortable margin. Then the job runs two days over. Maybe the units arrive damaged and need to be reordered. Maybe the customer keeps changing their mind, or there's hidden work behind the walls. Two lost days at £300/day is £600 gone — and that's before any additional materials.

A job with a theoretical 25% net margin can be wiped to break-even or worse by a single overrun. This is why job profitability tracking matters as much as upfront pricing.

The fix has two parts: better upfront scoping (build contingency into your quote for jobs with hidden unknowns), and variation orders for anything that falls outside the original scope.

Variation Orders & Daywork Rates: Charge for Scope Creep

Scope creep is one of the biggest silent killers of trade business profitability. The customer asks for “just a small extra thing” — an additional socket, a change to the tile layout, a second coat on a ceiling that wasn't in scope — and most tradespeople absorb it rather than cause friction. Over the course of a year, those freebies can cost thousands.

The professional solution is a written variation order (VO) process and a clearly stated daywork rate in your contract terms. A daywork rate is your time-and-materials rate for additional work — typically your day rate plus materials at markup. Having it written into your terms means you can refer the customer to it rather than negotiating from scratch each time.

Customers who respect your business will accept this. It also positions you as a professional rather than a tradesperson who can be talked into freebies.

How to Calculate Your Required Day Rate

Most tradespeople set their day rate by looking at what competitors charge. That's a reasonable starting point — but it tells you nothing about whether that rate actually covers your costs and leaves you a liveable income.

Here's the right way to work backwards from what you need:

Run this calculation yourself with your real numbers. Include honest overhead figures and realistic billable days (accounting for sickness, weather delays, and slow winter periods). The result is often a wake-up call — and a clear argument for a rate increase.

Six Ways to Improve Your Margin in 2026

When to Raise Your Prices

The right moment to raise your prices is after a busy spell — when you have more work coming in than you can comfortably handle and your lead time is stretching out. At that point, demand exceeds your capacity, which is the definition of a market that will absorb a price increase.

A 10% price increase with a 5% drop in enquiry volume leaves you better off financially with less work. Most tradespeople who push through a modest annual price increase find it has little to no effect on conversion — because customers largely shop on trust and availability, not on being the cheapest.

What you should never do is raise prices mid-job or quote one rate and invoice another. That destroys trust and generates the kind of review you don't want on Google. Price increases apply to new quotes only.

Marketing That Makes You Profitable — Not Just Busy

There's an important distinction between marketing that fills your diary and marketing that improves your profitability. Being fully booked at the wrong rate with the wrong jobs is not success — it's a treadmill.

To understand which marketing channels are genuinely profitable, you need to track more than just leads. You need to know: what did the lead cost, did it convert to a booked job, what was the job value, and what was the margin on that job. When you have that data by channel — Google Ads, Checkatrade, word of mouth, Google Business Profile — you can make rational decisions about where to spend next month's marketing budget.

Most UK tradespeople are running marketing spend on instinct. They continue with Checkatrade because “it brings work in” without knowing whether that work is more or less profitable than jobs sourced through other channels. Tracking cost per lead — and cost per booked job — by channel is the foundation of a marketing strategy that actually improves your bottom line.
