In construction, even small improvements in gross margin can completely transform your bottom line. A 5% increase may not sound like much, but in reality, it can mean hundreds of thousands of pounds in extra profit each year.
As an accountant and business advisor specialising in the construction industry, I’ve seen first-hand how focusing on just a few key areas can make a huge difference. Here are three proven strategies that consistently deliver results for construction business owners.
1. Track Job Profitability in Real Time
One of the biggest mistakes construction firms make is waiting until the year-end accounts to discover whether projects were profitable. By that point, it’s too late to fix the issues.
Instead, set up job-level reporting so you can monitor the margin on each project as it progresses. This allows you to:
-
Spot issues early, before they eat into profits
-
Take corrective action mid-project
-
Compare estimated vs. actual costs in real time
👉 Extra step: Track both project-level performance and overall business performance. If your overall accounts show 20% margins, but every job is reporting 15% or less, something isn’t adding up. Identifying these gaps will highlight hidden inefficiencies.
2. Define Your Target Gross Margin
Too many construction businesses try to “work it out as they go.” Without a clear target, you’re effectively guessing.
Ask yourself:
-
What should your mark-up be?
-
What margin do you need to run a sustainable, profitable business?
-
How does this compare with industry benchmarks?
By setting a clear target margin, you create a benchmark for success. You’ll know exactly what “good” looks like, and you can hold your team accountable for hitting it.
3. Drill Down Into the Details
Once you have accurate reporting and a clear margin target, the real work begins. If a project falls short, investigate:
-
Was it materials (rising prices, wastage, poor supplier terms)?
-
Was it labour (overruns, subcontractor inefficiencies)?
-
Or was it a combination of both?
Fix the problem, track results, and repeat the cycle. This ongoing process is what drives long-term profitability improvements in construction businesses.
The Power of a 5% Margin Improvement
Here’s a real-world example that shows just how powerful small improvements can be:
-
Annual turnover: £3 million
-
Current gross margin: 13% (£390,000 gross profit)
-
Target gross margin: 18% (£540,000 gross profit)
That’s an extra £150,000 profit every year — without increasing turnover.
Over 10 years, that’s your pension covered.
Over 5 years (often less), that’s a commercial property paid for, generating ongoing rental income.
Or, in some cases, it’s simply the difference between staying in business and going under.
Why This Matters for Construction Businesses
Construction is a tough industry with tight margins, unpredictable costs, and increasing competition. Improving your gross margin isn’t just about making more money — it’s about building resilience, creating cash to grow, and securing the future of your business.
By focusing on real-time reporting, clear targets, and detailed analysis, you’ll put yourself in control of your profitability instead of leaving it to chance.
Final Thought
Don’t underestimate the impact of making these changes. Just a 5% improvement could transform your construction business over the next 12 months.
