The numbers don’t care how good your latest building project looks…
Tuesday, February 24th, 2026
OK. Take a deep breath. You’re in for a ride. I’m not holding back.
“My lads cost me £200 a day.”
Is this what you’re telling yourself?
Because they don’t.
You pay them £200.
They cost you closer to £230–£260 once you add:
- Employer’s NI
- Pension
- Holiday pay
- Sick days
- Travel time
- Downtime between jobs
- Insurance
- Training
- The van they sit in.
That’s the real number. Those are your overheads. But there’s more.
You don’t price for the average day
Here’s where building costs get brutal.
Most builders price for the smooth version of the job.
The on-time deliveries.
The dry weather.
The client who doesn’t change their mind.
But you don’t build in ideal conditions.
You build in:
- Rain
- Delayed materials
- Subbies not turning up
- Inspectors running late
- Clients adding “just one small thing”.
And that pushes your minimum viable margin far higher than most builders expect.
Fixed costs don’t flex
A potential customer can bail at the last minute.
A builder can’t send the van finance back.
You carry:
- Public liability insurance
- Employer’s liability
- Tool insurance
- Van finance or leases
- Yard or storage
- Accountants
- Software
- Phones
- Fuel
- Compliance.
These don’t disappear when work slows down.
They sit there.
Quietly.
Waiting to be paid.
Busy isn’t safe
Here’s possibly the most dangerous misconception in construction:
“If we’re busy, we’re fine.”
Wrong.
Busy builders often make less money.
Because:
- You underpriced to win it
- You’re firefighting instead of managing
- You’re fixing mistakes at your own cost
- You’re absorbing variations without charging.
Turnover hides weak margins.
One bad job doesn’t average out
In construction, losses compound.
One underpriced extension can wipe out:
- Three decent extensions
- A year’s earnings
- Your personal drawings.
You don’t “make it back next month.”
You carry it.
Through cash flow.
Through stress.
Through sleepless nights.
Scope creep is invisible
I’ve written and spoken about this a lot. No one sees it happen.
“While you’re here…”
“Can you just…”
“It won’t take long…”
Individually, they feel harmless.
Collectively, they destroy margin.
And because builders want to be decent, professional, helpful – they absorb it.
You don’t lose money in dramatic moments.
You lose it in polite ones.
Compliance isn’t optional
Health & safety.
Contracts.
Building control.
Waste transfer notes.
CDM.
Regulation changes.
None of it generates revenue.
All of it carries risk if ignored.
Construction isn’t just building.
It’s regulated risk management in muddy boots.
The scarier bit – when work slows down
…the pressure doesn’t ease.
It intensifies.
Because:
- You still have wages to pay
- The fixed costs don’t change
- The pipeline looks thin
- You’re tempted to drop your margin just to keep the diary full.
That’s when most builders quietly damage their own business.
They trade profit for security.
But low margin isn’t security.
It’s a slow bleed. I told you it was brutal!
Why builders really struggle
Building companies don’t usually fail because no one wanted their work.
They fail because:
- Labour crept
- Variations weren’t charged
- Overheads weren’t fully understood
- Profit was treated as optional
- One bad month wiped the buffer.
Construction isn’t just craftsmanship.
It’s financial control with lots of uncertainty.
And the numbers don’t care how good the finish looks on handover day (although if you want a decent review of course it should absolutely look good…).
There is light at the end of the tunnel!
The last thing I want you to do having read this article, is throw in the towel. I know I’ve gone in hard!
I’m actually here to say – we hear you – we understand what you go through.
And the good news is that it IS possible to make a decent profit and earn a proper living.
Not like an employee but as the owner of a viable, sustainable business.
Through software tools that provide accurate estimating, straightforward job and task management, support with health and safety, and plain english customer and sub-contractor contracts.
And better still, they’re not complicated or time-consuming.
They’re mostly automated.
You provide the job spec and the software tools pretty much take it from there.
The biggest hurdle is early on while you get your head round the software.
But a bit of head scratching is a small price to pay for time saved, profit made, stress relieved? No?
And of course we’re here to help – then and always.
And if you want even more support, we can also teach you, mentor you, advise on changes to your business…
