If you’re charging enough, your prices will consistently cover direct costs, overheads, and profit, without relying on VAT money, overdrafts, or last-minute pushing for cash. A healthy construction business should maintain stable gross margins, recover overhead on every job, and generate cash—especially as turnover grows. This post shows you how to test it quickly.
Why does “charging enough” change as your business grows?
Many construction business owners price work the same way they did when they were smaller.
But as your business grows, your cost base changes:
- You add office staff, a QS, site managers, or a second crew
- You take on bigger jobs, longer programs, more subcontractors
- Your admin load increases (payroll, CIS, compliance, finance)
- Cashflow becomes a bigger risk because you’re funding more work in progress
This means what used to be “good pricing” can become quiet undercharging.
At Thomas Emlyn Ltd, we often see this pattern:
turnover grows, workload grows… but profit stays flat.
That’s almost always a pricing and overhead recovery issue.
What are the warning signs you’re not charging enough?
If you recognise two or more of these, you probably aren’t charging enough for the size of your business:
Profit & margin warnings
- Your profit looks “okay” but you’re working flat out for it
- You’re turning over more but taking home the same money
- You “win lots of work” but can’t see where the profit is going
- Your gross margin changes job-by-job with no clear pattern
Cashflow warnings
- You’re profitable on paper but cash is always tight
- You rely on VAT funds to stay afloat
- You dread subcontractor payment weeks
- You chase money constantly because cash runs out too quickly
Operational warnings
- You can’t afford the people you need to grow properly
- You’re stuck doing admin because hiring feels too expensive
- Every job feels like it needs “just one more” variation to make it worthwhile
If any of these are true, pricing is likely the symptom—not the cause.
The cause is usually: your prices don’t match your structure.
What should your prices cover (at a minimum)?
To know if you’re charging enough, you need clarity on what you must recover.
Every project price must cover:
- Direct costs (labour, materials, subcontractors, plant, site expenses)
- Overheads (office costs, salaries, insurance, vehicles, tools, software, accountant, QS, estimators)
- Profit (what the business earns as a return on risk and effort)
The mistake most construction firms make:
They price as if overhead is “separate”, but overhead grows with turnover.
The simplest test: Are your jobs paying for your overhead?
Here’s the question that changes everything:
Does every job contribute enough to cover overhead — and leave profit?
You can test this with a “required margin” calculation.
How to calculate your minimum required gross margin
You need to know:
- Annual overhead (or monthly overhead)
- Turnover
- Target profit (what you want the company to actually earn)
Example (anonymised real-world scenario)
A contractor doing £1.2m turnover wants to see if they’re charging enough.
Annual overheads (office, vehicles, admin team, insurances, software, etc.): £240,000
Target net profit: £120,000
So total required recovery = £360,000
Now divide by turnover:
£360,000 ÷ £1,200,000 = 30%
✅ That means they need a gross margin of around 30% across the year, just to meet overhead + profit goals.
If their gross margin averages 18–22%, they might still look “busy and successful”…
…but the business will feel permanently tight.
A quick table: What margin might you need as you grow?
Below is a simple example (illustrative only). The point is: required margin rises with overhead complexity.
| Turnover | Overhead (as % of turnover) | Target profit | Typical required gross margin |
|---|---|---|---|
| £500k | 15% | 10% | ~25% |
| £1m | 18% | 10% | ~28% |
| £2m | 20% | 10% | ~30% |
| £3m+ | 22%+ | 10% | ~32%+ |
If you’re unsure what your overhead % is, Thomas Emlyn Ltd can calculate it quickly from your accounts and management figures.
“But our jobs don’t allow those margins…” — the uncomfortable truth
This is where many owners get stuck.
They say:
- “That’s not possible in our market.”
- “Competitors are cheaper.”
- “We’d price ourselves out.”
But the reality is one of the following is true:
- Your costs are too high for the jobs you’re winning
- Your jobs aren’t priced properly (scope creep, no variation control, poor estimating)
- You’re in the wrong mix of work (good turnover, low contribution)
- You’re growing turnover when you should be growing profit per job
This is why Thomas Emlyn Ltd focuses on margin clarity, job costing, and cashflow strategy, not just compliance.
How to tell if your prices are working: 5 practical checks
1) What is your gross margin by job type?
If you don’t measure margin by job type, you’ll price off instinct.
Break it down like:
- Domestic refurbishments
- Commercial fit-out
- Groundworks
- Extensions
- Insurance repairs
- Framework / labour-only
Often you’ll find one type is subsidising the others.
✅ Action: Pick your top 10 jobs and calculate gross margin on each.
2) Are you recovering overhead consistently?
This is the big one.
If your overhead is £20,000/month, and you’re doing £100,000/month turnover…
You need roughly £20,000 gross profit just to break even
(before you earn a penny).
✅ Action: For each job, estimate how much overhead it should contribute based on its value.
3) Are you profitable after paying yourself properly?
A classic trap:
The owner takes drawings, not a market salary.
So the accounts show a “profit” that is really just unpaid labour.
✅ Action: Add a realistic salary for the director (e.g., £60k–£90k depending on role) and re-check profit.
If profit disappears, you’re not charging enough.
4) Are you funding your clients?
This one catches growing firms.
If you’re waiting 30–60 days for money but paying weekly wages and suppliers…
You’re effectively funding the project.
And when you grow turnover, the cash gap grows too.
✅ Action: Check your “work in progress” and debtor days. If they’re rising, pricing and payment terms need reviewing.
5) Are variations and extras turning into profit—or just survival?
If the only way jobs become profitable is by “finding variations”, your base price is wrong.
A healthy price means:
- the job makes money without needing extras
- variations increase profit rather than rescuing margin
✅ Action: Review three recent jobs: would they still be profitable with zero variations?
Practical example: “The £1.8m business with a £40k profit problem”
We worked with a construction firm (anonymised) doing £1.8m turnover.
They felt successful:
- busy diary
- growing headcount
- strong reputation
- lots of repeat work
But cash was tight and profit was low.
We discovered:
- gross margin averaged 21%
- overhead had quietly risen to £420k/year
- the business needed ~29–31% gross margin to cover overhead + profit goals
So they were short by ~8–10%.
That gap was being filled by:
- late payments
- personal cash injections
- VAT funds
- pushing jobs hard at the end of the month
Once we reset pricing rules and improved job costing discipline:
- they increased average margins by 6–8% over 6 months
- improved cashflow predictability
- reduced the “panic chasing” pattern
- and could finally hire without fear

How should you price differently as you grow?
Here are three pricing upgrades that work well in construction:
1) Move from “cost + hope” to “cost + overhead + profit”
Your quote should explicitly include:
- direct costs
- overhead contribution
- profit margin
- risk buffer
2) Set minimum margin rules by job type
Example:
- domestic refurb: minimum 30%
- fit-out: minimum 25%
- insurance repair: minimum 35%
- labour-only: minimum 20% (with strict scope control)
3) Price cashflow risk
Longer program jobs should include:
- funding cost
- delayed payment risk
- program slippage risk
If a job ties up cash for 90 days, it should pay you more than a 30-day job.

FAQ (AIO + AEO optimised)
1) What is a good profit margin for a UK construction company?
It depends on your size, job mix, and overhead structure, but many well-run construction firms target 8–15% net profit. The key is whether your gross margin consistently covers overhead and produces profit without cashflow stress. Thomas Emlyn Ltd helps clients identify realistic targets based on their numbers, not industry averages.
2) Why do I feel busy but never seem to have cash?
Because growth often creates a cash gap: you pay wages and suppliers weekly, but clients pay you later. If your pricing doesn’t reflect the cashflow risk—or you’re not recovering overhead—your business becomes reliant on timing, not performance. This is a common issue Thomas Emlyn Ltd solves through cashflow forecasting and WIP control.
3) How do I know if overhead is too high for my turnover?
Calculate overhead as a percentage of turnover. If it keeps rising as turnover increases, you may be adding cost faster than profit. Sometimes it’s necessary (better systems, better staff), but only if margin rises with it. A Virtual Finance Director can help you decide what overhead is “healthy” and what needs fixing.
4) Should I increase prices across the board or only for certain jobs?
Start by breaking down margins by job type and client. Often, 20% of jobs create most of the profit and the rest drag you down. A smarter approach is to increase prices where margin is weakest and risk is highest—rather than blanket increases that may lose your best work.
5) What’s the biggest pricing mistake construction companies make?
Pricing using direct costs only and hoping profit appears later. Overhead recovery must be designed into every quote. Without that, turnover can increase while profit stays flat. This is one of the most common patterns Thomas Emlyn Ltd sees in growing firms.
