Case study: a £3.5M contractor raised prices 12%. Lost zero work.

Most owners assume raising prices means losing work. The maths often disagrees.

We worked with a £3.5M Midlands contractor last year. Refurb and small commercial fit-out. Reliable client base, mostly repeat work and referrals.

Their problem wasn't volume. They had plenty. Their problem was that volume wasn't translating into cash.

Net margin: 5.8%. Cash reserves: thin. Director drawings: modest for a £3.5M business.

When we ran the analysis, three things were clear:
• Quotes hadn't been reviewed in 3 years (inflation alone meant they were 15% behind)
• Variations were being absorbed, not invoiced
• Two clients consistently took 50% longer to pay than the rest

The brief was simple: test the market on price.

What we did:
✅ Raised standard rates by 12% across the board
✅ Started invoicing variations properly with clear scope notes
✅ Put a 28-day payment term on new contracts (down from 45)
✅ Held the line in negotiation (this was the hardest part)

Result over 9 months:
• Net margin moved from 5.8% to 11.4%
• Lost work: zero. Repeat clients didn't blink.
• Two new clients pushed back, were given the option to negotiate on terms not price. One walked. One stayed.
• Cash position improved by £210K
• Director took a proper salary for the first time in 4 years

The owner's reflection: 'I'd been telling myself for years that the market wouldn't take a price rise. The market didn't even notice.'

Most contractors are underpriced by 8 to 15% and have been for years. The only way to know is to test it.

4 quoting mistakes that quietly destroy margin.

Most quoting problems aren't dramatic. They're small habits that compound across hundreds of jobs.

Four of the most common in UK construction firms £750K to £15M:

1. No risk premium on difficult clients.
Some clients are 30% harder to work for than others. Slow approvals, scope creep, dispute happy. Yet most contractors price them the same as the easy ones. The clean clients subsidise the difficult ones.

2. Variations priced at cost (or worse, not priced at all).
Variations are where margin lives. They're discretionary, urgent, and the client has already committed. Yet most contractors price them off the same rate card as the main work, or do them 'as a favour'. That's 5 to 8% of total annual margin gone, every year.

3. No floor price for the type of work.
Every contractor should know their walk-away number for each category of work. Below this, the answer is no. Without one, you take work at break-even when you're hungry and resent it later.

4. Pricing the job, not pricing the year.
A £200K job at 8% net is £16K. Same time and management spent on a £200K job at 14% is £28K. Over 50 jobs a year, that's a £600K profit difference for the same effort. Most owners price each job in isolation, never zooming out.

The fix for all four is the same: a pricing framework that's used consistently, reviewed quarterly, and not negotiated away under pressure.

What's your average win rate on quotes?

Honest question for the construction owners reading 👇

Of every 10 quotes you submit, how many do you typically win?

🅰️ 1 to 2. We chase volume, hope something sticks.
🅱️ 3 to 4. Average. Some weeks better than others.
🅲️ 5 to 7. Decent strike rate. We pick our battles.
🅳️ 8+. We almost never lose work we go for.

There's no objectively right answer, but each one says something specific.

A means you're quoting too much, too cheap, or to the wrong clients.

D might mean you're underpricing. If you're winning everything, you're probably leaving money on the table.

The sweet spot for most £750K to £15M contractors is C: high enough to keep the pipeline healthy, low enough that you're testing your price.

Which one are you? A, B, C or D in the comments.

Most contractors quote on cost. The ones making real money don't.

Watch how most construction firms price a job.

Materials. Labour. Plant. Sub-contractor costs. Overhead allocation. Add a margin. Send the quote.

It's the natural way. It's also the reason most contractors are stuck on single-digit net margins.

Here's what they're missing:

Cost-plus pricing answers the wrong question. It asks 'what does this job cost us?' when the better question is 'what's this job worth to the client?'.

Value-based pricing flips the lens. The same fit-out for an empty unit and the same fit-out for a tenant losing £4K a day are two completely different jobs commercially. The cost is similar. The value isn't.

Owners who get this right ask different questions before quoting:
✅ What's at stake for the client if this job goes wrong?
✅ What's the cost of delay to their operation?
✅ Are we one of three quotes, or the only one they trust to deliver?
✅ Is this a relationship-build job, or a one-time piece of work?

Cost still matters as a floor. You won't price below it.

But the ceiling is set by value, not by what your competitors are charging.

Most contractors leave 8 to 15% margin on the table on every job. Year on year, that's the difference between being on the overdraft and building real equity.

5 questions every construction owner should ask themselves once a year.

After many weeks of writing about construction finance, this is the post we want owners to come back to.

Five questions. Once a year. Two hours with a notebook and a coffee.

1. If I went on holiday for 4 weeks tomorrow, what would happen to the business?
Honest answer. Not what you'd like to be true.

2. What's my real net margin, after everything is loaded in properly?
Not the gross. Not the management accounts. The number that's actually left.

3. If my biggest client left tomorrow, how long until the business felt it?
Days, weeks, months? The answer tells you everything about concentration risk.

4. What would the business sell for today, honestly assessed?
Not what you'd like. What a buyer would actually pay.

5. What's the gap between this business and the one I'd actually want to be running?
Both directions. Bigger and smaller are both valid answers.

If you can answer all five with confidence, you're ahead of 90% of construction owners.

If you can't answer one or two, that's where the work is.

Most owners spend more time choosing a holiday than they do answering these. And then wonder why the business never quite feels under control.

Two hours. Once a year. The highest-leverage thinking you'll do all year.

Case study: the £8M owner who scaled back to £5M. And his life changed.

We work with construction owners who want to grow. Most do.

But this story is about one who went the other way. And it might be the most important case study we've ever shared.

He'd built the firm from £400K to £8M over 14 years. Strong order book. Decent margins. Solid reputation.

He was also: 56. Divorced. Estranged from his teenage daughter. 22kg overweight. On blood pressure medication. Working 65-hour weeks.

His comment to us in the first meeting: 'I built this thing and I don't know if it built me, or it ate me.'

We didn't suggest scaling back. He did. We modelled what it would look like.

The maths:
• Drop turnover from £8M to £5M
• Increase net margin from 7% to 12% by being selective on work
• Same take-home for the director
• £1.4M lifestyle cash position within 3 years
• Hours dropped from 65 a week to 38

It took 18 months. By the end:
• He'd rebuilt the relationship with his daughter
• Lost 15kg, came off the BP medication
• Was earning the same money for 60% of the hours
• The business had higher margins, fewer headaches, more cash

His reflection two years later: 'I thought scaling back meant losing. Turns out it meant winning.'

Growth isn't always the right answer. Sometimes the most commercial decision an owner can make is to want a different shape of business. The financial model just has to support whichever shape that is.

If you've been carrying the business in your head and wondering whether the price is worth paying, get in touch. There's almost always a better-shaped version of what you're already running.

Most construction owners have never decided what 'enough' actually looks like.

Here's a question we ask every owner in their first proper review with us.

What does enough look like?

Most can't answer. Not because they haven't thought about it, but because they've thought about it in the abstract instead of in numbers.

'Enough' has three parts:

1. Income enough. The annual figure that means you don't feel financial pressure month to month. For most £750K to £15M construction owners, this number is between £80K and £180K take-home.

2. Asset enough. The total wealth (business + property + pension + savings) that means you'd be okay if the business stopped tomorrow. Usually £1M to £3M for owners in their 40s and 50s.

3. Life enough. The mix of work, family time, holidays, hobbies, fitness that makes the rest worth doing.

Most owners are over-optimising on number 1 (income) while under-investing in numbers 2 (assets) and 3 (life).

The reason matters: if you don't know what enough looks like, you can't tell when you've got there. So you don't stop. You keep going. And the business keeps demanding more, because no one's drawn the line.

The exercise is simple. Sit down with your spouse. Write down a number for each of the three. Compare them to what you've got now. Then ask: what's the actual gap, and how long does closing it really take?

Most owners find the gap is smaller than they think. Which raises the question of why they're still pushing as hard as they are.

When did you last take a proper holiday?

Honest question for the construction owners reading 👇

When did you last take a proper holiday? No emails, no calls, no Friday morning quote you 'just had to send'?

🅰️ Within the last 6 months
🅱️ This year, but I checked my phone every day
🅲️ Over a year ago
🅳️ Can't actually remember

No judgment. But the answer says something about the structure of the business, not the discipline of the owner.

If you can't switch off for two weeks, you don't have a business that can run without you. You have a job that pays you whatever's left.

That's worth knowing.

A, B, C or D in the comments.

You're paying for the business in your head. You just don't see the invoice.

Most construction owners think the cost of running their business is what shows up in the management accounts.

It isn't.

There's a second invoice nobody sees. It gets paid every day:

• The decision you can't switch off at 9pm
• The Sunday night dread before Monday
• The mental open tab on every job, every supplier, every PM you're worried about
• The quiet calculation when your phone rings on a Saturday
• The conversation with your partner that ends in 'work, again'

This isn't soft stuff. It's a real cost. It shows up as:
• Decisions made on tiredness instead of clarity
• Opportunities missed because you couldn't see them through the fog
• Health issues that compound until they're expensive
• Relationships that strain quietly until they don't

Most construction owners we work with don't realise how much they're carrying until something forces them to put it down.

The structural fixes are the same things we talk about all the time:
✅ Forecasts that mean you sleep at the weekend
✅ Management accounts that tell you the truth without you having to dig for it
✅ Delegation that's actually trusted, not just delegated
✅ A senior layer that can hold the weight when you step away

The point isn't to work less. It's to carry less while building more.

The hire vs subbie decision is a financial decision, not a labour one.

Most construction owners decide between hiring and using subbies based on availability and gut feel.

It's a financial decision dressed up as a labour one.

The real maths on a typical £45K site role:

Employee:
• Salary £45K
• Plus 12% NI + pension = £50.4K
• Plus van, fuel, kit, training = £56K all-in
• Fixed cost. Paid whether the work's there or not.
• Builds team strength and operational predictability.

Subcontractor:
• Day rate £280, 220 working days = £61.6K
• Variable cost. Paid only when needed.
• No team development. No loyalty premium. CIS admin.
• Risk: availability vanishes when the market tightens.

The decision flips depending on:
✅ How predictable your pipeline is
✅ Whether you're trying to build long-term value or stay nimble
✅ Your cash position (employees need 12 months of forward cash, subbies don't)
✅ Whether the role is core or peripheral to delivery

Most growing firms over-subbie when they should be hiring, then over-hire when they should be flexing.

The clean answer: hire the core team that defines your delivery. Subbie everything else.
