Week 2 - Why Some Contractors Keep Variations Verbal
And why paperwork suddenly matters at final account.
🗣 “Just Crack On - We’ll Sort the Paperwork Later”
Every subcontractor has heard this.
Usually said quickly.
Usually under pressure.
Usually while everyone’s trying to keep the programme moving.
The site manager points at an area and says:
“Can you just move that?”
“We need an extra run through here.”
“The client’s changed their mind.”
“We’ll get the instruction sorted later.”
And because the job is live:
labour is already there
access is available
everyone’s under pressure
nobody wants delay
…the work gets done.
That’s where the danger starts.
Because on many projects:
the less paperwork attached to a variation,
the easier it becomes to argue about later.
⚠️ The Truth Most People Already Know
Very few construction jobs finish exactly as tendered.
Things change constantly:
layouts
sequencing
specifications
access
client preferences
coordination
temporary works
programme priorities
Variations are normal.
The problem isn’t change.
The problem is:
how the change is managed.
And on some jobs, verbal instructions aren’t accidental.
They become part of the commercial culture.
🧱 Real Example: “It Was Only a Small Change”
A subcontractor working on a school refurbishment was asked repeatedly to make small adjustments:
additional containment
relocated services
out-of-hours working
revised access routes
Nothing huge individually.
And every time:
“We’ll get the paperwork sorted.”
The subcontractor trusted the relationship.
Didn’t want to slow the job down.
Didn’t want to become “difficult.”
So they kept going.
By final account:
over 40 separate verbal changes had never been formally instructed
labour impacts weren’t recorded properly
some work had become impossible to separate from original scope
The contractor’s commercial response became:
“Where’s the evidence these were variations?”
The subcontractor had carried out tens of thousands of pounds of extra work.
But commercially?
Much of it became:
argument instead of entitlement.
🔍 Why Verbal Variations Happen So Often
There are genuine operational reasons.
Site teams:
need speed
need flexibility
need problems solved immediately
Construction often moves faster than paperwork.
That part is true.
But there’s another side people rarely say out loud.
Verbal instructions also:
keep things flexible
delay cost discussions
avoid immediate commercial exposure
reduce visible project overspend
create ambiguity later
And ambiguity nearly always favours the party holding the money.
🧠 The Commercial Psychology Behind It
Here’s the uncomfortable truth.
A written variation:
creates evidence
creates valuation
creates liability
creates cost visibility
A verbal variation creates:
deniability.
Not always maliciously.
Sometimes people simply:
avoid difficult commercial conversations
hope costs can be absorbed later
think “we’ll sort it out somehow”
But by the time final account arrives:
budgets tighten
management reviews start
project losses appear
commercial scrutiny increases
Suddenly the same people who said:
“Don’t worry about paperwork”
start asking:
“Where’s the instruction?”
⚖️ The Site Team vs Commercial Team Divide
This is one of the biggest disconnects in construction.
Operationally:
“The work needed doing.”
Commercially:
“It wasn’t instructed properly.”
The site team often genuinely believes:
the subcontractor will be looked after
the variation is obvious
the cost will be sorted later
But months later:
the QS reviews the account
another PM takes over
senior management gets involved
And now the discussion changes completely.
Because commercially:
evidence matters more than memory.
🚨 The Biggest Mistake Subcontractors Make
Most subcontractors think:
“Everyone knows it changed.”
That is not the same as:
proving entitlement.
Construction disputes rarely revolve around:
whether work happened
They revolve around:
who instructed it
when it was instructed
whether it was part of original scope
whether notice was given
whether cost was agreed
That’s why paperwork suddenly becomes incredibly important at final account.
Not because anyone forgot the work happened.
Because:
undocumented work is easier to commercially resist.
🛠 What Strong Subcontractors Do Differently
The strongest subcontractors in the industry are often still:
cooperative
responsive
solution-focused
But they build commercial protection into the process.
They understand:
You can help the job and protect yourself at the same time.
They don’t stop the work unnecessarily.
They simply:
confirm instructions
record changes
track labour
note disruption
issue notices
create evidence
Quietly.
Professionally.
Consistently.
📋 The Email That Protects Margin
One of the most powerful commercial habits is this:
After a verbal instruction, immediately send:
“Further to today’s discussion on site, we confirm instruction to…”
That one sentence:
creates timeline
creates evidence
creates accountability
creates commercial visibility
And importantly:
it gives the other side the opportunity to correct you if they disagree.
Most don’t.
That silence becomes valuable later.
⚠️ The “We Didn’t Instruct That” Problem
This usually appears near the end of the job.
Especially when:
budgets are blown
variations are large
margins are under pressure
The contractor may suddenly argue:
it was included
it was foreseeable
it formed part of coordination
it wasn’t formally instructed
there’s insufficient evidence
At that stage, subcontractors often rely on:
memory
conversations
goodwill
Meanwhile the contractor relies on:
paperwork
contract process
technicality
evidence gaps
Guess which one usually carries more weight commercially?
🧾 The Dangerous Phrase
Be careful when you hear:
“Don’t turn this into paperwork.”
Because in construction:
paperwork is often the only thing separating a variation from free work.
🧠 The Commercial Reality Nobody Likes
The subcontractors who recover the best variation accounts are not always:
the best tradesmen
the loudest people
the most aggressive firms
They’re usually:
the ones with the cleanest records.
Because construction final accounts are often won or lost long before the final meeting happens.
They’re won:
in emails
in notices
in labour records
in confirmations
in daily reporting
That’s where entitlement is built.
🧾 Week 2 Checklist
Ask yourself honestly:
Are verbal instructions becoming normal on our jobs?
Are we confirming changes in writing quickly enough?
Are labour and disruption impacts being tracked properly?
Could we prove the difference between original scope and changed work?
Would our evidence survive a final account argument six months from now?
If not, the risk is already building quietly in the background.

🛡 Need Your Tender and/or Contract Reviewed Before You Sign?
Many of the problems I write about each week start before the job even begins; when contracts are signed without a proper commercial review.
Through APS (SW) UK – Tender & Contract Risk Shield™, we provide practical pre-contract reviews designed to help subcontractors and contractors:
✔ Identify hidden commercial risks
✔ Spot unfair clauses before signing
✔ Understand the real liability position
✔ Protect cashflow and margin from day one
These reviews are straightforward, practical, and affordable; designed for real construction businesses, not just large corporates.
