Subcontract final accounts have the same structure as main contract accounts and behave quite differently in practice. They are smaller, they settle later, and the subcontractor frequently has less information and less commercial weight. Those differences shape how a final account dispute review approaches one.
The underlying work is the same: reconcile, schedule the disputed items, establish the basis for each. What changes is the leverage and the timing.
Why they settle late
Because the contractor is frequently waiting on its own account above, and nobody wants to settle below until they know what they are recovering.
Because the subcontract account is one of many, and the contractor’s commercial team is working through them in order of size or noise.
And because a subcontractor pressing for settlement has fewer levers than a contractor pressing upwards, which is simply how the chain works.
The pay when paid question
Arrangements making payment conditional on the contractor being paid are restricted in the United Kingdom, subject to limited exceptions, and whether a particular clause is effective is a legal question.
What is clear commercially is that the subcontract has its own payment mechanism with its own dates, and that mechanism operates on its own terms.
Informal versions of the same idea, where payment is promised when the money arrives from above, carry no contractual weight at all.
Information the subcontractor does not have
The main contract, the instructions issued under it, and the correspondence that explains why work was varied or delayed.
That asymmetry matters when a subcontractor is being told that a variation was not instructed or that a delay was its own fault.
Asking for the relevant documents is reasonable and frequently productive, and refusing to provide them is itself a position worth noting.
Contra charges downwards
Subcontract accounts carry more contra charges than main contract accounts, and they are more likely to have been applied without the notice the subcontract required.
Each one should be examined on both counts: whether it was notified properly and whether it is supported by evidence.
A deduction applied late or without support is exposed regardless of whether the underlying complaint is justified.
Attendance, access and the things nobody prices
Subcontract disputes frequently involve what the contractor was supposed to provide: scaffold, power, hoisting, access, welfare, attendance.
Those obligations are in the subcontract and they are rarely recorded when they fail, which makes the eventual claim difficult.
Recording at the time that promised attendance was not available is one of the highest value records a subcontractor can keep.
Where the leverage actually is
Retention, which the contractor holds and which eventually has to be released, and which provides a reason to engage.
Ongoing work, where the relationship continues and a contractor wants the subcontractor back.
And the payment mechanism itself, which operates whether or not the contractor is ready to settle the account.
Closing one properly
Reconcile the subcontract sum to the account in the same way as any other, with the variations, remeasurement and deductions shown separately.
Address the contra charges individually rather than as a block, because they will have different answers.
And deal with retention explicitly, since it is frequently the last item and the one most likely to be forgotten by both sides until long afterwards.
From the contractor’s side
Settling subcontract accounts promptly is commercially sensible, because an open account occupies attention and sours a relationship you may need.
It also protects the main account. A contractor claiming for disruption upwards while refusing the same claim downwards is in an awkward position if both are examined.
Consistency between what is claimed above and what is allowed below is worth checking before either is submitted.
When the contractor is in difficulty
Where the contractor above is under financial pressure, the commercial calculation changes and speed matters more than margin.
Retention held by a party that may not survive is worth considerably less than retention released, which is a reason to press rather than to wait.
That is a commercial judgement rather than a contractual one, and it is worth making deliberately.
Variations instructed by nobody
Subcontract variations are frequently instructed verbally by a site manager under time pressure, with no written confirmation at any level.
The subcontractor then claims for work the contractor cannot find an instruction for, and the contractor cannot recover it upwards either.
Both parties lose, which is why confirming subcontract instructions in writing protects the contractor at least as much as the subcontractor.
Programme and the sequence given
A subcontractor prices a sequence and frequently works a different one, because the project moved around it.
Whether that carries an entitlement depends on what the subcontract said about programme and about the information the contractor was to provide.
Recording the sequence actually worked, against the one priced, is the evidence that makes such a claim possible at all.
Final accounts in a chain
A main contractor frequently cannot settle below until it knows what it is recovering above, which is understandable and not a contractual answer.
The subcontract account stands on its own terms, and the subcontract mechanism operates whether or not the account above has been agreed.
Saying that plainly, early and without hostility is usually more effective than waiting to see what arrives from above.
Where it sits
A subcontract account in dispute is the same exercise at smaller scale, and the proportionality question matters more because the sums are smaller.
Where the issue is a single payment cycle or a retention balance, the narrower payment review or retention recovery assessment usually fits better than a full account review.
The discipline that prevents most of it is the same as everywhere else: value change as it happens, notify properly, keep records. That is cost control and variations work.
Final account stopped moving?
A final account dispute review reconciles the account, sets the disputed items out on a schedule with their basis and evidence, and gives a view on where the gap can realistically be closed.
