Omissions are works from a quotation or construction contract that are ultimately not performed, reduced or simplified. Think of painting you decide to do yourself, a cheaper material, fewer square metres of tiling or removing an entire item. The value is deducted from the contract price.
Important: omissions are not an automatic refund of the amount once listed in the quotation. They are an adjustment to the scope. How much is credited depends on the original specification, timing, incurred costs and the contract terms.
What counts as omissions?
Omissions occur whenever the agreed performance becomes smaller than what the contractor priced. This can happen in three ways:
- Work is removed completely: an item is not performed, such as no outdoor tap or no painting.
- Work is reduced: fewer metres, quantities or hours are needed than budgeted.
- Work is simplified: the item remains, but with cheaper material or a simpler finish.
In every case, it must be clear which item changes. Without a concrete description, a dispute will arise over what exactly should be removed from the price.
Why don't you always get the full amount back?
The price in a quotation consists of more than labour and material. It often also includes work preparation, procurement, coordination, mark-ups, overhead and margin. If you instruct omissions after the contractor has already prepared the work, the contractor may argue that part of those costs has already been incurred.
That is why the question is not only: "What was listed for this in the quotation?" The better question is: "Which costs genuinely disappear, and which costs have already reasonably been incurred?"
A fair credit starts with the original price, but corrects for demonstrable costs that can no longer be avoided. The later you notify omissions, the smaller the chance of a full credit.
How to calculate omissions in practice
Preferably use a simple calculation that both parties can follow:
- Start with the price of the original item or the agreed unit price.
- Determine which part of labour, material and subcontracting is no longer required.
- Deduct demonstrably incurred or unavoidable costs.
- Check whether the amount includes or excludes VAT.
- Record the balance in writing as a change to the order.
Example: the quotation includes 20 m2 of tiling at €85 per m2. You remove 6 m2 before materials have been ordered. The logical basis for the omission is then 6 x €85 = €510. If the tiles have already been custom ordered and cannot be returned, the amount may be lower.
How do you prevent disputes?
Most disputes about omissions are not caused by the removal itself, but by vague quotations. An item such as "complete bathroom: €12,500" gives little guidance. A specification with quantities, unit prices and material choices makes credits much easier.
Therefore agree in advance on:
- Unit prices: price per m2, item, hour or component.
- Notice periods: until when omissions can be instructed without additional costs.
- Settlement: when the amount is processed, for example in the next instalment or final account.
- Variations and omissions: price both separately before offsetting one against the other.
Practical tip: always confirm omissions by email before the work would start. Mention the item, quantity, agreed amount and whether the amount includes or excludes VAT. A short confirmation prevents a long dispute later.
Omissions versus variations
Omissions are often discussed at the same time as variations. That is practical, but also risky. If additional work and removed work are offset immediately without substantiation, you lose insight into the real prices.
Therefore have the variation priced separately and the omission credited separately first. Only then should you settle the balance. This keeps visible whether the contractor calculates fairly on both sides.
Conclusion
Omissions are a normal change in a construction project, but they require precise documentation. If you work with clear specifications, unit prices and written confirmations from the start, removed work is less likely to lead to disputes or unexpected costs.
Frequently Asked Questions about Omissions (Less Work)
What are omissions?
Omissions are items from the quotation or construction contract that are ultimately not performed, reduced or simplified. Their value is credited as an adjustment to the contract price.
Do I always get the full amount back for omissions?
No. The credit depends on the quotation, contract terms, timing and costs the contractor can prove have already been incurred. Clear unit prices prevent most disputes.
How should omissions be recorded?
Confirm in writing which item is removed, from what date, which amount is credited and whether the amount includes or excludes VAT. Have the contractor confirm this before the work would start.
