A scope of works is a written description of the work being priced: what is included, what is excluded, and what has been assumed. It is the document that turns a number into an agreement.
Why it exists
When you price a job, you make dozens of decisions the client never sees. Which grade of tile. Whether decorating is included. Whether the old patio is lifted and disposed of. Whether making good means filled and sanded or finished and painted.
If none of that is written down, the client's expectations fill the gap — and their expectations are always the more expensive version. A scope makes those decisions visible before the work starts, when they are still cheap to discuss.
What a scope should contain
- A short project description and the drawings it relates to
- The works set out element by element, in build sequence
- Materials and specifications where they are known
- Explicit inclusions — the things people assume are extra
- Explicit exclusions — the things people assume are included
- Assumptions made where the information was incomplete
- Provisional allowances for anything not yet decided
Inclusions and exclusions are the valuable part
The element-by-element description is useful. The inclusions and exclusions are what protect you. Typical items worth stating explicitly:
- Skips, waste removal and site clearance
- Scaffolding and access equipment
- Temporary protection and site welfare
- Decoration and final finishes
- Kitchens, sanitaryware and appliances — supply versus fit
- Floor coverings
- Statutory fees, surveys and party wall costs
- Asbestos, unknown ground conditions and existing defects
How it changes the variations conversation
Without a scope, extra work is a disagreement: the client believed it was in the price, you know it wasn't, and neither position is documented.
With a scope, the same request is a variation. It can be identified, priced, agreed and added. That is not bureaucracy — it is the mechanism by which projects change without anyone losing money or goodwill.
Who should have one
Any builder quoting directly to a private client, because domestic clients have the least understanding of what is normally included. Any contractor passing packages down, so subcontract prices are comparable. Any developer comparing tenders, for the same reason.
A scope prepared alongside your estimate costs very little relative to one argument about whether decorating was in the price. If you want one produced for your next project, send the drawings over.
