Not because it is cheapest. It currently reads most complete against the same plans and inclusions.

Custom coastal home quote comparison
This dummy comparison shows how ScopeFrame explains three builder quotes against the same job files before a homeowner signs.
The lower total depends on scope that still needs a plain written yes or no.
Ask the written questions before treating the totals as equivalent.
Prices
Three quotes, one project file set.
Builder A: Reasonable wording, but still needs confirmation around site assumptions and allowances.
Builder B: Lower headline price, but drainage, spoil, structural steel and thermal wording are too soft.
Builder C: Not the cheapest, but currently reads most complete against the same document pack.
Category by category
Where the quotes line up, and where they do not.
| Category | Builder A | Builder B | Builder C |
|---|---|---|---|
| Site and preliminaries Builder B still leaves more room around preliminaries, temporary works, and site assumptions. | Mostly covered | Needs clarification | Stronger coverage |
| Structure and engineering Builder C reads most clearly against the engineering set, especially on structural interfaces. | Partly covered | Unclear | Best aligned |
| Drainage and stormwater This remains one of the easiest areas for expensive gaps to hide between drawings and quote wording. | Clarify | Risk of omission | More clearly included |
| Insulation and thermal Thermal notes should be clarified against the project location and climate-zone context before commitment. | Confirm final schedule | Location basis unclear | More clearly stated |
| Finishes and inclusions Builder B still relies more heavily on allowances where the inclusion level matters. | Reasonable fit | Allowance-heavy | Cleaner alignment |
| Allowances and provisional sums This is where cheaper-looking quotes can drift once the build is underway. | Some exposure | High exposure | Lower exposure |
What we found
Issues that can change the real price later.
Stormwater collection, disposal and legal connection
Written clarification neededIf the stormwater lane is not fully included, the comparison can look cheaper now and more expensive once site works start.
Dummy evidence sourceBuilder B quote
Structural steel supply, fabrication, delivery and install
Too soft to trust at face valueThis is a category where one ambiguous sentence can hide a large real cost difference.
Dummy evidence sourceStructural engineering drawings
Excavation spoil removal and disposal
Looks optimisticA thin allowance here can become a fast variation once real site volume is known.
Dummy evidence sourceBuilder B quote
Temporary works, access support and site protection
Cleaner in the stronger quoteWhen temporary works are fully owned in the quote, the homeowner is less exposed to surprise site-setup conversations later.
Dummy evidence sourceBuilder C quote
Insulation values and climate-context alignment
Clarify against the actual locationThis is not a formal compliance check, but it is exactly the kind of practical question worth resolving before signing.

Before you sign
Questions to ask the builders in writing.
- Can you confirm in writing that stormwater collection, disposal and final connection are fully included in the quoted sum?
- Can you confirm whether structural steel supply, fabrication, delivery and install are fully included, with no separate allowance or exclusion?
- Can you confirm how excavation spoil removal has been allowed for, including cart-away and disposal assumptions?
- Can you confirm the insulation values and thermal basis you priced against, given the stated project location and intended build standard?
- Are there any temporary-works, access or site-protection assumptions that could move the quoted total later?

Suggested message
Hi Builder B,
Thanks again for the quote. We are comparing the builders against the same plans, engineering and inclusions pack and wanted to clarify a few items in writing before moving further.
Could you please confirm whether stormwater collection, disposal and final connection are fully included in the quoted sum, whether structural steel supply, fabrication, delivery and install are fully included, and whether excavation spoil removal has been fully allowed for including cart-away and disposal assumptions.
If there are any site-access or temporary works assumptions that could move the quoted total later, please note those as well.
A written response is appreciated so the comparison stays clean across the same project pack.
Thanks,
