Cheaper than a Quantity Surveyor
Why builders switch01
The alternative to the £1,000 quantity surveyor call.
On a £90k extension, a full quantity surveyor is overkill — but pricing it by hand still eats a Friday afternoon. QuoteWise sits in between: an estimating service that reads your drawings and returns a priced, defensible quote for a fraction of QS fees, so you can bid more jobs without adding a surveyor to the payroll. Pricing a tender? Send the pack — you get the take-off done and a priced bill of quantities (BoQ) back, every line editable.
How the service works02
From drawings to a quote. In three steps.
01upload
drop · pdf · jpg · png01 / 03Your drawings
Send the drawings.
PDF, JPG or PNG — plans, sections, elevations, schedules, full tender packs. Anything you'd hand to a QS, up to 25 MB an upload.
02review
assumptions · flagged02 / 033 items need clarification
Talk through the gaps.
Every assumption that needs a builder's call — foundation depth, glazing spec, finish level — is flagged for you to confirm or override. It never guesses.

Send it as your quote.
You get a priced, line-by-line quote — every quantity, rate and assumption visible — as a branded PDF you can put your own name on.
How accurate it is03
Around 80% accurate on complete drawing sets.
~80%
Measured, not claimed.
On complete drawing sets, QuoteWise scores around 80% accuracy against expert-checked baselines. It's a working draft — not a fixed price. Planning-only drawings score lower, and every assumption is flagged so you can correct it.
2,000+
Tested on real UK jobs.
That accuracy is measured across 2,000+ test runs on real UK projects — extensions, lofts and conversions — not a demo dataset built to flatter the numbers.
12 m
A quote in minutes.
12 m median estimate time, so you can turn a drawing into a defensible number the same day it lands — not next week.
10×
A fraction of QS fees.
Roughly 10× cheaper than commissioning a quantity surveyor for the same early-stage pricing on a domestic job.
When to hire a QS instead04
We don't pretend to replace a quantity surveyor.
QuoteWise replaces the £1,000 QS call on a domestic extension, where a full surveyor is overkill. For commercial work, large refurbishments, or anything with serious risk or contractual weight on the line, hire a real QS — and use QuoteWise to prep the brief. Plenty of surveyors use it that way too: a fast second set of eyes on a quote, not a replacement.
