The question it answers

“Is my builder's quote realistic?”

A quote is a single number with a great deal hidden inside it. Tender Intelligence opens it up — every trade section set against the benchmark, the over-priced lines flagged, and the items that should be there but are not.

Where it sits

Before you sign anything.

You have a quote in hand and no easy way to tell whether it stands up. This is the report that checks it — so you go back to the builder knowing exactly which lines to question, and what the work should actually cost.

It does not replace getting the work priced. It tells you whether the price you have been given holds.

Inside the report

What sits in your eight-to-ten pages.

01

The Verdict

The quote against the benchmark — fair, over or under, and by how much. The thirty-second read.

02

Line by Line

Every trade section of the quote set against live cost data, rated, with the variance shown. Where the value sits.

03

The Flags

The specific lines to put back to the builder — the ones priced high, and the ones missing entirely.

04

Property Intelligence

EPC, Land Registry and flood data for the property — the same grounding as the cost reports.

05

Guidance & Advice

What to do with the findings, and how to take them back to the builder with confidence.
