I will build a sourced competitor price research spreadsheet

Most competitor price sheets are wrong in a way you cannot see. This one is built so you can check any number in ten seconds.

What you get that a Google search does not:

A source URL and timestamp on every figure. Prices move; without the date the sheet is worthless in a month.

Brokers separated from suppliers. A broker's "from £89.99" is not comparable to a depot's £162.

VAT treated as a real variable. The same 8-yard skip was published at £330 inc VAT, £234.94 ex VAT and £250 with no basis stated a 59% spread on one product.

A summary written for decisions, not data dumps.

Worked example in gallery: a real 8-supplier skip-hire price research pack for Scotland 65 price points, every one sourced and timestamped.

Requirements:

Your market and region (specific "roofers in Glasgow", not "construction")

What you're comparing: product, service, size range, subscription

510 competitors you already know, if any

Will you find competitors I don't know about?

Yes, that's most of the value. I also tell you when a market has almost no public pricing which is itself the finding.

Is this data legal?

Public pricing from public web pages, source cited. No scraping behind logins, no per
