Why Flood Zone 3 status matters
If your site falls in Flood Zone 3, it’s considered to have a high probability of flooding from rivers or the sea. Development is still possible, but you’ll almost certainly need a detailed Flood Risk Assessment, strict mitigation measures, and potentially design adaptations, all of which can significantly affect costs and timelines. Knowing early helps you plan smarter, budget accurately, and avoid costly surprises. You can learn more here.

What site sourcers, land agents and developers say about BOOM!
The same data, a fraction of the price
Searchland, LandTech and Nimbus charge an average of £3,540 a year. BOOM! is £540 a year with every add-on included, or £216 for the sourcing data on its own — the £20 a month plan, billed annually.
That is £3,000 a year back into your next deal.
We can charge less because we cost less to run: a small team, no sales force, and no venture capital demanding a price rise every year. The platform is also only part of what we do — the others sell a sourcing platform and nothing else.
