Why Green Belt matters
If your site lies within the Green Belt, strict planning controls are in place to protect open land from urban sprawl. Development is heavily restricted, and proposals must meet specific exceptions or demonstrate very special circumstances to gain approval. Knowing this early helps you avoid wasted applications, plan viable projects, and focus your search on sites with real potential. 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.
One postcode is a start. Now do it at scale.
This tool answers one question about one location. Data Studio puts 150+ planning and constraint layers over any site you are looking at, alongside ownership and sales history.
