The short answer
Yes. Planning decisions may occur post-purchase, making early risk awareness important.
Buying a property doesn't freeze the planning pipeline around it. Knowing what's already in the system, even if it hasn't been decided yet, means you're not blindsided by a decision that lands after you've moved in.
Why this matters for your purchase
The planning constraints section of a PropM8 report surfaces what's already live in the planning pipeline around a property, so you're not relying on hope that nothing changes after you move in.
