The Planning Permission Lie – When Builders Say “It’s Fine” (But It’s Not)

How the Scam Works

Rogue builders use this trick to rush jobs through without delay, cost, or scrutiny.
They don’t want Building Control or planning officers turning up and spotting their shortcuts.

So they tell you:

“It’s just a minor change.”
“You’re under permitted development.”
“We do these all the time — never needed planning.”

Then, once the job’s done (and they’ve been paid), the truth surfaces:
The work breaches planning rules — and you’re the one in trouble.

The Fallout

🚩 The council orders you to apply for retrospective planning permission (which can be rejected).
🚩 You could face fines or enforcement action.
🚩 You may have to demolish or alter the structure at your own cost.
🚩 Your property’s value and insurability take a serious hit.

And the builder?
Gone.

Why It Happens

Because rogue builders know most homeowners don’t understand planning law — and they use that to their advantage.
They’d rather get the job done quickly and take the money than follow the rules and risk inspection.

How to Protect Yourself

✅ Never take a builder’s word on planning or Building Control.
✅ Check your project with your local council planning department or the Planning Portal.
✅ Get written confirmation before work starts.
✅ Keep copies of approvals or correspondence — they’re your protection.
✅ Use verified builders through Check A Builder, where compliance isn’t optional.

A real professional welcomes regulation — because they know their work can stand up to it.
