Loft conversions in Acton: Homeowners vs renters

If you own your home:

  • You’re responsible for planning, permissions, and hiring.
  • Check if you need planning permission; many lofts fall under permitted development, but not all.
  • Building regulations always apply. A loft conversion without sign-off could cause issues later (including invalidating home insurance).

If you rent:

  • You can’t carry out major work like a loft conversion.
  • Speak to your landlord if you notice issues in the loft space (leaks, insulation problems etc.).
  • If you spot an unregulated loft conversion, flag it with your landlord or letting agent.
