Do I need planning permission to convert a cellar?

Most cellar conversions don’t need planning permission if you’re converting an existing space.

However, if you’re excavating deeper, changing the external appearance, or creating a new entrance, you’ll likely need permission and Building Regulations approval.

Contact your local authorities as a first port of call.

Is a cellar conversion worth it?

Yes – converting a cellar can add valuable living space and increase the property value. It’s also a great option for homeowners in areas where extending upward or outward isn’t possible.

Basements and cellars are legal in the UK, but the work must comply with UK Building Regulations.

This ensures the conversion meets industry-standard requirements for damp proofing, ventilation, fire safety, and structural safety.

Can you convert a cellar into a bedroom?

Yes - with the right planning and building work, you can convert a cellar into a bedroom, guest suite, or even a self-contained studio.

To meet building regulations, your cellar bedroom will need:

  • Proper ventilation and insulation
  • A safe fire escape route
  • Adequate ceiling height and natural light
  • In some cases, planning permission

These checks aren’t just for comfort - they’re essential if you ever decide to sell your home. A compliant conversion can add value and avoid issues during surveys or legal checks.
