Do you need permission for a basement conversion in Leominster?

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

Converting an existing cellar with no external changes usually does not need planning permission in England.

What can change the price or programme?

  • New basements nearly always involve the Party Wall Act in England and Wales.
  • A pump for the drainage system needs a battery back-up.

What happens after I enquire?

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  2. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
