What is included in a basement conversion in Salford?

A basement conversion turns an existing cellar into dry, usable rooms, or excavates a new basement under a house. Converting an existing cellar is far simpler and cheaper than digging a new one, and often does not need planning permission.

  • Damp and structural survey
  • Waterproofing design and installation
  • Finished floors, walls and ceilings

How much does a basement conversion cost in Salford?

Basement and cellar conversionsGuide price incl. VAT
Existing cellar conversion£1,900 to £3,000 per m²
New basement excavation£4,200 to £6,600 per m²

Do you need permission for a basement conversion in Salford?

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. Digging a new basement or adding a lightwell often does, and many councils have basement policies.

What can affect a basement conversion?

  • Groundwater levels drive the waterproofing design and cost.
  • Headroom of about 2.1 m or more is needed, which may mean lowering the floor.
