License to Alter


Leaseholders as defined under section 20 of the Party wall etc. Act 1996 (the Act) must obtain a Licence to Alter before modifying their property, depending on the proposed development works. The most common requirement is for a loft conversion.  

The licence allows freeholders to protect themselves against potential losses, damage to the fabric of the property and ensures the works will not adversely affect other leaseholder or residents in the building.

In most cases, freeholders should consent to the proposed alterations provided the leaseholder agrees to reasonable terms. There is then no need to execute the Act.

Obtaining a Licence to Alter can often be a drawn-out and complicated process, but you can trust our Certified surveyors to make it as straightforward as possible.

Examples of development works that require a Licence to Alter are:


  • Structural alterations, removing load bearing wall or inserting Steel beams to support.
  • Sanitary facility installations and modifications.
  • New heating installations.
  • Wall removals and modifications.
  • Window replacements especially relevant if in a conservation area.
  • New opening formations.
  • Loft Conversions.
  • Basement excavations.
  • Extensions.
