Changes to planning obligations

Planning obligations (section 106 agreements) are conditions we sometimes ask for to reduce the impact of a development. They are governed by section 106A of the Town and Country Planning Act 1990

When agreed, planning obligations can be:

  • changed using a deed of modification
  • discharged when:
    • an obligation is no longer needed
    • we agree for it to be modified

How to apply

To apply for a change or discharge of planning obligations, please complete the attached modification form and submit to us via the online contact form in the button below.

Send your application for a change or discharge of planning obligations to 

After you've applied

Once we receive you form, we will:

  • discharge an obligation if it is no longer needed to serve a useful purpose
  • agree to modify an obligation if we consider an it is still needed but can be changed to meet the needs proposed in the application
  • refuse to discharge the obligation if we consider that the obligation still serves a useful purpose

Applicants are expected to pay our legal costs and may need to agree this, in writing, before a decision is made. 

We have eight weeks to decide an application.


You can appeal a decision, or lack of decision, with the Planning Inspectorate. More information is included below.
