What Happens After Planning Permission is Granted in the UK?

A guide to non-material amendments, conditions discharge, and planning obligations

Gaining planning permission is a major milestone, but it doesn’t mean the Planning work is finished. Across the UK, most consents come with ongoing planning administration requirements that need to be managed carefully. If they’re not, you could face delays, unexpected costs, or even enforcement action.

This guide explains the key post-planning-consent steps particularly: non-material amendments, discharging planning conditions, and managing planning obligations.

1. Non-Material Amendments (NMAs)

It’s common for projects to evolve after consent is granted — perhaps a change in materials, window placement, or internal layout. Even small tweaks may require a formal non-material amendment application (sometimes called a Non-Material Variation in Scotland).

If you make changes without approval, the local authority may consider them unauthorised development, putting your entire planning permission at risk. Always check with your planning consultant before making alterations.

2. Discharging Planning Conditions

Most UK planning permissions include conditions. Some are “pre-commencement” conditions, which must be satisfied before starting work, while others apply during construction or after completion.

Common planning conditions include:

  • Building materials and finishes
  • Landscaping and tree protection
  • Highways, parking, and access arrangements
  • Drainage and utilities

To discharge conditions, you’ll need to submit the required drawings, specifications, or reports to your local planning authority. Starting work without properly discharging conditions can make your development unlawful.

3. Planning Obligations (S106, Section 75, etc.)

Some permissions come with a legal agreement — known as a planning obligation. In England and Wales these are typically Section 106 agreements, while in Scotland they are Section 75 agreements. These agreements secure contributions or works needed to make development acceptable in planning terms.

They often involve:

  • Financial contributions (e.g. affordable housing, transport)
  • Delivery of infrastructure or public open space
  • Restrictions on use or phasing of development

Missing a deadline or failing to meet an obligation can cause serious legal and project delays. Your consultant can monitor compliance and liaise with the council to ensure obligations are met.

Why This Matters

Post-consent requirements are not optional. They are essential steps to keep your permission lawful and your project deliverable. Neglecting them can lead to:

  • Enforcement action
  • Costly delays
  • Legal risk
  • Loss of planning permission

Best Practice for Developers

To stay compliant and avoid problems if you have a planning consultant or planning manager:

  • Share any proposed design changes with your consultant or planning manager early
  • Provide technical drawings, reports, and specifications when needed
  • Keep your consultant informed about planning obligations and deadlines

By managing these steps carefully, you’ll protect your project and keep it moving forward smoothly.
