How a planning application works

Every application in Hertfordshire follows the same broad path. Knowing where an application has got to tells you whether you can still influence it, and what might happen next.

  1. Submitted and validated

    The council checks the paperwork is complete, then publishes the plans and documents on its planning portal.

  2. Consultation

    Neighbours, parish councils and bodies such as highways are consulted. The public usually has at least 21 days to comment.

  3. Decision

    Most applications are meant to be decided within 8 weeks, and major ones within 13. Bigger or contentious schemes can go to a planning committee.

  4. After the decision

    Permission usually lasts 3 years and can come with conditions. If it's refused, the applicant can appeal to the Planning Inspectorate.

What the numbers can tell you

A busy postcode isn't always a sign of big change. Lots of applications can simply mean homeowners extending, trees being pruned or conditions being signed off. Look at the application type and the description to see what's really going on.

What counts when you comment

Councils can only weigh up planning matters, such as overlooking, traffic, design, noise and the effect on trees or heritage. Loss of a private view or a possible fall in property value usually carries no weight, so focus on the things they can act on.
