Frequently asked questions

How long does a planning decision take in Watford?

The median time from submission to decision for home project applications decided in Watford in the last 12 months was 54 days (about eight weeks). Times vary case by case.

Do I need planning permission in Watford?

It depends on the project and the property. Many home projects fall under permitted development rights, but constraints such as conservation areas, listed buildings and Article 4 directions change what needs permission at a specific address. See our guides to permitted development rights and Article 4 directions.

Do I need a planning consultant in Watford?

Many home projects do not need one. A straightforward extension on an unconstrained property is often handled directly with the council, or with an architect or agent preparing the drawings. A consultant is more likely to earn their fee where the site is constrained, the council has refused similar schemes, or an appeal is in prospect. Understanding your property's constraints and the council's recent decisions first makes any conversation with a professional a better-informed one.
