Planning Permission Jersey

The right window for a conservation area property in Jersey.

Replacement windows in Jersey conservation areas — planning permission guide.

In a Jersey conservation area, replacement windows need planning permission where they can be seen from a road or the foreshore — and that permission turns on whether they respect the character of the street. Windows at the back, out of public view, can be replaced without an application. We handle the application, the heritage statement and the window specification where one is needed.

What's Included

How It Works

1

Consultation

We confirm conservation area designation and advise on appropriate window materials and styles.

2

Application

We produce planning drawings and submit the application with any required heritage statement.

3

Specification

We specify windows in materials appropriate to the conservation area.

Planning Note

Class F of the General Development Order allows replacement windows without permission, but not in a conservation area where the work is visible from a road or the foreshore. For those windows you need permission, and the Planning Department assesses material, style and proportion against the character of the area.

Alterations & Windows we have taken through planning

Listed Window Replacement

“Replacing the old windows on our cottage in St Ouen felt like a legal minefield. The team sorted out the historic environment details and drawings without any fuss, and the planning department approved the slimline double glazing on our first attempt.”
Jean Le Brun, St Ouen

Solar Panel Array

“We wanted in-roof solar panels on a roof facing the street in St Helier. Planning initially pushed back, but the team handled the submission brilliant and won the approval for us.”
Sophie Marett, St Helier

First Floor Glass Balcony

“We were worried a glass balcony on our first floor would trigger privacy complaints from next door. The architectural team designed frosted side panels into the drawings, which satisfied the planning officer straight away.”
Emma Le Quesne
