How It Works
Consultation
We confirm whether your replacement windows need planning permission based on your property type, zone, and proposed window specification.
Application
We submit the planning application where required.
Specification
We specify windows to meet Jersey bye-law U-value requirements in the drawings.
Planning Note
Replacement windows in standard residential areas may fall within permitted development if they match the existing in appearance. Conservation areas and listed buildings have stricter requirements. We always confirm before proceeding.
Frequently Asked Questions
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.”
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.”
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.”
