Planning Permission for Window Replacement in Edinburgh — What You Need to Know

Edinburgh has some of the most stringent planning requirements in the UK. Here's what you need to know before replacing windows in a listed building or conservation area.

Do you always need planning permission?

Not always. In many cases, replacing windows in a standard residential property falls under "permitted development" — meaning no planning application is required. However, there are significant exceptions in Edinburgh.

Listed Buildings

If your property is Category A or B listed, you need Listed Building Consent for any alterations to the external appearance — including window replacement. This is separate from planning permission and is required even for like-for-like replacements.

Edinburgh City Council's conservation officers will assess any proposed changes. They will typically require:

• Like-for-like replacement of existing profiles and mouldings
• Matching timber species and finish
• Heritage-appropriate glazing (often slimline double or Fineo vacuum glass)
• Retention of existing ironmongery or matching replacements

Conservation Areas

Edinburgh has extensive conservation areas covering much of the New Town, Old Town, and surrounding Victorian suburbs. Within these areas, "Article 4 Directions" remove permitted development rights — meaning you need planning permission for window changes that would otherwise be exempt.

If you're unsure whether your property is in a conservation area, check Edinburgh City Council's online planning portal or contact their duty planning officer.

The Pre-Approved Route

We are pre-approved by Edinburgh City Council as a supplier of heritage glazing units. Our products and specifications have already been assessed and approved for use in listed and conservation area properties across the city.

This significantly speeds up the approval process for projects involving our products — conservation officers don't need to assess the product itself, only its application in your specific property.

Our Advice

• Always check listed building and conservation area status before ordering windows
• Submit a pre-application enquiry to the planning authority if you're unsure
• Allow 8–12 weeks for Listed Building Consent applications
• Use a pre-approved supplier to speed up the conservation officer's assessment
• Secondary glazing rarely requires consent and is often the fastest route
