You may need to apply for planning permission to fit new UPVC windows, including double glazing, in your flat, as this can affect the look of the wider building.

In many modern apartment blocks, double glazing will have been fitted during the construction process, and any replacement may be complex and require the consent of the developers or property management company.  

If it is possible to fit double glazing or replacement windows in your flat, the process will be the same as with any other property.  Windows are usually fitted from the inside out, although some exterior finishing work may be required, and this can complicate the process and affect the final price of the project.  For more information about fitting double glazing in a flat, please contact one of our local installers who will be able to provide you with more information and a quote for the work.
