When planning to install double glazed windows in a home there are a number of things to consider. One of first things to ask oneself is: Do I need planning permission to install double glazed windows in the first place? The answer is "yes". And the answer is "no". Its not that confusing though and if can be easily discerned.
When permission is not a requirement: In more cases than not a person will not need to seek approval to install the double pane windows. The changes and construction to the house is minimal and will usually have little effect on the neighbors. Nor is the work likely to overstep any bounds or steps into associations or city planning requirements. It is also highly unlikely that this kind of installment will be regulated as these windows are more fuel and energy efficient.
When permission is needed: However, there are always exceptions to the rules. While approval is not usually needed for installment in homes or residences used as dwellings larger buildings may be another story. Of course if you are renting flats or apartments than most likely you will require authorization and in allot of cases this will be difficult to get. Other exceptions that may require allowance are office buildings, hotels, commercial and community buildings.
Lastly, some homes and residences are built or suddenly placed in a conservation area as deemed by a government agency. These conservation areas are under high scrutiny when any kind of work is done to areas within them.
Uniquely, about this last point. There are certain situations that may or may not help you. Local citizens may be polled and depending on how well liked or not a person is could play a role in the decision. This also provides the propose to "sell" their plan to neighbors.
So when asking, "Do I need planning permission to install double glazed windows" just know that the answer many not be cut and dry. Make decisions and plan based on knowledge and understanding of the rules.
