Do I Require Planning Permission For New Windows?

There are a number of reasons why you may want to make external changes to your home. While some individuals may be performing basic maintenance, others may be looking for ways to make their home more energy efficient.

Either way, windows and window frames are frequently replaced. If you are in the process of maintaining and even improving your home, then there are several things you will have to figure out before starting the process.

One of the most pressing questions you will need to answer is whether or not you require planning permission for new windows. Let’s take a moment to fully examine this question.

Short Answer

Not usually, unless the building in question is listed.


According to UK building codes, you will not need planning permission if you are maintaining, performing minor improvements, or are repainting windows and window frames.   Due to the amount of work an average house requires, there is no permission required for this work. Things become a little more complicated however when you are outright replacing the window.

If you are replacing a window and window frame with one that has a similar appearance to the original window and window frame that came with the house, then you do not require planning permission – unless you live in a listed property, in which case you always require listed building content. So, for example, if you wanted to install a new bay window, then you would require planning permission. If you want to simply replace what is there with a similar looking model, then you are fine. Remember that any new windows will have to comply with the current UK building codes. This includes things like thermal heat loss, safety glazing, ventilation, and fire safety.

Ask your window provider about these requirements. They will be up to date with all building codes and will be able to instruct you on how you can best get the look you want while meeting building requirements as well as your budget.

All of this does not apply if your building is on the Statutory List of Building of Special Architectural or Historical Interest. Designed to protect the very best and most iconic in British architecture and design, listed buildings require planning permission for a whole host of changes, including new windows.

Thankfully, the majority of homes in the UK are not listed.
