Do I Need Planning Permission to Install Double Glazed Windows?

Do You Need Planning Permission for Windows?

Generally speaking, if you're planning to replace your existing windows with double glazed ones, then you won't need to apply for planning permission in most cases. This is because, in the majority of cases, window replacement falls under permitted development rights. However, there are some instances where you may be required to submit a planning application - particularly if you live in a conservation area or listed building. 

In addition to this, certain types of windows may require planning permission, even if you don't live in a conservation area or listed building. If you are planning to install windows that are larger than the existing ones, or if you're installing bay windows or other protruding features on the outside of your house, then this is likely to require planning permission. It's also worth noting that if you live in certain areas of the country, then these requirements and restrictions may vary. 

Do I Need Planning Permission to Change My Windows if I Don’t Live in a Conservation Area?

In most cases, if you're looking to replace your existing windows and you don't live in a conservation area or a listed building, you won't need to apply for planning permission. But there are certain restrictions that you must adhere to in order to ensure that your windows comply with the permitted development rules. For instance, you'll need to ensure that the windows don't protrude more than 15cm from the external walls of your home and they mustn't have a height of more than 1 metre above the floor level. 

If, however, you're planning to install new windows that are significantly different from the existing ones - such as replacing traditional timber frames with UPVC frames - then you will need to apply for planning permission. You may also be required to apply for planning permission if you're planning to install a window in a rear porch, conservatory or similar construction. 

What Happens if I Don’t Apply for Planning Permission?

If you don't apply for planning permission and you proceed with the window installation without permission, then you could face a hefty fine or other penalties. It's illegal to install windows without permission if permission is required, so it's important to make sure that you understand the laws that apply in your area. In some cases, you may be asked to remove the windows if they were installed without permission, so it's also worth considering this when deciding whether or not to apply for planning permission. 

Planning Permission for Windows in Flats – Is it Different?

The rules surrounding planning permission for windows in flats are largely similar to those for other types of property. However, the process is slightly different in certain situations. For instance, if you live in a flat or apartment which is part of a larger block, then you may need to obtain written consent from the landlord or freeholder before making any changes to the windows. 

In addition to this, certain local authorities will insist that the windows are replaced with ones that are in keeping with the overall appearance of the building. This includes the use of specific materials, such as UPVC, and specific designs and colours. If you're unsure whether this applies to your property, it's best to check with your local planning department before proceeding with any window installation work. 

How Long Does A Planning Application Take?

If you do need to apply for planning permission for your windows, then you should typically expect the process to take around 8 to 12 weeks. This time frame can increase or decrease depending on the complexity of your application and the volume of applications currently being processed by the local authority. It's important to note that most planning authorities charge a fee for submitting a planning application - usually between £150 and £400 - and this must be paid prior to the application being considered. 

Before submitting your application, it's worth researching any regulations or guidelines that may prevent you from obtaining permission. If you think that you may run into issues due to the size, layout or design of the windows, then you may need to provide additional information in order to make your case. 

Ultimately, understanding whether or not you need planning permission to install double glazed windows is essential to ensure that you remain compliant at all times. While the rules can vary depending on the type of property and its location, understanding the regulations that apply to your circumstances is the best way to guarantee that everything runs smoothly.
