Replacing Windows In A Conservation Area: What You Need To Know
When you live in a conservation area, you must follow specific rules when it comes to changing the exterior of your property. This includes changing your windows.
These rules are in place to protect and preserve the character of older properties in the UK. Knowing where you stand and exactly what rules you must follow can be confusing.
Our guide to replacing windows in a conservation area contains information on staying compliant, as well as some tips on choosing the right windows to comply with local regulations.
What Is A Conservation Area?
A conservation area is a patch of land set out by local authorities as containing ‘unique historic or architectural features that warrant preservation’. Therefore, for an area to be deemed a ‘conservation area’, local and regional standards must be met.
This includes very stringent planning laws set out by the Local Planning Authority, who will manage all aspects of the conservation area, including processing planning applications and signing off developments within the zone.
Due to the historical nature of a conservation zone, any changes will be highly scrutinised to ensure that any alterations made do not damage the special historical qualities of the area. At least, the changes must maintain this charm.
What Is Article 4 and How Could It Affect My Home?
Article 4 directions are a key part of conservation area regulations throughout the UK. Through these directions, changes that are made to windows must reflect the original character of the building. Failure to follow these directions can lead to declined planning permissions.
Issued by local authorities under the Town and Country Planning Order, the Article 4 directions will remove typical ‘permitted development rights’, and therefore, homeowners cannot make changes to their property without planning permission. The most common aspects of a property that will be affected by Article 4 are the windows, doors, roofs and facades.
Even a small change will require planning permission under these Article 4 directions, as they aim to prevent alterations that could largely affect the character of the conservation area.
This means that there are a few restrictions in place when it comes to window replacements, including:
- Replacement windows must replicate the original material, detailing and style to stick with the property’s period,
- The size and shape of the windows must remain consistent with the original, including depth, width and height. The number of panes and glazing bars must also stay the same.
The best way to comply with these Article 4 directions is to contact your local planning authority, inform them of your plans, and they will be able to further inform you of any specific rules in place that you must be aware of.
Can Windows Be Replaced In A Conservation Area?
As mentioned above, windows can be replaced in a conservation area; however, you must ensure that the windows you choose are suitable for the area.
In most cases, you must meet your local planning authority’s specifications and design requirements. However, with various window styles and configurations on the market, you’ll find one that fits your needs.
When working on a historic or period property that is listed, listed building consent will be required to get permission to make alterations and improvements. Be sure to take a look at our Considerations & Guide to Upgrading Historic & Listed Buildings, where we go into more detail.
Will Planning Permission Be Required To Replace Windows In a Conservation Area?
As a conservation area has strict planning laws, planning permission is required to replace windows. Whether you’re installing double glazing to make the property more efficient, or the existing windows are looking worn and require replacement, all this work needs planning permission.
To obtain planning permission, an application must be submitted to the Local Planning Authority, including drawings, photographs and measurements as supporting documents. If any neighbouring properties may be affected by the changes, they must provide a letter of consent.
Your application will then be assessed against various criteria, including the impact the changes will have on the character of the conservation area, and whether they could affect the protected factors.
How Does The Planning Process Work?
To gain approval for your new windows, careful planning and liaison with local authorities is advised. This will likely make your approval process smoother.
Take time to research your local guidelines with the government’s planning map data, where you can check rules in your specific area.
If you are feeling a little concerned about applying for planning permission yourself, it’s best to ask an expert for advice. Our team are happy to help you with navigating and installing new windows, and can source more specialist products to emulate the style of more traditional designs.
What Does The Approval Process Consist Of?
Once you’ve submitted your application, your local authority will review it to ensure that everything is in line and compliant. The application is checked for accuracy and completeness before moving on to the consultation period, where your neighbours may be asked for comment on the proposal. Once the consultation period is over, a conservation officer may visit the property to assess the condition of the current windows and how well the replacements could fit into the existing area. Finally, the local authority will either accept or deny the application, based on how well the proposal aligns with the conservation rules.
If your application is approved, you’ll receive formal consent. This means that you can proceed with the replacement.
Can I Install New Windows Without Planning Permission?
What Types Of Windows Are Allowed In A Conservation Area?
Windows installed in a conservation area must fit in with the right style and material.
Are uPVC Windows Allowed?
Typically, uPVC windows are allowed in conservation areas; however, the colour and style must fit with your home and others in the area. Therefore, extras such as Georgian bars and mock sash horns are required for uPVC windows to qualify.
UPVC sliding sash windows imitate period sash windows, fitting with Victorian, Edwardian and even Georgian designs. Choosing a uPVC sash window means modern security features and energy ratings, making your property safer and more efficient.
Sometimes, uPVC casement and flush casement windows can qualify under Article 4. This approval will depend on the area and the Local Planning Authority. As with all window types, approval will depend on colour, configuration and decorative details.
What’s The Best Method Of Choosing New Windows in A Conservation Area?
When replacing windows in a conservation area, the general rule is to replace the existing windows as closely as possible. This does not mean that you cannot have more modern, energy-efficient windows, though.
Speaking to a window expert, such as Homeglaze, will unlock a vast knowledge of the right windows for a conservation area, and how to fully emulate the style and finish of the existing windows on the property. They’ll be able to help you strike the right balance between modern and traditional, without losing the charm of the conservation area.
