Did you know that, according to Historic England, there are approximately 7,000 conservation areas in England? What makes conservation areas special isn’t just the landscapes, it is also the country houses and model housing estates. If you live in a conservation area, you have a responsibility to maintain the historic aesthetics of your property.
Therefore, if you live in a conservation area and the timber windows in your home need to be replaced, it’s important to do your research. Replacing property windows in conservation areas can have a significant impact on the appearance and aesthetic of your property.

UPVC Windows in Conservation Areas: What to Expect
If you live in a conservation area, your property will be subject to certain restrictions when it comes to renovating or carrying out work. Buildings in conservation areas are covered by certain laws that protect them from any unauthorised work being carried out on them. Many homeowners living in conservation areas are unaware of the restrictions placed on their properties and, as a result, they can unintentionally override the system. This unauthorised work can result in an unlimited fine. Therefore, it is best to stay on the right side of the law and avoid any legal charges by applying for planning permission in advance of any home improvement projects.

UPVC is a popular material and there has been much debate over the benefits of UPVC in comparison with timber. Of course, both have their benefits and if you purchase from South Coast Home Improvements, you will be receiving windows made and installed to the highest standard.

- Enhanced security standards
- UPVC is affordable
- UPVC windows are an attractive incentive for potential buyers.
Can I Fit UPVC Windows in a Conservation Area?
Traditionally, timber sash windows are the preferred choice for properties situated in conservation areas. This is because timber windows add a unique character and improve the value of a period property, making it more desirable.
However, thanks to our expertly crafted UPVCsash windows, you can now replace your old windows with energy-efficient and affordable alternatives. UPVC window replacements are permitted in conservation areas as long as their appearance does not differ considerably from the original window design. Your new windows need to look as close to the original design as possible.
UPVC Window Installations and Considerations to Make

There are many factors to consider when fitting UPVC windows in a conservation area. These include:
- The position of the window within its opening
- The proportions of the sashes
- The thickness and profile of the glazing bars and rails
- The arrangements of any openings
- The material used for the frame
- The thickness and profile of the glass
- The construction of the joints
Plan Your Project Carefully
Replacing windows in period properties with UPVC alternatives in conservation areas is certainly achievable. However, you may have to meet certain criteria in order to secure building consent or planning permission. If all of this goes through, you will enjoy a warmer, more secure, and energy efficient home.
How to Get Planning Permission for UPVC Windows
According to Historic England, any changes made to the external appearance of a property situated in a conservation area may require planning permission from a local planning authority. According to the National Planning Policy Framework (NPPF), conservation areas are of significant historical interest and value and, therefore, any changes to properties must be given great weight in any and all planning permission decisions.
When you apply for planning permission from your local conservation authority, they have a duty to take into consideration your proposed changes and how these updates will benefit the property, while conserving the property’s character.
