Living in one of York's conservation areas is a joy, but it comes with a responsibility to keep the look of the street. The good news is you no longer have to choose between the character of a period home and the warmth of modern glazing. Heritage-style frames, including aluminium French windows that are UK made and FENSA approved when fitted, let you have both. Here is how to get it right.
Why conservation areas are different
Conservation areas exist to protect the character of a place, and York has several. That usually means there are limits on what you can change on the parts of a house that can be seen from the street, including window style, materials and sometimes colour. The rules vary from street to street and can be stricter on listed buildings.
Before you change anything visible, check what applies to your property. City of York Council is the authority for consent and conservation matters, and the requirements do change, so confirm the current position with them rather than assuming. It is far cheaper to ask first than to unpick work later.
What heritage glazing needs to do
The aim is windows that read as traditional from the pavement but perform like modern ones behind the scenes. In practice that means:
- Slim sightlines so the frames look period-correct rather than chunky.
- The right glazing bars and proportions to match the original design.
- Discreet, colour-matched finishes rather than glossy modern white.
- Modern sealed units with low-E glass for warmth, where the conservation rules allow.
Where aluminium comes in
Heritage aluminium has become a popular answer for York homes. The metal is strong, so the frames can be genuinely slim while still holding good glazing, which gets you close to the delicate look of old timber without the constant upkeep. It takes a fine, even factory finish and can be colour-matched to suit the street.
Our heritage aluminium windows and doors are designed with exactly this balance in mind, and our wider aluminium windows range shares the same slim, durable frames. If you want aluminium French windows, choosing a UK-supplied product fitted by a FENSA approved installer means the work is done to standard and the paperwork is there when you need it, which matters when you come to sell.
Timber and timber-look options
For some properties, timber remains the most appropriate choice, and painted timber frames can be the natural fit on the most sensitive streets. Where genuine timber is not required, timber-look finishes on modern frames offer the grain and colour of wood with far less maintenance. Which route suits you depends on the property and what the conservation rules ask for, so it is worth a proper conversation.
Getting the paperwork right
Two bits of paperwork matter here. First, any consent the conservation area or listing requires, which comes from City of York Council. Second, the FENSA or building control certificate that confirms your replacement glazing meets Building Regulations. That certificate is the document a buyer's solicitor will ask for later, so keeping it safe is worth the effort. Rules on both change over time, so check the current requirements before work starts.
What heritage windows cost in 2026
Prices vary a lot with style, size, material and any conservation requirements, so please treat these as guides and get a quote for your home. As of 2026, heritage aluminium windows typically sit above standard uPVC, often from around £900 to £1,600 or more per window depending on size and detail, with timber higher again.

FAQs
Do I need permission to replace windows in a York conservation area?
Often, yes, especially for anything visible from the street or on a listed building. The rules vary by area and change over time, so check the current position with City of York Council before you order anything. It saves a lot of trouble later.
Can heritage aluminium look right on a period home?
It can. Aluminium's strength lets the frames be slim, so they come close to the delicate look of old timber while adding modern warmth. The right colour, glazing bars and proportions make all the difference.
Are aluminium French windows FENSA approved?
The product itself is not certified, but the installation is. When fitted by a FENSA-registered installer, your replacement gets a FENSA certificate confirming it meets Building Regulations. Keep that document for when you sell.
Will new heritage windows make my home warmer?
Yes, where the rules allow modern sealed units with low-E glass, you get a real improvement over old single glazing. On the most sensitive properties there may be limits on what you can fit, so the gain depends on what consent allows.
