Victorian architecture remains one of the most beloved and recognisable styles in British housing, with millions of properties from this period still standing across the UK today.
At the heart of this architectural heritage are the beautiful windows that define the Victorian era – from elegant sliding sash designs to ornate bay windows that flood interior space with natural light.
Whether you’re a proud owner of a Victorian property looking to restore original features, or you’re seeking replacements that honour charm whilst meeting modern performance standards, understanding the key features of Victorian windows is essential.
This guide explores:
- The features that define Victorian windows
- Popular Victorian window styles
- Finding the perfect replacement Victorian windows for any property

What defines Victorian windows?
The Victorian era (1837-1901) saw dramatic changes in window design and manufacturing. Thanks to the repeal of the Glass Tax in 1845 and advances in glass production, homeowners could finally afford larger glass panes and more elaborate window styles.
Victorian windows are characterised by several distinctive features.
Vertical proportions: Victorian windows are typically taller than they are wide, creating the elegant vertical lines that define Victorian homes.
Sash windows: The sliding sash window became the dominant style, particularly in terraced houses and townhouses.
Larger panes: Early Victorian windows featured smaller panes divided by glazing bars, but with technological advancements, larger glass panes became available and increasingly fashionable.
Decorative elements: Ornate details including stained glass, etched patterns, and coloured glass panels were popular, especially in front door surrounds and upper sash sections.
Bay windows: These projecting windows became a key feature of Victorian architecture, offering panoramic views and additional natural light.
Popular Victorian window styles
Sliding sash windows
Timber sash windows are perhaps the most iconic element of Victorian architecture. These beautiful windows feature two movable sashes that slide vertically, with the lower sash typically opening for ventilation.
At Bereco, our wooden sash windows can replicate these authentic period designs whilst incorporating modern materials and performance standards. We offer both spiral balance and traditional cords and weights mechanisms to suit your preferences.
Bay and bow windows
Bay windows became hugely popular during the Victorian era, particularly in Queen Anne style properties. These projecting windows (made up of a combination of sliding sash windows, casement windows and fixed picture windows) maximise natural light – a highly desirable feature in often-narrow Victorian terraced homes.
Victorian bay windows typically feature:
- Three or more window panels set at angles
- Decorative brackets and corbels beneath
- Intricate details in the window frames
- Often incorporating sash windows within the bay structure
Bow windows, which curve gently outwards, were another Victorian favourite, offering even more elegant panoramic views.

Lipped casement windows and flush casement windows
Whilst sliding sash windows dominated, casement windows were also used in Victorian homes, particularly in Gothic Revival style properties, and later Victorian buildings influenced by the Arts and Crafts movement.
Victorian casement windows often featured side-hung opening sashes with decorative ironmongery and sometimes intricate leaded designs.
While flush casement windows (where the opening sash sits completely flush with the outer frame when closed) are the most historically accurate casement windows for this period, at Bereco we also offer lipped casement windows. These are a more recent invention (dating back to around the 1950s) but offer a similar style, especially when finished with moulding profiles, glazing bars and heritage-inspired ironmongery.
Distinctive Victorian window features: customisation options
Glazing patterns and stained glass
The Victorians loved ornate details, and their windows reflected this passion for decoration.
Key features include:
- Stained glass: Coloured and patterned glass panels, particularly in hallways and upper sash sections
- Etched glass: Frosted or acid-etched glass offering privacy whilst allowing light
- Margin lights: Coloured glass borders around clear central panes
- Grille patterns: Decorative glazing bar arrangements creating geometric designs
Ironmongery and hardware
The Victorians paid meticulous attention to even the smallest details, and window ironmongery was no exception. The right hardware not only ensures smooth operation but also contributes significantly to authentic period character.
Key ironmongery choices include:
- Lifts and handles: Period-appropriate hook lifts for the lower sash, ring lifts for cords and weights windows
- Finish options: Select from antique brass, polished brass, black, chrome, or other finishes from our range of 10 metal accents to match your property’s character
- Opening restrictors: Discreet safety features available in designs that complement Victorian aesthetics

Upgrading Victorian windows: When replacement is necessary
If you’re fortunate enough to have original Victorian windows in good condition, proper maintenance can extend their lifespan significantly.
However, despite best efforts, sometimes original Victorian windows reach the end of their serviceable life. Rot, poor thermal performance, excessive draughts, or irreparable damage may necessitate replacement.
When replacing Victorian windows, choosing the right windows that respect the period properties’ character is crucial.
Our timber sash windows and casement windows offer authentic replication of Victorian style windows with all the benefits of modern manufacturing.
Choose from our customisation options to perfectly match your existing windows:
- Traditional appearance with slim frames and appropriate proportions
- Traditional or heritage moulding profiles for an elegant, classic look
- Custom paint and stain finishes to match existing windows
- Option for stained glass and decorative elements
Improving energy efficiency
One common concern with Victorian windows is energy efficiency. Original single-glazed Victorian sash windows can be significant sources of heat loss.
However, you don’t need to compromise historical charm for better performance. Modern replacements can dramatically improve energy efficiency whilst maintaining authentic appearance:
- Double glazing: Our SlimLine glazing achieves excellent U-values whilst maintaining the slim profiles characteristic of Victorian windows
- Weather seals: Modern draught-proofing systems dramatically reduce air leakage
- Quality timber: Properly manufactured and finished timber sash windows provide superior insulation
- Traditional appearance: Our windows replicate original designs so closely that they’re indistinguishable from authentic Victorian windows
Our timber sash windows exceed current Part L building regulations, achieving impressive U-values that ensure your Victorian property is warm, comfortable, and cost-effective to heat.
Do I need planning permission to replace Victorian windows?
If your Victorian property is listed or located in a conservation area, you’ll need permission before replacing windows. This is to ensure that any replacements are in keeping with the character of the building. Our experienced team understands these requirements and can help you navigate the process.
