The Cost of Double Glazing a 3 Bed House in Leicester
For a typical 3-bedroom semi-detached property in Leicester, the cost of replacing double glazing generally ranges between £4,500 and £9,500*.
For example:
- A property with 8 windows and 2 uPVC doors may cost between £7,500 and £10,500.
- Larger 3-bed homes in areas such as Clarendon Park, Evington or Knighton, with more windows, may range from £10,000 to £15,000+.
Properties with large Victorian bay windows or structural alterations will sit toward the higher end.
Final costs depend on several factors:
- Window size and style (bay windows, common in Leicester Victorian terraces, cost more)
- Frame material (uPVC, aluminium, timber)
- Glass quality (low-E, acoustic glazing for busy Leicester roads, etc.)
- Installation complexity
- Customisation options
Every Leicester property is different, which is why a professional home survey is essential for accurate pricing.

How Property Type in Leicester Affects Double Glazing Costs
Across Leicester and Leicestershire, we commonly install windows in:
- 1930s semi-detached homes
- Victorian terraces
- Modern new-build estates
- Period properties in conservation areas
Older Leicester homes may require:
- Sash-style replacements
- Structural adjustments
- Conservation-compliant designs
This can affect overall installation time and cost.
How the Window Style Affects the Average Cost of Double Glazing
Casement Windows
Casement windows are a type of window that opens outward on hinges, like a door. They are typically attached to the window frame by one or more hinges on the side and are operated using a handle. Casement windows are popular due to their ease of use and ability to provide good ventilation when fully open.
The cost of double glazing for a white uPVC casement window typically varies between £500 and £1,200, depending on factors such as size, glazing design, and the number of windows being replaced in the property.
Tilt & Turn Windows
Tilt and turn windows are a type of window that has two opening functions. The first function allows the window to tilt inwards from the top, providing ventilation while maintaining security.
The second function allows the window to swing inwards like a door. Tilt and turn windows are popular due to their versatility and practicality, making them a popular choice for modern homes and buildings.
On average, the cost of tilt and turn double glazing windows is 20–30% more than a casement window.
Sash Windows
Sash windows are a type of window that consists of one or more movable panels, or sashes, that slide vertically past each other within a frame.
They are typically made of wood and have a traditional, classic look that is commonly seen in older buildings. Many listed buildings are required to have sash windows.
The cost of a double glazed sash window is typically 40–60% more than a standard uPVC casement window, depending on material and finish.
Bay & Bow Windows
Bay and bow windows are types of windows that protrude out from the main wall of a building, creating a unique and distinctive look. Bay windows are typically made up of three or more windows that are angled and joined together to form a bay shape. Bow windows, on the other hand, are composed of four or more windows that are curved or angled to create a semi-circular shape.
Bay and bow windows are popular for their ability to add space and light to a room while enhancing the overall aesthetic of a building.
Typically, the cost of a double glazed bay or bow window can be 100–150% more than a standard casement window, depending on size and configuration.
Comparing the Cost of Window Frame Materials
UPVC Windows
uPVC windows have commonly been accepted as the lowest-cost option. In fact, they’re three times cheaper than wooden frames, and they lead the market in energy efficiency.
uPVC windows offer a range of benefits that make them a popular choice for homeowners and builders alike. They’re durable, energy efficient, and completely customisable.
Aluminium Windows
Aluminium windows are windows that are constructed with aluminium frames. They are a popular choice for commercial and residential buildings due to their durability, strength, and sleek appearance.
Although aluminium windows are more expensive than uPVC windows, they offer a longer lifespan and can be a cost-effective option in the long run due to their durability and low maintenance requirements.
Timber Windows
Timber windows are windows that are constructed with wooden frames. They are a popular choice for traditional and period-style homes due to their natural beauty and warmth.
Wooden windows are a more eco-friendly option than uPVC, but they are much more expensive too.
Why Prices Vary Between Installers
You may see companies advertising very low prices online.
Be aware that pricing varies depending on:
- Glass specification (low-E, acoustic, triple glazing)
- Security hardware
- FENSA or Assure certification
- Insurance-backed guarantees
- Quality of installation
A very low quote can sometimes mean:
- Lower-grade frames
- Minimal aftercare
- No long-term guarantees
Is Double Glazing Worth the Cost?
For most Leicester homeowners, yes. Upgrading your windows offers several long-term benefits:
Lower Energy Bills
With rising energy costs across the UK, modern A-rated double glazing helps retain heat during Leicester’s colder winter months and reduce overheating in summer.
Reduced Outside Noise
If you live near busy areas such as Narborough Road, London Road, or the city centre, acoustic glazing can significantly reduce outside noise.
Increased Property Value
Energy-efficient windows can improve EPC ratings and make your Leicester property more attractive to future buyers.
Better Home Security
Modern multi-point locking systems provide greater protection for Leicester homeowners.
How Long Can Double Glazing Last?
No one wants to spend a large amount of money on double glazing windows that are not durable. However, the great news is that as technology has advanced in the manufacturing and materials used, the lifespan of double glazed windows has significantly improved.
Today, houses built in the UK have better structural integrity, and the double glazed windows installed in them have enhanced thermal performance. With proper installation and maintenance, modern double glazing can last 25–30 years or more.
In Leicester’s climate, high-quality uPVC and aluminium frames are designed to withstand:
- Heavy rainfall
- Frost
- Seasonal temperature changes
Choosing an experienced local installer ensures maximum durability and performance.
