Different types of windows and costs
Getting to know the different types of windows is important, as your choice can have a big impact on installation costs.
Compare your different window options:
| Window Type | Average Installation Cost |
|---|---|
| uPVC | £500 – £1,200 |
| Timber | £900 – £1,500 |
| Aluminium | £800 – £1,400 |
Different window styles also have different benefits:
-
For instance, uPVC windows are generally more affordable due to their ease of installation and low maintenance.
-
Timber windows, while providing a traditional look, often come with higher installation costs due to their material and craftsmanship requirements.
-
Aluminium windows strike a balance, offering sleek design and durability, which makes them a mid-range option.

FAQ: Common questions about window fitting costs
How does the cost of fitting a window differ between new construction and replacement windows?
The cost of fitting a window can vary significantly between new construction and replacement windows due to different installation requirements. New construction windows are generally installed in new buildings or extensions and are fitted into predefined openings, which may involve additional structural work and customisation. This can increase labour and material costs.
What benefits might justify a higher window installation cost for energy-efficient windows?
Energy-efficient windows can be more costly to install initially, but they offer several long-term benefits that may justify the higher expense. These windows often come with features like low-emissivity (Low-E) glass, double or triple glazing, and tightly sealed frames, which can reduce energy bills by improving insulation and minimising heat loss. This makes homes more comfortable and may lead to a significant reduction in heating and cooling costs over time.
How long does a typical window installation take?
The duration of a window installation depends on the number and type of windows being fitted, as well as the property’s condition. On average, a single standard window can be installed in around one to two hours, while a full-house replacement may take one to two days. Complex designs, such as bay or custom-shaped windows, can extend the timeframe slightly due to the additional work involved.
Do window fitting costs include removing old windows?
In most cases, window fitting quotes include the removal and disposal of old windows, but it’s always best to confirm this with your installer before work begins. Some companies may charge an additional fee, especially if old frames need extra work to remove safely or if specialised disposal is required.

Bifold door leak
Anonymous user 05/06/2026 - 8.00 AM
Hi wanted some advice please I have some origin bi fold doors (3yrs old) Which have been supplied and installed by a company. In dec we noticed water pooling on tile on the left and damaged skirting. We’ve ripped off skirting board recently due to heavy rain and some plasterboard which was damp and inside when you put water in track it drains through holes of cill but still leaking in the corner inside too.This door is used for opening for access to garden Haven’t noticed anything on the opposite end of the bifold (that we can see) I’ve asked glazer and he put a bit of silicone at end of track but hasn’t made any difference Clearly it’s rain water hitting door and then leaks into track and trickles out onto brickwork inside .From what I can see there is foam there on inside and siliconed well outside. Please can someone help.. fed Up of being fobbed off as there’s been few issues with random windows around house. Is there a fix without removing the door?thanks

Lintels
Anonymous user 05/06/2026 - 7.59 AM
If windows are replaced/to be replaced- If lintels are required, would the window fitter do this or would I need to source another trades person for this? We need new windows for our home and likely need lintels but before I ring around/shop for quotes - wanted to check with so I was prepared. Am aware there will be additional cost for lintels if required on top of the windows and installation
