Do you need to replace your existing windows? Perhaps you’re looking to have new windows installed as part of renovation on your property? If you are interested in finding an affordable option that is also low maintenance, eco-friendly, and provides your home with lots of beautiful natural light, you have probably considered uPVC sash windows and their price.
uPVC sash windows are fast becoming a great alternative to more traditional casement windows, as they also offer fantastic insulation and are exceptionally durable.
When it comes to choosing the right windows for your property though, that aspect of affordability we noted above is likely the thing that concerns people from outset.
How affordable are they, though?
In the following post, we are going to consider how much sash windows cost while looking at:
- the cost of replacing them
- if they are more expensive
- if they add value
- if are worth it
How Much Does A Upvc Sash Window Cost?
One of the things that make uPVC sash windows so desirable is their look, ease of use and low maintenance. But how much do sash windows cost?
As an estimate, you should expect to pay around £300 to £950 for a single sash window with double glazing.
Much of the costs will depend on:
- Where you are located
- The company you choose to hire to install your sash windows
- The size of them
- Any customised features or components

How Much Does It Cost To Replace A Sash Window?
What if you have existing sash windows in place and are looking to replace them because they need updating or are not performing as well as they once did?
Just as if you were having completely new uPVC sash windows installed for the first time, many factors can contribute to the cost.
Sash window prices are affected by factors such as:
Materials used – uPVC is the cheapest
Window size – the bigger the windows are, the more materials are needed.
How complex the design is – similarly, the more complex your windows are, the more they will cost
Glazing type – while single glazing is the cheapest, it is not the most effective, so if you want double or even triple, the price will be affected by this decision
Labour costs – even if you are incredibly good at DIY, it is still not recommended that you carry it out yourself, therefore you will need to hire a professional.
This can cause a huge amount of difference in the price, as all companies and contractors will charge differently.

Are Sash Windows More Expensive?
It depends, but even if it is the case that sash windows are more expensive than other options you may be considering, you need to weigh up the pros and cons.
Sash windows have a sterling reputation for offering the following advantages:
- Reduced heating costs
- Improved energy efficiency
- Reduced air and noise pollution
- Increased security
- Increased insulation
While it may initially cost more to have sash windows installed, the long-term savings more than compensate for that upfront spend.
They are also a lot more versatile and resistant to deterioration and problems that casement windows made from wood suffer terribly from with time.
Do uPVC Sash Windows Add Value?
This is an interesting question because it depends on who you ask.
There are some contractors and industry experts that suggest uPVC sash windows do not add much value to a property, compared to wooden sash windows.
However, others claim that they do.
It may be that it will depend on the area you live in, the style of property you have and whether it is an old building or listed building or a new build.

Are uPVC Sash Windows Worth it?
This is one of those questions that comes down to what you want and need from windows.
The upfront investment on uPVC sash windows can be off-putting, especially if you are looking for larger windows with double glazing.
However, you need to weigh up the pros and cons and think about what you get as a benefit of having sash windows.
Such as:
- They are easier to use
- Allow a lot of natural light in (which may suit you if your home is currently duller than you would like)
- They are also incredibly easy to maintain and look after
We would wholeheartedly recommend if you are looking for a great balance between form and function and windows with great aesthetics that you invest in uPVC sash windows.
They are more expensive than their wooden counterparts, but as uPVC, especially newer uPVC, is weatherproof, rust-resistant and does not prang, deteriorate, or buckle in the same way as wood, it tends to last longer.
As many uPVC window frames nowadays can be styled and coloured in a variety of ways, with the option for woodgrain effects, you can still get all the look and appeal of traditional wooden windows without the high maintenance and issues related to them.
Are Sash Windows More Expensive than Casement Windows?
If you are torn between choosing casement windows for your property or sash windows, you will be keen to know whether one is more expansive than the other.
There are three key differences you need to think about when choosing, one is that sash window frames generally are thicker on the exterior.
They are designed this way to hide the counterweights and make them look more aesthetically appealing.
In terms of functionality, casement windows swing to open and close, whereas sash windows slide up and down.
The biggest difference is the price, though, because sash windows are almost always the more expensive option.
We would recommend though, that you don’t base your decision on the right windows for your property on the price alone and that you factor in everything we have discussed in the post above when deciding whether uPVC sash windows are best for your property or not.
