How much is a uPVC sliding sash window?

The total cost of installing a new uPVC sliding sash window is around £520 – £800 and will vary based on several factors.

How much more expensive are uPVC sash windows?

Generally, uPVC sash windows aren’t as expensive as their wooden frame counterparts, particularly if the timber is hardwood.

Prices for uPVC sash windows start as low as £520. While this figure isn’t the cheapest option compared to speedy draught-proofing, it’s undoubtedly less expensive than timber frame replacements which can easily set you back £925. 

Are uPVC sliding sash windows any good?

From enhancing your property’s value to cutting down your yearly heating bills, installing uPVC sliding sash windows is more than worth the job if you have sufficient funds.

Not only this, modern uPVC sash windows require little maintenance. While timber needs repainting and revarnishing to keep them in tip-top condition, uPVC sash windows need little to no maintenance.

Can you buy uPVC sash windows?

Yes, you can purchase uPVC sash windows from several window manufacturers, either on the high street or online. That said, your local window installer may also be able to purchase your uPVC sash window on your behalf for a better price than if you were to buy one yourself.
