Can I replace existing timber windows in a conservation area with uPVC sash windows?

You can install our products in a conservation area. However, this works on a project by project basis as each area is different.

We can advise on enquiry as to the customisation options that would provide the greatest chance of approval. Our team are here to help!

Can I install your sash windows in new builds?

Yes, you can install our products into a new build home. Our windows and doors are tested to comply with new build regulations, including Approved Document Q (security).

It’s important to let us know if you’re ordering products for a new build, as the specification will need to be altered to ensure the products are compliant.

How do I get a price for your sash windows?

You can design and request a price for your new sash windows here on our website. If you require a full service including survey and installation, you can enquire and get a price via one of our stockists.
