Old window disposal and recycling

Once your shiny new windows are in, what happens to the old ones? More of them get recycled than most people realise. Here is how uPVC, timber and glass are handled after a replacement, who is responsible for taking them away, and how to dispose of frames responsibly if you ever need to.

Who takes the old windows away?

In almost every case, your installer removes and disposes of the old windows as part of the job — it should be included in the price you agree at your window survey. Old frames, glass and offcuts leave with the crew at the end, rather than being left in your garden. It is always worth confirming this is included when you compare quotes; a tidy clear-up is one of the things people most often praise in our customer reviews.

Can old windows really be recycled?

Yes — and increasingly they are. The three main materials each have an established route:

• uPVC: old frames are separated from the glass and metal, then granulated and reprocessed into new products such as window profiles, pipes and decking. uPVC can be recycled several times over.
• Glass: sealed units are broken down so the glass can be recovered. Because it is treated and coated, it usually goes into products like aggregate and insulation rather than back into new windows.
• Timber: sound wood can be repurposed or chipped for board and biomass, while the metal fittings are recovered as scrap.

How responsible disposal works

Reputable installers send removed windows to licensed waste and recycling partners rather than to landfill. Many are signed up to material take-back schemes that keep uPVC in circulation. If you would rather keep a couple of old frames — for a greenhouse, cold frame or workshop project — just say so before the day and the crew can leave them for you. Choosing a firm you have taken care vetting your installer first makes it easy to check their disposal is above board.

Disposing of windows yourself

If you are removing windows outside of a full installation — say, during a renovation — you cannot put frames or glass in your household bin. Your options are:

• Take them to a local household waste recycling centre, checking first whether uPVC and glass go in separate streams.
• Book a licensed waste carrier, and keep the transfer note as proof of responsible disposal.
• Offer sound frames on a local reuse or freecycle group — someone may want them for a project.

Recycling old windows is a small but real win: it keeps material out of landfill just as the new units start cutting your heat loss and tackling the everyday problems new windows solve.
