About Windowparts Ltd.

Welcome to the Windowparts Ltd online shop. We specialise in the supply of window and door handles, locks, glass units and window units, plus tools, fittings and any other accessories that the door and window industry needs. With over 25 years experience we have gained a reputation for excellent customer service and very reasonable prices.

Windowparts are now firmly established as one of the UK's top suppliers of hardware, locks, tools and ancillaries for the double glazing spares, repairs and maintenance market.


By keeping a vast range of general repair products we have been able to stay ahead of our competitors. With the introduction and continued development of the Flexi range, Windowparts is providing a range of easy to fit solutions for numerous applications. This allows for the repair and maintenance companies to carry a range of repair products suitable for multiple applications, thereby cutting down on the stock items carried by each vehicle.

As the repair business has developed, we find that we are now dealing with an increasing number of locksmiths. Market research tells us that up to 80% of all calls are uPVC related.

This website holds a limited selection of our products at the moment. If you need an item related to our business it's very likely that we will have the part you need in one of our warehouses. Give us a call or email us and we will do our best to help you out.

Sometimes our website has lower prices than offered in store, this is due to the decreased costs of trading online. If you would like to take advantage of these prices then please use our website.

Windowparts Shops.

Windowparts currently operates from two locations. Our original 10,000sq/ft warehouse in Luton has gone from strength to strength and continues to offer quality parts at great prices to both trade and retail consumers.

The Windowparts branch at Staples Corner in North London was the first time we opened outside of our main premises in Luton and marked the first stage of an ambitious expansion plan.

The 3,500 square foot unit is on a busy trading estate and was carefully selected for its prime location covering North London. Its close proximity to the North circular road and the A1 and M1 motorway make it ideal for anybody needing window parts.

Although we add new items regularly to this site, our warehouses hold much more stock than we show on-line. If you have a query about an item you cannot see on our site, then please call or email and we will do our best to help you find the items you need.
