uPVC Windows London, Get A Quote

London Window Company has been fitting uPVC windows for homeowners across London and the surrounding areas for years. Local people trust us to do the job properly, from the first call right through to the final clean-up on the day of installation.

Replacing your windows is a significant decision. You want to know the products are good quality, the fitters know what they are doing, and the whole thing will not cause you unnecessary disruption. That is exactly what we aim to deliver every time.

A Range of uPVC Windows to Suit Your Property

Every home in London is different. Victorian terraces, modern new-builds, period conversions and everything in between all have their own requirements. Our range of uPVC windows covers all the main styles, so you can get something that fits your home properly rather than settling for a product that does not quite work.

All our uPVC frames are made to measure. Nothing is pulled off a shelf and forced to fit. Your measurements are taken carefully before anything is ordered, and each window is manufactured specifically for your property. That attention to detail makes a real difference to how the finished job looks and how well the windows perform over time.

Our uPVC Window Range

• Casement Windows, the most popular choice for homes across London, practical and clean-looking
• Double Glazed Windows, fitted with argon-filled units for strong thermal performance
• Triple Glazed Windows, for homeowners who want even greater insulation and noise reduction
• Tilt and Turn Windows, easy to clean from inside and a good option for upper floors
• Sash Windows, designed to suit period properties and maintain a traditional appearance
• Bay Windows, fitted as full replacement units to refresh the front of your home
• Flush Sash Windows, for a more contemporary finish that still suits older-style properties

Energy Ratings, Materials and the Guarantee

Our standard uPVC windows are A-rated for energy efficiency. The double glazed units use argon gas between the panes, which reduces heat transfer and helps keep warmth inside your home during colder months. Over a full year, that can make a noticeable difference to your heating costs.

The uPVC frames themselves are built to last. They will not rot, warp, peel or need painting at any point. Occasional cleaning with soapy water is all they need to stay looking good. Every installation comes with a 10-year guarantee on both the frames and the sealed glass units, giving you solid cover long after the fitting team has left.

Security is also taken seriously. Multi-point locking systems are fitted as standard, and the glazing units are designed to resist forced entry. It is not something every company shouts about, but it matters to the people living in the property.

What Our London Customers Say

Most of our work comes through word of mouth. Homeowners in London recommend us to neighbours, friends and family because the job gets done cleanly, on time and without any last-minute surprises on the bill. Our fitters are fully qualified and fully insured, and they treat your home with the same care they would their own.

We keep things simple. You get a clear, honest quote before any work begins. There is no pressure, no hard sell, and no hidden extras once the job is done. Fitting is usually completed in a single day for most properties, though larger jobs or bigger window counts may take a little longer. We will always give you a realistic timescale upfront.
