Window fitting for Chelsea’s period and modern homes
Chelsea’s streets hold some of London’s finest architecture: Georgian and Victorian terraces, red-brick mansion blocks, stucco villas and mews houses, alongside striking contemporary refurbishments. Replacing windows in homes like these takes more than a catalogue. The proportions, glazing bars and sightlines have to look right from the street, while the windows themselves need to keep out draughts, damp and traffic noise.
Lux Glazing is a London window fitting company that surveys, supplies and installs made-to-measure windows and doors in uPVC, aluminium and steel. As window fitters working across Chelsea, Kensington and south-west London, we handle everything from a single sash replacement to whole-house glazing, commercial curtain walling and shopfronts.
Every project starts with a free survey. We measure each opening, talk through styles, colours and glazing, flag anything that needs planning or listed building consent, and give you a clear written quote with no pressure and no obligation.

Reviews
Rated 5.0 on Google by our customers
Chose Lux Glazing for a steel front door with fingerprint access and an internal steel door. The finish exceeded expectations, the price came in around £1,500 below two other quotes, and the uniformed fitting team treated the home with real care.
Windows and a door were fitted in a single day, and the team tidied up afterwards, even taking their shoes off on carpeted floors. Dylan listened closely, and he and project manager Jay came back at the end to check everything was right.
Already noticing a real drop in noise. Three fitters worked hard all day, stayed polite throughout, tidied up at the end and came back the next day to take the old windows away.

FAQs
Window fitting in Chelsea: your questions answered
Straight answers from our window fitters on costs, planning, timings and what to expect on the day.
Every quote is priced for the property, so there is no single figure. The main factors are the number and size of windows, the style (sash, casement, tilt and turn or bay), the frame material, the glazing specification, access to upper floors or mansion blocks, and whether the work must meet conservation-area or listed-building requirements. After a free survey we give you a clear written quote with no obligation.
Often not, but Chelsea needs more care than most areas. Like-for-like replacements on a house outside a conservation area usually don’t need permission. Much of Chelsea lies within conservation areas, many buildings are listed and some streets have Article 4 directions, any of which can mean you need planning permission or listed building consent from the Royal Borough of Kensington and Chelsea. Flats don’t have the same permitted development rights as houses. We flag this at the survey so nothing is ordered before the right consent is in place.
Yes. We fit heritage-style sliding sash windows that match the glazing-bar layout, proportions and sightlines of the originals, so the front of the building keeps its character while the new windows seal properly against draughts and noise. Our Kensington project did exactly this for a first-floor apartment in a traditional brick building.
Most installations are completed in one to three days, depending on how many windows are being replaced and how easy access is. Because everything is made to measure, production usually takes around six to eight weeks after you approve the specification, and we give you a realistic timeline with your quote.
Yes. Our projects include new sash windows for a first-floor period apartment in Kensington and full-height bifold doors with a glass balustrade in a third-floor London apartment. We plan access, parking and any building management requirements before the fitting day.
Our windows and doors come with a 10-year guarantee, alongside the manufacturers’ own warranties. We explain exactly what is covered, in writing, before you commit.
We work carefully and tidily to keep disruption to a minimum, and we clean up before we leave, something customers mention in their Google reviews. Your old windows are removed and taken away.
Yes. In England, replacement windows and doors must meet Building Regulations for energy efficiency, as well as for safety glazing, ventilation and means of escape where these apply. Compliance is certified either by an installer registered with a Competent Person Scheme or through local authority Building Control, and we confirm how your installation will be certified before work starts.
