Aluminium windows are ideal for contemporary London homes, extensions and refurbishments where you want slim frames, large glass areas and a clean, modern look. They sit comfortably within wider glazing schemes across the property.
Aluminium windows offer slim sightlines, strong frames and stable performance, which works well for modern house window replacement projects. They suit large openings, shaped windows, fixed light windows and aluminium bay windows where generous glass and light are a priority.
Maintenance is straightforward: aluminium frames are factory finished, so in most homes they need just periodic cleaning. With modern thermal breaks and high‑performance glazing, aluminium windows double glazed or triple glazed can support energy efficiency and help manage double glazing window costs over the life of the property.
Aluminium also works well alongside other window materials in the same home. Homeowners often combine aluminium windows with timber sash windows, timber casement windows or bespoke timber windows on key elevations and use more contemporary styles on garden‑facing sides.
Aluminium is well suited to projects where the design calls for a modern feel and strong visual links between inside and outside. Typical uses include:
Large panes, slim frames and carefully placed fixed light windows can create wide views and bright interiors, often with roof lanterns above.
Bespoke aluminium windows, shaped windows and roof lanterns can be combined to create consistent modern lines across all elevations.
Slim aluminium casement windows, tilt and turn windows and top hung window layouts provide good ventilation, easy cleaning and a neat appearance in tighter spaces.
Timber sash windows or timber bay windows at the front can sit alongside aluminium windows sliding or aluminium tilt and turn windows at the rear, where larger glazed areas and different proportions are possible.
Extensions and open‑plan spaces
Large panes, slim frames and carefully placed fixed light windows can create wide views and bright interiors, often with roof lanterns above.
Contemporary new builds
Bespoke aluminium windows, shaped windows and roof lanterns can be combined to create consistent modern lines across all elevations.
Urban homes and flats
Slim aluminium casement windows, tilt and turn windows and top hung window layouts provide good ventilation, easy cleaning and a neat appearance in tighter spaces.
Mixed‑material projects
Timber sash windows or timber bay windows at the front can sit alongside aluminium windows sliding or aluminium tilt and turn windows at the rear, where larger glazed areas and different proportions are possible.
Many projects involve working with architects and glazing designers who specify systems such as Origin windows, Schüco windows, Reynaers windows, Rationel windows, and Velfac windows, so aluminium windows become part of a coordinated package.
Understanding the market
Aluminium has a steady upward trend in the UK Market. In this article, we are going to discuss the current trends of aluminium windows and aluminium doors and why they are the product of choice when it comes to extensions and renovations in London and the whole of the UK.
Aluminium can be fabricated into a wide range of window styles, from simple opening units to more complex shapes and arrangements. The aim is to match how each room is used and how each elevation looks from outside.
Common aluminium window styles include:
A practical choice for many rooms, with flexible opening sizes and directions.
Often used on upper floors and in flats, giving inward opening for cleaning and secure tilt positions for ventilation.
Large non‑opening panes used to frame views or bring in maximum light, sometimes combined with a sliding system or roof lanterns in the same space.
Designs that echo the proportions of sash windows or timber sash windows while using slim aluminium profiles.
Bespoke aluminium windows made as bays, angled corners, or shaped windows to follow rooflines and architectural details.
Aluminium windows are powder‑coated in a wide range of RAL colours. Many homeowners choose classic whites and greys; others prefer deeper tones that work well with London brickwork or cladding.
Dual‑colour options allow one shade on the outside and another on the inside, so interior schemes with bespoke wooden windows, bespoke timber windows, or other finishes can be matched more closely. Handles and hardware come in various finishes, and careful attention to seals and sightlines helps aluminium windows sit neatly beside other bespoke windows on the same elevation.
Current aluminium window systems use thermal breaks and modern glazing to support comfortable indoor temperatures and good acoustic performance. There is scope to choose glazing according to how each elevation is exposed to weather and noise.
The most common choice for London homes and a practical balance between comfort, energy efficiency and cost. It suits most typical openings, from casement windows to bay and sash styles, and meets current building regulations for new and replacement windows.
Recommended where extra insulation or noise reduction is important, such as near busy roads, rail lines or flight paths. Triple glazed units improve thermal performance, reduce outside noise and work well in larger bespoke windows, aluminium bay windows and rooms with significant glass areas.
Designed to reduce outside noise in homes located near busy roads, rail lines, flight paths or lively urban streets. Acoustic units use laminated glass and specially tuned interlayers to dampen sound, which helps rooms feel calmer and more comfortable without changing the look of the window. It can be specified in most aluminium window styles, including casement, tilt and turn, fixed light and bay windows.
Posted on Michael ScorerTrustindex verifies that the original source of the review is Google. This is a very special building company. I've worked in housing for 30 years and everything I experienced about Citi Homes is best in class. From first contact, communication was quick, clear and high quality. Quotes arrived quickly with high quality cad drawings. Once the detailed design was agreed, a delivery and installation date was agreed and then met. The operatives who fitted all eight windows in two days (bearing in mind the new windows were a completely different design to the ones removed) were polite, extremely conscientious about minimising any damage, very professional, clean and tidy. The result is a great product, perfectly and quickly installed. I have been recommending this company to friends and colleagues. If you need new high quality windows, at a highly competitive price, look no further. I would always recommend getting two or three estimates, but I honestly think that would be for reassurance rather than as a serious competitor to Citi Homes.Posted on thomas humphriesTrustindex verifies that the original source of the review is Google. Citi Homes supplied new Rationel windows for our loft conversion. Great service throughout - good support through the quotation / ordering process and excellent communication on delivery times etc once the order was placed.Posted on Justin EarreyTrustindex verifies that the original source of the review is Google. Citi replaced my damaged Velfac balcony door: Great communication from Linas who managed to source a replacement from the manufacturers, even though the door is no longer produced. The install team also did a great job delivering and troubleshooting on site to ensure the door was replaced and now fully usable. Highly recommend.Posted on Mary ThumTrustindex verifies that the original source of the review is Google. Citi supplied a very large (2 metres X 2 metres) window to replace one that had shattered. The job involved craning the new unit up to our fourth-floor terrace and fixing it in position. Citi found a very good crane company to do the lift and dealt with our local council to get the necessary license to close the street during the work. We found Linas, the Citi manager who ran our job, to be very professional and easy to work with.Posted on dermot hayesTrustindex verifies that the original source of the review is Google. I spent an enormous amount of time researching doors and windows. I wanted triple glazed, thin elegant frames, affordability and value for money. I searched the net and contacted very many companies; some looked very good indeed apart from the affordability and some were not worth bothering about. I contacted Velfac UK who I had heard were very good and they put me on to Citi Homes Windows who handle their products. We went to visit the Citi Homes showroom and they were fantastic. Over a cup of tea we discussed with them what we wanted and they showed me frames that exactly fitted the brief. They were able to give me an estimate on the spot, based on approximate sizes and followed up with a visit to discuss the project with my builder and to take accurate measurements. They confirmed the price and we placed the order just before Christmas 2025, taking delivery in the middle of March 2026, about eight weeks turnaround if you take out the Christmas period. The windows and doors are installed and I am delighted with them. They are substantial and elegant frames of excellent quality. The fitters were great and very charming; in fact all the people at City Homes are very charming and excellent communicators which really helps. I think the doors and windows are of excellent value and I got exactly what I wanted; triple glazed, thin elegant frames, affordability and value for money. The total price including fitting was under £8000.00. I would certainly highly recommend them. Dermot Hayes.Posted on Rosie GastonTrustindex verifies that the original source of the review is Google. Wonderful experience with the team from start to finish. They replaced 5 floor to ceiling window panels for us after damage caused by a fire. The installation and service was seamless. Great communication, constant updates on progress, and the guys were super efficient, hard working, respectful and tidy. They’ve done a fab job and we couldn’t be happier with both the process and the final product. Thank you!Posted on Philip WareTrustindex verifies that the original source of the review is Google. Excellent service from the Citi Homes Windows Team. Very helpful and competative with their prices. We would have no hesitation in using them again on any future projects.Posted on danny vaiaTrustindex verifies that the original source of the review is Google.

Many projects use more than one window material. Aluminium suits large openings, modern elevations and spaces where slim frames and strong lines are important. Timber windows, bespoke timber windows and timber sash windows are often preferred for period façades and traditional street‑facing elevations. Composite systems offer a timber look internally with a different outer surface.
On some homes, aluminium is the main material on garden‑facing sides with bespoke aluminium windows and roof lanterns, while the street elevation keeps timber sash windows or timber bay windows to stay in keeping with neighbouring properties. Other projects choose a full package that mixes aluminium, timber windows and composite systems according to how each façade is used and viewed.
Well‑specified aluminium windows with quality powder‑coated finishes are designed for long service lives. In practice they are often chosen for projects where stability, low maintenance and long‑term appearance matter. All our aluminium windows also come with a manufacturer's warranty, giving you added peace of mind on both the frames and the finish.
In many London areas, aluminium windows are used at the rear or on extensions, while the front keeps timber sash windows, sash box window designs or bespoke timber windows. Aluminium windows sash‑style can follow similar proportions, which helps the new work sit comfortably alongside existing architecture.
Most systems accept both aluminium windows double glazed and triple glazed window units. The choice depends on priorities such as warmth, noise reduction and budget. During the survey and design stage we discuss which specification suits each elevation.
Yes. Mixed schemes are common: for example aluminium casement windows on the rear elevation, timber bay windows at the front, and fixed light windows on side walls. Projects sometimes also include Velfac doors, Rationel door products or similar systems, and aluminium windows can be chosen to work well alongside these.
Costs vary with size, style, glazing, brand and any bespoke features. Large bespoke aluminium windows, aluminium bay window designs and complex shapes usually sit at a higher level than basic double glazing windows. After a survey we provide a clear breakdown of windows installation price for the proposed specification.
Yes. Many projects involve bespoke windows packages that bring together aluminium windows, timber windows, timber sash windows, shaped windows and roof lanterns. The aim is to make sure proportions, sightlines and glazing choices feel consistent across the whole home.
