Customer Reviews
Our Kitchen is now filled with natural light all day
The flat skylights have completely transformed our kitchen extension. It’s now filled with natural light all day, and the room feels much larger and more inviting. The installation was neat, quick, and the team left no mess behind. Best decision we made for our Stockwell home.

The skylights have transformed our kitchen
Getting rid of those old yellow PVC panels was the best decision we made. The skylights have transformed our kitchen from dark and depressing to bright and airy. The installation team was tidy and professional throughout.

The performance of the new windows is in a different league
The black Schüco sash windows have completely transformed our Barnet home. They look stunning against the brickwork and retain the traditional sash character, but the performance is in a different league. The house is warmer, quieter, and the quality is outstanding. The installation team was respectful of our period property and left everything spotless. Highly recommended.

Frequently asked questions
The main differences lie in wall construction, roof design, glazing proportions and overall architectural appearance. Conservatories typically have predominantly glazed walls and roofs, while orangeries usually combine solid wall sections with large windows and a roof lantern.
Neither is universally better. The right choice depends on your property, intended use, budget and preferred design. An orangery may suit a kitchen-diner extension, while a conservatory may be ideal for a garden room or relaxation space.
Thermal comfort depends on the whole building design, insulation, glazing, ventilation, orientation and heating rather than the name of the extension alone. Both conservatories and orangeries can be comfortable year-round when properly specified.
A conservatory may have a lower starting cost in some cases, but specification, size, structural work and finishes can change the comparison. A high-specification conservatory can cost more than a simple orangery.
With suitable glazing, roof specification, ventilation, shading and heating, a conservatory can be used for much of the year. Modern glass roofs and solar-control glazing improve year-round usability.
Roof lanterns are a characteristic feature of many orangeries, but designs vary. The final configuration depends on the architectural approach and the homeowner’s preferences.
Yes, aluminium is a suitable option for many designs, subject to the selected system and project requirements. Aluminium offers slim sightlines and a contemporary appearance.
Yes. Modern uPVC systems offer design flexibility, low maintenance and appropriate thermal performance. uPVC is available in a range of colours and finishes beyond basic white.
Yes. We stand by the quality of our workmanship and materials. All our conservatories come with a comprehensive manufacturer’s and installation guarantee, giving you long-term protection and peace of mind. Specific warranty details will be provided with your quotation.
Yes. To meet building regulations and ensure adequate background ventilation, we can integrate almost invisible trickle vents into the window head.
Absolutely. While “Brilliant White” remains a classic choice, we offer a wide range ofRAL colours and woodgrain foils. Our most popular contemporary options include Anthracite Grey and Black, while our wood-effect finishes (like Irish Oak) provide the look of real timber without the maintenance.
Installation time varies depending on the door type, property construction, and any necessary adjustments. A straightforward replacement can often be completed within a day, while more complex installations may take longer. A professional installer can provide a more accurate timeframe after assessment.
A single handle controls both functions. The first turn opens the window in the tilt position. The second turn allows the window to swing open inwards.
Neither is universally better. Bi-fold doors are ideal if you want the widest possible physical opening and flexible ventilation. Sliding doors are ideal if you prioritise uninterrupted views, large glass panels, and a minimalist aesthetic. The right choice depends on your priorities and your property.
Yes. Aluminium door systems are typically made to measure to suit the specific opening and design requirements of each property.
Yes. Schüco profiles are engineered to span wide openings up to several metres in width, with individual panels capable of reaching heights of 3 metres or more. The robust aluminium frames and heavy‑duty running gear handle the extra weight of large panes of glass without distorting.
Yes. All of our window installations are backed by a comprehensive, insurance-backed guarantee, giving you complete confidence and peace of mind in your investment. We stand by the quality of our manufacturing and the expertise of our installation.
Yes, they are highly energy-efficient. With modern frames and advanced double or triple glazing, they can significantly reduce heat loss from your home.
Yes. Modern uPVC systems offer design flexibility, low maintenance and appropriate thermal performance. uPVC is available in a range of colours and finishes beyond basic white.
Maintenance is minimal. Wipe down frames with a mild soapy solution, lubricate hinges and tracks annually with a silicone‑based spray, and check that drainage channels are clear. The factory‑applied powder coating does not need repainting.
Yes. Eurocell uPVC is a fully recyclable material, and the exceptional energy efficiency of the windows helps to reduce your carbon footprint by lowering heating costs.
Absolutely. This is one of the key benefits of an orangery. Its solid structure and integrated feel make it perfect for use as a kitchen, dining room, main lounge, or even a home office.
They eliminate several common vulnerabilities. Without a visible key cylinder, lock snapping, bumping, and picking are no longer threats. Electronic access logs and encryption add layers of security that a purely mechanical lock cannot provide.
Absolutely. We specialise in creating windows that complement your home’s architecture, from traditional sash windows for period properties to sleek, modern designs for contemporary builds.
Schüco Bi-Fold doors offer balance with style security, elegance and durability. Schüco smooth-running, stainless steel roller system allows you to move vents up to 3m in height and 100kg in weight effortlessly.
Absolutely. While known for modern designs, aluminium doors are incredibly versatile. We offer a range of classic colours (like heritage greens and greys) and even wood-effect finishes. The slim sightlines can be designed to complement traditional architecture, offering improved performance without compromising character.
Absolutely. With slim profiles, a vast range of colours (including anthracite grey, black, and Chartwell Green), and authentic woodgrain finishes, modern uPVC windows are at the forefront of contemporary home design. They are featured in new builds, renovations, and even conservation areas across the UK.
Modern aluminium windows are highly energy-efficient. They incorporate thermal breaks—insulating sections within the frame—which, combined with high-performance glazing, provide excellent thermal performance.
