Customer Reviews
Now it is bright, warm, and a joy to spend time in
The lean-to glass roof has completely transformed our kitchen extension. It’s now bright, warm, and a joy to spend time in, even on gloomy London days. The team removed the old polycarbonate roof with no fuss and installed the new glass roof beautifully. Highly recommended.

Frequently asked questions
Check for verifiable credentials, a physical business address, a documented trading history, and consistent independent reviews. Ask for a detailed written quotation, confirm whether installation is carried out by the company’s own teams, and ensure you understand the guarantees and aftercare arrangements before signing. A reputable installer will welcome these questions and answer them clearly.
FENSA registration is one established way to demonstrate that replacement glazing complies with Building Regulations in England and Wales, and it provides a certificate confirming local council registration. It is not the only route — other competent person schemes and building control inspections also exist — but you should always verify any claimed registration directly on the relevant scheme’s register rather than relying on a logo alone.
Qualifications vary by role and scheme. Look for evidence that installation teams are trained and competent, that the company is registered with a recognised competent person scheme where applicable, and that it works with established systems manufacturers whose products carry documented performance information. Ask how installation quality is supervised and whether the fitters are employed directly or subcontracted.
A proper quotation should specify the number and type of windows and doors, materials, frame profiles and system manufacturers, glazing specifications, colours and finishes, hardware and locking systems, removal and disposal of existing units, installation and finishing work, timescales, payment arrangements, and guarantees. Vague wording such as “supply and fit” should be replaced with detail.
A proper quotation should specify the number and type of windows and doors, materials, frame profiles and system manufacturers, glazing specifications, colours and finishes, hardware and locking systems, removal and disposal of existing units, installation and finishing work, timescales, payment arrangements, and guarantees. Vague wording such as “supply and fit” should be replaced with detail.
The lifespan depends on the material, system quality, exposure conditions, and maintenance. Well-manufactured uPVC and aluminium systems installed correctly can remain functional for many years, but no responsible company should promise a specific lifespan without reference to the product’s documented performance and the conditions in which it is installed. Regular cleaning, adjustment, and prompt attention to minor issues help extend service life.
You should expect clarity on the separate guarantees covering the product, the glazing units, the hardware, and the installation workmanship. Check the duration, coverage, exclusions, and claims procedure for each, and ask whether any guarantee is insurance-backed. A reputable installer will explain these arrangements before the contract is signed, not afterwards.
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.
A high-quality aluminium door system, like those from Schüco, can last 40-45 years or more with minimal care. The aluminium itself does not degrade, and the powder-coated finishes are designed to withstand decades of UK weather without fading, peeling, or corroding.
Each material has its strengths. Composite doors offer a good balance of security, thermal performance, and traditional aesthetics. Aluminium doors provide slim sightlines and a contemporary look. uPVC doors are practical, low-maintenance, and cost-effective. The best choice depends on your priorities and property style.
Triple glazing offers superior thermal and acoustic performance compared with double glazing. It’s worth considering for noisy locations, homes aiming for maximum energy efficiency, or properties with large glazed areas. However, it isn’t necessary for every property — a well-specified double-glazed window is more than adequate for many homes.
Absolutely. Composite doors are available in a huge range of colours, finishes, glazing options and hardware styles. Whether you prefer traditional or contemporary, there’s a door to match your taste.
High-quality uPVC windows have a life expectancy of 30-35 years or more. They are incredibly durable and are backed by extensive guarantees, which we are proud to offer on our products and installation.
The cost varies depending on the size, style, colour, glazing, and hardware options you choose. Because we manufacture them ourselves, we offer highly competitive pricing. Contact us for a free, detailed, and no-obligation quote tailored to your specific needs.
Yes. Modern woodgrain-effect uPVC uses advanced foiling techniques to create an authentic timber texture and appearance. Finishes like English Oak, Golden Oak, and Irish Oak are virtually indistinguishable from real wood.
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.
Bi-fold doors are made of panels connected by hinges that fold and stack to the side. Sliding doors have large panels that slide horizontally behind or alongside one another. Bi-fold doors create a wider clear opening; sliding doors typically retain more glass in place.
Absolutely. Schüco offers an extensive palette of over 200 colours and finishes. You can choose from standard RAL colours, metallic effects, anodized finishes, or even realistic timber-effect foils. You can even specify different colours for the inside and outside of the door to match your interior décor and exterior facade perfectly.
Check for verifiable credentials, a physical business address, a documented trading history, and consistent independent reviews. Ask for a detailed written quotation, confirm whether installation is carried out by the company’s own teams, and ensure you understand the guarantees and aftercare arrangements before signing. A reputable installer will welcome these questions and answer them clearly.
Yes. New windows improve kerb appeal, energy efficiency, and security — all factors that can enhance a property’s market value. FENSA certification also provides documentation that buyers often look for.
Generally, yes. Three panes and two insulating cavities usually reduce heat loss more than two panes and one cavity. However, the actual difference depends on the complete window system – frame, glazing specification, spacers, seals and installation – not just the number of panes.
Yes. The solid, rigid construction of a composite door resists flexing and forced entry far better than uPVC. Combined with multi-point locking systems, they offer significantly enhanced security.
Modern, high-quality double or triple glazing provides excellent acoustic insulation. While you may hear a gentle sound during a heavy downpour (as you would with any window), it is a world away from the loud drumming associated with old polycarbonate roofs.
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.
All systems come with a highly secure locking mechanism, and we can install up to 8 panes of glass in our bi-fold doors.
You can choose from over 200 RAL colours in a matt, satin or gloss powder‑coat finish. Anodised metallic effects, textured finishes and dual‑colour options (different colours inside and out) are also available. We can match most architectural colour schemes.
In most cases, no. Installing a roof lantern on an existing flat roof typically falls under “Permitted Development” rights. If it’s part of a new extension, it’s usually covered by the (often-permitted) extension plans. We can provide advice on this during our survey, but we always recommend checking with your local authority.
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.
