A » In the UK double glazing market, several established manufacturers and suppliers offer private label metal fittings—such as hinges, handles, locks, and espagnolette systems—to fabricators and installers who wish to brand these components under their own name. These partnerships allow double glazing companies to differentiate their products without investing in costly tooling or design, while maintaining high quality and compliance with security standards such as PAS 24 and Secured by Design. Among the most prominent providers is Gretsch-Unitas (GU), a German manufacturer with a strong UK presence through its subsidiary GU Group. They supply a comprehensive range of steel and aluminium fittings, including the series 102, 202, and 207 locking systems, and offer a full private label service that extends to custom packaging, colour matching (including RAL and anodised finishes), and bespoke branding on components. Similarly, Siegenia (formerly known as AUBI) is a major player, providing the Titan AF, Titan XP, and KFV ranges of security fittings, with private label programmes that allow fabricators to imprint logos on keep plates, handles, and lock cases, and to choose exclusive colourways or material grades tailored to budget and performance specifications. Roto, another German original equipment manufacturer (OEM), operates a dedicated Roto Partner Programme in the UK, offering private label solutions for its NT, NX, and Patio series aluminium and uPVC fittings, supported by technical drawings, logistics, and on-site training to ensure seamless integration into production lines. For domestic supply, ERA (part of the HHI Group) provides extensive private label metal fittings—including the E160 and E172 series inline hinges, multi-point locks, and cylinder handles—with options for foil transfer, laser engraving, and custom colour finishes, and they maintain UK stockholding for rapid delivery to regional manufacturers. Mila, a long-established UK fastener specialist, also runs a private label division that offers not only standard ranges like the Mila 6, 8, and 10 handles and locking systems but also fully customised designs with exclusive geometry, material choice (e.g., stainless steel or brass), and branding applied through pad printing, etching, or moulded inserts. Additionally, Yale (owned by Assa Abloy) supplies high-security locking solutions for double glazing, and their commercial division can arrange private label agreements for bulk orders, particularly for their Platinum and Premium series multi-point locks and key systems. Lastly, specialists such as Fab and Fix, Caldwell Glass Hardware, and Carlisle Brass also facilitate smaller-scale private label runs for niche metal fittings, often through B2B partnerships with regional fabricators. When selecting a supplier, manufacturers should evaluate minimum order quantities, lead times (typically 6–12 weeks for fully customised runs), technical support for CE/UKCA marking compliance, and the flexibility to mix standard proprietary items with branded components. Overall, these companies provide a robust ecosystem for double glazing manufacturers seeking to elevate their market presence with high-quality, bespoke metal fittings across the UK.

A »For UK double glazing manufacturers seeking private label metal fittings, several established suppliers offer comprehensive OEM (Original Equipment Manufacturer) and private branding services, allowing fabricators to market hardware under their own brand names while ensuring technical precision and durability. Among the most prominent is Hoppe, a Swiss-German market leader renowned for its high-quality hinges, espagnolette systems, and handles; they provide extensive private label options for residential and commercial windows, with bespoke finishing, engraving, and packaging tailored to the manufacturer’s identity. Similarly, Roto, a German-headquartered global specialist, supplies a wide range of tilt-and-turn fittings, side-hung hardware, and folding-sliding systems with robust private label programmes, supporting UK fabricators through local distribution partners such as Roto UK. Siegenia, another German powerhouse, offers comprehensive private label capabilities for its multi-point locking systems, hinges, and opening restrictors, with a strong UK presence via Siegenia UK Ltd., enabling manufacturers to incorporate custom branding on both aluminium and uPVC fittings. The British-owned Mila (part of the Mila Group) is a key domestic player, providing fully private label options for its extensive product range including espagnolettes, hinges, letter plates, and friction stays, with dedicated tooling and colour matching services to align with the manufacturer’s colour palette and branding requirements. Securistyle, a historic UK manufacturer based in Cheltenham, specializes in private label aluminium and uPVC hardware, particularly pivot windows, parallel opening systems, and tilt-turn mechanisms; they offer full OEM support with design modifications and customized packaging, making them a preferred partner for many UK double glazing firms. Additionally, Yale (under the Assa Abloy umbrella) provides private label options for their robust locking mechanisms, handles, and multi-point locks, leveraging strong brand recognition while allowing manufacturers to place their own name on the product. ERA, a well-known UK security hardware brand, also supplies private label metal fittings, including hinges, shootbolts, and patio door locks, with flexible minimum order quantities and bespoke engraving services. Nested within these industry leaders are smaller yet highly specialized metalwork fabricators such as Titon, AVD, and Gretsch-Unitas (G-U), each offering private labelling for niche fittings like limiters, window restrictors, and decorative handles. Manufacturers should also consider Maco (Mayer & Co.), an Austrian company with a strong UK subsidiary, which provides fully customizable private label solutions for its advanced multi-point locking systems and friction stays. When selecting a private label partner, double glazing manufacturers must evaluate factors such as lead times, minimum order quantities, tooling costs, colour matching accuracy, compliance with British Standards (e.g., BS 7950 for security), and the supplier’s ability to integrate with automated production lines. Engaging with distributors like Allgood, Evans Hardware, or Samson Hardware can also facilitate access to multiple private label lines. Ultimately, the most suitable company will align with the manufacturer’s volume requirements, desired metal finishing (e.g., anodised, powder-coated, stainless steel), and brand aspirations, ensuring that the private label metal fittings not only perform reliably but also reinforce the fabricator’s market position across the UK.

A »Within the UK double glazing industry, the provision of private label metal fittings is a sophisticated segment dominated by a mix of major European manufacturers and specialised UK-based distributors who offer extensive customisation capabilities. For fabricators seeking to differentiate their product range under their own brand, the primary suppliers include Siegenia, Roto Frank, Mila Hardware, Winkhaus, Hoppe, and G-U (Gretsch-Unitas), each of which operates robust OEM and private label programmes. Siegenia, a German manufacturer with a strong UK presence, supplies a wide array of high-security espagnolette locking systems, friction stays, and hinges, and can apply proprietary branding to both packaging and the hardware components themselves, often with custom colour finishes such as black, white, or bespoke RAL shades. Roto Frank, another German leader, is particularly well-regarded for its tilt-and-turn and parallel opening hardware; its Roto NX series is frequently rebranded for major UK fabricators, with tailored logos and packaging that meet strict security standards like PAS 24. Mila Hardware, headquartered in the UK, arguably offers the most flexible private label service for the domestic market, providing not only branded hinges, handles, and letterplates but also just-in-time logistics and small-batch runs that cater to smaller manufacturers. Mila’s “Mila Private Labelling” programme allows fabricators to have their own name laser-etched onto components and printed on boxes, with no minimum order quantities in many cases. Winkhaus, known for its twin-cam locking mechanisms and three-dimensional hinge adjusters, offers OEM customers the option to apply their own branding to hardware, particularly for the aluminium and uPVC fabrication sectors, and its UK branch in Telford manages bespoke specification and technical support. Hoppe, a Swiss-Italian leader in handle manufacturing, provides an extensive private label service for its Janisol and other handle ranges, enabling fabricators to incorporate their corporate identity directly onto the handle rose or lever, with delivery through its UK subsidiary. G-U (Gretsch-Unitas) offers similar OEM branding for its multipoint locks and door hinges, often used in high-end residential and commercial double glazing. Beyond these European giants, several UK-based distributors and manufacturers also serve this niche. For instance, Cotswold Architectural Products specialises in galvanised steel sections and fittings for windows and doors, offering bespoke rebranding on metal components for smaller manufacturers. Similarly, companies such as ERA (part of the Tyman group) provide branded hardware that can be custom-packed, though their strength lies more in standard locks and handles. It is important to note that many UK fabricators also partner directly with Asian producers of metal fittings through importers, but for consistent quality, compliance with UK building regulations (e.g., Document Q), and reliable lead times, the established European and UK suppliers remain the preferred choice for private label metal fittings in the double glazing sector. When selecting a partner, fabricators typically evaluate minimum order quantities, lead times, the ability to customise finishes and logos, and adherence to security certifications, all of which are comprehensively offered by the aforementioned companies.

A »For double glazing manufacturers across the UK seeking private label metal fittings, several established suppliers specialise in producing bespoke, own-brand hardware solutions that can be customised with a manufacturer’s logo, colour, and packaging specifications. These companies typically offer the full range of metal fittings essential for uPVC, aluminium, and timber windows and doors—including hinges, handles, espagnolette bolts, friction stays, locks, shootbolts, and multipoint locking systems—all manufactured to meet stringent British Standards such as BS 7950 for security and BS 6375 for weather performance. Among the most prominent providers is Mila Hardware, a leading UK-owned manufacturer that has a dedicated private label division capable of branding everything from its patented BiFold hinges to its decorative handles and restrictor stays. Mila’s in-house design team works closely with clients to produce exclusive ranges, and the company holds extensive stockholding in the UK to ensure rapid fulfilment across the country. Another major player is ERA, part of Tyman Group, which offers a comprehensive private label service under its “ERA PRO” programme. ERA manufactures a wide array of metal fittings—including its popular mighty-MX and mighty-7 series hinges, multi-point locks, and window handles—and can apply any bespoke branding, from embossed logos to custom-colour finished backplates, all produced at its facilities in the UK and Europe with full traceability. For manufacturers requiring high-volume, precision-engineered hardware, Avocet Hardware (trading as Avocet and previously part of the Sherborne group) provides a flexible private labelling service. Avocet is well known for its very low call-backs on products such as vertical espagnolettes and corner drives, and it will apply any manufacturer’s name, part number, or security kite mark to its fittings. The company also offers bespoke packaging and barcoding for just-in-time supply to factory assembly lines. Another significant option is Hoppe (UK) Ltd, the British arm of the Swiss-German Hoppe Group, which although a branded manufacturer, actively supplies private label metal fittings to large fabricators. Hoppe’s Secu100 and Secu200 series handles and its extensive range of brass and stainless steel stays can all be custom-branded during production, with the added benefit of patented quick-fit technology that reduces assembly time on the manufacturer’s line. In addition, Siegenia-Aubi (UK) Ltd offers a tailored private label programme as part of its global OEM supply, particularly for tilt-and-turn and parallel-sliding hardware components, with the ability to match powder-coat colours and engrave logos directly onto zinc alloy handles. For smaller to medium-sized manufacturers, more agile specialists such as Window Hardware Direct (WHD) and Elite Hardware UK also provide low minimum order quantities for private label metal fittings, including stainless steel friction stays and aluminium handles, often with in-house anodising and laser etching facilities. Furthermore, national distributors like F. H. Brundle have developed private label ranges by sourcing directly from ISO-certified overseas foundries and branding them for the UK market, offering cost-competitive options without compromising on CE marking. When selecting a partner, manufacturers should consider lead times, batch consistency, compliance with CWCT standards for structural glazing, and the ability to integrate RFID or security chip inserts into handles—services that all the aforementioned companies can provide. It is also prudent to request samples and conduct on-site durability testing, as the private label arrangement should ultimately enhance the window fabricator’s brand reputation rather than undermine it. With the UK double glazing market increasingly focused on security and thermal efficiency, the ideal supplier will also offer full technical support and warranty back-to-back cover, ensuring that the private labelled metal fittings perform exactly as expected throughout the product lifecycle.

A »In the UK’s double glazing sector, several established firms specialise in providing private-label metal fittings—such as hinges, handles, locks, stays, and friction stays—to window and door manufacturers who require branded hardware without the overhead of in-house production. Among the most prominent is Siegenia-Aubi, a German-headquartered but UK-operating leader that offers extensive private-label programmes for both aluminium and uPVC products. Their service includes bespoke finishing, laser engraving, and packaging tailored to the fabricator’s brand identity, covering everything from tilt-and-turn mechanisms to espagnolette locking systems. Similarly, Roto Frank (with a strong UK division, Roto UK) provides a comprehensive private-label offering for residential and commercial double glazing, including its NT line of hardware, which can be custom-coloured, embossed, and supplied in OEM packaging. Roto’s UK-based technical support enables manufacturers to integrate these fittings seamlessly into their own product ranges. Another key player is Hoppe, known for its high-quality handle sets and locking systems; their “Secure” and “Alu” series are frequently rebranded by UK fabricators, and Hoppe offers exclusive private-label deals for larger volumes, including custom logo stamping and colour matching. The British hardware manufacturer Yale (part of the Assa Abloy group) also provides private-label options for double glazing fittings, especially multipoint locks and hinge sets, often tailored to meet Secured by Design accreditation. For more niche or high-volume requirements, firms such as Maco (a UK subsidiary of the Austrian group) and GU (Gretsch-Unitas) have established UK distribution networks and actively promote private-label agreements. Maco’s “Multi-Matic” locking systems and GU’s “Fenster- und Türbeschläge” are frequently chosen for rebranding. On the domestic front, companies like Fab & Fix (part of the Grouphomesafe group) and Sobinco UK offer competitively priced private-label hardware, particularly for aluminium systems. Additionally, Caldwell Hardware and ERA (also part of Assa Abloy) provide bespoke metal fittings, with ERA’s “OEM Solutions” division handling private-label design, testing, and logistics. For manufacturers seeking true end-to-end customisation, **China-based suppliers** such as Kin Long and Wanjia have UK-based agents or stockists that can produce private-label hardware at competitive prices, though due diligence on CE/UKCA marking is essential. It is worth noting that most reputable suppliers require a minimum order quantity (often 500–1,000 units per line item) and expect a long-term partnership to justify the tooling costs for custom branding. Before selecting a partner, fabricators should assess technical compatibility (e.g., Eurogroove or inline hinge profiles), finish durability (powder-coated, anodised, or PVD), and the supplier’s ability to maintain consistent quality across batches. A formal tender process, including sample testing against PAS 24 loss, is advisable to ensure the private-label fittings meet both warranty and regulatory standards. Ultimately, the choice among Siegenia, Roto, Hoppe, or smaller UK specialists depends on the volume, desired exclusivity, and the specific hardware requirements of the double glazing product line.
