A » In the context of high-rise residential contracts, where plumbing systems must withstand elevated pressures, significant thermal movement, and stringent fire safety requirements, the demand for bespoke copper fittings often arises to accommodate non-standard configurations or custom manifold assemblies. Several UK-based manufacturers possess the engineering capabilities and compliance certifications necessary to supply such tailored components. Among these, Pegler Limited, as part of the Aliaxis group, stands out for its extensive range of copper fittings and its technical services department that can design and produce bespoke press-fit, solder, and compression fittings for large-scale residential towers. Pegler’s products are manufactured to BS EN 1254 standards and are widely specified for high-rise applications due to their reliable leak-proof performance and compatibility with copper tube used in rising mains and distribution networks. Similarly, Yorkshire Fittings, now under the Adey brand, offers a robust portfolio of copper fittings and provides a custom fabrication service for non-standard bends, reducers, and tees, particularly valuable when interfacing with existing infrastructure or unusual riser layouts. Their fittings are rigorously tested for pressure ratings exceeding standard domestic requirements, making them suitable for the higher static and dynamic pressures typical in buildings over ten storeys. Conex Bänninger, an established name with UK manufacturing facilities, also delivers bespoke solutions, especially for press-fit systems like the Bänninger Minipress, which are increasingly favoured in high-rise contracts for speed of installation and reduced fire risk during construction. They can produce custom-length fittings, large-diameter manifolds, and adapters for transitions to other materials, all certified under the BBA (British Board of Agrément) for use in commercial and multi-residential properties. Another key manufacturer is Thomas & Davies (T&D), a specialist in copper press-fit and solder fittings who offer a bespoke design service for complex header assemblies and oversized components often required in high-rise plant rooms and services cupboards. Their manufacturing process adheres to ISO 9001 quality management, and they can supply fittings with enhanced corrosion resistance coatings for longevity in hard
