Holden Plumbing Services Ltd provides off-site prefabrication and modular plumbing solutions to support large-scale new-build and high-density developments across London, Essex, and the wider UK.
Where project requirements allow, we prefabricate key plumbing components off-site to improve installation quality, reduce on-site labour, and de-risk critical programme milestones.
Off-site prefabrication involves assembling plumbing systems in a controlled environment before delivering them to site ready for installation. This approach improves consistency, reduces site congestion, and allows faster, more predictable installation on live projects.
Our prefabrication solutions are project-specific and tailored to suit design intent, logistics, and programme constraints.
We prefabricate HDPE soil and waste stacks, including upright welded sections prepared off-site and delivered to site ready for rapid installation. This reduces on-site welding time and improves joint quality and consistency.
HIU cupboards are fully assembled, tested, and prepared off-site before delivery. Units arrive ready for fixing, helping reduce installation time, improve quality control, and simplify coordination with other trades.
We fabricate modular pipework sections designed to integrate seamlessly with risers, corridor services, and plant rooms. These assemblies are installed quickly on site, improving accuracy and reducing disruption.
By shifting key elements of the installation off-site, our clients benefit from:
This approach is particularly effective on high-density residential and multi-unit developments.
All prefabricated components are produced to agreed drawings and specifications, ensuring accuracy and compliance before arriving on site. Our teams coordinate closely with project managers and site teams to ensure smooth integration during installation.
Prefabrication works are delivered under qualified supervision to maintain the same standards of quality and compliance as our on-site installations.
If you are planning a development and would like to explore off-site prefabrication solutions, we would be pleased to discuss options tailored to your project requirements.
