At CRW Contracting Ltd we provide reliable and professional commercial plumbing services for businesses, construction projects and refurbishment schemes across the UK. We undertake full first and second fix plumbing installations, working to industry standards and delivering systems that are safe, efficient and built to last.
What Are Commercial Plumbing Services?
Commercial plumbing involves the installation and maintenance of systems that supply water, remove waste and support heating or cooling throughout a building. Unlike domestic plumbing, commercial systems must handle greater demand, higher usage and strict compliance requirements, making proper installation essential.
First fix plumbing covers all pipework, supply lines, drainage routes and concealed components that sit behind walls, floors or ceilings. Second fix plumbing includes all visible fixtures, fittings, sanitaryware and final connections that complete the system and make it fully operational.
This structured process ensures commercial buildings receive a dependable plumbing system that meets both regulatory and user demands.
Our Process
Every project begins with a detailed assessment of the building layout, water requirements and construction schedule. We coordinate closely with other trades to ensure all pipework routes, service zones and installation timings align with the overall project plan.
During the first fix stage we install all primary pipework, hot and cold services, waste lines, isolating valves, plant room connections and any necessary ventilation components. Everything is positioned accurately and pressure tested before walls and floors are closed.
The second fix stage involves installing sinks, basins, toilets, urinals, taps, traps, commercial fixtures and all required fittings. All components are connected, tested and commissioned to ensure the system operates safely and efficiently.
We complete every installation with full checks for leaks, flow rates and performance so the system is ready for immediate use.
Precision and Compliance
Commercial plumbing must comply with water regulations, building standards and hygiene requirements. Our team follows the correct installation methods, uses approved materials and ensures all work meets the relevant UK standards.
We also ensure pipework is correctly insulated, safely routed and positioned for accessibility and long-term maintenance. Every stage is handled with accuracy to guarantee a reliable and compliant system.
