Step 1: Professional Plumbing Layout Design

Before any installation begins, the foundation of effective plumbing is in the layout. At Citywide Plumbers, we start with a full blueprint of your new home and develop a comprehensive plumbing plan that considers:

Kitchen and bathroom locations
Utility areas (e.g., laundry, boiler rooms)
Heating system design
Water pressure zones
Efficient drainage routes
Gas appliance placement (boiler, hob, etc.)

We collaborate closely with your architect or contractor to make sure our plumbing scheme aligns with the build's structural plans. This prevents costly reworks and ensures flawless integration.

Step 2: Installing the Pipework

Once the plan is finalised, our certified engineers begin with the first fix plumbing—that’s the stage where pipes are installed before walls are plastered or floors laid. We use only WRAS-approved materials, installing:

Mains water supply pipes
Hot and cold distribution lines
Waste and soil stacks
Central heating pipework
Gas supply lines

Our team guarantees that all pipe runs are tested for leaks, safely secured, and neatly routed for long-term durability.

Step 3: Installing Fixtures & Fittings

After your walls and floors are complete, we return for second fix plumbing—the installation of visible elements such as:

Toilets, taps, and sinks
Showers and bathtubs
Radiators and towel rails
Boilers and hot water cylinders
Washing machine and dishwasher points

At this stage, we ensure everything is fully connected, tested, and working correctly. We take pride in precision and cleanliness—leaving your property ready for move-in without mess or stress.

Full Compliance with UK Building Regulations

Every installation by Citywide Plumbers is fully compliant with British Building Regulations, including:

Part G (Sanitation, Hot Water Safety & Water Efficiency)
Part H (Drainage and Waste Disposal)
Gas Safety (Installation & Use) Regulations 1998

Our engineers are Gas Safe registered, so you can trust us with every gas installation and appliance connection. We also issue completion documentation for regulatory compliance and peace of mind.
