Copper Pipe

Learn more about copper pipe

Selecting the right copper pipe gauge and temper is critical for meeting UK building and water regulations. Rigid straight lengths deliver neat, professional runs for exposed surface pipework and heating circuits. Soft-annealed coils bend easily around structural obstacles, reducing the need for excess elbow fittings in concealed spaces or underfloor heating setups. Copper remains the preferred material for professional installers due to its thermal efficiency, fire-resistance rating, and full recyclability. 

Typical uses

• Central heating systems: Routing hot water flow and return lines between boilers, radiators, and manifolds.

• Domestic water services: Supplying high-pressure mains water, hot water outlets, and cold storage connections.

• Gas supply lines: Installing secure, rigid gas pipework for domestic and commercial appliances.

• Underfloor heating & refrigeration: Utilising flexible coiled copper for continuous, joint-free underfloor heating loops.

How to choose the right copper pipe

• Copper pipe choice starts with the application and the run.

• Match the diameter to the flow you need, then choose the length that suits the layout and helps reduce wastage.

• Use 15mm pipe copper for smaller domestic connections, such as feeds to taps, radiators and appliances.

• Use 28mm copper pipe for larger flow on distribution or commercial runs.

• Check compatibility with copper pipe fittings and copper pipe insulation before you order.

• If the system needs a fixing method or jointing approach, match that to the pipework and the components already specified on site.

Before you order

• Confirm the pipe size, length and quantity you need.

• Check the fixing method and the related parts for the run.

• Add copper pipe insulation if the layout needs protection or thermal control.

• Check stock at your local branch before you order if you want to collect the same day.
