    An Unbeatable Selection Of Plastic Pipes

    We stock high-quality plastic pipes from leading manufacturers, offering a wide choice of sizes, coil lengths and system types to suit a variety of plumbing and heating applications.

    Coiled Barrier Pipes

    Coiled barrier pipes are widely used in plumbing and heating installations where flexibility and long continuous runs are required. Designed with an oxygen barrier layer, these pipes help prevent air ingress into heating systems, protecting components such as radiators and boilers from corrosion. Popular options include the Qual-PEX Plastic Barrier Pipe Coil 15mm x 50m, the JG Speedfit Coiled Barrier Pipe 15mm x 50m and the PolyPlumb Barrier Pipe Coil 15mm x 100m for larger installations. Layflat coils such as the JG Speedfit Barrier Pipe Layflat Coil 22mm x 50m are also available for easier handling on-site.

    Straight Barrier Pipes

    Straight barrier pipes are ideal for installations requiring rigid, pre-cut lengths, providing a neat, structured pipe run. They are commonly used in exposed pipework. Our range includes the JG Speedfit Barrier Pipe Straight 22mm x 3m, the PolyPlumb Barrier Pipe Straight 15mm x 3m and the Qual-PEX Plastic Barrier Straight Pipe 22mm x 3m. Longer lengths, such as 6m, are also available for larger projects.

    Barrier Pipe Coils (Hep2O System)

    Barrier pipe coils from systems such as Hep2O are designed for quick, push-fit installations and are widely used in domestic plumbing and heating systems. Popular products include the Hep2O Barrier Pipe Coil 15mm x 50m, the Hep2O Barrier Pipe Coil 22mm x 50m and the Hep2O Barrier Pipe Coil 10mm x 100m. These coils are suitable for both hot and cold water systems and are commonly used in refurbishment and new-build projects.

    Pipe-in-Pipe Systems

    Pipe-in-pipe systems provide an added layer of protection by housing the main pipe within a conduit sleeve. This design is ideal for installations within floors, walls or concrete, allowing for movement and easier replacement if required. Options include the Qual-PEX Pipe-in-pipe 15mm x 50m and the Qual-PEX Pipe-in-pipe 22mm x 25m, both suited to underfloor heating and concealed pipework applications.

    Conduit Pipes & Ducting

    Conduit pipes and ducting are used to protect pipework and allow for safe routing through walls, floors and other structures. These systems are particularly useful in installations where pipe protection or future accessibility is required. Products such as Conduit Ducting for Pipes 15mm x 50m and Conduit Ducting for Pipes 22mm x 50m provide flexible protection, while JG Speedfit Conduit Pipe 15mm x 25m and 22mm x 50m options are designed for compatibility with push-fit systems.

    Flexible Polybutylene Pipes

    Flexible polybutylene pipes are commonly used in domestic systems due to their ability to bend around obstacles and reduce the need for extra fittings. Popular options include Flexible Polybutylene Pipe 15mm x 50m, Flexible Polybutylene Pipe 22mm x 25m, and straight lengths such as Flexible Polybutylene Pipe 15mm x 3m, all suitable for hot and cold water systems.

    Plastic Pipe Materials Explained

    Plastic plumbing pipes are typically manufactured from materials such as polybutylene and cross-linked polyethylene (PEX), both designed for durability, flexibility and resistance to corrosion. Polybutylene pipes are widely used in domestic plumbing and heating systems due to their flexibility and ease of installation, while PEX-based barrier pipes include an oxygen barrier layer to prevent air ingress into heating systems.

    Barrier pipes are particularly important in central and underfloor heating systems, as they help protect metal components, such as radiators and boilers, from corrosion.

    Choosing Plastic Pipes for Different Applications

    Different types of plastic pipe are suited to specific applications depending on temperature, pressure and installation method. Barrier pipes are commonly used for central heating and hot water systems, while pipe-in-pipe systems provide additional protection when pipes are installed within floors or walls. Conduit and ducting systems are ideal when pipework needs to be shielded or easily replaced.

    Most modern plastic pipes are suitable for both hot and cold water systems, but it is important to consult the manufacturer’s specifications for temperature and pressure ratings before installation.

    WRAS Approved Plastic Pipes

    Many plastic pipes used for potable water systems are WRAS approved. WRAS approval confirms that a product meets UK water supply regulations and is safe for use with drinking water.

    Installing Plastic Pipes & Compatibility

    Plastic pipes are designed for quick and efficient installation, often using push-fit or compression fittings depending on the system. Brands such as JG Speedfit and Hep2O offer fully compatible pipe and fitting systems for straightforward installation. When selecting pipework, it is important to ensure compatibility with existing fittings and to check pipe diameter, coil length and system requirements.

    FAQs

    What are the best plastic pipes for hot water systems?

    Most modern plastic pipes are suitable for hot water systems, particularly barrier pipes made from polybutylene or PEX. These are designed to handle high temperatures while maintaining flexibility and durability. Brands such as PolyPlumb, JG Speedfit and Qual-PEX offer reliable options for both hot and cold water applications.

    What is the difference between Polybutylene and PEX pipes?

    Polybutylene pipes are highly flexible and easy to install, making them ideal for domestic plumbing systems. PEX-based barrier pipes include an oxygen barrier layer, which helps prevent corrosion in central heating systems by preventing air from entering the system.

    Which plastic pipe system is easiest to install?

    Push-fit systems are generally the quickest and easiest to install because they do not require soldering or specialist tools. Systems such as Hep2O and JG Speedfit are designed for fast, secure connections, making them a popular choice among professionals and DIY installers alike.

    What is WRAS approval and why is it important?

    WRAS approval confirms that a product meets UK water regulations and is safe for use with drinking water.

    Are plastic pipes suitable for central heating systems?

    Yes, barrier plastic pipes are widely used in central heating systems. Their oxygen barrier layer helps prevent corrosion within the system, improving longevity and efficiency. Brands such as PolyPlumb, Qual-PEX and PolyFit offer suitable options for heating installations.

    Can plastic pipes be used for underfloor heating?

    Plastic pipes are commonly used in underfloor heating systems due to their flexibility and ability to handle continuous runs without joints. Pipe-in-pipe systems and barrier pipe coils are particularly suitable for this type of installation.

    Do I need special fittings for plastic pipes?

    Yes, plastic pipes require compatible fittings depending on the system being used. Many brands offer their own push-fit or compression fittings designed specifically for their pipe range. It is important to check compatibility before installation to ensure a secure and leak-free connection.

    What is pipe-in-pipe and when is it used?

    Pipe-in-pipe systems consist of a carrier pipe within a protective outer sleeve. This design is used where pipes are installed within floors or walls, allowing for movement and easier replacement if required. It also provides added protection during installation.

    Which brands of plastic pipes are most reliable?

    Trusted brands such as PolyPlumb, Hep2O, Qual-PEX, PolyFit and JG Speedfit are widely used across the UK. Each offers a range of pipe types and systems designed for different applications, from domestic plumbing to underfloor heating.
