Cascade Water Services: Your Accredited Self-Lay Provider in London

At Cascade Water Services Ltd we take pride in being an accredited Self-Lay Provider for water main connections and service connections in London and Hertfordshire. We offer efficient, cost-effective solutions for water infrastructure that comply with industry standards and regulations.

What is a Self-Lay Provider?

As an accredited Self-Lay Provider, Cascade Water Services delivers contestable self-lay works — installing and connecting new water mains and service connections — on behalf of developers, contractors and property owners, and coordinates the adoptable design and approvals alongside them. It is an alternative to waiting on the incumbent water company’s own programme, and it usually gives you far more control over the dates.

Our self-lay services in London

• Water main connections. Installation of new water mains for a property or a whole development.
• Service connections. Connections from the main to individual properties, to the standard the water company will adopt.
• Infrastructure design and planning. Design work that satisfies the regulatory requirements before anything is built.
• Maintenance and repairs. Ongoing support for mains and service connections after handover.

Why choose Cascade for self-lay in London

• Accredited expertise. We are WIRS-accredited to undertake eligible self-lay and contestable works within our accredited scope, with the asset built to be adopted at the end.
• Local knowledge. Extensive experience across London means we understand the constraints of urban water infrastructure — congested corridors, permits and live streets.
• Cost-effective. Self-lay introduces competition into work that is otherwise single-source.
• One point of contact. Design, application, installation and certification under one contract.

Serving the London community

We support residential, commercial and development projects across the capital. Whether you are a developer needing water mains installation or a property owner requiring a new service connection, we have the accreditation and the resources.
