Outbuilding Water Connection

What an outbuilding water connection can include

A proper outbuilding supply is more than “running a pipe outside”. It is designed for durability, access and long-term reliability.

• Connecting a new water feed from the existing supply (where suitable)
• Routing pipework externally or underground to the outbuilding
• Installing internal pipework for a cold tap, sink, WC or appliance feed
• Fitting isolation valves so the outbuilding supply can be shut off independently
• Protecting pipework against frost and weather exposure (insulation and correct pipe choice)
• Repairing leaks on exposed or buried external pipework
• Replacing degraded sections and improving pipe supports and protection
• Pressure and leak testing before handover
• Advice on backflow protection where required (for example, certain hose or equipment setups)

When this service is most useful

This service is a good fit if you want reliable water in a garage, workshop, garden office, utility outbuilding or small commercial unit. It is also common for landlords who need a robust, easy-to-isolate supply that reduces the risk of leaks and winter damage. If you are currently relying on a hose, experiencing low pressure at an outside tap, or dealing with repeated freezing, a properly installed connection is usually the next step.

How the work is typically delivered

The job normally starts with a practical assessment of the existing water supply, pressure, and the best route to the outbuilding. Pipe sizing, isolation points, and protection measures are then agreed before work begins. Once installed, the connection is tested for leaks and correct operation, and you are shown how to isolate and drain down the outbuilding line if needed.

After installation: keeping it reliable

You will have a clear shut-off point for the outbuilding supply, which makes maintenance and winterisation simpler. If the outbuilding is left unheated in winter, you may be advised on insulation upgrades and safe drain-down options to reduce the risk of freezing. If you later add fixtures or change how the space is used, the pipework can be adapted to suit.
