Plumbing, heating & gas for your home extension
Everything your extension needs, done right
We handle all the plumbing, heating, and gas work your extension requires — coordinated across one trade, on your schedule, and working alongside your builder from first fix through to completion. All work is carried out to Building Regulations standards, Gas Safe certified where required, and properly documented for sign-off.
- Gas Safe registered
- WaterSafe registered
- Building Regulations compliant
- 14-strong directly employed team
Plumbing first & second fix
New hot and cold supply throughout your extension, connected to your existing system and pressure-tested before the walls go on.
Heating system extension
Extending your existing central heating with new radiators, pipework, and zone valves — or advising when a system upgrade makes more sense.
Underfloor heating
Wet underfloor heating systems for ground-floor extensions — efficient, invisible, and ideal for open-plan kitchen and dining spaces.
Gas supply & appliances
New gas points for cooker hobs, range cookers, or gas fires — fully Gas Safe certified and notified to Building Control.
Boiler upgrade
If your existing boiler can't handle the additional load, we'll advise on the right upgrade and carry out the full installation as part of your project.
Bathroom & en-suite
Full plumbing installation for new bathrooms, en-suites, or WCs added as part of a loft conversion, side return, or ground-floor extension.
Waste & drainage
Connecting new waste runs to your existing drainage, including soil stacks and inspection chambers where the project requires it.
Unvented hot water
G3-certified unvented cylinder installation for homes where an extension increases hot water demand beyond what a vented system can deliver.
Why choose us
Qualified. Coordinated. On schedule.
We know extension projects move fast and that your builder needs trades who turn up as agreed and get the work signed off cleanly. That's what we do.
