The pipework that keeps your home warm. We keep it working.
The copper pipework running behind your walls, under your floors and connecting your boiler to your radiators and hot water cylinder is a precision system. Every modification — moving a radiator, adding a new one, changing the cylinder position — needs to be done correctly, or you'll end up with imbalanced heating, leaks or a boiler that struggles to perform.
We're heating engineers, not plumbers. We understand system pressure, flow rates, water chemistry and how every change to your pipework affects the rest of the system. Every job is tested, balanced and left working properly before we leave.
Radiator Relocation
Moving a radiator to a new position during a renovation, to clear a doorway or improve a room layout. We cap the old connections, run new pipework to the new position, fit and balance the radiator, and pressure-test the system before we leave.
Adding a New Radiator
Extending into a loft, building an extension or fitting out a new room? We design and run the pipework to the new space, fit the radiator and balance it against the existing system so it heats properly without starving other rooms.
Radiator Upgrades
Swapping old cast-iron radiators for modern double-panel units, upgrading to larger radiators for better heat output, or switching standard TRVs for smart TRVs — we handle the full installation including system rebalancing.
Radiator & Heating Leaks
A dripping radiator valve, a pinhole in a pipe joint or a weeping connection — all need prompt attention to avoid damage. We trace, isolate and repair heating leaks, then re-pressurise and balance the system.
Cylinder Relocation
Moving a hot water cylinder from an airing cupboard to a loft, or repositioning it as part of a larger renovation — we handle the full pipework reroute, including primary flow and return, cold feed, vent pipe and all connections.
Cylinder Replacement
Replacing an old direct cylinder with a modern indirect unit, upgrading to a larger capacity, or swapping an open-vented cylinder for a pressurised (unvented) system — we carry out the full installation including all pipework and controls.
Adding a Hot Water Cylinder
Converting from a combi boiler to a system with a separate hot water cylinder — perhaps for a larger household or as part of heat pump preparation — requires significant pipework changes. We design and carry out the full system conversion.
System Flush & Treatment
Before or after cylinder work, we flush and chemically treat the system to remove sludge and scale buildup. We fit a magnetic filter where appropriate and dose with corrosion inhibitor — essential for system longevity.
Open-Vented to Pressurised
Converting an older gravity-fed, open-vented system to a modern sealed, pressurised system — removing the feed and expansion tank, replacing the cylinder and reconfiguring the pipework. A significant upgrade that makes the system easier to maintain and compatible with modern boilers.
Pipework for Boiler Moves
If your new boiler needs to be positioned in a different location from the old one — moved from an airing cupboard to an outside wall, or from a kitchen to a utility room — we run all the new flow, return and gas pipework to the new position.
Preparing your heating system for a heat pump.
Future-proofingHeat pumps are fundamentally different from gas boilers. They produce lower-temperature water — typically 45–55°C rather than 70–80°C — and need to run for longer periods to heat a home efficiently. This means your existing pipework and radiators may not be adequate without modification, and getting the preparation right is essential to the heat pump performing as it should.
There's not much call for heat pumps in our area at the moment, but we are all heat pump trained and qualified so we can carry out the heating system work that makes a home ready for one. This is often the part that gets overlooked when heat pumps are sold or installed. Poor planning and preparation is a major reason why some heat pump installations underperform.
Pipework Upsizing
Heat pumps require higher flow rates than gas boilers to distribute low-temperature water efficiently. Pipework that is adequate for a gas boiler may be undersized for a heat pump — we assess and upsize where needed.
Radiator Upgrades for Low-Temperature Heat
A standard radiator designed for 70°C water may not be able to heat a room adequately at 45°C. We assess your existing radiators and upsize the ones that won't perform, replacing them with larger panels or low-temperature fan-assisted units.
Hot Water Cylinder Upgrade
Heat pumps require a larger, well-insulated hot water cylinder — typically 200–300 litres — with a large-area coil designed for low-temperature operation. We supply and fit the right cylinder and all associated pipework.
Flow, Return & Balancing
Heat pump systems require careful pipework layout and balancing to operate efficiently. We design the distribution pipework correctly and balance the system so every radiator receives the right amount of water at the right flow rate.
Is your home heat pump ready?
A typical gas-heated home needs several things sorted before a heat pump will perform well. We can assess your current system and tell you exactly what needs to change — and carry out the work to get you there.
- Pipework sized for higher flow rates (typically 22mm or 28mm in main circuits)
- Radiators sized for low-temperature output (45–55°C flow temperature)
- A correctly sized, low-temperature cylinder (usually 200L+) with a large heating coil
- A clean, well-flushed and dosed heating system (sludge causes problems at lower temperatures)
- Buffer vessel or low-loss header where required by the heat pump manufacturer
- Correct zone valves and controls for heat pump operation
How a radiator move or addition works
Survey & plan
We discuss what you need and agree the new position, pipe routing and any constraints — particularly if the work needs to be coordinated with other trades (plasterers, decorators, flooring contractors).
Isolate, drain and cap
We isolate the relevant part of the system, drain it down if required, and cap the existing connections cleanly. If we're moving a radiator, we do this first before making any openings in walls or floors.
Run new pipework
We run the new copper pipework to the required location, keeping runs as clean and direct as possible. We work with your decorator's timetable — if plastering is happening, we coordinate so the pipework goes in before the walls are closed.
Fit, refill & pressure test
We fit the radiator, refill the system, purge any airlocks and re-pressurise to the correct operating pressure. We test for leaks at every new joint before we consider the job done.
Balance & sign off
We balance the system so the new radiator heats properly without starving other rooms, check the boiler pressure and controls are correct, and confirm everything is working before we leave.
