Copper or Plastic Pipework for Heating and Plumbing
Copper and modern plastic pipe (typically PEX or similar) both do the job reliably when installed correctly; the choice usually comes down to the specific run rather than a blanket preference for one material..

The case for copper
Exposed pipework, higher-temperature runs close to a boiler, and situations where appearance and rigidity matter favour copper's proven track record.
The case for plastic
Concealed runs under floors or through walls benefit from plastic's flexibility, fewer joints and resistance to frost-related splitting.
Which wins when
We often use both on the same job: copper near the boiler and visible runs, plastic for concealed distribution pipework — matching material to location rather than picking one for the whole house.
Questions we get asked
Is plastic pipe as durable as copper?
Modern plastic pipe systems are durable when installed to the manufacturer's specification, though they're generally used for different parts of a system than copper rather than as a direct swap.
Can copper and plastic be joined together?
Yes, with the correct transition fittings, and it's a normal part of most heating installations.
Does pipe material affect water quality?
Both are approved for potable water use when the correct grade of pipe and fittings are used.
