Gas engineers generate a genuinely steady stream of scrap through boiler swaps, pipework replacement, and general servicing work — material that's easy to overlook as "just offcuts" rather than something worth treating properly.
What a typical gas engineering job generates
- Copper pipe — from pipework replacement and boiler installation, generally a high-value grade if kept clean
- Brass fittings — valves, connectors, and components removed during a swap
- Old boiler components — some boilers contain a meaningful amount of recoverable copper in their internals, easy to miss if the whole unit goes straight to general waste
Why copper and brass need to stay separate
These two materials are priced very differently — copper consistently commands more than brass. Mixed together in one bag or bin, a buyer will typically grade the whole lot conservatively rather than sort it themselves, meaning genuinely valuable copper can end up priced as if it were brass. Keeping two separate containers on the job, one for each, costs nothing and protects the value of both.
Old boilers: worth checking, not just skipping
It's easy to treat an old boiler as pure waste once it's disconnected, but many contain enough internal copper to be worth checking before disposal — a few minutes' inspection before it goes in the van can be the difference between genuine scrap value and nothing at all.
Building it into a regular job, not a special trip
For engineers doing this work consistently, the value compounds fastest when scrap handling becomes part of the normal routine on every job — a dedicated space in the van for copper and brass specifically, rather than sorting through general job waste afterward.
Getting a fair price
The same principle applies here as with any trade generating scrap regularly: a single yard sets one price with no competitive pressure to offer their best rate. Getting multiple buyers to quote on the same load, particularly on genuinely valuable material like copper pipe, consistently produces a better outcome than defaulting to whichever yard is most convenient.
