Common hot water problems, explained
Most hot water troubleshooting comes down to a handful of symptoms — no hot water at all, water that's leaking, pressure that's dropped, water that's only lukewarm, or a gas or electric unit that's stopped working. Each has a short list of likely causes, and knowing which you're looking at means we arrive with the right parts.
These pages walk through the common hot water problems honestly: what's likely causing it, what you can safely check yourself, and where it crosses into licensed gas or electrical work that you should not attempt. Whatever the symptom, the line is attended 24 hours and we prioritise no-hot-water call-outs.

Safe check, or licensed job?
What's safe to check yourself, and what isn't.
A few hot water checks are safe for anyone — looking for an obvious leak, checking the power point or the gas isolation, or relighting a pilot where the manufacturer's instructions allow. Beyond that, hot water involves gas, pressure and electricity, and the repairs must be done by a licensed plumber or gasfitter. If you smell gas, turn the gas off at the meter, don't touch switches, and call us.
