Most gas hot water faults show signs before the system stops working completely. Arranging a repair at the first sign of trouble can help prevent a more serious breakdown.

Once a year is the usual interval for a gas unit, and the relief valve is worth checking at the same time. Regular servicing catches a failing thermostat or valve before it takes the hot water out completely.
Most gas systems run for around 10 to 15 years with servicing, and continuous flow units often reach the upper end of that. Water quality, the unit’s position and how hard it works all change the result.
A unit under about 10 years old with a failed thermostat, valve or igniter is usually worth repairing. Past that, or where the tank itself is leaking, replacement is normally the better spend, and we tell you which one applies before the work starts.
Yes, provided the property has a gas connection or can take one. OPG Services removes the old unit, runs or upgrades the gas line, installs the new system and completes the compliance work as one job.
The price depends on the type and size of unit, the condition of the existing gas and water lines, and access to the installation point. We quote on site for free and confirm the full cost before any work begins.
In most cases, yes. We run 24/7 emergency plumbing with same-day attendance, and the vans carry the parts that cause the majority of gas hot water breakdowns.
