Signs Your Rainham Gas Boiler Is Overdue a Service
Don’t wait until something stops working. Book sooner rather than later if any of the following apply:
No service in the last 12 months
Gas bills rising without any increase in usage
Radiators slow to warm up or unevenly heated
Boiler cutting out or losing pressure between top-ups
Unusual sounds — kettling, rattling, humming, or gurgling
Moved into a Rainham property with no boiler service history on record
Catching small faults during an annual service consistently costs far less than dealing with a breakdown.
