The Real Cost of Oil Boiler Servicing – A Short-Term Saving v Long-Term Risk?
A thorough service takes extra time and may cost a little more, but it’s an investment in reliability. The alternative? A quick, basic service that might save a little upfront but leaves key components unchecked.If everything keeps running, you might save money. But if something fails, the costs can quickly add up:✔️ Emergency call-out fees
✔️ Replacement parts
✔️ A second visit, plus time without heating/hot waterThat’s why I take the time to inspect beyond the basics. My service includes checking key components like the capacitor, solenoid, motor, and pump—parts that might be wearing but aren’t always obvious at a glance. This prevention-first approach means you’re less likely to face sudden breakdowns, costly call-outs, or being left without heating when you need it most.A proper service isn’t just about today—it’s about keeping your oil boiler running efficiently between services.
