Oil heating checked from tank to controls
Fuel route investigated
We check supply issues as well as faults within the boiler itself.
Combustion performance tested
We assess burner operation and confirm settings after the work.
Warning signs explained
We help you understand soot, noise, lockouts and rising oil use.
Act on soot, lockouts and poor heating
An oil boiler that locks out, smokes or leaves soot needs attention rather than another hopeful press of the reset button. Fuel smells, increased oil use, poor heating and unusual burner noise can also signal a problem. We diagnose the burner, ignition components, fuel line, controls and oil supply before recommending a repair. Our oil boiler servicing and repair process is methodical because similar symptoms can come from different causes. We explain what we've found before corrective work proceeds.
Support clean and dependable combustion
Routine servicing covers combustion performance, burner condition, filters, nozzle, heat exchanger and safety controls. Cleaning and adjustment can reduce deposits and support efficient burning, while inspection may reveal worn parts before they cause a breakdown. After a service or repair, we test combustion and check the complete system in operation. That final stage confirms the burner, heating and controls are responding as expected instead of leaving you to discover the answer on the next cold morning.
Frequently asked questions
Why does our oil boiler keep locking out?
A lockout can follow a fuel supply issue, ignition fault, burner problem or another condition the controls have detected. We check the oil route and boiler components to identify the cause before recommending repair.
What does an oil boiler service cover?
We inspect and service relevant burner parts, filters, nozzle, heat exchanger, controls and combustion operation. The exact work depends on the boiler, its condition and what we find during checks.
Is smoke or soot around an oil boiler normal?
No. Smoke or soot can indicate poor combustion or another fault and should be checked. We assess the burner, fuel supply and boiler condition, then test combustion after any servicing or corrective work.
