Many rural and commercial premises across Oxfordshire, Northamptonshire, Warwickshire and the Thames Valley rely on oil-fired boilers for heating and hot water.

If you’re operating off the gas grid, or managing multiple properties with oil central heating, keeping those systems safe, efficient and compliant is essential.

At North Oxfordshire Heating, we specialise in commercial oil boiler servicing and maintenance, ensuring consistent performance, fewer breakdowns, and peace of mind for your business.

Why Oil Boiler Servicing Matters.

Without regular servicing, oil boilers can become less efficient and more prone to breakdown.

From soot build-up and dirty nozzles to worn fuel filters and failed sensors, even small issues can impact fuel consumption, heat output and emissions.

Our servicing process helps you avoid unplanned downtime, protects your heating oil system, and extends the life of your boiler. Whether you operate a condensing oil boiler, external oil boiler or older conventional model, we help you keep it in top condition.

What Our Service Includes

Monobloc oil burner

Our engineers carry out full inspections and cleaning of your oil-fired boiler.

This typically includes:

  • Replacing burner nozzles and fuel filters

  • Cleaning heat exchangers and combustion chambers

  • Testing flue gases for safe and efficient combustion

  • Checking tank condition and fuel lines

  • Ensuring controls, thermostats and safety devices operate correctly

You’ll receive a full service report with any recommendations, and we only ever suggest necessary work.

We’re experienced with leading brands including Grant oil boilers, Worcester oil fired boilers, and Bosch oil boilers, and we’re happy to offer advice if you’re unsure about your current system’s condition.
