Our Oil Boiler Repair Services

When it comes to oil-fired systems, you need an engineer who understands their unique components — from burners and fuel lines to tanks and filters. Our engineers carry out comprehensive repairs on both internal and external oil boilers, using genuine manufacturer parts for reliability and safety. Our oil boiler repair services include:

No Heat or Hot Water

If your boiler won’t fire, it could be due to an ignition fault, burner issue, or fuel supply problem, and our OFTEC engineers can diagnose and repair it to restore reliable heating.
Inconsistent Hot Water

If your radiators or taps aren’t heating properly, this may be caused by leaks, air in the system, or pressure problems, which we can quickly correct.
Leaks or Drips from Pipes or Tank

If you notice oil drips, it’s often due to worn pipework, faulty seals, or tank degradation, and we can locate and repair the leaks safely.
Strange Noises

If your boiler makes unusual noises, it could be a blocked burner, trapped air, or combustion issue, which we identify and fix for smooth operation.

Error Codes or Fault Messages

If your boiler is showing fault codes, they usually indicate component failures, ignition faults, or control problems, which we can diagnose and repair.
Slow or Failed Ignition

If your boiler takes too long to light or won’t ignite, this is often caused by dirty burners, blocked nozzles, or fuel flow problems, which we clean, repair, or replace.
Poor Flame or Smoke Issues

If you see black smoke or a poor flame, this can indicate incomplete combustion or restricted fuel flow, which we optimise for safe, efficient operation.
Heating Controls Not Responding:

If your thermostats, timers, or programmers aren’t working, they may be faulty, and we can repair or replace them so your system responds accurately.

Outdoor Boiler Issues

If your outdoor or garage boiler isn’t working, it may be affected by weather, corrosion, or electrical faults, and we service and repair it with full safety checks.
Intermittent Heating Performance

If your heating or hot water comes and goes, it’s often caused by fuel delivery issues, blockages, or pump faults, which we can inspect and fix.
Boiler Running Inefficiently

If your boiler is using more fuel than usual or struggling to heat your home, it may have poor combustion, soot build-up, or worn components, which we can test and repair to improve efficiency.
Emergency Situations

If your boiler has completely broken down, we provide rapid, same-day repair from our OFTEC-registered engineers to get your heating and hot water back quickly.

No matter what kind of problem you’re facing, we’ll arrive promptly, explain what’s wrong in plain English, and offer a fair, upfront repair quote — so you’re never left guessing.

Why It’s Important to Maintain Your Boiler & Heating System

Your boiler works quietly in the background all year, but when something goes wrong, it can affect more than just your comfort.
Here’s why regular maintenance and timely repairs are so important:

Safety First

Faulty boilers can leak carbon monoxide (CO) — an odourless, colourless gas that can be deadly. Regular servicing by an OFTEC registered Oil Heating engineer ensures all safety devices, seals and ventilation are working properly, protecting your household.
Minor Faults Can Grow

Minor faults, if ignored, can develop into serious issues that shorten your boiler’s lifespan. Timely attention from a qualified engineer can often add years to your system’s life and delay costly replacements.
Energy Efficiency

A poorly maintained boiler has to work harder, wasting fuel and increasing your energy bills. Keeping your system clean and tuned helps it run efficiently, often reducing heating costs by up to 10–15%.
Protecting Your Warranty

Many boiler manufacturers require annual servicing by a qualified engineer to maintain warranty cover. Skipping maintenance could void your warranty and leave you paying for repairs out of pocket. Keeping your boiler healthy isn’t just about heat — it’s about safety, efficiency, and peace of mind.
