Is Your Oil Boiler an Emergency?
Call the emergency line if any of these apply:
• No heating or hot water, especially if there are elderly people, young children or anyone unwell in the house
• Oil leaking from the boiler, the oil line or around the tank
• A strong smell of oil or fumes inside the house
• Smoke or soot coming from the boiler or flue
• The boiler is overheating, banging or making unusual noises
• The boiler keeps going into lockout after you have reset it once
Stay Safe While You Wait
If you can smell fumes, see smoke or the boiler is leaking oil, switch the boiler off at the isolating switch if you can do so safely, open the windows and keep clear of the appliance until I arrive. If anyone feels unwell, with headaches, dizziness or nausea, get them into fresh air and seek medical advice. A carbon monoxide alarm near the boiler is a sensible precaution for every home with an oil boiler.

Common Oil Boiler Faults I Repair
Oil boilers fail in a handful of familiar ways. The cause is not always the boiler itself, so I check the boiler, the oil tank and the oil supply together before recommending a repair.

Oil Boiler Not Firing Up
If your oil boiler will not fire up, the cause is often in the oil supply rather than the boiler. Low or empty oil, a blocked oil filter, air in the fuel line, a worn nozzle, a faulty photocell or failing ignition electrodes can all stop the burner from lighting. I start with the tank level and oil supply, then test the burner and controls until I find the fault.
Oil Boiler Lockout and Resetting
When the lockout light comes on, the boiler's safety control has shut the burner down, usually because it tried to fire and failed. You can press the reset button once. If the boiler locks out again, do not keep pressing reset: repeated attempts can leave unburnt oil in the combustion chamber, which makes the fault worse and can be dangerous. Call me instead and I will find out why it is locking out.
Oil Boiler Keeps Cutting Out
A boiler that fires and then cuts out, or runs for a while and stops, can have a partly blocked filter, a sticking solenoid valve, a dirty photocell, a faulty thermostat or a problem with the oil line. Intermittent faults like this are easier to diagnose early, before they leave you without heating on a cold night.
Oil Boiler Smells of Oil or Fumes
A faint smell for a moment when some burners start can be normal, but a strong or lasting smell of oil, any smell of fumes inside the house, or soot around the boiler is not. It can point to a leak at a fitting, a poorly adjusted burner or a flue problem. Switch the boiler off and call me.
Oil Boiler Not Heating Hot Water
If the radiators are warm but there is no hot water, or the other way round, the fault is usually in the controls rather than the burner: a motorised valve, the programmer or the cylinder thermostat. I test each part and replace only what has failed.
Ran Out of Oil?
Once the tank has been refilled, leave it to settle before restarting the boiler, because the delivery can stir up sediment that blocks the filter. If the boiler still will not fire after one reset, the fuel line has probably drawn in air and needs bleeding. I can bleed the system, check the filter and get the heating running again.
What Happens When You Call
• Call or WhatsApp the 24 hour emergency line on 07743 386540
• I ask what the boiler is doing and give you any safety advice straight away
• I attend and check the boiler, the oil tank and the oil supply together
• I explain the fault and the cost before carrying out the repair
• If a part has to be ordered, I make the system safe and tell you what happens next
Avoid a Winter Breakdown
Most emergency call-outs I attend in winter could have been caught at a service. An annual oil boiler service checks the burner, combustion, safety controls and oil supply, and gives me the chance to replace worn parts before they fail.
See my oil boiler servicing page to book, or read my guide to getting your heating ready for winter.

FAQs
Losing all heating or hot water, an oil leak, a smell of oil or fumes, smoke or soot, or a boiler that keeps locking out are all emergencies. It is particularly urgent if there are elderly people, young children or anyone unwell in the house. If you are not sure, call the emergency line and I will advise you.
Yes. I provide emergency oil boiler repairs 24 hours a day, seven days a week, across Southampton and Hampshire. Call or WhatsApp 07743 386540.
Emergency call-outs start from £150, which includes the first half hour plus travel, then £85 per hour plus parts. Evening repairs start from £190, including the first half hour, then £95 per hour plus parts. I always explain the fault and the cost before carrying out the repair.
Only if they are trained and competent to work on oil-fired appliances. OFTEC registration is the recognised scheme for oil heating engineers. I am a plumber and an OFTEC-registered oil boiler engineer, so I can repair the boiler and the plumbing around it.
Pressing reset once is fine. If the boiler locks out again, stop and call an engineer. Repeated resets can leave unburnt oil in the combustion chamber, which can make the fault worse and create a safety risk.
Wait for the new oil to settle after delivery, then press reset once. If the boiler will not fire, air has probably got into the fuel line and it needs bleeding. Call me and I can bleed the system and check the filter.
A brief smell when the burner starts can be normal on some boilers. A strong or lasting smell, fumes indoors or soot can mean a leak, a burner that needs adjusting or a flue problem. Switch the boiler off and call me.
