We cover Boulter boiler repairs in London, including oil boiler lockouts, no heating, no hot water, burner faults and pressure problems. Some older Boulter boilers can be repaired, but parts availability can vary by model and age. We will advise the safest, most cost-effective next step after inspection.

Safety First

Smell oil or fumes? Turn off the boiler at the controls. Open windows. Do not attempt to restart. Call an engineer.

CO alarm sounding? Stop using the boiler. Open doors and windows. Leave the property. Call 999. If anyone is drowsy, breathless or has a headache, tell the operator. Do not re-enter until you are told it is safe.

Boiler leaking heavily? Turn off the boiler at the controls. If safe, turn off the water supply. Call an engineer.

For gas appliances: If you smell gas, turn off the gas supply at the meter if it is safe to do so. Open windows. Leave the property. Call the National Gas Emergency Service on 0800 111 999.

Quick Checks Before You Call

Before calling an engineer, these safe checks may resolve simple issues with your Boulter boiler.

Check the oil supply

Is there oil in the tank? Check the gauge. If the tank ran dry, air may be in the fuel line.

Check the pressure gauge

Pressure should read around 1.0 to 1.5 bar when cold. If low, top up via the filling loop.

Check the thermostat and timer

Is the room thermostat set above current temperature? Is the heating scheduled to be on?

Try a single reset (oil burner)

If the burner has locked out, locate the reset button on the burner control box. Press once and wait. Do not press more than twice. If it locks out again, call an engineer.

Common Boulter Boiler Faults

Boulter oil boilers use burner lockout indicators rather than digital fault codes. Common symptoms include:

Burner lockout (red light)

Oil burner fails to ignite or flame is lost during operation. May be blocked nozzle, dirty photocell, air in fuel line, or ignition electrode fault. Try one reset. If it locks out again, call an engineer.

Burner fires but no heat

Boiler ignites but radiators stay cold. May be pump failure, airlock, or motorised valve fault.

Pulsating or hunting flame

Flame instability may indicate incorrect nozzle, air supply issue, or fuel pressure problem.

Low pressure

Pressure dropping repeatedly may indicate a leak in the system. An engineer can pressure test to find the source.

Boiler making noise

Rumbling or banging may indicate combustion issues, soot buildup, or sludge in the system.

Note: Boulter oil boilers vary by model and age. Tell us the model and what the burner is doing and we will advise the safest next step.

Not sure which fault you have?

Call with your model and what the burner is doing. We will tell you what is likely involved before anyone attends.

Camray Utility Utility models for kitchen or utility room
Older models Earlier Boulter Camray units

Boulter Camray is now part of Riello. Some parts remain available through Riello and aftermarket suppliers, but older model components may be harder to source.

Repair or Replace Your Boulter Boiler?

Boulter Camray was a well-known UK manufacturer of oil-fired boilers. The brand is now part of the Riello group. Many Boulter boilers installed in the 1990s and 2000s are now 20 to 30 years old. Whether to repair or replace depends on the fault, the model, and parts availability.

When repair may be sensible

  • Minor component failure (nozzle, photocell, electrode, pump)
  • Parts are available and the boiler is under 20 years old
  • First breakdown after years of reliable service

When replacement is often better value

  • Repeat lockouts or multiple faults
  • Major component failure (heat exchanger, burner, control box)
  • Parts are obsolete or require long lead times
  • Boiler is over 25 years old
  • Repair cost approaches a significant share of a replacement quote

We will advise honestly after inspection. There is no pressure to replace if a repair is practical.

Replacement Options

If your Boulter boiler is 20 to 25 years old or parts are difficult to source, a replacement survey is often the fastest route to certainty. See boiler installation London.

Oil vs gas If you currently have an oil boiler and gas is available, switching to gas may reduce running costs and maintenance. We can advise on both options.
Combi vs system boiler We survey your property to recommend the right type, output, and controls for your needs.
Modern efficiency Replacing an older oil boiler with a new condensing unit can significantly improve efficiency and reduce fuel costs.
System protection We recommend a powerflush when fitting a new boiler to remove sludge and protect the new unit.

Annual Servicing

Oil boilers require annual servicing to maintain efficiency and prevent breakdowns. Book a service.

Booked them in for a power flush after ongoing heating issues. The engineer was very thorough and explained what was being done at each stage. We noticed a huge difference in how quickly the radiators now heat up.

Good value for money & was able to sort out my boiler quickly by ordering next day delivery for broken parts. Friendly, punctual service and laid out all the costs beforehand which was helpful. Would recommend.
