Quick Checks (60 Seconds)

Before assuming the worst, try these basic checks:

1. Check your fuse box: a tripped breaker can look like a boiler failure.
2. Check thermostat and timer: settings can reset after power cuts; replace batteries in wireless controls.
3. Check the pressure gauge (if fitted): if pressure is low, follow our pressure guide.
4. Check oil level (oil boilers): if you have an oil tank, check you haven’t run out of fuel.
5. Reset once only: if the boiler locks out again after resetting, stop and call us.

The Reality About Boulter Boilers

Boulter was a UK boiler brand best known for Boulter Camray oil boilers. The brand has been discontinued for many years. If you still have a Boulter boiler, it’s well past its expected lifespan.

Here’s the honest situation:

• Parts availability: Boulter-specific parts are essentially unavailable. Some generic components may work, but brand-specific items are long gone.
• Age: any Boulter boiler still running is typically 20+ years old – well beyond the usual domestic lifespan.
• Efficiency: older non-condensing boilers are typically far less efficient than modern condensing boilers (real-world performance varies by model, system condition, and controls).
• Safety and support: older boilers often lack modern safeguards and can be harder to maintain reliably when parts are scarce.

Our honest view: if your Boulter boiler has failed, replacement is almost certainly the right answer. Attempting repairs on obsolete equipment usually means throwing money at a unit that will fail again soon.

Oil or Gas? Check Your Fuel Type

Most Boulter boilers (particularly the Camray range) were oil-fired. If you have an oil tank on your property, you have an oil boiler.

• Oil boilers require an OFTEC registered engineer for servicing and repairs.
• Gas boilers require a Gas Safe registered engineer.

If you’re in London and have mains gas available, switching from oil to gas is often the most practical long-term solution.

Common Boulter Boiler Problems

Typical faults on aging Boulter boilers:

• Ignition failure: burner issues, electrode problems, or control faults.
• No hot water: diverter valve failure or heat exchanger problems.
• Leaking: corroded heat exchangers, failed seals, or pump issues.
• Cutting out: overheating due to sludge build-up or circulation problems.
• Strange noises: kettling, banging, or gurgling from limescale or sludge accumulation.
• Oil-specific issues: blocked nozzles, air in fuel line, or tank sludge (oil models).

What We Check on Arrival

If we attend a Boulter boiler, our engineer will typically:

• Confirm the exact model, fuel type, and approximate age from the data plate
• Inspect for leaks, corrosion, scorching and flue/ventilation issues
• Check system pressure, pump operation and heating controls
• Test safe operation and basic performance checks where appropriate
• Assess whether any compatible parts are realistically available
• Give a clear recommendation: repair feasibility vs replacement economics

Note: For oil-specific burner work, you may need an OFTEC registered engineer. We can help you identify the right next step.

What Happens When You Call Us

Here’s our approach to Boulter boiler enquiries:

1. We confirm your fuel type: oil or gas – this determines who can work on it.
2. We understand the symptoms: no heat, no hot water, leaking, strange noises, error codes.
3. We give you the honest answer: with obsolete boilers, that’s usually “replacement is the smart move.”
4. We provide options: a clear, fixed-price quote for a new boiler that suits your property and budget.
5. You decide: no pressure, just honest guidance.

Why Boulter Boilers Are Found in London Properties

We occasionally encounter Boulter boilers in London, typically in:

• Older detached properties: larger homes that originally used oil heating.
• Edge-of-London areas: where mains gas wasn’t always available historically.
• Properties with deferred maintenance: the boiler kept working, so replacement was postponed.
• Commercial conversions: buildings with legacy heating systems.

If your Boulter is still running, you’ve had exceptional value from it – but now is the time to upgrade before an emergency failure leaves you without heating.

Repair vs Replace: The Numbers

With obsolete boilers, the maths almost always favours replacement.

Example repair scenario (illustration only): A call-out, diagnosis, and attempted repair could cost £400-600+ – and that’s if compatible parts can be sourced. Oil boiler repairs often cost more due to specialist requirements.

• Brand-specific parts are generally unavailable.
• Generic alternatives may not be a perfect fit.
• Another component will likely fail soon on a 20+ year old boiler.
• Repairs on legacy equipment usually come with limited reassurance compared to a new install warranty.

Compare that to replacement: A new gas boiler from £1,899 gives you a warranty-backed unit with long-term support, plus typically lower running costs than oil.

Landlords: Obsolete Boilers Are a Risk

If you’re a landlord with a Boulter boiler in a rental property, replacement should be a priority:

• Tenant satisfaction: breakdowns cause complaints, void periods, and emergency call-out costs.
• Compliance confidence: modern boilers are easier to maintain and certify.
• Predictable costs: a new boiler with warranty beats reactive repairs on obsolete equipment.
• EPC improvement: a modern efficient boiler can help your property’s energy rating (property-specific factors apply).

We support landlords across London with Gas Safety Certificates (CP12) and planned boiler upgrades. See our London landlord checklist.

Still Want to Explore Repair?

We understand. If you want a diagnosis first, we can assess the fault and confirm whether any repair is possible.

For oil boilers, we can help you identify the system and point you towards the right next step, including recommending an OFTEC engineer where needed. But we’ll be straight with you – if repair means throwing money at a boiler that’s going to fail again, we’ll tell you that honestly.
