Common Boiler Problems We Fix in Sevenoaks

Our engineers diagnose and repair a wide range of boiler faults daily. Some of the most common issues we deal with across Sevenoaks include:

No Heating or Hot Water

A complete loss of heating or hot water is the most common reason homeowners call us. The cause can vary — from a faulty diverter valve or broken motorised valve to a failed pump or a tripped thermostat. Our engineers will identify the root cause quickly and carry out the repair, or advise you honestly if a replacement is the more cost-effective option.

Low Boiler Pressure

If your boiler pressure gauge is reading below 1 bar, your boiler may lock out or fail to fire. Low pressure is often caused by a small leak in the system, a recently bled radiator or a faulty pressure relief valve. We will locate the cause, carry out any necessary repairs and re-pressurise the system correctly.

Boiler Lockout & Error Codes

Modern boilers display fault codes when something goes wrong. While some lockouts can be resolved with a simple reset, persistent fault codes usually indicate an underlying problem that requires attention. Our engineers are familiar with the fault code systems used by all major manufacturers and will diagnose the issue accurately, rather than simply resetting and leaving.

Banging, Kettling or Gurgling Noises

Unusual noises from your boiler or heating system are often a sign that something needs attention. Kettling — a rumbling or banging sound similar to a boiling kettle — is usually caused by limescale or sludge build-up on the heat exchanger. Gurgling noises can indicate trapped air or low water pressure. We will diagnose the cause and recommend the most appropriate fix, which may include a power flush of the heating system.

Pilot Light or Ignition Failure

If your boiler fails to ignite or the pilot light keeps going out, this can be caused by a faulty ignition lead, a dirty or damaged flame sensor, a problem with the gas supply or a fault with the PCB (printed circuit board). Our engineers will carry out a full inspection and replace the faulty component to restore reliable operation.

Leaking or Dripping Boiler

A leaking boiler should never be ignored. Depending on where the leak is coming from, it could indicate a failed pump seal, a corroded pipe connection, a faulty pressure relief valve or a cracked heat exchanger. We will identify the source of the leak and carry out the appropriate repair promptly to prevent further damage to your boiler and your property.

Should You Repair or Replace Your Boiler?

This is one of the most common questions we are asked, and the honest answer depends on the age of your boiler, the nature of the fault and the likely cost of the repair. As a general guide, if your boiler is less than eight to ten years old and the repair is straightforward, fixing it is usually the right choice. If it is older, breaking down regularly or facing an expensive repair, a new boiler installation may be the more cost-effective long-term solution.

At Newbery Plumbing & Heating, we will always give you our honest opinion. We will never recommend an unnecessary replacement when a repair is the sensible option — and equally, we will tell you plainly if we believe your money is better spent on a new boiler. If a replacement is the right route, we can provide a competitive quote for a full boiler installation at the same time.

Prevent Breakdowns With Annual Boiler Servicing in Sevenoaks

The best way to avoid a costly boiler repair is to have your boiler serviced every year by a Gas Safe registered engineer. An annual service allows us to spot minor issues before they develop into major faults, check that the boiler is operating safely and efficiently, and ensure that your manufacturer’s warranty remains valid. We offer annual boiler servicing across Sevenoaks and the wider Kent and Surrey area, and we recommend booking in the spring or summer months so your system is in peak condition before the heating season begins.

FAQ's

How quickly can you respond to a boiler breakdown in Sevenoaks?

In most cases, we can offer a same-day or next-day appointment across Sevenoaks and the surrounding area. For genuine emergencies — such as a complete loss of heating or hot water, or a suspected gas leak — we offer 24-hour emergency call-outs. Simply give us a call, and we will do our very best to have a Gas Safe-registered engineer with you as quickly as possible.

How much does a boiler repair cost in Sevenoaks?

The cost of a boiler repair depends on the nature of the fault and any parts that may be required. We always carry out a diagnostic check first and provide a clear, upfront quote before any repair work begins, so there are no hidden surprises. Minor repairs — such as replacing a faulty thermocouple or repressurising the system — will cost considerably less than replacing a heat exchanger or PCB. Contact us for a no-obligation assessment, and we will give you an honest, accurate quote.

Do you repair all makes and models of boilers?

Yes — our engineers are experienced in repairing all major boiler brands, including Worcester Bosch, Vaillant, Baxi, Ideal, Glow-worm, Potterton, Viessmann and many others. We carry a wide range of common replacement parts, which helps us to complete most repairs in a single visit without the need to order parts and return.

My boiler keeps breaking down — is it worth repairing?

If your boiler is breaking down repeatedly, it is worth having an honest conversation about whether repair or replacement is the better long-term option. As a general guide, if the repair costs more than half the price of a new boiler, or if your boiler is over ten to fifteen years old and facing multiple faults, a replacement is often the more cost-effective solution. We will always give you our honest assessment and will never recommend unnecessary work. If a new boiler is the right route, we can provide a competitive installation quote at the same time.

Is it safe to use my boiler if it is making strange noises?

Unusual noises from your boiler — such as banging, kettling, gurgling or whistling — are usually a sign that something is not right, and it is advisable to have it checked by a Gas Safe registered engineer as soon as possible. While some noises are caused by relatively minor issues such as trapped air or low pressure, others can indicate a more serious fault that could worsen if left unattended. If you have any concerns about the safety of your boiler, switch it off and call us straightaway.
