If your boiler pressure keeps dropping, it may be due to a leak, a faulty valve, or an issue with the expansion vessel. You can try topping up the boiler pressure by turning the filling loop valve (usually a silver or braided hose) until the pressure gauge reaches the recommended level, typically 1–1.5 bar. If the pressure continues to drop after topping up, please call us. This indicates a fault that requires a qualified Gas Safe engineer like Russell Haskins to inspect and repair the boiler safely.

If your boiler is making banging, whistling, gurgling, or other unusual noises, it could be a sign of underlying issues such as trapped air in the system, limescale buildup on the heat exchanger, or pressure problems. While some minor sounds can occur occasionally, persistent or loud noises should never be ignored, as they can lead to further damage or a breakdown. Turn off the boiler to prevent potential damage and check the pressure gauge. If the pressure is normal but the noises continue, it’s best to contact us. Our Gas Safe registered engineers will quickly diagnose the problem and carry out any necessary repairs, ensuring your boiler runs safely, quietly, and efficiently.

The duration of a boiler repair depends on the nature and complexity of the issue. Minor problems, such as replacing a faulty valve, fixing a leak, or resetting a component, can often be completed in just a couple of hours. More complex issues, like repairing a damaged heat exchanger, replacing internal components, or troubleshooting persistent pressure problems, may take longer. At Russell Haskins, we aim to provide efficient service wherever possible. During the repair, our Gas Safe registered engineers will carefully diagnose the problem, explain the required work, and complete it to the highest safety and quality standards, ensuring your heating and hot water are restored quickly and reliably.

At Russell Haskins, we provide transparent pricing so there are no surprises. We charge all boiler repairs by the hour, with the total cost depending on the complexity of the repair. In some cases, additional costs may apply if a replacement part is required and needs to be sourced or collected.

Most boiler issues can be repaired efficiently, especially when addressed promptly. Problems such as faulty valves, pressure issues, leaks, or ignition failures are often fixable without needing a full replacement. However, very old boilers or those with extensive internal damage may not be cost-effective to repair. In these cases, replacement could be the safer and more economical option, providing improved efficiency, reliability, and peace of mind.

When you contact us at Russell Haskins, our Gas Safe registered engineers will carefully assess your boiler, explain the available options, and recommend the best course of action, whether that’s a targeted repair or a full replacement, to ensure your heating and hot water remain safe, reliable, and efficient.

A leaking boiler is a serious issue that should never be ignored. Leaks can occur for several reasons, including:

• Worn or damaged seals inside the boiler

• Faulty pressure relief valves

• Corroded or loose pipework

• Internal component failure, such as a cracked heat exchanger

If you notice water around your boiler, switch it off immediately to prevent damage and call us to book a boiler repair. 

If your boiler pilot light keeps going out, it’s usually a sign of an underlying problem rather than just a minor nuisance. Common causes include:

• Thermocouple faults: the safety device that detects the pilot flame may be failing.

• Drafts: strong air currents near the boiler can blow out the flame.

• Dirty or clogged burner: debris can prevent the pilot from staying lit.

• Gas supply issues: low or inconsistent gas flow can cause the flame to extinguish.
  
  

Never attempt to bypass safety devices. Relighting the pilot yourself is possible on some boilers, but if it keeps going out, call us to book a boiler repair. We can safely diagnose and repair the issue, ensuring your boiler operates reliably and safely.

Preventing boiler breakdowns starts with regular care and attention. Scheduling annual servicing with a Gas Safe registered engineer ensures that your boiler is inspected, cleaned, and maintained, helping to catch potential issues before they become serious.

Simple routine checks, such as bleeding your radiators to remove trapped air, monitoring and maintaining the correct pressure, and keeping an eye out for leaks, strange noises, or error codes, can also help prevent problems. Addressing minor issues early, rather than waiting until they escalate, can save both time and money, while keeping your heating and hot water running reliably.
