Emergency Commercial Boiler Issues

Boiler breakdowns come in all forms and can happen for various reasons. Some are easy to diagnose, whereas some take a little bit longer. The most important thing is getting an engineer on site as quickly as possible, as minor problems can translate into costly, avoidable repairs further down the line.

Some Common Boiler Breakdowns Our Engineers Fix

Ignition Failure

If a boiler suffers from a gas or electricity supply issue, it will shut down to avoid a dangerous situation. The boiler will display an appropriate fault code, ready for our engineers to diagnose the problem and get your heating back up and running.

Low Pressure

The system has insufficient water if your boiler pressure is too low. Water loss can be traced to various causes but usually to a leak. With minimal downtime, we’ll get your pressure back up to where it needs to be.

Pump Failure

Poor heating, leaks, or strange noises could indicate that your pump might need replacing. The pump’s function is to circulate hot water around your business, and if broken, it can cause issues for the entire heating system.

Emergency Boiler Repair Service

Diagnosing, repairing, and testing boilers is crucial to ensuring their proper functioning and safety. So, what can you expect when an engineer attends a boiler emergency?

When we receive a call for a boiler repair, the first step is to gather essential information, such as the boiler’s make and model, the nature of the problem, and any unusual sounds or odours. Our maintenance team may provide initial instructions to ensure a safe environment. We’ll dispatch an engineer with the appropriate PPE and the necessary tools and equipment for the job as soon as possible. They’ll first conduct a visual inspection of the boiler and its surroundings and ensure the area is well-ventilated and free from any flammable materials or obstructions.

The engineer will examine the boiler’s components, check for error codes or warning lights, and listen for unusual noises. They may shut off the gas supply and electricity to the boiler before performing any diagnostics. With strict adherence to safety protocols, the engineer will proceed with the necessary repairs, ranging from simple fixes like replacing a faulty component to more complex tasks.

Once they complete the repairs, they’ll test the boiler’s functionality. The engineer will ensure that safety controls work correctly, such as pressure relief valves and temperature sensors. They’ll also check for gas leaks and carbon monoxide emissions. When it’s finished, we’ll summarise the work done, any further recommendations for maintenance or improvements, and documentation of the service provided.

Emergency Commercial Boiler Repairs FAQ

What long does it take to repair a boiler?

The amount of time it takes to repair a boiler depends on the severity of the breakdown. In most cases, it’s a couple of hours, but it can vary if new parts are needed. In any case, we’ll send an engineer to make the boiler safe as soon as we can after we hear from you.

What are some common causes of boiler breakdowns?

Ignition lockups, pressure issues, pump failures, PCB faults, and fan problems are all common examples of boiler breakdowns. Some will be easy to fix, and some will require further inspection. Our maintenance team will listen to your problems and promptly diagnose the cause of your boiler breakdown.

How can I prevent my boiler from breaking down?

Preventative maintenance is always better than reactive maintenance. The best way to prevent your boiler from breaking down is to ensure you have an effective maintenance plan in place. Regular boiler servicing helps save those minor problems from turning into costly repairs. Please be sure to find out more about our boiler servicing.

Can I still use my boiler if it’s making unusual noises?

Unusual noises are a tell-tale sign that something is wrong with your boiler, and it’s wise not to use it. Boilers can be hazardous appliances, and a professional must see them safely rather than trying to fix them yourself.

How long does it typically take for an engineer to arrive for an emergency repair?

Depending on where you are, it will typically take less than two hours to get an engineer on site. If your problem is severe and poses an immediate danger to your building and employees, we will prioritise our engineers’ schedule to get them to you as quickly as possible.

UES has developed a great understanding of our infrastructure. They react quickly, and their staff are highly knowledgeable. I have recommended them to several people.
