Commercial Boiler Servicing: How Much Does It Cost?

A commercial boiler can be expensive to install, but since it will likely last up to 15 years, it is certainly worth it.

Nevertheless, over the years you may encounter problems and need some minor repairs, and if you’re wondering what these repairs will cost you, you’re not alone.

Commercial boilers generally last 15 years, but if you’re having any problems during that time frame, it’s good to call in a technician to diagnose the problem.

Some common problems include:

• Noises coming from the boiler
• Hot or cold spots in your building
• Leaks
• Sudden increases in utility bills

The cost of boiler repairs can vary depending on factors such as the boiler’s age, your business location, and the specific issue.

For an average service call, you can expect to pay between £135 and £460. If your boiler is overdue for maintenance, contact us to schedule a service.

What Affects Repair Costs?

The price of repairs may change based on factors such as:

• Boiler Location: A hard-to-reach unit may increase labour costs.
• Parts Replacement: The number and type of parts replaced can influence the cost.
• Service Fees: Some companies have minimum service or hourly fees, which can be as high as £110 per hour.

Always ask for an estimate before repairs to avoid surprises. At Roma Heating, we’re transparent about costs and provide clear quotes before starting work

Fortunately, a reputable plumbing company should be able to give you at least a rough estimate before they come to your office.

Keep in mind that once they get there, the price may change. Things such as where the unit is located and how many parts they have to replace can change the cost of the service, though not always by a lot.

Many plumbing companies will have a minimum service or per-hour fee, and those fees can be as high as £110 per hour or even higher.

Check with the company and ask them what their specific fees are so you won’t be surprised when they get there.

Regular yearly maintenance of your commercial boiler is crucial to keeping it running properly year after year. Because of this, it’s good to know what a local company’s fees are, even if it is just an estimate.

When it comes to the low versus the high end prices, you can expect to pay as little as £70 or as much as £880 for that service visit.

This is a wide range, of course, so let’s take a look at some prices for some specific services.

Let’s take a look at some of the more common commercial boiler problems and what they may cost to repair:

• Mineral deposits: £7 to £29 for materials / £110 to £180 for labour
• Faulty circulator, ductwork, etc.: £110 to £255 for materials / £180 to £360 for labour
• Faulty expansion tank: £29 to £95 for materials / £75 to £180 for labour
• Faulty pipes, circulator, valves: £110 to £290 for materials / £145 to £430 for labour
• Ignitor switch: £18 to £110 for materials / £75 to £145 for labour

Of course, because prices can vary so much depending on lots of factors, you can always call a local company and ask what they charge for materials and labour for each specific project.

When Should You Replace a Boiler?

While boilers often last up to 15 years, replacement may be more cost-effective if:

• The boiler is more than 10 years old.
• You’re frequently repairing it, and the costs add up.
• A new boiler will offer improved energy efficiency.

Gas boilers cost between £1,800 and £5,600 on average, making replacement a better long-term investment in some cases.

Other problems with your boiler can include:

• No heat or poor heat production.
• Mineral deposits.

• A malfunctioning pilot or burner ignition.
• Problems with the water circulation pump.
• Issues related to the expansion tank.

This being said, keep in mind that there are a few different types of boilers, and each one has its own repair problems and costs.

Let’s take a look at the average repair costs and the most common problems with each type.

• Average repair costs of £145 to £360.
• Common problems include clogged burner nozzles, cracks in the heat exchanger, and fuel pipes that are corroded or clogged.

Yearly inspections are essential to ensure your boiler operates efficiently and safely. Technicians will:

• Test every part of the boiler
• Clean components as needed
• Inspect controls, valves, and gauges to identify potential issues
• Most inspections last an hour to 90 minutes, depending on the boiler.

Why regular inspections matter:

• Prevents minor issues from escalating into costly repairs
• Improves boiler efficiency, reducing energy costs
• Extends the lifespan of your boiler

In addition to catching problems before they become too complex or expensive to repair, regular inspections always enable the boiler to run more efficiently, saving you a lot of money on your monthly utility bill.

One thing you don’t want to do is try and ascertain any problems with the boiler yourself.

This can actually make things worse in the end.

The good news is, boilers are dependable and usually last up to 15 years with only annual inspections necessary to keep them running.

Repairs may be needed at times, but you can get an estimate of the costs beforehand so that your final bill isn’t such a surprise.

Some companies even have financing plans for those times when replacing the boiler is your best option.

They’ll work with you so the process isn’t complicated or difficult for you.
