How often should your boiler be serviced?
As a homeowner, you’re likely aware that your boiler needs regular servicing. But if you’re wondering, “How often should my boiler be serviced?rdquo; we’ve got the answer for you.
Your boiler should be serviced at least once a year to ensure it’s working efficiently and to prevent any potential water or gas leaks. Skipping your annual boiler service can affect its performance, possibly lead to a breakdown, or even void your warranty.
When should you service your boiler?
Now that you know how often to service your boiler, the next question is: when exactly should you schedule a service?
Here are some situations when you should consider getting your boiler serviced:
- It’s been 12 months since your last boiler service Keep track of your last service date and schedule your next one within the following 12 months to ensure your boiler remains in top condition.
- You’ve recently moved If you’ve just moved in and don’t have a service record from the previous owner, it’s best to play it safe and have your boiler serviced as soon as possible. Then, make a note of the date to schedule your annual service each year from then.
- Your boiler’s performance is deteriorating Even if you’ve kept up with your annual services, you might notice your heating system acting up—such as water not getting hot enough, potential gas leaks, or rising energy bills. If your boiler is becoming less efficient, it’s time for a service to identify and fix any issues.
- Service your boiler in the summer Boilers tend to work harder during the winter months, so we recommend scheduling your service in the summer. By having your boiler serviced before the cold weather arrives, you can ensure it’s in good working order for the winter ahead.
Who should service your boiler?
Whether you have a gas, oil, or LPG boiler, it’s essential to have a qualified heating engineer service it annually. The specific qualification required depends on the type of boiler you have.
Before the engineer starts work, always verify their credentials by checking their ID to ensure they are qualified.
- Gas boilers A Gas Safe Registered engineer must be appointed to work on a gas boiler.
- Oil boilers For oil boilers, you’ll need an OFTEC (Oil Firing Technical Association) registered engineer.
- Never miss a service With an Advanced Plumbing and Heating Home Cover plan, we’ll arrange your annual boiler service for you, so you never miss a check-up.
Why do you need to service your boiler?
During winter, your boiler works hard to heat your home and provide hot water. Since boilers have many components, regular servicing is essential to keep everything running smoothly.
Here’s why you should service your boiler regularly:
- Safety first Gas leaks and carbon monoxide poisoning are rare, but having your boiler serviced regularly ensures you’re doing everything you can to protect your home and family.
- Boost efficiency A well-serviced boiler operates more efficiently, saving you money on energy bills and reducing the wear on your system.
- Catch problems early An annual service allows the engineer to identify small issues before they turn into expensive repairs.
- Reduce the likelihood of breakdowns Regular checks and maintenance help prevent complete boiler failures and the inconvenience of being without heat or hot water.
- Maintain your warranty If your boiler is under warranty, an annual service is typically a requirement to keep the warranty valid. Failing to service it could mean paying out-of-pocket for repairs that would otherwise be covered.
What does a boiler service involve?
Your annual boiler service typically takes between 30 minutes and 2 hours, depending on how thorough the inspection and cleaning need to be. Here’s what’s involved:
- The engineer will inspect the boiler unit and surrounding area, checking for any leaks, corrosion, or loose parts.
- They will follow the manufacturer’s service guidelines to ensure the appliance is operating safely. This includes combustion analysis and checking key components like the condensate trap.
- Some components, such as the combustion chamber and filters, may be cleaned to ensure proper operation.
- Before finishing, the engineer will conduct safety checks and fill out necessary paperwork, including gas safety forms.
Note: This is a general outline, and the process may vary based on the age of the boiler and the presence of any issues.
How much does a boiler service cost?
The cost of a boiler service can vary depending on factors like:
- The type of boiler
- The fuel your boiler uses
- Rates charged by the servicing company
- Accessibility of the boiler
- The brand and model of your boiler
- Your location
On average, boiler services cost between £60 and £150, with £75 being the typical price in the UK.
