Is an annual boiler service necessary?

If you’re a homeowner or a landlord, your home’s central heating boiler is an important appliance that pays closer attention. It can be frustrating when the boilers suddenly stop working, especially during cold winter months. Being without hot water and/or heating during the winter can be disruptive for any family.

That’s why it is extremely important to keep a regular check/maintenance on the functionality of your boiler. To do so, it’s vital you have your boiler serviced each year. An annual boiler service will flag up any early signs of trouble and nip them in the bud! In addition, you can get boiler insurance coverage depending on your requirement.

If you find your gas, electric or combi boiler isn’t producing sufficient heat and the water is tepid or cold, it’s a clear sign that there’s a fault which needs immediate attention. To avoid further complications, book a gas-safe registered engineer.

Fluctuations in the pressure of boilers are quite normal. However, if pressures remain low or high for long periods, it could mean something more serious is afoot, e.g., constant pressure loss could mean a concealed pipe leaking somewhere in the property.

Checking the flame colour is a simple process to determine if all is well with combustion. If the flame colour is clear blue, there’s nothing to worry about. However, if it’s turned yellow or orange, then it’s time to call serviceteam to check if any harmful gas such as CO (Carbon Monoxide) is present.

If the boiler constantly remains on after the correct temperature has been reached, there could be an issue with the thermostat or circulation due to debris in the radiators (sludge). These issues (and more) can be identified during an annual boiler service. If the above issues sound familiar, call serviceteam and get support for a diagnostic visit from one of our gas safe engineers.

You’ve probably got the message by now, and the importance of having your boiler serviced every year. If it’s not working properly, it could cost more to run or leak CO (carbon monoxide)!

If your boiler has been recently installed, the manufacturer will stipulate you have it serviced annually to validate the guarantee/warranty. If the boiler breaks down and the boiler’s service history record is not continuous, i.e., no evidence of it having been serviced every year, it could invalidate the manufacturer’s guarantee/warranty. This means funding the repair will be your responsibility!

Frequently Asked Questions

Make sure to call and get support from a professional boiler engineer who is in the heating and servicing business.

Q: Is boiler insurance a requirement?

Boiler insurance coverage can be a valuable consideration for homeowners and landlords. Deciding whether to purchase boiler insurance depends on individual circumstances and existing coverage options. Evaluating the monthly cost and assessing the suitability of the boiler cover is essential.

Different boiler types, such as combi, gas, electric, or smart boilers, may have specific insurance requirements. For example, Worcester Bosch and Baxi offer comprehensive insurance coverage for their boilers.

Worcester Boiler Insurance Cover provides round-the-clock access to qualified engineers, comprehensive parts and labor coverage, and reliable repairs.

Baxi Boiler Insurance Cover offers low-cost monthly fees, extensive coverage, 24/7 customer service, and a network of experienced engineers. Prioritizing boiler insurance ensures year-round comfort and peace of mind for your family.

Q: Do all types of boilers need to do annual servicing?

Yes. There are different types of boilers in the heating market. You may have gas boilers, combi boilers, smart boilers, or electric boilers from renowned brands such as Worcester Bosch, Viessmann, Baxi, Vaillant, etc. Yet you need to get your home boiler serviced every year, so we can help you find a qualified engineer to ensure you get the best and most cost-effective service. Never underestimate the consequences of boilers.

In order to keep everything operating as smoothly and safely as possible, boilers require regular maintenance. Servicing is more than simply a technique to repair boiler issues. By correctly caring for and maintaining your boiler, you can also avoid significant problems in the future.

Q: What is involved in fitting a new boiler?

Our gas-registered heating engineer will fit a new boiler in the same location or in another location, depending on your specific requirement. Any new location identified will probably mean more materials and time.

As the initial step of your boiler installation process, our engineer will cover nearby surfaces with carpet protectors and dust sheets to ensure that your space stays neat and tidy. Once the old boiler is separated from its gas and water supply lines, it is removed to make way for the new one – but not before any leftover debris inside is cleared out entirely! To get rid of the residue in the central heating system, we might resort to a chemical flush or, if necessary, even an intensive power flush over several hours. Afterwards, pipes may be reconfigured around the heater location (typically the boiler room), so you can benefit from minimised heat loss while ensuring connection to radiators, main supplies as well as other important outlets have all been taken care of.
