Boiler servicing is often one of those boring but dutiful tasks we tell ourselves we need to do periodically, but a surprising number of myths abound about what exactly servicing comprises—many, it turns out upon inspection, are inaccurate, either because of our lack of technical knowledge about how it all works or, far more often, because we perpetuate them out of sheer inertia. From a failed warranty to a missed problem, or the absence of what would have been a timely alert, these myths can cost the homeowner something both tangible and intangible. We will dispel ten common boiler servicing myths, explore where they came from, and describe what a qualified professional actually does during each boiler service Bristol visit. While we are not a substitute for a qualified engineer, knowing what they should and actually do entails will be beneficial for all owners, especially newer residents or those who are already in a Bristol home with a previous ownership and a potentially bewildering plumbing layout.

Myth Servicing Is Only About Passing a Safety Check

The boiler service is perceived by many to be a pass or fail in terms of whether the machine is safe to use. Although the safety of a boiler must indeed be assessed, a full service involves more than just the simple checks that lead to the appliance receiving a clean bill of health. In addition to the basic safety aspects, an efficient service will check the operation and performance of the appliance, monitoring the gas flow and pressure, inspecting seals and joints for signs of wear and tear and also ensuring that devices like the timer and programmer etc operate correctly.

These operational aspects can detect impending issues at a very early stage before the appliance’s functionality or its very safety are compromised – to view servicing solely in these terms greatly reduces the benefits.

A boiler can pass a safety test yet, in practice be underperforming – this kind of problem will be identified through a service carried out correctly. Understanding these aspects will invariably lead you to ask a more searching question of your boiler service provider and the subsequent report.

Myth A New Boiler Does Not Need Servicing

While it might make sense to assume that a sparkling new appliance requires next to no maintenance in its initial few years of use, this perspective fails to appreciate how inextricably linked most manufacturer warranties are to annual serving, irrespective of how young your boiler is. An omission to have the boiler serviced in its first year following installation is just as likely to render the manufacturers’ warranty invalid as an omission in year ten. This is not a reflection on whether or not a boiler is likely to have acquired a fault worthy of warranty repair by the age of one, but as to whether there are issues with the installation or manufacturing that need identification within the first year rather than beyond the warranty window, for once that is closed, things become much more expensive to repair irrespective of age. Making the assumption that there is no need to service a new boiler because it “feels new” is indeed an exceedingly expensive assumption for the boiler-owning household to make!

Myth Any Handyman Can Service a Gas Boiler

It is against the law to have your gas boiler serviced by anyone other than someone who is Gas Safe registered. This isn’t just because the gas industry require it to be up to standard; gas safe registration is actually a legal requirement as part of Gas Safe rules. The result of you using someone who is not on the Register (no matter how competent he might be when it comes to fixing a tap, or changing a door lock!)

would leave you seriously at risk, not to say invalidate your boiler warranty.

Using any trades person you call on for help is something that a homeowner becomes accustomed to. However, boiler servicing falls into a separate category to other home repairs, and a quick check online with a tradesman’s gas safe id card will take you only a few moments and afford peace of mind that they have the right skills and accreditations.

Myth Skipping One Year Makes No Real Difference

That one year’s skipped servicing may only be overlooked (especially if the boiler carries on working happily as if all is well!) but it is possible to be the source of bigger problems down the line. If your new boiler has a manufacturer’s warranty then most stipulate having an uninterrupted record of annual servicing, and a gap in this is usually enough to void the whole thing, regardless of what went before.

However, one year means two years before it is next looked at so there is twice the chance of problems, even minor ones, to develop to being something much bigger.

Many homeowners mistakenly think that as long as they get up to date with servicing by next year then that history of servicing will start again but most manufacturers use the gap as absolute and then there’s nothing for it.

Myth Landlords Only Need a Certificate Not a Full Service

An annual gas safety check must be arranged by the landlord, and a certificate handed to the tenant. Some owners of properties seem to think that completing this legal requirement is the same as carrying out a full service to the boiler. The gas safety certificate is concerned with nothing more than a check to make sure that the equipment meets safety standards and is not posing any dangers, whereas a full service will investigate how the boiler is performing overall and help keep it working in good order to prolong its life and cut down the chance of breakdowns affecting any tenants.

Engineers can be instructed to carry out both a service and check for safety and an extra visit to the premises does not add any more significant time to an already booked visit from an engineer but can provide the owner with a clearer picture of how the boiler is working.

A combined check like this can save money too as the engineer is already at the property and familiar. Owners may discover that if only a safety certificate is arranged, repairs are always becoming necessary on the boiler and are happening more often than with owners who take both visit carried out at the same time.

Myth A Working Boiler Does Not Need Checking

It may seem tempting to think that if the boiler is heating the house and supplying hot water without any trouble, there is nothing to be done, but a great number of developing problems won’t be apparent to somebody without specialised training. The boiler may not be burning fuel efficiently, may be operating at reduced pressure, or may simply be suffering from subtle wear and tear of an internal part, yet may still appear to be working normally to an ordinary householder. CO leaking, for instance, could be occurring through the system without any appreciable difference to the boiler’s operation. This is why arranging a regular boiler service Bristol homeowners can rely on is important for identifying potential issues before they become more serious.

This is why annual service checks by a Gas Engineer.

If waiting until it stops working before asking for a service, one is missing the whole idea of scheduled maintenance!

Myth Servicing Always Costs the Same Everywhere

As always there’s a massive difference in boiler service prices from company to company in Bristol, so just assuming the same rate applies will either overpay, or end up accepting a price because “it was so cheap” without asking what’s actually covered. The biggest thing that’s not a standard across the city, that determines price, is the type and age of boiler you have, or if things like a quick power flush and a pressure test are thrown in for free. Some companies charge the same price regardless of the type of unit in question, others vary the amount it cost depending on how complex the plumbing is that’s attached to the boiler you own.

I expect it’s possible there are small variations in price within the city dependent on geography as well although again some covering a wider area include travel time costs to further bits of the city, some take nothing.

Just get half a dozen quotes, and ask explicitly what” the standard boiler service” covers.

Myth The Cheapest Service Offer Is Just as Thorough

While we often notice a bargain price for many of things we use daily for servicing our boiler is certainly a major one and that bargain might be very tempting to those seeking an investment and not something they view as more than a necessary evil, the fact is lower price may not get you the same length visit to servicing or the same extent of boiler testing. Some of these cut price service deals only include the bare legal and essential safety testing but do not extend to full performance testing and testing of all functional components that a full service would include so underlying faults could be missed leading them to be much more of a serious problem some 12 to 15 months down the road and in no way would a cheaper deal be cost-effective in the long term. Therefore, by not so subtly questioning as to exactly what you’re getting with one of these ultra-bargain deals and looking closer to one you find in any established local boiler servicing and maintenance company, could even be a lot more Cost-Effective in the long term to pay that little extra.

Myth Servicing Guarantees No Future Breakdowns

Yes the extensive checks performed during your boiler’s annual service will massively reduce the risk of a sudden breakdown but it cannot fully prevent all possible problems and in some cases, especially on an old boiler, a part can suddenly break down in between your boiler services because that particular part is coming to the end of it’s serviceable life despite any amount of maintenance your boiler may have had in its history. A boiler’s yearly checkup is designed to manage your risks and catch any possible problems with your heating systems, it’s not supposed to be a guaranteed system that will work trouble free for a full year after the checkover, a boiler engineer can only check it out at the time, and a working boiler part which passed your boiler’s checkover may suddenly give way weeks down the line after developing wear that the engineer wasn’t capable of checking at the time of your annual service checkover. Some may feel the blame lies with the engineer if you happen to suffer a breakdown with your boiler soon after a annual visit but that really should not be the case as even a properly serviced boiler can develop and breakdown.

Myth Once Serviced a Boiler Needs No Attention All Year

An annual service is an important part of boiler care, but it is not intended to replace the small ongoing checks a homeowner can reasonably carry out between visits. Keeping an eye on the pressure gauge, listening for any new or unusual noises, and noticing changes in how quickly rooms heat up are all things worth paying attention to throughout the year rather than only during the annual visit. Treating the service as a single yearly event that covers everything can mean a developing issue goes unnoticed for months before it is finally caught at the next scheduled appointment. Combining a thorough annual service with a small amount of ongoing attention throughout the rest of the year tends to give the most reliable results and the best chance of catching a problem early.
