A gas boiler is a vital part of your home or business, providing necessary warmth and hot water to ensure comfort throughout the year. However, like any other appliance, your boiler requires regular care and attention to ensure it remains efficient, safe, and reliable. Boiler servicing is an essential part of this maintenance, but many homeowners and businesses in Gloucester may wonder how often a boiler should be serviced and what consequences they may face if they neglect this important task.
In this guide, we’ll address these key questions and provide expert advice tailored specifically to Gloucester residents. We’ll cover the importance of regular servicing, signs that your boiler might need a service sooner than expected, and the benefits of keeping your boiler in top shape. Additionally, we’ll highlight the expertise of Hewer as your trusted local facilities management company for all your boiler servicing needs.
How Often Should You Service Your Boiler?

The general recommendation for boiler servicing is once a year. This is the ideal frequency to ensure your boiler continues to operate safely and efficiently. Annual servicing is crucial for preventing unexpected breakdowns, ensuring safety, and prolonging the lifespan of your appliance.
Legal & Warranty Requirements
For landlords in Gloucester, regular boiler servicing is not just recommended—it is a legal requirement. Under the Gas Safety (Installation and Use) Regulations 1998, landlords must have their gas boilers inspected and serviced annually. This is to ensure the safety of tenants and compliance with health & safety regulations.
Furthermore, many boiler manufacturers require annual servicing to maintain the validity of your warranty. If you fail to have your boiler serviced regularly, you risk voiding the warranty, leaving you responsible for any repair costs that might arise.
Signs You Need a Boiler Service Sooner
While yearly servicing is the recommended minimum, some signs might indicate that your boiler needs a service before the next scheduled check. Look out for:
- Inconsistent heating or hot water: If your radiators are cold or your hot water flow seems irregular, this could signal an issue that needs attention.
- Strange noises: Whistling, banging, or gurgling sounds from your boiler could indicate a build-up of debris or a system fault.
- Higher-than-usual energy bills: If your heating costs suddenly spike, your boiler might not be running as efficiently as it should.
- Pilot light issues: If the pilot light frequently goes out or changes colour, it’s a sign that the combustion process may be faulty.
Benefits of Regular Boiler Servicing

Investing in annual boiler servicing brings several important benefits, both in terms of safety and cost savings.
Prevents Unexpected Breakdowns & Costly Repairs
Regular servicing helps identify and fix small issues before they become major problems. A minor fault caught early can save you from a costly and inconvenient breakdown, which could leave you without heating or hot water, especially in the colder months. A professional service ensures that your boiler is operating at its best and avoids any sudden failures that could leave you scrambling for repairs.
Improves Energy Efficiency & Lowers Bills
A well-maintained boiler is much more energy-efficient. Regular servicing ensures that your boiler is operating at peak performance, which reduces energy consumption and lowers your utility bills. As your boiler runs more efficiently, it uses less gas to heat your home or business, reducing your carbon footprint and saving you money.
Ensures Safety & Reduces Carbon Monoxide Risk
One of the most important reasons to have your boiler serviced annually is safety. Regular servicing checks for dangerous issues such as gas leaks, faulty components, or carbon monoxide emissions. Carbon monoxide is a colourless, odourless gas that can be lethal if undetected. Boiler servicing ensures that your system is running safely, protecting your family or employees from potential harm.
Extends Boiler Lifespan
Routine maintenance helps extend the lifespan of your boiler. By keeping all parts in good condition and addressing minor issues promptly, your boiler can continue to operate smoothly for many years, delaying the need for an expensive replacement.
How Much Does Boiler Servicing Cost in Gloucester?
The cost of boiler servicing in Gloucester can vary depending on several factors, such as the type of boiler you have and the company you hire. Typically, boiler servicing in Gloucester costs between £60 and £120. However, the price may vary slightly based on the specific service provider and the complexity of the service required.
Factors Affecting Cost
- Boiler Type: Different types of boilers (combi, system or conventional) require different levels of servicing and parts. For instance, a combi boiler may require a slightly higher service fee due to its complexity.
- Service Provider Reputation: Trusted companies with established reputations may charge slightly higher fees, but they offer the peace of mind that comes with quality service and Gas Safe certification.
- Additional Repairs: If your engineer finds any worn-out parts that need replacing during the service, you can expect additional charges for the repairs or part replacements.
Why Cheap Services Can Be Risky
While it might be tempting to opt for a cheap service, this can be a risk. Some low-cost providers may cut corners by using subpar parts or not following the correct procedures. In the worst case, a non-Gas Safe registered engineer could leave your boiler in an unsafe state. Always ensure the company you choose is Gas Safe certified. Hewer is fully accredited, providing you with peace of mind that your boiler is in safe hands. Learn more about our Gas Safe registration here.
