When it comes to your home heating, your boiler is at the heart of it all. At Wright Gas, we’ve helped thousands of customers across Glasgow, Paisley, and beyond with boiler maintenance, repairs, and new boiler replacements, and one thing we’ve learned is that most people have the same core questions.

In this comprehensive FAQ guide, we’ll walk you through the essentials of boiler servicing, when and why you should consider a boiler replacement, what affects boiler prices, and everything in between.

What is boiler servicing?

Boiler servicing is a routine inspection and maintenance check carried out by a Gas Safe registered engineer. It involves assessing the performance, safety, and efficiency of your boiler. Whether you have an older model or a modern Ariston boiler, servicing helps ensure everything is running as it should.

At Wright Gas, we offer both standard servicing and full strip down boiler services. The boiler strip down service includes thorough cleaning of internal components, checking the burner and heat exchanger, and inspecting for any early signs of wear. This type of detailed maintenance can extend the life of your boiler and improve efficiency.

Why is boiler servicing important?

Regular boiler servicing offers several key benefits:

• Safety: Detects potential hazards like gas leaks or carbon monoxide.
• Efficiency: Improves heating performance and reduces energy bills.
• Longevity: Prevents costly breakdowns and extends boiler life.
• Warranty Compliance: Required by manufacturers to keep warranties valid.

Skipping a service could mean your boiler becomes less efficient, more prone to issues, or even dangerous. For homeowners in Glasgow and surrounding areas, our boiler service and maintenance packages are tailored to keep your system running safely and smoothly all year round.

What are the signs that my boiler needs servicing?

If your boiler is acting up, it may be time for a service. Look out for:

• Noisy operation, whistling, banging, or clunking
• Radiators that heat unevenly or stay cold
• A boiler that cuts out randomly
• Water leaks or visible rust
• Yellow or irregular flame
• Unusual smells or increased condensation near the boiler
• Higher-than-normal heating bills
• Constant resetting or loss of pressure

Even if the boiler seems fine, an annual check is always recommended to catch issues early. Don’t wait for your boiler to stop working, prevention is better than a chilly surprise!

What happens during a boiler service?

A comprehensive boiler service typically includes:

• Visual Inspection: Checking the external condition, pipework, and flue system.
• Component Checks: Inspecting key parts like the burner, heat exchanger, fan, seals, ignition system and sensors.
• Internal Cleaning: In a full strip down boiler service, we clean soot, debris and scale from internal components.
• Gas Pressure & Flue Testing: Ensuring proper gas flow and safe exhaust.
• Efficiency Assessment: Checking combustion levels using flue gas analysers.
• System Checks: Testing controls, safety devices and thermostat performance.

Afterwards, you’ll receive a full service report. If anything needs attention, like a repair or potential boiler replacement, we’ll talk you through your options.

How long does a boiler service take?

A routine service usually takes 45 minutes to 1 hour, depending on your boiler’s make and condition. More complex models or older systems may take longer, especially if a strip down service is needed. We always aim to work efficiently, cleanly, and with as little disruption as possible.

How often should I have my boiler serviced?

Every 12 months is the industry standard. Annual servicing is recommended by all major boiler manufacturers, and failing to stick to this can invalidate your warranty, especially on new boiler replacements or premium models like Ariston boilers.

In our experience, a yearly service ensures optimal performance, prevents expensive breakdowns, and keeps your system in warranty. Our customers in Glasgow and Paisley often set a reminder to book in spring or summer, smart move!

What time of year should I get my boiler serviced?

The best time? Between spring and early autumn. That’s when demand is lower and you’re not relying heavily on your heating. It also gives you plenty of time to resolve any issues before winter sets in. Don’t wait for cold weather to uncover a boiler not working problem, book early and be prepared.

Do I need a boiler service to validate my warranty?

Yes, most warranties require annual servicing by a Gas Safe engineer to remain valid. If your boiler breaks down and you’ve skipped a service, you may have to cover the repair costs yourself.

This applies to many brands including Ariston boilers, and especially for recent gas boiler replacements. At Wright Gas, we keep detailed records of every service, which we’re happy to provide if your warranty is ever questioned.

Can I service my boiler myself?

We get asked this a lot, and the answer is always: absolutely not. Only a Gas Safe registered engineer is legally allowed to carry out boiler servicing or repairs. Attempting to do it yourself isn’t just dangerous, it can invalidate warranties and even break the law.
If you’re searching for “boiler installers near me” or need someone to maintain your system safely, go with a trusted local company like Wright Gas.

How often should I powerflush my system?

A powerflush is a deep-clean of your entire central heating system. It’s usually recommended every 5 to 7 years, or sooner if you notice:

• Radiators slow to heat
• Cold spots, especially at the bottom
• Dirty or sludgy water when bleeding radiators
• Noisy boiler or pipes

We often suggest a powerflush when doing a new boiler installation, especially if your system hasn’t been cleaned in years. It ensures clean water flows freely and your boiler runs more efficiently.

When should I replace my boiler?

Even the best-maintained boilers have a lifespan. Here’s when to consider a boiler replacement:

• It’s over 12–15 years old
• Repairs are becoming frequent and costly
• Your energy bills are rising
• It’s noisy or leaking
• Parts are hard to source
• It no longer meets current efficiency standards

If your system ticks any of these boxes, a gas boiler replacement could save you money in the long run. We offer expert guidance on boiler prices, boiler change cost, and the best systems to suit your home and budget. Whether you’re in need of a standard swap or a full boiler and installation package, our engineers will provide honest, jargon-free advice, and no pushy sales.

How much does a boiler service cost?

A typical boiler service in the UK costs between £70 and £120, but can be less or more, depending on your location, the type of boiler, and the depth of the service. A standard boiler service usually includes safety checks, cleaning, and basic performance tests. For a more thorough inspection, such as a full strip down boiler service, you can expect to pay between £100 and £130.

Regular servicing not only keeps your boiler running efficiently but can also prevent costly breakdowns and ensure your warranty remains valid.
