Why Should You Get Your Boiler Serviced?
Annual boiler servicing is vital for several key reasons, ensuring your home stays warm, safe, and energy-efficient throughout the year.
Here are some of the most important benefits of getting your boiler serviced annually:
- Ensures Safety
One of the most critical reasons to have your boiler serviced. Boilers that aren’t properly maintained can develop faults that lead to dangerous issues, such as carbon monoxide leaks. Carbon monoxide is a colourless, odourless gas that can be deadly, and a boiler service includes checks for leaks or other safety hazards. Especially in households with young children, the elderly, or vulnerable individuals, ensuring the boiler is safe should be a top priority.
- Improves Boiler Efficiency
A regularly serviced boiler will run more efficiently. Over time, components can wear out or become clogged with dust and debris. This means the boiler could have to work harder to produce the same amount of heat. An inefficient boiler consumes more energy, leading to higher energy bills. Boiler servicing means components are checked and keeps your boiler working at peak efficiency, saving you money on your energy bills.
- Prevents Breakdowns
Boilers are most likely to break down during the winter when they’re working the hardest. Couple with this with an inefficient boiler that is having to work harder than normal and you’re in for a disaster. Components will be working harder and therefore under more stress which could lead to breakdowns. Regular servicing helps identify small issues before they turn into costly repairs or, worse, a full breakdown when you need your heating the most. Fixing minor problems during a service can prevent inconvenient and expensive emergencies.
- Validates Your Warranty
Many new boiler are fitted with a warranty BUT with most manufacturers the boiler service is only covered if you have regular services by a qualified engineer. Failing to do so could mean that any future repairs or replacements aren’t covered, leaving you with hefty bills. A service record ensures that you can claim on your warranty if needed.
Keeping your boiler serviced means you can enjoy the peace of mind that your heating system is safe, efficient, and reliable.
What Is Included in a Boiler Service?
A boiler service will change from provider to provider as different companies/engineers may have a slightly different process but as a general overview here’s what a standard boiler service should include. A qualified Gas Safe registered engineer will carry out a series of checks and tests to identify any potential problems and to ensure optimal performance.
- Visual Inspection
The engineer will first visually inspect the boiler and surrounding area to check for any obvious signs of wear, leaks, or damage. They will also ensure that your boiler is installed correctly and adheres to current gas and electrical safety standards.
This initial check helps catch any visible issues that could affect performance or safety.
- Internal Component Inspection
Next the engineer should open the boiler to inspect the internal components, like the heat exchanger, burner, and fan. These will be thoroughly inspected for signs of damage, wear, or corrosion. The engineer will ensure that these parts are in good working order and replace any components if necessary.
A clean and well-maintained internal system helps prevent breakdowns and increases efficiency.
- Flue and Combustion Check
The flue removes harmful gases like carbon monoxide from the boiler. During the service, the engineer will check the flue to ensure it’s not blocked and that it’s venting gases outside as it should, safely. The combustion process will also be tested to ensure that the boiler is burning fuel efficiently and safely, minimising the risk of gas leaks.
- Pressure and Flow Tests
The boiler’s water pressure and flow rate will be tested to ensure the system is operating at optimal levels. Low pressure can result in poor heating performance, while high pressure can put unnecessary strain on the system – see our guide to boiler pressure for more information on this. The engineer will check for any issues and adjust the pressure as needed to ensure consistent heating and hot water supply.
- Cleaning
Over time, soot and debris can build up inside the boiler, particularly around the heat exchanger and burner. If required these areas will be cleaned to improve the boiler’s efficiency and performance. Removing this build up helps the boiler run smoothly and reduces the risk of parts becoming clogged and/or damaged.
- Safety Checks
Finally, the engineer will carry out a series of safety checks, including testing the boiler’s safety devices like the pressure relief valve and ensuring all controls are functioning properly. This ensures that your boiler can safely handle variations in pressure and that it shuts down correctly in case of any malfunction.
Once all the checks have been completed and the boiler has passed then a gas safe certificate will be issued.
What is the Approximate Cost of a Boiler Service?
The cost of a boiler service can vary across the UK and can depend on several factors, such as the type of boiler, your location, and whether you opt for a one-off service or a maintenance plan. Below is a breakdown of what you can expect to pay for a boiler service.
Typical Service Costs
With Huttie, a one-off gas boiler service costs £99 + VAT. This price includes a full inspection, cleaning, and safety checks by a qualified Gas Safe registered engineer.
Prices may be slightly higher if your boiler runs off an alternative heat-source, such as oil, but please enquire now and we will be glad to provide a price based on your needs.
Factors That Affect Boiler Service Cost
- Type of Boiler: The cost may vary depending on the type of boiler you have (combi, system, or regular). Combi boilers, for example, tend to be more straightforward to service, while system or regular boilers with separate hot water cylinders may take longer, potentially increasing the price.
- Location: The price of a boiler service can differ based on your location. Services in major cities like London tend to be more expensive than in smaller towns or rural areas.
- Boiler Age: Older boilers may require more attention during servicing, potentially increasing the cost if additional repairs or replacements are needed.
Boiler Service Plan Costs
Some homeowners prefer to sign up for a boiler service plan, which involves paying a monthly fee to cover annual services and maintenance whilst also including emergency call-out cover for your household. With Huttie, our plans typically cost between £15 and £30 per month depending on your needs. They offer peace of mind by spreading the cost over the year and ensuring your boiler and household is covered for unexpected issues.
Emergency Call-Outs
If you do not get your boiler serviced regularly and need an emergency boiler repair, the costs can be significantly higher, sprawling into potentially hundreds of pounds for repairs. Regular servicing helps avoid these unexpected costs and keeps your boiler in good condition year-round.
Tips & Tricks to Help Reduce Boiler Servicing Costs/Repairs
Here are some practical tips to help you save money and avoid unnecessary expenses:
Choose a Boiler Service Plan – Consider signing up for a boiler service plan, which typically includes an annual service and covers unexpected repairs. These plans allow you to spread the cost over the year and sometimes even include emergency call-outs, which can help you avoid hefty one-off repair fees.
Book A Service During the Off-Peak Season – Most homeowners book boiler services in the autumn or winter, just before or during the peak heating season. To save money, try to book your service in the spring or summer.
Compare Prices – Before booking a boiler service, get quotes from multiple local engineers or companies. Shopping around can help you find the most competitive rate.
Perform Simple DIY Maintenance – Carrying out basic maintenance tasks between annual services can help prevent bigger issues and reduce repair costs. For example, bleeding radiators to release trapped air, checking for leaks, and keeping the area around your boiler clean. NEVER touch any of the gas parts of the boiler unless qualified.
Check for Boiler Grants or Schemes – The UK government occasionally offers boiler grants or energy efficiency schemes such as The boiler upgrade scheme, particularly for those with inefficient, older boilers. Check to see if you’re eligible for a new boiler.
