Boiler maintenance for first-time buyers
Becoming a first-time homeowner is exciting, but it also comes with new responsibilities. Regular boiler maintenance helps to keep your home safe, warm, and energy-efficient while avoiding costly breakdowns.
Why boiler maintenance matters
Looking after your boiler and doing regular checks can help it perform more efficiently, which means it uses less energy to heat your home. This not only helps control your household bills but also reduces your impact on the environment. Regular servicing also ensures key safety systems of your boiler are functioning properly, helping to protect against gas leaks and carbon monoxide exposure.
For many first-time buyers, peace of mind is another benefit. Knowing your boiler has been checked by a Gas Safe Registered engineer and serviced each year removes uncertainty when winter arrives. You can feel confident your heating will work when you need it most.
Here are a few key reasons why regular boiler maintenance matters:
1
Safety
Routine servicing ensures your boiler operates safely and helps detect any issues such as gas leaks or carbon monoxide risks (In gas boilers) before they become dangerous.
2
Efficiency
A clean, well-maintained boiler uses less energy, helping to reduce running costs and your carbon footprint.
3
Reliability
Regular checks help prevent unexpected breakdowns in the middle of winter when you need heating the most.
4
Warranty protection
Most manufacturers, including Vaillant, require an annual service to keep your warranty valid.
5
Longevity
Preventive care extends your boiler’s lifespan and helps it perform at its best for years to come.

What’s included in a boiler service?
A boiler service and repair is more than just a quick check. It’s a detailed inspection and cleaning process carried out by a qualified engineer. Vaillant’s trained service engineers are specialists in boiler maintenance and know exactly what to look for to keep your boiler running at its best.
During a service, the engineer will inspect and test all major components, ensuring that your system is safe and performing efficiently. They’ll also clean internal parts, check the flue for obstructions, check any signs of wear or potential issues, and repairs can be arranged if needed.
Once complete, your engineer will provide a service record. Keeping this document safe is important, as it proves your boiler has been properly maintained and keeps your warranty valid. Vaillant engineers also use genuine parts, ensuring continued reliability and efficiency.
How often to service your boiler
As experts in boilers and heating systems, we generally recommend that every boiler be serviced once a year (even if it appears to be working fine). A yearly inspection gives your engineer the opportunity to catch any potential issues early, before they affect your heating or lead to a costly repair.
If you’ve recently bought a home, it’s a good idea to book a service as soon as possible, particularly if the previous owner didn’t provide recent service records. After that, make your annual service part of your home maintenance routine, ideally in summer or early autumn before the cold season starts.

Simple checks you can do yourself
While annual servicing must always be done by a professional, there are a few simple checks you can perform yourself between visits. These small steps can help you spot problems early and keep your heating system working smoothly.
Start by monitoring your boiler’s digital pressure gauge. The pressure should usually sit between 1.0 and 1.5 bar when the system is cold. If it drops below this range, your boiler may need topping up. Check your user manual for instructions or ask your engineer to show you how during their next visit. Or, if you have the ecoTEC plus boiler in your new home, watch our helpful video here on how to repressurise it.
Bleeding your radiators occasionally can also help. You can read our full radiator bleeding guide for detailed steps on this. If you notice cold spots at the top, it means air is trapped inside, making your heating less efficient. Bleeding radiators releases the air trapped, helping your system warm up more evenly.
You should also:
-
Listen for unfamiliar noises, which may suggest trapped air or debris.
-
Keep the area around your boiler tidy to ensure good ventilation.
-
Check that your flue outlet is clear of leaves, snow, or debris.
-
Inspect visible pipework for signs of rust, drips, or leaks.
For first-time buyers, boiler maintenance is one of the simplest ways to protect your comfort and your investment. A well-maintained boiler keeps your home warm, reduces running costs, and ensures you’re never left without heating when you need it most.

Does a boiler service cover repairs?
A boiler service does not typically include major repairs or parts replacement unless a fault has been identified. In this case, your engineer will break down the relevant repair costs once assessed. You can also book a boiler repair via myVaillant Web.

How long can a well-maintained boiler last?
With good maintenance, a boiler can last 12–15 years or more. But many factors (usage, water quality, installation, parts quality) can affect your boiler's lifespan.

What if the previous homeowner did not service the boiler?
You should get a service soon after moving in, check for faults, and start your own maintenance history. This can help prevent any sudden breakdowns, especially in colder months.
