Homeowners Often Wonder: How Often Should a boiler be serviced?

Boiler servicing isn’t glamorous, but it’s one of the simplest and smartest ways to protect your heating system, reduce energy bills, and stay legally compliant as a landlord or homeowner.

If you’ve ever wondered ‘how often should a boiler be serviced?’, or what it even includes, this guide is for you. We’ll explain the benefits of regular boiler maintenance, how long it takes, what’s checked during a service, and why it’s best not to wait until something breaks.

So, how often should I service my boiler?

Every gas boiler should be serviced once a year, without fail.

That annual check isn’t just a box-ticking exercise. It’s vital for:

• Ensuring your boiler is running safely and efficiently
• Catching small faults before they become costly breakdowns
• Protecting your boiler warranty, which often depends on annual servicing
• Keeping energy bills down by preventing inefficiencies
• Ensuring proper combustion and checking for carbon monoxide risks

If you’re a landlord, an annual boiler service is a legal requirement. You’ll need to provide your tenants with a valid Gas Safety Certificate (CP12), and your gas appliances must be checked by a Gas Safe registered engineer.

Homeowners aren’t legally required to service their boilers, but ignoring them could cost you more than you think.

What does a boiler service include?

When you book a service with KD Jones Heating Engineers, your Gas Safe registered engineer will carry out a full inspection of the boiler and connected components.

Here’s what’s included:

• Visual inspection of the boiler and flue
• Checking gas pressure and flow
• Testing emissions and combustion
• Inspecting internal components
• Checking seals, valves, and safety devices
• Cleaning parts if needed
• Verifying hot water and central heating output
• Checking for leaks or corrosion
• Resetting controls and timers if required
• Logging all checks for compliance and warranty records

We don’t rush through it, either. A boiler service typically takes 45–60 minutes, depending on the model and condition.

What are the signs I’ve left it too long?

If your boiler:

• Takes longer than usual to heat your hot water
• Makes strange noises (gurgling, banging, whistling)
• Is using more gas than expected
• Keeps needing pressure top-ups
• Is over 12 months past its last service

…it’s probably time to book a service. Even if everything seems fine on the surface, hidden faults and slow efficiency loss can build up without warning.

Regular servicing ensures peace of mind, especially when winter hits and your heating engineer is booked solid with breakdown calls.

How much does a boiler service cost?

Costs vary depending on your location and boiler type, but most services fall between £80–£130. At KD Jones, we offer competitive rates with no surprise add-ons.
