How Often Should I Get My Oil Boiler Checked?
Avoid Chilly Surprises and Keep Things Running Smoothly
If your home runs on an oil boiler, you already know how crucial it is—especially when the cold weather kicks in. But here’s the thing: oil boilers work hard all year long, and just like any hardworking appliance, they need a bit of care.
So how often should you get your oil boiler checked?
Once a year. No more, no less.
And here’s exactly why that annual service is a total no-brainer.

🧰 Spot Problems Before They Turn Into Payouts
A yearly check-up isn’t just about keeping things tidy. It’s your boiler’s best defence against surprise breakdowns, mid-winter disasters, and those awkward moments when your shower goes ice cold.
Servicing once a year means a qualified engineer can:
-
Catch worn parts before they break
-
Remove the build-up of soot and debris
-
Keep everything running safely and efficiently
Basically, it’s your chance to stay one step ahead—and avoid costly repairs down the line.
💸 Save on Repairs and Your Heating Bills
Let’s be real—no one enjoys unexpected expenses. But an oil boiler that hasn’t been checked in a while? That’s a repair bill just waiting to happen.
Routine servicing helps prevent:
-
Breakdowns at the worst possible time
-
Poor performance and wasted fuel
-
System wear and tear that shortens your boiler’s life
And here’s the kicker: a well-maintained oil boiler burns fuel more efficiently. So you use less oil and save more money. Simple.
🛡️ Protect Your Warranty Like a Pro
This one’s important. Most oil boiler manufacturers include a clause in the warranty requiring annual servicing. Miss it—and your warranty could be toast.
So even if your boiler’s still under guarantee, make sure you’re covered by booking a service every 12 months. That way, if something goes wrong, you won’t be stuck footing the bill.
♻️ Efficiency Is Everything
Let’s talk performance. Over time, oil boilers naturally become less efficient, especially if they’re not cleaned or tuned regularly. Soot build-up, blocked filters, and fuel residue all slow things down.
With annual maintenance, you get:
-
A cleaner, more powerful burn
-
Faster heating and hotter water
-
Lower fuel usage and fewer emissions
And honestly, who doesn’t want a warm home that costs less to run?
🛠️ What’s Included in an Oil Boiler Service?
Wondering what actually happens during a boiler check? It’s more thorough than you might think. Most standard services include:
-
Cleaning of heat exchangers, filters, and oil nozzles
-
Testing safety devices and system controls
-
Checking for leaks or early signs of damage
-
Verifying combustion levels and CO emissions
All in all, it takes around an hour—but the benefits last all year long.
⏰ When’s the Best Time to Book?
Aim to get your boiler serviced once a year, ideally in late summer or early autumn. This gives you plenty of time to fix any issues before winter rolls in.
Plus, engineers tend to be less busy during the warmer months, so you’ll have more flexibility when booking.
Pro tip: set a yearly calendar reminder so it never slips through the cracks.

✅ Catch problems early
