Boiler Service: What You Need to Know

Regular boiler service keeps your home warm, saves on bills, and stops nasty breakdowns. Skipping it can mean costly repairs or a cold shower. Let’s walk through how often you should book a service, what’s covered, and how much you’ll likely pay in 2025.

How Often Should You Service Your Boiler?

Most manufacturers and insurers say once a year is the sweet spot. A yearly check catches wear before it blows up and keeps your warranty valid. If you use the boiler a lot – think multiple showers a day or a large family – you might want a service every six months. On the other hand, a brand‑new, low‑usage unit can sometimes stretch to 18 months, but set a reminder anyway.

What Does a Boiler Service Cover?

A qualified technician will:

  • Inspect the burner, heat exchanger, and flue for signs of corrosion or blockage.
  • Check gas pressure, safety valves, and the thermostat for correct operation.
  • Clean key components, removing limescale and dust that reduce efficiency.
  • Test the water pressure and flow rate, topping up if needed.
  • Run a safety check on the ventilation and carbon monoxide detector.

That’s the core of a standard service. Some companies also offer a full “boiler health check” that adds a detailed efficiency report and advice on future upgrades.

When you read our "Boiler Service Cost Guide 2025", you’ll see the average price sits between £80 and £150. Prices rise if you have a high‑efficiency condensing boiler, live in a hard‑water area, or need extra parts replaced. Ask for a breakdown so you know what you’re paying for.

DIY fixes are tempting, especially after reading "Can I Repair My Boiler Myself?" However, working with gas and pressurised water can be dangerous. You can safely clean the external pipework and replace the pressure relief valve, but anything involving the burner or gas line should be left to a Gas Safe registered engineer. If you ever smell gas, hear strange noises, or see leaks, shut the boiler off, ventilate the house, and call a professional immediately.

So, when should you call a pro? Anytime you notice these signs:

  • Unusual noises – banging, whistling, or clanking.
  • Fluctuating water temperature or a loss of heat.
  • Visible rust on the boiler body or pipes.
  • Repeated error codes on the display panel.
  • Any water pooling around the unit.

These clues often mean the boiler is nearing a breakdown. A quick service can fix small issues before they turn into expensive repairs or a full replacement. Our "Boiler Repair vs Replacement" article walks you through the cost comparison, so you can decide what makes sense for your budget.

Bottom line: book a yearly service, keep an eye on performance, and don’t gamble with DIY gas work. A well‑maintained boiler lasts longer, runs cheaper, and gives you peace of mind during those cold winter months.
