Can you remember the last time your boiler was professionally serviced? If it's been over 12 months, it's time to schedule your next check.

Annual Boiler Service Checks

An annual boiler service plays a crucial role in maintaining both performance and safety. During a typical visit, our qualified engineer will carry out a full inspection of your boiler’s key components, clean internal parts, check for wear or corrosion, and test for dangerous carbon monoxide emissions.

These routine checks help:

  • Maximise energy efficiency and reduce your running costs
  • Prevent the risk of carbon monoxide leaks
  • Extend the lifespan of your boiler
  • Maintain manufacturer warranties and insurance coverage

Even if your boiler seems to be working fine, hidden issues can develop over time, and a yearly service is the best way to catch them early.

What’s Included in a Boiler Service?

A boiler service is more than just a quick check, it’s a comprehensive process that ensures your heating system is running efficiently, safely, and in line with current standards. At Fixbot, we follow a structured and thorough approach on every service visit to give you peace of mind, extend the lifespan of your boiler, and maintain the conditions of any manufacturer warranty.

Visual Inspection of the Entire System

Our engineer will begin by visually inspecting the boiler and surrounding pipework to check for signs of wear, leaks, corrosion, or damage. This includes looking for any water stains, rust, or indicators of stress on internal components, which could lead to future issues if left unaddressed.

Safety Checks Including Ventilation and Flue Analysis

We ensure your boiler has proper ventilation and that the flue is correctly fitted, securely positioned, and unobstructed. A detailed flue gas analysis is performed to check emissions and combustion levels, confirming that your boiler is burning fuel safely and efficiently.

Cleaning of Key Components

Critical internal parts such as the burner, heat exchanger, and fan will be cleaned to remove any soot, dirt, or residue build-up. This cleaning process not only improves energy efficiency but also prevents potential faults caused by blocked or dirty components.

Gas Pressure and Flow Rate Testing

We test the gas pressure at various points in the system to ensure it meets manufacturer specifications. If the pressure is too low or too high, your boiler’s performance can suffer and in some cases, it may even shut down. Proper flow ensures your boiler can consistently heat your home and hot water.

Carbon Monoxide Checks

Using specialist equipment, we check for any carbon monoxide emissions and ensure the boiler is not releasing dangerous gases into your property. This is an important step for your family’s safety, as carbon monoxide is odourless and potentially lethal if undetected.

Verification of Boiler Controls and Seals

All safety devices, thermostats, and boiler controls are tested to ensure they’re working properly. We’ll also inspect door seals, casing, and joints for any signs of damage or looseness, helping to prevent issues like water leaks or air ingress.

Advice on Improving Energy Efficiency

If we identify ways you can improve the efficiency of your heating system, such as adjusting settings, updating insulation, or scheduling radiator balancing, we’ll let you know. Even small changes can make a noticeable difference to your heating bills and comfort levels.

Every Fixbot engineer is Gas Safe registered and receives ongoing training to stay up to date with current regulations and best practices. Whether you're using a Viessmann system or another boiler brand, we carry out every service to the highest standards, with safety at the heart of what we do.
