What Happens If You Skip Your Yearly Boiler Service? December 04, 2025 Your annual boiler service is one of the simplest ways to keep your heating system safe, efficient and reliable. Yet many homeowners put it off, especially when the boiler seems to be working fine. Skipping your yearly service can lead to a range of costly and sometimes dangerous issues that often go unnoticed until the boiler breaks down. Reduced Efficiency and Higher Energy Bills Over time, boilers naturally accumulate dust, debris and worn components that affect performance. During a yearly service, an engineer checks and cleans key parts so the boiler can run smoothly. Without this, the system may use more fuel to produce the same amount of heat, which leads to noticeably higher energy bills. A boiler that is not looked after will also age faster, increasing the likelihood of expensive repairs later on. Increased Risk of Breakdowns Small faults often go unnoticed until they become major problems. A yearly service helps identify issues early, such as worn seals, low pressure or faulty sensors. If you skip this check, these faults can worsen and cause sudden breakdowns, often during colder months when the boiler is working harder. Emergency callouts and replacement parts can be far more expensive than routine servicing. Safety Concerns and Carbon Monoxide Risks One of the most important reasons for regular servicing is safety. A poorly maintained boiler can develop dangerous issues, such as incomplete combustion or blocked flues, which can increase the risk of carbon monoxide leaks. This gas is odourless and can be life threatening if not detected early. Annual servicing ensures all safety controls and ventilation points are working properly, keeping your home safe. Could Skipping a Service Affect Warranty or Insurance? Many boiler manufacturers require annual servicing to keep the warranty valid. If the service record is missing, you may not be covered if the boiler fails. Some home insurance policies also expect proof of regular maintenance. Skipping a service could mean facing unexpected costs without the support of warranty cover.
