Reduced Efficiency

When a boiler goes without servicing for five years, it’s unable to operate at its full capacity, leading to higher energy bills and a shorter lifespan. A poorly maintained boiler may struggle to provide sufficient heat and hot water for your home, causing your energy bills to soar.

The longer you wait to service your boiler, the more money you’ll end up spending on utility bills and potential repairs. In the long run, regular boiler servicing will save you money and ensure your home stays warm and cozy.

Safety Hazards

The lack of servicing a boiler for five years could lead to a buildup of dust, dirt, and debris, increasing the risk of leaks and carbon monoxide poisoning. Carbon monoxide is an odorless, colorless gas that can be hazardous, potentially leading to sickness and even death.

Having your boiler serviced annually by a Gas Safe registered engineer ensures it is operating safely and efficiently, giving you peace of mind and protecting your family from potential dangers.

Voided Warranty

A boiler that hasn’t been serviced regularly may have its warranty voided, leaving you responsible for any repairs or replacements that may be necessary due to defects or malfunctions. Manufacturers and service providers require annual boiler servicing to ensure the appliance is working efficiently and safely, making it a crucial aspect of keeping your warranty valid.

By neglecting your boiler’s maintenance, you could be putting yourself at risk of facing costly repairs without the support of a valid warranty.
