The Dangers of DIY Boiler Repairs and Why You Should Always Leave It to the Professionals

Who Can Install a Gas Boiler?

It is tempting to try to save a few pounds by attempting a DIY boiler repair or replacement. However, with gas boilers, this is not safe or legally permitted in the UK. In some cases, amateur attempts to fit and/or maintain gas boilers can be fatal. This article will look at the dangers and why you should always leave it to professionals.

Gas boilers must be installed by a Gas Safe registered engineer. The Gas Safe Register is the official list of gas engineers who are qualified to work safely and legally on gas appliances. It is illegal for someone to carry out gas work in the UK if they are not Gas Safe registered. If someone does attempt a DIY job or hires an unqualified person to perform it, both may be liable for prosecution if something goes wrong or someone is injured or killed in an accident.

Why Must You Be Qualified to Carry Out Gas Work?

Gas engineers must be qualified to ensure the safety of installations and to make sure that the gas is properly carried away from the boiler and vented properly. All gas work must adhere to the current regulations and standards, which include the Gas Safety (Installation and Use) Regulations 2019. When the boiler is installed, the engineer will check it for any potential risks and faults. They will make sure the boiler complies with current legal requirements and any manufacturer's instructions.

The Potential Hazards of Fitting a Gas Boiler DIY

Attempting a DIY installation could put you, your family and the surrounding environment at serious risk of an explosion or leak due to improper insulation, connection, venting or understanding of the general safety measures. Carbon monoxide poisoning can also be fatal. An untrained person may not notice that there is a problem with the flue, the combustion process or the ventilation, leaving you open to dangerous levels of carbon monoxide.

The Importance of Professional Installation

Having a professional engineer install your boiler means you get peace of mind that your boiler meets all safety regulations and is installed correctly and efficiently. The engineer will be able to detect any potential problems before anything can go wrong and advise on maintenance and energy-saving methods. Most boiler manufacturers even require a professional engineer to install their products, so if you don’t use one, your warranty may become invalid.

Does the Same Apply to Oil and Electric Boilers?

Electric boilers may be easier to install than gas boilers, but you should still use a qualified electrician to do the job. As electric boilers use high-voltage electrical components, the risk of electrocution is high. Oil boilers should be installed by a qualified engineer, as the fuel line needs to be fitted correctly, using a proper sealing material. An oil leak could be extremely hazardous, as well as damaging to your property. 

In conclusion, attempting a DIY repair or installation of a boiler is not only dangerous but illegal in the UK. To make sure your boiler is safe, efficient and meets all the legal requirements, it is best to hire a qualified Gas Safe registered engineer to carry out the work.
