DIY vs Professional Gas Boiler Installation: Which is Better?

Are you considering installing a gas boiler? Perhaps you’re wondering whether to do it yourself or hire a professional. There are pros and cons to both approaches. In this article, we explore each option to help you decide which is better for you.

DIY Gas Boiler Installation


  • Cost-saving: Installing your gas boiler yourself can save you money on labour costs.
  • Satisfaction: If you’re a DIY enthusiast, you may enjoy the satisfaction of completing the project yourself.
  • Flexibility: You can work on the project at your own pace and on your own schedule.


  • Safety risks: Gas boiler installation requires specialised knowledge and training. Attempting to do it yourself can put your safety and that of your family at risk.
  • Legal requirements: Gas boiler installation is subject to strict regulations. If you don’t comply with these regulations, you could face legal consequences.
  • Warranty: Most gas boiler manufacturers require professional installation for their warranty to be valid. Installing the boiler yourself could void the warranty.

Professional Gas Boiler Installation


  • Safety: A professional installer has the knowledge, training and equipment to ensure the installation is safe and meets legal requirements.
  • Warranty: Professional installation ensures the manufacturer’s warranty is valid, giving you peace of mind.
  • Expertise: Professional installers have experience and expertise that DIY enthusiasts may lack.


  • Cost: Hiring a professional installer can be more expensive than doing it yourself.
  • Scheduling: You may have to schedule the installation around the installer’s availability.
  • Less control: You may not have as much control over the project as you would if you were doing it yourself.

Which is Better?

Ultimately, the decision whether to install your gas boiler yourself or hire a professional depends on your experience, skills, and comfort level. If you have the knowledge and experience to install the boiler safely and comply with regulations, doing it yourself could save you money. However, if you’re unsure or lack the necessary skills, hiring a professional is the safer and more reliable option.
