Peace of mind

Every Flow boiler comes with 24 hours a day, 363 days a year support. Whether you’re in your warranty or not, if you experience any issues with your boiler, our team will be here to help.

Cast iron guarantees

The Flow boiler comes with a five year manufacturer’s warranty on the boiler itself. It also comes with a five year warranty on the electricity-generating power module inside the boiler. However, the warranty on the power module will be extended for up to 10 years if you continue to stay with Flow for your home energy, making sure your boiler keeps on generating well into the future.

Servicing and repairs

Flow provides repair and maintenance services via a network of knowledgeable, technically gifted and courteous Gas Safe registered engineers across the country. Any Flow engineer who visits your property will have undergone rigorous product training and will be an expert on the Flow boiler.   And, of course, they’ll work to ensure that they service or fix your boiler with the minimum of disruption.  We offer a 24 hours a day, 363 days a year service.  So as well as a ground-breaking, electricity-generating boiler, we’ll also provide you with complete peace of mind.
