Keston Boiler Warranty 2021

What is a boiler warranty?

Boiler warranties are a promise from the manufacturer that for a certain amount of time after your boiler is installed, they'll be on hand to repair a fault. For this reason, the warranty is just as important as the boiler itself and can provide great peace of mind.

You'll find that warranty periods tend to last between 1-10 years but the length of the warranty isn't the only thing to consider. Thanks to terms and conditions, that vary from manufacturer to manufacturer, you might not be entitled to everything you thought you were.

That's why it's important to get as much information about what you'll be entitled to during a warranty period as possible. To help you out, we've put together this guide so you'll know what's offered under a Keston warranty.

Who are Keston?

With their roots going back to 1928, Keston have grown to now offer a full range of domestic and commercial boilers. Their products are highly efficient, and go through rigorous research and development to ensure they're delivering a reliable heating system. Find out more about Keston and their range of boilers on Boiler Guide.

Standard Keston warranty

The warranty of Keston boilers varies depending on the model but from 1st January 2018, the standard warranty of their Combi and System boilers was increased to 5 years.

How to extend the warranty

If your Combi or System boiler is installed with a Keston System Filter and gets registered at the same time as the boiler, then the warranty will be extended to 7 years.

What's covered by the warranty?

While under warranty, Keston will repair or replace the boiler without charge if it encounters a mechanical or electrical breakdown, as a result of defective workmanship or materials.

Terms and conditions

To remain within the terms of the warranty, the installation must be carried out by a Gas Safe registered engineer, and be the Keston boiler must be serviced annually from then on for the length of the warranty.

How to register your warranty

Your new boiler must be registered with Keston within 30 days of the installation and can be done online.
